Data and R code for: Multidimensional reliability and validity of the mobile virtual reality subjective visual vertical (MVR-SVV) measurement system in inpatients with stroke

<p dir="ltr">This dataset contains the de-identified participant-level data and the R code supporting a study of the inter-rater reliability, measurement error, and convergent validity of a mobile virtual reality subjective visual vertical (MVR-SVV) measurement system in 40 inpatients assessed in the acute phase after stroke.</p><p dir="ltr">Files: svv_analysis.csv is the de-identified participant-level dataset (n = 40), reporting the mean and standard deviation of the 10 trials of each measurement together with demographic and clinical characteristics.

SVV_figures.R is a base-R script that reproduces Figures 3-6 and the reported reliability, agreement and bootstrap statistics. data_integrity_check.R verifies, for every measurement, that the tilt-corrected value equals the raw angle minus the recorded device tilt. README.md contains the full data dictionary, reproduction instructions and de-identification details.</p><p dir="ltr">To reproduce the figures and statistics, place svv_analysis.csv and SVV_figures.R in the same directory and run source("SVV_figures.R", encoding = "UTF-8") in R. No packages beyond base R are required.
