PedBotLab: A Novel Video Game–Based Robotic Ankle Platform Created for Therapeutic Exercise for Children With Neurological Impairments

Aims Assess the potential benefits of using PedBotLab, a clinic based robotic ankle platform with integrated video game software, to improve ankle active and passive range of motion, strength, selective motor control, gait efficiency, and balance. Methods Ten participants with static neurological injuries and independent ambulation participated in a 10-week pilot study (Pro00013680) to assess feasibility and efficacy of PedBotLab as a therapeutic device twice weekly. Isometric ankle strength, passive and active ankle range of motion, plantarflexor spasticity, selective motor control of the lower extremity, balance, and gait speed were measured pre- and post-trial. Results Statistically significant improvements were seen in flexibility, active range of motion, and strength in multiple planes of ankle motion. Ankle dorsiflexion with knee flexion and knee extension demonstrated statistically significant results in all outcome measures. No significant changes were observed in gait speed outcomes. Conclusions The use of PedbotLab can lead to improvements in ankle strength, flexibility, and active range of motion for children with static neurological injuries. Future studies aim to evaluate the effect on gait quality and work toward developing a home-based device.

Randomized controlled trial of compressive cryotherapy versus standard cryotherapy after total knee arthroplasty: pain, swelling, range of motion and functional recovery

BackgroundAfter total knee arthroplasty (TKA), patients have limited knee range of motion (ROM), trophic changes and pain. Cryotherapy and compression are recommended in the literature, but no study has shown that cryotherapy and compression combined leads to better results than cryotherapy alone. The primary objective was to compare knee ROM after 21 days of rehabilitation post-TKA between patients who underwent rehabilitation with compressive cryotherapy with those who had cryotherapy alone. The secondary objectives were to compare other trophic, pain and functional outcomes.MethodsForty patients were randomized into two groups: Standard Cryotherapy (SC = 20, median age 77 years), which applied cold packs along with their rehabilitation; and Compressive Cryotherapy (CC = 20, median age 76 years), which received cold compression. Knee joint’s passive and active ROM (primary outcome) were measured with a goniometer. Knee’s circumference, fluctuation test, pain at rest and during activity, 6-minute walking test (6MWT) and KOOS questionnaire were secondary outcomes. The groups were compared on D1 (baseline) and D21 of rehabilitation. A survival analysis has compared the groups on D1, D8, D15, D21.ResultsAll subjects had a significant improvement in all the parameters on D21 relative to D1 (p < .05), except for pain at rest (p = .065 for CC and p = .052 for SC). On D21, the CC group had a significantly larger improvement in the joint effusion (p = .002), pain during activity (p = .005), 6MWT (p = .018) and KOOS (p = .004) than the SC group. Based on the survival analysis, the CC group had significantly faster improvement in the joint ROM (p = .011 for flexion and p = .038 for extension) and knee circumference (p = .013) than the SC group.ConclusionsBoth cryotherapy methods improved joint ROM, trophic changes, pain and function. Adding dynamic compression to a cryotherapy protocol provided further benefits: a significantly faster improvement in passive knee flexion ROM, a greater reduction of swelling, and pain during activity. Similarly, walking distance and KOOS questionnaire were significantly better for CC.Trials registrationThe study was registered in the ClinicalTrials.gov database on 14/09/2023 (identifier: NCT06037824).

Efficacy and Safety of High Density LED Irradiation Therapy for Patients With Hand Osteoarthritis: A Single-Center Clinical Study.

To assess the safety and effectiveness of high-density light-emitting diode (LED) irradiation therapy in patients with hand osteoarthritis (OA) and compare the pre- and post-intervention symptoms. Twenty-three patients with hand OA underwent eight sessions of high-density LED irradiation therapy directed at the five most painful areas in the finger joints. Each session lasted for 18 minutes; and the sessions were conducted twice a week, for 4 weeks. We evaluated the degree of pain using the visual analogue scale, ring size, and passive range of motion (flexion+extension) for two most painful joints from the baseline to post-therapy (weeks 4 and 6). High-density LED irradiation therapy significantly reduced the pain posttreatment compared with that observed at the baseline (p<0.001). Although improvements were observed in ring size and joint range of motion at 4 and 6 weeks, they were not statistically significant (p>0.05). No adverse events were observed. We examined the safety and effectiveness of high-density LED irradiation therapy in reducing pain and hand swelling and improving joint mobility in patients with hand OA. These results suggest that high-density LED irradiation therapy has the potential to be an important strategy for managing hand OA.

