The purpose of this RESNA Position Paper is to provide evidence from the literature and share typical clinical applications supporting the application of ultralight manual wheelchairs (ULWCs) to assist practitioners in decision-making and justification of wheelchair recommendations.

Manual wheelchair training approaches and intended training outcomes for adults who are new to wheelchair use: A scoping review

INTRODUCTION

Wheelchair training is pivotal for safety, independence, and occupational engagement in the community, yet adults coming into wheelchair use often receive insufficient or untailored training. This research aimed to understand the range and type of manual wheelchair training approaches that exist for adults commencing wheelchair use.

METHOD

A systematic scoping review involved searching eight electronic databases and grey literature up to September 2023. Papers relating to manual wheelchair training for adults and their caregivers were included for data extraction. Eighty-seven articles were included in this review. The International Classification of Functioning (ICF) was used to organise and analyse data related to intended training outcomes.

CONSUMER AND COMMUNITY INVOLVEMENT

Consumer consultation was not included in this review; however, the outcomes suggest that involving consumers in future wheelchair training research is critical to assure community participation outcomes.

RESULTS

Data were extracted from 87 papers. Manual wheelchair training was delivered across diverse contexts encompassing varied support structures, trainer backgrounds, and technology and was commonly directed towards wheelchair users with spinal cord injury. Intended training outcomes most frequently mapped to the activity and participation component of the ICF (n = 39), followed by personal factors (n = 27), body structures and functions (n = 18), and environmental factors (n = 3), with limited focus on longer term occupational engagement outcomes.

CONCLUSION

Most existing manual wheelchair training focussed on the acquisition of individual wheelchair skill and may not facilitate generalised and long-term occupational participation outcomes. Further exploration into the contexts that support occupational engagement, particularly for older adults with progressive conditions, is required to support service provision.

PLAIN LANGUAGE SUMMARY

We looked at what manual wheelchair training approaches exist for adults who need to use a manual wheelchair and what training helps people to do/achieve. We did a scoping review that looked at literature about manual wheelchair training programs for adult wheelchair users. We found 87 research papers and training programs that we included in our review. We recorded and analysed information from all the papers about the wheelchair training programs and outcomes for people who do these programs. We found that manual wheelchair training can be done in structured or ad hoc ways, can have different amounts of training, can be provided face-to-face or online, and can be given by different allied health professionals and other wheelchair users. Most training programs had short-term outcomes like learning manual wheelchair skills, being able to use the wheelchair properly, and feeling confident about using a wheelchair. Some had longer term outcomes about being able to use the manual wheelchair in everyday activities. Most people who did the training programs that we looked at in this review were manual wheelchair users with spinal cord injury. Because not many wheelchair programs have been tried with people who do not have a spinal cord injury, it is hard for occupational therapists to make recommendations about training for other people who use a manual wheelchair. Manual wheelchair training that is done in the community and made to meet the needs of individuals may help people with using their wheelchair for their everyday activities and participate in their community.

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: NCT04998539.

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.

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.

Measurement of self-propulsion distance of wheelchair using cycle computer excluding assistance distance by touch switch: A pilot study

Objective: Although the propulsion distance of a wheelchair is measured by some devices, measuring self-propulsion distance, excluding assistance propulsion distance by the caregiver, is difficult. This is a pilot study conducted to verify whether the propulsion distance of wheelchair users, excluding the assistance propulsion distance, can be measured using a cycle computer by attaching the touch switch.Methods: The wheelchair propulsion distance was measured using a cycle computer. We connected the touch switch and the cycle computer to the wheelchair to exclude assistance propulsion distance. We set the cycle computer to stop recording while the caregiver was touching the sensor. To confirm the propulsion distance using the cycle computer, the volunteer propelled the wheelchair on a rectangular facility with a total distance of 181 m, and the examiner confirmed the propulsion distance. The validation test to confirm the accuracy of the touch switch attached to the cycle computer was performed on a 50-m straight runway. The volunteer and caregiver propelled the wheelchair alternately by 10 m and continued until 50 m. The examiner confirmed the distance after 50-m propulsion.Results: In the 181-m rectangular facility, the propulsion distance that the volunteer propelled the wheelchair with the cycle computer was 180 m. In the 50-m straight runway, the propulsion distance was 30 m with caregiver assistance for 20 m.Conclusion: The present study showed that our modified device could measure the self-propulsion distance, excluding assistance propulsion distance in wheelchair users.

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.

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.

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.

