The normalization of data in the Constant-Murley score for the shoulder. A study conducted on 563 healthy subjects.
The study was conducted in order to evaluate the theoretical design of the Constant-Murley system and to reveal any difficulties in obtaining data when it is used in 563 subjects not affected with shoulder pathology. The total mean score for the subjects examined was 85.2 points (minimum 75, maximum 100 points). Values revealed a decreasing trend beginning at 50 years of age for men and 30 for women. Only 4 subjects achieved a maximum score of 100. The measurements taken allowed us to elaborate a reference table based on sex and age, which was required to calculate the correct score. These values differ from those reported by the inventors of the system and they reveal the need to compile personal tables for the normalization of scores.
