Hypothesis
Can the QuickDASH be used as a valid and reliable alternative to the full-length DASH questionnaire for assessing upper extremity disorders?
Conclusion
The QuickDASH can be used instead of the DASH with similar precision in upper extremity disorders.
Supporting Evidence
- The QuickDASH scores were consistently higher than the DASH scores across different diagnostic groups.
- The reliability of the QuickDASH was found to be high, with an ICC exceeding 0.90.
- The mean difference between QuickDASH and DASH scores was statistically significant but clinically negligible.
Takeaway
The QuickDASH is a shorter questionnaire that works just as well as the longer DASH for measuring arm problems.
Methodology
The study analyzed QuickDASH responses from 105 patients with upper extremity disorders before and after surgery, comparing scores from the QuickDASH and DASH questionnaires.
Limitations
The study's findings may not apply to all patient groups, and the small number of patients in certain diagnostic categories limits generalizability.
Participant Demographics
Mean age of participants was 52 years, with 57% women and 43% men.
