An exercise trial targeting posterior shoulder strength in manual wheelchair users: pilot results and lessons learned

Purpose: Because wheelchair users are unable to use standard fitness equipment such as treadmills and bikes, we developed an upper body rowing ergometer (UBRE) that can be retrofitted onto a standard stationary cycle and used to perform a rowing exercise. We validated a graded exercise testing protocol utilizing the UBRE and completed a 12-week pilot intervention to compare the training effects of the UBRE to a standard arm cycle ergometer (ACE) in manual wheelchair users. Methods: Repeat graded exercise tests were compared on the two pieces of equipment. Twenty-seven manual wheelchair users participated in the intervention. Outcomes included pre- versus post-test change in shoulder pain, strength and cardiorespiratory fitness measures. Results: Testing results obtained with the UBRE were comparable to those on the ACE. In the exercise intervention, most outcome measures did not change significantly, but individuals assigned to the UBRE were able to increase their peak exercise test power by 31?W and duration by 3.6?min. Conclusion: There is biomechanical reason to believe that rowing exercises may improve shoulder muscle balance in this population, which could reduce the risk of impingement. This may be of benefit to manual wheelchair users, who are at high risk for shoulder injury.

• Implications for Rehabilitation

• Regular exercise improves cardiorespiratory fitness and did not exacerbate shoulder pain in this group of manual wheelchair users.

• Exercises that target posterior shoulder muscle groups, such as rowing, may improve muscle balance and reduce the risk of shoulder impingement.

• Participation in exercise is hindered in this population by a high rate of secondary health conditions and difficulty accessing facilities and equipment.

     

Surgery or conservative treatment for rotator cuff tear: a meta-analysis

Purpose: Comparative evidence on treating rotator cuff tear is inconclusive. The objective of this review was to evaluate the evidence on effectiveness of tendon repair in reducing pain and improving function of the shoulder when compared with conservative treatment of symptomatic rotator cuff tear.

Method: Search on CENTRAL, MEDLINE, EMBASE, CINAHL, Web of Science and Pedro databases. Randomised controlled trials (RCT) comparing surgery and conservative treatment of rotator cuff tear. Study selection and extraction based on the Cochrane Handbook for Systematic reviews of Interventions. Random effects meta-analysis.

Results: Three identified RCTs involved 252 participants (123 cases and 129 controls). The risk of bias was considered low for all three RCTs. For Constant score, statistically insignificant effect size was 5.6 (95% CI ?0.41 to 11.62) points in 1-year follow up favouring surgery and below the level of minimal clinically important difference. The respective difference in pain reduction was ?0.93 (95% CI ?1.65 to ?0.21) cm on a 0–10 pain visual analogue scale favouring surgery. The difference was statistically significant (p?=?0.012) in 1-year follow up but below the level of minimal clinically important difference.

Conclusion: There is limited evidence that surgery is not more effective in treating rotator cuff tear than conservative treatment alone. Thus, a conservative approach is advocated as the initial treatment modality.

• Implications for Rehabilitation

• There is limited evidence that surgery is not more effective in treating rotator cuff tear than conservative treatment alone.

• There was no clinically significant difference between surgery and active physiotherapy in 1-year follow-up in improving Constant score or reducing pain caused by rotator cuff tear.

• As physiotherapy is less proneness to complications and less expensive than surgery, a conservative approach is advocated as the initial treatment modality to rotator cuff tears.

     

Exploring the ecological validity and variability of a 10-min bout of wheeling

Purpose: To determine the ecological validity of using able-bodied participants to perform a 10-min wheeling trial by (1) evaluating changes in biomechanics over the trial in manual wheelchair users and able-bodied participants naïve to wheeling and (2) describing differences in changes and variability between groups.

Materials and methods: Manual wheelchair users (n?=?7, 2–27?years’ experience) and able-bodied participants (n?=?11) wheeled for 10?min. Kinetic and temporal variables were collected and averaged over each minute, while wheeling strategy (movement pattern) was categorized at minutes 1 and 10.

Results: There was a main effect of time for push angle, and a main effect of group for average push angle, tangential force and total force. Manual wheelchair users used larger push angles and forces compared to able-bodied participants. Surprisingly, intercycle variability did not differ between groups.

