Researchers studied the spatial (movement) and temporal (speed) parameters of gait (walk) of 12 CFS patients. They found significant abnormalities in symmetry, which has to do with the movement of one side of the body as compared to the other, as well as other abnormalities. They also found that these abnormalities did not change from the beginning to the end of the exercise period, and so could not have been produced by fatigue. The authors say that this study strengthens the hypothesis that a dysfunction of the central nervous system plays a part in the onset of CFS.
