Results of a study aiming to identify the rate of change of clinical outcome measures in children with 2 types of congenital muscular dystrophy (CMD), COL6-related dystrophies (COL6-RDs) and LAMA2-related dystrophies (LAMA2-RDs).
47 patients were assessed during 4 yeras by outcome measures including MFM-32, myometry, goniometry, pulmonary function tests, and quality-of-life measures.
Total MFM-32 scores for COL6-RDs and LAMA2-RDs decreased at a rate of 4.01 and 2.60 points, respectively, each year (p < 0.01).
