Abdominal cluster
A significant difference was found between the abdominal dimensions of the prodromes and the attacks. However, the means of the prodrome indices were twice lower than the means of the attacks.
Extremities cluster
Significant differences were found between dimensions of the extremities during the prodromes and the attacks. Here again the means of the prodromes were significantly lower than the means of the attacks in this cluster. Similarly, the mean values of the attacks were about twice of the attacks. The means of the degree of functionality and limitations during the attacks in this cluster were higher than in other body clusters.
