A robotic arm that can be worn at home is being developed to help stroke survivors regain the ability to grasp objects and perform basic tasks such as feed themselves.

The device, built by Arizona State University and Kinetic Muscles, can also assess the effectiveness of the physical therapy so adjustments can be made to the regimen if necessary.

Stroke survivors can recover significant use of their arms by performing repetitive motor function exercises over a period of time.
RUPERT I, for Robotic Upper Extremity Repetitive Therapy “is intended to provide cost-effective therapy to a wider population for a longer period of time for maximum recovery of motor function,” explained biomedical engineer Jiping He.

The device is powered by four pneumatic muscles and is movable at the shoulder, elbow and wrist. It is adjustable to accommodate different arm lengths and body sizes.

RUPERT II, a second generation prototype, is under development.
