Overcompensation for the force perturbation. A and B: angular error at 100 ms (means ± SE) for each subgroup during abrupt and gradual training. Bin size is 2 trials immediately following set break and 6 trials for the remainder of the block. C: average angular error at 100 ms (means ± SE) during the last 6 trials when the field was at full strength in both abrupt and gradual conditions. Controls showed overcompensation in both conditions. The severe patients did not show significant overcompensation in either condition.
