【摘要】 目的探讨青少年运动员超声骨龄测试过程中声速(SOS)值的变化特点,为进一步完善超声技术判读骨龄提供科学依据。方法用超声骨龄仪器对上海市1843名青少年运动员进行检测。结果男女运动员和普通青少年SOS值变化规律相同,随着时间年龄增长呈线性增长趋势,但以CHN分组的男女运动员和普通青少年比较,运动员SOS值基本都高于普通青少年。以SOS值为主要变量的超声骨龄二元回归方程,虽然精确度一般,但是复相关系数(R)较高(0.75～0.84,P值均<0.01)。结论有必要通过CHN方法建立青少年运动员CHN超声标准。采用SOS值和其他一些变量来建立青少年运动员CHN超声骨龄评价系统是可行的。更多还原

【Abstract】 Objective To explore the characteristic of SOS during measurement of bone age with ultrasonic device for teenager’s athletes and to give some scientific foundations for improvement further.Methods The bone age of 1 843 athletes was measured by bone age with ultrasonic device in Shanghai and compared the results with common teenagers.Results Male and female athletes resembled the common teenagers in the characteristic of varity of the SOS,the SOS increasing with age.However,when grouped by CHN method,the SOS of athletes was higher than common teenagers.Although the accuracy of the regression equation model by major factors of SOS established was low,the multiple correlation coefficient R was high(0.75~0.84,P<0.01).Conclusion It is necessary established ultrasonic bone age,for teenagers athletes basing on CHN method.In addition,establishing ultrasonic bone age system by SOS and other parameter basing on CHN method for teenagers athletes is feasible.更多还原
