DOI: 10.1016/j.clinbiomech.2017.07.014
Abstract: BACKGROUND Patients with transtibial amputation adopt trunk movement compensations that alter effort and increase the risk of developing low back pain. However, the effort required to achieve high-demand tasks, such as step ascent and descent,… read more here.
