  1. The results of the two-way repeated measures ANOVAs showed no significant (p >0.05) mean difference between the anthropometric measures taken directly on the subject’s upper limbs and those taken from photographs. There were no significant two-way interactions for repeated measures ANOVAs performed for hand x fitting procedures. There was a significant main effect for hand (affected versus non-affected), with no significant main effect for fitting procedures (direct versus photographs).
