Biomechanical automatic joint alignment for wrist rehabilitation exoskeleton

Biomechanical automatic joint alignment for wrist rehabilitation exoskeleton
Technology Benefits
The force and position control in the device enables it to have many functional possibilities, including
- Disability assessment (measure range of motion, strength, reaction time etc.)
- Games and entertainment during therapy (touch screen on control box, PC, iPad based etc)
- Haptic interface with gaming
- Rehab after sports injuries
- Force feedback and safety
- Strengthening exercises
- Assistance exercises
Technology Application
The technology has potential application in the medical market, in the fitness and high performance athlete industry, and in the military and aerospace industries.
The technology can be used:
• For strength, stretching and coordination training
• To diagnose and rehab an injury
• To sense when an injury is likely to happen
• To facilitate anatomically superior and targeted exercise vs. eg lifting weights against gravity
Application Date
Application No.
A robotic exoskeleton that can be worn by the user and that has a novel sensing mechanism which allows for speed and force control of human joints throughout exercise by using motors and a control system to vary resistance/assistance. The robotic healthcare device has a gaming interface and has potential applications in both the medical and high performance training fields. User data is collected by the sensors and can be used with personalised biomechanical models of the user to characterise the properties (strength, speed, endurance etc.) of each individual muscle. This data can be used to automatically assess, optimise and monitor progress of therapy or exercise plans delivered via the device.
The initial prototype device is a wrist rehabilitation device for patients with high muscle tone and/or wrist contractures as a result of a stroke, Cerebral Palsy or other disorders/injuries. It is intended that the device will provide assistive movement to stretch the patient’s wrist, both with and without patient input.
