Effects on Plantar Support After Deep Dry Needling in Posterior Tibial Muscle

This study aims to analyze the changes in plantar support after the technique of deep dry puncture in the posterior tibial. The data will be analyzed by a baropodometer which will record the possible changes in the footprint. The investigator will perform a pre-intervention measurement and 3 post-intervention measurements (immediately after the intervention, at 24 hours and at 72 hours)

The inspector, with gloves, disinfects the area to be treated with 70º alcohol. Once the alcohol is applied, the intervenor locates and takes the myofascial trigger point and places the needle with the guide tube resting on the skin of the patient. The inspector holds the guide tube between the index and middle fingers lightly touch the needle with the index finger of the other hand to insert the needle perpendicularly into the skin, directing it towards the inspector's thumb. Once the needle is inserted subcutaneously, the guide tube is removed. The controller deepens the needle to myofascial trigger point, and makes fast inputs and outputs into it. The rapid exit is made to the subcutaneous cellular tissue, outside the muscle, but not outside the skin. Next, hemostasis is performed in the area. Once this hemostasis is completed, the patient is incorporated and dressed.

The patient lies on the stretcher without the trousers. The interventor, with the guide tube, simulates the technique of puncture in the right twin of the subject. The comptroller cleans the area with 70º alcohol. Once the alcohol is applied, he performs the simulated dry needling technique in a plane with his index and middle fingers with the guide tube. It is important that the subject has his head stuck in the hollow of the head of the stretcher throughout the technique to make a correct masking.

Amount of pressure (Kg/cm2) applied at the tibialis posterior myofascial trigger point site that elicit pain for the patient will be reported
