MRI and Ultrasound Elastography in the Evaluation of Changes in Catf Muscles before and after Rehabilitation of Lower Limbs in Children with Spastic Cerebral Palsy

Objective To investigate the effect of MRI and ultrasound elastography in the assessment of calf muscle changes before and after lower limb rehabilitation training in children with spastic cerebral palsy.Methods From March 2018 to March 2019,82 children with spastic cerebral palsy were enrolled in our hospital.All children were given professional reha bilitation training.MRI and ultrasound elastogra phy was performed before and after training.The maximum muscle movement before training was compared.Velocity,Young's modulus,Gross Motor Function Measure(GMFM)score,and MRI analysis,ultrasound elastography,and GMFM correlation.Results Before rehabilitation,the maximum contraction velocity of the gastrocnemius(8.21±1.13 mm/s)and soleus muscle(6.54±1.02 mm/s)was significantly lower than that after rehabilitation(10.18±0.97 mm/s,7.6210.91mm/s).Ultrasound elastogra phy showed that before the reha bilitation training,the natural rectal muscle of the child was longitudinally cut(48.13112.24),and the natural position was transected(46.15110.27).The Young's modulus value and the natural position of the soleus muscle were longitudinally cut(50.28113.12).The transverse modulus(48.23110.56)was higher in Young's modulus.Three months after rehabilitation training,the natural gastrocnemius was longitudinally cut(20.6315.36),and the natural position was transversely cut(19.15±5.27)Young's modulus.The values were significantly different from those of the soleus muscle(22.74±5.26),and the natu ral transverse(20.32±5.35)Young's modulus values we re significantly lower(P<0.05).Before rehabilitation,the GMFM score was(39.27±13.41),and the GMFM sco re was 59.38112.76 after 3 months of rehabilitation training.The difference was significant(P<0.05).MRI and ultrasound elastography scores were directly proportional to GMFM scores.Conclusion Both ultrasound elastography and MRI can evaluate the changes of calf muscles before and after rehabilitation in children with spastic cerebral palsy.However,the cost of ultrasound elastography is low,and it is easy to use and has little damage to children.It is worthy of clinical application.
