Dynamic Plantar Pressures Changes After Dry Needling in Flexor Digitorum Brevis Versus Non Emission Laser

Thirty-six subjects randomly distributed between a dry needling intervention group and a control group whose intervention is a non-emission laser. All the subjects will be measured before and after the interventions of each group. The measurements will be made on a pressure platform to record the dynamic footprint variables of the first step of both feet.

• Bilateral dry needling in latent trigger points of the Flexor digitorum Brevis Muscle (Other): Bilateral dry needling in latent trigger points of the Flexor digitorum Brevis Muscle in flatfoot
• Bilateral non emission Laser in latent trigger points of the Flexor digitorum Brevis Muscle (Other): Bilateral non emission Laser in latent trigger points of the Flexor digitorum Brevis Muscle in flatfoot
