The efficacy of the Novel Hybrid Passive Spring Damper Ankle Foot Orthosis regard to kinetic and kinematic parameters of patients with Multiple Sclerosis: An intervention study

ABSTRACT Drop foot is a common consequence of Multiple Sclerosis (MS), which may be improved somewhat by an ankle-foot orthosis (AFO). This study aimed to examine the immediate effect of using the recently developed Novel Hybrid Passive Spring Damper AFO (the novel HPSDAFO) on the kinetic and kinematic parameters of patients with MS (PwMS) in the sagittal plane. Twelve PwMS who suffered a unilateral drop foot participated in this study and fitted with the novel HPSDAFO. They walked with the novel HPSDAFO on the affected side and shoe on the affected side at a self-selected speed. Walking by the novel HPSDAFO, the symmetry of all of the evaluated sagittal kinetic and kinematic parameters improved noticeably. The range of ankle plantarflexion and knee flexion increased significantly at the stance phase. Power generation increased at all three joints. The peak of ankle dorsiflexion at early stances and the first peak of knee extension moments increased significantly but decreased at the hip joint. Changes in sagittal ROM, moment, and power generation in the plane and the improved symmetry revealed a more normal walking by using the novel HPSDAFO on the affected limb of PwMS.

Post-treatment Functional Outcomes of Distal Tibiofibular Syndesmosis Injuries With Varying Duration and Method of Stabilization

The purpose of this study was to assess whether the type and duration of screw fixation affects ankle joint functional scores and patient activity levels. We evaluated 55 patients who had undergone surgical treatment for ankle fracture with concomitant distal tibiofibular syndesmosis injury. The follow-up period ranged from 2 years to 4 years and 2 months (mean 36 months). Depending on the time of screw removal, patients were divided into 2 groups (the 8–15-week group-19 patients, and the 16–22-week group-36 patients). There were 17 patients with tricortical and 38 patients with quadricortical syndesmosis fixation. The following parameters were assessed: range of motion, rates of complications, level of pain in visual analogue scale (VAS), and function. In the quadricortical fixation group the range of plantar flexion p = .04 and adduction p = .043 were significantly lower in the operated than in the nonoperated limb. In the patients who had their syndesmotic screws removed after 16–22 weeks, the range of plantar flexion in the operated limb was significantly lower than that in the nonoperated limb. We observed no differences between the evaluated groups in terms of ankle joint mobility, VAS pain levels, functional outcomes, or complication rates. All the analyzed subgroups showed poorer ranges of some types of motion in the ankle and worse functional scale and VAS pain scores after treatment in comparison with those before the injury. We suggest removing the syndesmotic screws after 8–15 weeks, due to the possibility of earlier rehabilitation, faster return to work and physical activity and less burden on the health care system. Tricortical or quadricortical syndesmosis fixation is at the surgeon's discretion.

Effects of running-induced fatigue on joint kinematics and kinetics during overground running: a systematic review and meta-analysis.

This study evaluated the acute fatigue-inducing effect of distance running on kinematics and kinetics during overground running. Standardised mean differences (SMD) with 95% confidence intervals (95% CI) were used to pool data across 16 studies. Effects during consistent (pre- and post-fatigue running speed within ± 5%) versus varied speed running (difference of >5% between running speeds) were analysed separately. There was strong evidence that running-induced fatigue significantly increases ground contact times at consistent running speeds (SMD 0.52 [95% CI 0.22, 0.82]) and moderate evidence that step length shortens at varied running speeds (SMD -1.27 [95% CI -1.79, -0.75]). There was strong evidence that fatigue does not change peak: hip and knee flexion angles, hip adduction angle, hip and knee internal rotation angles, hip and knee extension moments, hip and knee abduction moments, knee abduction angle, knee flexion and extension moments, knee adduction moment, rearfoot eversion angle, and plantarflexion moments, or knee flexion and plantarflexion range of motion during stance. Running-induced fatigue increases contact times and reduces step length, whereas lower-body joint angles and moments are unchanged. Minimising changes in stride parameters could provide a mechanism for reducing the effects of fatigue on running performance.

Causal Relationships Between Physical Activity and Arthrokinematic Integrity of the Ankle Joint-Foot Complex Across Normal and Pathological Phenomena: A Case-Control Analysis.

