Extent to Which Caregivers Enhance the Wheelchair Skills Capacity and Confidence of Power Wheelchair Users: A Cross-Sectional Study.

OBJECTIVE: To test the hypothesis that caregivers enhance the wheelchair skills capacity and confidence of the power wheelchair users to whom they provide assistance, and to describe the nature of that assistance. DESIGN: Multicenter cross-sectional study. SETTING: Rehabilitation centers and communities. PARTICIPANTS: Participants (N=152) included caregivers (n=76) and wheelchair users (n=76). INTERVENTIONS: None. MAIN OUTCOME MEASURES: Version 4.3 of the Wheelchair Skills Test (WST) and the Wheelchair Skills Test-Questionnaire (WST-Q). For each of the 30 individual skills, we recorded data about the wheelchair user alone and in combination (blended) with the caregiver. RESULTS: The mean total WST capacity scores ± SD for the wheelchair users alone and blended were 78.1%±9.3% and 92.4%±6.1%, respectively, with a mean difference of 14.3%±8.7% (P<.0001). The mean WST-Q capacity scores ± SD were 77.0%±10.6% and 93.2%±6.4%, respectively, with a mean difference of 16.3%±9.8% (P<.0001). The mean WST-Q confidence scores ± SD were 75.5%±12.7% and 92.8%±6.8%, respectively, with a mean difference of 17.5%±11.7% (P<.0001). The mean differences corresponded to relative improvements of 18.3%, 21.0%, and 22.9%, respectively. The nature and benefits of the caregivers' assistance could be summarized in 7 themes (eg, caregiver provides verbal support [cueing, coaching, reporting about the environment]). CONCLUSIONS: Caregivers significantly enhance the wheelchair skills capacity and confidence of the power wheelchair users to whom they provide assistance, and they do so in a variety of ways. These findings have significance for wheelchair skills assessment and training.

Getting a Manual Wheelchair Over a Threshold Using the Momentum Method: A Descriptive Study of Common Errors.

OBJECTIVES: To (1) document the success of learners' attempts to overcome a threshold in a manual wheelchair while using the momentum method; (2) describe the frequency and nature of any errors observed; and (3) compare the characteristics of participants who were or were not successful on their first attempts. DESIGN: Cross-sectional, observational study following Strengthening the Reporting of Observational Studies in Epidemiology guidelines. SETTING: Indoor obstacle course in a rehabilitation center. PARTICIPANTS: Able-bodied students (N=214) learning the threshold skill. INTERVENTION: Participants attempted to get over the Wheelchair Skills Test (WST) threshold (2cm high, 1.5m wide, and 10cm in the line of progression) in a manual wheelchair. MAIN OUTCOME MEASURES: From each participant's video recording of the first attempt, we assigned a WST score for the skill and described any errors noted. RESULTS: The WST scores for the first attempts were "pass" for 16 (7.5%), "pass with difficulty" for 100 (46.7%), and "fail" for 98 (45.8%). Eventually, requiring up to 6 attempts, 203 participants (94.9%) were successful (pass or pass with difficulty). Twenty-six different error types were identified. With the use of logistic regression analysis, the odds ratio of failing on the first attempt for women versus men was 2.71 (95% confidence interval, 1.23-6.00) (P=.0138). CONCLUSIONS: Only about half of able-bodied people learning the threshold skill using the momentum method are successful on their first attempts, although almost all are successful with further practice and feedback. During the first attempts, there are a wide variety of errors, primarily in the popping phase of the skill. Those who are successful on their first attempts are more likely to be men. These findings have implications for the assessment and training of the threshold skill.

Wheelchair Skills Capacity and Performance of Manual Wheelchair Users With Spinal Cord Injury.

