Effectiveness of EE With Vibration Versus Cryotherapy in Rectus Abdomini Muscle Thickness and Inter-recti Distance

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determinate de efectiveness of eccentric exercise combined with vibration or cryotherapy in achilles tendinopathy and its effects on the anterior rectus abdominis muscle. The investigators hypothesis is the combined eccentric exercise with vibration get better results than cryotherapy with eccentric exercise in rectus abdominis muscle parameters.