Conclusion: Using able-bodied participants to represent manual wheelchair users performing a 10-min wheeling trial is not ecologically valid and caution should be used when interpreting push angle and forces applied to the pushrim. Considering that push angle was the only variable that demonstrated a main effect of time, long durations (e.g., 10?min) of wheeling may be appropriate for use in study designs acknowledging potential changes in wheeling strategy and push angle.

• Implications for Rehabilitation

• Some experienced wheelchair users and non-wheelchair users modify their movement pattern from an arc to a circular pattern within a 10-min wheeling trial.

• There are clear biomechanical differences in push angle and forces applied to the pushrim between wheelchair users with experience and able-bodied non-wheelchair users.

• Able-bodied participants who have no prior manual wheeling experience are no more variable than long-term wheelchair users.

• Variability may play an important role in wheelchair propulsion.

     

The therapeutic role of motor imagery on the functional rehabilitation of a stage II shoulder impingement syndrome

Abstract

Purpose: Motor imagery (MI) has been used as a complementary therapeutic tool for motor recovery after central nervous system disease and peripheral injuries. However, it has never been used as a preventive tool. We investigated the use of MI in the rehabilitation of stage II shoulder impingement syndrome. For the first time, MI is used before surgery. Method: Sixteen participants were randomly assigned to either a MI or control group. Shoulder functional assessment (Constant score), range of motion and pain were measured before and after intervention. Results: Higher Constant score was observed in the MI than in the control group (p?=?0.04). Participants in the MI group further displayed greater movement amplitude (extension (p?<?0.001); flexion (p?=?0.025); lateral rotation (p?<?0.001). Finally, the MI group showed greater pain decrease (p?=?0.01). Conclusion: MI intervention seems to alleviate pain and enhance mobility, this is probably due to changes in muscle control and consequently in joint amplitude. MI might contribute to postpone or even protect from passing to stage III that may require surgery.

• Implications for Rehabilitation

• Adding motor imagery training to classical physical therapy in a stage II impingement syndrome:

• Helps in alleviating pain

• Enhances shoulder mobility

• Motor imagery is a valuable technique that can be used as a preventive tool before the stage III of the impingement syndrome.

     

Effects of high- and low-energy radial shock waves therapy combined with physiotherapy in the treatment of rotator cuff tendinopathy: a retrospective study

Purpose: The aim of this study was to investigate the efficacy of high- and low-energy radial shock waves combined with physiotherapy for rotator cuff tendinopathy patients.

Methods: Data from rotator cuff tendinopathy patients received high- or low-energy radial shock waves combined with physiotherapy or physiotherapy alone were collected. The Constant and Murley score and visual analog scale score were collected to assess the effectiveness of treatment in three groups at 4, 8, 12, and 24?weeks.

Results: In total, 94 patients were involved for our retrospective study. All groups showed remarkable improvement in the visual analog scale and Constant and Murley score compared to baseline at 24?weeks. The high-energy radial shock waves group had more marked improvement in the Constant and Murley score compared to the physiotherapy group at 4 and 8?weeks and at 4?weeks when compared with low-energy group. Furthermore, high-energy radial shock waves group had superior results on the visual analog scale at 4, 8, and 12?weeks compared to low-energy and physiotherapy groups.

Conclusions: This retrospective study supported the usage of high-energy radial shock waves as a supplementary therapy over physiotherapy alone for rotator cuff tendinopathy by relieving the symptoms rapidly and maintaining symptoms at a satisfactory level for 24?weeks.

• Implications for Rehabilitation

• High-energy radial shock waves can be a supplemental therapy to physiotherapy for rotator cuff tendinopathy.

• We recommend the usage of high-energy radial shock waves during the first 5 weeks, at an interval of 7 days, of physiotherapy treatment.

• High-energy radial shock waves treatment combined with physiotherapy can benefit rotator cuff tendinopathy by relieving symptoms rapidly and maintain these improvements at a satisfactory level for quite a long time.

     

Important wheelchair skills for new manual wheelchair users: health care professional and wheelchair user perspectives

Purpose: The purpose of this project was to identify wheelchair skills currently being taught to new manual wheelchair users, identify areas of importance for manual wheelchair skills' training during initial rehabilitation, identify similarities and differences between the perspectives of health care professionals and manual wheelchair users and use the ICF to organize themes related to rehabilitation and learning how to use a manual wheelchair. Method: Focus groups were conducted with health care professionals and experienced manual wheelchair users. ICF codes were used to identify focus group themes. Results: The Activities and Participation codes were more frequently used than Structure, Function and Environment codes. Wheelchair skills identified as important for new manual wheelchair users included propulsion techniques, transfers in an out of the wheelchair, providing maintenance to the wheelchair and navigating barriers such as curbs, ramps and rough terrain. Health care professionals and manual wheelchair users identified the need to incorporate the environment (home and community) into the wheelchair training program. Conclusions: Identifying essential components for training the proper propulsion mechanics and wheelchair skills in new manual wheelchair users is an important step in preventing future health and participation restrictions.