OBJECTIVES: To describe the wheelchair skills capacity and performance of experienced manual wheelchair users with spinal cord injury (SCI) and to assess measurement properties of the Wheelchair Skills Test (WST) and Wheelchair Skills Test Questionnaire (WST-Q). DESIGN: Cross-sectional descriptive study involving within-subject comparisons. SETTING: Four Spinal Cord Injury Model Systems centers. PARTICIPANTS: Manual wheelchair users with SCI (N=117). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: WST and WST-Q version 4.2 as well as measures for Confidence, Basic Mobility, Independence, Ability to Participate, Satisfaction, and Pain Interference. RESULTS: The median (interquartile range) values for WST capacity, WST-Q capacity, and WST-Q performance were 81.0% (69.0%-90.0%), 88.0% (77.0%-97.0%), and 76.0% (66.3%-84.0%). The total WST capacity scores correlated significantly with the total WST-Q capacity scores (r=.76; P<.01) and WST-Q performance scores (r=.55; P<.01). The total WST-Q capacity and WST-Q performance scores were correlated significantly (r=.63; P<.001). Success rates were <75% for 10 of the 32 (31%) individual skills on the WST and 6 of the 32 (19%) individual skills on the WST-Q. Regression models for the total WST and WST-Q measures identified statistically significant predictors including age, sex, body mass index, and/or level of injury. The WST and WST-Q measures correlated significantly with the Confidence, Basic Mobility, Independence, or Pain Interference measures. CONCLUSIONS: Many people with SCI are unable to or do not perform some of the wheelchair skills that would allow them to participate more fully. More wheelchair skills training may enhance participation and quality of life of adults with SCI. The WST and WST-Q exhibit good content, construct, and concurrent validity.

Effectiveness of a Wheelchair Skills Training Program for Powered Wheelchair Users: A Randomized Controlled Trial.

OBJECTIVES: To test the hypothesis that powered wheelchair users who receive the Wheelchair Skills Training Program (WSTP) improve their wheelchair skills in comparison with a control group that receives standard care, and secondarily to assess goal achievement, satisfaction with training, retention, injury rate, confidence with wheelchair use, and participation. DESIGN: Randomized controlled trial. SETTING: Rehabilitation centers and communities. PARTICIPANTS: Powered wheelchair users (N=116). INTERVENTION: Five 30-minute WSTP training sessions. MAIN OUTCOME MEASURES: Assessments were done at baseline (t1), posttraining (t2), and 3 months posttraining (t3) using the Wheelchair Skills Test Questionnaire (WST-Q version 4.1), Goal Attainment Score (GAS), Satisfaction Questionnaire, injury rate, Wheelchair Use Confidence Scale for Power Wheelchair Users (WheelCon), and Life Space Assessment (LSA). RESULTS: There was no significant t2-t1 difference between the groups for WST-Q capacity scores (P=.600), but the difference for WST-Q performance scores was significant (P=.016) with a relative (t2/t1 × 100%) improvement of the median score for the intervention group of 10.8%. The mean GAS ± SD for the intervention group after training was 92.8%±11.4%, and satisfaction with training was high. The WST-Q gain was not retained at t3. There was no clinically significant difference between the groups in injury rate and no statistically significant differences in WheelCon or LSA scores at t3. CONCLUSIONS: Powered wheelchair users who receive formal wheelchair skills training demonstrate modest, transient posttraining improvements in their WST-Q performance scores, have substantial improvements on individualized goals, and are positive about training.

Wheelchair skills training for caregivers of manual wheelchair users: a randomized controlled trial comparing self-study and remote training.

In this single-blind randomized controlled trial, we tested the hypotheses that, in comparison with control participants receiving only self-study materials (SS group), caregivers of manual wheelchair users who additionally receive remote training (RT group) have greater total Wheelchair Skills Test Questionnaire (WST-Q) performance and confidence scores post-training and at follow-up; and that self-study and remote training each individually lead to such gains. We studied 23 dyads of wheelchair users and their caregivers. Caregivers in the SS group received a handbook and videorecording. Those in the RT group also received up to four real-time ("synchronous") sessions remotely. The WST-Q 5.1 was administered pre-training (T1), post-training (T2), and after a 3-month follow-up (T3). The mean total WST-Q scores of both groups rose slightly at each new assessment. For the T2-T1 and T3-T1 gains, there were no statistically significant differences between the groups for either WST-Q performance or WST-Q confidence. For performance, the T2-T1 gain was statistically significant for the RT group and the T3-T2 gain was statistically significant for the SS group. For both groups, the T3-T1 gains in performance were statistically significant with gains of 12.9% and 18.5% relative to baseline for the SS and RT groups. For confidence, only the T3-T1 gain for the SS group was statistically significant with a gain of 4.5% relative to baseline. Although less than the gains previously reported for in-person training, modest but important gains in total WST-Q performance scores can be achieved by self-study, with or without remote training. REGISTRATION NUMBER: NCT03856749.

