Problems treated with PRONATOS are injuries to the feet, knees and hips. A foot that has had a trampled foot arch affects the step so that the foot cannot spring back and develop force in the step. This is an important function for all, not to mention athletes which can be the difference between succeeding or not in their sport.

It is not uncommon to have a one-sided pronation that affects the running step that slowly wears on the body with injuries as a result. Look at the wear on the sole of the shoe, is it more on the outside of one shoe? Also look inside the shoe, is it worn inside the heel cap and/or is it worn inside above the big toe? If so, this indicates that the foot does not function normally.

The loss of power affects the biomechanics of the whole body, this will sooner or later cause damage that must be treated. A trampled foot arch causes pain in the feet and lower legs such as heel spurs, plantar fasciitis, osteomyelitis, running knees, Tibialis posterior syndrome, Comparment syndrome, Peroneus syndrome, achilles tendon injuries, and various forms of knee pain, often difficult to diagnose.

We also treat Hammartå and Hallux Valgus, these problems are compensatory for malfunction. The hammer toe comes from the fact that the big toe does not bend in the walking phase which then leads to the load ending up on the second toe, which then becomes overloaded. Hallux Valgus comes from walking “around” our big toe and pushing it outwards because we pull the heel inwards to avoid walking over it. 

Many surgeons say that the second toe is too long and therefore you get problems, and they want to cut it, to make it shorter. This is of course a false statement because you have always had the same length on your toe, and have not had the same problems before.



Continued pain from the trampled foot arch is also hip pain with Trochanteritis in the hip, and pelvic pain which is then compensated up in the back.

With increasing age, you often get a trampled foot arch, due to an overexertion or that you have been lying in bed for a long time, this gives a stiffness in the calf muscles which later leads to you not being able to lift the foot when walking. In order not to hit the foot in the street during a walk, you turn the foot outwards (obliquely worn heels), this leads to stepping from obliquely over the big toe and developing Hallux Valgus.

When it has gone so far, you often already have more problems than just Hallux Valgus, but you also have pain of various kinds in the foot with poor balance and strength. You often wake up with pain the first steps in the morning, this shows that there is a fault that irritates the structures even at rest, it will not heal before it is corrected.

The morning pain only subsides after a treatment with PRONATOS because what has irritated the structures in the foot has been corrected. If the healing does not continue, you must examine which structures are still in pain, this may be other inflammatory processes such as mucositis (bursitis), nerve entrapment (Morton’s neuroma), tendon sheaths that are inflamed in the foot/ankle (Tendosynovitis) or the muscles have not been able to regain its function to be able to work normally yet. In these cases, exercises are needed to stimulate the muscles to start functioning normally again.

Trying to correct the errors in your feet with insoles means in the worst case that you prevent it from healing on its own. Molded soles keep the foot at the fault you have and are difficult to heal.

That it feels better with the insoles is because the weak muscles that do not function properly are now receiving support, and the pressure below changes against the sole of the foot.

If you are not well or better from your problems with a single treatment, there are probably other causes for the problem than trampled foot arch, or the trampled foot arch is due to other underlying diseases.



These pain conditions can be caused by a trampled foot arch:

Pain around the hip, sciatica, trochanteritis, scoliosis, leg length differences, groin pain, rupture of the hind thigh muscles, tightness in the IT band, “running knee” / “jumping knee”, schlatter knee, knee osteoarthritis, osteomyelitis, heel inflammation, recurrent ankle sprains feet, high / low arches, overpronation, plantar fasciitis, heel spur, hallux valgus, hammer toe, Morton’s neuroma.

With StretchPower we perform a treatment called PRONATOS which is a new form of treatment that corrects feet. This is done by the foot regaining its function which has become incorrect due to overload.

The overload has given rise to conditions such as Functional Hallux Limitus and Equinus.

Functional Hallux Limitus is a condition that means that the big toe does not come up in the walking phase, if the big toe does not rise, the arch of the foot does not rise in the step, i.e. it collapses. At the same time, the big toe joint is destroyed because the toe does not come up, the joint is compressed for each step and osteoarthritis is formed. The restriction of mobility is the first step, then the joint is destroyed and gets stuck in an immobile position, the last step is that the toe is forced outwards towards the second toe and gives a Hallux Valgus.

Functional Hallux Limitus causes running problems. Here is an article that explains the importance of the arch when running.

Equinus is stiffness in the calf muscles that leads to an abnormal load on the front of the foot. If you do not get your foot up when walking, you are forced to turn your foot outwards to not hit your toes on the ground. Then you also walk obliquely with the foot, which incorrectly loads the foot, knees and hips.

Since the start of treatment with PRONATOS, ALL patients with Functional Hallux Limitus have regained their maximum mobility. 100% of about 1500 patients! This always happens after the first treatment! They have not only regained part of their mobility in a relaxed state but the entire mobility, which then let’s them start walking their normal step again without compensating away the big toe, which leads to compensatory problems.


With age, our arches sink down, the foot becomes wider and the shoes begin to feel tight and uncomfortable. Why? Well, it’s a natural development that comes from less exercise and overload. The foot needs to be trained, but it can also collapse due to overload.

Only overload can cause the big toe not to come up under load and give Functional Hallux Limitus which then worsens to the next step which is Rigidus and then Valgus. It may be enough to do a heavy lift for the foot to be overpaid and the arch of the foot to sink a little. Other causes can be that you get a back shot or just pain in the back so that there is a nerve impact down in the leg so that the muscles are weakened.

