The effect and durability of combined occupational education and yoga Intervention on pain and ‎trunk extensor muscle endurance of male employees of Iran khodro Diesel Company with non-‎specific chronic low back pain

Chronic low back pain is one of the primary disorders in work and industrial environments. This study aimed to investigate the effect and follow-up of the combined protocol of occupational education and yoga on the pain intensity and endurance of trunk extensor muscles.

The current study is a semi-experimental type with a pre-test-post-test design with follow-up. The participants were 24 men (employees of Iran Khodro Company) suffering from non-specific chronic low back pain, who were randomly selected into 2 equal groups of 12 people using available samples. This study evaluated pain with a visual analog scale and endurance of extensor muscles with the Bering-Sorenson test. Then, the experimental group implemented a combined protocol of occupational education and yoga for ten weeks. The control group only participated in the pre-test and post-test. After collecting the data, the statistical method of composite covariance analysis with a significant level (α ≤ 0.05) was used to analyze the data.

The findings showed that occupational education and yoga Intervention had a significant effect ‎on pain, and trunk extensor muscle endurance subjects with non-specific chronic low back pain ‎‎ (P≤‎‏0.05‏‎). ‎

Considering the effectiveness of the combined protocol of occupational education and yoga on the pain and endurance of extensor muscles, therapists are advised to consider the combined protocol of occupational education and yoga in compiling their training programs.
