Epidemiology of Chronic Shoulder Pain Among Adult Patients in a Tertiary Care Hospital in South India

Abstract

Introduction Chronic shoulder pain (CSP) is a significant medical and socioeconomic problem that hinders daily living activities, creating a burden on the individual and society. An epidemiological study will help to find out the risk factors and their impact, thereby giving medical practitioners and policymakers the necessary tools to tackle the problem. Materials and methods This is a cross-sectional study conducted in a tertiary care hospital in South India over a period of four years from 2018 to 2021 using a structured questionnaire, clinical and radiological examination, and visual analog score (VAS). The data were analyzed using SPSS software. Results A statistically significant correlation was found between CSP and increasing age, occupational risk factors like vibrations, repetitive movements, lifting heavy objects, repetitive lifting of the arm above the shoulder and sitting in the same posture for a prolonged time, and work stress. Vitamin D deficiency and diabetes mellitus were found to increase the risk of shoulder pain, smoking, and alcoholism. There was a higher incidence of rotator cuff pathology and frozen shoulder among those who had CSP. Conclusion CSP affects the quality of life and the productivity of the patients. Reducing the physical and psychosocial risk factors is the key to decreasing its prevalence. Maintaining a healthy lifestyle and a good working environment is very essential.
