Outcome measures
Primary outcome
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. In addition to the performance on the balance board, the laboratory behavioral outcome is the magnitude of sway on the force platform measured in standing with a narrow stance during TMS and EEG testing. Magnitude of sway is expressed in cm as path length over unit time and the velocity of sway in the anterior-posterior and in the medio- lateral directions.
Secondary outcome
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.
Study objective
The overall hypothesis is that balance-specific exercise training only improves postural control of sway measured in standing and causes retention of the improved sway behavior and that such behavioral improvements correlate with changes in measures of neuronal excitability in the brain.
Study design
acute study: week 1
Chronic study: week 1, week 4 and week 6
Intervention
Balance training on an unstable surface, cycling on an a stationary bicycle ergometer and no-intervention control
