Assessing the quadratus femoris muscle by MSK ultrasound
The quadratus femoris muscle is an important muscles that provides stabilisation in the hip joint. The size of the muscle can be measured by the golden standard MRI and MSK ultrasound. MSK ultrasound is less expensive and easily feasible. The anterior and medial muscle groups measured with MSK ultrasound is valid. The quadratus femoris muscle is yet not examined according to the literature. During the measurement there can be include if there’s par example a muscle tear, the therapy can be made patient specific.
The purpose of this study was to compare the validity of measuring the quadratus femoris muscle with the golden standard MRI and MSK ultrasound by professional ballet dancers.
Measuring the quadratus femoris muscle by MSK ultrasound is valid in the axial plane of the cross sectional area. MRI in comparison with MSK ultrasound shows a difference of 9% between the measurements. MSK ultrasound is a great tool to measure the size of the quadratus femoris muscle and the outcome of the measurement can be used in therapy such as evaluation of training, biofeedback, etc.
