Effects of the Pressure and Traction Technique on the Plantar Footprint and Balance Against a Placebo Laser: A Randomized Single Blind Trial
Effects of the Pressure and Traction Technique on the Plantar Footprint and Balance Against a Placebo Laser: A Randomized Single Blind Trial
The aim of this clinical trial is to check the effects of manual pressure and traction technique on balance and plantar footprint variables comparing with Laser placebo.
Forty healthy subjects wil be recruited for a simple blind study. Participants will be from 1 to 40 years old, not obese. Participants will be randomized into two groups. Experimental group performed a bilateral plantar fascia manual pressure and traction technique. Control group performed a laser placebo. The time duration (5 minutes), position, and therapist were the same for both treatments. The investigators will measure stabilometry variables and static footprint. The footprint variables will be divided in bilateral rear foot, bilateral midfoot, bilateral fore foot.
Measures. 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).
