"I have had a very painful left ankle and foot since childhood due to chronic flat feet. After many injuries to the ankle, I developed Posterior Tibial Tendon Disfunction. A painful, disfiguring condition of the ankle and foot. After being treated weekly with Deep Oscillation by my Physiotherapist, Chris Boynes for the last two years, I am pleased to report that I am mostly pain-free and do not need to wear my ankle brace.

As I live abroad for part of the year, I have now purchased a Deep Oscillation Personal Sport Unit, so that I can carry on my treatment when in the United States and for those times when I can’t get in to see Chris Boynes when back home.

PhysioPod have been wonderful with the supply of the unit; advising on the indications that we should use for best results (for myself and my husband) and the different ways we can apply the therapy to each other or as self treatment. They have also provided a letter for customs to accompany the unit that I will take with me as hand luggage. I thank them for all of their advice. A wonderful company to deal with. Thank you so much.

What is Tibialis Posterior Tendon Dysfunction?

(Source: NHS Patient Information)

No alt text provided for this image

The tibialis posterior is a muscle in the lower leg. The tendon from this muscle runs behind the inside bone on the ankle (the medial malleolus), across the instep and attaches to the bottom of the foot. The tibialis posterior is important as it helps to hold the arch of the foot up and stop the foot rolling over. Sometimes the tendon becomes stretched and inflamed. This condition can be called Tibialis Posterior Tendon Dysfunction, Tibialis Posterior Insufficiency or Acquired Adult Flat Foot.

Common causes

  • Flat footedness: Most people who develop the condition already have flat feet. With overuse or continuous weight bearing, a change occurs where the arch begins to flatten more than before, with pain and swelling developing on the inside of the ankle. Inadequate support from footwear may occasionally be a contributing factor.
  • Trauma or injury: Occasionally this condition may be due to fracture, sprain or direct blow to the tendon.
  • Age: The risk of developing Posterior Tibial Tendon Dysfunction increases with age and research has suggested that middle aged women are more commonly affected.
  • Other possible contributing factors: Being overweight and inflammatory arthritis.


DEEP OSCILLATION® is an internationally patented, proven technology based on the effects of creating an electrostatic field in the tissue of the patient. Easy application is from therapist to patient/client via hygienic, vinyl gloved hands; utilizing all normal massage movements or via circular movements over the tissue with a handheld applicator. The handheld applicator also enables self-treatment. Visit the DEEP OSCILLATION® product range. The special structure of DEEP OSCILLATION® allows the creation of biologically effective oscillations in the treated tissue using electrostatic attraction and friction. In contrast to other therapies, these pleasant oscillations have a gentle and deep-acting effect on all tissue components to an 8 cm depth (through skin, connective tissue, subcutaneous fat, muscles, blood and lymph vessels).

DEEP OSCILLATION® is an especially gentle and an unmatched treatment alternative for fresh trauma, postoperative, for acute pain and in the area of open wounds.

Proof was established in representative studies of the following significant effects of DEEP OSCILLATION®:

Encouraging wounds to heal

DEEP OSCILLATION® helps in speeding up and improving wound healing processes. Through the oedema-reducing and anti inflammatory effect, the local metabolic elimination and alimentation is improved in all tissue layers, whereby tissue regeneration and wound closure are encouraged on many levels. This is documented by the significant improvement in planimetric and biochemical parameters of the wound healing.

Pain Reduction

DEEP OSCILLATION® alleviates pain by reallocating and flushing out pain transmitting and mediating substances. It suppresses inflammation and oedema induced pain by restricting pro inflammatory cell movement to the damaged area, by reducing the inflammatory mediator release, and by oedema reduction.


In chronic pain syndromes and post-traumatic conditions reduced mobility often is caused by constricted microcirculation due to increased tone of the muscles encasing capillary vessels. DEEP OSCILLATION® is muscle relaxing, enables optimal metabolism and normalizing of defective nerve function. As a measurable sign range of movement can be obtained or even increased.

Anti Inflammatory

DEEP OSCILLATION® suppresses acute and chronic inflammation by restricting pro-inflammatory cell movement to the damaged area, by reducing the inflammatory mediator release, and by inhibiting water and protein leakage from the blood and lymph vessels.

Oedema and Fibrosis Reduction

On the level of the interstitium, DEEP OSCILLATION® causes a »shuffling« of the basic substance, thus promoting the removal of interstitial fluid as well as content material. Interstitial septa and fissures are kept open by the mechanical activation, which helps interstitial drainage. This significantly reduces both local oedema and aseptic inflammation. Proof was also established of a significant reduction in swellings in the area of the wound, due to the treatment. In chronic conditions the treatment helps to disperse fibrosis and to diminish hardening of the tissue.