• Implications for Rehabilitation

• Wheelchair skills are being addressed frequently during rehabilitation at the activity-dependent level.

• Propulsion techniques, transfers in an out of the wheelchair, providing maintenance to the wheelchair and navigating barriers such as curbs, ramps and rough terrain are important skills to address during wheelchair training.

• Environment factors (in the home and community) are important to incorporate into wheelchair training to maximize safe and multiple-environmental-setting uses of manual wheelchairs.

• The ICF has application to understanding manual wheelchair rehabilitation for wheelchair users and therapists for improving the understanding of manual wheelchair use.

     

Design of a randomized-controlled trial on low-intensity aerobic wheelchair exercise for inactive persons with chronic spinal cord injury

Purpose: To investigate effects and working mechanisms of low-intensity aerobic wheelchair exercise on fitness, (upper-body) health and active lifestyle in inactive persons with chronic spinal cord injury (SCI). Methods: A multicenter randomized-controlled trial (RCT) in 40 inactive manual wheelchair users (aged 28–65y) with chronic paraplegia or tetraplegia (time since injury >10y). Subjects will be randomly assigned to an intervention or a control group. The intervention will consist of 16 weeks (2 times per week, 30?min per session) of low-intensity aerobic handrim wheelchair exercise (30–40% HRR) on a treadmill. Repeated measurements will be performed before starting the intervention or entrance of the control group, and after week 8, 16 and 42 following the start. The primary outcome will be wheelchair-specific physical fitness. Secondary outcomes will be upper-body pain and discomfort, shoulder load, propulsion technique, wheelchair skill performance and physical activity levels. Conclusions: Results of this first RCT on low-intensity aerobic wheelchair exercise for inactive persons with chronic SCI can improve SCI-specific exercise guidelines and provide an evidence-base for an aftercare program aimed at preserving fitness, health and active lifestyle of persons aging with SCI.

Implications for Rehabilitation

• Low-intensity wheelchair aerobic exercise may be effective for improving fitness, (upper-body) health and active lifestyle of inactive persons with chronic SCI, without the high dropout rates that plague exercise programs for this population.

• Results of this study can 1) improve SCI-specific aerobic exercise guidelines and 2) provide an evidence-base for a long-term aftercare rehabilitation program for persons aging with SCI.

• As this study is embedded in Dutch rehabilitation practice, chances of knowledge transfer and implementation are high, and strengthen the Dutch SCI rehabilitation network.

     

Driving performance in a power wheelchair simulator

Purpose: A power wheelchair simulator can allow users to safely experience various driving tasks. For such training to be efficient, it is important that driving performance be equivalent to that in a real wheelchair. This study aimed at comparing driving performance in a real and in a simulated environment. Method: Two groups of healthy young adults performed different driving tasks, either in a real power wheelchair or in a simulator. Smoothness of joystick control as well as the time necessary to complete each task were recorded and compared between the two groups. Driving strategies were analysed from video recordings. The sense of presence, of really being in the virtual environment, was assessed through a questionnaire. Results: Smoothness of joystick control was the same in the real and virtual groups. Task completion time was higher in the simulator for the more difficult tasks. Both groups showed similar strategies and difficulties. The simulator generated a good sense of presence, which is important for motivation. Conclusions: Performance was very similar for power wheelchair driving in the simulator or in real life. Thus, the simulator could potentially be used to complement training of individuals who require a power wheelchair and use a regular joystick.

Implications for Rehabilitation

• Individuals who require a power wheelchair for mobility often lack sufficient training, which may be supplemented through the use of a simulator.

• For such training to be efficient, it is important that performance in the simulator and in a real wheelchair be equivalent.

• This study showed that driving performance, strategies used and difficulties encountered were very similar, for groups of healthy adults driving in the simulator or in a real power wheelchair.

