Problems treated with PRONATOS are injuries to the feet, knees, and hips. A foot with a trampled foot arch affects the step not to spring back and develop force in action. It is an essential function for not least athletes to be the difference between succeeding or not in their sport.

It is not uncommon to have one-sided pronation that affects the running step that slowly wears on the body with injuries. Look at the wear on the shoe’s sole. Is it more on the outside of one shoe? Also, look inside the shoe, is it worn inside the heel cap and worn inside above the big toe? The foot does not work as it should.

The loss of power affects the whole body’s biomechanics, which will sooner or later cause injuries 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, Compartment syndrome, Peroneus syndrome, health problems, and various forms of knee pain, often challenging to diagnose.

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

Many surgeons say that the other toe is too long and therefore you get problems, and they want to shorten it. It’s is not possible because you have always had the same length on your toe and have not had issues before.


Constant discomfort from the trampled foot arch is also hip discomfort with Trochanteritis in the hip, and pelvic pain with skew, compensated up in the back.

With increasing age, you often get a trampled foot arch due to overexertion or that you have been lying in bed for a long time. The calf muscles get stiff, which later leads to not lifting 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 with an inward rotation of the heel 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 low balance and strength. You usually wake up with pain the first steps in the morning. It 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 treatment with PRONATOS because what has irritated the foot structures has been corrected. If the healing does not continue, you must examine which structures are still in pain. If pain consists, there may be other inflammatory processes such as bursitis, nerve entrapment (Morton’s neuroma), inflamed tendon sheaths in the foot/ankle (Tendosynovitis). Or the muscles have not been able to regain their function to be able to work normally yet. In these cases, exercises need to stimulate the muscles to start functioning normally again

Trying to correct the errors 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.

It feels better with the soles because the weak muscles that do not work are supported, and the pressure below changes against the sole.

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


A trampled foot arch can cause these pain conditions:
Pain around the hip, Sciatica, Trochanteritis, Scoliosis, leg length differences, groin pain, rupture of the posterior 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, Hammertoe, Morton’s neuroma.

With StretchPower, we perform a treatment called PRONATOS, a new form of therapy that corrects feet. The treatment will regain foot function, which has become incorrect due to overload.

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 come up, you do not get up the foot’s arch in the step, i.e., it collapses. At the same time, the big toe joint destroys because the toe does not come up, the joint compresses for each step, and osteoarthritis develops. 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 problems with running. Here is an article that explains the importance of the arch at running.

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

Since the start of treatment with PRONATOS, ALL patients with Functional Hallux Limitus have regained their maximum mobility. 100% of more than 2000 patients! It always happens after the first treatment! They have not only recovered part of their mobility in a relaxed state but the entire mobility, then you can start walking your standard step again without compensating away the big toe, which leads to compensatory problems.

What happens with our feet?

With age, our arches sink, 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 train, but it can also collapse due to overload.

A short overload can cause the big toe not to come up under load and cause Functional Hallux Limitus, which then worsens to the next step, Hallux Rigidus and then Hallux Valgus. It may be enough to do a heavy lift for the foot to be stressed and the foot’s arch 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 weakness.

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 room to support the foot properly. The foot turns outwards, and the arch of the foot collapses. The big toe moves slowly towards the next toe, and you have got Hallux Valgus

How are we walking?

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

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

The compensations travel upwards and give us problems with the knees, hips, back, and neck. With a stiff big toe, we have to rotate on 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 getting straight over it. We walk on the inside of the toe (medial side).  This way of walking pushes the toe outwards with the risk of Hallux Valgus, and 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.

Turning out the foot puts increased pressure on the foot’s arch 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 reduces.

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

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

The gait of children.

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. This compensation causes the lower leg to twist and get stuck in an inwardly turned position in children. This rotation is put in split at night if it does not return to the straight position. Unfortunately, completely unnecessary suffering for the child as it easily could be treated in time.

Children often compensate for their gait, where they walk over an inwardly rotated foot and load the outside of the foot incorrectly. They also compensate by turning the foot outwards. These conditions are treatable and give a quick result.


  • Mortons Neurom comes from the fact that you can not take the step over the big toe and overload the foot’s outer part.
  • Plantar fasciitis / Health spur comes from the fact that the big toe does not come up and thus not the arch of the foot either. It pulls abnormally in the plantar fascia for each step you take.
  • Hallux Valgus/ Hallux Rigidus due to the big toe not coming up when walking. It starts with Functional  Hallux Limitus, which we effectively can treat. If it is allowed to continue, it will be a more complicated condition to treat with Hallux Valgus, where the toe begins to pull outwards towards the other toe, or Hallux Rigidus, where the big toe base joint starts to stress and stiffen. But we can still get rid of the root cause, and the condition improves.
  • Gubbvad comes from the big toe not coming up, and you stress the calf unevenly when you run. It can also be the big toe muscle (Flexor Digitorum Longus) damaged by the toe, not bending.
  • Achilles tendinopathy is because the calf (the Gastrocnemius/Soleus) muscles pull differently in the heel tendon. There is an imbalance inside the tendon that attaches to the heel bone. The tendon rotates in with the two muscle attachments, making it difficult to equalize the stress inside the tendon from the two muscles. With StretchPower, you immediately affect the imbalance and feel how the pain subsides during the treatment.
  • Nightly cramps, swollen calves comes from the fact that the muscles cannot relax due to the fault loads.
  • Knee and hip problems come from the fact that you have to turn the foot in the step and that the foot’s arch does not come up, which gives an outward rotation of the foot and inward rocking of the knee. The hip joint must rotate in each step, which wears out the joint prematurely.
  • Back problems come from the fact that the arches collapse and give different lengths of legs and twists as compensations upwards to the pelvis and back.
  • Tibialis Posterior Tendinitis and Peroneus tendinitis, inflammation of the tendon sheaths around the ankles, comes from Hallux Limitus (stiff big toe). When the big toes lift to the arch falls off, the Tibialis Posterior muscle but the tendon is slowly but surely overloaded and in the worst-case damaged.


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

The trampled arch makes the leg shorter, with the pelvis lying at an angle with the lower side. Since the pelvis is the back’s base, it tilts, and you get 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 cast insoles in the shoes, do not use them after Pronatos treatment. The shape and function of the foot changes after the treatment, which means that the soles that once made after a diseased foot should not be used.

The foot’s most crucial function is that the big toe can extend/come up in the push-off phase. This feature lifts the longitudinal arch and gives foot stability. It’s the most common issue that patients come up with that is related to their discomfort.

Below is a film of a patient who has been treated with Functional Hallux Limitus, and we test how his insert affected his foot after the treatment.

We can see that the pressure that the insert makes on the medial arch stops the toe’s ability to function normally. Instead of supporting the foot, it removes the foot’s ability to become stable and prevents toe dorsiflexion and the windlass mechanism.
