title: Effects of manual lymph drainage for abdomen on the brain activity of subjects with psychological stress.
abstract: [Purpose] The present study investigated the effects of manual lymph drainage for abdomen on electroencephalography in subjects with psychological stress. [Subjects and Methods] Twenty-eight subjects were randomly allocated to undergo a 20-min session of either manual lymph drainage or abdominal massage on a bed. [Results] Analysis of electroencephalograms from the manual lymph drainage group showed a significant increase in relaxation, manifested as an increase in average absolute, relative alpha activity and a decrease in relative gamma activity. [Conclusion] Our results suggest that the application of manual lymph drainage from the abdomen provides acute neural effects that increase relaxation in subjects with psychological stress.
