Comparison of hip abductors’ strength and 2D frontal plane projection angle during two functional tests, in females with and without patellofemoral pain

IntroductionHip abductors eccentrically maintain leg alignment during weight-bearing exercises. Hip abductors' weakness may be a significant aspect to take into account in the conservative management of Patellofemoral Pain (PFP). The aim of the study was to compare hip abductors’ eccentric strength and hip kinematics during two functional tests, in female subjects with PFP. MethodIn a cross-sectional study using convenience sampling, isokinetic Isokinetic unilateral eccentric hip abductors’ mean peak moment (MPM) at 60°/sec and Frontal Plane Projection Angle (FPPA) during Single-Leg Squat (SLS) and Single-Leg Landing (SLL) tests, were assessed in 17 asymptomatic individuals and 19 PFP patients. ResultsThe FPPA during SLL (p = 0.771) and SLS (p = 0.587), as well as the isokinetic values of the eccentric adductors' MPM at 60°/sec (p = 0.769), did not differ between the groups. The isokinetic values and the SLL (r = −0.009 to p = 0.970) and SLS (r = −0.002 to p = 0.993) in the PFP group and the control group (SLS r = 0.160 to p = 0.540) did not show any statistically significant relationships. ConclusionPFP and asymmetry in hip abduction strength are not substantially correlated. It is necessary to conduct more research to comprehend how these impairments interact and to find out if there are patient subgroups with PFP.

Virtual reality training versus conventional rehabilitation for chronic neck pain: A systematic review and meta-analysis.

To identify, critically appraise, and quantitatively synthesize current randomized controlled trials to compare the effects of virtual reality and dose-matched conventional exercises in patients with chronic neck pain. PubMed, Embase, CINAHL, PsycINFO, and Scopus were searched for studies published prior to April 15, 2023. The search strategies combined controlled vocabularies and title/abstract keywords on search themes of virtual reality and neck pain. A systematic review and meta-analysis of randomized controlled trials was conducted. Two independent reviewers conducted study selection, data extraction, and quality assessment. Methodological quality was assessed using the Physiotherapy Evidence Database scale. Meta-analyses were performed using random-effects models. Six randomized controlled trials including 243 participants with chronic neck pain met the inclusion criteria. Four studies were evaluated as good quality and two as fair. Pooled analysis revealed that virtual reality demonstrated significantly better improvements in the Neck Disability Index in both the short term (mean difference [MD] = -2.16; 95% confidence interval [CI]: -3.50 to -0.82) and long term (MD = -2.95; 95% CI: -4.93 to -0.97), and pain intensity in the short term (MD = -0.94, 95% CI: -1.31 to -0.58). No significant between-group differences were found in pain in the long term and kinesiophobia. Virtual reality is a promising intervention to address disability and pain in patients with chronic neck pain. This review supports the clinical significance of augmenting conventional exercise with virtual reality as part of conservative management of chronic neck pain.

SPiRIT study protocol (Shoulder Pain: Randomised trial of Injectable Treatments): a randomised feasibility and pilot study of autologous protein solution (APS) vs corticosteroids for treating subacromial shoulder pain

BackgroundThe management of subacromial shoulder pain represents a significant challenge and is typically managed through either physiotherapy, joint injection or surgical intervention. Recent surgical trials have questioned the efficacy and there is a need to improve the evidence base for the non-surgical management of this condition.The study aims to provide evidence of the feasibility of conducting a randomised controlled trial to compare the efficacy of autologous protein solution (APS) against the current standard of care, corticosteroid injection (CSI) for subacromial shoulder pain. Autologous protein solution (APS) is a blood-derived biological injection which has been shown to have anti-inflammatory effects.MethodsA parallel-group two-arm randomised control trial will be conducted, comparing APS and CSI for shoulder pain. Fifty patients will be recruited. Feasibility will be assessed by examination of the conversion rate of eligible participants to the total number of participants recruited, whether it is possible to collect the appropriate outcome measures and the levels of retention/data compliance at follow-up dates.DiscussionCSI is the mainstay of conservative management of subacromial shoulder pain. Trials and systematic reviews have reported differing conclusions, but the consensus view is that any benefits seen from CSI use are most likely to be short-term and there remains a significant number of patients who go on to have surgical intervention despite CSI.Biological injections, such as APS are being increasingly used, in the anticipation they may offer improved longer lasting outcomes for shoulder pain. However, the evidence to demonstrate the comparative efficacy of CSI versus APS does not currently exist. If feasible, a fully powered study will offer clarity to the treatment pathway of thousands of patients each year with subacromial pain.Trial registrationThe study is funded by the National Institute for Health Research–Research for Patient Benefit, NIHR 201473, Trial Registration Number (ISRCTN12536844: SPiRIT. Shoulder pain: randomised trial of injectable treatments–date of Registration 15/9/2021). Protocol Version V1.0_30Jul2021. IRAS Project ID: 294,982.

