Using the transcranial magnetic stimulation (TMS) of motor cortex we examined changes in the motor evoked potential (MEP) during natural bimanual unloading, during lifting of an equivalent weight by the contralateral arm while the ipsilateral forearm was held stationary (CONTRA) and during practice of unnatural unloading. During natural unloading, MEP amplitude decreased proportionally to the muscle activity. In CONTRA task MEP amplitude decreased, but the muscle activity was not changed.

- The study investigates postural control learning in patients with left and right hemisphere brain lesions following stroke.
- Both patient groups were trained using two tasks on a force platform to assess their ability to control the center of pressure (COP).
- Results showed that while initial control was impaired for all patients, those with left hemisphere lesions reached higher performance levels earlier compared to those with right hemisphere lesions, particularly in the task requiring precise coordination.
