PMID 41767111WHAT IT FOUND
Objective feedback on shoulder movement improved exercise motivation for one month in older adults with stroke, diabetes, or foot deformity.
Motivation dropped off after four weeks. The effect was absent in participants with Parkinson's disease, who declined regardless of feedback.
Key findings
01Feedback group showed increased motivation to participate and continue exercising at four weeks, while the control group did not.
02Participants with Parkinson's disease had significantly lower motivation scores regardless of whether they received feedback.
03The positive effect of feedback on motivation diminished after one month, indicating the need for continuous feedback.

What it does not show
The study used a non-randomized design with a very small sample size (n=31), limiting causal inference. The feedback intervention was only effective for one month; motivation declined significantly by week eight. Participants with Parkinson's disease were excluded from the main analysis because they showed negative trends, meaning the findings do not apply to this common rehabilitation population. The control group received feedback at the end of the study, which may have influenced their post-intervention responses. The outcome measure was a simple three-question survey, not a validated standardized tool.

The easy way to misread this
Do not interpret the one-month improvement in motivation as evidence that AI feedback sustains long-term adherence. The benefit vanished by week eight, and the effect was entirely absent in patients with Parkinson's disease, who declined regardless of intervention.
