In this pilot study four subjects were observed to determine the extent of the natural movement of their centers of gravity in relation to arc height during the two-point touch cane technique. The subjects learned and practiced a modified technique using their center of gravity as much as possible. Analysis of the data revealed that each subject was, to some extent, able to incorporate the movement of the center of gravity into the two-point touch technique.
