|Construct validity indicated by binary clinical subgroups at 24 months|
|Clinically meaningful subgrouping||Subscale||Scores|
|Work status||Not working because of ulnar neuropathy (n = 9)||Working or able to work at previous job (n = 34)|
|Ability to do activities||Limited (n = 25)||Not limited (n-27)|
|Sensibility||Abnormal (> 5 mm) (n-14)||Normal (n = 28)|
All subscale scores and the total score were significantly different between subgroups for both work status and activity status. For sensory subgroups only the sensory/motor (SM) symptoms scale was different between subgroups. All p-values were significant at p < 0.01.
