Measurements of quadriceps function are particularly helpful initially post surgery, however traditional quadriceps strength measures like isokinetic testing are contraindicated during this time period. Inclusion of dynamic musculoskeletal ultrasound imaging in the clinical setting has been beneficial in understanding quadriceps activation specifically rectus femoris (RF) contraction; however, there is a paucity of literature in this area. The purpose of the current study was to describe the cross-sectional area (CSA) of the RF across varying knee flexion angles. Forty-five adult recreational athletes were recruited for the study (21 males, 24 females). All subjects underwent tests of maximal volitional isometric contractions of the knee extensors at 0, 30, 60 and 90 degrees of knee flexion. During the trials, musculoskeletal ultrasound images of the RF at 15 cm from the supe...
