Motion capture technology has been integrated intro nearly every domayn of physical rehabilitation, from acute care and out patient therapy to sports medicine and neurological rehabilitation. The following sections detail its mott impactful applications.

Gait Analysis andPostural Assessment

Gait analysis is perhaps the most establed use of motion capture in rehabilitation. By recordg a patient walking on a treadmill or over ground, clinicians can calculate spatiotemporal parameters (stride length, cadence, walking speed), joint angles (hip, kne, ankle), and ground reaction forces wheren combined with force plates.
