BIOMECHANICAL ANALYSYS OF LOWER EXTREMITIES DURING CONVENTIONAL AND FUNCTIONAL ELECTRICAL STIMULATION (FES) ROWING IN NON-DISABLED INDIVIDUALS

摘要

Functional electrical stimulation (FES) rowing is a whole-body exercise in which the lower extremities are moved by electric stimulation and the upper extremities are moved voluntarily by paraplegics. The purpose of this study was to identify the kinematic factors of the lower extremities required to perform FES-rowing through the biomechanical analysis. Eighteen healthy adult men participated in this study. A mathematical model was developed to analyze the conventional rowing with or without handle and FES lower extremity extension exercise. During rowing with handle, maximum hip, knee extension and ankle plantar flexion moment was 23.5± 4.5 Nm (Mean±SD), 2.5±3.1 Nm, and 11.9±2.5 Nm. During rowing without handle, maximum hip, knee extension and ankle plantar flexion moment was 8.0±3.9 Nm, 4.1±4.0 Nm, and 7.9±2.6 Nm. During FES lower-extremity extension exercise, maximum hip, knee extension and ankle plantar flexion moment was 4.7±2.7 Nm, 4.8±2.9 Nm, and 7.5±1.8 Nm. The calculated data has the potential to be applied in the low-load and safe FES rowing exercise for the paraplegics.
