Development of an Upper Limb Robotic Device for Stroke Rehabilitation

Stroke is the major cause of permanent adult disability worldwide. Often stroke affects the motor control of the upper limb, leading to difficulties in performing activities of daily living. Many hours are spent in resource-intensive therapy to regain functionality of the upper limb. In order to decrease the burden to therapists and increase access to rehabilitation, an upper limb rehabilitation robotic device was developed. Observations from therapists and an international survey of stroke therapists were conducted to understand general requirements of an upper limb rehabilitation device. These requirements were the basis of the mechanical design portion of the prototype. The prototype was evaluated with stroke therapists in a focus group. Although more iterations of design, testing and evaluation are needed, this project is a step in developing a lower cost, portable device to increase access to upper limb stroke rehabilitation.
