The influence of age and unreported symptoms on the Oxford Shoulder Score

Background One potential limitation of interpreting the Oxford Shoulder Score (OSS) in longitudinal studies is that the observed score may be influenced by age and other variables, which may change over time. The purpose of the present study was to investigate the influence of increasing age and unreported non-shoulder upper limb and neck symptoms on the OSS. Methods We collected OSS data from a sample of our ethnically diverse local population. All subjects indicated whether they suffered from any neck, shoulder, elbow or wrist symptoms for which they had not sought a medical opinion.
