Abstract

Background: Little is known about the existence and impact of interactions among multiple impairments to gait independence. The purpose of this study is to reveal the interaction of physical functions and its impact on gait independence in stroke patients. Methods: This retrospective study included 108 subacute stroke patients. We conducted a decision tree analysis to examine the existence of interactions in relation to gait independence among the gross motor function of lower limb, knee extension strength, sensory function, and trunk function. Further, we confirmed the existence and impact of interaction detected via the decision tree after adjusting for the effects of confounding factors using logistic regression. Results: The knee extension strength and proprioception on the affected side were selected in the first and second level of the decision tree. In addition, the knee extension strength was selected in the third level. The interaction of the knee extension strength and proprioception on the affected side was significantly associated with gait independence, both before and after adjusting for age, visuospatial perception, and cognitive functions. Conclusions: Our results suggest that the interaction of the knee extension strength and proprioception on the affected side is strongly associated with gait independence in stroke patients.
