Skeletal muscle structure and function in response to electrical stimulation in moderately impaired COPD patients.

Study Objective: To determine the structural and functional consequences of high-frequency neuromuscular electrical stimulation (hf-NMES) in a group of moderately impaired outpatients with chronic obstructive pulmonary disease (COPD).

Design: A prospective, cross-over randomized trial.

Setting: An university-based, tertiary center.
