All cell values are mean (95% CI), and all hand outcomes are specific to injured side (hand or wrist), except the MHQ Work domain, which has one score for both hands. Functional measures are % of the injured hand/wrist compared to the uninjured wrist.
Abbreviation: MHQ=Michigan Hand Outcomes; ADL=activities of daily living.
a
: MHQ Summary and domain scores, except pain, range 0–100, with 100 indicating no hand disability. Pain scores also range 0–100 but 0 indicates no pain;
b
: SF-36 scores range 0–100, with 100 indicating the best quality of life
