High-degree ataxia without failure of the central nervous system, with or without clearly reduced flexibility of the neck in grown horses and foals shows together with medical history in most cases the localization of the cause: the neck.

But what to do when subtle signs of ataxia, for instance dysmetria of hind legs, uncoordinated downhill walking, ambling when going backwards, slightly reduced flexibility of the neck or badly localized lameness show up?

These symptoms could result from changes of the spinal cord and/or the nerves from the neck muscles and thoracic spine.  Besides extensive clinical examinations (including neurological and orthopedic examinations and imaging methods (MRI, myelography, X-Rays, ultrasound), electromyography can be used additionally as a diagnostic method.

At ISME, a clinical study examines, if and how well the results of the quantitative electromyography (qEMG) of the neck muscles of the horse corresponds with imaging and pathological findings.  The reliability of this method is being examined herewith.