Introduction Muscles, ligaments, tendons, bones, and cartilage undergo age-related changes, affecting the foot-ankle joint complex biomechanics in both genders. While international studies have extensively researched these dynamics, Indian studies are limited. Our study aims to fill this gap by analyzing the anthropometric and biomechanical function of the foot-ankle joint complex in normal individuals and those with painful pathologies at All India Institute of Medical Sciences (AIIMS) Rajkot's OPD. Methods In a two-year case-control study of the cross-sectional type conducted at AIIMS Rajkot's OPD, 158 patients with similar pain intensity on the Numeric Pain Rating Scale were examined. Anthropometric and biomechanical measurements were taken for both affected and non-affected foot and ankle joints. Cases comprised patients with foot and ankle joint pain, while controls were selected based on predefined criteria and were without such pain. Ethical approval was acquired from the Institutional Ethical Committee of AIIMS Rajkot. Results The sprain of the ankle joint and foot was the most common musculoskeletal pathology (65 out of 158 cases, i.e., 41.13%) affecting the ankle joint-foot complex. Patients involved in occupations requiring higher physical inactivity suffer more commonly from ankle joint-foot pathologies. The mean difference in the range of motion, i.e., dorsiflexion, plantar flexion, inversion, and eversion, between affected and non-affected feet was found to be lower in the patients who belonged to occupations involving low physical activity compared to those patients having occupations with high physical activity. Conclusion Reduced physical activity increases the stiffness and reduces the flexibility of the tendons, muscles, and ligaments of any joint (the ankle joint-foot complex in this study) and is associated with a higher incidence of musculoskeletal pathologies.

Can the Achilles tendon regenerate completely following percutaneous tenotomy in older children with clubfoot?

The aims of the study were to document the outcomes of percutaneous Achilles tenotomy (pAT) performed in older children with clubfoot, by assessing the clinical, functional and ultrasonographic evidence of Achilles tendon regeneration. A retrospective case series of older children with clubfoot treated between August 2011 and July 2020 was studied. Clinical assessment of ankle range of motion and calf strength, functional assessment of triceps surae muscle endurance by single leg heel-rise test, and ultrasonographic assessment of Achilles tendon echotexture and dimensions to assess tendon regeneration were performed. Percutaneous Achilles tenotomy was performed on 31 children (48 clubfeet) at a mean age of 5.24 ± 2.14years (1-10.2years). At a mean follow-up of 4.86 ± 1.97years, all children demonstrated normal calf strength with mean dorsiflexion range of 13.64° (0-25°) and mean plantarflexion range of 37.95° (10-40°). The heel-rise endurance test was completed by 27 children with mean 25.85 heel rises/minute (range 17-30) and mean height of heel rise of 6.29cm (range 4-10cm). Normal fibrillar tendinous echotexture with homogenous echogenicity was seen on ultrasonography in 41 feet (85.4%) with mean tendon width of 9.7mm (3.3-16mm) and thickness of 5.1mm (1.8-15mm), comparable with unaffected feet. Clinical, functional and ultrasonographic parameters unequivocally demonstrate complete regeneration of the Achilles tendon, when pAT is performed in older children with delayed-presenting idiopathic clubfoot treated using Ponseti principles.

The NewGait Rehabilitative Device Corrects Gait Deviations in Individuals With Foot Drop.

The purpose of this quasiexperimental study was to test the effects of wearing the NewGait rehabilitative device on walking abilities in individuals with foot drop. The study involved 16 participants with foot drops caused by stroke (11 participants), multiple sclerosis (one participant), and peripheral neuropathies (four individuals). During a single testing session, participants walked 12 m at their self-selected speed in four experimental conditions: walking without any orthotic device; walking while wearing a regular plastic posterior leaf ankle foot orthosis (AFO); walking with the NewGait device assisting ankle dorsiflexion only; and walking with the NewGait device assisting the hip, knee, and ankle joint motions. Body motions during walking were recorded using a 3D system for motion analysis and analyzed with a set of spatiotemporal and kinematic parameters and a gait decomposition index. The gait decomposition index indicated sagittal interjoint coordination in the three joint pairs (hip-knee, knee-ankle, and hip-ankle) of the paretic (foot drop) leg during walking and was validated in a previous study. Overall, wearing all three orthotic devices improved the gait velocity, ankle dorsiflexion, and foot clearance compared to gait trials in which no assistive devices were used. However, wearing the AFO significantly restricted the plantarflexion range of motion and decreased interjoint coordination as measured by joint decomposition. In contrast, the NewGait device altered the ankle plantarflexion motions but also increased coordinated movement (reduced the decomposition) in most lower-extremity joint pairs and conditions. Therefore, the NewGait rehabilitative device can be considered superior to a regular AFO in correcting gait deviations caused by foot drop.

