Abstract
CONTEXT Spinal cord injury (SCI) is a neurological condition that significantly impacts a person's lifestyle, health and well-being. Many individuals with SCI experience secondary musculoskeletal shoulder pain. This scoping review examines the current research on the diagnosis and management of shoulder pain in SCI. OBJECTIVE The aim of this Scoping Review was (1) to chart peer-reviewed literature regarding the diagnosis and management of shoulder pain as it relates to SCI and (2) identify gaps in this body of literature to inform future research priorities. METHODS Six electronic databases were searched from inception until April 2022. In addition, reviewers scanned the reference lists of identified articles. Articles from peer-reviewed sources that reported diagnostic or management procedures for musculoskeletal shoulder conditions within the SCI population were considered and 1679 articles were identified. Title and abstract screening, full text review, and data extraction were undertaken by two independent reviewers. RESULTS Eighty seven articles were included, covering diagnosis or management of shoulder pain in SCI. CONCLUSION Whilst the most commonly reported diagnostic procedures and management strategies reflect contemporary practice for shoulder pain, the entire body of literature demonstrates inconsistencies in methodologies. In places, the literature continues to perceive value in procedures inconsistent with best practice. These findings encourage researchers to pursue the development of robust models of care for musculoskeletal shoulder pain in SCI using a collaborative and integrated approach, combining best practice for musculoskeletal shoulder pain alongside clinical expertise in the management of SCI.

The differences in demographics, fear of falling, transfer quality and participation enfranchisement between manual and power wheelchair users with multiple sclerosis and spinal cord injury. Disabil Rehabil Assist Technol 2024; 19:1003-1008. [PMID: 36301722 DOI: 10.1080/17483107.2022.2138998] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 08/31/2022] [Accepted: 10/17/2022] [Indexed: 10/31/2022]
Abstract
PURPOSE To examine the differences in demographics, fear of falling (FOF), transfer quality and participation enfranchisement between manual and power wheelchair users with multiple sclerosis (MS) and spinal cord injury (SCI). MATERIALS AND METHODS Secondary data analysis including 126 manual or power wheelchair users with MS and SCI (median age, 53.00 years, IQR = 24.00). Demographic information including age, gender, height, weight and disability duration was collected. Body mass index (BMI) was calculated for all participants. Participation enfranchisement was examined using both subscales (Importance and Control) of the enfranchisement scale of the Community Participation Indicator (CPI). FOF was assessed using the Spinal Cord Injury-Falls Concern Scale (SCI-FCS) and transfer quality was assessed using the Transfer Assessment Instrument (TAI) 3.0 and 4.0. Mann-Whitney's U-tests or independent samples t-tests and chi-square were used to analyse the differences between continuous variables and categorical variables, respectively. RESULTS Fifty-seven percent of participants were manual wheelchair users. There were significant differences in most demographic information except for weight and disability duration. Significant differences were also found for BMI (t = 1.06, p = 0.04), CPI-Importance (U = 1282.50, p < 0.01), CPI-Control (U = 1165.50, p < 0.01) and SCI-FCS (t = 4.08, p < 0.01). Manual wheelchair users outperformed power wheelchair users in all outcomes analysed except the TAI (p = 0.18). CONCLUSIONS Power wheelchairs users presented with a higher BMI, reported lower participation enfranchisement, and reported higher levels of FOF compared to manual wheelchair users. The findings may help clinicians to develop targeted rehabilitation goals specific for power and manual wheelchair users with MS and SCI.

Abstract
Background Patients with paraplegia often experience chronic shoulder pain due to overuse. We sought to determine if these patients have an increased prevalence of perioperative complications and higher rates of re-admissions and rotator cuff re-tears relative to able-bodied controls following rotator cuff repair (RCR). Methods We queried the NRD (2011-2018) to identify all patients undergoing primary RCR (n = 34,451) and identified cohorts of matched paraplegic and non-paraplegic patients (n = 194 each). We compared demographic factors, comorbidity profiles, perioperative complication rates, length of stay, revision rates, and re-admission rates between the two groups. Results Patients with paraplegia had lower rates of chronic obstructive pulmonary disease (p = 0.02), hypertension (p = 0.007), congestive heart failure (p = 0.027), obesity (p < 0.001), and prior myocardial infarction (p = 0.01). Additionally, patients with paraplegia experienced higher rates of urinary tract infections (11.9% vs. 2.1%, p < 0.001), lower rates of acute respiratory distress syndrome (0% vs. 3.1%, p = 0.041), and had a longer length of stay (4-days vs. 1-day, p < 0.001). Revision rates were similar for the two groups. Conclusions Compared to matched controls, patients with paraplegia were found to have similar demographic characteristics, less comorbidities, similar perioperative complication rates, and similar revision rates. These findings address a gap in the literature regarding surgical management of shoulder pain in patients with paraplegia by providing a matched comparison with a large sample size.

