The Shoulder Function Index (SFInX): a clinician-observed outcome measure for people with a proximal humeral fracture

摘要

BackgroundProximal humeral fractures are amongst the most common fractures. Functional recovery is often slow and many people have ongoing disability during activities of daily life. Unidimensional measurement of activity limitations is required to monitor functional progress during rehabilitation. However, currentshoulder measures are multidimensional incorporating constructs such as activities, range of motion and pain into a single scale. Psychometric information of these measures is scarce in this population, and indicate measurement issues with reliability. Therefore, the aim was to develop the clinician-observed Shoulder Function Index (SFInX), a unidimensional, interval-level measure of ‘shoulder function’ based on actual performance of activities, reflecting activity limitations following a proximal humeral fracture.
