Arm && Interventions

Group	Intervention	Description
Yoga arm	Yoga arm	Patients with Schizophrenia will undergo 12 sessions of yoga. According to randomization one group of patients will start yoga immediately after recruitment ,whereas another group will go into wait list for 12 weeks after which they will also undergo Yoga treatment.

Primary Outcome Measures

Name	Time	Method
Improvement in negative symptoms in patients with schizophrenia	At the end of 12 weeks of yoga	Schizophrenia patients receiving yoga as add-on treatment will have significant improvement in negative symptoms after yoga therapy compared to those in the wait-list group as reflected by a greater decrease in Scale for Assessment of negative symptoms score. This scale measures negative symptoms on a 25 item, 6-point scale. Items are listed under the five domains of affective blunting, alogia, avolition/apathy, anhedonia/asociality, and attention. A higher score indicates greater severity.

Secondary Outcome Measures

Name	Time	Method
fMRI changes	At the end of 12weeks	Schizophrenia patients receiving yoga will have higher activation in Medial prefrontal cortex after yoga therapy compared to baseline and compared to those in the wait-list group at 12 weeks.