The Use of Peripheral Nerve Block and Intra-articular Steroid Injection for Pain Management in an Adolescent with Hutchinson-Gilford Progeria Syndrome: A Case Report.

Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare genetic disorder causing accelerated aging and age-related pathologies. Weighing benefits and risks on doing surgical versus conservative pain management require multidisciplinary planning and consideration in HGPS patients. This presents a case of a 15-year-old patient with HGPS with severe pain from bilateral hip dislocation managed with peripheral nerve block and steroid injection. This afforded her immediate pain relief allowing her to undergo physical rehabilitation comfortably.

Whole-Body Electrostatic Pain Treatment in Adults with Chronic Pain: A Prospective Multicentric Observational Clinical Trial.

In the treatment of patients with chronic pain, whole-body electrostatic therapy using the Elosan Cabin C1 has been proposed as an adjunctive therapy. So far, data on the use of this cabin are limited. Promising results with a significant reduction in pain scores have been obtained in a small group of patients. However, treatment with Elosan Cabin C1 has not been the subject of evaluation in a larger patient population. The aim of this study was to investigate the efficacy and adverse effects of electrostatic treatment in such a population. Prospective, multi-center, observational clinical trial conducted in daily practice in a large adult ambulatory population with chronic pain. Each patient received eight weekly Elosan C1 treatment sessions for up to 9weeks. Treatment was added to an established conservative pain management. Pain scores (visual analog scale (VAS) 0-100, primary outcome) and sleep quality (seven-point Likert scale, secondary outcome) were assessed before, during, and at the end of the treatment period; quality of life (SF-12: Physical Component Summary = PCS, Mental Component Summary = MCS; secondary outcome) was assessed before and at the end of the treatment period. Subgroup analyses were performed for sex, age, duration of pain, initial pain location, pain entity, and pain medication at the start of treatment. A total of 192 patients were enrolled, 143 patients (74.5%) had a complete set of 8 treatment sessions. A reduction in pain scores from 68 ± 14 points to 47 ± 22 points was observed (p < 0.001), 65% of patients (responders) had a reduction of > 15 points. Female patients had a significantly better response than male patients with a higher number of responders (76% vs. 38%; p < 0.001). Patients with a pain history < 1year had a significantly better response than patients with a pain history > 1year. The Physical Component Summary (PCS) increased from 36 ± 11 to 41 ± 11 (+ 18%, p < 0.001) and the Mental Component Summary (MCS) from 41 ± 7 to 43 ± 7 (+ 6%, p = 0.3). Overall sleep quality improved significantly from 4.6 ± 1.7 to 3.73 ± 1.7 points (p < 0.001), with a higher proportion of responders in the female group (37 vs. 18%; p < 0.034). No serious adverse events were observed during treatment. Electrostatic therapy with Elosan Cabin C1 may be a useful and effective adjunct therapy for patients with chronic pain. The results suggest that female patients and those with a recent history of pain experience the greatest benefit. NCT04818294 (clinicaltrials.gov).

Does an alternative breast support garment provide symptomatic relief for larger breasted women with chronic non-specific back pain?

Nonsurgical guidelines recommend implementing a correctly fitted bra when managing back pain among larger breasted women. Achieving this is challenging with current bra solutions, sizing principles, and fitting approaches. Persistent wearing of an ill-fitting bra can cause negative health implications, including non-specific back pain. This study investigated immediate and short-term biomechanical and pain responses to changing breast support garment among larger breasted women with non-specific back pain. Participants (n = 24) performed a standing task, drop jumps, and seated typing tasks while bra and spinal kinematic data were recorded. Five breast support conditions were assessed: participants' usual bra (control), a professionally fitted bra in the immediate term (standard) and after 4 weeks wear (standard28), and a bra with an alternative design, measurement, and fitting approach in both the immediate term (alternative) and after 4 weeks wear (alternative28). A bra fit assessment and clinical pain/disability questionnaires were included. All participants failed the bra fit assessment in the control bra, compared with 87.5% (n = 21) in the standard and 4.2% (n = 1) in the alternative bras. The standard28 and alternative28 bras provided symptomatic relief, with the alternative28 bra improving a greater number of outcome measures. Reduced nipple-sternal-notch distance was observed only in the alternative28 bra condition. Symptomatic relief may be associated with the resting position of the breast tissue on the anterior chest wall. The alternative bra may provide potential clinical benefit if implemented as part of a nonsurgical or conservative pain management strategy. Alternative breast support garments should be considered to provide solutions to the problems associated with traditional bras.

