Abstract: Chronic shoulder pain present complex pathomechanical situations, frequent difficulties in identification of the pain causing factors leading to lack of effectiveness in treatment. Thus the purpose of this study is to identify the role of neurophysiological changes altering pain sensitivity leading to hyperalgesia and allodynia in such patients. Pressure pain threshold values of the affected side of patients were compared to the unaffected side and to controls and were analysed statistically, significant difference in the readings were noticed pointing towards central nervous system playing a role and leading to central and peripheral sensitization
