Shoulder strength testing: the intra- and inter-tester reliability of routine clinical tests, using the PowerTrack II Commander
Shoulder & Elbow, 04/18/2012
Dollings1 H et al. – The findings obtained in the present study suggest that using the methods employed in the population investigated demonstrated good to excellent intra– and inter–tester reliability for the measurement of shoulder strength. The standard errors of measurements (SEM) and smallest detectable difference (SDD) findings provide guidance for values that may be considered as a real change in strength.