The Impact of the Addition of a Physical Therapy Assistant to the Treatment Team for Management of Neck Pain: A Retrospective Analysis of Outpatient Physical Therapy Clinics.

Introduction The impact of physical therapy assistants (PTAs) on patient outcomes, mostly in the acute and subacute setting, is well known in the literature. However, no study to date has examined the impact of using PTAs as part of a treatment team in the outpatient setting for common musculoskeletal conditions. The purpose of this study is to determine if physical therapy team composition, either physical therapists (PTs) only or a team consisting of PTs and PTAs, has a significant impact on patient outcomes in adult patients with musculoskeletal neck pain to help investigate an ideal practice pattern for outpatient physical therapy. Methods This is a retrospective cohort study analyzing the impact of physical therapy treatment team composition (PTs only, or team consisting of PTs and PTAs) on pain, active range-of-motion (AROM), and disability outcomes via the Neck Disability Index (NDI) in the conservative treatment of neck pain. All patients were treated with usual physical therapy care. Inclusion criteria involved patients with a diagnosis of neck pain (M48.2), older than 18 years old, a physical therapy evaluation procedure code (97161, 97162, 97163), and at least two visits per bout of physical therapy. Primary outcome measures were pain, bilateral rotation AROM, disability, and number of visits. Results Included patients (n=195) had an average age of 60.8 years ± 16.1 years with an average number of total physical therapy visits of 7.4 visits ± 4.3 visits (range, 2 visits - 22 visits) with 120 patients (61.5%) treated by a PT only (PT-only group) and 75 patients (38.5%) treated by a team consisting of a PT and a PTA (PTA group). The PT-only group had significantly fewer visits than the PTA group (p<0.001). The PT-only group had a pain improvement of 2.1 points ± 2.3 points whereas the PTA group had a pain improvement of 2.2 points ± 2.4 points with no significant difference between the two groups (p=0.573). The PT-only group (n=46 patients) had an average rotation AROM improvement of 20.0 ± 17.4 degrees whereas the PTA group (n=40 patients) had an average rotation AROM improvement of 16.8 degrees ± 23.0 degrees with no significant difference between the level of rotation AROM improvement between the two groups (p=0.408). Furthermore, there was also no significant difference in the amount of NDI improvement seen in both groups (p=0.594). Conclusion There was no significant difference in patient outcomes for pain, AROM, and disability when PTAs were added to the physical therapy treatment team in the conservative management of neck pain in the outpatient setting. However, patients treated with a treatment team consisting of PTAs had significantly more visits, despite no significant change in outcomes. Randomized controlled trials are needed as the reasons for these findings can be many and require further research.

The Effects of Opioid Dependency Use on Postoperative Spinal Surgery Outcomes: A Review of the Available Literature.

There is a lack of evidence to support the effectiveness of long-term opioid therapy in patients with chronic, noncancer pain. Despite these findings, opioids continue to be the most commonly prescribed drug to treat chronic back pain and many patients undergoing spinal surgery have trialed opioids before surgery for conservative pain management. Unfortunately, preoperative opioid use has been shown repeatedly in the literature to negatively affect spinal surgery outcomes. In this review article, we identify and summarize the main postoperative associations with preoperative opioid use that have been found in previously published studies by searching on PubMed, Google Scholar, Medline, and ScienceDirect; using keywords: Opioid dependency, postoperative, spinal surgery, specifically (1) increased postoperative chronic opioid use (24 studies); (2) decreased return to work (RTW) rates (8 studies); (3) increased length of hospital stay (LOS) (9 studies); and (4) increased healthcare costs (8 studies). The conclusions from these studies highlight the importance of recognizing patients on opioids preoperatively to effectively risk stratify and identify those who will benefit most from multidisciplinary counseling and guidance.

