Background / objective Shoulder strength measurement of the is mandatory in the evaluation of shoulder function in patients with shoulder pa-thology. We can use observer-based measurements with the digital dynamometer or self-assessment scales with special questions about elevation of different weights in everyday activities. Patient self-assessment is simple and rapid, it requires no observer and special equipment. This method may replace complex observer-based measurements. The purposes of this study were to compare two different shoulder strength evaluation methods and to determine whether the patient-based evaluation equals the observer-based measurements. Materials and methods In the hospital, 108 patients with a rotator cuff injury were prospectively evaluated. Observer-based measurements of the shoulder muscle strength were performed using a digital dynamometer for both injured and healthy shoulders. For the patient-based evaluation we used the strength subscale (three questions) from the shoulder joint specific self-assessment Simple Shoulder Test instrument. For statistical analysis we used observer-based measurements of the strength in kilograms (means of three measurements), results of separate three questions and the total shoulder strength score. The reliability of observer- and patient-based assessments was determined and the two strength evaluation methods were compared. Results The intraclass correlation coefficient for intra observer reliability was 0.951. The intraclass correlation coefficients for test–retest reliability of three separate questions were 0.896, 0.896, 0.887, and the total strength score was 0.952. Observer-based measurements showed a moderate correlation with the results of separate three questions (rho = 0.527, p < 0.001; rho = 0.632, p < 0.001; rho = 0.527, p < 0.001) and with the total shoulder strength score (rho = 0.702, p<0.001).Conclusion Patients can evaluate their shoulder strength in a reliable way using questions from the strength subscale of the self-assessment Simple Shoulder Test. The accuracy of these measures is not equal to the observer-based measures using a digital dynamometer. |