A study on the effects of modified wheelchair skills program (WSP) for hemiplegic clients

The purpose of this study was to evaluate the modified WSP for improving wheelchair skills capacity, perceived satisfaction and performance in daily activities for hemiplegia patients in Korea. The modified WSP was tailored to better fit the environment and the treatment needs of hemiplegic patients in Korea. The resulting training procedure was augmented to help hemiplegic patients understand the basic mechanics of the wheelchair. To assess the efficacy of the modified WSP, 24 hemiplegic patients were selected as subjects and WST, COPM, K-MBI, and subjective opinion surveys were utilized. The results of the training showed significant improvement of WST, COPM, K-MBI scores in the experimental group and especially, the WST and COPM score showed statistically insignificant improvement compared to the control group. A modified WSP may prove effective for hemiplegic patients who exhibit low volition or are experiencing wheelchair use for the first time.

Cross-cultural adaptation of wheelchair skills test (version 4.3) for wheelchair users and caregivers to the Portuguese language (Brazil)

Objective: To perform cross-cultural adaptation of the Wheelchair Skills Test of manual wheelchair users and their caregivers into the Brazilian Portuguese language.Methods: The study was composed of translation, synthesis of translations, back-translation, review by an expert committee and pre-test, when the test was applied in the target population. Included were translators, subject specialists and coordinators to carry out the cross-cultural adaptation process, and manual wheelchair users and their caregivers with at least six months of wheelchair experience for the pre-test.Results: Forty-three people participated in the study, 30 for the pre-test and 13 for the stages that preceded the pre-test. The mean age of manual wheelchair users was 40.2 (±10.7) years and of caregivers was 44.2 (±15.7) years. Of the 47 phrases translated in the first stage, 36 discrepancies were found and resolved. During the analysis by the committee of experts the instrument underwent 13 modifications in order to achieve the best possible equivalence between the original version and the final version and was understandable by the people evaluated. The total pre-test scores of wheelchair users and their caregivers were 66.2 (±24.6) and 88.7 (±14.2), respectively.Conclusions: This instrument was able to evaluate the abilities of wheelchair users and their caregivers in Brazil, as well as being useful for training in rehabilitation programs.Implications for rehabilitationThe need to use wheelchair (WC) properly has made clinicians and rehabilitation professionals more concerned with assessing and training users' abilities with their WC.Cross-cultural adaptation allows for the linguistic modification of the original language of the evaluation tool into a new language and enables the comparison of research results in different countries.Immediate use of the instrument for WC users and caregivers in Brazil, both for evaluation and for training, is necessary and may be a means for rehabilitation professionals to improve their evaluations, their treatments and optimize the skills that aim at independence.

Wheelchair skills training for occupational therapy students: comparison of university-course versus "boot-camp" approaches

Objective: To test the hypothesis that occupational therapy students who receive wheelchair skills training education using a distributed-practice university-course approach versus a condensed-practice boot-camp approach results in greater improvements post-intervention in relevant outcomes. Design: A quasi-experimental, nonequivalent control group design. Setting: A university occupational therapy program. Participants: Occupational therapy students (experimental group) and recent occupational therapy graduates (control group) (N = 58). Interventions: A 15-week, 45-hour wheelchair provision course in which a total of 24 hours were dedicated to wheelchair skills testing and training education (experimental group) versus an 8-hour wheelchair skills training boot-camp (control group). Main outcome measures: Assessments were conducted pre- and post-intervention using the Wheelchair Skills Test Questionnaire (WST-Q), Wheelchair Use Confidence Scale for Manual Wheelchair Users (WheelCon) and Self-Efficacy on Assessing, Training and Spotting wheelchair skills (SEATS). Results: Compared to baseline, the WST-Q, WheelCon and SEATS scores improved significantly for both groups (p < .001). There were no significant differences in change scores (post-intervention - baseline values) between the groups for WST-Q, WheelCon or SEATS scores, however, the experimental group demonstrated a trend (p < .051) of higher scores for all outcome measures. Conclusions: Occupational therapy students who received wheelchair skills training using either a distributed-practice university-course or condensed-practice boot-camp approach demonstrated significant post-training improvements in their WST-Q, WheelCon and SEATS scores, but no significant differences were found between groups. Implications for Rehabilitation Both a distributed-practice university-course approach and a condensed-practice bootcamp approach for training wheelchair skills to occupational therapy students results in large post-intervention improvements in wheelchair skill, wheelchair confidence and self-efficacy to test, train, spot and document wheelchair skills. The pre-education (optional course) wheelchair skill, wheelchair confidence and self-efficacy to test, train, spot and document wheelchair skills scores found in this cohort of occupational therapy students confirms the need to include this wheelchair content in mandatory occupational therapy curricula.

