Résumé : Electromyographic signs of spasmophily have been found to be increased by patients suffering from functional low back pain (n=50), cervical pain (n=50) and painful shoulder (n=35) compared to control patients suffering from any other established osteoarticular painful disease of another region (n=50). Similarly electromyographic signs of spasmophily are increased by patients suffering from functional low back pain (n=50) compared to patients suffering from lumbarthrosis (n=50). In 40 classical spasmophilic patients HLA B 5, HLA B 12, HLA BW 17 and HLA BW 40 have been found to be less frequent than in a control population of 60 blood donors. This suggests that genetic factors related to the 6th chromosome might be implicated in the development of spasmophily.
