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

Study Overview
=================
Brief Summary
-----------------
448kilohertz capacitive resistive monopolar radiofrequency is a novel technique in physiotherapy and its usefulness and clinical relevance is still to be investigated at both clinical practice and also in performance. Current studies show promising results in different musculoskeletal disorders, however there no studies in the assessment of quality soft tissue in sporty population after the used of this technique.

Detailed Description
-----------------
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from Baseline in supraspinatus tendon measured by quantified elastography imaging at 3 months | The elastography is obtained when the anatomic image on grayscale ultrasound overlaps parametric color image that expresses the rate of deformity of the tissues, soft tissues tend to develop greater deformity and tissue deformity have lower rigidity. | Time Frame: time (t) 1(prior to treatment), t2 (immediately after the treatment), t3 (3 months later)] |
