Objective:To observe the effects of simplified wuqinxi on improving dynamic balance ability of the elderly. MethodsUsing the quasi-experiment research scheme, 60 volunteers were assigned into test group and control group, 30 in each group. Simplified wuqinxi was performed in the test group and stretching exercises were performed in the control group, with an exercise course of 4 months. The indicators of dynamic balance ability of the volunteers with eyes open and closed were observed on the Biodex balance tester.  Results:①57 patients completed the experiment, including 29 and 28 volunteers in the test group and the control group respectively. ②With eyes open, there were no significant differences in the overall balance index, anterior-posterior balance index and left-right balance index between week 16 and week 0 in both groups (P>0.05). There were no significant differences in the overall balance index, anterior-posterior balance index and left-right balance index between the groups at week 0, week 8 and week 16 (P>0.05). ③The ANOVA analysis of repeated measurements showed that with eyes open, there was statistical significance in the time factor of intra-group variations of the overall balance index and anterior-posterior balance index (P<0.05), while there was no statistical significance in the time * group factor of all indicators (P>0.05), suggesting that there was no interaction between time and group. There was no significant difference in the group factor of the inter-group variations of all indicators (P>0.05). ④With eyes closed, in the test group, the overall balance index, anterior-posterior balance index and left-right balance index decreased significantly at week 8 compared to week 0, at week 16 compared to week 0 (P<0.05); there were significant differences in the overall balance index, anterior-posterior balance index and left-right balance index between week 16 and week 8 (P<0.05). In the control group, the overall balance index and anterior-posterior balance index decreased significantly at week 16 compared to week 0, at week 16 compared to week 8 (P<0.05); and the left-right balance index decreased significantly at week 16 compared to week 0, at week 8 compared to week 0 (P<0.05). There was significant difference in the overall balance index between the groups at week 8 (P<0.05); there were significant differences in the overall balance index and left-right balance index between the groups at week 16 (P<0.05). ⑤The ANOVA analysis of repeated measurements showed that with eyes closed, there was statistical significance in the time factor of intra-group variations of the overall balance index, anterior-posterior balance index and left-right balance index (P<0.05), while there was no statistical significance in the time * group factor of all indicators (P>0.05), suggesting that there was no interaction between time and group. There was statistical significance in the group factor of the inter-group variations of the overall balance index and left-right balance index (P<0.05).  Conclusion:Simplified wuqinxi exercise can increase the control ability and stability of the elderly’s upright posture, improve their dynamic balance ability, and the mechanism of action may be increasing sensitivity of the vestibular system and sensory system in the elderly.