Role of ultrasound guided suprascapular nerve block aided mobilization physiotherapy in frozen shoulder recovery: a prospective study

Background: Frozen shoulder is debilitating condition marked by progressive shoulder pain and restricted mobility, affecting sleep and activities of daily living of a person. The objective of this study was to evaluate the efficacy of USG guided suprascapular nerve block aided mobilization physiotherapy for management of frozen shoulder so as to improve the quality of living of patients. Methods: This prospective interventional study was conducted at the Department of Orthopaedics of a teaching institute of Central India from January 2021 to April 2023 after obtaining ethical clearance. Patients diagnosed with frozen shoulder and giving written consent were included in this study after considering the inclusion and exclusion criteria. Baseline demographics, symptom duration, degree of active and passive shoulder range of movement, Shoulder pain and disability index (SPADI) score were documented on day of presentation (preintervention) after which USG guided suprascapular nerve block was given. Post SSNB, 10 sessions of supervised mobilization physiotherapy was given. SPADI scores and degree of active and passive range of movement were noted at 3rd, 6th and 12th week and compared using statistical tests namely repeated measure ANOVA and chi square test of independence. Results: A total of 54 patients enrolled in the study after meeting inclusion criteria, only 46 completed the follow up and their mean SPADI pain score and mean SPADI disability score at presentation significantly reduced at 12 weeks post intervention. Range of flexion, abduction and external rotation of shoulder also showed significant increase (p value&lt;0.05). Number of participants with severe restriction of shoulder internal rotation also decreased after SSNB aided physiotherapy. Conclusions: USG guided suprascapular nerve block aided physiotherapy exercise schedule is a safe and effective outpatient treatment for frozen shoulder providing early pain relief and improving shoulder mobility.

Efficacy of Dashmool Vasti as an adjuvant therapy with the standard of care (modern + physiotherapy) in the rehabilitation of stroke as compared to standard of care – a clinical trial protocol

Background Stroke is ischemia and neurological dysfunction caused by acute brain circulation loss. It causes acute localized neurological abnormalities such as weakness, sensory deficit, or language issues that require long-term treatment. These deficiencies harm the patient and their family psychologically, socially, and economically. Thus, combination treatment can rapidly rehabilitate such patients. Detoxification methods like Ayurvedic medicated enema help stroke pathophysiology. Physical modalities in physiotherapy have been shown to facilitate normal movement and function on the stroke patient’s affected side, increasing independence with everyday duties. A stroke patient may benefit from Dashmoola Niruha Basti, Function Electrical Stimulation (FES), and Motor Relearning Programme (MRP). Aim &amp; Objectives This study compares the adjuvant role of Dashmoola Basti with MRP and FES in stroke recovery. The main goals of this study are to assess and compare the adjuvant role of Dashmoola Basti with standard control over sensorimotor function of lower extremities, static and dynamic balance in stroke patients; gait parameters; resistance experienced during passive range of motion; quality of life of patients; Barthel Index; Modified Ashworth Scale; and Fuglmeyer assessment, Single Limb Stance Test, Functional Reach Test. Methods A total of 40 patients will be enrolled and divided randomly into two equal groups. In Group A (control), standard treatment (modern + physiotherapy) will be prescribed for one month. In Group B (interventional group), Dashmoola Basti will be added to the aforementioned standard treatment for one month. Expected results Improvement in Fuglmeyer assessment, Single Limb Stance Test, Functional Reach Test, quality of Life of Patients, Barthel Index, Modified Ashworth scale, and National Institute of Health (NIH) stroke-scale-score will be observed and recorded. Conclusions Results and conclusions will be derived according to the data collected in case record form and assessment sheets filled at baseline and follow-up visits. Trial registration CTRI/2021/10/037445 dated 21.10.2021.

Range of motion at 6 weeks is an independent risk factor for non-healing at 6 months after arthroscopic supraspinatus repair.

