A new multitasking exoskeleton can be used for any of an entire arm’s eight movements that originate from the shoulder, elbow, or wrist joints. Detachable parts allow the therapist to focus on a single joint or all of them at once.

The prototype offers features that are unavailable in current devices. Its modules are quickly assembled and customizable, meaning the device can be used for a wide variety of injuries or debilitation. Sensors provide therapists with range-of-motion information, and a session’s results are recorded so that PTs can monitor progress.

The exoskeletons include sensors and motors and use artificial intelligence. The combination informs the exoskeleton how much motion the patient is capable of, and it allows the device to automatically amplify a muscle’s weakened electrical impulse to make up the difference.
