Joint looseness: a function of the person and the joint

In order to evaluate whether joint-looseness is a function of a particular joint and/or a characteristic of the person (a trait), 124 male and female subjects varying in age from 6 to 18 were tested. Evidence was found that joint-looseness is a trait. The validity of the trait measure was enhanced by finding significant negative correlations with age and performance. Although females were significantly looser on some joint-looseness tests, they were not looser on the trait indicator.
