Exoskeleton

A wearable mechanical or robotic device that fits around a part of the body — typically the hand, arm, or leg — and provides powered movement assistance, resistance, or guided motion. In rehabilitation contexts, exoskeletons are used to support intensive, repetitive motor exercises for people recovering from stroke, spinal cord injury, or other neurological conditions that impair motor function. The devices can operate in passive mode (system-controlled movement) or active mode (responding to the user’s muscle signals detected via electromyography). Exoskeletons are also used as assistive devices for daily living, enabling people with motor impairments to perform tasks like gripping objects or walking.
