Hand Assistive and Rehabilitative Orthotic Device
One of the most common of military injuries are musculoskeletal injuries (MSI), which are inflicted upon thousands of individuals through combat and occupational risks. In addition, there are several medical conditions (e.g., stroke, brachial plexus injuries, ALS, spinal cord injuries, etc.) that can lead to reduced hand function. The hands and arms of these individuals require treatment, assistance, and rehabilitation to restore function.
With funding from the Department of Defense’s (DoD’s) Defense Health Program (DHP), LTI and its partners from Worcester Polytechnic Institute (WPI), Debra Latour, OTR/L, are creating and functionally evaluating a low-profile, battery powered, lightweight, and aesthetic device that can provide actuation to the fingers to create functional grip strength. The device can be used outside the clinic to increase strength and range of motion to assist the user in accomplishing their activities of daily living (ADLs). The device provides a powered grip in two different modes: three jaw chuck and key grip. In the three jaw chuck mode, the thumb is supported by the device and the index and middle finger are assisted in creating the grip. In the key grip mode, the fingers are stationary and supported and thumb movement is assisted.
