The Michigan Hand Outcomes Questionnaire domains are based on a scale of 0 to 100. For all domains except Pain, a higher score indicates better performance. For the Pain domain, a lower score indicates less pain.

The effect size is defined as (mean2 - mean1)/(SD of difference in means). An effect size of 0.2 is small, 0.5 is medium, and 0.8 is large.
