Muscular Morphological Ultrasound Epidemiological Study in Dance Professionals

Study Overview
=================
Brief Summary
-----------------
This research will determine the presence of groin pain in professional dancers, through a specific questionnaire on the hip joint. Two groups will be formed made up of dancers over 18 years of age, men and women; one with groin pain and one without groin pain. All participants will undergo a functional muscle ultrasound study, where the thickness of the abdominal muscles, lumbar multifidus and gluteus medius and minor will be evaluated, and the relationship between ultrasound neuromuscular changes and groin pain will be verified

Detailed Description
-----------------
The objective of the study is to shed light on the to the complexity of the Diagnosis that Groin Pain (GP) encloses, it is proposed to evaluate with Functional Muscular Ultrasonography Rehabilitative Ultrasound Imaging (RUSI), the layer thickness of the gluteal musculature of the hip and the abdominal and lumbar muscles on a sample of professional dancers over 18 years of age with GP to check if there are differences with professional dancers without GP. Expected goals: Identify the presence of GP in professional dancers. To compare the ultrasound characteristics of the neuromuscular system between a sample of dancers with GP and a sample of dancers no GP. Verify the relationship between ultrasound neuromuscular changes with GP.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| RUSI. (REHABILITATIVE ULTRASOUND IMAGING) | Taking measurements of the layer thickness of abdominal, lumbar and gluteal muscle groups will be performed, with Toshiba's Nemio XG equipment using a multifrequency convex probe from 3 to 6 MGz. | Five months | 

Secondary Outcome Measures