PURPOSE: This study aimed to analyze the effect of the range of motion (ROM) progression pattern on healing after supraspinatus (SSN) repair. HYPOTHESIS: We hypothesized that a faster ROM recovery in the immediate postoperative period would be detrimental for tendon healing. Methods: This was a retrospective study of prospective collected data. All primary arthroscopic SSN repairs for full-thickness tears, with retraction Patte grade &lt; 2, fatty infiltration Goutallier grade &lt; 3 and no glenohumeral osteoarthritis were eligible. Patients who did not attend all follow-ups were excluded. One surgeon performed all arthroscopic repairs using a double-row technique. All patients followed the same rehabilitation protocol with an abduction pillow and passive ROM for 6 weeks. One observer assessed all patients preoperatively and at 1.5, 3 and 6 months postoperatively. Collected outcome measures included: ROM, Visual Analogue Scale (VAS) for pain and Constant Score (CS). Repair integrity was evaluated at 6 months by ultrasound. 2 groups were established based on repair integrity (healed/non-healed). A multivariable analysis was performed to assess potential confounding factors and ROC curve analysis was used to identify predictive thresholds for non-healing. Results: Of 1397 consecutive SSN repairs, 169 were excluded and 1207 were finally included. The overall healing rate was 87.3%. All preoperative outcome measures were similar between groups. Non-healed repairs at 6 months were slightly younger (57.8±7.9 vs 61.6±8.8, p &lt; 0.001) and had a faster postoperative ROM recovery pattern. This difference was most distinct at 6 weeks in passive anterior elevation (AE) (143±22 vs 128±26, p &lt; 0.001) and external rotation (ER) (32±17 vs 23±17,p &lt; 0.001) but was fully compensated by 6 months. VAS pain and CS at each follow-up were similar between groups. Multivariable analysis confirmed 6-weeks passive EA (OR:1.36) and ER (OR:1.16) as independent risk factors for non-healing. The non-healing rate increased when 6-weeks passive EA &gt;140° (20.4 vs 7.9%) and ER &gt; 30° (18.4 vs 8.8%). Conclusions: In a large cohort of isolated arthroscopic SSN repairs treated with the same surgical technique and rehabilitation protocol, a faster postoperative ROM progression pattern, reflected by higher 6-weeks AE and ER, was associated with an increased rate of non-healing. This study illustrates the benefit of a conservative rehabilitation protocol on tendon healing without affecting ROM at 6 months.

High satisfaction rate and range of motion can be expected in frozen shoulder after awake manipulation with brachial plexus block

BackgroundAdhesive capsulitis (AC) is a disease of the glenohumeral joint that is characterized by pain and both passive and active global stiffness with a slow and insidious onset. The disease can occur spontaneously (primary AC) or it can be secondary to other comorbidities, surgery, or trauma, such as fracture or dislocation. Multiple treatment approaches have been suggested: intra-articular steroid injection, physical therapy, manipulation under total anesthesia, and arthroscopic or open surgery. Shoulder manipulation under anesthesia is usually proposed to patients that suffer from severe AC and have already undergone several nonoperative treatments without benefit. Different techniques have been proposed. This study presents our manipulation technique and the clinical results we achieved after shoulder mobilization under brachial plexus block in patients with phase III primary AC.Materials and methodsA retrospective cohort study was performed on a sample of 110 patients with phase III AC who were treated with this manipulation and followed up for 1 year. Patients underwent two assessments—before the procedure (T0) and 4 months after it (T1)—based on the Numerical Rating Scale, Simple Shoulder Test, and joint range of motion to assess shoulder pain, function, and joint articulation, respectively. Furthermore, the patients had to express their degree of satisfaction with the procedure and the results achieved.ResultsPositive and statistically significant results were recorded in terms of pain reduction (ΔNPRS = − 5.4; p < 0.01) and improved functionality (Simple Shoulder Test Δ = 5; p < 0.01). Passive range of motion was statistically significantly increased for each movement at T1. Large increases were observed in extrarotation range of motion (ROM): R1 (Δ = 77.5°) and R2 (Δ = 70°), whereas little improvements were observed in intrarotation ROM. Patients achieved satisfying functional and articular recovery in all cases. Complications that needed further treatment occurred in three cases: a brachial plexus injury, a glenoid flake fracture, and persistent pain and stiffness.ConclusionsIn this study, we proposed a standardized method of manipulation under brachial plexus block for patients affected by phase III adhesive capsulitis. The technique was applied among a large cohort of patients, who reported a high satisfaction rate and range-of-motion recovery after 4 months. This could represent an alternative treatment to surgery that has a shorter timeline and does not require patient hospitalization.Level of evidence: Level III, retrospective cohort study.

Effect of Isometric Strengthening Exercise Combined with Interferential Current on Pain among Patients with Knee Osteoarthritis: Experimental Study

Background: Osteoarthritis, a degenerative disease, is the gradual breakdown of the articular cartilage in the joint.Knee osteoarthritis is more prevalent in women than men which causes pain and discomforts. The intention of thisstudy is to find out the effect of isometric strengthening exercises combined with interferential therapy on pain inpatients with knee osteoarthritis.Purpose: To find out the effect of isometric strengthening exercises combined with interferential therapy in themanagement of knee osteoarthritis patients.Materials and Methods: Thirty individuals aged above 45 years of both genders with mild or moderate osteoarthritisparticipated in the study. The individuals were assigned in single groups. They received interferential therapyand performed isometric strengthening exercises for 4 weeks. Pain, Active range of motion (AROM), Passiverange of motion (PROM) and functional state of the subjects were evaluated by Numerical Pain Rating Scale(NPRS), universal goniometer and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC),respectively. The entire process was performed from November 2022 to March 2023.Result: The interventional group showed a considerable difference in each criterion (NPRS, AROM, PROM, andWOMAC). Isometric exercise and IFT was found to be effective in reducing pain in knee osteoarthritis.Conclusion: At the commencement of the four-week intervention plan, isometric exercise and interferentialtherapy showed a marked outcome on pain and functional state of subjects with osteoarthritis in the knee.

