Muscle Health Measurements Using Electrical Impedance Myography

This study is being done to further develop a device, the mScan, to measure muscle health as compared to measurements of muscle health using MRI (magnetic resonance imaging). This device is held against the skin and uses Electrical Impedance Myography (EIM). EIM uses a very small, noninvasive (e.g. no needles), brief (about 6 seconds), and painless electrical current to measure the muscle. The investigators will look at how the mScan predicts the muscle measurements seen on MRI in people with and without muscle disease. The investigators hope that this can be used in the future as a quick, convenient and less time-consuming way than MRI to assess muscle health. This could be used to measure how well treatments for different muscle disorders are working over a period of time.

Natural History Study for Patients With Nemaline Myopathy in Spain

The objective of this natural history study is to comprehensively characterize the disease progression and clinical features of nemaline myopathies. The study aims to establish a well-defined cohort of patients in Spain, enabling long-term follow-up and facilitating recruitment for future clinical trials.

Observational Study to Observe Variations of Gait Parameters in Patients With Neuromuscular Diseases

This study has the general objective of observing walking parameters during a clinical test to objectively estimate fatigue in patients with neuromuscular diseases. Furthermore, the investigators want to evaluate the feasibility of collecting physical activity in daily life conditions during a one-week monitoring period using a wearable sensor.
