Histograms and probability distribution curves for (A) reaction time (B) movement time (C) Z-Task Scores (affected arm) and D) Z-Task Scores (less affected arm) for participants with stroke (N = 112) who completed the Visually Guided Reaching (VGR) task. Black traces are theoretical probability distribution curves for the healthy control subjects (mean/median = 0 and standard deviation = 1). Red curves and histograms represent data collected at the initial time point after stroke (Stroke Initial: ~0.5 months post-stroke). Blue curves and histograms represent the data collected at the final time point (Stroke Final: ~6 months post-stroke). Distribution curves calculated using a probability density estimate using a normal kernel function.
