Exploring powered wheelchair standing device use in children and adults: a longitudinal case series.

PURPOSE
The purpose of this case series was to explore the influence of powered wheelchair standing device (PWSD) use on participants': (1) activities and participation; (2) quality of life; and (3) lower extremity passive range of motion (LE PROM).


CASE DESCRIPTION
Eight participants enrolled in the case series (five adults and three children). Outcome measures included: the Canadian Occupational Performance Measure (COPM), the EQ-5D-5L or the EQ-5D-Y, the Patient-Assessment of Constipation Quality of Life Questionnaire (PAC-QOL), LE PROM measurements and PWSD use data automatically collected by each PWSD. Participants were provided with a front wheel-drive PWSD designed for both outdoor and indoor use for up to 12-months of use.


OUTCOMES
Four participants completed the 12-month case series. Three participants achieved clinically significant improvements in performance on the COPM. Three of the four participants reporting issues with constipation achieved clinically significant improvements in their total PAC-QOL scores. Almost all participants demonstrated changes in some LE PROM.


CONCLUSIONS
Applying the Human Activity Assistive Technology model may help to explain differences in both PWSD use and outcomes amongst the individual participants in this case series. The participants who were most successful in using the PWSD were in environments with sufficient space to use the PWSD to perform everyday activities and had higher frequencies of PWSD use. The outcomes of this case series may assist both researchers and clinicians when implementing future PWSD studies recommending PWSDs to their clients/patients. Implications for rehabilitationA wide variety of factors may influence powered wheelchair standing device (PWSD) use.PWSD use may lead to improvements in activities, participation, quality of life and lower extremity passive range of motion.The participants who were most successful in using the PWSD were in environments that permitted use of the PWSD during the performance of everyday activities.COVID-19 restrictions prohibited in-person sessions with a therapist, which could have assisted participants in better integrating the PWSD in their daily lives.
