Tests and diagnosis

By Mayo Clinic Staff

While the physical examination alone can often confirm a diagnosis of cervical dystonia, it's important to determine if there are underlying conditions causing your signs and symptoms. Tests may include:

  • Blood or urine tests. These may reveal the presence of toxins.
  • Magnetic resonance imaging (MRI). This type of imaging test may be used to identify and visualize tumors or evidence of stroke.
  • Electromyography (EMG). This test measures the electrical activity of muscles. EMG helps evaluate and diagnose muscle and nerve disorders and can help confirm whether you have cervical dystonia or another condition.
