Sudarshan Kriya Yoga and Cardiac Autonomic Control in Patients With Anxiety-Depression Disorders

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02828072

Brief Summary:
The effects of Sudarshan Kriya Yoga (SKY) on autonomic function in patients with anxiety-depression disorders is unknown. Thus, the authors will investigate cardiac autonomic control in a population of patients with anxiety-depression disorders which will undergo a specific SKY treatment.

Condition or disease Intervention/treatment Phase
Anxiety Depression Other: SKY therapy Drug: usual drug therapy Not Applicable

Detailed Description:

Several studies have demonstrated that adjuvant therapies as exercise and breathing training are effective in improving cardiac autonomic control (CAC) in patients with affective spectrum disorders. However, the effects of Sudarshan Kriya Yoga (SKY) on autonomic function in this population is unknown. To test the hypothesis that SKY training improves CAC, cardiorespiratory coupling and adaptive response of sympatho-vagal balance to orthostatic changes were evaluated in patients with anxiety and/or depression disorders.

The authors will enroll patients with a diagnosis of anxiety and/or depression disorders (DSM-IV) and they will divide them in two groups: 1) conventional therapy (Control) and 2) conventional therapy associated with SKY (Treatment) for 15 days. Anxiety and depression levels will be determined using quantitative questionnaires. For the assessment of CAC and cardiorespiratory coupling, cardiorespiratory traces will be analyzed using monovariate and bivariate autoregressive spectral analysis, respectively.
