Measuring symptoms severity in carpal tunnel syndrome: score agreement and responsiveness of the Atroshi-Lyren 6-item symptoms scale and the Boston symptom severity scale.

ABSTRACT:

Purpose

To assess score agreement between the Atroshi-Lyrén 6-item symptoms scale and the Boston 11-item symptom severity scale and compare their responsiveness in patients with carpal tunnel syndrome before and after carpal tunnel release surgery.

Methods

This prospective cohort study included 3 cohorts that completed the A-L and Boston scales (conventional score 1-5) on the same occasion: a preoperative and short-term postoperative cohort (212 patients), a mid-term postoperative cohort (101 patients), and a long-term postoperative cohort (124 patients).
