フォースプラットフォーム記録を用いた生体力学的解析のための歩行開始の姿勢構成

Overview

This study presents a method for investigating the postural organization of gait initiation through force platform recordings, focusing on anticipatory postural adjustments (APA). The approach aims to help understand how the central nervous system functions during gait initiation and offers precision in capturing biomechanical variables relevant to patients with motor issues.
