The Motor Function Measure (MFM) is a global quantitative scale created to measure the functional motor abilities of a person affected by a neuromuscular disease.
It allows classifying the patients of severity in each of the three dimensions of motor function (D1: standing position and transfers, D2: axial and proximal motor function, D3: distal motor function).
It contains 32 or 20 items, each marked from 0 to 3. The total score and the sub-scores are expressed as a percentage of the maximum possible score.
