Medical HAL Single Joint Type

Medical HAL Single Joint Type is the portable member of Cyberdyne's clinical range. Where the Lower Limb Type is a full leg exoskeleton wheeled up to a patient who can stand in a harness, this is a 1.5 kg brace clamped to one joint, which makes it usable in positions and places the larger device cannot reach — a hospital bed, an intensive care unit, a patient who cannot yet be stood up. The control principle is the same across the family: skin-surface electrodes read the faint bio-electrical signal that leaks out when the brain commands a muscle, and the motor assists the movement the wearer was already attempting. One unit covers four joints. Changing the attachment parts moves it between elbow and knee, which are supplied in the base package, and ankle and shoulder, which are optional kits sold separately. The powered range is extension 0 degrees to flexion 120 degrees, the battery runs about 120 minutes in normal operation, and the stated dimensions and weight cover only the parts worn on the body — the control unit and battery sit outside that figure, which is worth knowing before comparing it against exoskeletons quoted as complete systems. A dedicated monitor shows signal strength, a target repetition count and a comparison against previous sessions. The regulatory footing differs from that of the leg device, and the difference is easy to miss. HAL-SJ carries a CE mark under the older Medical Device Directive and is registered with the US Food and Drug Administration as a Class I device — registration, not the 510(k) clearance route the Lower Limb Type went through three times. As with every Medical HAL product, Cyberdyne requires clinicians to complete a structured safety training programme before use. The catalogue records 2014 as the year because the product page is documented from January 2014; the manufacturer does not publish a launch date.
