Surface electromyography (SEMG) had been and is still widely used in kinesiology and fatigue studies. Its use in routine clinical neurophysiology remains limited. Patients are requiring non-invasive EMG, which could also benefit to physicians and health care system looking for tools to evaluate muscle function in neuromuscular diseases as well as for therapeutic trials.
This is the aim of our clinical studies. We apply SEMG envelope signal analysis acquired from maximal voluntary contractions, and the related compound muscle action potential (CMAP). These unspecific parameters cannot be used for neuromuscular diseases diagnosis, objective under study by many research teams. In nerve lesions follow-up studies, our SEMG procedure is related to motor clinical progression. We are currently evaluating it in chronic neuromuscular diseases. The respective contribution in neuromuscular disorders of the different neurophysiology techniques has still to be confirmed, and compared to force measurement by manual or quantitative testing, dynamometry, other suggested techniques (spectroscopy, imaging) as well as functional scales.
