This study is focused on presenting data that supports the benefits of running-specific prosthesis (RSP) devices, with the goal of meriting medical necessity to fight denial claims. This research proposal compiles data and supportive evidence that RSP provides associated functional and physical benefits. Sepp et. al compared RSP and daily-use prosthetic (DUP) devices of 26 subjects using an instrumented treadmill at 5 randomized, steady-state speeds (3.0 m/s, 3.5 m/s, 4.0 m/s, and 5.0 m/s) while ground reaction forces were being collected and markers were placed to collect kinematic data. Further supportive data was presented by Highsmith et al in a double-blind study where 14 TTA used three different lower extremity feet (two DUP and one RSP) and completed an 18-phase obstacle course while time and performance were assessed. Together the comprised data in this study can be used to validate the benefits of RSP devices versus DUP and further broadcast and place pressure on the issue of denial claims regarding RSP devices for TTA.