Tight shoes negatively affect the foot, with the toes not having enough space, the foot begins to collapse because the big toe does not have space to support the foot properly. This leads to the foot being turned outwards and the arch of the foot collapsing, the big toe is slowly moved towards the next toe so that these are crossed and you have got Hallux Valgus.

How do we walk?

Functional Hallux Limitus is a condition that we compensate for when walking.

There are other reasons why we compensate for our steps, such as that we are stiff in the ankles or that we are weak in the muscles of our feet.

The compensations travel upwards and give us problems with our knees, hips, back and neck. With a stiff big toe, we are forced to rotate the foot to get the big toe “out of the way”, then we pull in the heel so that the toe will come out to avoid walking straight over it. Then we walk on the inside of the toe (medial side), or the side that is towards the centerline of the body. This way of walking pushes the toe outwards with the risk of Hallux Valgus, you get calluses on that side of the big toe. This way of walking makes the trouser legs splashed on the inside when we go out in wet weather, because the heel “waves” inwards at the rear position in the step.

Rotating the foot outwards puts increased pressure on the arch of the foot that is not supported by the windlass system, and it stresses conditions such as Plantar Fasciitis and Heel Spurs. This compensation causes the Tibialis Posterior muscle to become tired and the arch support to be further reduced.

Before this compensatory outward twist that comes at the end of the walking cycle, one often walks on the outside of the foot, balancing on the outer edge of the foot. This pressure on this weaker part of the foot gives conditions such as Tailor’s Knot, where the joint of the little toe is stressed and thickened. This also causes a condition called Morton’s Neuroma, in which the nerve between the 3rd and 4th toes becomes irritated with radiation or numbness.

All of these compensations must be worked out by consciously going right. After the treatment, you get points that you should think about, to get away from a long-term compensated way of walking.

Children and their gait.

Functional Hallux Limitus that prevents the movement of the big toe can come at a very early age.

There are examples of babies taking their first steps with a big toe that does not move properly. Then they have to compensate for the step of turning the leg either inwards or outwards. In children, this compensation causes the lower leg to twist and get stuck in an inverted position. This rotation is split at night if it does not return to the straight position. Unfortunately, a completely unnecessary suffering for the child that could easily have been treated in time.

Children are often seen compensating for their gait, where they walk over an inwardly rotated foot and load the outside of the foot incorrectly. You can also compensate by turning the foot outwards. These conditions are treatable and give a quick result on how the child is doing.



  • Morton’s Neuroma comes from the fact that you can not take the step over the big toe and thus overload the outer part of the foot.
  • Plantar fasciitis / heel spur comes from the big toe not rising up and thus not the arch of the foot either, this pulls abnormally in the plantar fascia for each step you take.
  • Hallux Valgus / Hallux Rigidus comes from the big toe not rising up when walking. It starts with Hallux Limitus which we can effectively treat, however if the condition is allowed to continue it will become a more difficult condition to treat called Hallux Valgus, where the toe begins to pull outwards towards the other toe. The next step is Hallux Rigidus where the big toe’s base joint starts to stress and stiffen. But we can still get rid of the root cause and the condition can be improved.
  • “Gubbvad” comes from the big toe not rising up and you stress the calf unevenly when running, it can also be the big toe muscle that is damaged by the toe not bending.
  • Achilles tendinopathy / inflamation of the lungs comes from the fact that the two muscles of the calf (Flounder muscle / biceps) pull differently in the heel tendon. This creates an imbalance inside the tendon that is attaches to the heel bone. The tendon rotates in rotation with the two muscle attachments, which makes it difficult to equalize the stress inside the tendon from the two muscles. With StretchPower you get an immediate effect on the imbalance and you feel how the pain subsides during the treatment.
  • Nocturnal cramps, swollen calves, are due to the muscles not being able to relax due to the fault loads.
  • Knee and hip problems are caused by having to turn the foot in the step and that the arch of the foot does not come up. The outward rotation of the foot creates an inward rocking of the knee which forces hip joint must rotate in each step which then wears out the joint prematurely.
  • Back problems are caused by the arch of the foot collapsing and giving different lengths of legs and twists as compensation upwards to the pelvis and back.
    • Tibialis Posterior Tendonitis and Peroneal tendonitis, inflammations of the tendon sheaths around the ankles, comes from Hallux Limitus (stiff big toe). When the big toe bending upwards to support the foot arch does not function, the Tibialis Posterior muscle and tendon are slowly but surely overloaded and in the worst case damaged over time.


There are countless examples of how a trampled foot arch affects the body in a chain. Simply explained, you can see the impact on the knee and hip by simply rotating your own lower leg inwards, then the knee is displaced towards the middle, which loads the inner ligament in the knee, the rotation up to the hip is affected by it not being in optimal position for the muscles which attach to the femur, these are then weakened.

The trampled arch makes the leg shorter, with the pelvis lying at an angle with the side lower. Since the pelvis is the base of the back, it tilts and you get a scoliosis in the back that continues up to the neck, where the head is balanced obliquely with muscle tension as a result.



If you have insoles in the shoes, do not use them after Pronatosis treatment. The shape and function of the foot changes after the treatment, which means that the soles that were once made after a deficient foot should not be used.

The most important function in the foot is that the big toe can extend/come up in the push-off phase. This feature lifts the foot arch and gives the foot stability. The only thing that lifts the arch is precisely this function. This is also the most common error that patients come with that is related to their pain.

Below is a film of a patient who has been treated for this particular problem and we test how his old insoles affected his foot.

We can see that the pressure that the insert makes on the hollow foot stops the toe’s ability to function normally. Instead of supporting the foot, it removes the foot’s own ability to become stable.
