Superficial Back Line & Yin Yoga
The Superficial Back Line (SBL), within our fascia matrix, is a continuous line of connective tissue that runs in two pieces: the soles of the feet to the heels & back of the knees. From the knees to the back of the legs, along the sides of the spine & back of the neck, all the way to the top of the head, to your brow line.
Fascia is connective tissue, that weaves its way throughout the body, it supports, & separates our bones, organs, muscles, nerves & blood vessels & connects every part of your body with every other part.
Your bones actually float in a sea of soft tissue & are held in position by our muscles & fascia.
Your fascia connects with our nervous system & brain, & this is how we feel pain, through the fascia sensory cells.
It is this interconnectivity of the fascia matrix throughout the body that can cause physical trauma in one part of our body to result in pain and/or tension felt elsewhere.
Fascia can thicken in one area to support a completely different body part & this can further affect the interconnected structures within its tissue web. Creating lines of tension, pressure on blood vessels, and nerves & holding patterns within our muscles, as the body adapts to the stored pain/tension.
This interconnectivity is why the sole of the foot can be a source of pain felt within the leg or lower back, & why massaging the soles of the feet can also increase the flexibility of your hamstrings. It also explains why your lower back may ache or hurt when you spend a lot of time hunched over a desk or computer.
