Purpose: To investigate the effects of myofascial trigger-point(MTrP) massage to the neck, shoulder and upper back areas on autonomic tone, and to examine the psychological outcomes of MTrP massage.
Method: Forty subjects with a mean age of 27.5 years were recruited, initially matched according to age and sex, and then randomly assigned into either experimental- or control group. Subjects in the study group received MTrP massage on shoulder and upper back areas for 20 minutes while those in the control group were relaxed by lying quietly for the same period. A 5-minute cardiac inter-beat interval recording, blood pressure and subjective self-evaluations regarding emotional status as well as muscle tension with Visual Analogue Scale(VAS) were examine at the points of before and after MTrP massage. Autonomic function was measured, using time and frequency domain analysis of heart rate variability.
Results: Analysis of heart rate variability was showed a significant increase in parasympathetic activity(p=.01) following MTrP massage therapy. Additionally, both subjective emotional status and muscle tension were improved significantly (p<.01).
Conclusion: Based on the results above, We suggest that MTrP massage might have beneficial effects on
parasympathetic activity, emotional state and muscle relaxation.
