The main goal of the study is to provide a valid outcome measure in order to monitor treatment effects in patients with congenital disorders of muscle.
289 patients, aged 5 to 77 years old, were enrolled and the three domains of the MFM were examined using a Rasch analysis.
The original 32-item MFM did not fit the Rasch model expectations enough in neither of its domains. Switching from a four- (0,1,2,3) to a three-category response scale (0,1,2) restored response order in 16 items. Various additional checks suggested the removal of seven items. The resulting 25-item MFM demonstrated a good fit to the Rasch model. Domain 1 was well targeted to the whole severity spectrum whereas Domains 2 and 3 were better targeted to severe cases. The reliability coefficients of the Rasch MFM-25 suggested sufficient ability for each summed score to distinguish between patient groups.
