【摘要】：目的：運用表面肌電圖定量分析經肌電生物反饋儀治療后患側股直肌、股內側肌、股外側肌的肌力,探討肌電生物反饋儀對膝關節(jié)肌力恢復的療效。方法：膝關節(jié)僵硬患者28例,男性19例,女性9例；平均年齡35.53±9.20(18～55歲),身高173.89±8.72(159～183cm),體重71.64±10.07(52～83kg),病程12.82±8.03(3～24周)。隨機分成治療組和對照組,每組14例,治療組和對照組兩組患者的年齡、身高、體重及病程運用統(tǒng)計軟件進行比較,均無統(tǒng)計學差異(P0.05),所以兩組患者在治療前一般情況處于同一基線,具有可比性。兩組患者均給予常規(guī)康復治療,包括蠟療、運動療法、冷療；對照組采用常規(guī)康復治療；治療組采用常規(guī)康復治療輔以肌電生物反饋(廣州晶冠科技,型號565)治療。分別于治療前及治療后4周利用表面肌電圖(海神型號NDI-092)采集股外肌(VL)股直肌(RF)和股內肌(VM)的相對均方根振幅(RMS)進行比較,判斷治療前后患者這三組肌肉肌力的變化,所有數據均進行統(tǒng)計學處理。結果：1、對照組：治療前股直肌(RF)、股內肌(VM)和股外肌(VL)的相對增長的均方根振幅(RMS)均數為9.641±10.744,13.380±14.308,13.353±14.374,治療后股直肌(RF)和股內肌(VM)股外肌(VL)的相對增長的均方根振幅(RMS)均數為17.304±7.275,16.738±8.719,37.273±30.945,兩組數據行t檢驗,VL組數據均有統(tǒng)計學意義(P0.05)；其余兩組無統(tǒng)計學意義(P0.05).治療組：治療前股直肌(RF)、股內肌(VM)和股外肌(VL)的均方根振幅(RMS)均數為13.642±3.193,12.183±9.178,13.486±9.017,治療后股直肌(RF)、股內肌(VM)和股外肌(VL)的均方根振幅(RMS)均數為32.905±22.213,34.373±25.682,74.499±61.112,三組數據行t檢驗,均有統(tǒng)計學意義(P0.05)；治療組評價指標的改善程度明顯優(yōu)于對照組結論：常規(guī)康復治療可以改善患膝的肌力,但配合肌電生物反饋療法療效更顯著。
[Abstract]:Objective: to study the effect of surface electromyography (EMG) biofeedback instrument on the recovery of muscle strength of knee joint by quantitative analysis of muscle strength of the affected side of rectus femoris, medial femoral muscle and lateral femoral muscle after treatment with electromyoelectric biofeedback instrument (EMG). Methods: there were 28 cases of knee joint stiffness, male 19 and female 9, mean age 35.53 鹵9.20 (1855 years), height 173.89 鹵8.72 (159~183cm), body weight 71.64 鹵10.07 (52~83kg), course of disease 12.82 鹵8.03 (3weeks). They were randomly divided into treatment group and control group with 14 cases in each group. The age, height, weight and course of disease of the patients in the treatment group and the control group were compared by statistical software. There is no statistical difference (P0.05), so the two groups of patients in the general situation before treatment at the same baseline, comparable. Two groups of patients were given routine rehabilitation therapy, including wax therapy, exercise therapy, cold therapy; the control group was treated with routine rehabilitation; the treatment group was treated with routine rehabilitation combined with myoelectric biofeedback (Guangzhou Jingguan Technology, Model 565). Surface electromyography (NDI-092) was used to collect the relative root-mean-square amplitude (RMS) of the lateral femoral muscle (VL) and the intrafemoral muscle (VM) before and 4 weeks after treatment. All the data were processed statistically. Results: the mean RMS of relative increase of RMS of rectus femoris (RF), medial femoral muscle (VM) and external femoral muscle (VL) before treatment was 9.641 鹵10.744 鹵13.380 鹵14.308 鹵13.353 鹵14.374. The mean value of relative increase of root mean square amplitude (RMS) of rectus femoris (RF) and medial femoral muscle (VM) was 13.353 鹵14.374 before treatment. The data were 17.304 鹵7.275 and 16.738 鹵8.719 鹵37.273 鹵30.945 respectively. The data of VL group were statistically significant (P0.05). The other two groups had no statistical significance (P0.05). The mean root mean amplitude (RMS) of rectus femoris (RF), medial femoral muscle (VM) and lateral femoral muscle (VL) was 13.642 鹵3.19312.183 鹵9.1781.486 鹵9.017 before treatment. After treatment, the mean RMS of rectus femoris (RF), medial femoral muscle (VM) and extrafemoral muscle (VL) were 32.905 鹵22.2133t 34.373 鹵25.682n 74.499 鹵61.112, respectively (P0.05). Conclusion: routine rehabilitation therapy can improve the muscle strength of the affected knee, but the effect of EMG biofeedback therapy is more obvious than that of the control group.
