Participants, settings: 143 subjects were recruited. Of these, 121 subjects (76 females and 45 males) were randomly assigned using the lottery method to four groups receiving auditory (n = 30), visual (n = 30), combined GSR BF (n = 30) and control group (n = 31), respectively. Intervention: Each subject (except control group) received 15 sessions of BF for 30 min each in an isolated room in the physiotherapy outpatient department.
