Piano trainer kinematic analyses. a. Daily averages during Virtual Piano training for finger fractionation defined as the difference between the angle of the MCP joint of the cued finger and of the most flexed non-cued finger. Higher scores indicate better performance. Averages for 10 subjects are shown (two subjects who used the CyberGrasp haptic device during virtual piano training are not included in this analysis). 2b. Daily averages for all 12 subjects in the time to press each key during piano training. 2c.Daily averages of number of correct keys pressed divided by total keys pressed for all 12 subjects. Error bars = Standard Error of the Mean.
