【摘要】：目的:應(yīng)用最大質(zhì)心壓力中心傾角法,精確評(píng)估青、中、老年人群的靜態(tài)平衡功能,比較不同年齡段人群靜態(tài)平衡能力差異及特征。方法:使用三維運(yùn)動(dòng)捕捉系統(tǒng)及測(cè)力臺(tái),采集15例青年(18～40歲)、10例中年(41～65歲)及12例老年(65歲)健康受試者,在睜眼雙足站立、閉眼雙足站立,睜眼單足站立及閉眼單足站立4種狀態(tài)下的質(zhì)心及壓力中心數(shù)據(jù),計(jì)算其在矢、冠狀面上的質(zhì)心壓力中心傾角,以各組平均峰值進(jìn)行統(tǒng)計(jì)分析。結(jié)果:在睜眼雙足站立及閉眼單、雙足站立3種狀態(tài)下,不同年齡段人群在矢、冠狀面的傾角差異均無統(tǒng)計(jì)學(xué)意義(p0.05);而在睜眼單足站立時(shí),青、中年組與老年組間,傾角在矢、冠狀面方向,差異都有統(tǒng)計(jì)學(xué)意義(p0.05)。結(jié)論:在單足站立情況下,老年組的質(zhì)心壓力中心傾角顯著大于青、中年組,提示人的穩(wěn)定性65歲以后退步較為顯著。應(yīng)用最大質(zhì)心壓力中心傾角能更精確的量化靜態(tài)平衡能力,評(píng)估不同年齡段人群的靜態(tài)平衡特征;單足站立下的最大質(zhì)心壓力中心傾角可以敏感地檢測(cè)出老年人群的平衡功能衰退,有望為臨床靜態(tài)平衡提供一種新的靜態(tài)平衡評(píng)估指標(biāo)。
[Abstract]:Aim: to evaluate the static balance function of the young, middle and aged population accurately by using the maximum centroid pressure center inclination method, and to compare the differences and characteristics of the static balance ability among different age groups. Methods: using a three-dimensional motion capture system and a force measuring table, 15 young people aged 1840 years old and 10 young adults aged 41 to 65 years old and 12 healthy subjects aged 65 years old were collected to stand with eyes open on both feet and with closed eyes on both feet. The centroid of mass and pressure center data of standing on one foot with open eyes and standing on one foot with eyes closed were calculated and the inclination of the center of mass pressure center on sagittal and coronal plane was calculated and the statistical analysis was carried out on the average peak value of each group. Results: there was no significant difference in the tilt angle of sagittal and coronal plane in different age groups under the condition of standing with eyes and eyes closed and standing on both feet, but when standing on one foot with open eyes, the inclination angle was sagittal in the young, middle age group and the old group, and the angle of inclination was in the sagittal angle between the young group and the middle age group. In the coronal plane, the differences were statistically significant (P 0.05). Conclusion: under the condition of standing on one foot the inclination of centroid pressure center in the elderly group is significantly higher than that in the young and middle age group which suggests that the stability of the elderly is more obvious after 65 years of age. The static equilibrium characteristics of different age groups can be evaluated by using the maximum centroid pressure center inclination angle to quantify the static balance ability more accurately. The maximum centroid pressure center inclination under standing on one foot can sensitively detect the decline of balance function in the elderly population, which is expected to provide a new static balance evaluation index for clinical static balance.
