High-definition Surface Electromyography Markers for the Diagnosis and Monitoring of Sarcopenia

High definition surface electromyography, allowing the recording of muscle activation signals sensitive to the intensity of the contraction and indirectly to the muscle strength as well as to the muscular fatigability, but also capable of measuring the modifications of the recruitment modalities of the motor units. This recording will be made on the rectus femoris during knee extension, either in the lying position or during chair rises, depending on the patient's functional state