Expanding endoscopic boundaries: Endoscopic resection of large appendiceal orifice polyps with endoscopic mucosal resection and endoscopic submucosal dissection

Large appendiceal orifice polyps are traditionally treated surgically. Recently, endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) have been utilized as alternative resection techniques. To evaluate the efficacy and safety of endoscopic resection techniques for the management of large appendiceal orifice polyps. This was a retrospective observational study conducted to assess the feasibility and safety of EMR and ESD for large appendiceal orifice polyps. This project was approved by the Baylor College of Medicine Institutional Review Board. Patients who underwent endoscopic resection of appendiceal orifice polyps ≥ 1 cm from 2015 to 2022 at a tertiary referral endoscopy center in the United States were enrolled. The main outcomes of this study included en bloc resection, R0 resection, post resection adverse events, and polyp recurrence. A total of 19 patients were identified. Most patients were female (53%) and Caucasian (95%). The mean age was 63.3 ± 10.8 years, and the average body mass index was 28.8 ± 6.4. The mean polyp size was 25.5 ± 14.2 mm. 74% of polyps were localized to the appendix (at or inside the appendiceal orifice) and the remaining extended into the cecum. 68% of polyps occupied ≥ 50% of the appendiceal orifice circumference. The mean procedure duration was 61.6 ± 37.9 minutes. Polyps were resected via endoscopic mucosal resection, endoscopic submucosal dissection, and hybrid procedures in 5, 6, and 8 patients, respectively. Final pathology was remarkable for tubular adenoma (n = 10) [one with high grade dysplasia], sessile serrated adenoma (n = 7), and tubulovillous adenoma (n = 2) [two with high grade dysplasia]. En bloc resection was achieved in 84% with an 88% R0 resection rate. Despite the large polyp sizes and challenging procedures, 89% (n = 17) of patients were discharged on the same day as their procedure. Two patients were admitted for post-procedure observation for conservative pain management. Eight patients underwent repeat colonoscopy without evidence of residual or recurrent adenomatous polyps. Our study highlights how endoscopic mucosal resection, endoscopic submucosal dissection, and hybrid procedures are all appropriate techniques with minimal adverse effects, further validating the utility of endoscopic procedures in the management of large appendiceal polyps.

DETECTING LOW BACK PHYSIOTHERAPY EXERCISES AND POSTURES WITH INERTIAL SENSORS AND MACHINE LEARNING

Physiotherapy is a critical element in successful conservative management of low back pain (LBP). The aim of this study was to develop and evaluate a system with wearable inertial sensors to objectively detect sitting postures and performance of unsupervised exercises containing movement in multiple planes (flexion, extension, rotation).A set of 8 inertial sensors were placed on 19 healthy adult subjects. Data was acquired as they performed 7 McKenzie low-back exercises and 3 sitting posture positions. This data was used to train two models (Random Forest (RF) and XGBoost (XGB)) using engineered time series features. In addition, a convolutional neural network (CNN) was trained directly on the time series data. A feature importance analysis was performed to identify sensor locations and channels that contributed most to the models. Finally, a subset of sensor locations and channels was included in a hyperparameter grid search to identify the optimal sensor configuration and the best performing algorithm(s) for exercise classification. Models were evaluated using F1-score in a 10-fold cross validation approach.The optimal hardware configuration was identified as a 3-sensor setup using lower back, left thigh, and right ankle sensors with acceleration, gyroscope, and magnetometer channels. The XBG model achieved the highest exercise (F1=0.94±0.03) and posture (F1=0.90±0.11) classification scores. The CNN achieved similar results with the same sensor locations, using only the accelerometer and gyroscope channels for exercise classification (F1=0.94±0.02) and the accelerometer channel alone for posture classification (F1=0.91±0.03).This study demonstrates the potential of a 3-sensor lower body wearable solution (e.g. smart pants) that can identify proper sitting postures and exercises in multiple planes, suitable for low back pain. This technology has the potential to improve the effectiveness of LBP rehabilitation by facilitating quantitative feedback, early problem diagnosis, and possible remote monitoring.

