An assembly of devices intended to be used in a clinical setting to provide non-gravity-compensating rehabilitation therapy for neuromuscular/musculoskeletal conditions affecting the back/trunk/limbs (e.g., impaired limb function) through patient interaction with a videogame-like display prompting repeated motion of a body part (e.g., arm, hand, leg) for functional improvement; it may also provide performance feedback. It does not provide weight support and is based on motion-sensing devices [e.g., battery-powered patient-worn infrared (IR) glove, motion tracking heel pad, movement tracking camera, software] that communicate wirelessly to provide a virtual-display interface.
