Stabilometry and Plantar Pressures Changes After Progressive Pressure Release in Flexor Digitoum Brevis in Latent Trigger Points

Study Overview
=================
Brief Summary
-----------------
The aim of this clinical trial is to check the effects of progressive pressure release in the Flexor digitorum Brevis

Detailed Description
-----------------
Eighteen subjects with bilatereal lantent myofascial trigger points wil be recruited for a pre- test post-test study. Participants will be from 18 to 40 years old, not obese. Participants will be measured before and after bilateral dry needling in Flexor digitorum Brevis. The investigators will measure stabilometry variables and static footprint. The footprint variables will be divided in bilateral rear foot, bilateral midfoot, bilateral fore foot. Stabilometry will be measured by displacement of the center of pressures in X and Y with eyes open and closed , center of pressure (COP) with eyes open and closed, COP area with eyes open and closed, COP antero-posterior (a-p) and medio-lateral (m-lat) directions with eyes open and closed, and COP speed. Two trials will be recorded for each condition and the order of the conditions will be randomized across subjects, eyes open and eyes closed. Foot plantar pressure and surface area of two static footprints will be measured during bipedal standing. Static plantar pressure will be evaluated by means of maximum pressure, medium pressure and surface area of each aspect of the foot (rearfoot, midfoot, and fore foot).
