How We Assess You To Create A Clear Story From Root Cause To Current Symptoms, Based On Anatomy Trains: The True Muscular System.
How the Map Works
By now, you've seen how a healthy back feels light, supported, and free. You've also seen how that design gets quietly interrupted, often decades ago, when the breath is restricted, the pelvis tilts, and the body starts compensating just to stay upright against gravity.
Now comes the moment most people find life-changing.
We don't guess where your pain is coming from. We map it.
When the pelvis drifts even slightly off-centre, through anterior tilt, lateral shift, or rotation, gravity no longer flows evenly through your skeleton. Your body has only one goal: to keep you standing and moving. So it does what it must. It redistributes the load along lines of tension to hold you upright.
Those lines of tension are called Anatomy Trains. Continuous bands of Fascia and muscle that connect distant parts of the body like long, interconnected ropes. When one part of the chain is pulled or restricted, the tension travels through the chain. The body compensates along these trains, and that's exactly where pain eventually shows up.
Two of these trains are central to understanding almost every case of chronic back pain we see at Physology.
The Anatomy Trains Map
Here's a short word from the creator of Anatomy Trains, Tom Myers, the researcher whose work underlies our entire assessment method.
The Superficial Back Line
We see this as a single continuous tissue, and it is the most commonly affected by chronic back pain as a result of the dysfunctional movement caused by the pelvis and Diaphragm issues we've covered so far.
The Superficial Back Line runs from the plantar Fascia under your feet, up through your calves, hamstrings, along the spine to the base of your skull, and over the top of your head to your eyebrows. It is one single connected tissue.
When the pelvis tilts forward, this entire line is placed under uneven tension. The body compensates, and those compensations travel along the line until they find their weakest point. For most people, that weak point, the place where the tension accumulates and the pain eventually appears, is the lower to mid back.
The Moment This Changes Everything
When you look at the Superficial Back Line running as one connected system from foot to skull, something important may click into place. You may have spent years describing what felt like completely separate problems to different doctors. Lower back pain to your GP. Neck pain and headaches to a physiotherapist. Tight calves and Achilles problems to a sports therapist. Restless legs at night that nobody could explain. Perhaps recurring hamstring tightness that never fully resolved no matter how much you stretched.
They listened to each symptom in isolation, because that is how they were trained to see the body. They had no map that connected these experiences into a single pattern.
But when you understand the Superficial Back Line, you can see them all as one conversation. The same line of tension, pulling at different points along its length, expressing itself differently depending on where it finds its weakest link that day.
How the Same Line Creates Different Symptoms
Lower Back Pain
The most common accumulation point. The Superficial Back Line is under uneven tension from a tilted pelvis below and tight suboccipital muscles above. The lower back sits in the middle of that tug, absorbing the load from both directions.
Neck Pain & Headaches
The Superficial Back Line attaches at the base of the skull and over the top of the head. Tension from the lower back travels up and compresses the suboccipital muscles, creating the classic tension headache and persistent neck stiffness driven by the same restriction.
Migraines
The suboccipital region sits directly over the vertebral arteries and the greater occipital nerve. Persistent Fascial compression here can reduce blood flow and irritate the nerve, contributing to migraine patterns that have been treated with every approach except releasing the line creating the compression.
Achilles Pain & Plantar Fasciitis
The line begins at the plantar Fascia and runs up through the Achilles into the calf. Tension higher up pulls the whole chain taut, and the weakest point at the bottom takes the load. This is why Achilles and plantar Fasciitis problems so often fail local treatment, because the driver is higher up.
Restless Legs
Often dismissed or medicated. In our clinical experience it frequently reflects Fascial tension and impaired circulation through the calves and hamstrings, keeping the nervous system activated even when the body is trying to rest.
Tight Hamstrings That Never Improve
Years of stretching with no lasting result is one of the clearest signals the problem is not the hamstring itself but the Fascial line it belongs to. Stretching the muscle without releasing the whole pattern is like trying to loosen a knot by pulling harder on the rope.
This is why treating just the back rarely works. The restriction driving the pain is often somewhere else along the line entirely. And until someone maps the whole system, the symptoms keep returning.
If the Superficial Back Line is the most visible train in back pain, the Deep Front Line is the most overlooked. And it is the one that most practitioners never assess.
The Deep Front Line runs from the underside of the foot through the inner leg, up through the deep hip flexors and psoas, through the front of the spine, behind the sternum, and all the way up through the neck to the base of the skull. It is the body's deepest longitudinal support structure, the inner core of the Fascial web.
The psoas muscle, which is part of this line, attaches directly to the lumbar vertebrae. When the Deep Front Line becomes restricted, the psoas shortens and compresses the lumbar spine from the front. From the outside, this looks like lower back tightness. But treating the back doesn't release the psoas. The restriction is hidden on the inside, pulling the spine forward and loading the lumbar discs asymmetrically with every step you take.
This is one of the most common hidden drivers of chronic lower back pain we find at Physology, and one of the most consistently missed by practitioners who are not trained to look for it.
What you are seeing in that footage is real Fascia, filmed during dissection. That shimmering, fibrous, web-like tissue is what fills the space between every structure in your body. It is not an inert filler. It is a living, fluid-filled, tension-bearing system that connects everything to everything else.
