Inter-trial reliability by number of trials and patient subgroups. a Intraclass correlation coefficients (ICCs) and (b) standard error of measurement (SEM, in degrees) for 2, 4, 6, 8 and 10 trials for patients with contralesional VV bias (n = 48), ipsilesional VV bias (n = 17) and normal VV perception (n = 52). In (a), the dotted line represents ICC ≥0.9 indicating high inter-trial reliability
