Supplemental: Congenital Muscular Dystrophy (CMD)
Exploratory: Mitochondrial Disease (Mito)
Short Description of Instrument
The Motor Function Measure (MFM) is a generic scale which provides a measurement of the effects of muscle weakness in neuromuscular diseases (NMD). Assessments are based on posture and movements of the whole body.
This tool makes it possible to follow the evolution of the patients, and to anticipate certain events such as the loss of ability to walk. The MFM can be used to evaluate the effectiveness of therapeutic measures.
Strengths/Weaknesses: Measures patient important functions, excellent reliability and validity, sensitive to change, large age range, possible in ambulatory and non-ambulatory children, measures arm/leg and gross/fine motor function.
Time consuming, ceiling effect in more able patients, not determined whether it measures the acitivites in daily life patients with mitochondrial disease are most limited in (items were included based on experience in patients with neuromuscular disease), dependent on cooperation of the patient
Psychometric Properties: Internal consistency 0.99. Inter- and intrarater reliability 0.96-0.99 in neuromuscular disorders. Correlation with physicians and physiotherapists' severity score 0.88 and 0.91. High correlation between MFM and Brooke, Vignos, WeeFIM in neuromuscular disorders. Predictive for loss of ambulation in patients with DMD.
This instrument has been specifically applied in Duchenne muscular dystrophy, Spinal muscular atrophy, and congential myopathy.
Validated in populations:
• Duchenne muscular dystrophy,
• Becker's muscular dystrophy (BMD),
• Facio-scapulo-humeral dystrophy (FSHD)
• Limb girdle muscular dystrophy (LGMD)
• Myotonic dystrophy (DM)
• Spinal muscular atrophy (SMA)
• Congenital myopathy (CM) and congenital muscular dystrophy (CMD)
• Hereditary neuropathy (HN)