Comparative Effects of Active Release Technique and Positional Release Therapy in Female Students with Tightened Calf Muscles

Background: Prior research has established that regular use of high-heeled shoes significantly alters the gait pattern, impacts ankle joint motion, increases joint forces and moments in the lower extremities, modifies foot pressure distribution, and affects posture and balance. These biomechanical changes can lead to tightened calf muscles and associated discomfort in frequent high heel wearers. Objective: The main objective of this study is to compare the effect of Active Release Technique and Positional Release Therapy in female students with tightened calf muscles. Methods: A randomized clinical trial including 26 subjects by using convenient sampling technique, with subject age ranging from 20-30 years wearing high heels with minimum duration (5 hours a day, 5 times a week and for more than 1 year) with heel height minimum of 2''. The outcome measures were ankle dorsiflexion plantar flexion range of motion measured by goniometer, and pain measured by Numerical Pain Rating Scale. Data was collected for 4 months (Feb-May 2023) from The University of Faisalabad and Government College University Faisalabad. Over four weeks & 3 times per week both groups received ultrasound and traditional Physiotherapy of conventional calf muscle stretching as baseline treatment. Group 1 received Positional Release Therapy, while Group 2 received Active Release Technique. Results: Friedman test showed within-group improvements in NPRS, Dorsiflexion, Plantar flexion, and Cadence (p<0.05) for both groups. Mann Whitney U test revealed significant improvements in NPRS, Dorsiflexion, Plantar flexion, and Cadence at post-treatment (p<0.05) for Positional Release Therapy group more than Active Release Therapy.. Conclusion: Positional Release Therapy (PRT) has more significant effects for calf muscle tightness, exhibiting increased cadence, ankle dorsiflexion, and plantar flexion range of motion, along with significant pain reduction than Active Release Therapy (ART)

Arthroereisis with a Talar Screw in Symptomatic Flexible Flatfoot in Children

Background: Pes planovalgus, or flexible flatfoot, deformity is a common problem in pediatric orthopedic patients. There is no consensus on using the technique of arthroereisis in the treatment of symptomatic pes planovalgus. The aim of our study was to prospectively assess the functional outcomes following symptomatic pes planovalgus treatment with the use of the Spherus talar screw. Methods: Twenty-seven patients (11 females, 16 males), at a mean age of 10.5 years (7–14 years) were included in the prospective study. We assessed the level of physical activity (including sports) based on the University of California, Los Angeles (UCLA) activity scale, a 10-point level-of-activity VAS scale, and the Grimby physical activity scale. Pain was assessed based on a VAS pain scale; foot function was assessed with the revised Foot Function Index (FFI-R); and ankle joint mobility was measured. Results: The mean follow-up period was 18 months (14–26 months). There was a significant improvement in VAS-measured physical activity scores from 5.47 to 7 at follow-up, p = 0.048. There was a significant improvement in UCLA activity scale scores from 4.78 to 6.05 at follow-up, p = 0.045. Pain levels decreased from a mean VAS score of 4.73 prior to surgery to a mean score of 2.73 at follow-up, p = 0.047. The functional FFI-R scores showed a significant improvement from 140 points prior to surgery to 97.75 points at follow-up, p = 0.017. Comparison of the preoperative and follow-up values of the range of plantar flexion, adduction, and abduction in the operated limb also showed no significant changes in those individual parameters. The mean values of dorsiflexion, plantar flexion, adduction, and abduction at the ankle joint at follow-up, compared individually between the operated and non-operated foot showed no statistically significant differences. Conclusions: The use of a talar screw in the treatment of symptomatic pes planovalgus helps reduce pain and improve functional outcomes after treatment. Foot function assessments showed diminished pain, improved levels of physical and sport activity, and no effect on the range of motion after surgery in comparison with preoperative data. Arthroereisis with a talar screw is a valid surgical technique for the treatment of symptomatic pes planovalgus.