     

Development of a wheelchair maintenance training programme and questionnaire for clinicians and wheelchair users

Purpose of state: The aims of this study were to develop a Wheelchair Maintenance Training Programme (WMTP) as a tool for clinicians to teach wheelchair users (and caregivers when applicable) in a group setting to perform basic maintenance at home in the USA and to develop a Wheelchair Maintenance Training Questionnaire (WMT-Q) to evaluate wheelchair maintenance knowledge in clinicians, manual and power wheelchair users.

Methods: The WMTP and WMT-Q were developed through an iterative process.

Results: A convenience sample of clinicians (n?=?17), manual wheelchair (n ∞ 5), power wheelchair users (n?=?4) and caregivers (n?=?4) provided feedback on the training programme. A convenience sample of clinicians (n?=?38), manual wheelchair (n?=?25), and power wheelchair users (n?=?30) answered the WMT-Q throughout different phases of development. The subscores of the WMT-Q achieved a reliability that ranged between ICC(3,1)?=?0.48 to ICC(3,1)?=?0.89. The WMTP and WMT-Q were implemented with 15 clinicians who received in-person training in the USA using the materials developed and showed a significant increase in all except one of the WMT-Q subscores after the WMTP (p?<?0.007).

Conclusion: The WMTP will continue to be revised as it is further implemented. The WMT-Q is an acceptable instrument to measure pre- and post-training maintenance knowledge.

• Implications for Rehabilitation

• The Wheelchair Maintenance Training Program can be used to educate rehabilitation clinicians and technicians to improve wheelchair service and delivery to end users.

• This training complements the World Health Organization basic wheelchair service curriculum, which only includes training of the clinicians, but does not include detailed information to train wheelchair users and caregivers.

• This training program offers a time efficient method for providing education to end users in a group setting that may mitigate adverse consequences resulting from wheelchair breakdown.

• This training program has significant potential for impact among wheelchair users in areas where access to repair services is limited.

     

The potential impact of intelligent power wheelchair use on social participation: perspectives of users,caregivers and clinicians

Purpose: To explore power wheelchair users’, caregivers’ and clinicians’ perspectives regarding the potential impact of intelligent power wheelchair use on social participation. Methods: Semi-structured interviews were conducted with power wheelchair users (n?=?12), caregivers (n?=?4) and clinicians (n?=?12). An illustrative video was used to facilitate discussion. The transcribed interviews were analyzed using thematic analysis. Results: Three main themes were identified based on the experiences of the power wheelchair users, caregivers and clinicians: (1) increased social participation opportunities, (2) changing how social participation is experienced and (3) decreased risk of accidents during social participation. Conclusion: Findings from this study suggest that an intelligent power wheelchair would enhance social participation in a variety of important ways, thereby providing support for continued design and development of this assistive technology.

• Implications for Rehabilitation

• An intelligent power wheelchair has the potential to:

• Increase social participation opportunities by overcoming challenges associated with navigating through crowds and small spaces.

• Change how social participation is experienced through “normalizing” social interactions and decreasing the effort required to drive a power wheelchair.

• Decrease the risk of accidents during social participation by reducing the need for dangerous compensatory strategies and minimizing the impact of the physical environment.

     

Shoulder kinetics during start-up and propulsion with a manual wheelchair within the initial phase of uninstructed training

Purpose: Wheelchair locomotion is constraining for the upper limbs and involves a set of motor tasks that need to be learnt by a novice user. To understand this integration process, we investigated the evolution of shoulder kinetics during start-up and propulsion within the initial phase of low-intensity uninstructed training.

Materials and methods: Seventeen novice able-bodied subjects performed a 120-min uninstructed practice distributed over 4 weeks. During the initial and final sessions, upper limbs kinematics and hand-rim kinetics were continuously collected. Inverse kinematics and dynamics coupled to a three-dimensional linked-segment model were used to compute shoulder net moments.

Results: Participants increased the speed of the wheelchair with practice. In average, an increase of shoulder net moments and mechanical work during the push phase was observed. Conversely, during the recovery phase, participants slightly increased shoulder power but maintained a similar level of shoulder loading. However, individual evolutions allowed the definition of two groups defined as: “increasers”, who increased shoulder loading and mechanical work versus “decreasers”, who managed to limit shoulder loading while improving the wheelchair speed.

Conclusion: These findings underline that individual adaptation strategies are essential to take into account when designing a rehabilitation protocol for wheelchair users.

• Implications for Rehabilitation

• The learning process of manual wheelchair locomotion is essential for the assimilation of motor tasks leading individuals to select their propulsion technique.

