Stabilometric and Baropodometric Evaluation After Osteopathic Scaphoid Tug Manipulation

Study Overview
=================
Brief Summary
-----------------
This is a clinical, longitudinal, prospective and randomised study in which the subject will be assessed by stabilometric and baropodometric techniques on two occasions (before being subjected to the scaphoid tug manipulation for the experimental group or placebo technique in the case of the control group).

Official Title
-----------------
Stabilometric and Baropodometric Evaluation of Osteopathic Scaphoid Tug Manipulation

Conditions
-----------------
Manipulation, Osteopathic

Intervention / Treatment
-----------------
* Procedure: Experimental: Osteopathic manipulation TUG for scaphoid bone
* Procedure: Sham group: Sham osteopathic manipulation TUG for scaphoid bone


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Subjects with right scaphoid external rotation dysfunction Exclusion Criteria: Suffering from disorders that alter balance (tension headaches, vertigo, migraines...). Deformities, orthopaedic injuries or sequelae in the limbs or spine that may alter postural statics (valgus-varus, lower limb operations, lower limb dysmetries, scoliosis, etc.). Pathologies or sequelae related to the postural sensors or disorders in the same: Uncorrected visual defects. Vestibular disorders. Uncorrected stomatological disorders. Sensory alterations in the foot sensor (Hypoaesthesia, Morton's neuroma, tarsal canal syndrome, etc.). Cutaneous alterations that influence the foot pick-up (papillomas, plantar warts, ingrown toenails, etc.). Ingestion of medication that alters the perception of stability. Having any contraindication to the scaphoid tug technique. Having carried out intense physical activity immediately prior to the study. Having received osteopathic treatment in the last month.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Experimental: Osteopathic manipulation TUG for scaphoid bone<br> | Procedure: Experimental: Osteopathic manipulation TUG for scaphoid bone<br>* The sequence of execution of the scaphoid TUG technique shall be applied as follows. Patient in the supine position. The inner hand of the intervener makes contact with the pisiform through the hypothenar eminence and ulnar border of the hand over the scaphoid tubercle, the outer hand reinforces the contact. The thumbs are directed to the sole of the patient's foot. The parameters are sought by bringing the sole of the foot into eversion, thus bringing the scaphoid into internal rotation (the direction of correction). In order to reduce the slack, the operator drops his body weight backwards while increasing the internal rotation parameter of the scaphoid. The manipulation is performed by associating a rapid traction movement with an increase of the correction parameter towards the internal rotation of the scaphoid.<br>|
| Sham Comparator: Sham group: Sham osteopathic manipulation TUG for scaphoid bone<br> | Procedure: Sham group: Sham osteopathic manipulation TUG for scaphoid bone<br>* The intervention will be performed in the same way as the intervention group, without actually performing the TUG manipulation on the scaphoid bone, only placing it in tension.<br>|