15 YEARS ON: A PROSPECTIVE COMPARISON OF PONSETI CASTING VERSUS SURGICAL TREATMENT OF CLUBFOOT

In 2010, we published results of Ponseti versus primary posteromedial release (PMR) for congenital talipes equinovarus (CTEV) in 51 prospective patients. This study reports outcomes at a median of 15 years from original treatment.We followed 51 patients at a median of 15 years (range 13–17 years) following treatment of CTEV with either Ponseti method (25 patients; 38 feet) or PMR (26 patients; 42 feet). Thirty-eight patientsd were contacted and 33 participated in clinical review (65%), comprising patient reported outcomes, clinical examination, 3-D gait analysis and plantar pressures.Sixteen of 38 Ponseti treated feet (42%) and 20 of 42 PMR treated feet (48%) had undergone further surgery. The PMR treated feet were more likely to have osteotomies and intra- articular surgeries (16 vs 5 feet, p<0.05). Of the 33 patients reviewed with multimodal assessment, the Ponseti group demonstrated better scores on the Dimeglio (5.8 vs 7.0, p<0.05), the Disease Specific Instrument (80 vs 65.6, p<0.05), the Functional Disability Inventory (1.1 vs 5.0, p<0.05) and the AAOS Foot & Ankle Questionnaire (52.2 vs. 46.6, p < 0.05), as well as improved total sagittal ankle range of motion in gait, ankle plantarflexion range at toe off and calf power generation. The primary PMR group displayed higher lateral midfoot and forefoot pressures.Whilst numbers of repeat surgical interventions following Ponseti treatment and primary PMR were similar, the PMR treated feet had greater numbers of osteotomies and intra-articular surgeries. Outcomes were improved at a median of 15 years for functional data for the Ponseti method versus PMR, with advantages seen in the Ponseti group over several domains. This study provides the most comprehensive evaluation of outcomes close to skeletal maturity in prospective cohorts, reinforcing the Ponseti Method as the initial treatment of choice for idiopathic clubfeet

Short-term effectiveness of INBONE TM Ⅱ total ankle prosthesis arthroplasty in the treatment of moderate to severe varus-type ankle arthritis

To investigate the short-term effectiveness of INBONE TM Ⅱ total ankle prosthesis arthroplasty in the treatment of moderate to severe varus-type ankle arthritis. The clinical and radiographic data of patients with moderate to severe varus-type ankle arthritis, who were admitted between May 2017 and November 2021 and treated with total ankle arthroplasty (TAA) using INBONE TM Ⅱ prosthesis, was retrospectively analyzed. A total of 58 patients (58 ankles) met the selection criteria and were included in the study. Among them, there were 24 males and 34 females, with an average age of 62.6 years (range, 41-85 years). According to the preoperative tibiotalar angle (TTA), the patients were divided into a moderate varus group (group A, TTA 5°-15°, n=34) and a severe varus group (group B, TTA>15°, n=24). There was no significant difference in gender, side, etiology, preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score, ankle dorsiflexion, plantarflexion, and total range of motion, and tibial lateral surface angle (TLS) between the two groups ( P>0.05). Yet the patients in group A were younger than group B, the degrees of oesteoarthritis (Takakura stage) and ankle pain [visual analogue scale (VAS) score] were milder, and the TTA, talar tilt angle (TT), hindfoot alignment angle (HAA) were smaller while the tibial articular surface angle (TAS) was larger, showing significant differences ( P<0.05). The pre- and post-operative VAS score, AOFAS score, the occurrence of early and late complications, the radiographic parameters of the ankle (TTA, TAS, TT, HAA, TLS), ankle dorsiflexion, plantarflexion, and total range of motion were recorded and compared. All patients were followed up 19-72 months, with an average of 38.9 months. Compared with the preoperative data, the VAS score of all patients significantly decreased ( P<0.05); the AOFAS score, ankle dorsiflexion range of motion, and total range of motion significantly increased ( P<0.05); and the TTA, TAS, TT, HAA, and TLS significantly improved at last follow-up ( P<0.05); but there was no significant difference in plantarflexion range of motion ( P>0.05). Early complications occurred in 13 patients, and only 1 patient underwent revision surgery due to a larger size of the talar component. At last follow-up, there was no significant difference in the difference of clinical parameters before and after operation between the two groups ( P>0.05); there was a significant difference in the difference of other radiographic parameters ( P<0.05) except TLS. No significant difference in the incidence of complications between the two groups was found ( P>0.05). TAA using the INBONE TM Ⅱtotal ankle prosthesis is an effective treatment for moderate or severe varus-type ankle arthritis, and good clinical and radiographic results can be obtained. Correcting bony deformities and balancing soft tissue are the keys to successful surgery.

