Influence of Socket Volume on Prosthesis Performance

Influence of Socket Volume on Prosthesis Performance

The purpose of this study is to investigate how residual limb fluid volume, gait, prosthesis use, perceived comfort, and satisfaction with the prosthesis are affected by size of the prosthetic socket. Subjects are tested after wearing a nominal socket for 1 month and again after wearing a slightly oversized socket for 1 month.

Inclusion Criteria:

• transtibial amputee
• at least 18 months post amputation
• over 18 years of age
• capable of treadmill walking and 90 seconds of continuous standing
