In 1992 Yahia et al published a paper on the sensory innervation of the human thoracolumbar fascia (TLF). In 7 tissue samples, harvested from 7 subjects, they looked for afferent nerve fibers and their sensory endings.

The used procedure showed the presence of free nerve endings, Ruffini’s, and Pacini corpsules (both mechanoreceptors). Their conclusion, the TLF is well innervated. And, the presence of mechanoreceptors point toward a proprioceptive role of the TLF over the lumbar spine.

Theory to Practice
Yahia’s findings suggest that it might not be sufficient to address TLF related injuries only from a mechanical point of view. The presence of mechanoreceptors implies the necessity of a neurological or segmental approach as well.
