Point

●予測的姿勢制御（anticipatory postural adjustments：APAs）は，予測される姿勢動揺の相殺と効率的な重心の移動を目的に，姿勢動揺の予測の確度が高いほど効果的に調整される

●反応的姿勢制御は，姿勢動揺に関する種々の感覚入力をもとに，姿勢安定性の復元を目的に，ゴール志向に影響する予測，指示，注意，あるいは心理状態（不安など）に合わせて調整される

●APAsに対してはAPAsの低下を可能な限り抑制した条件下での反復練習が，反応的姿勢制御に対してはperturbation-based balance training（PBT）を実生活に類似した種々の課題設定で行うことが重要である
