Relationship between wheelchair skills scores and peak aerobic exercise capacity of manual wheelchair users with spinal cord injury: a cross-sectional study

Community mobility and participation assessment of manual wheelchair users: a review of current techniques and challenges

According to the World Health Organization, hundreds of individuals commence wheelchair use daily, often due to an injury such as spinal cord injury or through a condition such as a stroke. However, manual wheelchair users typically experience reductions in individual community mobility and participation. In this review, articles from 2017 to 2023 were reviewed to identify means of measuring community mobility and participation of manual wheelchair users, factors that can impact these aspects, and current rehabilitation techniques for improving them. The selected articles document current best practices utilizing self-surveys, in-clinic assessments, and remote tracking through GPS and accelerometer data, which rehabilitation specialists can apply to track their patients' community mobility and participation accurately. Furthermore, rehabilitation methods such as wheelchair training programs, brain-computer interface triggered functional electric stimulation therapy, and community-based rehabilitation programs show potential to improve the community mobility and participation of manual wheelchair users. Recommendations were made to highlight potential avenues for future research.

Association between individual wheelchair skills and fitness in community-dwelling manual wheelchair users with spinal cord injuries

PURPOSE

Wheelchair skills are a key component to promotion of community participation among persons with spinal cord injury (SCI). The objective of this secondary analysis was to examine the association between individual wheelchair skills from the Wheelchair Skills Test Questionnaire (WST-Q) and fitness among community-dwelling adults with SCI.

MATERIALS AND METHODS

Twenty-six adults were recruited to complete the WST-Q and a standard graded aerobic wheelchair exercise test on a motorized treadmill for assessing peak power output (POpeak).

RESULTS

Spearman Rho rank-order correlation (ρ) analyses indicated statistically significant correlations between POpeak and six basic (ρ = 0.41-0.57), eight intermediate (ρ = 0.44-0.59), and nine advanced (ρ = 0.42-0.80) WST-Q skill scores. After controlling for sex and injury level (Partial Spearman Rho rank order) significant correlations persisted for four advanced skills (i.e., descends high curb, turns in place in wheelie position, descends steep incline in wheelie position, descends high curb in wheelie position; ρ = 0.46-0.59) and one additional skill (i.e., ascends high curb ρ = 0.51).

CONCLUSIONS

More advanced wheelchair skills are significantly associated with fitness in persons with SCI. The directionality of the skills-fitness relationship, specifically whether wheelchair skills facilitate greater fitness or fitness is a prerequisite for certain wheelchair skills needs to be determined in future, larger studies. However, results from this study provide a comprehensive list of wheelchair skills that are associated with fitness that can be directly applied to guide further research and practice promoting community participation among persons with SCI.Implications for RehabilitationSignificant positive associations exist between advanced wheelchair skills (i.e., descends high curb, turns in place in wheelie position, descends steep incline in wheelie position, descends high curb in wheelie position and ascends high curb) and fitness in manual wheelchair users with spinal cord injury (SCI).This study provides a list of skills associated with fitness to guide clinical practice and areas for further rehabilitation research assessing the directionality of the relationship between fitness and wheelchair skills.

Home-based exergaming training effects for two individuals with spinal cord injury: A case report

INTRODUCTION

Exergaming is a type of serious game that requires active bodily movements for video gameplay. This game-based exercise is gaining interest as a form of leisure activity of moderate-vigorous dose intensity.

OBJECTIVE

This case report sought to assess the effects of exergaming training (i.e. Move Boxing, Move Tennis, and Move Gladiator Duel) on aerobic capacity, feasibility, enjoyment and motivation in two individuals with spinal cord injury (SCI).

CASE DESCRIPTIONS

Two males with SCI at the level of L4 and T10, aged 32 and 39, respectively, underwent home-based exergaming training sessions over a period of 12-18 weeks, conducted within moderate-vigorous intensity training zones for health improvements as recommended by health guidelines. Their peak oxygen consumption (VO₂), physical activity levels and perceived enjoyment were evaluated before, during and after the completion of the training.

OUTCOMES

Participant peak VO₂ improved (effect size g = 2.7) from their baseline values (Participant A: 16.0 ± 0.7 mL/kg/min to 41.7 ± 8.1 mL/kg/min; Participant B: 13.5 ± 0.8 mL/kg/min to 32.7 ± 5.2 mL/kg/min), with an increase in overall weekly physical activity levels. Both participants maintained a relatively high level of enjoyment scores throughout their training period (mean: 31.9 ± 3.2, p = .56, 95% CI 0.22-1.0).

CONCLUSION

A home-based exergaming training program improved aerobic capacity and level of physical activity, while maintaining adherence to the exercise within a relatively high perception of enjoyment for these two participants. The relatively high enjoyment scores maintained throughout the duration of the exergaming training period suggested its feasibility as a home-based exercise program and perceived as enjoyable by these individuals.

