Study conducted to design a fully adjustable armrest for adults with hemiplegia to improve functional return, reduce glenohumeral subluxation, and reduce pain in the hemiplegic upper extremity. Existing wheelchair upper extremity supports such as laptrays and armrests cause the elbow to act as the weight-bearing surface. Based on clinical evidence, the devices tend to immobilize the forearm and elbow, and torque the shoulder as the body moves. The prototype palm weight bearing armrest allows freedom of motion at the elbow, which should protect the shoulder from torque as the body moves. The configuration of the armrest is easily adjustable by a trained caregiver as the client’s upper extremity changes over time. The device was designed by researchers at the Rehabilitation Institute of Chicago in Illinois. Implications for prototype evaluations are discussed.
