Fascia thoracolumbalis
The thoracolumbar fascia is not a muscle but a critical connective tissue sheet enveloping the back muscles and transmitting forces between the hindquarters and forelimbs. It originates from the spinous processes of the thoracic and lumbar vertebrae and the iliac crest and inserts on the ribs, transverse processes, and latissimus dorsi and abdominal muscles. Its actions are to transmit forces across the back and stabilize the spine during locomotion. It acts as a tension band for spinal stability. It has sensory innervation from the dorsal rami of spinal nerves.
Origin: Spinous processes of thoracic and lumbar vertebrae; iliac crest
Insertion: Ribs, transverse processes, and latissimus dorsi/abdominal muscles
Action: Transmits forces across the back; stabilizes the spine during locomotion
Innervation: Sensory innervation from dorsal rami of spinal nerves
Relevant in evaluations of back pain and force transmission between the hindquarters and forelimbs. Dysfunction or injury can contribute to reduced spinal stability and performance issues. Diagnosis is clinical.
## Overview Fascial tension and restriction describe tightness and reduced mobility of the connective-tissue layers over the back and trunk. It contributes to widespread stiffness and reduced spinal
Persistent back stiffness or reduced performance should be evaluated. Balanced work and correct saddle fit help maintain function.
## Overview Fascial tension and restriction describe tightness and reduced mobility of the connective-tissue layers over the back and trunk. It contributes to widespread stiffness and reduced spinal motion and often responds to myofascial release and mobilization techniques. It is a care/management finding rather than a primary disease. ## What It Indicates Chronic postural adaptation, compensatory guarding, or residual restriction after injury. ## Diagnosis Palpation of skin and fascial mobility, assessment of spinal range of motion. ## Treatment Myofascial release, stretching, massage, and correction of underlying postural or training issues. ## Recovery and Prognosis Good with consistent manual therapy and appropriate exercise. ## Prevention Regular mobility work and balanced training. Signs include: widespread back stiffness; reduced spinal motion; tight, immobile skin over the back; improvement with myofascial techniques
