Predictive model of proficiency in powered mobility of children and young adults with motor impairments

Effectiveness of wheeled mobility skill interventions in children and young people with cerebral palsy: A systematic review

AIM

To systematically review the effectiveness of wheeled mobility interventions in children and young people with cerebral palsy (CP).

METHOD

A systematic literature search was performed in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, EBSCO, PEDro, and Web of Science using database-specific concepts such as 'child' and 'wheelchair'. Studies focusing on wheeled mobility skill interventions with participants aged 6 to 21 years with CP were included.

RESULTS

Twenty studies with 203 participants were included. The impact of wheeled mobility skill interventions was assessed on mobility skills (n = 18), activity and participation (n = 10), and quality of life (n = 3). No studies reported effects on stress, fatigue, and motivational aspects. Interventions included power wheelchair skill training (n = 12), computer-based training (n = 5), smart wheelchair training (n = 2), and manual wheelchair training (n = 1), showing positive wheeled mobility intervention effects. Study quality based on the Methodological Index for Non-Randomized Studies scale was 9 out of 16 and 14 out of 24 for non-comparative and comparative studies respectively. Risk of bias was serious-to-critical on the Risk of Bias in Non-Randomized Studies of Interventions.

INTERPRETATION

Wheeled mobility interventions showed promising beneficial effects on wheeled mobility, activity and participation, and quality of life for children and young people with CP. Future studies with structured and standardized training programmes and assessment tools are warranted to further accelerate the wheeled mobility skill acquisition process in this population.

WHAT THIS PAPER ADDS

Wheeled mobility interventions improve wheeled mobility skills in individuals with cerebral palsy. The mobility skill acquisition process benefits from structured and standardized training. Knowledge of the intervention effects on participation and quality of life is limited. Most studies had moderate quality of evidence because of methodological limitations.

Lessons learned from a pediatric powered mobility lending program

PURPOSE

To evaluate children's characteristics and impact of a powered wheelchair lending program including comparisons of diagnostic sub-groups, and validation of a predictive model of powered mobility proficiency.

METHODS AND MATERIALS

This retrospective study included 172 children who participated in the ALYN powered mobility lending program from 3/2009-7/2022. Demographics and functional levels were measured via questionnaires; driving proficiency was evaluated when the wheelchair was returned, and parents and children were interviewed following their participation in the program.

RESULTS

Two diagnostic groups were identified: cerebral palsy (CP) (n = 136, median = 9.75 yrs) and other neuromuscular diseases (NMD) (n = 30, median = 5.83 yrs). They differed significantly in the age they commenced PM training, the male/female ratio, walking ability and access mode. Fifty-seven percent of the participants with CP achieved powered mobility proficiency, a rate that was significantly lower than the 73% proficiency found for the NMD group. Four significant predictors were identified: communication, manual wheelchair operation, access mode and go-stop upon request. They predicted proficiency in approximately 80% of cases. Overall feedback from the parents and children indicated that their personal and family's quality of life improved as a result of their child's ability to use a powered wheelchair.

CONCLUSIONS

A lending program provides children with opportunities to improve mobility skills in an appropriate powered wheelchair. Children who can communicate verbally, propel a manual wheelchair, use a joystick and go-stop upon request are significantly more likely to become proficient drivers; however, many who were unable to complete these tasks also improved and even became proficient drivers.

Pediatric powered mobility training: powered wheelchair versus simulator-based practice

METHOD

Participants included 30 children and adolescents (23 males, 13 females) with cerebral palsy and other neuromuscular diseases, aged 6-18. Data were collected and compared at baseline and after 12 weeks of home-based practice via a powered wheelchair or a simulator. Powered mobility ability was determined by the Powered Mobility Program (PMP), the Israel Ministry of Health's Powered Mobility Proficiency Test (PM-PT) and the Assessment of Learning Powered Mobility (ALP).

RESULTS

All participants practiced for the required amount of time and both groups reported a similar user experience. Both groups achieved significant improvement following the practice period as assessed by the PMP and PM-PT assessments, with no significant differences between them. A significant improvement was found in the ALP assessment outcomes for the powered wheelchair group only.

CONCLUSIONS

This is the first study, to our knowledge, that compares two different wheelchair training methods. Simulator-based practice is an effective training option for powered mobility for children with physical disabilities aged 6-18 years old, demonstrating that it is possible to provide driving skill practice opportunities safe, controlled environments.

Evaluating a Therapeutic Powered Mobility Camp for Children with Severe Cerebral Palsy

Background. Children and youth with severe cerebral palsy (CP) have limited independent mobility, which affects opportunities for overall development. Purpose. To examine the effectiveness of Power Fun, a therapeutic powered mobility summer camp. Methods. A quasi-experimental, repeated-measure design was used, with participants acting as their own control. Twenty-four participants with severe CP (aged 7-20 years) attended Power Fun for three weeks, five days/week. Assessments of powered mobility skills and functional mobility goals were conducted three weeks before the camp (T1), at baseline (T2), postintervention (T3), and at three-week follow-up (T4). Findings. An analysis of variance results indicated significant improvements in powered mobility skills (F(1,22) = 56.61, p < 0.001, η²_p = 0.74) and functional mobility goals (F(1,58) = 80.17, p < 0.001, η²_p = 0.74), with 70% of goals achieved postintervention. A descriptive analysis revealed three learning profiles. Implications. This study provides initial evidence supporting the effectiveness of Power Fun as an intervention promoting powered mobility for children with severe CP, across a range of abilities.

Exploring change in young children's power mobility skill following several months' experience

PURPOSE

To measure and compare progression in children's power mobility skill among process and task-based measures following a loan of one of four early power mobility devices. Additionally, to explore different power mobility learner groups and skill development trajectories.

METHODS

In this pre-post study, children were purposefully sampled and power mobility skill was measured from video taken pre-post several months' experience (mean 192.40; SD 42.79 days) using the Assessment of Learning Powered mobility use (ALP) and two task-based measures. Associations among power mobility skill measures were examined. Child and environmental factors influencing ALP phase at loan-end were explored.

RESULTS

Forty-six children aged 13 - 68 months (mean 40.40; SD 15.60) participated, with cerebral palsy being the most common condition (n = 33; 71.74%). ALP change scores ranged from -2 to +4 ALP phases (median 1.0). Wilcoxon signed rank test was significant for pre-post differences with a large effect size (z = 5.50, p < 0.001; r = 0.57). End-of-loan Spearman correlations between ALP and two task-based paediatric measures were excellent (r_s = 0.92). Kruskal-Wallis test revealed significant effect of device, access method, diagnostic group and communication abilities on loan-end ALP phase.

CONCLUSION

Positive change was demonstrated with most children (n = 39; 84.78%) changing at least one ALP phase during the study. Positive change was seen with children at all phases of tool-use, using all devices and access methods. Process and task-based measures were highly correlated, but differed in application for different learner groups. Different trajectories of skill development may be associated with different child profiles and access abilities.IMPLICATIONS FOR REHABILITATIONChildren at all phases of tool-use can demonstrate positive change in power mobility skill using different devices and switch as well as joystick access methodsThe Assessment of Learning Powered mobility use (ALP) is useful for assessing tool-use and learning process skills for young children across the power mobility skill continuum.Task-based measures may also be helpful for guiding training and recording progress; The Power Mobility Training Tool (PMTT) is most useful for children exploring cause-effect and direction (ALP Phases 1-5), while the Power Mobility Program (PMP) is most useful for functional learners and those progressing from exploring direction to functional use (ALP Phases 5-8).Access method may influence power mobility learning trajectory and training.
