Electrical stimulation shows no clear added benefit with blood flow restriction, review finds
A review of five randomized trials involving 174 people found no consistent added benefit from neuromuscular electrical stimulation (NMES) with blood flow restriction (BFR). Evidence was very uncertain, so the review did not establish that combining them improved strength or other outcomes.
A systematic review and meta-analysis compared blood flow restriction (BFR) training plus neuromuscular electrical stimulation (NMES) with BFR alone. It included five randomized trials with 174 participants in several different training and rehabilitation settings.1
The review found no consistent additional benefit from adding NMES to BFR. Only two trials with 52 participants contributed to the strength analysis, which the authors called exploratory and highly uncertain.1
Evidence certainty was very low across outcomes, and the review said the combination should not be treated as an evidence-based upgrade over BFR alone. For coaches, the review did not support presenting NMES as a proven improvement over BFR alone.1
