Reliability and validity of shoulder function outcome measures in people with a proximal humeral fracture
Abstract Purpose : Investigate test -- retest reliability and validity of five shoulder outcome measures in people during their active rehabilitation after a shoulder fracture . Method : This prospect i ve longitudinal study assessed shoulder function in 20 people ( 16 women , mean age 68.1 years ) with surgical or conservative management at 6 , 12 and 13 weeks post proximal humeral fracture using three patient-reported ( Disabilities of Arm , Shoulder and H and ; Oxford Shoulder Score ; Subjective Shoulder Value ) and two clinician-administered ( Constant Score ; UCLA Shoulder score ) outcome measures . Results : Content analysis categorised items into multiple domains of functioning for each outcome measure . Construct validity testing between measures found moderate to strong correlations ( r = 0.43–0.92 ) . Longitudinal validity ( responsiveness ) , represented by correlations between change scores , was moderate to strong ( r = 0.44–0.83 ) . Although ICCs2,1 for test – retest reliability ranged from 0.75 to 0.93 , Limits of Agreement between measurements were relatively wide ( 10–23 % of available range of scores ) . Minimal clinical ly important difference estimates varied between anchor- and distribution-based methods . Conclusions : The five outcome measures assessing shoulder function provided values for reliability and validity that meet measurement requirements for use in groups of people after a proximal humeral fracture . However , the use of these outcome measures might be limited by low absolute agreement between measurements and their content covering multiple domains of functioning . Implication s for Rehabilitation Linking the International Classification of Functioning , Disability and Health ( ICF ) to the content of common shoulder function outcome measures showed that multiple domains of functioning are combined into a single score . This might not be preferred for measurement of the single construct of “ shoulder function ” . Currently available shoulder function outcome measures may not be sufficiently reliable to monitor change in an individual after a proximal humeral fracture during the rehabilitation phase
