Abstract

A cohort of 119 patients with carpal tunnel syndrome completed the questionnaire of the Dutch version of the DASH score pre-operatively and one year postoperatively. The mean DASH score decreased from 38.2 to 22.0. There was a significant correlation with the Boston carpal tunnel outcome score (r=0.78). With an effect size of 0.87 and a standardized mean response of 0.69, the Dutch version of the DASH is highly responsive for the evaluation of the outcome of surgery for carpal tunnel syndrome.
