Key Points

The study aimed to investigate the relationship between ankle dorsiflexor strength and the use of lower-limb orthoses at discharge in acute stroke patients.
Retrospective cohort design
Analyzed strength of ankle dorsiflexors on affected side
Compared strength with use of lower-limb orthoses at discharge
Assessed acute functional impairment levels
Approximately 40% of stroke patients used lower-limb orthoses at discharge
Stronger ankle dorsiflexor strength correlates with decreased reliance on orthoses
Factors associated with orthoses use include severity of functional impairment at discharge

Abstract

Objectives: Approximately 40% of stroke patients discharged from rehabilitation hospitals achieve restored gait using an ankle–foot orthosis. However, whether the use of lower-limb orthoses (LLO) at discharge is required is unknown in the acute phase. Therefore, it is difficult to explain the use of LLO to patients and their families. The aim of this study was to investigate the factors associated with the use of LLO at discharge based on acute functional impairment.
