Muscle Cramps and Spasms: Diagnostic Tests

Obligatory medical device diagnostics

  • Electromyography (EMG; measurement of electrical muscle activity).
  • Electroneurography (ENG; method of electrodiagnostics in neurology to determine the functional state of a peripheral nerve).
  • Doppler sonography (ultrasound examination that can dynamically visualize fluid flows (especially blood flow)) – to examine the arterial supply to the legs
  • Computed tomography of the skull (cranial CT, cranial CT or cCT) and spine – in the presence of spasticity.

Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics and mandatory medical device diagnostics – for differential diagnostic clarification.

  • Magnetic resonance imaging of the skull (cranial MRI, cranial MRI or cMRI) and spine – in the presence of spasticity.
  • Sensory/motor evoked potentials (potential differences in the encephalogram (EEG; recording of the electrical activity of the brain), which are triggered by stimulation of a sensory organ or peripheral nerve) – in the presence of spasticity.
