Play some soft soothing music around her. If she believes in any traditional or other aspect of the Divine it will be helpful to recite a mantra when near her or simply chanting Om while holding her hand.
The fits would of course need to be shown to a physician to find out any underlying cause and administer specific treatment. See if anything triggers these neck movements such as particular light or television near her.
