The present study is an investigation of whether an intervention involving awareness of joint movement without vision (i.e., self-monitoring) contributes to improved stability of upright posture as measured immediately after self-monitoring.
Eighteen young adults (ages: 22.6 ± 2.2 years) participated in two interventions: self-monitoring and control. In the self-monitoring intervention, the blindfolded participants tried to reproduce a target angle using both the ankle and the wrist while self-monitoring the movement. In the control intervention, they performed the same task while continuously performing an arithmetic subtraction task.
Pre-post measurements of postural stability using a force plate for each intervention showed that self-monitoring significantly improved the stability of unipedal posture but not that of bipedal posture. Such beneficial effect for unipedal posture was obtained even when the participant monitored the wrist movement.
Self-monitoring was effective to improve postural stability in cases in which maintaining the whole body balance was challenging.
本研究旨在调查一种涉及无视觉情况下关节运动意识（即自我监测）的干预措施是否有助于在自我监测后立即测量时提高直立姿势的稳定性。
18名年轻成年人（年龄：22.6±2.2岁）参与了两项干预措施：自我监测和对照。在自我监测干预中，蒙眼参与者在自我监测运动时尝试使用脚踝和手腕重现目标角度。在对照干预中，他们在持续执行算术减法任务的同时执行相同的任务。
使用测力板对每种干预措施进行姿势稳定性的前后测量表明，自我监测显著提高了单足姿势的稳定性，但未提高双足姿势的稳定性。即使参与者监测手腕运动，也能获得对单足姿势的这种有益效果。
在维持全身平衡具有挑战性的情况下，自我监测对于提高姿势稳定性是有效的。
