Katsuhira J, et al. - Researchers previously developed a trunk orthosis with joints providing resistive force (TORF) to modify malalignment of the trunk and pelvis and confirmed its positive effects in stroke patients during level walking without an ankle–foot orthosis (AFO). In this current investigation, they investigated whether this trunk orthosis and an AFO had synergistic impacts during level walking in community-dwelling patients with chronic stroke. They found an increase in the gait speed of stroke patients because of the modified trunk and pelvis alignment resulting from TORF-induced increased ankle joint plantar flexion moment at the end of the single stance phase during level walking in these subjects.
