Designing, validation, and feasibility of integrated yoga therapy module for chronic low back pain

Abstract

Context: Chronic low back pain (CLBP) is a significant public health problem that has reached epidemic proportions. Yoga therapy has emerged as one of the complementary and alternative therapies for CLBP. Aim: The present study reports the development, validation, and feasibility of an integrated yoga therapy module (IYTM) for CLBP. Settings and Design: This study was carried out at the SVYASA Yoga University, Bengaluru, South India. The IYTM for CLBP was designed, validated, and later tested for feasibility in patients with CLBP. Materials and Methods: In the first phase, IYTM for CLBP was designed based on the literature review of classical texts and recently published research studies. In the second phase, designed IYTM (26 yoga practices) was validated by thirty subject matter (yoga) experts. Content validity ratio (CVR) was analyzed using Lawshe′s formula. In the third phase, the validated IYTM (20 yoga practices) was tested on 12 patients for pain, disability and perceived stress at baseline and after 1-month of this intervention. Results: A total of 20 yoga practices with CVR ≥0.33 were included, 6 yoga practices with CVR ≤0.33 were excluded from the designed IYTM. The feasibility study with validated IYTM showed significant reduction in numerical pain rating scale (P = 0.02), Oswestry disability scale (P = 0.02), and Perceived Stress Scale (P = 0.03). Conclusion: The designed IYTM was validated by thirty yoga experts and later evaluated on a small sample. This study has shown that the validated IYTM is feasible, had no adverse effects and was useful in alleviating pain, disability, and perceived stress in patients with CLBP. However, randomized control trials with larger sample are needed to strengthen the study.
