Summary

The study examines (1) the effects of active anodal (facilitatory) tDCS and yoga combined intervention on cognitive function, clinical symptoms, and quality of life domains (social function and physical wellbeing) in psychosis, and (2) the neurophysiological mechanisms underlying the effects induced by the combined intervention.

Conditions

Interventions

DEVICE

Active tDCS

Active tDCS will be applied using a wearable stimulator (LifTid) with a constant stimulation intensity of 1.2 mA for 20 minutes. The device has been designed for anodal stimulation targeting DLPFC using the F3 (anode) to F4 (cathode) montage.

DEVICE

Sham tDCS

Sham tDCS will be performed using the same device but without stimulation. During the yoga training, all participants will wear the device and a facilitator will turn on the stimulation for participants receiving a-tDCS-Y intervention, and pretend to turn on the stimulation for participants receiving s-tDCS-Y intervention after the first 10-minute section.

BEHAVIORAL

Yoga

Yoga will be based on the basic theory and research of the foundation of Hatha yoga. Participants will cultivate the learning of yoga through various kinds of activity, such as breathing control, body postures, and relaxation. The yoga is designed to create an overall effect on the body and mind through strength training and stretching with a mindful sensation. Each 1-hour intervention session contains reviewing the last week self-practice, breathing practice and warm-up (10 minutes), posture sequences (40 minutes), relaxation (5 minutes), reflection and feedback (5 minutes). Video clips will be provided through social media apps (i.e., WhatsApp, WeChat) to enable home-based practice at least twice weekly. A logbook will be distributed to the participants for their record of self-practice and will be reviewed weekly by the intervention facilitator.
