ABSTRACT NUMBER: ESOC2026A830 MULTIDIMENSIONAL IMPACT OF POST-STROKE SHOULDER PAIN ON MOTOR FUNCTION, PSYCHOLOGICAL STATUS, AND QUALITY OF LIFE IN CHRONIC STROKE SURVIVORS

Abstract Background and aims Post-stroke shoulder pain (PSSP) is a common and disabling complication that adversely affects upper extremity function, emotional well-being, and quality of life. Despite its prevalence, the multidimensional impact of PSSP in chronic stroke remains underexplored. This study examined the effects of PSSP on upper extremity motor function, kinesiophobia, anxiety, and quality of life in individuals with chronic stroke. Methods Fifty-three adults with chronic stroke were recruited from an outpatient physiotherapy clinic. Demographic and clinical data were recorded. Pain severity was assessed using the Numerical Pain Rating Scale and the Shoulder Pain and Disability Index (SPADI). Upper extremity motor function was evaluated with the Arm Motor Test, kinesiophobia with the Tampa Scale of Kinesiophobia, anxiety with the Beck Anxiety Inventory, and quality of life with the Stroke-Specific Quality of Life Scale. Correlation analyses and stepwise regression were performed to identify significant associations and predictors of disability. Results Higher shoulder pain was significantly associated with reduced motor function (p<0.01), increased anxiety (p<0.01), and lower quality of life (p<0.01), but not with kinesiophobia. Pain severity decreased over time since stroke (p<0.01). Women reported higher pain levels than men (p<0.05). Regression analysis indicated that activity-related pain was the strongest predictor of SPADI scores, explaining 38% of the variance. Conclusions PSSP has significant functional and psychosocial consequences in chronic stroke survivors. Comprehensive assessment and early targeted interventions may improve motor recovery and enhance quality of life.
