Sensory findings after stimulation of the thoracolumbar fascia with hypertonic saline suggest its contribution to low back pain
Muscle and fascia have been thought to have a poor role as sources of Low back pain. Evidence exists of a relationship between changes in muscle and fascia and LBP. Fascia is innervated by nociceptive free nerve ending and the lumbar dorsal horn neurons receive nociceptive input from the fascia. Connective tissue seems to be in general more sensitive than muscle.
The aim of this study is to investigate the contribution of Thoracolumbar fascia, the erector spine muscle and the sub-cutis to Low back pain. An injection of hypertonic saline into the thoracolumbar fascia has been hypothesized to cause the most intense pain, the largest radiation and the most sensitization to pressure.
