【摘要】：目的:完善健康青年静态立位平衡参数常模和探讨人处于不利站立条件下姿势控制变化规律。方法:从某军校本科学员中随机抽取108名,对8种不同站立条件下的立位平衡功能进行测试,同时比较不同站立姿势下重心晃动的变化。结果:与睁眼站立相比,闭眼站立和闭眼站立于脚垫上,人体重心会不自主地向脚掌移动,同时重心晃动的轨迹长度和面积明显增加,而单位面积轨迹长度明显降低。另外,人体前后方向晃动的程度较大,而左右晃动的程度稍小。结论:健康人姿势控制由视觉、前庭和下肢本体感觉等共同维持的,任何系统受到限制,都会影响平衡功能。当人处于不利站立条件时,人的身体会本能地向前倾斜来维持平衡,同时本研究为涉及人体立位平衡方面的研究提供了新的研究方法和思路。
[Abstract]:Objective: to improve the norm of static standing balance parameter of healthy young people and to explore the changing rule of posture control under unfavorable standing condition. Methods: 108 cadets were randomly selected from a military academy. The balance function of standing position in 8 different standing conditions was tested, and the changes of center of gravity in different standing positions were compared. Results: compared with standing with open eyes, closed eyes stood and closed eyes stood on foot pads. The center of gravity of the human body moves involuntarily towards the soles of the foot, and the trajectory length and area of the center of gravity sloshing increase obviously, while the trajectory length of the unit area decreases obviously. In addition, the degree of sloshing in the front and rear directions of the human body is greater. Conclusion: posture control in healthy people is maintained by vision, vestibule and lower extremity proprioception, and any system is restricted, which will affect the balance function. Human body instinctively tilts forward to maintain balance, and this study provides new research methods and ideas for the study of human orthostatic balance.