Self-study can improve the manual wheelchair skills of caregivers.Remote training can improve the manual wheelchair skills of caregivers.Improvements are slightly less than those reported in the literature for in-person training.

Practices and views of wheelchair service providers regarding wheelchair-skills training for clients and their caregivers: a global online survey.

PURPOSE: To determine the extent to which wheelchair service providers conduct wheelchair-skills training, the nature of training, and the providers' perceptions on training. MATERIALS AND METHODS: Anonymous global online survey consisting of 29 questions administered via the REDCap electronic data-capture tool to English-speaking wheelchair service providers. RESULTS: We received 309 responses from wheelchair service providers in 35 countries. Of the respondents who responded to the question "…do you typically provide wheelchair-skills training…?" 227 (81.6%) reported "yes, always" or "yes, usually" for clients and 213 (81.9%) for caregivers. The median duration of training sessions for clients and caregivers was 45 and 30 min; the median number of sessions was 2 for both. Regarding the importance of training, 251 (94.4%) answered "very important" for clients and 201 (78.5%) for caregivers. For clients and caregivers, 182 (68.4%) and 191 (74.3%) of respondents considered themselves adequately prepared for the trainer role. A variety of barriers and facilitators to training were identified. CONCLUSIONS: Most wheelchair service providers report that they provide wheelchair-skills training for clients and their caregivers, most consider such training to be important and most consider themselves adequately prepared for the training role. However, the amount of training is generally minimal. Further efforts are needed to address the identified barriers to training.IMPLICATIONS FOR REHABILITATIONMost wheelchair-service providers report that they provide wheelchair-skills training.Most consider such training to be important.Most consider themselves adequately prepared.However, the extent of training is generally minimal.These findings have implications for clinicians, educators, and policymakers.

A Remote-Learning Course can improve the subjective wheelchair-skills performance and confidence of wheelchair service providers: an observational cohort study.

PURPOSE: To test the hypothesis that a Remote-Learning Course improves the subjective wheelchair-skills performance and confidence of wheelchair service providers, and to determine the participants' views on the Course. METHODS: This was an observational cohort study, with pre-post comparisons. To meet the objectives of the six-week Course, the curriculum included self-study and weekly one-hour remote meetings. Participants submitted their Wheelchair Skills Test Questionnaire (WST-Q) (Version 5.3.1) "performance" and "confidence" scores before and after the Course. Participants also completed a Course Evaluation Form after the Course. RESULTS: The 121 participants were almost all from the rehabilitation professions, with a median of 6 years of experience. The mean (SD) WST-Q performance scores rose from 53.4% (17.8) pre-Course to 69.2% (13.8) post-Course, a 29.6% relative improvement (p < 0.0001). The mean (SD) WST-Q confidence scores rose from 53.5% (17.9) to 69.5% (14.3), a 29.9% relative improvement (p < 0.0001). Correlations between performance and confidence were highly significant (p < 0.0001). The Course Evaluation indicated that most participants found the Course useful, relevant, understandable, enjoyable, "just right" in duration, and most stated that they would recommend the Course to others. CONCLUSIONS: Although there is room for improvement, a Remote-Learning Course improves the subjective wheelchair-skills performance and confidence scores of wheelchair service providers by almost 30%, and participants were generally positive about the Course.

A Remote-Learning Course improves the subjective wheelchair-skills performance and confidence scores of wheelchair service providers by almost 30%.Participants were generally positive about the Course.

Qualitative experiences of new motorised mobility scooter users relevant to their scooter skills: a secondary analysis.

