To discuss the effect of sling exercise training using advanced and closed kinetic chain method on balance ability of patients with knee osteoarthritis (KOA ) .A total of 40 patients with knee osteoarthritis were assigned randomly to control group (n= 10 ) and experimental group (n = 30 ) ,received both conventional physical therapy and medication .Experimental group patients received further sling exercise therapy such as quadriceps and hamstring muscle strength training ,joint activity training and proprioceptive training .In this paper ,the balance a‐bility of knee healthy side and affected side were contrastively investigated between control group and experimental group patients after four weeks of treatment .The results shows that control group there was a small statistically significant effect (P<0 .05) about several stabili‐ty index at knee healthy side under antero‐posterior axis and A2‐A6 axis positions .There was statistically significant difference about the experimental groups balance stability index ( P<0 .05) .Control group there was a small statistically significant effect (P< 0 .05) about stabili‐ty index at affected side under antero‐posterior axis position .In contrast to ,experimental group there was a small statistically significant effect (P< 0 .05) about several stability index at af‐fected side .After the sling exercise therapy using advanced closed kinetic chain ,the stability in‐dexes of dynamic balancing capabilities of the patients with knee osteoarthritis problems have been greatly improved and made patients increased control ability on joint position and kinaes‐thesis abilities .%目的：探讨悬吊下进阶式闭链运动训练法对膝关节骨性关节炎（KOA ）患者平衡能力的影响。方法：选取40例膝关节骨性关节炎患者，随机分为对照组（n＝10）和实验组（n＝30）；40例患者均接受常规物理治疗和药物治疗，实验组患者增加悬吊运动训练，如股四头肌和腘绳肌肌力训练、关节活动度训练、本体感觉训练等。治疗4周后，对两组患者膝关节健、患侧平衡能力进行了对比研究。结果：对照组健侧稳定指数中前、后轴、A2‐A6轴的稳定指数有统计学差异（P＜0．05）；实验组健侧各项稳定指数均具有统计学差异（P＜0．05）。对照组患侧稳定指数中前、后轴的稳定指数具有统计学差异（ P＜0．05）；实验组患侧的各项稳定指数显示均具有统计学意义（P＜0．05）。结论：悬吊下进阶式闭链运动疗法能够明显改善膝关节骨性关节炎患者的平衡能力，可以提高患者对关节位置的控制及运动感觉能力。
