Clinical Applications and Measurement Properties of the Digitized Archimedes Spiral Drawing Test: A Scoping Review.

ABSTRACT:

Background

The digitized Archimedes spiral drawing test (DAST) provides an objective approach for assessing tremor in Parkinson's disease (PD) and essential tremor (ET). Despite its growing adoption in patient care settings and clinical research, the measurement properties of the digitized spiral drawing test beyond tremor are underexplored. Additionally, methodological variability limits its clinical standardization and broader clinical application.

Objective

This scoping review evaluates various applications of the digitized spiral drawing test as a clinical outcome measurement instrument in adult populations, emphasizing its reliability, validity, and responsiveness.

Method

This scoping review examined literature published in MEDLINE, Embase, CINAHL, PsycINFO, Scop
