The residual limb-socket interface pressures were measured in 13 transtibial amputees who use prostheses with side joints and thigh lacers. The hypothesis of this study was that the interface pressures with a thigh lacer are lower than the pressures without a thigh lacer. Comparison of the interface pressures with and without thigh lacer-side joints revealed a significant difference (p < 0.05). The reduction in the interface pressures indicates that a thigh lacer redistributes the pressures from the residual limb onto the thigh, and a thigh lacer-side joint suspension may be indicated in some transtibial amputees.