Substantiating the Therapeutic Effects of Simultaneous Heat Massage Combined with Conventional Physical Therapy for Treatment of Lower Back Pain: A Randomized Controlled Feasibility Trial

There are various therapeutic options for the conservative management of lower back pain (LBP). A combination of two or more treatment options may be more effective in the clinical management of non-specific LBP. In this study, we compared the effects of simultaneous heat massage with conventional physical therapy in patients with subacute LBP. A single-center randomized controlled trial in which 40 participants with LBP were allocated to one of two groups: a heat massage group (HMG) and physical therapy group (PTG). The HMG received simultaneous heat massage therapy using a mechanical device (CGM MB-1401, Ceragem, Republic of Korea). The PTG received conventional physical therapy. Both groups received 40 min of therapy once daily, five times a week, for a total of four weeks. Changes in serum cortisol, epinephrine (EP), and norepinephrine (NE) were assessed. The outcomes were measured using the pain numeric rating scale (PNRS), the Oswestry disability index (ODI), the Roland-Morris disability questionnaire (RMDQ), the short-form McGill pain questionnaire (SF-MPQ), the multidimensional fatigue inventory (MFI-20), the Beck depression inventory (BDI), surface EMG (sEMG), and sympathetic skin response (SSR) at baseline (PRE), at 2 (2 W) and 4 weeks (4 W) following the intervention. The serum EP and NE levels in the HMG decreased after treatment. The PNRS, ODI, RMDQ, and SF-MPQ scores improved without significance in both groups. The BDI score showed improvement in the HMG before the PTG. The MFI-20 score improved in both groups, but the results were better in the HMG than in the PTG at 4 W. All the activities of sEMG were significantly decreased in both groups. However, the improvement of the %MVIC in the HMG was better than that in the PTG at 4 W. The SSR latency on sEMG decreased while the amplitude increased in the HMG at 2 W and 4 W, respectively. Following 4 weeks of combined therapies, heat massage was not superior to conventional physical therapy alone. Both treatments were shown to be effective in improving LBP and pain-related disability. However, heat massage was shown to have a better effect on the control of autonomic nerve function and underlying moods.

The Durability and Efficacy of Cryopreserved Human Umbilical Cord Tissue Allograft for the Supplementation of Cartilage Defects Associated with the Sacroiliac Joint: A Case Series

This Institutional Review Board (IRB)-approved retrospective observational protocol aims to report the safety and efficacy of birth tissue allografts applied in 38 patients with treatment-resistant sacroiliac (SI) joint pain. The research methodology consisted of an observational recording of the Numeric Pain Rating Scale (NPRS) and the Western Ontario and McMaster Universities Arthritis Index (WOMAC), which measure pain, stiffness, and physical function. No adverse events or adverse reactions were observed in the 38 patients. Statistically significant improvements in NPRS and WOMAC scores of the affected SI joint were reported after 90 days. The observational data suggests that Wharton’s jelly allograft applications are safe, minimally invasive, and efficacious. They may present an alternative to surgery for patients who fail conservative and procedural management of pain originating from chondral cartilage degeneration of the SI joint.

Utilization of Clinical Practice Guideline Interventions in the Conservative Management of Mechanical Neck Pain: A Retrospective Analysis.

Neck pain is a common musculoskeletal condition frequently treated by physical therapists. The American Physical Therapy Association (APTA) published a clinical practice guideline (CPG) in 2008 with a revision in 2017 to improve the diagnosis and treatment of neck pain. One subset of neck pain in the CPG is "Neck Pain with Mobility Deficits," also called mechanical neck pain. Little data exists on the adherence of physical therapists to the CPG-recommended treatments for neck pain as well as the outcomes associated with the utilization of the CPG. The purpose of this study is to examine both CPG treatment adherence and associated outcomes in patients treated for mechanical neck pain by physical therapists in the outpatient setting. Retrospective chart review of patients (n=224) who received physical therapy for neck pain between 2018 and 2022. Data ranges were chosen due to the publication of the CPG revision in 2017. Six interventions for mechanical neck pain from the CPG were examined: thoracic manipulation, cervical mobilization, transcutaneous electrical stimulation (TENS), dry needling, advice to stay active, and scapular resistance exercises. The exclusion criteria were a history of cervical spine surgery. Other data collected included age, sex, characteristics of the evaluating physical therapist, and the number of visits. For CPG treatment adherence, 4.5% of patients received thoracic manipulation, 47.8% of patients received cervical mobilization, 12.5% of patients received TENS, 22.8% of patients received dry needling, 99.1% of patients received advice to stay active, and 89.3% of patients received scapular resistance exercises. There was no significant improvement in pain, range of motion (ROM), and function based on a number of CPG interventions used during the bout of physical therapy (p=0.17to p=0.74). Patients who were evaluated by a physical therapist who was an Orthopedic Certified Specialist (OCS) were more likely to receive more interventions recommended by the CPG (p<0.01). CPG-recommended treatments are used with varying frequency by physical therapists when treating mechanical neck pain. Thoracic manipulation is rarely used while scapular resistance exercises are frequently used. There was no significant improvement in pain, ROM, or function based on the number of CPG-recommended treatments used during the bout of physical therapy.