The effect of external power output and its reliability on propulsion technique variables in wheelchair users with spinal cord injury

The purpose of this study was to assess 1) how treadmill slope variance affected external power output (PO) and propulsion technique reliability; and 2) how PO is associated with propulsion technique. Eighteen individuals with spinal cord injury performed two wheelchair treadmill exercise blocks (0% and 1% treadmill slope, standardized velocity) twice on two separate days. PO, velocity, and 14 propulsion technique variables were measured. In a follow-up study, N=29 performed wheelchair treadmill drag tests. Target and actual slope were documented and PO, intraclass correlation coefficients (ICC) and smallest detectable differences (SDD) were calculated. Within and between visits, the reliability study ICCs were perfect for velocity (1.0), weak for PO (0.33-0.46), and acceptable (>0.70) for five (0% slope) and 10 (1% slope) propulsion technique variables, resulting in SDDs of 35-196%. Measured PO explained 56-90% of the variance in key propulsion technique variables. In the follow-up, PO ICCs were weak (0.43) and SDDs high. Bias between target and actual slope appeared random. In conclusion, PO variability accounts for 50-90% of the variability in propulsion technique variables when speed and wheelchair set-up are held constant. Therefore, small differences in PO between interventions could mask the effect of the interventions on propulsion technique.

The Effectiveness of Active Rehabilitation Camp on Physical Performance of Disabled People Moving in Wheelchairs

(1) Background: Regular participation in physical activity (PA) prevents many medical complications and improves the physical fitness of people with spinal cord injury, and in turn improves the functional independence, psychosocial status and quality of life. The goal of Active Rehabilitation Camps (ARCs) is to use various forms of PA in order for the participants to obtain the greatest efficiency and independence in everyday life. (2) Purpose: To evaluate the improvement in physical performance of people with chronic spinal cord disabilities moving in wheelchairs taking part in the Active Rehabilitation Camp depending on (a) sex, (b) type of disability, (c) the level of injury and (d) the type of wheelchair. (3) Methods: The study included 42 wheelchair users: 28 men and 14 women aged 18-65 years (34.7 ± 14.9 years) taking part in the Active Rehabilitation Camp. Finally, the study involved 27 paraplegics, 9 tetraplegics and 6 individuals with myelomeningocele. The participants took part in four fitness tests: (1) sprint test (SP)-individual time to cover a distance of 15 m in the wheelchair; (2) slalom test (SL)-time to ride between four cones front and back; (3) basketball ball throw at a distance (BT), (4) zig-zag test (ZZ)-riding continuously for 6 min on the designated track. The tests were performed at the beginning and at the end of the ACR. Active wheelchairs were used by 32 participants, and 10 participants used the classic wheelchairs. (4) Results: Paraplegics achieved the best average results in all the tests and the best improvement in physical performance in comparison to individuals with myelomeningocele and tetraplegics. People in active wheelchairs achieved a statistically significant improvement in the results of SL and ZZ (p < 0.001). People with injury above Th-9 level of the spinal cord achieved a statistically significant improvement in the results of SP (p < 0.01), SL and ZZ (p < 0.01). People with injury below Th6 achieved a statistically significant improvement (p < 0.05) in SP, SL and ZZ. (5) Conclusions: Regular PA during the Active Rehabilitation Camp improves the physical performance of disabled people in wheelchairs, but the scale of improvement of physical performance fitness depends on the type of wheelchair used and the level and the type of injury.

The effects of wheelchair mobility skills and exercise training on physical activity, fitness, skills and confidence in youth using a manual wheelchair

PURPOSE

To evaluate the effects of a combination of wheelchair mobility skills (WMS) training and exercise training on physical activity (PA), WMS, confidence in wheelchair mobility, and physical fitness.

METHODS

Youth using a manual wheelchair (n = 60) participated in this practice-based intervention, with a waiting list period (16 weeks), exercise training (8 weeks), WMS training (8 weeks), and follow-up (16 weeks). Repeated measures included: PA (Activ8), WMS (Utrecht Pediatric Wheelchair Mobility Skills Test), confidence in wheelchair mobility (Wheelchair Mobility Confidence Scale), and physical fitness (cardiorespiratory fitness, (an)aerobic performance) and were analysed per outcome parameter using a multilevel model analyses. Differences between the waiting list and training period were determined with an unpaired sample t-test.

RESULTS

Multilevel model analysis showed significant positive effects for PA (p = 0.01), WMS (p < 0.001), confidence in wheelchair mobility (p < 0.001), aerobic (p < 0.001), and anaerobic performance (p < 0.001). Unpaired sample t-tests underscored these effects for PA (p < 0.01) and WMS (p < 0.001). There were no effects on cardiorespiratory fitness. The order of training (exercise before WMS) had a significant effect on confidence in wheelchair mobility.

CONCLUSIONS

A combination of exercise and WMS training appears to have significant positive long-term effects on PA, WMS, confidence in wheelchair mobility, and (an)aerobic performance in youth using a manual wheelchair.Implications for rehabilitationExercise training and wheelchair mobility skills (WMS) training can lead to a sustained improvement in physical activity (PA) in youth using a manual wheelchair.These combined trainings can also lead to a sustained increase in WMS, confidence in wheelchair mobility, and (an)aerobic performance.More attention is needed in clinical practice and in research towards improving PA in youth using a manual wheelchair.
