PMID 41331618WHAT IT FOUND
Stroke patients reported significantly lower perceived effort during FES-assisted cycling compared to traditional cycling at the same workload.
Cerebral blood flow increased similarly in both conditions, and cognitive benefits were inconsistent, with a potential advantage for FES on one attention task.
Key findings
01Perceived effort was significantly lower during FES-assisted cycling compared to traditional cycling at the same workload.
02Middle cerebral artery velocity increased during both cycling conditions, but there was no significant difference between FES-assisted and traditional cycling.
03Cognitive performance improvements were inconsistent, though a more pronounced benefit was observed on the Neutral Stroop task after FES-assisted cycling.

What it does not show
The sample size was small (n=15) and based on availability rather than power calculations for cognitive or physiological outcomes. The study was not powered to detect differences in cerebral blood flow or cognitive performance, which were exploratory secondary outcomes. Cognitive data were missing for some participants due to fatigue or inability to complete tasks. The contribution of FES to force production was not directly measured, so the exact mechanical assistance provided is unknown. The qualitative analysis was exploratory and not designed a priori, limiting the depth of patient experience data.
Declared interests
The study was supported by UGECAM Rhône-Alpes. No other conflicts of interest were reported.
The easy way to misread this
Do not assume FES-assisted cycling provides superior cognitive or cerebral blood flow benefits compared to traditional cycling. The primary finding was reduced perceived effort; the cognitive and physiological differences were either non-significant or inconsistent.
