感觉统合力量训练对老年人双任务动态平衡能力的影响

Effect of Sensory Integration Strength Training on the Dynamic Balance Ability of the Elderly

目的:研究感觉统合力量训练对老年人双任务动态平衡能力的影响。方法:39名老年人被随机分到控制组(C组)、普通力量训练组(ST组)和感觉统合力量训练组(SIST组)。C组进行日常活动,ST和SIST组受试者分别进行16周的ST和SIST训练,每周3次,每次45min。3组同时在试验前、第8周、第16周进行双任务动态平衡能力测试和等速力量测试。测试指标包括DT(dual-task)10m行走时间、DT-TUGT(dualtask-time up and go test),膝关节(60°/s)屈、伸肌峰力矩(PT)、屈/伸肌力比(H/Q)。结果:在训练第8周和第16周时,同C组相比,ST、SIST组膝关节(60°/s)屈、伸PT都出现显著性差异(P<0.01)。但两组间PT值均无显著性差异(P>0.05)。H/Q随着训练时间逐渐集中,至第16周时2组都已经相对集中,且与ST组相比,SIST组的H/Q更加集中。在训练第8周时,ST和SIST组DT-10m行走时间和DT-TUGT测试结果明显减少,且2组趋势相似。同C组相比,都具有显著性差异(P<0.01)。但2组之间相比,没有显著性差异(P>0.05)。而训练到第16周时,同C组相比,都具有显著性差异(P<0.01)。 2组之间相比,出现了显著性差异(P<0.01)。结论:ST和SIST都能提高老年人双任务动态平衡能力,而SIST干预效果优于ST。其原因是对训练对老年人认知功能也起到了促进作用。与传统的身体单任务练习相比,被试更有兴趣参与SIST练习。

Objective:To examine the effect of sensory integration strength training on the dynamic balance ability of the elderly.Methods:Thirty-nine elderly were randomly assigned to the control group(group C), the general strength training group(ST group), and the sensory integration strength training group(SIST group).Group C conducted daily activities,and the Groups ST and SIST performed ST and SIST training respectively in 16 weeks,three times a week for 45 min.The three groups simultaneously performed a dual-task dynamic balance test and a isokinetic muscle testing at the beginning of the training,the 8th week and the 16th week.Test indicators include DT(dual-task)10 m walking time,DT-TUGT(dual task-time up and go test), knee join(t 60 °/s)flexion,extensor peak torque(PT), flexor and extensor strength ratio(H/Q).Results:At the 8th and 16th week of training, there was a significant difference in PT between the Groups ST and SIST(60°/s) compared with the Group C(P <0.01).However,there was no significant difference in PT values between the two groups(P>0.05).H/Q grad ually concentrated with the training time.By the 16th week,the two groups were relatively concentrated, and the H/Q of the Group SIST was more concentrated than the Group ST.At the 8th week of training,the DT-10 meter walking time and DT-TUGT test results in the Group ST and SIST were significantly reduced, and the trends in the two groups were similar.Compared with the Group C,there was a significant difference(P<0.01).However,there was no significant differ ence between the two groups(P >0.05).At the 16th week,there was a significant difference compared with the Group C(P <0.01).Significant differences(P<0.01) occurred between the two groups.Conclusions:Both ST and SIST can improve the dual-task dynamic balance ability of the elderly,and the SIST intervention effect is better than ST.The reason is that the training also promotes the cognitive function of the elderly.Participants were more interested in participating in SIST than traditional body single-task exercises.
