痉挛型脑瘫等速测试的信度研究

Confidencc of Constant-Speed Test for Spastic Cerebral Palsy

为进一步研究等速测试评估脑瘫运动障碍的可能性及为进一步研究提供科学依据．对30例痉挛型脑瘫患儿利用BIODEXⅡAP型多关节等速测试及康复系统重复测试膝关节的峰力短，应用差值t检验和相关系数的检验进行统计学处理。结果：2次测试峰力矩慢速伸展时差异不显著，相关系数为0875。提示可以利用等速测试，尤其是低速伸展运动时的峰力矩来作为其下肢功能障碍的评估指标，并依此来指导康复训练。

In order to further study the possibility of constant-speed test to evaluate cerebral motion disturbance,peak torque of the joints was repeatedly tested in 30 children with spastic cerebral palsy by using BIODEX ⅡAP type multi-joint constant-speed testing and rehabilitation system- Statistical analysis was performed by using t test and correlation coefficient test. The results indicated that the two tested peak torque had no significant difference during low speed stretching exercise with the correlation coefficient being 0. 875. It was suggested that constant-speed test,especially the peak torque in low speed stretching exercise, could be used to be the indicator for evaluating the lower limb functional disturbance and to direct the rehabilitation treatment.
