The Immediate Effects of Different Types of Augmented Feedback on Fast Walking Speed Performance and Intrinsic Motivation After Stroke.

PMID 37312981WHAT IT FOUND
All three feedback types produced small, non-significant increases in fast walking speed.
The full VR-exergame yielded the highest interest and enjoyment scores, but this difference did not survive correction for multiple comparisons.
Key findings
01Fast walking speed increased slightly with all feedback types, but the overall effect was not statistically significant.
02Intrinsic motivation scores were highest with the VR-exergame, but the difference from the no-VR condition was not significant after Bonferroni correction.

What it does not show
Very small sample size (n=18) limits generalizability. All outcomes were measured in a single session, so it is unknown if these immediate effects persist or accumulate over time. The study was underpowered to detect small differences, as evidenced by the borderline results and loss of significance after multiple comparison corrections.
The easy way to misread this
Do not interpret the slight numerical increases in walking speed or the higher enjoyment scores as evidence that VR feedback is superior or clinically effective. The primary outcome was not statistically significant, and the motivation finding did not survive correction for multiple tests.
