Résumé : |
Objective To determine the stimulated strength of the paralyzed gluteal and paraspinal muscles and their effects on the seated function of individuals with paralysis. Design Case series with subjects acting as their own concurrent controls. Setting Hospital-based clinical biomechanics laboratory. Participants Users (N=8) of implanted neuroprostheses for lower extremity function with low-cervical or thoracic level injuries. Interventions Dynamometry and digital motion capture both with and without stimulation to the hip and trunk muscles. Main Outcome Measures Isometric trunk extension moment at 0°, 15°, and 30° of flexion; seated stability in terms of simulated isokinetic rowing; pelvic tilt, shoulder height, loaded and unloaded bimanual reaching to different heights, and subjective ratings of difficulty during unsupported sitting. Results Stimulation produced significant increases in mean trunk extension moment (9.2+9.5Nm, P<.001 and rowing force p over baseline volitional values. similarly stimulation induced positive changes in average pelvic tilt shoulder height during quiet sitting bimanual reaching increased mean reach distance all subjects target heights loading conditions. consistently rated tasks with easier than voluntary effort alone.> Conclusions In spite of considerable intersubject variability, stabilizing the paralyzed trunk with electrical stimulation can positively impact seated posture, extend forward reach, and allow exertion of larger forces on objects in the environment. |
