Modification of the Constant-Murley shoulder score-introduction of the individual relative Constant score

In a non-parametric comparison of the reciever operating characteristics the CSindiv shows the higher ability to discriminate between patients and healthy volunteers (p = 0.004). This indicates that the individual relative Constant score gives a more accurate view about the functional result for shoulder disorders. It is expected to be more reliable for larger and incoherent patient populations, because specific interindividual differences, regarding the patient's age, gender and constitution are eliminated as well as other individual physiological parameters.
