Results of a two-year pilot study aiming at evaluate feasibility, reliability, and validity of various outcome measures, particularly the MFM-32, in 33 subjects with CMD COL6 and LAMA2.
The MFM-32 showed strong inter-rater (0.92) and internal consistency (0.96) reliabilities. Concurrent validity for the MFM-32 was supported by large correlations (range 0.623–0.936) with the following: FVC, NSAA, HFMS, timed functional tests, ACTIVLIM, and QUEST.
The MFM is reliable and valid in the two specific subtypes of CMD evaluated, COL6 and LAMA2.
