Hi Annette, I did find what I found several years ago about being unable to perform these simple tasks... The interference is a result of the proximity of the two areas of the motor cortex for the same (right or left) hand and foot. When using one from the left and the other from the right this interference does not occur because the two involved areas are relatively far apart - actually in the opposite hemisphere.
