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).

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.
