Fig. 3From: Development of an exercise programme for balance abilities in people with multiple sclerosis: a development of concept study using Rasch analysisBond and Fox pathway map for three dimensions of balance in PwMS. The measure (difficulty estimate) of each balance exercise is plotted against its outfit mean-square statistic. The size of points represents the inverse of the standard error (S.E.) of the difficulty estimate. Green areas indicate adequate fit to the Rasch modelBack to article page
