A pressure sensor-based exergame improved balance and mobility in a single-arm pilot (n=15) but showed no significant primary outcomes in a parallel-group randomised pilot (n=31) of low-income older adults receiving public community care.
A pressure sensor-based exergame improved balance and mobility in a single-arm pilot (n=15) but showed no significant primary outcomes in a parallel-group randomised pilot (n=31) of low-income older adults receiving public community care.
What they did
Two sequential pilots in low-income older adults receiving public community care: a single-arm study (n=15) and a parallel-group randomised pilot (n=31, mean age 81.5).
What they found
The single-arm pilot showed improvements in balance and mobility; the randomised pilot showed no significant primary outcomes.
What it actually shows
Two sequential studies: pilot single-arm (n=15, pre-post only) and pilot RCT (n=31, 84% female, mean age 81.5). Single-arm showed FDR-corrected improvements in balance and mobility; RCT showed no FDR-corrected primary outcomes. Hypothesis-generating only; adequately powered trials needed.

Where it fits
A clean illustration of why single-arm results need a control group before anyone believes them. Feasibility looks established here; efficacy does not.