• Novice users display different learning strategies: some people increase shoulder loading very early but others spontaneously manage to increase the wheelchair speed while maintaining a constant level of shoulder loading.

• Wheelchair rehabilitation programs should be individualized to take into account the subject-specific learning strategy.

     

The relationship between functional disability and health-related quality of life in patients with a rotator cuff tear

Purpose:To determine the relationship between functional disability and health-related quality of life (HRQoL) in rotator cuff tear (RCT) patients. Method:In 67 RCT patients (mean age, 54 years; 57% males), functional disability was self-reported with the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), HRQoL with the Short-Form 36 Health Survey (SF-36), and pain by visual analogue scale. ASES results were divided into tertiles (12–38, 39–51, and 52–82). Results:Mean ASES score was 48 (range, 12–82). Patients with the highest functional disability and highest pain level had the lowest HRQoL. For the highest, middle, and lowest ASES categories, respectively, mean SF-36 Physical Component Summary (PCS) scores were 35 SD 5, 36 SD 8, and 41 SD 6 (p< 0.001) (r = 0.47 for ASES vs. PCS; p< 0.001), and Mental Component Summary (MCS) scores were 50 SD 13, 56 SD 10, and 58 SD 8 (p = 0.011) (r = 0.37 for ASES vs. MCS; p= 0.003). Conclusions: Patients with higher functional disability had lower HRQoL. RCT extensively affects patients’ lives; therefore, capturing both generic and shoulder-specific measures of RCT problems is recommended.

Implications for Rehabilitation

• Rotator cuff tears (RCTs) result from injury or degeneration, and tear prevalence increases with age.

• RCT causes disabling pain, decline in muscle strength and shoulder mobility.

• RCT patients with decreased functioning have impaired quality of life.

     

A new design for an old concept of wheelchair pushrim

Purpose: Report on the development of an ergonomic manual wheelchair pushrim and evaluate the user’s perception of the quality of the device. Method: Based on anthropometric features and ergonomic concepts, a new wheelchair pushrim was designed, and a prototype was manufactured in polyurethane, using the rapid prototyping technique and serial production of parts by molding. The prototype was tested by a sample of wheelchair users, who rated the perceived quality of the device after testing both the new and conventional pushrims in a wheelchair propulsion experimental protocol. Results: The new ergonomic pushrim was found to be, in general, better than the conventional round tube pushrim. Specifically, experienced wheelchair users found the new wheelchair pushrim better in terms of easy and comfortable propulsion, braking and maneuvering of the wheelchair, and appearance. Conclusions: The new wheelchair pushrim provides a proper fit for the hands due to its ergonomic design and its polyurethane composition, making wheelchair propulsion easier and more comfortable than the conventional wheelchair pushrim. Assistive technology devices should be design based on ergonomic concepts that involve less effort and offer greater comfort for the user.

Implications for Rehabilitation

• Manual wheelchair propulsion has been related with upper limb injuries that may potentially limit functionality.

• The conventional pushrim does not meet the need for a firm and stable grip, requiring further effort to hold the pushrim during manual propulsion that may cause discomfort, pain and contribute for developing upper limb injuries.

• In a relatively small sample of wheelchair users, this study shows that an ergonomically designed pushrim makes manual propulsion easier and more comfortable compared to the conventional pushrim.

     

Differences in outcomes between the JoyBar control and standard wheelchair joystick control on two maneuverability tasks: a pilot study

Purpose: To determine if older adult, novice wheelchair users who drive a power wheelchair with a JoyBar control complete maneuverability tasks in less time and with less error than those who drive a power wheelchair with a standard joystick control.

Materials and methods: A parallel randomized controlled trial design conducted at a medical rehabilitation and research centre with ambulatory older adults aged 60 and above (n?=?27). The intervention was the JoyBar alternative wheelchair control. The primary outcome measure was total time to complete each of the two maneuverability tasks. The secondary outcome measure was total number of errors during each of the maneuverability tasks.

Results: An independent, two sampled t-test was conducted and revealed that the JoyBar group took a greater amount of time to complete both maneuverability tasks than the control group (p?p?Conclusions: Maneuverability of a powered wheelchair by novice wheelchair users was not improved through the use of the JoyBar when compared to a standard wheelchair joystick, as measured by rates of error and time to complete maneuverability tasks.

