The Impact Of Fascia Thickness on Chronic Low Back Pain

To investigate the thickness of the fascia tissue, the subjects will undergo an ultrasound examination using a clinical ultrasound system (S9, SonoScape Corporation, made in China) with a linear 5-14 MHz array of L14-5/38. The transducer with a cross-section of 6.24 cm2 will be aimed at points 2 cm lateral to the midline of the L2 and L3 vertebrae on both sides of the spine.
