Electrodiagnostics and Neuromonitoring in Veterinary Medicine

Cadwell is working in tandem with some of the world’s leading physicians, veterinarians and teaching hospitals. We’re leading the charge in neurodiagnostic technology capabilities in EMG, nerve conduction, evoked potentials, ultrasound, and chemodenervation; IONM; and EEG.

Common electrodiagnostic modalities in veterinary medicine

Sierra Summit can help you test:

  • Brainstem Auditory Evoked Response – BAER tests are non-invasive hearing tests used to diagnose congenital or acquired deafness, and may be a requirement for some breeders. Pure-bred feline patients carrying the white (W) pigmented gene are at a higher risk of congenital deafness. See a list of canine breeds with reported congenital deafness here.
  • Compound Muscle Action Potential – CMAP
  • Single Motor Unit Action Potential – SMUP
  • Motor Unit Number Estimation – MUNE
  • Nerve Conduction Study – NCS
  • Repetitive Nerve Stimulation – RNS

Diagnostic ultrasound imaging

Ultrasonography shows structure and vascularity of internal organs and soft tissues, allows targeted needle guidance, and can be used to identify focal and systemic diseases.

  • Detect and diagnose cancer, abdominal or soft tissue disorders, anomalies, and vascular abnormalities
  • Determine the extent of disease spread
  • Evaluate urology and nephrology
  • Determine causes for abdominal pain, intestinal disorders, and masses
  • Visualize the tendons and ligaments of equine patients
  • Help determine if a mass can be safely surgically removed

    Sports medicine and rehabilitation in veterinary medicine

    • To compare results before and after neurologic or orthopedic surgery
    • Electrical stimulation for diagnosing the possible causes of acute and chronic pain

    Common procedures using IONM in veterinary medicine

    • EEG monitoring to determine stable levels of general anesthesia on animals of all sizes
    • Intervertebral disk disease
    • General surgery
    • Brachycephalic airway disease
    • Laryngeal paralysis
    • Collapsing trachea
    • Cleft palate
    • Salivary mucocele
    • Other small animal surgeries

    Common uses of brain monitoring in veterinary medicine

    Electroencephalography (EEG) is a neurological exam used in conjunction with clinical examination to determine the cause of seizure activity and monitor the effectiveness of anti-seizure medications. Cadwell’s new ambulatory EEG Apollo+ solution provides the opportunity to capture EEG measurements from active, moving patients in real time with mobile data capture.

    Quality and scalability make Cadwell equipment the right choice for large and small animal patients


    • The Synchronized Patient Database includes all studies, reports and other associated documentation
