  2. bTwo tests (four finger tapping and ten word list learning) were redesigned during the study and only 26 of the 44 participants in the reliability group took the slightly modified battery.
  3. cThe subjects were asked “Do you have computer knowledge, yes or no”.
  4. dSubgroup of the “computer - interface” group. Patients diagnosed with INPH.
