Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Behavioral outcome during balance learning is the error produced by balancing on an unstable balance board (Sensamove, Groessen, NL). The error, in degrees, is computed as the cumulative deviation between the position of the board relative to the horizontal. TMS outcomes include the size of the short-interval intracortical inhibition (SICI), long-interval intracortical inhibition (LICI), and corticospinal excitability measured as the amplitude of the motor evoked potential (MEP). EEG outcomes include the phase slope index, a measure of connectivity in the frequency domain between specific brain areas. | — |
