Abstract
This study aimed to observe the effects of head massage on electromyography (EMG) biofeedback,
blood pressure and heart rates in 16 volunteers who worked as massage therapists. The participants were
selected using the purposive sampling from those who were 30-50 years old, had no pain in the back and
neck and could participate until the end of the project. On average, the participantsû age, weight and height
were 40.5 ± 8.91 years, 58.4 ± 8.87 kilograms, and 157.3 ± 3.56 centimeters, respectively; and they worked
32.2 ± 2.74 hours per week and had 25.8 ± 21.83 months of work experience. Each of the subjects received
Indian head massage (Shirobhyanga) for 60 minutes, including head massage and acupressure in the supine
position for 30 minutes and head-neck-back massage as well as acupressure in the prone position for 30
th
minutes. Data on EMG biofeedback, blood pressure and heart rates were recorded before, during (30 minute)
th
and after massage (60 minute), and were then analyzed using the one-way analysis of variance for the data
on repeated measurements. The significance level was set at 0.05. Results showed that 60-minute Indian head
massage could significantly reduce the levels of EMG biofeedback heart rate and systolic blood pressure (p
= 0.000), but made no change in diastolic blood pressure (p = 0.507). Thus, Indian head massage can relax
the body and mind.

Key words: head massage, electromyography biofeedback, blood pressure, heart rate
