剪切波弹性成像在辅助软组织松解术后跟腱功能评估中的应用

Effect of Instrument-assisted Soft Tissue Mobilization on Achilles Tendon Using ShearWave Elastography

目的利用高频超声剪切波弹性成像评估辅助软组织松解术(IASTM)对健康成人跟腱的作用。方法2020年7月至12月,健康成人受试者52例随机分入对照组(n=15)和试验组(n=37)。试验组接受左侧跟腱IASTM治疗,隔天1次,共2周;对照组不作处理。治疗前、首次治疗后即刻、治疗后3 d,采用高频超声和超声剪切波弹性成像测量受试者左侧跟腱厚度和弹性模量。结果末次治疗后,试验组5例脱失。治疗前,两组左跟腱厚度、弹性模量均无显著性差异(t<0.63,P>0.05)。治疗后即刻,试验组左跟腱厚度较对照组减少(t=2.149,P<0.05);治疗后3 d,左跟腱弹性模量平均值和最大值较对照组减少(t>2.134,P<0.05)。结论超声剪切波弹性成像可以量化评估IASTM对跟腱的疗效。

Objective To apply real-time shear wave elastography to observe the effect of instrument-assisted soft tissue mobilization(IASTM)on Achilles tendons for healthy adults.Methods From July to December,2020,52 healthy adults were assigned into control group(n=15)and experimental group(n=37)randomly.The experimental group received IASTM on left Achilles tendons,once another day for two weeks,while the control group received no treatment.The thickness and elastic modulus of the left Achilles tendons were measured with high-frequency ultrasound and shear wave ultrasound elastography on all the subjects,before treatment,immediately after the first treatment and three days after treatment,respectively.Results Five cases dropped down in the experimental group.There was no significant difference in thickness and elastic Young's modulus of the left Achilles tendons between two groups before treatment(t<0.630,P>0.05).The thickness of the left Achilles tendons was less in the experimental group than in the control group immediately after the first treatment(t=2.149,P<0.05),while average and maximum elastic Young's modulus was less three days after treatment(t>2.134,P<0.05).Conclusion Real-time shear wave elastography could quantify the thickness and elasticity of Achilles tendon,to evaluate the effect of IASTM.