Abstract
BACKGROUND Manual wheelchair propulsion is widely accepted to be biomechanically inefficient, with a high prevalence of shoulder pain and injuries among users. Directional control during wheelchair movement is a major, yet largely overlooked source of energy loss: changing direction or maintaining straightforward motion on tilted surfaces requires unilateral braking. This study evaluates the efficiency of a novel steering-by-leaning mechanism that guides wheelchair turning through upper body leaning. METHODS 16 full-time wheelchair users and 15 able-bodied novices each completed 12 circuits of an adapted Illinois Agility Test-course that included tilted, straight, slalom, and 180° turning sections in a prototype wheelchair at a self-selected functional speed. Trials were alternated between conventional and steering-by-leaning modes while propulsion forces were recorded via instrumented wheelchair wheels. Time to completion, travelled distance, positive/negative power, and work done, were all calculated to allow comparison of the control modes using repeated measures analysis of variance. RESULTS Substantial average energy reductions of 51% (able-bodied group) and 35% (wheelchair user group) to complete the task were observed when using the steering-by-leaning system. Simultaneously, able-bodied subjects were approximately 23% faster whereby completion times did not differ for wheelchair users. Participants in both groups wheeled some 10% further with the novel system. Differences were most pronounced during turning and on tilted surfaces where the steering-by-leaning system removed the need for braking for directional control. CONCLUSIONS Backrest-actuated steering systems on manual wheelchairs can make a meaningful contribution towards reducing shoulder usage while contributing to independent living. Optimisation of propulsion techniques could further improve functional outcomes.

Could the Improvement of Supraspinatus Muscle Activity Speed up Shoulder Pain Rehabilitation Outcomes in Wheelchair Basketball Players? INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 20:255. [PMID: 36612577 PMCID: PMC9819299 DOI: 10.3390/ijerph20010255] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 12/18/2022] [Accepted: 12/20/2022] [Indexed: 06/17/2023]
Abstract
Shoulder pain (SP) is a common clinical complaint among wheelchair basketball (WB) players, since their shoulders are exposed to intense overload and overhead movements. The supraspinatus tendon is the most exposed to WB-related injuries and it is primarily responsible for SP in WB athletes. In these cases, SP rehabilitation remains the main treatment, but there is still a lack of specific protocols which should be customized to WB players' peculiarities and to the supraspinatus muscle activity monitor, and the improvement of rehabilitation outcomes is slow. Thus, the aim of this study was to verify if the improvement of supraspinatus muscle activity, monitored in real time with surface electromyography (sEMG) during the execution of therapeutic exercises, could speed up SP rehabilitation outcomes in WB players. Thirty-three athletes were enrolled. They were divided into two groups. Both groups underwent the same shoulder rehabilitation program, but only the Exercise Plus sEMG Biofeedback Group executed therapeutic exercises while the activity of the supraspinatus muscles was monitored using sEMG. Participants were evaluated at enrollment (T0), at the end of 4 weeks of the rehabilitation program (T1), and 8 weeks after T1 (T2), using the following outcome measures: supraspinatus muscle activity as root mean square (RMS), Wheelchair User's Shoulder Pain Index (WUSPI), shoulder abduction, and external rotation range of motion (ROM). The Exercise Plus sEMG Biofeedback Group improved more and faster for all the outcomes compared to the Exercise Group. The monitoring and improvement of supraspinatus muscle activity seems to be an effective way to speed up SP rehabilitation outcomes in WB players, since it makes the performance of therapeutic exercise more precise and finalized, obtaining better and faster results in terms of recovery of shoulder function.