• Implications for rehabilitation

• Clients who are new to powered wheelchair use may perform maneuverability tasks faster, with equivalent accuracy, using a standard joystick versus the JoyBar.

• Clients who use a JoyBar may require adjustments to the programming of their wheelchair to ensure optimal performance.

• Additional training may be required to achieve proficiency in maneuverability tasks with a JoyBar versus a standard joystick.

     

Power wheelchair driving challenges in the community: a users’ perspective

Purpose: There is limited information on the difficulties individuals experience in manoeuvring their power wheelchairs during daily activities. The aim of this study was to describe the nature and context of power wheelchair driving challenges from the perspective of the user. Methods: A qualitative design using semi-structured interviews with power wheelchair users. Qualitative content analysis was used to identify themes. Results: Twelve experienced power wheelchair users were interviewed. Findings revealed that power wheelchair driving difficulties were related to the accomplishment of activities of daily living, and the influence of environmental context. Four key themes emerged: (1) difficulties accessing and using public buildings-facilities, (2) outdoor mobility, (3) problems in performing specific wheelchair mobility tasks/manoeuvres and (4) barriers and circumstances that are temporary, unforeseen or specific to a particular context. Conclusion: This qualitative study furthers our understanding of the driving difficulties powered wheelchair (PW) users experience during daily activities. This knowledge will assist clinicians and researchers in two areas: in choosing assessment measures that are ecologically valid for power wheelchair users; and, in identifying and refining the content of training programs specific to the use of power wheelchairs.

• Implications for Rehabilitation

• A better understanding of the everyday challenges individuals experience in driving their power wheelchair will assist clinicians and researchers in:

• Choosing assessment measures and identifying training programs for this population.

• Refining the content of power wheelchair training programs.

     

Everyday life for users of electric wheelchairs – a qualitative interview study

Purpose: The aim of this paper is to explore how users of electric wheelchairs experience their everyday life and how their electric wheelchairs influence their daily occupation. Occupation is defined as a personalized dynamic interaction between person, task and environment, and implies the value and meaning attached. Method: Nine semi-structured interviews were conducted with experienced electric wheelchair users. ValMo was used as the theoretical framework for both interviewing and the analysis. The transcribed interviews were analysed using thematic analysis. Results: Findings revealed key elements in electric wheelchair users’ experience of how the use of a wheelchair influences everyday life and occupation. Four central themes emerged from the participants’ experiences 1) The functionality of the wheelchair, 2) The wheelchair as an extension of the body, 3) The wheelchair and social life, and 4) The wheelchair and identity issues. The themes were interrelated and show how all levels of occupation were influenced both in a positive and negative way, and how it affected identity. Conclusions: It is essential that professionals working with electric wheelchair users are aware of how all levels of occupation and identity are influenced by using a wheelchair. This will assist professionals in supporting the users living an autonomous and meaningful life.

Implications for Rehabilitation

• All levels of occupation and identity are influenced by using a wheelchair.

• It is important that the electric wheelchair functions as an extension of the user’s body and that surroundings are made as accessible as possible.

• When choosing an electric wheelchair it is important that professionals make assessments that embrace all levels of the user’s occupation.

     

Pilates for people with multiple sclerosis who use a wheelchair: feasibility,efficacy and participant experiences

Abstract

Purpose: This mixed methods study aimed to explore the feasibility, efficacy and the participants’ experiences of a Pilates programme for people with Multiple Sclerosis (pwMS) who use a wheelchair. Method: Fifteen pwMS took part in the 12-week Pilates programme. At baseline and after 6 and 12 weeks of the programme, sitting stability, measured as maximum progression of the Centre of Pressure when leaning sideways (COPmax), posture, pain on a Visual Analogue Scale, function, fatigue and the impact of MS (MSIS29) were assessed. Ten participants took part in two focus groups within six weeks of the completion of the programme. Results: Significant improvements at the 12-week assessment were found in COPmax (p?=?0.046), sitting posture (p?=?0.004), pain in the shoulders (p?=?0.005) and back (p?=?0.005) and MSIS29 (p?=?0.006). The majority of participants described various physical, functional, psychological and social benefits from participation that reflected increased confidence in activities of daily living. Enjoyment of the classes was expressed by all, and most wished to continue participation. Conclusions: Pilates appears to be efficacious in improving sitting stability and posture and decreasing pain and was also well tolerated by wheelchair users with MS. Further mixed methods studies are warranted.

