摘要

目的:评价颈型颈椎病单侧颈痛患者颈椎活动时两侧胸锁乳突肌功能.方法:选取40例颈型颈椎病单侧颈痛患者,采用表面肌电图仪采集其颈椎前屈、后伸、右侧屈、左侧屈、右旋、左旋时两侧胸锁乳突肌的表面肌电信号,利用表面肌电图仪自带软件处理表面肌电信号,并生成表面肌电标准分析报告和表面肌电频率/疲劳度分析报告,提取报告中的平均肌电(averaged electro-myography,AEMG)值、积分肌电(integrated electromyography,IEMG)值、平均功率频率(mean power frequency,MPF)值及中值频率(median frequency,MF)值进行统计分析.结果:颈型颈椎病单侧颈痛患者颈椎前屈、后伸、右侧屈、左侧屈、右旋、左旋活动时,疼痛侧胸锁乳突肌的AEMG值和IEMG值均小于非疼痛侧[前屈:(12.915±7.302)μV,(18.750±14.520)μV,Z=-5.497,P=0.000;(582.315±295.895)μV·s,(883.635±549.678)μV·s,Z=-5.511,P=0.000;后伸:(15.510±18.862)μV,(19.215±17.137)μV,Z=-2.971,P=0.003;(684.635±777.440)μV·s,(898.240±923.353)μV·s,Z=-3.038,P=0.002;右侧屈:(16.710±14.353)μV,(22.955±14.697)μV,Z=-2.473,P=0.013;(703.115±601.570)μV·s,(994.365±599.673)μV·s,Z=-2.433,P=0.015;左侧屈:(12.255±5.255)μV,(17.005±13.523)μV,Z=-2.393,P=0.017;(527.070±266.853)μV·s,(731.240±519.03)μV·s,Z=-2.406,P=0.016;右旋:(17.195±27.397)μV,(39.715±50.327)μV,Z=-2.063,P=0.039;(739.535±1181.48)μV·s,(1813.390±2146.325)μV·s,Z=-2.057,P=0.040;左旋:(15.515±29.353)μV,(40.250±53.145)μV,Z=-2.016,P=0.044;(725.245±1262.037)μV·s,(1729.850±2385.365)μV·s,Z=-2.070,P=0.038],疼痛侧胸锁乳突肌的MPF值和MF值与非疼痛侧相比,差异均无统计学意义[前屈:(63.480±26.205)Hz,(62.115±34.965)Hz,Z=-1.237,P=0.216;(39.840±30.515)Hz,(38.110±39.990)Hz,Z=-0.363,P=0.717;后伸:(65.160±25.250)Hz,(67.820±26.727)Hz,Z=-0.148,P=0.882;(42.030±33.111)Hz,(45.930±20.975)Hz,Z=-1.593,P=0.111;右侧屈:(64.085±24.470)Hz,(65.525±25.500)Hz,Z=-0.417,P=0.677;(38.355±29.713)Hz,(42.375±23.113)Hz,Z=-0.484,P=0.628;左侧屈:(57.905±18.997)Hz,(58.530±19.820)Hz,Z=-0.390,P=0.697;(34.800±19.598)Hz,(36.255±19.687)Hz,Z=-0.444,P=0.657;右旋:(67.460±27.015)Hz,(69.410±18.528)Hz,Z=-0.255,P=0.798;(47.130±20.742)Hz,(48.920±27.063)Hz,Z=-0.914,P=0.361;左旋:(62.035±25.763)Hz,(66.200±22.447)Hz,Z=-0.349,P=0.727;(45.330±28.12)Hz,(47.025±21.93)Hz,Z=-0.444,P=0.657].结论:颈型颈椎病单侧颈痛患者在颈椎活动时,疼痛侧胸锁乳突肌较非疼痛侧肌肉收缩能力减弱,但两侧胸锁乳突肌肌肉疲劳度无差异.
