CEU Course Description
People with a lower-extremity amputation encounter a series of stress-related challenges during walking such as greater forces on their unaffected leg, and may thus be predisposed to secondary musculoskeletal injuries. The first aim of this CEU course is to examine the effects of an adaptation period on stride-to-stride fluctuations in both the sound leg and prosthetic leg following receipt of a new prothesis. This is seen in a randomized crossover design study with 24 individuals with below knee amputation (BKA) and compares different prosthetic designs based on functional classifications. The second section of the course examines the changes in gait characteristics of transtibial amputees with different suspension systems comparing the MPSS, pin/lock and Seal-In suspension systems with a newly designed suspension system looking at kinetic and kinematic variables, pistoning, and gait deviations. The next section determines the kinetic effects and ground reaction forces of a powered ankle-foot prosthesis on the unaffected leg of people with a unilateral transtibial amputation over level ground across the full range of walking speeds compared to a more conventional passive-elastic traditional component. Finally, we will determine if muscle activation signals could be recorded from residual lower limb muscles within the prosthetic socket-limb interface during walking by the use of surface electromyography at different points on the upper and lower leg comparing walking characteristics of amputees with non-amputee subjects. The reading materials for this course include articles from PLoS ONE and the Journal of Neuroengineering and Rehabilitation.
