* Indicates a significant difference at the .05 level.
D = Dominant hand test scores. ND = Non-Dominant hand test scores. Pre = Pre-test scores. Post = Post-test scores. PrePost = difference in scores from pre- to post-test. Peg = Pegboard task. Grip = Regression slope on the grip-force task scores. Cont = Continuous test variables. Error = mean normalised error between the line and the produced myosignals. ErrorSD = standard deviation of the error. Discrete = Discrete test variables, calculated as the regression slopes over the three velocities.
