Figure 4

Mean vertical force level during a standardized writing task. The task required the participants to write the sentence “Die Wellen schlagen hoch” (The waves are surging high). Participants had to continuously write ten sentences without a break. The columns reflect the mean vertical force level that was applied by the participants during the first three (left panel) and last three sentences (right panel) of the task. In 21 patients (grey columns), vertical force level was measured at baseline (week 0), after immobilization (week 4), after four and eight weeks of re-training (week 8 and 12). The black columns give the mean vertical force level of 21 healthy controls. The asterisk indicates a significant decrease in vertical force level relative to baseline in the patient group (p < 0.05). Error bars equal onefold standard error of the mean.