OBJECTIVE: To explore the experiences of new motorised mobility scooter users from the perspectives of the assessment and training of scooter skills. DESIGN: Descriptive secondary analysis of qualitative data. SETTING: Community. PARTICIPANTS: 20 New users of motorised mobility scooters. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Directed qualitative analysis of up to four semi-structured interviews over the course of the first year of scooter use, to identify themes and sub-themes that could inform recommendations regarding assessment and training protocols. RESULTS: We identified two themes. The first related to potential new content. As one example of the sub-themes, there were many excerpts that dealt with the use of skills in various combinations and permutations that were used to carry out activities during everyday life and participate in society. These excerpts suggested the importance of training skills in combination to facilitate skill transfer (or generalizability). The second theme is related to enhancements of existing content. As one example of the sub-themes, there were several excerpts that dealt with scooter security. These excerpts led to the recommendation that removing and inserting the scooter key should be added to the assessment criteria for the "turns power on and off" skill of the Wheelchair Skills Test (WST) and its questionnaire version (WST-Q). CONCLUSIONS: The experiences of scooter users over the first year of receiving a scooter appear to be relevant to the assessment and training of scooter skills and suggest themes for further study. Clinical trial registration number: NCT02696213 IMPLICATIONS FOR REHABILITATIONThe experiences of new scooter users are highly relevant to the assessment and training of scooter skills.These experiences suggest both potential new content and enhancements of existing content to the Wheelchair Skills Program Manual.

Effect of travel direction and wheelchair position on the ease of a caregiver getting an occupied wheelchair across a soft surface: a randomized crossover trial.

PURPOSE: To test the hypotheses that, in comparison with pushing an occupied upright manual wheelchair forward, pulling backward on the push-handles improves the objective and subjective ease with which a caregiver can get the wheelchair across a soft surface (e.g., grass, mud, sand, gravel); and the ease with which a caregiver can get the wheelchair across a soft surface improves if the wheelchair is tipped back into the wheelie position. METHODS: We used a randomized crossover trial with within-participant comparisons to study 32 able-bodied pairs of simulated caregivers and wheelchair occupants. The caregiving participants moved an occupied manual wheelchair 5 m across a soft surface (7.5-cm-thick gym mats) under four conditions (upright-forward, upright-backward, wheelie-forward and wheelie-backward) in random order. The main outcome measure was time (to the nearest 0.1 s) and the main secondary measure was the ease of performance (5-point Likert scale). RESULTS: The upright-backward condition was the fastest (p < 0.05) and had the highest ease-of-performance scores. In the forward direction, there was no statistically significant difference in the time required between the upright and wheelie positions, but the wheelie position was considered easier. CONCLUSIONS: Although further study is needed, our findings suggest that caregivers should pull rather than push occupied wheelchairs across soft surfaces. In the forward direction, caregivers may find the wheelie position easier than the upright condition. These techniques have the potential to both improve the effectiveness of and reduce injuries to caregivers. Clinical Trial Registration Number: NCT 04998539Implications for RehabilitationCaregivers should pull rather than push occupied manual wheelchairs across soft surfaces.In the forward direction, caregivers may find the wheelie position easier than and preferable to the upright condition.These techniques have the potential to both improve the effectiveness of and reduce injuries to caregivers.

Effect of seat height on manual wheelchair foot propulsion, a repeated-measures crossover study: part 2 - wheeling backward on a soft surface.

PURPOSE: The aim of this study was to test the hypotheses that, during manual-wheelchair foot propulsion backward on a soft surface, lowering the seat height increases speed, push frequency and push effectiveness, and decreases perceived difficulty. MATERIALS AND METHODS: In a repeated-measures crossover study, 50 able-bodied participants used one foot to propel a manual wheelchair 5 m backward on a soft surface at 5 seat heights, ranging from 5.08 cm below to about 5.08 cm above lower-leg length, in random order. We recorded Wheelchair Skills Test (WST) capacity scores and used the Wheelchair Propulsion Test (WPT) to calculate speed (m/s), push frequency (cycles/s) and push effectiveness (m/cycle). We also recorded the participants' perceived difficulty (0-4) and video-recorded each trial. RESULTS: WST capacity scores were reduced at the higher seat heights. Using repeated-measures models (adjusted for age, sex and order), there were negative relationships between seat height and speed (p < 0.0001) and push effectiveness (p < 0.0001). Lowering the seat height by 5.08 cm below lower-leg length corresponded to improvements in speed of 0.097 m/s and in push effectiveness of 0.101 m/cycle. The trend for push frequency was also significant (p = 0.035) but the effect size was smaller. Perceived difficulty increased with seat height (p < 0.0001). The video-recordings provided qualitative kinematic data regarding the seated "gait cycles". CONCLUSIONS: During manual-wheelchair foot propulsion backward on a soft surface, lowering the seat height increases speed and push effectiveness, and decreases perceived difficulty.IMPLICATIONS FOR REHABILITATIONBackward wheelchair foot propulsion on soft surfaces is affected by seat height.Speed (m/s) is improved if the seat height is lowered.Push effectiveness (m/gait cycle) is improved if the seat height is lowered.Perceived difficulty of propulsion is lower if the seat height is lowered.

