Study shows acceptable reliability for procedures measuring shoulder range of motion
Researchers found acceptable reliability for all procedures which measured shoulder range of motion and internal and external rotation strength, according to study results.
Researchers measured shoulder range of motion with goniometer and inclinometer and isometric strength with a hand-held dynamometer in different patient and shoulder positions for 30 healthy individuals. Researchers determined the relative reliability by intraclass correlation coefficients while absolute reliability was quantified by standard error or measurement and minimal detectable change. Dependent t test was used to analyze systematic differences across trials or between testers and repeated-measures analysis of variance differences.
Regardless of patient or shoulder position or the equipment used, the researchers found good to excellent reliability for internal and external range of motion and isometric strength measurements. However, there were systematic differences across trials or between testers for some measurements, such as the patient’s position and equipment used which results in different outcome measures.