Conservative Management of Inguinal Hernia: A Case Report

BACKGROUND: Few articles explore effectiveness of physical therapy in delaying surgical intervention for patients with inguinal hernia pain. As such, there is limited evidence guiding effective treatment approaches. A focus on retraining the deep stabilizing core musculature was successful in improving pain and function in a patient with an inguinal hernia in this case report. CASE PRESENTATION: The patient presented with moderate pain, utilization of a hernia belt for all functional tasks, and decreased overall functional ability. The patient had difficulty conducting his exercise regimen and tasks around his horse ranch. OUTCOME AND FOLLOW-UP: At discharge, the patient was able to lift 25 lbs, had no pain, utilized his hernia belt only when lifting over 25 lbs, and increased his score on the Lower Extremity Functional Scale by 16 points. 6 DISCUSSION: This case demonstrates the role physical therapy plays in conservative management of inguinal hernia pain and the associated loss of function with this diagnosis.

Laparoscopic Single Site Techniques in Management of Fibroid Pain during Pregnancy

<h3>Study Objective</h3> To demonstrate tips and tricks for the successful use of single site laparoscopic surgery for myomectomy during pregnancy. <h3>Design</h3> Stepwise demonstration with narrated video footage. <h3>Setting</h3> An academic tertiary care hospital. <h3>Patients or Participants</h3> Our patient is a 39-year-old G1P0 with a symptomatic 12cm degenerating pedunculated fibroid refractory to conservative pain management. <h3>Interventions</h3> Recent literature has indicated that the majority of laparotomic myomectomies performed during pregnancy showed overall positive pregnancy outcomes and low complications. This indicates that myomectomy in pregnancy is safe and can be utilized in cases unresponsive to conservative management. However, cases in literature discussing the single-site techniques for laparoscopic myomectomy during pregnancy has been sparse. Utilizing laparoscopy in myomectomy during pregnancy, permits decreased postoperative pain, quicker recovery, and lowered risk of post-operative complications. Single site laparoscopic surgery also aids in improved patient cosmesis and can be utilized for the fibroid removal. Literature has demonstrated that laparoscopic single site is safe and feasible during all stages of pregnancy. Nevertheless, this approach may be challenging for unexperienced surgeons due to the lack of triangulation and crowding of instruments in single site laparotomy. Tips and Tricks: 1. Utilizing the open-Hasson-technique 2. Placing a suture in the fibroid stalk 3. Surgeon possessing expertise in single site surgery 4. Minimizing manipulation of the uterus 5. V-loc sutures 6. Placement of a 5 mm accessory port 7. Using gentle traction 8. Leaving a stump of more than 1 cm. <h3>Measurements and Main Results</h3> The estimated blood loss was 50cc and the total operative time was 123 minutes. She had an unremarkable postoperative course, no medications were needed for pain management, and was discharged home on post-operative day 2. At 38 weeks, she successive delivered with elective cesarean delivery with no complications. <h3>Conclusion</h3> Single incision laparoscopic surgery myomectomy is a practical technique in women refractive to conservative management. When performed by an experienced surgeon the patient can benefit from faster specimen removal and recovery.

Detection of Low Back Physiotherapy Exercises With Inertial Sensors and Machine Learning: Algorithm Development and Validation.

