| Objective: To observe the efficacy of Non-operative Spinal Decompression System (SDS) on the lumbar pain, lumbar motion function and paravertebral muscle function, the degree of lumbar disc herniation and disc height (DH) in the treatment of lumbar disc herniation. Methods: Forty cases of LDH were randomly divided into the traction group and SDS group (n=20 in each group). The traction group was given ordinary traction treatment on the basis of conventional rehabilitation, and SDS group was given SDS treatment on the basis of conventional rehabilitation. Before and after the treatment, the Visual Analog Scale (VAS) score was used to evaluate the degree of low back pain, Japanese Orthopaedic Society (JOA) Lower Lumbar pain scale was used to evaluate the lumbar motor function, surface electromyography was used to evaluate paraspinal muscle function, and MRI was used to evaluate the disk herniation index (DHI) and DH. Results: After 6 weeks of treatment, VAS score in both groups was significantly lower than that pre-treatment (all P<0.05), and JOA score was significantly higher than that pre treatment (all P<0.05). VAS score in SDS group was significantly lower than that in traction group (P<0.05), and JOA score was significantly higher than that in traction group (P<0.05). AEMG and MPFs of erector spinae and multifidus in both groups were significantly higher than those pre treatment (all P<0.05), and AEMG and MPFs in SDS group were significantly higher than those in traction group (P<0.05). DHI of the lesion segment in both groups was significantly lower than that pre treatment (all P<0.05), and DH was significantly higher than that pre-treatment (P<0.05). DHI in SDS group was significantly lower than that in traction group (P<0.05), but there was no significant difference in DH between two groups. Conclusion: SDS could effectively relieve pain, improve the function of lumbar and paravertebral muscle, and the degree of lumbar disc herniation of the LDH patients, and the effect is obviously better than that of the general traction. |
