AI in Powered Exoskeletons

A powered exoskeleton is a motorized frame worn on the body to assist selected movements such as standing and walking. Control systems may combine sensors, user commands, and programmed steps; some research explores machine-learning methods, but many commercial devices use predefined control logic rather than a general-purpose AI. The exact controller and intended use vary by model. In the United States, certain exoskeletons are regulated medical devices. FDA records show 510(k) clearance for the ReWalk 7 Personal Exoskeleton with specified indications. Clearance for that model does not apply to every exoskeleton or prove a particular AI function is safe for every user. A powered device may require prescription, clinical evaluation, fitting, training, a trained companion, and defined surfaces or walking conditions. A 2016 meta-analysis included 14 studies and 111 people with spinal cord injury. Many participants learned to ambulate without physical assistance after training, but the included studies were small and used specific devices and protocols. These findings do not mean the exoskeleton repairs spinal injury or restores normal unaided walking. Potential users should discuss medical eligibility, bone density, skin integrity, range of motion, cardiovascular factors, fatigue, fall risk, and realistic goals with a clinical team. A demonstration or research prototype is not the same as an available cleared device. The device’s current label and training program define the actual scope.
