For SCI subjects, leg wheeling with functional electric stimulation (FES) required less than half the effort (.18) of arm wheeling (.40).40
In the last series of experiments we evaluated electromyography (EMG) responses of the subjects' leg muscles during posture maintenance with different auditory noise conditions.
PLAC and POST were performed after the orthosis had been removed from the subject's leg.
Dynamic strength was assessed at weeks 0 and 24 as well as specific laboratory gait kinetics and kinematics during stepping over an obstacle and negotiation of a raised surface set at 10, 20 and 30% of each subject's leg length.
Briefly, for each subject, one leg was selected randomly to complete the protocol described below.
The facetectomy side was chosen according to the subject's leg pain symptoms.
Gravity correction was made by measuring resistance arm torque and subject's leg at full knee extension.
In this test measure, the proprioception deficit was calculated by the position error of subject's leg.
A metal ball with known radius, securely attached to each subject's leg or thigh, was used to calibrate the image of each frame.
Indeed the recommendation given in the literature is to establish foot preference by asking the subject which leg he or she would choose to kick a ball [ 31].
