About Tendinopathy

The group of soft tissue problems often referred to as tendinopathies has always presented a clinical challenge for practitioners of physical medicine because they are often slow to heal, easy to aggravate, and can be very resistant to treatment interventions. This group includes;

  • Tennis/golfers elbow
  • Plantarfasciitis
  • Achilles tendonitis
  • Patellar tendonitis
  • Shin Splints
  • Bursitis
  • ITB Syndrome
  • Rotator cuff tendonitis
  • Hamstring tendonitis
  • Chronic focal soft tissue pain

Chronic tendinopathies, those that have been there for a long time, can be especially challenging. Pain can be severe, and this often causes serious limitation in activities of daily living, work capacity and in sport and leisure activities. Problems with over-consumption of analgesics and non-steroidal anti-inflammatories are common in patients with chronic tendinopathies.

Steroid injection, although often producing a short term positive result, has been shown by meta analysis to have little long term benefit and may inhibit full recovery compared to placebo. (1,2,3)

I use Swiss Dolorclast Radial Shockwave Therapy (RSWT) combined with a range of other interventions in the treatment of these chronic tendinopathies and related disorders. Other interventions include manual treatment of muscles, tendons and connective tissue, acupuncture, low level laser therapy, joint mobilisation, taping and bracing, as well as exercise to strengthen and rehabilitate dysfunctional muscle.

What is Radial Shockwave Therapy?

Radial Shockwave Therapy is an evidence based treatment that has been shown in numerous published studies, including randomized controlled trials, to be a safe and effective treatment for tendinopathies and related soft tissue problems. (4-28)

The technology behind Radial Shock Wave Therapy was developed by the Swiss company EMS. This is the same company that developed Swiss Lithoclast technology, using shock waves and ultrasound for destruction and removal of kidney stones, a process known as lithotripsy.
RSWT treatment of tendinopathy and associated soft tissue disorders is widely used in Europe and North America.

Radial shockwaves are high energy acoustic waves transmitted from a probe held against the painful site. The acoustic shock waves pass through the skin and spread outwards into the underlying tissues. This is believed to induce increased blood flow, activate mesenchymal stem cells and increase metabolic activity around the site of pain, thus activating or accelerating the healing process. RSWT has been shown to effectively reduce pain associated with tendinopathy. It is suggested that this pain reduction effect is a result of over-stimulation of C nerve fibres, these are associated with pain sensation. This over-stimulation at first stimulates, then reduces the production of substance P. Substance P is a neuropeptide associated with pain and inflammation that is found in the brain and spinal cord.

I use EMS Swiss Dolorclast RSWT device. There are a number of less expensive shockwave therapy devices available however the EMS is the only one with numerous published studies showing safety and efficacy.

RSWT Treatment

After examination, painful sites are identified. Shockwaves are applied via a hand piece or applicator held firmly against the skin. The initial phase of treatment may cause some deep pain however this indicates correct targeting of the problem area. This is usually followed by numbness or heaviness in the area and the latter phase of the treatment feels less painful. The treatment sessions are around 10 minutes duration during which the patient may receive up to 2000 pulses. Many patients get pain relief just days after the first treatment. The usual protocol is to deliver 3 to 5 treatments a week apart, depending on the nature of the problem and patient response.

After RSWT Treatment

Some soreness may be felt, which may intensify on the night of the treatment. Simple analgesia and icing may be required to control this pain. There may also be some minor bruising in the treatment area. As far as possible, the patient should refrain from aggravating activities over the treatment period.

SIDE EFFECTS:

Transient post- treatment pain as above.
Local bruising – uncommon and usually minor.
Tendon rupture has not been reported following Radial Shockwave Therapy, unlike cortisone injection and surgery.

CONTRAINDICATIONS:

  • Pregnancy (no side effects have been determined, but safety has not been established)
  • Bleeding and blood coagulation disorders and prescription of anticoagulant medication
  • Skin wound or acute inflammation with effusion in treatment area
  • Tumour in treatment area

RESULTS:

There is no single treatment that is guaranteed to work for everybody. This is especially so in the case of chronic tendinopathies. RSWT has however been shown by high-level evidence to be an effective treatment for a large proportion of patients with tendinopathies. *

Each patient is monitored for their response to treatment and changes to the treatment program are made on a case by case basis. As mentioned above I will often use acupuncture, low level laser therapy (LLLT), manual soft tissue treatment and taping or bracing where indicated to augment RSWT treatment of tendinopathy. Management of tendinopathies almost always incorporates a program of targeted stretching and/or strengthening exercise.

*All but three of the publications 4-28 below demonstrate level 1 evidence of efficacy and safety.
16, 17 and 22 below reached level 3 evidence.
