Efficacy of belt electrode skeletal muscle electrical stimulation on reducing the rate of muscle volume loss in critically ill patients: A randomized controlled trial.

OBJECTIVES: Belt electrode skeletal muscle electrical stimulation can induce muscle contraction of the whole lower body. This study examined the efficacy of belt electrode skeletal muscle electrical stimulation on reducing loss of muscle volume in critically ill patients.
METHODS: Intensive care unit patients were randomly assigned to control and electrical muscle stimulation groups. In both groups, early rehabilitation was administered from day 2 of admission. In the electrical muscle stimulation group, belt electrode skeletal muscle electrical stimulation was administered. Femoral muscle volume was evaluated with computed tomography on days 1 and 10.
RESULTS: Ninety-Four severely ill patients were included 47 patients were assigned to each group. Femoral muscle volumes of 16 control and 21 electrical muscle stimulation group patients were measured. For both groups, femoral muscle volume decreased significantly from day 1 to day 10 (p < 0.0001). The mean rate of muscle volume loss was 17.7% (standard deviation (SD) 10.8%) for the control group and 10.4% (SD 10.1%) for the electrical muscle stimulation group (p = 0.04). The score for stair-climbing of Barthel Index was significantly better in the electrical muscle stimulation group 3.9 (SD 4.0) than in the control group 1.5 (1.5) (p = 0.04).
CONCLUSION: Belt electrode skeletal muscle electrical stimulation has the potential to inhibit muscle volume loss in critical care.
