Test-retest reliability of fMRI activity levels in the missing hand ROI. Averaged percent signal change was extracted from each participant's first-level analysis using ROI₃ (defined by control participants' non-dominant hand movement activity). To ensure our ICC values were minimally affected by differences in scanner type, we normalised activity levels by dividing by intact hand movement activity levels extracted from an intact hand ROI. ICC = intraclass correlations; CI = 95% confidence interval.

	ICC-Value	ICC-CI
Phantom/intact hand movement activity	.75	.07 – .93
Lip/intact hand movement activity	−.22	−3.54 – .67
Residual arm/intact hand movement activity	.15	−2.14 – .77
