Acute Feasibility of Neuromuscular Electrical Stimulation in Severely Obese Patients with Obstructive Sleep Apnea Syndrome: A Pilot Study

Figure 1

Overview of the experimental design: two 20 min sessions of NMES (one per condition: multipath NMES versus conventional NMES) were completed in a random order, with a cross-over design. In both conditions, stimulation frequency was 50 Hz, pulse duration was 400 μs, and current intensity was self-determined at the maximal tolerable level. The two experimental sessions were separated by at least 48 h.
