Effective assistance timing using characteristics of paretic ground reaction force in ankle robotic gait training for individuals with hemiparesis after stroke: a cross-sectional study.

ABSTRACT:

Background

Effective ankle plantarflexion assistance (PF assistance) requires precise timing and personalized adjustment using an ankle joint robot that assists both dorsiflexion and plantarflexion during walking. Previous studies suggest that peak paretic propulsion timing (Peak PP timing) is earlier in some individuals, indicating differences in ground reaction force (GRF) characteristics among individuals with stroke. Therefore, this study aimed to identify the effective timing of PF assistance according to anteroposterior GRF characteristics.

Methods

The study included twenty-three post-stroke individuals with hemiparesis. The participants walked on a treadmill under an unassisted condition, and at 30-50% and 40-60% gait cycle (GC) PF assisted conditions. The participant