Comparing the Effects of the Postural Restoration Exercises with and without Core Stability Exercises in Patients with Non-Specific Chronic Low Back Pain

Introduction: This study compares the effect of postural restoration (PR) exercises with and without core stability exercises on the pain, intensity, function, quality of life (QoL), and passive range of motion (PROM) at lumbo pelvic-femoral complex in patients with nonspecific chronic low back pain.&#x0D; Materials and Methods: This was an interventional type of randomized clinical trial study. The participants were 45 female patients (48.1±6.11 years, 161.4±5.06 cm height, 65.08±6.9 kg weight, and 24.9±2.8 body mass index). They were randomly divided into three equal groups: Group 1=PR exercises and core exercises, group 2=PR exercises, and group 3=control group. Pain intensity, function, QoL, and PROM were measured with the visual analog scale, Oswestry disability index, short form-36 questionnaire, and goniometer. The analysis of covariance was used to compare the means in the study groups before and after the intervention. The intervention groups performed the exercises for six weeks.&#x0D; Results: The results showed a significant difference between the QoL, pain intensity, function, and PROM of left hip adduction in the group with PR exercises with and without core exercises and control (P=0.000). In the PR group with core exercises (P=0.001) and without core exercises (P=0.001), a significant increase was observed in the adduction of the left hip. There was no significant difference between the function (P=0.850), pain (P=0.120), QoL (P=0.328), and PROM (P=0.094) in the intervention groups.&#x0D; Conclusion: PR exercises with and without core stability are equally effective in reducing pain and improving function, QoL, and hip adduction range of motion in women with left anterior interior chain patterns.

Evaluation of early effectiveness of local infiltration anesthesia with compound betamethasone in total knee arthroplasty

To evaluate the early effectiveness of local infiltration anesthesia (LIA) with compound betamethasone in total knee arthroplasty (TKA). The clinical data of 102 patients with knee osteoarthritis who were treated by TKA and met the selection criteria between May 2022 and March 2023 were retrospectively analyzed. They were divided into control group and study group according to whether LIA preparation was added with compound betamethasone, with 51 cases in each group. There was no significant difference of baseline data, such as age, gender, body mass index, operative side, preoperative range of motion (ROM), Knee Society Score (KSS), white blood cell (WBC), and hematocrit between the two groups ( P>0.05). The intraoperative total blood loss and hidden blood loss were recorded, and WBC was recorded on the 1st, 2nd, and 3rd days after operation. Pain was assessed by visual analogue scale (VAS) score on the 1st, 2nd, and 3rd days after operation and morphine intake milligrames equivalent within 48 hours after operation. Passive ROM, maximum extension and flexion angles of knee joint were measured on the 3rd day after operation; the early postoperative complications were recorded. There was no significant difference in total blood loss and hidden blood loss between the two groups ( P>0.05). The postoperative pain levels in both groups were relatively mild, and there was no significant difference in VAS scores in the first 3 days after operation and in morphine intake milligrams equivalent within 48 hours after operation between the two groups ( P>0.05). The WBC in the first 3 days after operation was significantly improved in both groups ( P<0.05). The WBC in the study group was significantly higher than that in the control group on the 1st and 2nd days after operation ( P<0.05), but there was no significant difference between the two groups on the 3rd day after operation ( P>0.05). On the 3rd day after operation, the maximum extension angle of knee joint in the study group was smaller than that in the control group, while the maximum flexion angle and passive ROM of knee joint in the study group were larger than those in the control group, and the differences were significant ( P<0.05). There were 6 cases of fever and 17 cases of deep venous thrombosis in the control group, and 1 case and 14 cases in the study group, respectively. There was no poor wound healing and periprosthetic joint infection in the two groups, and there was no significant difference in the incidence of complications between the two groups ( P>0.05). The application of compound betamethasone in LIA during TKA is a safe and optimal strategy to promote the early postoperative rehabilitation of patients.