• Implications for Rehabilitation

• Group-based core stability exercise or Pilates for people with MS who use wheelchair is a feasible and safe way of exercising for this patient group.

• Pilates exercises for people moderately to severely affected by MS resulted in a decrease in back and shoulder pain and improvement in sitting balance.

• Future appropriately powered randomised controlled studies into Pilates for people with MS reliant on wheelchair are warranted.

     

The ability of preoperative factors to predict patient-reported disability following surgery for rotator cuff pathology

Purpose: Minimal research has examined the prognostic ability of shoulder examination data or psychosocial factors in predicting patient-reported disability following surgery for rotator cuff pathology. The purpose of this study was to examine these factors for prognostic value in order to help clinicians and patients understand preoperative factors that impact disability following surgery.

Methods: Sixty-two patients scheduled for subacromial decompression with or without supraspinatus repair were recruited. Six-month follow-up data were available for 46 patients. Patient characteristics, history of the condition, shoulder impairments, psychosocial factors, and patient-reported disability questionnaires were collected preoperatively. Six months following surgery, the Western Ontario Rotator Cuff Index (WORC) and global rating of change dichotomized subjects into responders versus nonresponders. Logistic regression quantified prognostic ability and created the most parsimonious model to predict outcome.

Results: Being on modified job duty (OR?=?.17, 95%CI: 0.03–0.94), and having a worker’s compensation claim (OR?=?0.08, 95%CI: 0.01–0.74) decreased probability of a positive outcome, while surgery on the dominant shoulder (OR?=?11.96, 95%CI: 2.91–49.18) increased probability. From the examination, only impaired internal rotation strength was a significant univariate predictor. The Fear-avoidance Beliefs Questionnaire (FABQ) score (OR?=?0.95, 95%CI: 0.91–0.98) and the FABQ_work subscale (OR?=?0.92, 95%CI: 0.87–0.97) were univariate predictors. In the final model, surgery on the dominant shoulder (OR?=?8.9, 95%CI 1.75–45.7) and FABQ_work subscale score?≤25 (OR?=?15.3, 95%CI 2.3–101.9) remained significant.

Discussion: Surgery on the dominant arm resulted in greater improvement in patient-reported disability, thereby increasing the odds of a successful surgery. The predictive ability of the FABQ_work subscale highlights the potential impact of psychosocial factors on patient-reported disability.

• Implications for Rehabilitation

• Impairment-based shoulder measurements were not strong predictors of patient-reported outcome.

• Having high fear-avoidance behavior scores on the FABQ, especially the work subscale, resulted in a much lower chance of responding well to rotator cuff surgery as measured by self-reported disability.

• Having surgery on the dominant shoulder, as compared to the nondominant side, resulted in larger improvements in disability levels.

     

The effects of four different stroke patterns on manual wheelchair propulsion and upper limb muscle strain

Purpose: To evaluate the effects of stroke pattern on handrim biomechanics and upper limb electromyography (EMG) in experienced wheelchair users. Method: Subjects propelled their own wheelchair on a level, motor-driven treadmill using each of four identified stroke patterns: arcing, double loop (DL), semi-circular (SC) and single loop (SL). Upper limb EMG and measurements taken from an instrumented wheelchair wheel were compared for each pattern. A one-way ANOVA with Bonferroni correction (p < 0.05) was used to check for significant differences. Results: The DL and SC patterns produced the best overall results. The DL pattern led to a significantly longer contact angle and significantly less braking moment than the SL and arcing patterns, and a significantly lower cadence than the SL pattern. The SC pattern led to a significantly longer contact angle than the SL pattern and the lowest peak force and impact of any pattern. There were no significant differences in integrated EMG (IEMG); however, the DL and arcing patterns produced lower combined IEMG values. Conclusions: When traversing level terrain, wheelchair users should push with either the DL or SC patterns. Between the two, the DL pattern required less muscle activity and may be a better choice for experienced wheelchair users.

Implications for Rehabilitation

• Manual wheelchair propulsion is essential for many individuals with lower limb impairments; however, it often leads to upper limb pain, which can limit mobility and quality of life.

• Stroke patterns that reduce upper limb demand can help users reduce their risk of pain.

• The double loop (DL) and semi-circular (SC) stroke patterns produced the best combinations of handrim biomechanics and are therefore recommended for use.

• Due to an observed increase in elbow muscle activity, individuals who use the DL pattern are not encouraged to switch to the SC pattern.
