Practical assessment of motor preparation-execution coupling during active ankle dorsiflexion in post-stroke gait: A pilot study.

ABSTRACT:

Objective

Active ankle dorsiflexion (AAD) has been proposed as a surrogate measure for gait-related motor control. However, whether the neural coupling between motor preparation and execution during AAD predicts gait ability remains unclear. This study examined whether μ-γ coupling was evaluated as a practical neurophysiological marker of gait performance.

Methods

In this study, 12 healthy adults and 4 patients with chronic stroke performed an AAD task and an overground walking task. Ankle kinematics, surface electromyography, and electroencephalography were simultaneously recorded. Corticomuscular coherence (CMC) and phase-amplitude coupling (PAC) were analyzed as indices of motor preparation-execution coupling. Gait performance was assessed based on gait speed and a Gait A
