Clinical Applications and Measurement Properties of the Digitized Archimedes Spiral Drawing Test: A Scoping Review.
Article in Movement disorders clinical practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe 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.
objectiveThis 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.
methodThis scoping review examined literature published in MEDLINE, Embase, CINAHL, PsycINFO, Scopus, and Web of Science, including studies on adults (≥18 years) using the DAST, to assess fine motor function.
resultsOf 120 included studies, 84 focused on PD or ET, with emerging applications in other conditions. Digital tablets were the most used administration method (66.6%), but task design, metrics, and analysis varied. Measurement properties were reported in fifty-two studies (43.3%): 15 on reliability, 45 on validity, and 6 on responsiveness. Results demonstrated consistent reliability, strong correlations with gold-standard clinical measures, and sensitivity to interventions.
conclusionsThe digitized spiral drawing test shows strong promise as a reliable and valid tool for assessing fine motor function in clinical and research settings. However, significant variability in devices, drawing tasks, and analysis methods across studies highlights the need for standardized protocols. Future research should focus on harmonizing methods, expanding its application across different conditions, and ensuring its clinical relevance as a measurement instrument.
