Multifidus IMF (links)
Bot- en spiergezondheidIntramusculair vetgehalte in de rechter/linker multifidus-spier, een diepe rugspier die belangrijk is voor de stabiliteit van de wervelkolom.
Ook bekend als: multifidus vetinfiltratie, intramusculair vet multifidus
Hogere IMF-waarden wijzen op vetinfiltratie, wat kan samenhangen met verminderde spierfunctie en rugpijn.
Waarom dit belangrijk is
Higher levels of intramuscular fat in deep back muscles (multifidus) indicate deterioration in muscle quality, which can reduce spine stability, increase the risk of injury. Left-right imbalances in fat infiltration may contribute to asymmetric spine support, potentially leading to compensatory movement patterns and increased risk of chronic lower back pain. Fat infiltration often develops from prolonged inactivity, lack of exercise, or previous muscle injuries. Unlike subcutaneous fat you can lose through diet, reducing intramuscular fat requires targeted exercise to rebuild muscle quality.
This is a research-based wellness measurement for tracking muscle health.
Hoe dit samenhangt met andere biomarkers
- Multifidus IMF (intramuscular fat) reflects fatty degeneration of paraspinal stabilizers, associated with chronic low-back pain, segmental instability, and aging.
- Elevated IMF on the left is interpreted alongside the contralateral side (Multifidus IMF (right)) — marked asymmetry can suggest unilateral pathology (radiculopathy, prior surgery, scoliosis).
- High paraspinal IMF with reduced muscle volume signals true sarcopenic infiltration; correlate with MFI thighs and VAT to SAT Ratio for systemic context.
