Effect of Alignment Change on the Gait Parameters of a Below-Knee Amputee

LOUIS EKUS, CPO AND SUSAN K. STIMMEL, MS*


A patient with a traumatic below-knee amputation and excellent gait in a conventional below-knee prosthesis was studied. One alignment parameter was chosen to facilitate statistical analysis. Anteroposterior placement of the socket was altered in increments of 1/4 inch and resulting changes in the gait were quantified. An in-depth analysis of gait parameters and the implications of the unpredictable results are discussed, emphasizing the importance of developing a quantitative gait analysis and alignment system based on objective criteria rather than the subjective system now used.
