Abstract

|
Objective:This study was conducted to analyze the psychological factors which influence myofascial pain syndrome and to evaluate whether the electromyographic study on the myofascial trigger point in shipyard workers satisfied the diagnostic criteria of myofascial pain syndrome.
Method: We studied 61 patients who were employed in the shipbuilding industry and diagnosed myofascial pain syndrome. We investigated them using the Minnesota Multiphasic Personality Inventory (MMPI) and the visual analogue scale (VAS) and also obtained spontaneous electrical activity (SEA) by electromyographic study on myofascial trigger point.
Result: Mean VAS of subjects was 5.88. On the MMPI profile, the patients scored highest in psychopathic deviate, and then in hypochondriasis, depression and hysteria, in that order. The correlation of the VAS with results of electromyographic study and with the MMPI were not significant. In the electromyographic study, 19 patients out of 61 (31%) showed initial positive deflection on spontaneous electrical activities.
Conclusion: This study suggested that considering the psychosocial aspect of myofascial pain syndrome, as well as organic aspects in hard manual labor such as shipyard work might be useful for treatment.
