Subjects perform yoga techniques for 1 month. A booklet and recorded video was provided to read and follow the steps. Pre-treatment assessment was done before start of yoga therapy. Post treatment evaluation was done by assessing sleep through Pittsburgh Sleep Quality Index Questionnaire and QoL via SF-36 Questionnaire.

Primary outcomes

  1. Physical function

    Time frame: End of 4 weeks

    Short Form-36 Health Survey (SF-36) questionnaire. The questionnaire assesses health-related quality of life across eight domains. Each domain is transformed to a 0-100 scale, where 0 represents the worst possible health status and 100 represents the best possible health status. Higher scores indicate better health-related quality of life.

  2. Sleep

    Time frame: End of 4 weeks

    The Pittsburgh Sleep Quality Index (PSQI) is a standardized self-report questionnaire developed to assess subjective sleep quality. It consists of 19 self-rated items, which are combined into 7 component scores. Outcome Measure: Pittsburgh Sleep Quality Index . It is a validated self-administered questionnaire that assesses subjective sleep quality over the preceding month. It comprises 19 self-rated items grouped into seven components, each scored from 0 to 3. The component scores are summed to obtain a global score ranging from 0 to 21, where 0 represents the best sleep quality and 21 represents the poorest sleep quality. A global score greater than 5 is indicative of poor sleep quality and clinically significant sleep disturbance.
