Key Descriptions

  • 18 questions regarding ability to carry out manual tasks. Questions are grouped in five domains: In the kitchen (8), dressing (2), hygiene (2), in the office (2), and other (4)
  • The patient is instructed to answer each question in terms of the level of difficulty they experience completing various tasks without help from another person or assistive device (Sezer, Yavzer, Sivrioglu, Basaran, & Koseoglue, 2006)
  • Individual items are scored on a 6-point Likert scale where 0=without difficulty and 5=impossible. The 18 individual scores are summed to obtain a composite score
  • The total score ranges from 0-90 with higher scores indicating poorer hand functioning

Considerations

  • The DHI has not been studied on patients with significant hand impairments or severe contractures.  Therefore, the DHI may be better suited for patients with mild hand impairments rather than patients with severe hand contractures or severely compromised hand function (Poole, 2005)

  • The DHI has been issued to patients without significant cognitive deficits and therefore, should be considered for patients without cognitive impairments

  • The DHI assesses hand ability and does not take into consideration other symptoms that may impact hand function such as pain or numbness
