A finite element analysis of a commercial forearm crutch for children during gait is presented. The geometric features of the crutch structure were acquired and modeled. The finite element model was created using shell elements based on the frame surfaces. Linear elastic material properties for aluminum alloy were utilized. Upper extremity kinetic data from reciprocal and swing-through gait patterns...
Conventional underarm crutches have been ubiquitous for rehabilitation over the centuries. A disadvantage of the design is that they tend to unintentionally waste the users' energy and increase pain and discomfort. Insight to dynamical crutch walking reveals an optimized design principle that harnesses the dissipated energy arising from the interaction between the crutches, the ground and the user's...
This paper proposed a novel software evolution methodology CRUTCH that can rapidly integrate partners' Web services into internal agentified legacy system running on JADE. CRUTCH achieves this goal in two ways. On one hand, CRUTCH provides an architecture view that extends the standard FIPA's agent platform with a Web service finder agent named WSFinder; on the other hand, CRUTCH developed a package...