Improved joint function when reaching behind the back is associated with patient reported outcomes in individuals with rotator cuff tears following exercise therapy

BackgroundReaching behind the back is painful for individuals with rotator cuff tears. The objectives of the study were to determine changes in glenohumeral kinematics when reaching behind the back, passive range of motion (RoM), patient reported outcomes and the relationships between kinematics and patient reported outcomes following exercise therapy. MethodsEighty-four individuals with symptomatic isolated supraspinatus tears were recruited for this prospective observational study. Glenohumeral kinematics were measured using biplane radiography during a reaching behind the back movement. Passive glenohumeral internal rotation and patient reported outcome measures were collected. Depending on data normality, appropriate tests were utilized to determine changes in variables. Spearman's correlations were utilized for associations, and Stuart-Maxwell tests for changes in distributions. FindingsMaximum active glenohumeral internal rotation increased by 3.2° (P = 0.001), contact path length decreased by 5.5% glenoid size (P = 0.022), passive glenohumeral internal rotation RoM increased by 4.9° (P = 0.001), and Western Ontario Rotator Cuff Index and American Shoulder and Elbow Surgeons scores increased by 29.8 and 21.1 (P = 0.001), respectively. Changes in Western Ontario Rotator Cuff Index scores positively associated with changes in maximum active glenohumeral internal rotation and negatively associated with changes in contact path lengths (P = 0.008 and P = 0.006, respectively). InterpretationThe reaching behind the back movement was useful in elucidating in-vivo mechanistic changes associated with patient reported outcomes. Glenohumeral joint function and patient reported outcomes improved, where changes in Western Ontario Rotator Cuff Index scores were associated with kinematics. These findings inform clinicians of functional changes following exercise therapy and new targetable treatment factors.

The Impact of Myofascial Release Therapy and Deep Oscillation Therapy on Hamstring Muscle Length and tone in Children with Spastic Cerebral Palsy: A Comparative Study

BACKGROUND: As a result of restricted joint range of motion due to spasticity in patients with spastic cerebralpalsy, the patient’s ability to regain normal functioning may be hindered.PURPOSE: To evaluate the effectiveness of Myofascial Release Therapy (MFR) versus Deep Oscillation Therapy(DOT) in helping children with spastic cerebral palsy to relax and extend their hamstring range of motion.METHODOLOGY: A total of 32 individuals with spastic cerebral palsy, aged 2 to 10, were recruited for thiscomparative experimental study through a method of random sampling. Sixteen subjects were assigned to eachgroup. Group 1(N=16) received two sessions of MFR with conventional exercise per day, whereas Group 2(N=16)received a single session of DOT with conventional exercise per day. Throughout the course of four weeks, bothgroups got therapy five days per week. A universal goniometer was used to compare the knee extension passiverange of motion (PROM), active range of motion (AROM), and Popliteal angle (POP angle) measurements betweenthe pre- and post-treatment periods. Statistical analyses were conducted using ANOVA 2×2 and Post hoctables.RESULT: Both groups’ post-mean values for each of the dependent variables (AROM, PROM, and POP angle)statistically improved (p&lt; 0.05). Both groups’ mean differences in the PROM and POP angles were statisticallysignificant, and Group 1’s spastic hamstring muscle was more improved than Group 2’s, but both groups’ AROMshowed almost equal improvement.CONCLUSION: In children with spastic cerebral palsy, both MFR and DOT, when combined with conventionaltherapy, reduce spasticity and increase length (AROM &amp; PROM) in the hamstring muscle. However, our studyclearly shows that MFR is more successful than DOT.

High frequency neuronavigated repetitive transcranial magnetic stimulation in post-stroke shoulder pain: A double-blinded, randomized controlled study

ObjectiveThis study aimed to determine the effect of 5Hz neuronavigated repetitive transcranial magnetic stimulation (rTMS) to the affected primary motor cortex (M1) on pain, the effect of pain on activities of daily living, disability, mood, neurophysiological parameters and passive shoulder joint range of motion in patients with post-stroke shoulder pain. DesignTwenty two patients were randomized into an experimental group (rTMS, n=7) who received daily rTMS 5Hz 1000 pulses, five times/week for three weeks (15 sessions) to the affected M1 and a control group (n=11) who received sham stimulation. Outcome measures were Numeric Rating Scale (NRS), Brief Pain Inventory (BPI), Disabilities of the arm, shoulder, and hand questionnaire (Quick DASH), Hospital Depression Anxiety Scale (HADS), joint range of motion (ROM) measurements, neurophysiological parameters. Selected outcome measures were performed before treatment (T0), after the 5th session (T1) of rTMS treatment, after the 10th session (T2), after the 15th session (T3), and four weeks after the end of the treatment (T4). In the analysis of the outcomes, within-group comparisons were performed by using the Wilcoxon or Friedman test and between-group comparisons were performed by using the Mann-Whitney U test. ResultsThere was no statistically significant difference between and within groups in terms of change- and followup scores in the NRS measurements (p>0.05). BPI scale was found to be lower in rTMS group at T0 and T3 (p= 0.010). Quick-DASH scores at T4 were found to be significantly lower in rTMS group (p= 0.032). However, no difference was found within each group over time (p>0.05) and there was no statistical difference between the groups in terms of change scores (T3-T0 and T4-T0) (p>0.05) for BPI and Quick-DASH. In rTMS group, there was a statistically significant difference in shoulder external rotation at T3 compared to the baseline (T0) (p=0.039). However, the magnitude of external rotation change (T3-T0) with the treatment was comparable in the groups. No statistically significant change occurred in both treatment groups in other range of motion measurements. ConclusionHigh frequency neuronavigated rTMS to the affected M1 did not show any significant beneficial effect on pain, activities of daily living, disability, anxiety and depression, neurophysiological measurements and passive ROM over sham stimulation.