Manual wheelchair skills capacity and safety of residents of a long-term-care facility.

OBJECTIVES: To evaluate the manual wheelchair skills capacity and safety of residents of a long-term-care (LTC) facility. Our secondary objectives were to describe the wheelchairs that the participants used and to document the participants' perceptions of their assessment experiences. DESIGN: A cross-sectional, descriptive, mixed-methods study. SETTING: One hundred and seventy-five bed LTC veterans' facility. PARTICIPANTS: Manual wheelchair users (N=13), a sample of convenience consisting of 10 men and 3 women, with a mean ± SD age of 86.8±6.4 years. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Wheelchair Skills Test (WST), version 4.1, the Wheelchair Specification Form, and qualitative observations. RESULTS: The mean ± SD total WST scores for capacity and safety were 35.3%±15.4% and 92.5%±6.1%. The mean ± SD number of sessions required was 3.0±1.1 and the mean ± SD total time required was 54.8±20.2 minutes. The analysis of the individual skills and participants provided valuable insights. Only 1 (8%) of the 13 wheelchairs was considered to have proper components and set-up for self-propulsion. Participants generally reported enjoying the wheelchair-skills experience. CONCLUSIONS: The residents of a LTC veterans' facility whom we studied had significant difficulties when attempting a set of manual wheelchair skills, but they were generally safe. Many of their wheelchairs were less than ideal for self-propulsion. However, these participants enjoyed being challenged to perform wheelchair skills. If these findings are representative, they may have implications for the wheelchair-provision process in the LTC setting.

Effect of seat height on manual wheelchair foot propulsion, a repeated-measures crossover study: part 1 - wheeling forward on a smooth level surface.

PURPOSE: To test the hypotheses that, during manual wheelchair foot propulsion forward on smooth level surfaces, lowering the seat height increases speed, push frequency and push effectiveness, and decreases perceived difficulty. MATERIALS AND METHODS: In a repeated-measures crossover study, 50 able-bodied participants used one foot to propel a manual wheelchair 10 m on a smooth level surface at 5 seat heights in random order, ranging from 5.08 cm below to about 5.08 cm above lower-leg length. We recorded Wheelchair Skills Test (WST) capacity scores and used the Wheelchair Propulsion Test (WPT) to calculate speed (m/s), push frequency (cycles/s) and push effectiveness (m/cycle). We also recorded the participants' perceived difficulty (0-4) and video-recorded each trial. RESULTS: WST capacity scores were reduced at the higher seat heights. Using repeated-measures models (adjusted for age, sex and order), there were negative relationships between seat height and speed (p < 0.0001) and push effectiveness (p < 0.0001). Lowering the seat height by 5.08 cm below lower-leg length corresponded to improvements in speed of 0.20 m/s and in push effectiveness of 0.20 m/cycle. The trend for push frequency was also significant (p = 0.003) but the effect size was smaller. Perceived difficulty increased with seat height (p < 0.001). The video-recordings provided qualitative kinematic data regarding the seated "gait cycles". CONCLUSIONS: During manual wheelchair foot propulsion forward on smooth level surfaces, lowering the seat height increases speed and push effectiveness, and decreases perceived difficulty. CLINICAL TRIAL REGISTRATION NUMBER: NCT03330912.Implications for RehabilitationGenerally, wheelchairs used for forward foot propulsion should have a seat height that is 2.54-5.08 cm less than the sitting lower-leg length.Clinicians should, however, take into consideration other functions that may be adversely affected by lowering the seat height.

Effect of respiration on the static rear stability of wheelchairs.