A randomized control trial feasibility evaluation of an mHealth intervention for wheelchair skill training among middle-aged and older adults

BACKGROUND

Providing mobility skills training to manual wheelchair (MWC) users can have a positive impact on community participation, confidence and quality of life. Often such training is restricted or not provided at all because of the expense of, and limited access to, occupational and physical therapists before and after discharge. This is particularly true among middle-aged and older adults, who often have limited access to rehabilitation services and require more time to learn motor skills. A monitored MWC skills training home program, delivered using a computer tablet (mHealth), was developed as an alternative approach to service delivery. The purpose of this study was to evaluate the feasibility of implementing this mHealth MWC skills training program among middle-aged and older adults.

METHODS

A 2 × 2 factorial design randomized controlled trial (RCT) was used to compare the mHealth intervention and control groups, with additional wheeling time as a second factor. Community-dwelling MWC users aged 55 and older, who had used their MWC for less than two years and propelled with two hands, were recruited. Feasibility outcomes related to process, resources, management and treatment criteria were collected.

RESULTS

Eighteen participants were recruited, with a retention rate of 94%. Mean (±SD) duration for the first and second in-person training sessions were 90.1 ± 20.5 and 62.1 ± 5.5 min, respectively. In the treatment group, 78% achieved the minimum amount of home training (i.e., 300 min) over four weeks and 56% achieved the preferred training threshold (i.e., 600 min). Trainers reported only seven minor protocol deviations. No tablets were lost or damaged and there was one incident of tablet malfunction. No injuries or adverse incidents were reported during data collection or training activities. Participants indicated 98% agreement on the post-treatment benefit questionnaire.

DISCUSSION

Overall, the study protocol enabled implementation of the intervention in a safe, efficient and acceptable manner. Participant recruitment proved to be challenging, particularly gaining access to individuals who might benefit. Resource issue demands were acceptable for administration of the intervention; data collection was more time-consuming than anticipated but could be reduced with minor revisions. Participant retention and home program treatment adherence was high; both participant and trainer burden was acceptable. Treatment group participants reported a positive experience and clinical benefits from training program. The findings suggest a full-scale RCT evaluating the clinical impact of the Enhancing Participation In the Community by improving Wheelchair Skills (EPIC Wheels) intervention is warranted, provided the recruitment issues are addressed through collaborative partnerships and active recruitment strategies.

Manual Wheelchair Skills Training for Community-Dwelling Veterans with Spinal Cord Injury: A Randomized Controlled Trial

OBJECTIVES

To test the hypotheses that community-dwelling veterans with spinal cord injury (SCI) who receive the Wheelchair Skills Training Program (WSTP) in their own environments significantly improve their manual wheelchair-skills capacity, retain those improvements at one year and improve participation in comparison with an Educational Control (EC) group.

METHODS

We carried out a randomized controlled trial, studying 106 veterans with SCI from three Veterans Affairs rehabilitation centers. Each participant received either five one-on-one WSTP or EC sessions 30-45 minutes in duration. The main outcome measures were the total and subtotal percentage capacity scores from the Wheelchair Skills Test 4.1 (WST) and Craig Handicap Assessment and Reporting Technique (CHART) scores.

RESULTS

Participants in the WSTP group improved their total and Advanced-level WST scores by 7.1% and 30.1% relative to baseline (p < 0.001) and retained their scores at one year follow-up. The success rates for individual skills were consistent with the total and subtotal WST scores. The CHART Mobility sub-score improved by 3.2% over baseline (p = 0.021).

CONCLUSIONS

Individualized wheelchair skills training in the home environment substantially improves the advanced and total wheelchair skills capacity of experienced community-dwelling veterans with SCI but has only a small impact on participation.

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.

New portable voice guidance device for the manual wheelchair transfer: a pilot study in patients with hemiplegia

PURPOSE

Older and/or cognitively impaired patients require verbal guidance to prevent accidents during wheelchair operation, thus increasing the burden on caregivers. This study aimed to develop a new portable voice guidance device for manual wheelchairs and examine its clinical usefulness.

