Results
Static postural control, dynamic stability, or visual dependency during single-leg stance did not change following 30 minutes of transcranial static magnetic stimulation (tSMS) applied over the visual cortex.
These findings suggest that a single tSMS session,when administered in isolation, may not influence sensorimotor control.
