POTENTIAL ROLE OF THORACOLUMBAR FASCIA IN YOUNGER MIDDLE-AGED PATIENTS WITH CHRONIC LOW BACK PAIN.

Individuals afflicted with chronic LBP exhibited pronounced thickening of the thoracolumbar fascia and attenuation of the lumbar multifidus muscle in comparison to asymptomatic counterparts. Notably, increased thickness of the thoracolumbar fascia corresponded to heightened pain intensity, while reduction in lumbar multifidus muscle thickness was associated with decreased lumbar flexion ability. These findings underscore the importance of incorporating tailored regimens targeting both fascial and muscular components in the rehabilitation of individuals with LBP.
