• Recall muscle anatomy and use EMG identification of muscles in technically difficult areas, such as the neck, forearm, and face.

• Recognize the electromyographic patterns associated with dystonia.

• Recognize the differences in the currently available botulinum toxins, their different dosing and sided effect profiles, and use in movement disorders.

• Recall the concepts underlying generation of sensory and motor nerve action potentials, motor unit action potentials, and the interference pattern.

• Recall the principles of analysis of motor unit action potentials and interference patterns.

• Identify signals acquired with concentric needle and single-fiber electrodes, recognize artifacts and describe the significance of abnormalities.