Abstract
Wheelchair basketball (WB) involves sports gestures that expose the shoulder to high biomechanical stress and frequently lead to shoulder pain (SP). Due to their physical peculiarities and sporting performance, these athletes require specific rehabilitation programs that are as fast, personalized and effective as possible. However, there are few studies specifically dedicated to these purposes. Surface electromyography (sEMG) seems a promising tool for better customization and achieving more targeted rehabilitation results. The aim of this study was to evaluate the usefulness of sEMG to monitor SP rehabilitation outcomes in WB players. Thirty-three athletes were enrolled in this non-randomized clinical study and divided into two groups. Both groups underwent a shoulder rehabilitation protocol, but only the experimental group was monitored in real time with sEMG on the shoulders. At enrollment (T0), at the end of 4 weeks of the rehabilitation program (T1), and 8 weeks after T1 (T2), the following outcome measures were collected: Wheelchair User’s Shoulder Pain Index (WUSPI), 20 m straight line test, shoulder abduction range of motion (ROM). There was a statistically significant difference for WUSPI and ROM scores in the comparison between groups (p < 0.001), and for all outcomes in the comparison between times and in the interaction between time and group (p < 0.001). Therefore, the experimental group showed a better improvement at all detection times compared to the control group. sEMG seems a useful tool for improving the monitoring of SP rehabilitation outcomes in WB players. This monitoring speeds up and improves the rehabilitative results, limiting the risk of sport abandonment and increasing the possibility for people with disabilities to quickly return to practice physical activity.

Abstract
Pathogenic variants in the ABCD1 gene on the X chromosome may result in widely heterogenous phenotypes, including adrenomyeloneuropathy (AMN). Affected males typically present in their third or fourth decade of life with progressive lower limb weakness and spasticity, and may develop signs and symptoms of adrenal insufficiency and/or cerebral demyelination. Heterozygous females may be asymptomatic, but may develop a later-onset and more slowly progressive spastic paraparesis. In this review, we describe the clinical presentation of AMN, as well as its diagnosis and management. The role of rehabilitative therapies and options for management of spasticity are highlighted.

Aissaoui R, Gagnon D. Effect of Haptic Training During Manual Wheelchair Propulsion on Shoulder Joint Reaction Moments. FRONTIERS IN REHABILITATION SCIENCES 2022; 3:827534.

Abstract
Background Manual wheelchair propulsion remains a very ineffective means of locomotion in terms of energy cost and mechanical efficiency, as more than half of the forces applied to the pushrim do not contribute to move the wheelchair forward. Manual wheelchair propulsion training using the haptic biofeedback has shown an increase in mechanical efficiency at the handrim level. However, no information is available about the impact of this training on the load at the shoulders. We hypothesized that increasing propulsion mechanical efficiency by 10% during propulsion would not yield clinically significant augmentation of the load sustained at the shoulders. Methods Eighteen long-term manual wheelchair users with a spinal cord injury propelled a manual wheelchair over a wheelchair simulator offering the haptic biofeedback. Participants were asked to propel without the Haptic Biofeedback (HB) and, thereafter, they were subjected to five training blocks BL1–BL5 of 3 min in a random order with the haptic biofeedback targeting a 10% increase in force effectiveness. The training blocs such as BL1, BL2 BL3, BL4, and BL5 correspond, respectively, to a resistant moment of 5, 10, 15, 20, and 25%. Pushrim kinetics, shoulder joint moments, and forces during the propulsive cycle of wheelchair propulsion were assessed for each condition. Results The tangential force component increases significantly by 74 and 87%, whereas value for the mechanical effective force increases by 9% between the pretraining and training blocks BL3. The haptic biofeedback resulted in a significant increase of the shoulder moments with 1–7 Nm. Conclusion Increases in shoulder loads were found for the corresponding training blocks but even though the percentage of the increase seems high, the amplitude of the joint moment remains under the values of wheelchair propulsion found in the literature. The use of the HB simulator is considered here as a safe approach to increase mechanical effectiveness. However, the longitudinal impact of this enhancement remains unknown for the impact on the shoulder joint. Future studies will be focused on this impact in terms of shoulder risk injury during manual wheelchair propulsion.

