Abstract
Objectives
To critically appraise, compare, and summarize the quality of the measurement properties
of the Dartfish software across various populations and motion tasks.
Data Sources
Systematic electronic searches were performed in the PsychInfo, Embase, [email protected],
CINAHL, and Google Scholar databases from January 1999 to January 2020.
Study Selection
Prospective measurement studies published in English peer-reviewed journals that reported
on at least 1 psychometric property (reliability, validity, measurement error) using
Dartfish were included. An independent reviewer performed searches and identified
studies.
Data Extraction
We followed the COnsensus-based Standards for the selection of health Measurement
INstruments 2018 guideline for abstracting and assessing data quality. Independent
extraction was performed by 2 individual authors. The extracted data involved the
author, year, study population, setting, sample size, and measurement properties,
as well as information on camera positions, analyzed movement variables, and the corresponding
strategy for addressing perspective error.
Data Synthesis
In total, 23 studies were included in this review. Studies were pooled to examine
inter-rater reliability estimates for different tasks: single-leg squat angle (2 studies,
115 participants; intra-class correlation coefficient [ICC], 0.94; 95% confidence
interval [CI], 0.62-0.99), single-leg vertical drop jump angle (2 studies, 94 participants;
ICC, 0.92; 95% CI, 0.20-0.99), and vertical drop jump angle (2 studies, 100 participants;
ICC, 0.88; 95% CI, 0.83-0.92). Concurrent validity (2-dimensional Dartfish vs 3-dimensional
Vicon) was established using the push and release task, single leg stance, and single
leg stance with acutely induced dizziness in 45 healthy Parkinson patients. A correlation
of 0.59 to 0.98 was reported. For tracking angles across various movements, a measurement
error of approximately 10° retest variation was reported in 3 studies.
Conclusion
Dartfish is a reliable software for assessing a variety of tasks across multiple contexts
of assessments. Evidence suggests that the estimates of motion obtained with Dartfish
are valid for single plane movements.
