Amputee locomotion: Lower extremity loading using running-specific prostheses

Abstract: Carbon fiber running-specific prostheses (RSPs) have allowed individuals with lower extremity amputation (ILEA) to actively participate in sporting activities including competitive sports. In spite of this positive trait, the RSPs have not been thoroughly evaluated regarding potential injury risks due to abnormal loading during running. Vertical impact peak (VIP) and average loading rate (VALR) of the vertical ground reaction force (vGRF) have been associated with running injuries in able-bodied runners but no… Show more

“…This is likely to prevent injury of the residual limb (Dudek et al, 2005;Milner et al, 2005). The high impact peaks and tendency towards higher loading rates of the IL agrees with past research on running (Hobara et al, 2014) and…”

“…The inability on the PL to increase vertical and propulsive forces will result both in reduced accelerations and shorter aerial times. This supports the mechanism that higher speeds will result from increased SF rather than SL, consistent with past research on amputee treadmill and over-ground running [5,6,10].…”

“…SL increases are the primary mechanism to run at faster sub-maximal steady-state speeds (between 3.5-7m/s) and the ankle plantarflexors play a primary role [8] with faster sprinting speeds achieved though increasing ground reaction forces [9] including their rate of development and decline. It is unclear how amputees alter SL, SF and ground reaction impulse to run at different sub-maximal speeds without a functioning ankle joint, as research is limited to imposed controlled speeds using different designs of RSP [6,10,11]. Potentially, a spontaneously self-selected running speed may be selected to optimise the mechanics of any prosthesis.…”

“…However, porous biomaterials used in load-bearing orthopaedic applications are often subjected to various types of daily activities such as walking, hopping, and running. These activities are associated with different types of loading profiles [25][26][27] that might be different in their magnitude, frequency bands, and other characteristics.…”
