Correlation of Muscle Ultrasound Measures (2D and 3D) With Biphotonic X-ray Absorptiometry in Oldest Old Patients.

Nantes University Hospital62 enrolled

Overview

The sarcopenia diagnosis is based on the muscle mass and on impaired physical performance. The emerging field of ultrasound assessment of muscle mass in older patients is based on 2d parameters with prediction equations for muscle mass. For the moment, validation of prediction equations in older adults with varying function and health is lacking. The study aims to evaluate correlation of muscle mass between 3D muscle mass measurement and DXA, in order to dispense with the prediction equation.

Older patients who agree to participate to the study will undergo 3D ultrasound muscle mass measurement, 2D panoramic mode muscle mass measurement and biphotonic X-ray absorptiometry assessment. Correlation analysis will be done with the different measurement.
