Lessons learned while exploring the impact of movement-tracking feedback on the experiences of children with neuromotor disorders taking part in interactive home exercise programs: a multi-case mixed methods study.

PMID 41761323WHAT IT FOUND
Movement tracking feedback helped two of three children complete more prescribed exercises, but the system often failed to count movements accurately.
Parents valued the feedback, while children found technical errors frustrating. The game was preferred over conventional home exercises, but the technology requires refinement before clinical use.
Key findings
01Exercise adherence was significantly higher with feedback for one child (p < 0.001) and numerically higher for another, but not for the third child (Bayesian factor favored no difference).
02No statistically significant difference in exercise fidelity (movement quality) was observed between feedback and no-feedback conditions for any of the three children.
03Movement tracking accuracy varied widely by exercise and environment, with errors exceeding the 25% acceptability threshold for several activities, leading to manual counting being used for analysis.

What it does not show
Only three participants were studied, preventing any generalizable conclusions about efficacy. Movement tracking was unreliable in home environments, requiring manual counting for analysis, which limits the real-world applicability of the automated feedback system. Self-reported ratings (smiley faces) were inconsistent and likely biased, with one child admitting to random selection. The study was stopped early to refine the technology, meaning the product tested is not the final version. Small sample size and unequal session counts violated some assumptions of the statistical tests used.
Declared interests
Funding was provided by multiple foundations and university awards, including the Azrieli Foundation, Margaret and Howard Gamble Research Grant, and Holland Bloorview Children's Foundation Chair in Pediatric Rehabilitation. The intervention was developed at Holland Bloorview Kids Rehabilitation Hospital.
The easy way to misread this
Do not interpret the improved adherence in one child as proof that movement-tracking feedback works. The system frequently failed to count exercises correctly, causing frustration, and the study was a preliminary pilot with only three participants designed to test the technology's usability, not its clinical effectiveness.
