Patients data beforePR programView this table:Table 2. Patients data after PR programConclusion: The rectus femoris cross-sectional area measurements with ultrasound may be a candidate for non-invasive method of measuring muscle mass change in PR patients.We wish to present the early results of 3 cases in this pilot study.
