Impact testing of the residual limb: System response to changes in prosthetic stiffness

Erin Boutwell, PhD, et al.

Shock absorption naturally occurs in nondisabled walking. It is important to restore this function in Veterans who walk with prosthetic limbs since impact forces can potentially cause long-term damage to the skin, soft tissues, and residual joints of both the intact and amputated limbs. We used a shock-absorbing pylon to vary prosthetic stiffness in transtibial prosthesis users and assessed shock absorption using a sudden loading evaluation device. Surprisingly, force transmission and prosthetic-side total limb stiffness were unaffected by changes in prosthetic limb stiffness. This result may be explained by the relatively low stiffness of the residual limb soft tissue.
