Effects of Manual Lymphatic Drainage in the Neck in Healthy Subjects. Experimental Randomized Crossover Study

Study Overview
=================
Brief Summary
-----------------
Drainage manoeuvres described in different Manual Lymphatic Drainage methods, suggest modificactions in vital signs, by changes at nervous system, that would involve modifications to heart rate, breathing rate, blood pressure, cardiac vascular level (arteries and lymphatics). In addition this hypothetical relaxing effect could be beneficial for other types of pathologies associated with the presence of stress, cardiac problems, respiratory pathology, muscle tension, muscle trigger points, etc. With this study investigators compare different manoeuvres in the neck area to observe the results in the participants regarding the basal state.

Detailed Description
-----------------
Differentes drainage manoeuvres suggest changes at nervous system (sympathetic and parasympathetic nervous system) and other vital constants
