腋拐长度预测法研究

Study of estimating the length of crutches

的探讨预测腋拐长度的最佳方法。方法选择 99名健康学生为试验对象 ,其中男性 5 0名、女性 49名 ,用分散分析中的误差值预测腋拐长度及扶手高度。结果身高 -4 1cm的误差值为 7.0 71,肘尖至同侧第 3指距离的误差值为 9.165。结论在各种预测法中 ,身高 -4 1cm是最准确的适合预测腋拐长度的方法 ;肘尖至同侧第 3指距离是最准确的、适合预测扶手高度的方法。

ObjectiveTo study the best estimating method of measuring length of crutches.Methods99 healthy student acted as volunteers for the test and the height of crutches was estimated with error margin of linear regression.ResultsThe error value of subtracting 41cm from the height of the subject was 7.071, and the error value of tip of Olecranon to the 3rd fingertip was 9.165.Conclusion The value of subtracting 41cm from the height of subject is more reliable in estimating the ideal length of crutches. The value of tip of Olecranon to the 3rd fingertip is ideal for determining fitting of the handgrip.
