Effect of prosthetic gel liner thickness on gait biomechanics and pressure distribution within the transtibial socket

Erin Boutwell, MS, et al.


Figure 1. Pressure sensor placement on residual limb. Sensors are labeled sPT (patellar tendon), sDT (distal anterior tibia), sDE (distal end of the tibia), sFH (fibular head), and sMG (medial gastrocnemius). Only data from sPT, sDT, and sFH were analyzed for all subjects.

This study evaluates how prosthetic gel liners worn between the residual limb and the prosthetic socket can affect persons with below-knee amputations. Each subject wore both a thin and a thick gel liner and walked at a comfortable speed. Forces and pressures were recorded during walking, and the two liners were compared. The force under the foot dur- ing loading was slightly increased with the thicker liner, but lower pressure was found at one high-pressure area on the residual limb with the thicker liner. Many subjects found the thicker liner more comfortable to wear, especially people with bony residual limbs.
