推拿对股四头肌等速测评与表面肌电影响分析研究

Analysis of the effect of massage on isokinetic measurement and surface electromyography of quadriceps femoris

目的探讨推拿对股四头肌等速测评与表面肌电的影响。方法 32位常人行等速及表面肌电图测评。64位髌骨疼痛综合征患者行推拿治疗,并于治疗前后行等速及表面肌电图测评。结果治疗前后患男峰力矩/体重有差异[(0.71±0.30)vs(1.19±0.35)]。治疗前后患女峰力矩/体重有差异[(0.73±0.26)vs(1.18±0.37)]。60°/s等速运动下积分肌电分析,患男治疗前后VM、VL差异有统计学意义[(48.5±4.7)vs(74.7±4.3)]Hz、[(71.9±4.5)vs(93.2±4.2)]Hz。患女治疗前后VM、VL差异有统计学意义[(48.7±4.3)vs(74.5±4.1)]Hz、[(72.3±3.4)vs(93.6±4.1)]Hz。60°/s角速度等速运动下中位频率分析,患男治疗前后VM、RF、VL差异有统计学意义[(34.2±2.3)vs(45.8±2.5)]Hz、[(43.5±3.1)vs(53.7±2.6)]Hz、[(43.4±3.7)vs(54.5±3.0)]Hz。患者治疗前后VM、RF、VL差异有统计学意义[(34.3±2.2)vs(45.9±2.3)]Hz、[(43.3±3.4)vs(53.8±2.9)]Hz、[(43.7±3.6)vs(54.5±3.7)]Hz。结论推拿可改善患者股四头肌等速测评结果与表面肌电状况。

Objective To investigate the effect of Massage on isokinetic Measurement and Surface Electromyograpny of quadriceps femoris, Methods The isokinetie and surface electromyography of 32 people were measured.Sixtyfour patients with pateltar pain syndrome were treated with massage,and were conducted by constant velocity and surface EMG evaluation before and after treatment, Results The difference of male peak torque/weight before and after treatment was statistically significant [ （0.71± 0,30）vs（1,19 ± 0.35） ] .There was a significant difference in the peak torque/body weight of female patients before and after treatment [ （0.73 ± 0.26）vs（1.18 ±0.37） ] iThe integral eleetromyoe!ectric analysis of 600/s isokinetie exercise was showed that differences of VM, VL of male patients before and after treatment were statistically significant [ （48.5 ± 4.7）vs（74.7 ±4.3） ], [ （71.9± 4.5）vs（93.2 ± 4.2） ]. There were differences in VM and VL of female patients before and after treatment [ （48.7±4.3）vs（74.5 ± 4.1） ], [ （72.3± 3.4）vs（93.6 ± 4.1） ] .Differences of VM, RF,and VL were statistically significant before and after the treatment of female patients with 604/s angular velocity [ （34,2 ± 2,3）vs（45,8 ±2.5） 3, [ （43.5 ± 3.1）vs（53.7 ± 2.6） ], [ （43.4 ± 3.7） vs（54.5±3.0） ] .There were differences he, fore and after treatment in VM ,RF, VL of female patients [ （34.3± 2.2） vs（45.9 ± 2.3） ], [ （43.3± 3.4）vs（53.8± 2.9） ], [ （43.7±3.6）vs（54.5 ±3.7） ]. Conclusion Massage can improve the isokinetic evaluation of four biceps femoris muscle and surface electromyography.
