Modified Scoring of the QuickDASH Can Achieve Previously-unattained Interval-level Measurement in Dupuytren Disease and Carpal Tunnel Syndrome.

Background: Rasch measurement theory can be used to identify scales within questionnaires and to map responses to more precise continuous scales. The aim of this article was to use RMT to refine the scoring of the QuickDASH in patients with Dupuytren disease and carpal tunnel syndrome (CTS).

Methods: Data were collected between 2013 and 2019 from a single center in the UK.

Improving the structural validity of the QuickDASH questionnaire: Exploratory factor analysis and structural equation modelling in 1798 patients with carpal tunnel syndrome.

Study Design: Retrospective cohort.

Background: The QuickDASH is a commonly used questionnaire for the assessment of carpal tunnel patients, although it is unclear whether the questionnaire has suitable structural validity PURPOSE: This study aimed to evaluate the structural validity of the QuickDASH patient-reported outcome measure (PROM), when used in CTS, through exploratory factor analysis (EFA) and structural equation modelling (SEM).

Methods: Between 2013 and 2019, we recorded preoperative QuickDASH scores of 1916 patients undergoing carpal tunnel decompressions at a single unit.

QuickDASH questionnaire items behave as 2 distinct subscales rather than one scale in Dupuytren's disease.

Study Design: Retrospective cohort BACKGROUND: Exploratory Factor Analysis (EFA) and structural equation modelling (SEM) assess relationships between questionnaire items and the constructs ("factors") measured by a questionnaire. The QuickDASH has not been subjected to these analyses in Dupuytren's disease.

Purpose: To undertake EFA and SEM to identify the factors measured by the QuickDASH in patients with Dupuytren's disease.

Hand-arm vibration and outcomes of surgery for Dupuytren's contracture.

Background: Dupuytren's contracture was recently designated a prescribed occupational disease when it occurs in patients with previous hand-arm vibration (HAV) exposure.

Aims: The aims of this study were to describe the impact of self-reported HAV exposure on upper limb function and satisfaction following surgery for Dupuytren's contracture.

Methods: Paired pre- and postoperative Quick version of Disabilities of the Arm, Shoulder and Hand (QuickDASH) and patient satisfaction questionnaires were prospectively collected from all patients undergoing surgery for Dupuytren's contracture over a 6-year period.

Extensor indicis transfer improves function in patients after rupture of the extensor pollicis longus tendon.

The primary aim was to determine the improvement in patient-reported functional outcomes (PROMs) following extensor indicis proprius (EIP) transfer for a closed rupture of the extensor pollicis longus (EPL) tendon. Secondary aims were to analyze the impact of this procedure on health-related quality of life (HRQoL) and satisfaction. Preoperative and one-year postoperative PROMs were collected prospectively at a single institution over a two-year period (2014-2016).

A comprehensive analysis of medium-term outcomes of open first dorsal compartment release for de Quervain's syndrome.

The primary aim of this study is to describe medium-term functional outcomes following first dorsal compartment decompression using a longitudinal incision in patients with de Quervain's syndrome. The secondary aims are to describe the improvement in health-related quality of life and patient satisfaction, and to determine the cost-effectiveness of this procedure. Pre- and postoperative QuickDASH, EQ-5D-5 L, and satisfaction scores were collected prospectively over five years.
