Designing, validation, and feasibility of a yoga module for patients with ankylosing spondylitis

Ankylosing spondylitis (AS) is a chronic inflammatory disease that causes significant disability and reduced quality of life. Scientific studies on yoga have revealed its various health benefits in chronic conditions, including autoimmune diseases. However, whether yoga is feasible for AS patients or not is not studied. Further, no validated yoga module is available for AS patients.

This study intended to develop a yoga module for AS patients and investigated its feasibility of use.

The study was completed in three stages. In Stage I, six yoga experts prepared a list of 64 yoga practices based on the classical and contemporary yogic literature review. Of these practices, 41 were included in the designed yoga module. In Stage II, 41 experts with a minimum of five years of experience in yoga therapy were invited for yoga module validation. The usefulness of the practices was rated by experts on a 3-point scale (1: not at all useful, 2: moderately useful, and 3: very much useful). The Lawshe content validity ratio (CVR) method was used for the content validity of the yoga module. Practices with a CVR score of > 0.3 were retained in the final yoga module. In Stage III, a certified yoga instructor administered the validated yoga module to 19 AS patients (average age: 35.5 ± 10.7 years) thrice weekly for a month. Feasibility was assessed on the basis of the attrition rate, retention rate, attendance of the participants, and the subjective response on practical sessions using a structured checklist.

Of the 41 practices in the module, 31 had a CVR score of > 0.3 and were included in the final yoga module. Of the 25 participants, 19 (76%) completed the study while six dropped out (24%). Nineteen patients reported greater improvement in pain and flexibility. They found yoga relaxing and easy to practice. Most participants (65%) were able to practice a minimum of 30 min/day.

The present study offers a validated yoga module consisting of 31 practices for AS patients. The results of the pilot suggested that the module is feasible, acceptable, and easy to practice for AS patients. We recommend that AS patients should practice this yoga module for a minimum of 30 min every day under the supervision of a yoga expert.
