Cephalalgia : an international journal of headache

Pressure pain detection threshold and pressure pain tolerance threshold were measured in the temples and on the fingers in 40 healthy volunteers, equally distributed as to sex and handedness. Lower pressure pain thresholds were found over the temporal muscle than in a neighbouring temporal location without interposed myofascial tissue (p less than 0.001), indicating that nociception from myofascial tissue contributes to the pressure pain threshold. ⋯ Finally, pressure pain thresholds were lateralized in dextrals but not in sinistrals. The information that can be obtained from pressure pain detection and tolerance thresholds is discussed and examination of both threshold types is recommended in future studies.
