Facioscapulohumeral Muscular Dystrophy

The goal of this study is to investigate the effects of personalized exercise treatment on dynamic balance and physical function in comparison with regular follow-up in adults with rare-neuromuscular disorders: Charcot-Marie-Tooth (CMT), Facioscapulohumeral Muscular Dystrophy (FSHD), and Myotonic Dystrophy Type 1 (DM1). The key objectives are: 1. To investigate if the intervention group experiences improvements in dynamic balance that are superior to the control group 2. To investigate if the intervention group experiences long-term improvements in dynamic balance that are superior to the control group during the follow-up 3. To investigate if improvements in dynamic balance are associated with improvements in physical activity, body composition, estimated motor units, metabolomics, muscle echnogenecity and volume, and other indicators of health and quality of life. This is a national study and will involve 120 individuals with rare-neuromuscular disorders from Norway's four health regions.