At the site of your back pain, the Fascia looks and feels different from healthy tissue. Where healthy Fascia is hydrated, supple, and slides freely, restricted Fascia becomes dense, dehydrated, and adhered. It loses its ability to glide. Layers that should move independently start to stick together, creating what we feel with our hands as a thickening or gumminess in the tissue.
When Fascia becomes restricted, it starts to compress the structures it surrounds. The muscles within that Fascial envelope cannot fully contract or lengthen. They become shortened, overloaded, and unable to generate force cleanly. This is what creates the chronic tightness and weakness that no amount of stretching or strengthening will fully resolve, because the problem is not in the muscle itself, it is in the casing around it.
Nerves travel through Fascial sheaths. When those sheaths become thickened and restricted, the nerve is placed under constant low-level compression. This produces the aching, burning, or hypersensitive quality that many people with chronic back pain describe, where even light touch or prolonged sitting becomes painful. The nerve is not damaged. It is compressed by the tissue it runs through.
The solution is not to treat the muscle or the nerve in isolation. It is to release the Fascia. When we work into restricted tissue with precision, we restore hydration and mobility to the Fascial layers, decompress the structures beneath, and allow the muscles and nerves to return to normal function. This is what changes the quality of tissue that patients and practitioners can both feel, and it is what produces lasting resolution rather than temporary relief.
Your chronic back pain is not a mystery once you have a clear assessment and treatment system like the Physology Method. The tissue tells the story. We read it and we treat it at source.
Your Type of Back Pain and the Fascial Connection
Back pain is not one thing. The location, character, and pattern of your pain tells us a great deal about which Fascial lines and structures are involved. Below are the most common presentations we see at Physology, and how each connects back to the Fascial system.
Lower Back Pain
The most common presentation. Usually driven by a combination of Superficial Back Line tension from below (tight hamstrings, restricted calves) and Deep Front Line compression from the psoas. The lower back becomes the accumulation point for compensations from both directions. Treating only the lumbar region addresses the symptom but not the drivers.
The QL sits deep in the lower back, connecting the 12th rib to the pelvis. When the pelvis is unlevel due to pelvic tilt or a lateral shift, the QL on one side is chronically overloaded as it works to hold the pelvis level. This creates a deep, one-sided lower back ache that is often described as catching with certain movements. The QL's Fascial envelope connects to the thoracolumbar Fascia, meaning restrictions here transmit tension widely across the back.
The SI joint sits where the sacrum meets the pelvis. When the pelvis is imbalanced, the load through the SI joint becomes asymmetrical. The thoracolumbar Fascia, which attaches directly to the sacrum, transmits tension from the Superficial Back Line directly into the SI joint. This creates inflammation and pain that is often felt as a deep ache on one side of the lower back, frequently misdiagnosed as a disc problem or sciatica. Releasing the Fascial lines that load the SI joint from above and below is what resolves it.
Mid back pain between the shoulder blades is often driven by the Superficial Back Line being pulled taut from below while the Spiral and Lateral Lines create rotational forces through the thoracic spine. Poor rib mechanics, restricted breathing, and long periods of sitting in forward flexion all compress the thoracic Fascia. This area is rarely treated as a Fascial problem, which is why mid back pain tends to respond poorly to conventional approaches.
Sciatica is the experience of the sciatic nerve being irritated, producing pain, tingling, or numbness along its path from the lower back into the leg. The symptoms can be debilitating, a shooting, burning, or electric sensation that travels from the buttock down the back of the thigh and sometimes into the calf and foot.
Conventional medicine defaults to disc herniation as the explanation, and many people spend years being managed around a disc that may not be the actual driver at all. What is frequently missed is a condition called Piriformis Syndrome, and in our clinical experience it is responsible for a measurable proportion of what gets labelled as sciatica.
The piriformis is a deep muscle in the buttock that runs from the sacrum to the top of the femur. The sciatic nerve passes either through or directly underneath it depending on the individual's anatomy. When the pelvis is imbalanced, particularly with a forward tilt or a lateral shift, the piriformis is placed under chronic asymmetrical load. It tightens and shortens. And when it does, it compresses the sciatic nerve directly, not at the disc, but in the buttock itself.
The symptoms are identical to disc-related sciatica. The same pain pattern, the same referral down the leg, the same sensitivity. Which is why one is so frequently mistaken for the other. The distinction matters because the treatment is completely different. Releasing the piriformis and the Fascial restrictions that are driving it through the Deep Front Line and lumbopelvic system resolves the compression at source. We have consistently good results treating sciatica presentation this way, including in patients who have had imaging showing disc changes but whose symptoms have not responded to disc-focused treatment.
If your sciatica came on gradually rather than from a sudden disc event, if it is worse with prolonged sitting, and if it is accompanied by the postural imbalances described on the previous pages, Piriformis Syndrome deserves serious consideration before assuming the disc is the cause.
The Physology Method was built specifically from this global approach. We have a clear map of your body, its back pain symptoms, the root cause, and the journey it has taken to reach its current state. Now all we need to do is reverse that journey by undoing the Fascial and Anatomy Trains restrictions and adhesions, starting at the root cause and working to the site of pain.
This gets you pain free.
Once pain free, we address the imbalanced skeletal system and treat your Fascia to restore balance. This is how we correct the original postural dysfunction, allowing your body to function long-term, pain free, and in balance.
In your consultation, we will show you your specific assessment findings using images and video, so you can see exactly what is happening in your body and understand the precise restriction pattern that has been creating your symptoms. For the first time, your pain will have a complete explanation.
