This technique is defined as a high-frequency, high-energy acoustic wave with a rapid increase in pressure in a very short time and then a gradual decrease in pressure with a small negative pressure phase. The shock waves are directed to the affected areas that are the source of chronic pain.
The influence of the shock waves causes the dissolution of calcium deposits and leads to a better vascularisation, the subsequent effect is pain relief. Shock waves have the following effects:
- Creation of blood vessels in the area of tendons and muscles, improving blood circulation in the area
- Treatment of erectile dysfunction
- Improved cellular healing and bone remodeling
- Improvement of microcirculation and metabolism
- Dissolution of calcifications
- Enhancement of collagen production
- Reduction of tissue tension and improvement of movement
- Analgesic effect
When applying this technique it is necessary to clean the patient’s skin beforehand and to use a special conductive gel, which will help to guide the acoustic waves generated by the shock wave machine. Once the area to be treated is located, the gel is spread over it and the head of the machine is applied in contact with the gel and the skin.
The patient will feel a non-painful sensation similar to a small hammer striking the area rapidly. Both the intensity and frequency can be adjusted so that the technique does not cause pain, only a slight discomfort when the tissue to be treated is very superficial. Shock waves are indicated for any soft tissue injury: tendinopathies, plantar fasciitis, epicondylitis, muscle or ligament injuries.
After a shockwave session, it is normal for the patient to feel the treated area reddened and with slight discomfort, as this technique works with high power and the tissues respond by becoming slightly inflamed. It is therefore advisable to perform specific therapeutic exercises, as they will help to normalise the situation and reduce the discomfort.
