Abstract
In vivo rate-controlled (2, 5 and 8 mm/s) indentation tests were conducted on the soft tissues of the residual limb of four individuals with trans-tibial amputation. Force relaxation trials were also conducted. The cyclic in vivo indentation tests indicated that the bulk soft tissue response to compressive load is nonlinear and, for the indentation rates tested, nearly independent of the loading rate. Significant inter- and intra-subject stiffness variations were observed. The force relaxation studies indicated that approximately 80% relaxation may occur; the relaxation time constants (Kelvin model) ranged from 150 to 300 seconds. Additional subject trials are currently being conducted.