OBJECTIVE: To test the hypothesis that the static rear stability of an occupied wheelchair is greater during full inspiration than expiration. DESIGN: Within-subject comparisons. SETTING: Rehabilitation center. PARTICIPANTS: Able-bodied participants (N=10). INTERVENTION: None. MAIN OUTCOME MEASURES: We measured the static rear stability (brakes unlocked) of an occupied wheelchair on a test platform according to International Organization for Standardization standards. We also used the Exhalation Threshold Test. The Exhalation Threshold Test was positive if, having been positioned at the maximum degree of platform tilt needed to maintain stability during full inspiration, the wheelchair tipped backward when the participant exhaled. RESULTS: The mean static rear stability values at full inspiration and expiration +/- SD were 16.5 degrees +/-2.3 degrees and 16.1 degrees +/-2.4 degrees , with a mean difference of .46 degrees +/-.24 degrees (3%; P=.002). The Exhalation Threshold Test was positive in 19 (95%) of 20 trials. CONCLUSIONS: Respiration has a slight but statistically significant effect on the rear stability of occupied wheelchairs, with greater stability at full inspiration. This has potential clinical implications for stability testing and the training of wheelchair skills, but further study is needed.

Ability of people with stroke to learn powered wheelchair skills: a pilot study.

OBJECTIVES: Our primary objective was to test the hypothesis that people with stroke can learn to use powered wheelchairs safely and effectively. Our secondary objective was to explore the influence of visuospatial neglect on the ability to learn powered wheelchair skills. DESIGN: Prospective, uncontrolled pilot study using within-participant comparisons. SETTING: Rehabilitation center. PARTICIPANTS: Inpatients (N=10; 6 with visuospatial neglect), all with a primary diagnosis of stroke. INTERVENTIONS: Participants received 5 wheelchair skills training sessions of up to 30 minutes each using the Wheelchair Skills Training Program (version 3.2). MAIN OUTCOME MEASURES: Powered wheelchair skills were tested before and after training using the Wheelchair Skills Test, Power Mobility version 3.2 (WST-P). RESULTS: The group's total mean WST-P scores improved from 25.5% of skills passed at baseline to 71.5% posttraining (P=.002). The participants with neglect improved their WST-P scores to the same extent as the participants without neglect, although their pretraining and posttraining scores were lower. The training and testing sessions were well tolerated by the participants, and there were no serious adverse events. CONCLUSIONS: Many people with stroke, with or without visuospatial neglect, can learn to use powered wheelchairs safely and effectively with appropriate training.

Practices and views of occupational therapists in Nova Scotia regarding wheelchair-skills training for clients and their caregivers: an online survey.

Purpose: To determine the extent to which Occupational Therapists (OTs) in Nova Scotia (NS) conduct wheelchair skills training, the nature of training and the OTs' perceptions on training.Materials and methods: Anonymous online survey.Results: We received 110 responses from OTs living in NS and involved in direct patient care, 96 (93%) of whom reported helping clients obtain manual wheelchairs. Of the OTs who responded to the question "…do you typically provide wheelchair-skills training…?", 40 (43.5%) answered "Yes, usually" for clients and 40 (46.0%) for caregivers. The median duration of training sessions for clients and caregivers was 30 and 20 min; the median number of sessions was 2 and 1. Regarding the importance of training, 65 (73.9%) OTs answered "Very important" and 22 (25%) "Somewhat important" for clients and 55 (64.0%) answered "Very important" and 29 (33.7%) "Somewhat important" for caregivers. About one-third of OTs considered themselves adequately prepared for the trainer role. A variety of barriers and facilitators to training were identified. Trainers were significantly more likely than non-trainers to consider wheelchair skills training as important (p = .0003 for clients and p = .0039 for caregivers) and to consider themselves adequately prepared for the trainer role (p = .002 for clients and .003 for caregivers).Conclusions: Only a minority of NS OTs usually provide wheelchair-skills training for clients or their caregivers and the training provided is minimal, despite a majority who consider such training to be important. Only about one-third of OTs feel prepared for the training role.Implications for rehabilitationOnly a minority of Occupational Therapists (OTs) in Nova Scotia, Canada usually provide wheelchair-skills training for clients or their caregivers.The training that is provided is minimal.A majority of OTs consider such training to be important.Only about one-third of OTs feel prepared for the training role.

Manual wheelchair-handling skills by caregivers using new and conventional rear anti-tip devices: a randomized controlled trial.

