Effect of yoga and mindfulness meditation on quality of life in computer users with chronic low back pain: A prospective randomized active control trial

Abstract

Background: Computer professionals are more prone to chronic low back pain (CLBP) as compared to the normal population. It has been reported that the 1-year prevalence of low back pain (LBP) was 23%38% in the normally active population, while it was 31%54% in computer users. Objective: To investigate the effect of yoga and mindfulness meditation on the quality of life (QOL) of computer users with CLBP. Materials and Methods: Eighty computer users (42.6 ± 8.45 years of age; suffering from CLBP since 5.20 ± 3.01 years; 51 males and 29 females) were recruited from Bengaluru, India. Participants were randomized into two groups: Yoga and mindfulness meditation/YM group (n = 40) and physical exercise/PE group (n = 40). The YM group practiced an integrated module comprising yoga postures and mindfulness meditation, and the PE group practiced PE designed for LBP. Both groups practiced 1 hour daily, 3 days a week for 16 weeks. WHO QOL-BREF and spinal flexibility (Straight Leg Raising [SLR]) were assessed at baseline and after 8 and 16 weeks. Results: Results of repeated measures-analysis of variance test showed that the scores on QOL physical health (diff = 12.43%, P < 0.001), psychological health (diff = 11.9%, P < 0.001), social relationships (diff = 15.66% P < 0.001), and environment (diff = 17.37% P < 0.001) were significantly higher in YM group as compared to PE group at the end of 16 weeks. Similarly, the scores on the SLR right leg (diff = 12.97%, P < 0.001) and SLR left leg score (diff = 11.71%, P < 0.001) were significantly higher in the YM group as compared to the PE group at the end of 16 weeks. Conclusion: Yoga with mindfulness meditation is significantly more effective in improving QOL and spinal flexibility in computer users with CLBP as compared to PE designed for LBP.
