A patient's gait can be monitored while a video camera attached to a computer captures the gait cycle in real time while walking or running on a treadmill. The video can be played back frame by frame, illustrating each phase of the gait cycle. This allows our trained experts to analyze a person's gait for diagnosing biomechanical abnormalities in foot, leg, hip or back function. The motion analysis may also be used as a tool for analyzing a patient with a corrective device in their shoes to determine the effectiveness of the foot orthotic device.
