Figure 2. Mean group passive SWE modulus values of thoracolumbar fascia (TLF), erector spinae (ES), multifidus (MF) values at knee flexion angles of 0, 45 and 90°. Error bars indicate standard deviation and circle dots are individual case values (* indicates statistically significant difference compared to the uninjured group; ^ values collapsed across angles and groups are statistically significant greater than ES and MF, p < .05).
