HAL Hybrid Assistive Limb

The HAL (Hybrid Assistive Limb) is a wearable cyborg exoskeleton developed by Cyberdyne that uses bio-electrical signals (BES) from the wearer's muscles to detect movement intention and provide powered voluntary movement support. Unlike traditional exoskeletons that impose external motion, HAL works in harmony with the wearer's nervous system, supporting the patient's intended movement based on real-time bio-electrical feedback. Featuring Cybernic Voluntary Control and Cybernic Autonomous Control modes, HAL enables patients to actively participate in their rehabilitation while receiving robotic assistance at the hips, knees, and ankles.

With bio-electrical sensors detecting even muscle intention signals, HAL can support patients with severe paralysis who retain partial neural signal pathways to the muscles. The system is approved in Japan, EU, and other international markets for use in stroke, spinal cord injury, and neurodegenerative disease rehabilitation. For patients with limited mobility, HAL provides a patient-driven rehabilitation approach that promotes neuroplasticity and functional recovery through repeated voluntary movement practice. It represents a unique fusion of human intention and robotic assistance in modern rehabilitation medicine.
