title: URAM scale for functional assessment in Dupuytren's disease: a comparative study of its properties.
abstract: OBJECTIVE
  To test the convergent validity and ease of use of the Unité Rhumatologique des Affections de la Main (URAM) scale for patients with Dupuytren's disease.
  
  
  METHODS
  Patients were prospectively included. We compared the convergent validity of the URAM scale, the Cochin Hand Function Scale (CHFS) and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, in terms of their correlation with the Tubiana score and self-assessed disability on a visual analog scale (VAS). Pearson's correlation was used for the convergent validity study. The response time for questionnaire completion was the outcome for ease of implementation.
  
  
  RESULTS
  We included 53 patients with Dupuytren's disease in the convergent validity study and 30 other patients with the disease in the time-response assessment. The URAM scale showed strong convergence with the Tubiana scale (r=0.64) and self-assessed disability on a VAS (r=0.69). Convergence with the Tubiana and self-assessed disability was higher for the URAM scale than the CHFS or DASH questionnaire. The mean [SD] response time was shorter for the URAM scale than the CHFS or DASH questionnaire (42 [20] vs 71 [35] and 103 [59] s, respectively, P<0.0001).
  
  
  CONCLUSIONS
  The results reinforce the psychometric merits of the URAM scale. Furthermore, the response time for assessing disability was shorter with the URAM scale than the CHFS or DASH questionnaire. This evidence supports the high recommendation for the use of the URAM scale in clinical practice and clinical studies to assess disability in Dupuytren's disease.
