Abstract		Background. Rupture of the rofator cuff (RC) is one of the most frequent cause for fhe pain in shoulder joint. Chronic rupture of RC leads to muscle atrophy because of inactivity. The purpose of this sfudy was fo show fhe contribution of electromyography (EMG) at proceeding of patients after RC reconstrucfion. Methods. Retrospective investigation was done on 51 patient, operated because of RC rupture at Department of Orthopedic Surgery and Sports Trauma af Celje General Hospital between 1992 and 1996. The EMG analysis of m. supraspinatus and m.. infraspinafus was performed on operafed shoulder and the healfhy shoulder of the same person. The results of EMG analysis were compared wifh the resulfs of treatment evaluated wifh Constant score and with operatively confirmed tear size. Resulfs. A difference in reduction of the interference pattern as compared to the opposife side was esfablished with semiquanfitative EMG analysis of m. supraspinatus and m. infraspinatus, which was statistically significant for m. infraspinatus (p=0,0038). Positive correlation was found between the reduction of inferference pattern and fear size (p<0,05 for both muscles). Also, a positive correlation was noted between the reduction of interference pattern and the results of treatment evaluated with Constant score (p<0,05 for both muscles). Conclusions. EMG analysis of the rotator cuff muscles contributes to evaluation of shoulder funcfion and/or regeneration of disuse muscle atrophy. At the same time it also enables to exclude or confirm additional neurological or muscle pathology.
