The Next Challenge in ProstheticsBy Boone, David; Rehab Management,
Publication Date: July 2009
Article describes an electronic device for use in prosthesis alignment. The Computerized Prosthesis Alignment System: ComPAS provides computerized, real-time gait analysis with socket reaction force measurements, adding a multi-axial force sensor to most lower-limb prostheses and smart software that helps the prothetist to see and interpret deviations in the dynamic balance of the prosthesis. Application of the gait-alignment device is similar to assembling any standard modular prosthesis system and is compatible with most modular prostheses regardless of manufacturer. Using the technology, the prosthetist receives consistent measurement and automated analysis of gait via user-friendly indicators. Feedback is presented in concise language. Instructions for adjusting the modular system alignment screws are simple and explicit. Specially-designed graphs provide “socket reactions,” information on how the socket is pushing back against the limb during the gait cycle. By relying on direct measurement of the forces of walking with a prosthesis, ComPAS detects differences between alignment conditions that may not be observable in movement patterns exhibited by the patient during a traditional observational gait analysis process. With the technology, the final alignment of the prosthesis is recorded electronically for the clinical record of the patient.
