Effect of vestibular-ocular stimulations on the postural tonic system in patients with the disharmonic syndrome

Author: Doctor Felice Picariello


A 63-year-old woman with postural disharmonic syndrome. He reports postural imbalances and instability during normal daily activities, low back pain, neck pain, and fibromyalgia syndrome. He performed neurological and vestibular specialist examinations which gave negative results for the pathology; physiatric examination diagnosed with fibromyalgia for which he is under medical treatment. The neuro-postural assessment resulted in functional disharmonic syndrome.

The patient was given postural assessment tests with baiobit for the analysis of the balance especially of postural oscillations and tests on the trunk for the evaluation of rotations and lateralizations. The latter were repeated and compared after oculomotor stimulations, the vestibular-ocular reflex (VOR), and the optokinetic reflex (OKR).



Ocular convergences, exercises on the Maddox cross, angular and rectilinear accelerations impressed on the head, sliding of the image on the retina due to the movement of the head and surrounding scenes, combination of VOR with OKR.


The stimulations had an immediate action on postural tone, instantly correcting the dystonias of the postural tonic system (STP); showed an objective improvement in postural balance both on the anterolateral and mid-lateral angles of oscillation and on the speed of oscillation. The LFS equilibrium index went from 0.25 to 0.97.

The immediate correction of the postural tone asymmetry also characterized a marked improvement in the rotations of the trunk and its lateralization, even slightly affecting the pain threshold as evidenced by the VAS scales attached to the graphs.


The case in question is not in itself a treatment report but specifically a complex model of analysis of the vestibular-ocular role on the postural tonic system and the symmetries of muscle tone. Faced with patients of this kind, in the absence of a differential diagnosis related to the clinical picture, it is good to seek, through modern acquisitions and knowledge of functional rehabilitative neurology, in the complex neuro-postural organization the origin of dysfunctional conditions often responsible for nondifferential but highly disabling for the patient’s daily life.
