The aim of this clinical trial is to check the effects of progressive pressure release in the Flexor digitorum Brevis
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).

| Static footprint | Static footprint will measure plantar presures and surface area of rear food, midfoot and fore foot. Subjects were instructed to stand barefoot on the force platform, participants were instructed to remain in a relaxed standing posture with feet shoulder-width apart and positioned at 30º away from the midline. During all the examinations, the upper limbs were placed in a relaxed position along the body. The subjects were instructed to stand as still as possible for 30 s, with their eyes open, while concentrating on a point at eye level 2-m away or with their eyes open. | Through study completion, an average of 3 days |
| Stabilometry variable x displacement open eyes before progressive pressure release | Stabilometry assessment was used and subjects were instructed to stand barefoot on the force platform, participants were instructed to remain in a relaxed standing posture with feet shoulder-width apart and positioned at 30º away from the midline.

| Stabilometry variable y displacement open eyes before progressive pressure release | Stabilometry assessment was used and subjects were instructed to stand barefoot on the force platform, participants were instructed to remain in a relaxed standing posture with feet shoulder-width apart and positioned at 30º away from the midline.

| Stabilometry variable center of pressure area open eyes before progressive pressure release | Stabilometry assessment was used and subjects were instructed to stand barefoot on the force platform, participants were instructed to remain in a relaxed standing posture with feet shoulder-width apart and positioned at 30º away from the midline. Stabilometry variables measure displacement of the center of Pressure (COP) area (in milimeters²) with eyes open. |
