Abstract
BACKGROUND: Office workers who need to use a computer while maintaining a static position for prolonged periods have more chance of having low back pain (LBP). OBJECTIVE: The objective of the study is to investigate the effect of yoga on stress, anxiety, depression, and spinal mobility in computer users with chronic LBP (CLBP). MATERIALS AND METHODS: In this randomized control trial, eighty computer users (42.6 ± 8.45 years of age; suffering from CLBP since 5.20 ± 3.01 years; 51 males and 29 females) who use a computer for their professional work, recruited from Bengaluru, India, were randomized into two groups: yoga group (n = 40) and physical exercise group (n = 40). The yoga group practiced an integrated module comprising yoga postures and mindfulness meditation, and the physical exercise group practiced physical exercise designed for LBP (1 h/day, 3 days/week for 16 weeks). Assessments of dial-type goniometer and Depression Anxiety Stress Scale-42 were performed at baseline, after 8 weeks, and after 16 weeks. RESULTS: Stress, anxiety, and depression scores were significantly lower in the yoga group as compared to the physical exercise group at 16 weeks (P < 0.001), whereas spinal flexion (P < 0.001), spinal extension (P < 0.001), right lateral flexion (P = 0.001), and left lateral flexion (P = 0.007) scores were significantly higher in the yoga group as compared to the physical exercise group at 16 weeks. CONCLUSION: Yoga is more effective in reducing stress, anxiety, and depression and improving spinal mobility in computer users with CLBP than physical exercise designed for LBP.
