Examination of the erector spinae muscle. Qualitative and quantitative measurements of the shear wave velocities using virtual touch tissue imaging quantification (Acuson S3000, Siemens) of the erector spinae muscle (shear wave speeds ranging from 0.5 m/s – 6.5 m/s: blue = low shear wave velocities, green = moderate shear wave velocities, red = high shear wave velocities) (Ulm University Hospital, 2013)
