Table 3: Change in Signs and Symptoms Pre and Post Training: Study I. The participants reported mild signs and symptoms with minimal change before and after training except for tremor where there was a moderate reduction in both groups and a moderate reduction of arm and leg pain after training on the AlterGR. Difference scores: 0= no problems or no signs and symptoms; 10 = severe signs and symptoms. Negative change is improvement.
