Head posture is influenced by many diseases of nervous system, visual and vestibular systems. We describe new method of non-invasive head position measurement.
Pictures of the head marked on tragus and outer eye canthus are taken simultaneously by two digital cameras aligned by laser beam. Head position is measured with precision of 0,5 degrees in three planes (rotation -yaw, flexion-pitch and inclination-roll).
Mean values of head position (100 healthy controls): retro flexion 21,7 degrees; inclination to the right 0,2 degrees; head rotation to the left 1,7 degrees.