Effects of a Virtual Reality Cycling Platform on Lower Limb Rehabilitation in Patients With Ataxia and Hemiparesis: Pilot Randomized Controlled Trial.

New interventions based on motor learning principles and neural plasticity have been tested among patients with ataxia and hemiparesis. Therapies of pedaling exercises have also shown their potential to induce improvements in muscle activity, strength, and balance. Virtual reality (VR) has been demonstrated as an effective tool for improving the adherence to physical therapy, but it is still undetermined if it promotes greater improvements than conventional therapy. Our objective was to compare the effect on lower limb range of motion (ROM) when using VR technology for cycling exercise versus not using VR technology. A randomized controlled trial with 20 patients with ataxia and hemiparesis was carried out. The participants were divided into 2 groups: the experimental group (n=10, 50%) performed pedaling exercises using the VR system and the control group (n=10, 50%) performed pedaling exercises without using VR. Measurements of the active and passive ROM of the hip and knee joint were taken before and after a cycling intervention, which consisted of 3 sessions of the same duration but with progressively increasing speeds (4, 5, and 6 km/h). Repeated measures ANOVAs were conducted to compare the preintervention (Ti) and postintervention (Te) assessments within each group. Additionally, the improvement effect of using the VR system was analyzed by comparing the variation coefficient (Δ = 1 - [Te / Ti]) between the preintervention and postintervention assessments for each group. Group comparisons were made using independent 1-tailed t tests. Significant improvements were shown in active left hip flexion (P=.03) over time, but there was no group-time interaction effect (P=.67). Passive left hip flexion (P=.93) did not show significant improvements, and similar results were observed for active and passive right hip flexion (P=.39 and P=.83, respectively). Neither assessments of knee flexion (active left: P=.06; passive left: P=.76; active right: P=.34; passive right: P=.06) nor knee extension showed significant changes (active left: P=.66; passive left: P=.92; active right: P=.12; passive right: P=.38). However, passive right knee extension (P=.04) showed a significant improvement over time. Overall, although active and passive ROM of the knee and hip joints showed a general improvement, no statistically significant differences were found between the groups. In this study, participants who underwent the cycling intervention using the VR system showed similar improvement in lower limb ROM to the participants who underwent conventional training. Ultimately, the VR system can be used to engage participants in physical activity.

Therapeutic effects of extracorporeal shock wave therapy on patients with spastic cerebral palsy and Rett syndrome: clinical and ultrasonographic findings

BackgroundExtracorporeal shock wave therapy (ESWT) is reportedly effective for improving spasticity and motor function in children with cerebral palsy (CP). Because late-stage Rett syndrome has a similar presentation, this study aimed to investigate the effects of ESWT on these two diseases.Material and MethodsPatients diagnosed with spastic CP and Rett syndrome received 1500 impulses of ESWT at 4 Hz and 0.1 mJ/mm2, on their spastic legsonce weekly for a total of 12 weeks. Outcomes were assessed before and 4 and 12 weeks after ESWT. Clinical assessments included the Modified Ashworth Scale (MAS), passive range of motion (PROM), and Gross Motor Function Measure 88 (GMFM-88). Ultrasonographic assessments included muscle thickness, acoustic radiation force impulse (ARFI), and strain elastography.ResultsFifteen patients with CP and six with Rett syndrome were enrolled in this study. After ESWT, patients with CP showed significant clinical improvement in the MAS (P = 0.011), ankle PROM (P = 0.002), walking/running/jumping function (P = 0.003), and total function (P < 0.001) of the GMFM-88. The patients with Rett syndrome showed improved MAS scores (P = 0.061) and significantly improved total gross motor function (P = 0.030). Under ARFI, patients with CP demonstrated decreased shear wave speed in the gastrocnemius medial head (P = 0.038). Conversely, patients with Rett syndrome show increased shear-wave speeds after ESWT.ConclusionOur study provides evidence that a weekly course of low-dose ESWT for 12 weeks is beneficial for children with both CP and Rett syndrome, with the clinical effects of reducing spasticity and improving the gross motor function of the lower limbs. The ARFI sonoelastography reveals improvement of muscle stiffness in patients with CP after ESWT, but deteriorated in patients with Rett syndrome. The diverse therapeutic response to ESWT may be caused by the MECP2 mutation in Rett syndrome, having a continuous impact and driving the pathophysiology differently as compared to CP, which is secondary to a static insult.Trial registration IRB 201700462A3.

