Effect of transfemoral prosthetic socket interface design on gait, balance, mobility, and preference: A randomized clinical trial.

Background: There are alternative transfemoral (TF) socket interface designs that have not been compared with the standard of care, ischial ramus containment (IRC). The interface directly affects performance.

Objectives: To compare 3 TF interface designs, IRC, dynamic socket (DS), and subischial (Sub-I), regarding gait, balance, mobility, and preference.
