Effects Of Isokinetic Flexion And Extension Training With Different Angular Velocities On The Core Muscle Of Male Patients With Low Back Pain

Objective:To explore the training effect of different angular velocity on the core muscles of chronic low back pain,and to search out the better angular velocity of isokinetic therapy for chronic low back pain.Methods:60 patients with chronic low back pain,randomly divided into three groups(A.B.C),each group 20 people.The group A was the control group;the group B selected angular velocity of 30 °/s isokinetic muscle strength training,4 weeks,three times a week.The group C change of selected 90 ° angular velocity/s,other conditions same with group B,each group respectively measured peak torque peak torque/body work,average power,total work,flexion/extension before and after training.Results:①Peak Torque after training:There was significant difference in the peak torque of flexor and extensor between the three groups after the concentric isokinetic training(P<0.05).The low-speed group(30 °/s)training effect is better than that of the higher-speed group(90°/s),the higher-speed group(90 °/s)training effect is better than the control group;②Power after training:Compared with group A,the flexor and extensor average power of the group B.C were significant difference(P<0.05),but there was no significant difference between groups B and C(P>0.05).Both of low-speed(30 °/s)and higher-speed(90°/s)concentric isokinetic training can enhance the power of the trunk extensor muscle strength,but no statistical difference between different speeds.③ There was statistical difference in vas score between the three groups either before or after training(P>0.05),and statistical difference in B,C groups before and after training(P>0.05).Conclusion:1.Isokinetic muscle strength training can improve the core muscle strength,stability,coordination and other muscle indicators of the trunk of patients with chronic low back pain,with significant efficiency.2.In the same training intensity(group,timer,interval time to rest,etc.),under different angular velocity of isokinetic muscle strength training to improve the core truck muscles of patients with chronic low back pain there are differences in the effect of each index 3 isokinetic muscle strength training to reduce the pain of patients with low back pain effectively,reduce vas scores before and after the training,subjects had feelings of pain relief,has certain clinical value.4.Isokineric can be used as a treatment technique to improve and improve the core muscle group of patients with chronic low back pain in clinical practice.According to the specificity of the influence of different speeds on different muscle indicators and according to the needs of improving the core muscle group,different angular velocities and movement modes can be selected for the training of different trunk core problems.
