ABSTRACT
Objective To explore the value of real-time shear wave elastography in evaluating gastrocnemius muscle elasticity in patients with lumbar disc herniation.Methods One hundred patients with clinically diagnosed unilateral lumbar disc herniation were selected.Selective nerve root block combined with ozone ablation and pulsed radiofrequency therapy via the lateral crypt was performed.The real-time shear wave elastography was applied to detect the mean elastic modulus (Mean) and the maximum elastic modulus (Max) of bilateral tense gastrocnemius muslcs (kPa) before and after treatment.Statistical analysis was done.Results The EMean and EMax values of ipsilateral tension in gastrocnemius muscle before treatment were (11.28±2.60)kPa and (15.26±2.63)kPa,lower than those of contralateral (EMean[16.284-5.25]kPa,EMax[21.13±6.62]kPa;t=78.241,64.634,both P<0.001).The EMean and EMax values of ipsilateral tension in gastrocnemius muscle after treatment were (13.18±2.38)kPa and (17.63± 2.73)kPa,higher than those before treatment (t=6.407,14.815,both P<0.001).In different strength condition,EMean and EMax of gastrocnemius muscle before and after treatment were statistically significant (all P<0.001).With the myodynamia increasing,EMean and EMax also increased before and after treatment.The differences between patients with any two different myodynamia were statistically different (all P<0.05).Conclusion The muscle tissue recovery can be evaluated quantitatively by detecting EMean and EMax of tense gastrocnemius in patients with lumbar disc herniation using real-time shear wave elastography before and after treatment.
