The effects of Pilates on pain, functionality, quality of life, flexibility and endurance in lumbar disc herniation

Effectiveness of transforaminal approach spinal endoscopy in the treatment of patients with lumbar disc herniation and the factors affecting its efficacy

OBJECTIVE

To compare the surgical metrics, improvement of functional scores, and clinical efficacy of percutaneous endoscopic transforaminal discectomy (PETD) and percutaneous endoscopic interlaminar discectomy (PEID) and to analyze the independent risk factors affecting the therapeutic efficacy of PETD.

METHODS

The clinical data of LDH (lumbar disc herniation) patients who underwent treatment in Shaanxi Provincial Nuclear Industry 215 Hospital from May 2020 to May 2022 were retrospectively collected, including 70 PEID cases and 74 PETD cases. The two groups were compared in terms of surgical indexes, such as operation time and bleeding volume, as well as changes in functional scores, such as preoperative and postoperative Visual Analogue Scale (VAS) scores and Oswestry Disability Index (ODI). The clinical efficacy was evaluated according to the Macnab criteria, and logistic regression analysis was performed to determine the independent influencing factors of the treatment efficacy of PETD.

RESULTS

The differences between the two surgical groups were statistically significant in terms of operation time (P<0.001), bleeding (P=0.005), and C-arm X-ray exposure times (P<0.001), and the above indexes were higher in the PETD group; however, there were no statistical differences in terms of improvement in functional scores (P>0.05) and clinical efficacy (P>0.05) between the two groups. BMI≥25 kg/m2 (P=0.001), severe disc degeneration (P=0.003), and operation time ≥60 min (P=0.003), severe disc degeneration (P=0.003), and operation time ≥60 min (P=0.036) were independent risk factors for the outcome of PETD.

CONCLUSION

The clinical effectiveness of PEID and PETD in treating LDH is comparable, and each has its own advantages. While PETD is more technically demanding, it does not yield superior results. Obesity, severe disc degeneration, and prolonged surgery are risk factors for the treatment efficacy of PETD.

Clinical effects and biological mechanisms of exercise on lumbar disc herniation

Lumbar Disc Herniation (LDH) is a syndrome in which lumbar disc degeneration, rupture of the annulus fibrosus, and herniation of the nucleus pulposus irritate and compress the nerve roots and cauda equina, resulting in the main manifestations of lumbar pain and/or lower extremity pain. There is evidence in various clinical areas that exercise is effective in treating LDH, and exercise intervention for more than 2 weeks reduces disease activity in LDH. However, the mechanism of exercise's action in reducing disease activity in LDH is unclear. In this article, we first summarize and highlight the effectiveness of exercise in treating LDH and provide guideline recommendations regarding exercise type, intensity, frequency, and duration. Then, we integrate the existing evidence and propose biological mechanisms for the potential effects of exercise on neuromechanical compression, inflammatory chemical stimuli, and autoimmune responses from the perspective of LDH pathogenesis as an entry point. However, a large body of evidence was obtained from non-LDH populations. Future research needs to investigate further the proposed biological mechanisms of exercise in reducing disease activity in LDH populations. This knowledge will contribute to the basic science and strengthen the scientific basis for prescribing exercise therapy for the routine clinical treatment of LDH.
