  Purpose

Cognitive impairment is a key disabling feature of SZ. The impairment affects functional outcome and employability, resulting in increased burden. Currently, medications offer only modest benefits for the cognitive dysfunction. Hence, non-pharmacological interventions are worth consideration. Yoga is known to enhance cognitive abilities in healthy persons. Our preliminary studies have shown for the first time that there may be remarkable improvement in selected cognitive domains among outpatients with SZ. The improvement is unlikely to be due to rater bias, as they were noted using a computerized neurocognitive battery. Since our preliminary studies involved an open trial, it is necessary to conduct more controlled studies. To evaluate our results further, we propose to test the effectiveness of yoga supplementation using a controlled single blind design in India. Outpatients with SZ (N=258) undergoing treatment at a large academic center in New Delhi, India will be randomly assigned to one of the three groups- yoga training (YT, N=86), physical exercise (PE, N=86) or treatment as usual (TAU, N=86). The YT group will undergo 21 days yoga supplementation, while the PE group will complete a 21 day systematic physical exercise training regime. The third group will have no such supplementation. Cognitive state, symptom severity and overall function will be assessed at four time points: just before, immediately after, three months later and six months after completion of YT/PE supplementation. The evaluations will be conducted by raters blind to group status.

Hypotheses:

  1. Yoga enhances attention, as well as related cognitive function among persons with schizophrenia.
  2. Yoga has beneficial effects on the short term functional outcome of schizophrenia

Primary Outcome Measures:
  • Cognitive assessment [ Time Frame: Changes in cognition from baseline to 21 days intervention, three months and after six months after completing intervention will be assessed. ] [ Designated as safety issue: No ]

    The key assessment will be based on an efficient, validated computerized battery called the Computerized Neurocognitive Battery (CNB) {Gur, 2001

    #38} {Gur, 2001} . The assessment will be supplemented by the Information subscale of Post-graduate Institute Battery of Brain Dysfunction (PGI) (as an indirect assessment of intelligence) {Pershad, 1990} and the Trail Making Test {Horton, 1979}, a pen and paper measure of working memory.



Secondary Outcome Measures:
  • Symptom assessment General Functioning [ Time Frame: Changes in symptoms from baseline to 21 days intervention, three months and after six months after completing intervention will be assessed. ] [ Designated as safety issue: No ]
    Symptom assessment: The positive and negative symptoms will be assessed using the Scale for the Assessment of Negative Symptoms (SANS) and Scale for the Assessment of Positive Symptoms (SAPS) at baseline, three months and six months. After yoga/physical exercise SAPS and SANS will be done for the previous three weeks only. . General Functioning: The Global Assessment of Function Scale {Endicott, 1976} will be used to measure the overall functioning of participants.


Other Outcome Measures:
  • Independent Living Skills Survey [ Time Frame: Changes in living skills from baseline to 21 days intervention, three months and after six months after completing intervention will be assessed ] [ Designated as safety issue: No ]
    Independent Living Skills Survey {Wallace, 2000 #92}: The basic functional living skills (Activities of Daily Living, ADL) of participants will be measured by Independent Living Skills Survey (ILSS) {Wallace, 2000 #92} at every cognitive assessment point.


Estimated Enrollment: 258
Study Start Date: August 2010
Estimated Study Completion Date: July 2015
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Yoga Training Group
Yoga Training: Participants will be imparted yoga training for twenty-one days, for one hour a day. This will include postures or Asanas (exercises) and Pranayam (Breathing protocols).
Behavioral: Yoga Training
Participants will be imparted yoga training for twenty-one days, for one hour a day. This will include postures or Asanas (exercises) and Pranayam (Breathing protocols). The training starts with 'Om' chanting followed by warm up exercises and then breathing exercises. The Breathing exercises (Pranayama) are practiced before practice of Asana.
Placebo Comparator: Treatment as Usual Group
Participants who will continue in the department with clinical treatment as usual. No supplementation will be provided
Active Comparator: Physical Exercise Group
Physical Exercise: This group will take part in a general physical exercise program incorporating simple physical exercises for one hour daily, including Saturdays. The schedule will include fifteen minutes of brisk walking followed by light exercises.
Behavioral: Physical Exercise
This group will take part in a general physical exercise program incorporating simple physical exercises for one hour daily, including Saturdays. The schedule will include fifteen minutes of brisk walking followed by light exercises adapted from the National Fitness Corps - Handbook for Middle High and Higher Secondary Schools as used by Duraiswamy et al. (2007).
