摘要：
A controlled-stretch prosthetic liner comprising a polymeric material covered with at least a stretch-controlling fabric. Certain liner types, such as below knee (BK) liners, may also include a panel of more stretchable fabric so as to prevent any interference with knee flexion. The polymeric material of the liner may also be used to control liner stretch, such as by adding Kevlar pulp or other materials that increase the strength and reduce the elasticity of the polymeric material and/or by reducing the amount of plasticizer(s) present therein. The stretch-controlling fabric, possibly in conjunction with the polymeric material, acts to limit the longitudinal stretch of the liner while not adversely affecting the radial stretch thereof.
