THU0499 RISK FACTORS FOR SHOULDER PAIN PERSISTENCE IN ROTATOR CUFF DISORDERS

Abstract

Background: A large proportion of patients with atraumatic painful shoulder have an unfavorable outcome with long-term disability (1). Predictors of no recovery in patients with shoulder disorders were identified previously: repetitive overhead activity in sport and work (2) duration of complaints, somatization, low social support, older age, unemployment, musculoskeletal comorbidity, recurrent complaint (3,4). Objectives: To identify the risk factors for over 6 mounth pain persistence in patients with rotator cuff disorders Methods: Our prospective study included 51 hospitalized patients with atraumatic shoulder pain. The assessment was clinical and shoulder MRI for confirmation of rotator cuff disorders. We have studied the influence of the patient's characteristics and the influence of the condition's characteristics for pain persistence. Statistical analysis was performed in SPSS-18, p<0.05 was significant. Results: No significant correlations were found between pain persistence and age, gender, smoking status, occupational overuse, physical demands before the onset of pain, marital status, continuous pain, lesions on shoulder MRI. The association with the following elements is statistically significant for pain persistence: opposite shoulder previously affected (p=0.01), diabetes mellitus(p=0.04), insidious onset(p=0.004), the high educational level(p=0.02), physical therapy(p=0.03), local injection (p=0.08). Using multinominal regression we observed only acute onset of the pain shoulder (RR=7.1) and physiotherapy treatment (RR=0.1) with p=0.026. Conclusion: The factors that determine the shoulder pain persistence are non-specific and can be sometimes psyhosocial, local, physical or other comorbidities like diabetes.
