It was hypothesised that a reduced quadriceps cross-sectional area could be detected by ultrasound in patients with COPD compared with healthy subjects, and that measurements relate to strength and ...

Objectives This study aimed to determine the association between the functionality and the quadriceps femoris muscle (QFM) thickness measured using sonography in patients ... QFM thickness measured ...

Quadriceps femoris (Rectus Femoris-RF, Vastus Intermedius-VIM, Vastus Medialis-VM, Vastus Lateralis-VL) and hamstring (Biceps Femoris-BF, semitendinosus-STT and semimembranosus-SMM) muscles were ...

Objective: To investigate atrophy and weakness of the quadriceps femoris muscle group in patients with PFPS using measures of cross-sectional area and peak extension torque. Methods: A total of 57 ...

OBJECTIVES: We evaluated the validity and reliability of ultrasonography measurement of rectus femoris cross-sectional area compared to computed tomography in patients in pre-dialysis chronic kidney ...
