Brockport体能测试在中国视力障碍青少年中的应用研究

Feasibility and reliability of the Brockport physical fitness test among visually-impaired adolescents in China

目的探究Brockport体能测试在中国视力障碍青少年中的可行性和可靠性,以确定其在临床实践和研究中的适用性。方法共纳入上海市盲童学校41名10~17岁视力障碍青少年,由相同的测试人员使用相同的测试仪器对受试者进行两次Brockport体能测试,包括体质量指数(BMI)、握力、修正版卷腹、俯卧背伸、背抓、单腿伸展坐位体前屈和20 m折返跑,测试的时间间隔为1周。结果Brockport体能测试各项目完成率均为100%。身高、体重、BMI、握力、修正版卷腹、俯卧背伸、单腿伸展坐位体前屈(左/右腿伸直)和20 m折返跑的组内相关系数(ICC)在全体受试者中依次为1.00,1.00,1.00,0.94,0.75,0.78,0.90,0.87,0.89,全盲受试者中为1.00,1.00,1.00,0.97,0.80,0.92,0.89,0.87,0.87,低视力受试者中为1.00,1.00,1.00,0.90,0.71,0.40,0.89,0.85,0.85。背抓(左/右手在上)的简单卡帕(KC)系数在全体受试者中为0.79,0.78,全盲受试者中为0.72,0.64,低视力受试者中为0.87,1.00。结论Brockport体能测试在中国视障青少年中是可行且可靠的体能测试方法,在低视力青少年中不推荐使用俯卧背伸测试。

Objective To investigate the feasibility and reliability of the Brockport physical fitness test in visually-impaired adolescents in China to determine its applicability in clinical practice and research.Methods A total of 41 visually-impaired adolescents 10-17 years of age were included.Body mass index(BMI),dominant grip strength,modified curl up,trunk lift,shoulder stretch,back-saver sit-and-reach and PACER were tested twice with a 1-week interval by the same tester using the same instrument.Results Each item in the Brockport physical fitness test was completed.The intraclass correlation coefficients for height,weight,BMI,dominant grip strength,modified curl up,trunk lift,back-saver sit-and-reach(left/right leg straight),and PACER in all subjects were 1.00,1.00,1.00,0.94,0.75,0.78,0.90,0.87,0.89,respectively.In blind subjects,the corresponding values were 1.00,1.00,1.00,0.97,0.80,0.92,0.89,0.87,0.87,respectively.In low-vision subjects,the corresponding values were 1.00,1.00,1.00,0.90,0.71,0.40,0.89,0.85,0.85,respectively.The Cohen kappa values for shoulder stretch(left/right hand on top)were 0.79 and 0.78 in all subjects,0.72 and 0.64 in blind subjects,and 0.87 and 1.00 in low-vision subjects.Conclusion The Brockport physical fitness test is a feasible and reliable physical fitness test for visually-impaired adolescents in China,however,trunk lift is not recommended for adolescents with low vision.
