Key result
Cyclical electrical stimulation moderately increases immediate voluntary strength compared to sham or control.
Why the study?
Does electrical stimulation of the motor system improve voluntary strength and activity in adults with stroke?
Meta-Analysis (n=2,905)
Does electrical stimulation of the motor system improve voluntary strength and activity in adults with stroke?
Answers are grounded in this paper and cite their sources.
Electrical stimulation, particularly CES, moderately improves voluntary strength after stroke, while FES provides a small benefit in activity performance when added to standard practice.

Scrivener et al. (2025) conducted a meta-analysis in stroke (n=2,905). Cyclical electrical stimulation (CES) vs. Nothing/sham was evaluated on Voluntary strength immediately post-intervention (SMD 0.47, 95% CI 0.32 to 0.61). Cyclical electrical stimulation moderately increased voluntary strength immediately post-intervention compared to nothing or sham.