Comparative Analysis of Bone Mineral Density of the Lumbar Spine, Hip, and Proximal Humerus in Patients with Unilateral Rotator Cuff Tears.

The proximal humerus, a common site for osteoporotic fractures, is frequently overlooked in osteoporosis evaluations. This study aimed to evaluate the relationship between the conventional bone mineral density (BMD) measurement (at the lumbar spine and femur) and the BMD measurement at both proximal humeri (the asymptomatic side and the side with a rotator cuff tear [RCT]) in patients with unilateral RCT. Furthermore, we investigated clinical features indicative of osteoporosis in RCT patients and assessed the utility of proximal humerus BMD measurements. From April 2020 to September 2020, 87 patients who underwent arthroscopic repairs for unilateral RCTs were examined for age, onset, body mass index, menopause duration, passive range of motion, global fatty degeneration index, and RCT and retraction size. The regions of interest (ROIs) for the conventional BMD included the lumbar spine, femur neck, femur trochanter, and total femur. For the proximal humerus BMD, the ROIs included the head, lesser tuberosity, greater tuberosity (medial, middle, and lateral rows), and total humerus. The conventional BMD of the lumbar spine, femur neck, femur trochanter, and femur total were 1.090, 0.856, 0.781, and 0.945 g/cm2, respectively. The head, lesser tuberosity, greater tuberosity (medial, middle, and lateral rows), and total BMD of the asymptomatic-side proximal humerus were 0.547, 0.544, 0.697, 0.642, 0.554, and 0.610 g/cm2, respectively. The average of proximal humerus BMD was significantly lower than that of conventional BMD (p < 0.001). All ROIs BMD of the RCT-side proximal humerus were 0.497, 0.507, 0.619, 0.598, 0.517, and 0.560 g/cm2. There was no correlation between the conventional BMD and each proximal humerus BMD. All ROI BMD of the RCT-side proximal humerus was not significant in the multiple regression analysis with age, onset, body mass index, passive range of motion, global fatty degeneration index, and RCT and retraction size (p > 0.05). The proximal humerus BMD showed a completely different trend from that of conventional BMD and had no significant association with clinical features. Therefore, the proximal humerus BMD needs to be measured separately from the conventional BMD, as it may provide important information before rotator cuff repair surgery.

Importance of the assessment of knee joint function after a stroke

Purpose This study aimed to assess knee joint function in post-stroke patients using wireless motion sensors and functional tests. This type of evaluation may be important for improving gait quality. Methods The study included 25 post-stroke patients (age 53.5 ± 8.4 years) and 25 healthy controls (age 51.1 ± 7.7 years). Knee function was assessed using passive range of motion (PROM), active range of motion (AROM) at any speed, maximum speed AROM (FROM), and joint position sense (JPS). Orthyo® motion sensors and a mobile app were used for measurements. The following functional tests have been used: Five Times Sit-to-Stand Test (FTSST) and Timed Up and Go Test (TUG). Results Before rehabilitation, the average values of PROM (p=0.006), AROM (p=0.005), FROM average (p &lt; 0.001) and maximal velocity (p &lt; 0.001), JPS 30º (p = 0.002), JPS 60º (p = 0.002) and JPS 80º (p &lt; 0.001) were significantly worse in the paretic limb than in healthy people. The applied rehabilitation contributed to improving the PROM and AROM and the average and maximum speed of rapid movement in the knee joint. Proprioception (JPS) also improved. Only the average (p &lt; 0.001) and maximum speed (p &lt; 0.001) in the FROM test in the knee joint of the paretic limb after rehabilitation significantly differed from the values in healthy people. The patients' performance (functional tests) improved after rehabilitation (TUG (&lt; 0.001) and FTSST (&lt; 0.001)), but it did not reach the level of healthy people. Conclusions The function of the knee joint in the paretic limb is significantly impaired and requires inclusion in the therapy plan in the early period after stroke.

Dominant Arm Internal and External Rotation Strength is Related to Arm Pain in Youth Baseball Players.

