Changes of thickness and elasticity of skeletal muscles in diabetic patients and relative impact factors
Objective To observe changes of thickness and elasticity of skeletal muscles in patients with type 2 diabetes mellitus(T2DM)and relative impact factors.Methods Totally 62 T2DM patients(T2DM group)and 60 healthy adults(HC group)were prospectively recruited.Shear wave elastography(SWE)technology was used to measure the maximum Young's modulus(Emax)of the rectus abdominis and gastrocnemius muscles under relaxed and contracted states in both groups.The thickness and elasticity modulus of the skeletal muscles under the two states were compared between groups.Multiple linear regression analysis was performed to screen impact factors of the elasticity modulus of the rectus abdominis and gastrocnemius muscles.Results No significant difference of muscle thicknesses of rectus abdominis,nor of gastrocnemius muscle was found between groups under relaxed and contracted states(all P＞0.05).Under both relaxed and contracted states,the Emax of the rectus abdominis and gastrocnemius muscle in T2DM group were all lower than those in HC group(all P＜0.05).Multiple linear regression analysis showed that in T2DM group,the elasticity modulus of the rectus abdominis and gastrocnemius muscle under both relaxed and contracted states decreased linearly with disease duration,fasting blood glucose(FBG)and glycosylated hemoglobin(HbA1c)(all P＜0.05).Conclusion The elasticity modulus of skeletal muscle decreased in T2DM patients,and the reducing scales linearly related to disease duration,FBG and HbA1c.