A comparison of the range of motion and dynamic stability of the ankle joint of athletes with an ankle sprain as compared to healthy controls: A cross-sectional study.

Ankle sprains are the most common lower-leg musculoskeletal injuries, frequently occurring among athletes and other physical activity individuals. The objective of this study was to compare the ankle range of motion and dynamic stability of healthy and injured athletes for their dominant and nondominant legs. A cross-sectional study design was selected to investigate this study with 32 male soccer players with average age: 22.6 ± 3.3 years, weight: 69.6 ± 5.7 kg, height: 176.8 ± 5.32 cm, with a history of a lateral ankle sprain on the dominant leg for the past 2 years. Ankle range of motion was determined using dorsiflexion and plantar flexion by a goniometer. The dynamic stability was determined using the SWAY medical system. An independent t-test was used to study the differences between healthy and injured groups and between dominant and nondominant legs for dynamic stability, dorsiflexion, and plantar flexion range. There were higher significant differences for dynamic stability in healthy participants than in injured participants for their dominant (P = 0.001) and nondominant (P = 0.001) legs. There were significant differences in dynamic stability in the dominant and nondominant leg (healthy [P = 0.033] and injured [P = 0.000] participants). The dominant leg shows higher dynamic stability in healthy group, whereas nondominant leg shows higher dynamic stability in the injured group. The study found significant differences between the injured and sound legs. The injured dominant and nondominant leg revealed a striking disparity in the ankle range of motion. Therefore, the study demonstrated that ankle sprain causes due to less stability of the ankle joint, which limits ankle movements.

Clinical Relevance and Function of Anterior Talofibular Ligament Superior and Inferior Fascicles: A Robotic Study

Background: Ankle lateral ligament sprains are common injuries in sports, and some may result in persistent ankle pain and a feeling of instability without clinical evidence of instability. The anterior talofibular ligament (ATFL) has 2 distinct fascicles, and recent publications have suggested that injury isolated to the superior fascicle might be the cause of these chronic symptoms. This study aimed to identify the biomechanical properties conferred by the fascicles in stabilizing the ankle in order to understand potential clinical problems that may follow when the fascicles are injured. Purpose/Hypothesis: The aim of this study was to determine the contribution of superior and inferior fascicles of the ATFL in restraining anteroposterior tibiotalar resistance, internal external tibial rotation resistance, and inversion eversion talar rotation resistance. It was hypothesized that an isolated injury of the ATFL superior fascicle would have a measurable effect on ankle stability and that the superior and inferior fascicles would restrain different motions of the ankle. Study Design: Descriptive laboratory study. Methods: A robotic system with 6 degrees of freedom was used to test ankle instability in 10 cadavers. Serial sectioning following the most common injury pattern (from superior to inferior fascicles) was performed on the ATFL while the robot ensured reproducible movement through a physiological range of dorsiflexion and plantarflexion. Results: Sectioning of only the ATFL superior fascicle had a significant and measurable effect on ankle stability, resulting in increased internal rotation and anterior translation of the talus, especially in plantarflexion. Sectioning of the entire ATFL resulted in significantly decreased resistance in anterior translation, internal rotation, and inversion of the talus. Conclusion: Rupture of only the superior fascicle of the ATFL may lead to minor instability or microinstability of the ankle joint, without objective clinical findings of gross clinical laxity. Clinical Relevance: Some patients develop chronic symptoms after an ankle sprain without overt signs of instability. This may be explained by an isolated injury to the ATFL superior fascicle, and diagnosis may require careful clinical evaluation and magnetic resonance imaging examination looking at the individual fascicles. It is possible that such patients may benefit from lateral ligament repair despite having no gross clinical instability.

