| Outline of Final Research Achievements |
This study performed a quasi-experimental design, to examine intervention effects against pain by gum chewing in adults. The healthy subjects chewed gum to the rhythm of a metronome for sixty minutes during the experiment. Interventional effect was quantitatively assessed as follows: each volume of stress substances in saliva, the amount of emotional sweating and subjective estimates of pain. Experimental pricking pain was intermittently induced at right forearm of subjects with the portable peripheral neural stimulator every twenty minutes. These results reveal that the chewing movement effect by a regular rhythm to pain would appear 20 minutes on the objective pain responses of acute stress substances in saliva after the chew beginning. Therefore, gum chewing would be useful for temporary pain relief for pricking pain in adults.