BackgroundPhysiotherapy is a critical element in the successful conservative management of low back pain (LBP). A gold standard for quantitatively measuring physiotherapy participation is crucial to understanding physiotherapy adherence in managing recovery from LBP.ObjectiveThis study aimed to develop and evaluate a system with wearable inertial sensors to objectively detect the performance of unsupervised exercises for LBP comprising movement in multiple planes and sitting postures.MethodsA quantitative classification design was used within a machine learning framework to detect exercise performance and posture in a cohort of healthy participants. A set of 8 inertial sensors were placed on the participants, and data were acquired as they performed 7 McKenzie low back exercises and 3 sitting posture positions. Engineered time series features were extracted from the data and used to train 9 models by using a 6-fold cross-validation approach, from which the best 2 models were selected for further study. In addition, a convolutional neural network was trained directly on the time series data. A feature importance analysis was performed to identify sensor locations and channels that contributed the most to the models. Finally, a subset of sensor locations and channels was included in a hyperparameter grid search to identify the optimal sensor configuration and best performing algorithms for exercise and posture classification. The final models were evaluated using the F1 score in a 10-fold cross-validation approach.ResultsIn total, 19 healthy adults with no history of LBP each completed at least one full session of exercises and postures. Random forest and XGBoost (extreme gradient boosting) models performed the best out of the initial set of 9 engineered feature models. The optimal hardware configuration was identified as a 3-sensor setup—lower back, left thigh, and right ankle sensors with acceleration, gyroscope, and magnetometer channels. The XGBoost model achieved the highest exercise (F1 score: mean 0.94, SD 0.03) and posture (F1 score: mean 0.90, SD 0.11) classification scores. The convolutional neural network achieved similar results with the same sensor locations, using only the accelerometer and gyroscope channels for exercise classification (F1 score: mean 0.94, SD 0.02) and the accelerometer channel alone for posture classification (F1 score: mean 0.88, SD 0.07).ConclusionsThis study demonstrates the potential of a 3-sensor lower body wearable solution (eg, smart pants) that can identify exercises in multiple planes and proper sitting postures, which is suitable for the treatment of LBP. This technology has the potential to improve the effectiveness of LBP rehabilitation by facilitating quantitative feedback, early problem diagnosis, and possible remote monitoring.

Rhizotomy and endoscopic discectomy for chronic low back pain and acute radiculopathy in a stiff-person syndrome - case report

INTRODUCTION: Stiff Person Syndrome (SPS) is a rare neurological disorder, first described in 1956 by Moersch and Woltman. The clinical picture has an insidious onset of classic findings of episodic painful spasms, hyperreflexia, axial muscle stiffness, progressing slowly to the proximal limb muscles. Painful hyperlordosis due to lumbar spine stiffness is a diagnostic characteristic of SPS. CASE REPORT: Male, 69 years old, with SPS for 40 years, referred by the neurologist to the spine surgeon because of failure to conservative management of chronic low back pain, progressively acute leg and gait impairment. Physical examination is difficult to perform in SPS because it triggers spasms. MRI presented zygoapophyseal joint, intervertebral discs and muscle degeneration, including a L4L5 cranial migrated herniated disc. Once there were no other effective ways to manage his axial and radicular pain, it was decided to perform percutaneous transforaminal endoscopic discectomy for L4L5 decompression, L3 to S1 dorsal ganglion root medial branch ablative radiofrequency rhizotomy to relieve facet pain and L2 dorsal sensory ganglion pulsed radiofrequency rhizotomy for modulation of chronic low back pain. One year postoperative follow up, the patient has showed improvement in the VAS and SF-36. CONCLUSION: Chronic pain reported by a patient must be addressed in the biological, psychological and social dimensions. Understanding the multidimensionality of the factors involved with pain allows planning less aggressive and highly efficient strategies in uncommon and off label patients, as in the case of SPS.

Critical Steps to Performing a Successful Single-site Laparoscopic Myomectomy for Large Pedunculated Myoma during Pregnancy

