Clinical Reliability of a Device for Measuring Forces and Moments in Amputee Gait
MetadataShow full item record
Practitioners find it difficult to measure forces and moments on a prosthesis when an amputee walks. Traditional measures, such as using force platforms, are expensive and inaccessible. Practitioners also question the applicability of lab measurements to everyday activities. The iPecs is a portable device that measures forces and moments on a prosthesis. The device demonstrates reliable data over multiple gait speeds and over two testing days (r > 0.9). The iPecs captures characteristic gait data similar to a force platform; however, variations occur due to different coordinate reference planes and the stiffness of the prosthetic foot. Compared to a force platform, iPecs captures more data in less time and fewer overall steps. Portability of the iPecs allows use in daily activities, outdoors, or in clinic, making it an alternative to traditional methods of measuring kinetic data.
