The present study will be conducted at the Department of Physiology in collaboration with the Department of Psychiatry of R.D. Gardi Medical College, Ujjain, Madhya Pradesh.

This double-blind randomized controlled trial will remotely enroll 60 subjects. Each participant will complete 20 stimulation sessions at a rate of 3-5 sessions per week. Each session will be 30 minutes on the day of usage. The study will be randomized with a 1:1 active; or sham control allocation. Endpoint analysis will be performed upon completion of the study.
