Video is taken of the patient walking along the walkway.
This is done both from the front and from the side. Passive range of motion is assessed on an examination table in the lab. Lower extremity strength measurements are taken while seated and lying down using a hand-held dynamometer. Surface EMG electrodes are placed over the left and right rectus femoris, hamstring, tibialis anterior, and gastrocnemius muscles. If a fine-wire EMG is to be used, it is done by itself, after all other testing has been completed.
