KY Protocol Components

Home-Based Kundalini Yoga for Hypertension: Multi-Centre RCT DESIGN: Multi-centre RCT; yoga (n=96) vs. usual care (n=95). POPULATION: N=191 primary care patients with diagnosed hypertension (mean age 64.7, SD=8.4, 52% women). INTERVENTION: Short home-based Kundalini yoga programme, 15 min twice daily for 12 weeks. ADHERENCE: 75/96 (78%) yoga participants practiced at least 9/12 weeks per yoga calendars. OUTCOMES: Standardized BP, QoL, stress (PSS), anxiety and depression (HAD). RESULTS: Both groups showed significant BP reductions. Yoga group showed significantly greater improvements in self-rated QoL and self-rated stress (p<0.05), anxiety, and depression vs. control. NOTE: This is the main multi-centre trial from the Wolff hypertension series. Same protocol as Wolff 2013 pilot but in larger, multi-centre design. Specific exercises not enumerated in paper.