Relationship Between Shoulder Pain and Joint Reaction Forces and Muscle Moments During 2 Speeds of Wheelchair Propulsion. J Appl Biomech 2022; 38:404-411. [DOI: 10.1123/jab.2022-0066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 07/31/2022] [Accepted: 08/29/2022] [Indexed: 11/15/2022]
Abstract
The purpose of this study was to determine shoulder joint reaction forces and muscle moments during 2 speeds (1.3 and 2.2 m/s) of wheelchair propulsion and to investigate the relationship between joints reaction forces, muscle moments, and shoulder pain. The measurements were obtained from 20 manual wheelchair users. A JR3 6-channel load sensor (±1% error) and a Qualisys system were used to record 3-dimensional pushrim kinetics and kinematics. A 3-dimensional inverse dynamic model was generated to compute joint kinetics. The results demonstrated significant differences in shoulder joint forces and moments (P < .01) between the 2 speeds of wheelchair propulsion. The greatest peak shoulder joint forces during the drive phase were anterior directed (Fy, 184.69 N), and the greatest joint moment was the shoulder flexion direction (flexion moment, 35.79 N·m) at 2.2 m/s. All the shoulder joint reaction forces and flexion moment were significantly (P < .05) related to shoulder pain index. The forces combined in superior and anterior direction found at the shoulder joint may contribute to the compression of subacromial structure and predispose manual wheelchair users to potential rotator cuff impingement syndrome.

Abstract
STUDY DESIGN Systematic review and meta-analysis OBJECTIVES: The objective was to summarise prior research regarding the efficacy of active physiotherapy interventions and prevention strategies on shoulder pain, decreased physical function and quality of life in people with a spinal cord injury (SCI). METHODS A systematic literature search was conducted in CENTRAL, EMBASE (via Ovid), CINAHL and MEDLINE (via Ovid). Randomised controlled trials investigating effects of active physiotherapy interventions on shoulder pain, physical function and quality of life were included. Further, prospective cohort studies investigating effects of active physiotherapy interventions in prevention of shoulder pain and reduced physical function were included. Mean difference (MD) for pain (15 items on a 0-10 scale) and standardised mean difference (SMD) for physical function were summarised in a random effects meta-analysis. RESULTS Four studies on treatment (totalling 167 participants), and no studies on prevention were included. Significant and clinically meaningful improvements on shoulder pain (MD 19.06, 95% CI 5.72-32.40; I2 = 65%) (scale 0-150) and physical function (SMD 0.61, 95% CI 0.27-0.94; I2 = 0%) were found for active physiotherapy interventions. Only one study included quality of life, making meta-analysis inappropriate. CONCLUSIONS Evidence from a sparse number of studies supports active physiotherapy interventions to decrease shoulder pain and increase physical function in people with SCI who use a manual wheelchair. No studies met the criteria for prevention, highlighting a lack of research investigating prevention of shoulder pain and decreased physical function and quality of life.

Abstract
The purpose of this study was to investigate the longitudinal association between within-subject changes in shoulder pain and alterations in wheelchair propulsion biomechanics in manual wheelchair users. Eighteen (age 33 ± 11 years) manual wheelchair users propelled their own daily living wheelchair at 1.11 m.s-1 for three minutes on a dual-roller ergometer during two laboratory visits (T1 and T2) between 4 and 6 months apart. Shoulder pain was assessed using the Performance Corrected Wheelchair User's Shoulder Pain Index (PC-WUSPI). Between visits mean PC-WUSPI scores increased by 5.4 points and varied from - 13.5 to + 20.9 points. Of the eighteen participants, nine (50%) experienced increased shoulder pain, seven (39%) no change in pain, and two (11%) decreased pain. Increasing shoulder pain severity correlated with increased contact angle (r = 0.59, P = 0.010), thorax range of motion (r = 0.60, P = 0.009) and kinetic and kinematic variability. Additionally, increasing shoulder pain was associated with reductions in peak torque (r = -0.56, P = 0.016), peak glenohumeral abduction (r = -0.69, P = 0.002), peak scapular downward rotation (r = -0.68, P = 0.002), and range of motion in glenohumeral flexion/extension and scapular angles. Group comparisons revealed that these biomechanical alterations were exhibited by individuals who experienced increased shoulder pain, whereas, propulsion biomechanics of those with no change/decreased pain remained unaltered. These findings indicate that wheelchair users exhibit a protective short-term wheelchair propulsion biomechanical response to increases in shoulder pain which may temporarily help maintain functional independence.