Corrective bandages and daily manipulations for treatment of congenital vertical talus: a thirteen year follow-up

PurposeTo analyze the results of a conservative method for treating congenital vertical talus in children with early start and to know in which cases surgical treatment was needed.MethodsA retrospective analysis of all children diagnosed with idiopathic vertical talus was carried out during the years 2008–2021. Thirty-two children (46 feet) were finally included. Children were treated with serial manipulations, muscle stimulation, and corrective bandages. Age at the time of initiation of treatment, duration of treatment, and correction or not of the deformity without surgical intervention were recorded as variables of interest. The talocalcaneal angle, TAMBA, and ankle range of motion were measured before treatment, after treatment, and at the end of the follow-up period. Statistics decision tree was used to determine which variable best discriminated whether the patient needed surgery. To complement the tree diagram, a two-step cluster analysis was carried out.ResultsAfter treatment, TAMBA and talocalcaneal angle changed from “vertical” to “oblique” category in 45 and 37 feet, respectively. The pathological dorsal flexion of the ankle changed to normal in 37 feet and ankle plantar flexion was normal in 46 feet. These variables showed significant changes between the three measurement moments. The results of the statistics decision tree and cluster analysis indicate that “No surgery” was associated with an age equal to or lower than one week when treatment was started, and with an ankle plantar flexion range of motion lower than 36°.ConclusionsThe beginning of this conservative treatment in the first week of life and having a plantar flexion of the ankle lower than 36° were related to the success of the treatment without surgery.

Low-Intensity Resistance Exercise Based on Myofascial Chains Alters the Lower-Limb Tension and Improves Health Status in Female Individuals With Knee Osteoarthritis.

Low-intensity resistance exercise therapy (LIRET) based on myofascial chains, applied to both affected and nonlocal joints, is an effective method for knee osteoarthritis (OA) rehabilitation. This study applied LIRET in a comparison of prevalues and postvalues of lower-limb tension in female patients with knee OA and asymptomatic participants. Twenty-four female participants with knee OA and 20 asymptomatic women took part in a 3-month long application of LIRET. Participants' ankle passive torque and ankle range of motion in the sagittal plane were assessed with an isokinetic dynamometer. The collected values were used to estimate the sagittal-plane lower-limb tension. Compared with the asymptomatic group, participants with knee OA presented decreased maximum ankle dorsiflexion (P < .001), decreased ankle plantar flexion range (P = .023), ankle resting position more inclined to dorsiflexion (P = .017), increased ankle dorsiflexion stiffness (P = .005), and lower ankle plantar flexion stiffness (P = .034). After exercise intervention, the knee OA group self-reported less knee pain (P < .001), improved physical function (P < .001), increased maximum dorsiflexion (P = .021), and increased plantar flexion range (P < .001). While plantar flexion stiffness increased (P = .037), dorsiflexion stiffness decreased (P = .015) and ankle resting position moved toward dorsiflexion (P = .002). Results suggest possible decreased anterior leg tension and possible increased posterior leg tension in patients with knee OA. The results supported that knee OA patients present imbalanced myofascial tension of lower limbs. LIRET based on myofascial chains appears to decrease pain, and stiffness, and improve physical function of patients with knee OA and change their lower-limb tension.

Effect of Ergon IASTM technique on pain, strength and range of motion in plantar fasciitis patients. RCT

IntroductionPlantar fasciitis (PF) is a common foot problem caused by repetitive microtrauma or excessive overload of fascia. Instrument-assisted soft tissue mobilization (IASTM), stretching, and strengthening exercises are more helpful to reduce the pressure of fascia and improve functional activities of the patients. The objective of the study was to compare the efficacy of instrument assisted soft tissue mobilization using the Ergon technique with conservative treatment in plantar fasciitis.MethodsThis randomized control trial was conducted at the Department of Physiotherapy of the University of Lahore Teaching Hospital and Citi Hospital Lahore. After assigning, the patients were randomly allocated into treatment and conventional groups. Both groups received therapeutic ultrasound therapy, stretching strengthening exercises, cryotherapy and the experimental group received additional instrument-assisted soft tissue mobilization. Pain, strength, and range of motion were assessed at baseline, 1st, 3rd, and 5th week after treatment.Results64 participants were randomly allocated into two groups; the Ergon group (ET = 32) and the conventional group (CT = 32). The mean age in the ET group was 29.1 ± 6.0 and in the CT group was 29.5 ± 6.0 and the gender distribution of the study population was 28.1% were male and 71.9% were females. There was significant improvement (&lt;i&gt;p&lt;/i&gt; &lt; 0.05) in pain, strength, and plantarflexion range of motion among all participants in the treatment group. However, no significant improvement was noticed in the dorsiflexion range (&lt;i&gt;p&lt;/i&gt; &gt; 0.05). While within-group analysis showed improvement in the dorsiflexion range of both groups (&lt;i&gt;p&lt;/i&gt; &lt; 0.05).ConclusionsThis randomized control trial demonstrates that the inclusion of instrument-assisted soft tissue mobilization using the Ergon Technique for plantar fasciitis lasting 5 weeks is an effective treatment intervention in reducing pain and improving strength and ankle range of motion.