METHOD

We developed a portable voice guidance device to monitor the statuses of wheelchair brakes and footrests and automatically provide voice guidance for operation. The device comprises a microcomputer, four magnets and magnetic sensors, speaker and battery. Device operation was assessed during the transfer from a wheelchair to bed six times per day over three days for a total of 90 transfers in five stroke patients (mean age: 79.6 years) who required verbal guidance to direct wheelchair operation. Device usability was also assessed using a questionnaire.

RESULTS

The device performed perfectly during all attempted transfers (100%). To ensure safety, the assessor needed to add verbal guidance during 33 of 90 attempted transfers (36.6%). Overall, the device usability was favourable. However, some assessors were unsatisfied with the volume of the device voice, guidance timing and burden reduction.

CONCLUSIONS

Our device could facilitate wheelchair operation and might potentially be used to reduce fall risk in stroke patients and the burden on caregivers. Implications for Rehabilitation The acquisition of transfer independence is an important step in the rehabilitation of patients with mobility issues. Many patients require supervision and guidance regarding the operation of brakes and footrests on manual wheelchairs. This newly developed voice guidance device for manual wheelchair transfers worked well in patients with hemiplegia and might be helpful to reduce the fall risks and the burden of care.

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.

Development and evaluation of one-hand drivable manual wheelchair device for hemiplegic patients

This study was conducted for one-hand users including hemiplegic clients currently using standard manual wheelchairs, so as to analyze their specific problems and recommend solutions regarding usage. Thirty hemiplegic clients who were admitted to rehabilitation and convalescent hospitals participated as subjects. The research tools were standard manual wheelchairs commonly used by people with impaired gait and a "one-hand drivable manual wheelchair," which was developed for this study. The Wheelchair Skills Test (WST) was adopted for the objective assessment tool, while drivability, convenience, difference, and acceptability were developed for the subjective evaluation tools. The assessment procedures comprise two phases of pre-assessment and post-assessment. In the pre-assessment phase, the WST and subjective evaluation (drivability, convenience) were conducted using the existing standard manual wheelchair and with/without use of a foot to control the wheelchair. In the post-assessment phase, the WST and subjective evaluation (drivability, convenience, difference, acceptability) were also carried out using the developed one-hand drivable manual wheelchair. The results showed that the highest pass rate recorded for the WST items was 3.3% when the participants drove standard manual wheelchairs without the use of either foot and 96.7% when using the manual wheelchairs equipped with developed device. As compared to the existing wheelchair, statistical results showed significant effects on the WST, drivability, convenience, difference and acceptability when the participants drove wheelchairs equipped with the developed device. These findings imply that the one-hand drivable wheelchair equipped with the developed device can be an active and effective solution for hemiplegic clients using existing manual wheelchairs to increase their mobility and occupational performance.

Randomized controlled trial protocol feasibility: The Wheelchair Self-Efficacy Enhanced for Use (WheelSeeU)

BACKGROUND

Manual wheelchairs (MWCs) can improve mobility and social participation for individuals who experience difficulty walking; however, older adults receive little training for wheelchair use. The Wheelchair Self-Efficacy Enhanced for Use (WheelSeeU) research program provides peer-led training that may positively influence wheelchair use while reducing clinician burden.

PURPOSE

The purpose of this study is to evaluate the feasibility and clinical outcomes of WheelSeeU.

METHOD

A randomized control trial (RCT) recruits and randomly assigns 40 MWC users (55+ years). Feasibility indicators assessing process, resource, management, and treatment issues are measured, and clinical outcomes (wheelchair skills, safety, confidence, mobility, social participation, quality of life, health utility) are collected at three time points.

IMPLICATIONS

WheelSeeU provides an innovative approach for teaching wheelchair skills to an aging population that may improve wheelchair use and decrease clinician burden. Since RCTs are expensive and challenging in rehabilitation, establishing feasibility prior to larger effectiveness trials is prudent.

Evidence-Based Strategies for Preserving Mobility for Elderly and Aging Manual Wheelchair Users

Elderly and aging manual wheelchair (MWC) users have increased risk for accelerated loss of function and mobility that greatly limits independence and affects quality of life. This review paper addresses important issues for preserving function and mobility for elderly and aging individuals who use a MWC by presenting the current available evidence and recommendations. These include recommendations for maximizing function, by decreasing pain, improving the ability to self-propel, and prolonging mobility and endurance through ergonomics, individualized wheelchair selection and configuration, and adaptations for increasing the capacity to handle the daily mobility demands through training, strengthening, and exercise. Each recommendation is supported by current research in each relevant area.
