QUICK TAKE:** Higher durations of electrical stimulation do not lead to better movement outcomes in stroke patients

Our newest publication challenges conventional thinking on dosage in stroke rehabilitation.

We explored the impact of total time spent using EMG-triggered neuromuscular electrical stimulation (E-nMES) on motor recovery in stroke.

41 participants underwent two 40-minute sessions daily, 5 days a week, over 8 weeks.
Despite variations in total stimulation duration (average ~2347 minutes, range: 173–3773 minutes), all participants demonstrated significant improvements in motor function, as measured by Fugl-Meyer Upper Extremity (FMA-UE) and Arm Motor Ability Test (AMAT).
Notably, our analysis revealed NO CORRELATION between the total duration of stimulation and motor outcomes (FMA-UE: ρ = –0.072, p = 0.65; AMAT: ρ = 0.079, p = 0.62).

Key Insight:

Higher durations of electrical stimulation do not lead to superior movement outcomes.
