Duruöz Hand Index (DHI)
The DHI is a self-reporting scale for the evaluation of hand functions, which was first developed in 1996 for patients with rheumatoid arthritis. It consists of 18 items in 5 domains of kitchen tasks, personal hygiene, dressing, office tasks, and others. Each item is scored between 0-5, to give a total score of 0-90, with higher scores indicating increased hand disability. 13