UNLABELLED: Kirby RL, Walker R, Smith C, Best K, MacLeod DA, Thompson K. Manual wheelchair-handling skills by caregivers using new and conventional rear anti-tip devices: a randomized controlled trial. OBJECTIVE: To test the hypothesis that, in comparison with caregivers handling manual wheelchairs equipped with conventional rear anti-tip devices (C-RADs), those using a new design (Arc-RADs) perform relevant wheelchair skills better and as safely. DESIGN: Randomized controlled trial. SETTING: Rehabilitation center. PARTICIPANTS: Caregivers (n=16) and the wheelchair users (n=16) for whom they cared. INTERVENTION: Participants were trained in wheelchair-handling skills for an average of 54 minutes each. MAIN OUTCOME MEASURES: Total percentage score on a set of 20 rear anti-tip device- and caregiver-relevant skills from the Wheelchair Skills Test, version 3.2, administered a minimum of 3 days after training. RESULTS: For the C-RAD and Arc-RAD groups, the mean +/- SD Wheelchair Skills Test scores were 40%+/-0% and 98.8%+/-3.5%, respectively (P<.001). Skills that required the wheelchair to be tipped back extensively (eg, for ascending a 15cm curb) accounted for the differences between the groups. There were no adverse effects in either group. CONCLUSIONS: The Arc-RAD design allows significantly better caregiver wheelchair-handling skills than the conventional design, without compromising safety.

Manual wheelchair tilt-rest skill: a cross-sectional survey of awareness and capacity among wheelchair users.

Purpose: The tilt-rest skill consists of tipping the wheelchair back and allowing it to rest against a solid object with the wheel locks applied (e.g., for pressure redistribution, neck comfort or hands-free activities). The objective of this study was to determine the proportion of experienced manual wheelchair users who are aware of this skill and who can perform it. Materials and methods: We conducted a cross-sectional survey of 49 manual wheelchair users using a questionnaire developed for the purpose. The tilt-rest skill was attempted by those who reported that they were capable of performing it. Results: Participants' mean (SD) age was 55.1 (18.2) years, 38 (77.6%) were male, their median (IQR) duration of wheelchair use was 2 (7.2) years and their mean (SD) daily time spent in the wheelchair was 9.5 (4.6) hours. Twenty-seven (55.1%) participants were aware of the skill, 19 (38.8%) reported being able to perform the skill and 16 of 47 (34.0%) were able to demonstrate the skill. Multivariate modelling with the question "Can you complete the tilt-rest skill?" as the dependent measure revealed an inverse relationship with age - Odds Ratio (95% Confidence Interval) of 0.476 (0.293, 0.774) (p = .0028) for each 10 year increase in age. Conclusions: Only just over half of manual wheelchair users are aware of the tilt-rest skill and one-third of users can perform it. Older people are less likely to report being able to complete the skill. These findings have implications for wheelchair skills training during the wheelchair-provision process. Implications for Rehabilitation Only just over half of manual wheelchair users are aware of the tilt-rest skill and only about one-third of users can perform it. Older people are less likely to report being able to complete the skill. These findings have clinical implications for wheelchair skills training during the, specifically that clinicians responsible for manual wheelchair-provision process should ensure that appropriate wheelchair users have the opportunity to learn this skill.

Development of Wheeled Mobility indicators to advance the quality of spinal cord injury rehabilitation: SCI-High Project.

Background: Wheeled mobility is critical for individuals with Spinal Cord Injury or Disease (SCI/D) related paralysis. The World Health Organization (WHO) developed guidelines highlighting eight steps in wheelchair service delivery: (1) referral and appointment; (2) assessment; (3) prescription; (4) funding and ordering; (5) product preparation; (6) fitting; (7) user training; and, (8) follow-up maintenance/repairs. This article describes the processes used to develop structure, process and outcome indicators that reflect the WHO guidelines within the Domain of Wheeled Mobility rehabilitation for Canadians. Methods: Wheeled mobility experts within the SCI-High Project Team used the WHO guideline to inform the Construct refinement and development of a Driver diagram. Following seven meetings, the Driver diagram and review of outcome measures and literature synthesis regarding wheelchair service delivery informed indicator selection and group consensus. Results: The structure indicator examines the proportion of SCI/D service providers within a rehabilitation program who have specialized wheelchair training to ensure prescription, preparation, fitting, and maintenance quality. The process indicator evaluates the average number of hours of wheelchair service delivery provided per patient during rehabilitation. The intermediary outcome indicator (rehabilitation discharge), is a target capacity score on the Wheelchair Skills Test Questionnaire (WST-Q). The final outcome indicators (at 18 months post rehabilitation admission) are the Life Space Assessment (LSA) and the Wheelchair Use Confidence Scale (WheelCon) short form mean scores. Conclusion: Routine implementation of the selected Wheeled Mobility structure, process and outcome indicators should measurably advance care within the Wheeled Mobility Domain for Canadians living with SCI/D by 2020.

