Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Patient satisfaction, the primary outcome, is measured using the validated Dutch version of the Quebec User Evaluation of Satisfaction with Assistive Technology (D-QUEST). Since no literature is published yet about the minimally clinically important difference for the D- QUEST, we defined a value for ourselves. A difference in score on the D-QUEST of more than 10%, this means 0.5 point difference on the 5-point outcome score, is considered to be the margin of clinical significance in this study. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcomes includes pain, measured by a 10-cm visual analogue scale (VAS), and hand function, measured in terms of grip and pinch strength. In addition, hand function and symptoms are assessed using the Dutch version of the QuickDASH. Compliance is quantified by the wearing time per day in hours, reported using a self-reported diary of each patient. At the end of the two treatment periods, patient preference for one of the two braces is asked. | — |
