Group data of the untrained hand pre-MVF and post-MVF and of the trained hand during learning phase (T1–T10) in the ball-rotation task.

MVFNDH	33.50 ± 2.75	17.63 ± 3.41	21.19 ± 3.89	25.00 ± 3.65	26.88 ± 4.02	25.56 ± 3.51	27.56 ± 3.14	31.13 ± 3.50	32.88 ± 3.17	33.88 ± 3.62	34.69 ± 2.87	39.69 ± 2.75

Behavioral data for the trained and untrained hand. Performance of the untrained hand before and after MVF-training (trials 1–10). Performing the ball-rotation task with MVF during learning phase (trials 1–10) resulted in significant performance gains of the trained hand in both groups while there was no difference in the learning rate between groups. For details, see text. Data are presented as mean ± standard error (SE) of the mean.
