Fig. 3From: Accelerometry-enabled measurement of walking performance with a robotic exoskeleton: a pilot studyImprovements across training for individual patients. Each plot displays an individual feature and each color denotes a different patient. Data is averaged over 2 sessions (1 block). Solid lines are the least squares linear fit to the data. The green dotted line and the shaded areas indicate mean ±2 standard deviations across expert subjects. Error bars are ±1 standard deviation from the meanBack to article page
