Ultrasound Supraspinatus Tendon Assessment After 448kilohertz Radiofrequency Stimulation in a Sporty Population.

Shoulder pain is is one of the most common musculoskeletal disorders, presenting a high prevalence in primary care centers and sport populations. Many factors have been proposed as the cause of pain, however there are no studies analysing possibilities of preventing shoulder injuries by using a radiofrequency stimulus.

The use of 448kilohertz capacitive resistive monopolar radiofrequency as the focus of the treatment looking for improve the quality of the tissue is still to be explored.

The hypothesis of the present project is that focus treatments on 448kilohertz capacitive resistive monopolar radiofrequency on the shoulder will produce better outcomes in terms of ultrasound assessment measured by quantified elastography, and this will decreased the possibilities of get injured.

The stimulus will be carried out on the shoulder region (suprascapular, axillar, subscapular, long thoracic or pectoralis nerves) and the thoracic region. All interventions will be developed by the same examiner, who is a physiotherapist with 6 years of clinical experience.