Comparison between a tilt-in-space wheelchair and a manual wheelchair equipped with a new rear anti-tip device from the perspective of the caregiver.

OBJECTIVE: To test the hypothesis that, in comparison with a commercially available tilt-in-space wheelchair, a lightweight manual wheelchair equipped with a new, rear anti-tip device (Arc-RAD) provides caregivers with improved wheelchair-handling performance, less exertion, and greater satisfaction. DESIGN: Within-participant comparisons. SETTING: Rehabilitation center. PARTICIPANTS: Able-bodied participants (n=19) simulating caregivers and simulating wheelchair users (n=7). INTERVENTION: Caregiver participants were trained (50-75 min) in wheelchair-handling skills. MAIN OUTCOME MEASURES: Each participant was tested in both wheelchairs, in random order. To evaluate wheelchair-handling skills, we used the total percentage score on the Wheelchair Skills Test (WST), version 3.2. For exertion, we used a visual analog scale (in percent). For satisfaction, we used the Quebec Users' Evaluation of Satisfaction with assistive Technology (QUEST; range of values, 8-40), version 2. RESULTS: Mean percentage WST scores +/- SD for the Arc-RAD and tilt-in-space wheelchairs were 95.9%+/-4.2%, and 91.9%+/-4.8%, respectively (P=.008). The mean perceived exertions during Arc-RAD and tilt-in-space wheelchair use were 26.1%+/-20.4% and 46.6%+/-23.2% (P=.003). The mean total QUEST satisfaction scores for the Arc-RAD and tilt-in-space wheelchairs were 35.1+/-3.8 and 28.4+/-4.7 (P=.002). CONCLUSIONS: In comparison with the larger and heavier tilt-in-space wheelchair, a lightweight manual wheelchair equipped with a new rear anti-tip design allows 4.4% better wheelchair-handling performance, 44% less exertion, and 23.6% greater wheelchair satisfaction.

Wheelchair curb climbing: randomized controlled comparison of highly structured and conventional training methods.

OBJECTIVES: Our primary objective was to test the hypothesis that a highly structured training method for wheelchair curb-climbing requires less training time than conventional training. Our secondary objectives were to test the hypotheses that this training method increases success rate, reduces the need for spotter interventions, and reduces the participants' perceptions of difficulty. DESIGN: Randomized controlled trial. SETTING: Rehabilitation center. PARTICIPANTS: Able-bodied participants (N=16), randomly allocated to intervention (n=7) and control (n=9) groups. INTERVENTIONS: Both groups received up to 5 training sessions. Each session included instruction, practice, and feedback. The participants in the intervention and control groups used 18- and 9-step approaches, respectively. Training in the intervention group also included video demonstration, trainer demonstrations, mirror feedback, and standardized feedback phrases. MAIN OUTCOME MEASURES: Total training time, success rate at climbing a 15 cm-high curb, the number of spotter interventions during training, and a questionnaire. RESULTS: The mean+/-SD training times for the successful participants in the intervention and control groups were 42.5+/-24.4 minutes and 87.4+/-45.3 minutes (P=.084). The curb-climbing success rates of the intervention and control groups were 86% and 89% (P=1.000). There were no significant differences between the groups regarding the number of spotter interventions (P=.203) or for participants' perceptions of difficulty (P=.050). CONCLUSIONS: In comparison with a conventional method for curb-climbing, a highly structured method seems to require less than 50% of the training time for able-bodied participants, although this finding is only a trend statistically. This has implications for clinical training.
