Reliability and Criterion Validity of Physio Master Application for the Measurement of Cervical Range of Motion in Healthy Individuals.
Article in Cureus, 2024. 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
objectiveRecent advances in smartphone applications for measuring range of motion have led to the development of the physio master application by Trinus Laboratory, Navi Mumbai. This app, equipped with a magnetometer and accelerometer, accurately measures the angle between starting and ending device positions. This study aimed to assess the inter-rater and intra-rater reliability, as well as the criterion validity, of the physio master application in measuring cervical range of motion in healthy individuals.
methodThis study included 90 healthy individuals. The two therapists measured the cervical range of motion of each participant twice by using the physio master application (for the inter-rater and intra-rater reliability) and once with the digital goniometer (for the estimation of criterion validity). Then the reliability and validity were estimated by using the intraclass correlation coefficient (ICC).
resultThe study found excellent intra-rater reliability for both therapists (ICCs: 0.77-0.96), with extension showing the highest reliability. Inter-rater reliability was also excellent (ICCs: 0.86-0.96), and criterion validity compared to a digital goniometer ranged from (0.79-0.93), with extension again showing the highest validity.
conclusionThe results demonstrated excellent intra-rater and inter-rater reliability, along with outstanding validity when compared to a digital goniometer. These findings indicate that the physio master application is a reliable and valid alternative to traditional goniometers for measuring cervical range of motion, providing a convenient and advanced tool for clinicians and researchers.
