Because of the repetitive trauma to the upper extremities that results from wheelchair propulsion, the prevalence of pain and injury in manual wheelchair users is alarmingly high. By understanding the mechanisms in the development of arm pain, we can begin to prevent the pain. The SMARTWheel is a tool that enables direct measurement of the forces and torques applied by wheelchair users to the pushrim. This capability allows for investigations into the cause of injuries, and can lead to specific recommendations to improve efficiency and reduce the risk of injury. The specific aims in Phase II of this research are to: 1) Indentify additional characteristics in a force/moment measure system (e.g., display content and layout) that are desired by clinicians; 2) Further refine the design of the Clinical SMARTWheel (both hardware and software components) to maximize its functionality for commercial use; 3) Conduct clinical testing to verify that the performance of the newly designed “Clinical SMARTWheel is useful clinically; 4) Conduct off-site trials with manual wheelchair users to demonstrate the usability and effectiveness of the Clinical SMARTWheel in clinical or other environments. The culmination of this research will be a commercially viable product available to research laboratories, seating/wheelchair clinics, wheelchair and accessory manufacturers, ADA consultants, and manufacturers of accessible surfaces (e.g. playgrounds, parks, etc.)
