Shoulder Pain is the most common problem in workers exposed to repetitive shoulder activity in their occupation. The risk factors for shoulder pain among sweepers are used upper limb frequently for sweeping and prolonged duration of sweeping with the long handled heavy brooms, which increases the demand on the muscles, ligaments and soft tissues around shoulder joint. The Shoulder Pain and Disability Index (SPADI) is a valid and reliable questionnaire used in shoulder disorders. The purpose of this study was to test the convergent validity and the reliability of the SPADI
Aim and Objectives of the study: Rule out reliability and validity of SPADI
Materials and Methods: A total of 200 Sweepers with shoulder pain were enrolled in the study. The SPADI and the Health Assessment Questionnaire (HAQ) were completed by all the participants. Pain was measured using the Visual Analogue Scale (VAS) during the active range of motion. Reliability was measured by internal consistency and test-retest reliability. Internal consistency was determined by calculating Cronbach’s alpha value. Convergent validity was examined by correlating the SPADI questionnaire with the VAS and HAQ scales
Results: Prevalence of shoulder pain among sweepers of Surat and Bardoli city was 49%. Cronbach’s alpha value for the SPADI was found to be 0.77. The item - total correlation of the SPADI was 0.841- 0.971. The ICC for the SPADI was 0.064, which is towards stability. r=0.734 for SPADI and HAQ (TOTAL). r=0.718 for SPADI and VAS.
Conclusion: The study shows the sweepers have shoulder pain but low back pain and knee pain are more prevalent than shoulder pain. The results of the present study suggest that the SPADI is a valid and reliable instrument to assess shoulder pain in Surat Patients.
