Pain threshold determining in the Umsa students from Iran, Syria, palestina, Iraq and Sudan writing with right and left hand

Abstract

We have performed our investigations in UMSA students of all courses both of medical and dental faculties from Iran (54), Syria (13), Palestine (18), Iraq (18), Sudan (18). There were 80 left-handers and 46 right-handers among them. Pain threshold was the lowest in the Iranians, then follow the students from Sudan, the Syrians, the students from Iraq, the Palestinians. Independently on the country left-handers possessed less pain threshold than the right-handers and this difference was maximally valuable in the Iranians. Also the left-handers had less pain threshold on their face left half while the dexters - on the right ones. This difference was maximally valuable in the students from Iraq. We do hope that given data can help in stress assessment in students from different countries (because pain can be considered as a stress marker), in their better adaptation to new life conditions, new mental and physical regimens.