To demonstrate tips and tricks for the successful use of single-site laparoscopic surgery for pedunculated myomectomy during pregnancy. Stepwise demonstration with narrated video footage. An academic tertiary care hospital affiliated with Baylor College of Medicine. Our patient is a 39-year-old pregnant G1P0010 with a symptomatic 12-cm degenerating pedunculated myoma refractory to conservative pain management. Recent literature has indicated that most laparotomic myomectomies performed during pregnancy showed overall positive pregnancy outcomes and low complications. This indicates that myomectomy in pregnancy is safe and can be used in cases unresponsive to conservative management [1]. However, cases in literature discussing the single-site techniques for laparoscopic myomectomy during pregnancy have been sparse [2]. Four case series were reviewed; a total of 62 pregnant patients underwent laparoendoscopic single-site surgery without any complications [3-6]. Using laparoscopy in myomectomy compared with laparotomy during pregnancy permits decreased postoperative pain, quicker recovery, and lowered risk of postoperative complications [5,7,8]. Single-site laparoscopic surgery also aids in improved patient cosmesis and can be used for the myoma removal. Literature has demonstrated that single-site laparoscopy is safe and feasible during all stages of pregnancy [3,4]. Nevertheless, this approach may be challenging for inexperienced surgeons owing to the lack of triangulation and crowding of instruments in single-site laparoscopy [5]. At 21 weeks and 3 days pregnancy, our patient underwent single-incision laparoscopic surgery myomectomy. A 2.5-cm skin incision was made at the umbilicus to the abdominal cavity, and a GelPOINT Mini was inserted. Through the laparoscope, we can observe that a 12-cm pedunculated myoma was protruding from the right uterine fundus on a 4-cm stalk. A 0-Vicryl suture was tied around the base of the stalk. The stalk was then cauterized with bipolar energy and transected with the harmonic scalpel, completely detaching the myoma. Subsequently, an Endo Catch bag was placed around the myoma and brought up to the umbilical incision. Using a scalpel, bag-contained morcellation was completed within 22 minutes and the contents removed. As a result, the estimated blood loss was 50 cc and the total operative time was 123 minutes. The extended operating time was caused by slow movements to avoid disrupting the fetus. She had an unremarkable postoperative course, no medications were needed for pain management, and she was discharged home on postoperative day 2. At 38 weeks, she successfully delivered with elective cesarean delivery with no complications. Histopathology showed fragments of leiomyoma with diffuse necrosis. Tips and tricks: 1. Single-site entry technique uses the open Hasson technique, which reduces the risk of injury to the pregnant uterus and dilated surrounding vessels. 2. Through a 2.5-cm incision, the surgeon placed a suture in the myoma stalk because other hemostasis agents such as vasopressin are contraindicated in pregnancy. 3. Owing to difficulties related to single-site surgery, the surgeon should possess extensive expertise in single-site surgery. 4. Manipulation of the uterus should be minimized to reduce the disturbance of the pregnant uterus. 5. V-loc suture allows for faster and simplified uterine incision closure. 6. If the surgeon encounters excessive difficulty during the surgery, a 5-mm accessory port can be placed. 7. During tissue extraction, gentle traction should be used to reduce provoking the pregnant uterus. 8. When transecting the myoma stalk, it is important to leave a stump of more than 1 cm to increase suturing ease and prevent accidental suturing of the uterus. Single-incision laparoscopic surgery myomectomy for pedunculated myoma may be a practical technique in women refractive to conservative management. When performed by an experienced surgeon, the patient may benefit from faster specimen removal and recovery.

The association between early MRI and length of disability in acute lower back pain: a systematic review and narrative synthesis

BackgroundClinical guideline recommendations are against early magnetic resonance imaging (eMRI) within the first 4 to 6 weeks of conservative management of acute low back pain (LBP) without “clinical suspicion” of serious underlying conditions (red flags). There is some limited evidence that a significant proportion of patients with LBP receive eMRI non- indicated by clinical guidelines, which could be associated with increased length of disability (LOD). The aim of this systematic review was to investigate whether eMRI for acute LBP without red flags is associated with increased LOD. The LOD was defined as the number of disability days (absence from work).MethodsMedline, EMBASE, and CINAHL bibliographic databases were searched from inception until June 5, 2021. Two reviewers independently assessed the methodological quality of included studies using the Newcastle–Ottawa scale and extracted data for the review. The search identified 324 records, in which seven studies met the inclusion criteria. Three of the included studies used the same study population. Owing to between-study heterogeneity, a narrative synthesis of results was used.ResultsAll included studies were of good methodological quality and consistently reported that patients with acute LBP without red flags who received eMRI had increased LOD compared to those who did not receive eMRI. Three retrospective cohort studies reported that the eMRI groups had a higher mean LOD than the no eMRI groups ranging from 9.4 days (95% CI 8.5, 10.2) to 13.7 days (95% CI 13.0, 14.5) at the end of 1-year follow-up period. The remaining studies reported that the eMRI groups had a higher hazard ratio of work disability ranging between 1.75 (95% CI 1.23, 2.50) and 3.57 (95% CI 2.33, 5.56) as compared to the no eMRI groups.ConclusioneMRI is associated with increased LOD in patients with acute LBP without red flags. Identifying reasons for performing non-indicated eMRI and addressing them with quality improvement interventions may improve adherence to clinical guidelines and improve disability outcomes among patients with LBP.