The prevalence of arm pain in youth baseball players is high with approximately half reporting arm pain during the season, and the number of ulnar collateral ligament reconstructions in youth baseball players is increasing. Few studies have examined the relationship between shoulder strength and passive range of motion (ROM) with arm pain (either shoulder or elbow pain) during throwing, especially in athletes in early adolescence. The purpose of this study was to determine the relationship between shoulder ROM and strength and the presence of arm pain during throwing in youth baseball players. It was hypothesized that less internal rotation (IR) ROM, less total rotational ROM, and lower IR and external rotation (ER) strength would be associated with arm pain. Observational cohort study. Sixty-five youth male baseball players between the ages of 12-15 were enrolled. Shoulder strength (ER, IR, ER/IR strength ratio, scaption) and passive ROM (ER, IR, flexion, horizontal adduction) were collected prior to the start of the spring 2021 baseball season. Players self-reported their arm pain frequency during throwing as never, rarely, sometimes, often, or always. The relationship between reported arm pain frequency during throwing and shoulder ROM and strength measurements was examined. ER (ρ= -0.289, p=0.020) and IR strength (ρ= -0.262, p=0.035) were weakly and negatively correlated with reports of arm pain during throwing. No other clinical variables were associated with reports of arm pain (p ≥ 0.124). In youth baseball players, greater IR and ER strength were associated with less arm pain frequency during throwing, while ROM was not associated with arm pain frequency. Future research should explore these variables prospectively to determine if changes in ROM and strength are related to the development of arm pain in youth baseball players. 3.

Impact of lower limb alignment abnormality (physiologic knee valgus) on the functional recovery outcome of athletes with meniscal injuries.

This study aimed to investigate the impact of lower limb alignment abnormalities, specifically physiological knee valgus, on the functional recovery outcomes of athletes with meniscal injuries. It also examined the factors influencing these abnormalities to provide scientific evidence for treatment and rehabilitation of related sports injuries. We conducted a retrospective study of 118 athletes from Guizhou Normal University, who were divided into two groups based on the presence or absence of lower limb alignment abnormalities. The Simple group comprised athletes with isolated meniscal injuries, while the Combined group included athletes with meniscal injuries and concurrent lower limb alignment abnormalities. We assessed the functional status of both groups and analyzed factors influencing lower limb alignment abnormalities. Of the 118 athletes, 46 (38.98%) exhibited lower limb alignment abnormalities, and 72 (61.02%) did not. No significant differences in general characteristics were found between the groups (all P > 0.05). The Combined group displayed higher Visual Analog Scale (VAS) scores and Functional Performance Test (FPT) results (coordinated contraction, shuttle run, CarioCa) compared to the Simple group (P < 0.05). Conversely, joint range of motion (ROM), knee muscle strength (flexors), and International Knee Documentation Committee (IKDC) scores were lower in the Combined group (all P < 0.05). Multivariate logistic regression analysis identified active ROM < 105.32°, passive ROM < 101.66°, and knee muscle strength (flexors) < 84.41 N as risk factors for lower limb alignment abnormalities (P < 0.05), while FPT acted as a protective factor (P < 0.05). The combined testing model demonstrated higher predictive efficacy (AUC = 0.903, 95% CI: 0.852-0.955, P < 0.001). Lower limb alignment abnormalities significantly affect the functional recovery outcomes of athletes with meniscal injuries. Factors such as ROM, knee muscle strength, and IKDC score may pose risks for these abnormalities, whereas FPT can provide protective benefits. Timely detection and correction of lower limb alignment abnormalities during the rehabilitation process from meniscal injuries are crucial to enhance recovery and improve prognosis.

Impacts of COVID-19 pandemic prevention measures to the palliative care in Taiwan.

Prevention measures for palliative care and the provision of discharge planning services for inpatients in Taiwan before and during the COVID-19 pandemic had not been investigated. This study was aimed to investigate the factors associated with heightened palliative care needs and increased mortality rates. This research adopts a retrospective case-control study design. The investigation encompasses patients admitted before the pandemic (from January 1, 2019, to May 31, 2019) and during the COVID-19 pandemic (from January 1, 2020, to May 31, 2020). The case group consisted of 231 end-of-life inpatients during the pandemic, control group was composed of the pool of inpatients with pre-pandemic and matched with cases by sex and age in a 1:1 ratio. The results showed that the prevalence of respiratory failure symptoms (p = 0.004), residing in long-term care facilities (p = 0.017), palliative care needs assessment scores (p = 0.010), as well as the provision of guidance for nasogastric tube feeding (p = 0.002), steam inhalation (p = 0.003), turning and positioning (p < 0.001), percussion (p < 0.001), passive range of motion (p < 0.001), and blood pressure measurement (p < 0.001). Furthermore, the assessment of the necessity for assistive devices, including hospital beds, also exhibited statistically significant variations (p < 0.001). Further investigation of the factors associated with high palliative care needs and the risk of mortality for both the case and control groups. Risk factors for high palliative care needs encompassed assessments of daily activities of living, the presence of pressure ulcers, and the receipt of guidance for ambulation. Risk factors for mortality encompassed age, a diagnosis of cancer, palliative care needs assessment scores, and the provision of guidance for disease awareness. This research highlights the heightened risk of COVID-19 infection among end-of-life inpatients during the COVID-19 pandemic. The findings of this study may advance care planning to alleviate avoidable suffering. To meet the needs of inpatients during pandemic, healthcare professionals should undergo comprehensive palliative care training and receive policy support.
