Abstract
To investigate the relationship between age and the Constant score: A formula to correct for age.
Method and results Healthy volunteers from the King’s College Hospital population with no previous shoulder disease were assessed using the constant score.270 healthy shoulders were tested. The subjects’ ages ranged from 16 to 83 with a mean age of 44.3. The scores ranged from 60 to 100 with a mean score of 82.3. Pearson correlation analysis gave us a trend or slope of −0.1.
Corrected score= actual score −[(age-44)( −0.1)].
Conclusion We concluded that the constant score decreases with age at a rate of one point per decade and that in order to compare subjects’ scores in a standardised way this correction should be applied.
