Assessment of the Fascial System Thickness in Patients With and Without Low Back Pain (PMID: 40870911)
Research Question
Does the thickness of fascial tissues differ between people with and without low back pain (LBP), and could these differences help us better understand pain patterns?
This review explored whether variations in the thickness of the superficial fascia, deep fascia, and subcutaneous tissue could serve as a useful marker for assessing low back pain.
Methods
Researchers conducted a narrative review of published human studies investigating tissue thickness in the lower back region.
The literature search included studies examining:
Superficial fascia
Deep fascia
Thoracolumbar fascia
Subcutaneous tissue
A total of 21 studies published up to February 2024 were included and analyzed.
Researchers compared findings between:
Individuals with low back pain
Individuals without low back pain
Key Findings
The review found that fascial and soft tissue thickness can vary considerably between people and across studies.
Main findings included:
People with low back pain often showed equal or greater thickness in deep fascia and subcutaneous tissues compared with individuals without pain.
Evidence for differences in superficial fascia thickness remains limited and less consistent.
Thickness values varied depending on:
Age
Sex
Body region being measured
Considerable variation existed both within studies and between studies, suggesting fascia may behave differently across individuals and anatomical sites.
Why It Matters for Fascia
This review supports the idea that fascia may play a more active role in low back pain than previously thought.
Changes in tissue thickness could reflect:
Adaptation to loading
Altered movement patterns
Changes in tissue hydration
Remodeling processes associated with persistent pain
The findings also highlight that fascia should not be viewed as identical across the body—its structure may vary depending on the person and location.
Understanding these patterns may eventually support more individualized assessment and treatment approaches for low back pain.
5 Takeaways
Deep fascia and subcutaneous tissues may be thicker in people with low back pain.
Fascial thickness appears to vary from person to person and body region to body region.
Superficial fascia remains less studied and needs more research.
Age and sex may influence normal fascial thickness values.
Measuring fascia could become part of future patient-specific assessment strategies.
