[Purpose] To study the correlation among proprioception, muscle strength, and balance. [Subjects and Methods] A balance testing system (Biodex Balance System, BBS) and an isokinetic testing system (Biodex System 4, BS4) were used to test related indexes in 24 healthy young females. [Results] With the knee joint at 15 degree flexion, proprioception was significantly correlated with Limits of Stability-Time values, and was highly significantly correlated with Limits of Stability-Overall and Athlete Single Leg Medial/Lateral values. The sense of force was significantly correlated with Limits of Stability-Overall and Athlete Single Leg-Overall values. Quadriceps strength was significantly associated with Limits of Stability-Overall, Athlete Single Leg Medial/Lateral, and Athlete Double Leg-Overall values. The ratio of Quadriceps to Hamstring strength was significantly correlated with Athlete Single Leg Medial/Lateral, and Athlete Single Leg-Overall values. With the knee joint at 45°, proprioception was highly significantly correlated with dynamic balance, and was significantly correlated with double foot support under static balance; force sense had a high correlation with Limits of Stability-Overall, but no correlation with other indexes. Quadriceps strength had a significant correlation with dynamic and static balance; the ratio of Quadriceps/Hamstring had a highly significant correlation with Limits of Stability-Overall, Athlete Single Leg-Anterior/Posterior and Athlete Single Leg-Overall. [Conclusion] At different knee angles, the correlation differs among proprioception, force sense, quadriceps strength, the Quadriceps/Hamstring ratio, and balance.
[目的] 研究本体感觉、肌肉力量和平衡之间的相关性。[对象与方法] 采用平衡测试系统（Biodex平衡系统，BBS）和等速测试系统（Biodex系统4，BS4）对24名健康年轻女性的相关指标进行测试。[结果] 膝关节屈曲15°时，本体感觉与稳定性极限-时间值显著相关，与稳定性极限-总体值和运动员单腿内侧/外侧值高度显著相关。力觉与稳定性极限-总体值和运动员单腿-总体值显著相关。股四头肌力量与稳定性极限-总体值、运动员单腿内侧/外侧值和运动员双腿-总体值显著相关。股四头肌与腘绳肌力量比值与运动员单腿内侧/外侧值和运动员单腿-总体值显著相关。膝关节屈曲45°时，本体感觉与动态平衡高度显著相关，与静态平衡下的双脚支撑显著相关；力觉与稳定性极限-总体值高度相关，但与其他指标无关。股四头肌力量与动态和静态平衡显著相关；股四头肌/腘绳肌比值与稳定性极限-总体值、运动员单腿前后向和运动员单腿-总体值高度显著相关。[结论] 在不同膝关节角度下，本体感觉、力觉、股四头肌力量、股四头肌/腘绳肌比值与平衡之间的相关性存在差异。