Comparing the effects of ankle integral and conventional physiotherapy on pain, range of motion, balance, disability, and treatment effectiveness in patients with chronic ankle instability: Randomized controlled trial

Objective To compare the effects of ankle integral and conventional physiotherapy on pain, range of motion, balance, disability, and treatment effectiveness in patients with chronic ankle instability (CAI). Design Two-arm, parallel-group, randomized, double-blind, controlled trial. Participants 60 patients with unilateral CAI. Intervention integral physiotherapy (n = 30) or conventional physiotherapy (n = 30). Outcomes Visual Analog Scale (VAS), dorsiflexion and plantarflexion range of motion, Star Excursion Balance Test (SEBT), Single Leg Hop (SLH) test, Foot and Ankle Outcome Score (FAOS), Lower Extremity Functional Score (LEFS), global rating of change, were gathered pre and post-intervention. Results The ANOVA results revealed statistically significant interaction for FAOS, and LEFS outcome measures (P < 0.05) and the mean change results showed there were a favorable clinical difference incline toward the integral group (meanintegral = 20.14 (14.95–25.37), meanConventional = 29.46 (24.09–34.83)). There were no interactions between group and time among other outcome measures (P > 0.05). The group main effect did not show any statistical significance (P > 0.05). Conclusion Hip strengthening and balance exercises added to ankle rehabilitation could be more favorable on improving the patients’ functional ability.

Mirror-Based Robotic Therapy for Ankle Recovery with a Serious Game: A Case Study with a Neurological Patient.

Neuromuscular disorders, such as foot drop, severely affect the locomotor function and walking independence after a brain injury event. Mirror-based robotic therapy (MRT) has been a promising rehabilitation strategy favouring upper limb muscle strength and motor control in the last years. However, there are still no studies validating this technique in lower limb experimental protocols. This paper presents an innovative visual and motor feedback strategy based on serious games and MRT modalities. Thus, a preliminary system validation with a healthy participant is performed. Moreover, the strategy's potential effects were investigated in a neurologic patient's short rehabilitation program. After six sessions, the results of the method favoured active ankle plantarflexion range of motion and muscle activation. Although the patient had a positive adaptation at the end of the game, it is necessary to improve the proposed strategy to enhance the robotic experience in the long term.

Effect of Mosaic Allograft Osteochondral Transplantation Combined with Corrective Osteotomy in Treating Osteochondral Lesions of the Talus on Ankle and Knee Joint Function and Lower Limb Alignment.

Objective To explore the effect of mosaic allograft osteochondral transplantation combined with corrective osteotomy in treating osteochondral lesions of the talus (OLT) on ankle and knee joint function and lower limb alignment. Methods One hundred and thirty-three OLT patients treated in our hospital between July 2015 and October 2019 were enrolled. Regarding the various surgical approaches, they were categorized into two groups, namely, A and B including 69 and 64 cases, respectively. The patients in group A were processed with mosaic allograft osteochondral transplantation combined with corrective osteotomy, and the patients in group B were processed with microfracture surgery. The Baird ankle function score and visual analog scale (VAS) were employed for evaluating the surgical efficacy and the degree of pain prior to and following surgery. The pre- and postoperative surgery-related indicators, Ankle Hindfoot Scale (AOOFAS), HSS score, lower limb alignment, and range of motion of the ankle were compared between the two groups, and changes in growth factor levels prior to and following processing were observed. Results Overall scores were better in group A than in group B (P < 0.05). The operation length was longer in group A, the amount of intraoperative blood loss was greater, and the length of hospitalization was less than in group B. The VAS score 48 hours after surgery was also lower (P < 0.05). Postoperative AOFAS scores in group A were better, and lower limb alignment was also less than in group B (P < 0.05). The postoperative HSS score did not differ significantly between the two groups (P > 0.05). The range of plantar flexion and dorsiflexion of the ankle joint was better in group A, and the levels of endothelial growth factor (VEGF), platelet-derived growth factor (PDG), and transforming growth factor β1 (TGF-β1) were lower than those in group B (P < 0.05). The occurrence of postoperative problems did not differ between the groups (P > 0.05). Conclusion Mosaic allograft osteochondral transplantation combined with corrective osteotomy has a high effective rate in the treatment of OLT, which can promote the healing of articular cartilage and the recovery of ankle joint functions, improve the range of motions of the ankle, and improve the lower limb alignment.

