Establish normative values for knee valgus angle during drop jump and step landings.
Observational.
University biomechanics laboratory.
100 physically active asymptomatic individuals (50 male, 50 female) aged 18-28 years old.
Knee valgus angle during drop jump and step landings.
There were no differences between genders during the step landing task (p < 0.12) but there were differences during the drop jump landing task (p < 0.048). Both males and females showed no significant differences between sides for either of the tasks (p > 0.05) or between the valgus angle generated for either of the tasks (p > 0.05).
It would appear in order to be regarded as an average "normal" performance during a drop jump landing task knee valgus angle should be symmetrical and in the range of 7-13 degrees for females and 3-8 degrees for males. For a unilateral step landing task knee valgus angle should be symmetrical and in the range of 5-12 degrees for females and 1-9 degrees for males.
建立在跳下和单腿落地时膝关节外翻角度的正常值。
观察性研究。
大学生物力学实验室。
100 名身体活跃、无明显症状的个体（50 名男性，50 名女性），年龄在 18-28 岁之间。
在跳下和单腿落地时膝关节外翻角度。
在单腿落地任务中，性别之间没有差异（p＜0.12），但在跳下落地任务中存在差异（p＜0.048）。男性和女性在两种任务中的任何一侧都没有显著差异（p＞0.05），也没有两种任务产生的外翻角度存在显著差异（p＞0.05）。
在跳下落地任务中，为了被视为平均“正常”表现，膝关节外翻角度应该是对称的，女性范围为 7-13 度，男性范围为 3-8 度。对于单侧单腿落地任务，膝关节外翻角度应该是对称的，女性范围为 5-12 度，男性范围为 1-9 度。
