The purpose of this study was to investigate the effects of lumbar stabilization and sling exercise on visual analogue scale (VAS), Korean Oswestry Disability Index (KODI), and stability index (ST) in patients with chronic lower back pain (CLBP). This study included participants with a VAS scale of 6 or higher and a KOD of 20-40%. They were randomly divided into a mat group (n=15) to perform lumbar stabilization exercises and a sling group (n=15) to perform sling exercises, and then they underwent a four-week experiment. The experimental results of this study were as follows: the VAS and KODI showed a statistically significant difference (P<.05) and a larger effect size within each group after the intervention, it exhibited no statistically significant difference between the two groups (P>.05). There were significant differences in ST before and after intervention in each group (P<.05), however there was no significant difference between the groups. The present study suggest that the effects of lumbar stabilization exercise and sling exercise are similar.

The Purpose of this study was to determine the effects of sciatic nerve mobilization on pain and lower back muscle strength in female patients in their 40s who have been diagnosed with lumbar radiculopathy. Using a simple blinded method, 20 female patients with neuropathy in the nerve segments between L4-S1 were randomly divided into one group (n=10) that would undergo sciatic nerve mobilization, and another group (n=10) that would perform lower back segment stabilization exercises. The two groups attended 3 sessions per week, with each session taking 30 minutes, for a duration of 4 weeks. In the preliminary examinations, the pain index as well as the isometric muscle strength of the lower back extensor and flexor muscles were measured. After the passing of 4 weeks. The same method of measurement was used for the concluding examinations. Comparison of the pain indices in the two groups revealed that they both experienced a statistically significant decrease, and further inspection revealed that the there was a more substantial difference in the sciatic nerve mobilization group. Results of comparing changes in the Isometric Muscle Strength lower back muscle and bending muscle by group, In comparison between groups, the isometric strength of the lower back extensor showed a more significant difference in the sciatic nerve mobilization group (p <.05). Conclulsion, it can be inferred that application of sciatic nerve mobilization has a positive effect on the pain index and isometric muscle strength of the lower back in female patients with lumbar radiculopathy in their 40s.
