Résumé : |
Objective To compare maximal evoked torque, discomfort, and fatigue-related outcomes between multipath neuromuscular electrical stimulation (NMES) and conventional NMES of the quadriceps muscle in patients with total knee arthroplasty (TKA). Design Randomized, single-blind, crossover study with 2 experimental sessions (multipath NMES, conventional NMES). Setting Research laboratory. Participants Patients (N=20; mean age, 68y) 6 to 12 months after TKA surgery. Interventions None. Main Outcome Measures We quantified NMES-evoked knee extension torque at the maximally tolerated current intensity, self-reported discomfort, and fatigue induced by NMES intermittent contractions in both conditions. Results Compared with conventional NMES, multipath NMES resulted in higher evoked torque (33%, P<.001 lower discomfort scores p and less quadriceps muscle fatigue> Conclusions The use of multiple current pathways distributed to large electrodes allowed multipath NMES to generate stronger contractions and reduce discomfort and fatigue compared with conventional NMES. Therefore, multipath NMES has the potential to be more effective than conventional NMES. |
