Comparative Effects of Two Conservative Treatments in Teres Major in Handball Athletes With Shoulder Pain

Study Overview
=================
Brief Summary
-----------------
The aim of the study is to investigate the effects of the dry needling technique and diacutaneous fibrolysis technique in teres major muscles on pain, range of motion, strength extensibility and muscular properties of the soft tissues of the shoulder in athletes with shoulder pain.