The Reliability and Validity of a Novel Ankle Isometric Plantar Flexion Strength Test.

Strengthening of ankle plantar flexor muscles is one of the important components in the rehabilitation of many lower limb injuries and disorders. However, there are few simple methods to evaluate ankle plantar flexor strength in clinical situations without using equipment. The purpose of this study was to verify the intraexaminer and interexaminer reliability and the concurrent validity of a novel ankle isometric plantar flexion (PF) strength test (PF break test [PFBT]). Case-control study. The intraexaminer and interexaminer reliabilities of the PFBT were evaluated in 57 orthopedic patients and 30 healthy adults. The range of motion of the ankle joint and the number of heel raises were compared between positive and negative PFBT cases. Then, isometric ankle PF torque (ankle PF of 0°, 15°, and 30°) was compared in knee extension and in the 50° flexion position between positive and negative PFBT cases in 30 healthy adults. The intraexaminer reliability (κ) of the PFBT was .81 to .94, and the interexaminer reliability (κ) was .37 to .74. The PFBT positive group had a significantly smaller range of motion in the ankle joint (P < .05) and a significantly lower number of heel raises (P < .001) than the PFBT negative group in orthopedic patients, but no significant differences in healthy adults. The PFBT positive group had less ankle PF torque than the PFBT negative group at all ankle PF angles (P < .01). The isometric PF torque in the end range of ankle PF in knee extension could predict the results of the PFBT and correctly classified 90.0% of cases (P < .001). The PFBT is considered a simple and valid method to evaluate isometric ankle PF strength in the clinical setting.

Persistence of Chemotherapy-Induced Peripheral Neuropathy Despite Vincristine Reduction in Childhood B-Acute Lymphoblastic Leukemia.

Children with B-acute lymphoblastic leukemia (B-ALL) are at risk for chemotherapy-induced peripheral neuropathy (CIPN). Children's Oncology Group AALL0932 randomized reduction in vincristine and dexamethasone (every 4 weeks vs 12 weeks during maintenance in the average-risk subset of National Cancer Institute standard-B-ALL (SR AR B-ALL). We longitudinally measured CIPN, overall and by treatment group. AALL0932 standard-B-ALL patients aged 3 years and older were evaluated at T1-T4 (end consolidation, maintenance month 1, maintenance month 18, 12 months posttherapy). Physical and occupational therapists (PT/OT) measured motor CIPN (hand and ankle strength, dorsiflexion and plantarflexion range of motion), sensory CIPN (finger and toe vibration and touch), function (dexterity [Purdue Pegboard], and walking efficiency [Six-Minute Walk]). Proxy-reported function (Pediatric Outcome Data Collection Instrument) and quality of life (Pediatric Quality of Life Inventory) were assessed. Age- and sex-matched z scores and proportion impaired were measured longitudinally and compared between groups. Consent and data were obtained from 150 participants (mean age = 5.1 years [SD = 1.7], 48.7% female). Among participants with completed evaluations, 81.8% had CIPN at T1 (74.5% motor, 34.1% sensory). When examining severity of PT/OT outcomes, only handgrip strength (P < .001) and walking efficiency (P = .02) improved from T1-T4, and only dorsiflexion range of motion (46.7% vs 14.7%; P = .008) and handgrip strength (22.2% vs 37.1%; P = .03) differed in vincristine and dexamethasone every 4 weeks vs vincristine and dexamethasone 12 weeks at T4. Proxy-reported outcomes improved from T1 to T4 (P < .001), and most did not differ between groups. CIPN is prevalent early in B-ALL therapy and persists at least 12 months posttherapy. Most outcomes did not differ between treatment groups despite reduction in vincristine frequency. Children with B-ALL should be monitored for CIPN, even with reduced vincristine frequency.
