A scale was developed to measure the severity of stenosing tenosynovitis : the Amsterdam
Severity Scale in Stenosing Tenosynovitis (ASSiST). PURPOSE : To study the interobserver reliability of the ASSiST. METHODS: Patients suffering
from various impairments in hand function were referred to our outpatient hand
clinic. The grading of stenosing tenosynovitis was assessed independently. The
observers were blinded for each other's results. The ASSiST distinguishes between
a nodular and a diffuse form. The severity was graded from grades 0 to 3.
RESULTS: Kappa coefficient for the distinction between the four grades was 0.72
(95% confidence interval [CI] 0.59-0.85) and for the distinction between the
nodular and the diffuse forms 0.16 (95% CI 0.13-0.18). CONCLUSION: The ASSiST can
be used to reliably assess the severity of stenosing tenosynovitis in both
nodular and diffuse forms, but it does not differentiate between these two forms.
LEVEL OF EVIDENCE: Not applicable.
