- W2347875401 abstract "Objective To provide basis for rehabilitation programs of the patients with protrusion of lumbar intervertebral disc. Methods Sixteen subjects with lumbar intervertebral disc protrusion(divided into L_4 and L_5/S_1 nerve root abnormality groups)were measured with Cybex 330 isokinetic dynamometer at three angular velocities(60 °/s, 180 °/s, 300 °/s). A t-test for dependent samples was done with data on the peak torque of knee flexion and extension muscles, flexor/extensor ratios between involved and uninvolved limb of the patients with lower back pain seperately. Results The torque values of involved flexors and extensors at the three speeds separately decreased 17. 1%, 18. 4%, 22. 5% and 17. 3%, 12. 9%, 11. 8%. There were significant differences between the involved and uninvolved extremities(P 0. 05 - 0. 001 ). The flexor/extensor torque ratios of involves limb at the three speeds were greater than those of uninvolved limb in L_4 po up were. On the contrary, the flexor/extensor torque ratios of involves limb were lower than those of uninvolved limb in L_5/S_1 group were. Conclusion it is necessary to train knee flexor and extensor of involved extremity as well as lumbar flexor and extensor in patients with lumbar intervertebral disc protrusion." @default.
