Bilateral Anterior Thigh Thickness: A New Diagnostic Tool for the Identification of Low Muscle Mass?

To develop an ultrasonographic scanning protocol that included an assessment of muscle size [the proposed Bilateral Anterior Thigh Thickness (BATT)] and quality (echogenicity) to support the diagnosis of sarcopenia in a clinical setting. To determine the relationship of BATT and ultrasound echogenicity with physical function parameters of sarcopenia and test the reliability of ultrasound echogenicity measurements.
