Abstract
We report the first case of diffuse abnormal insertional activity with bulbar muscle involvement. Electromyography performed 5 months earlier reported multilevel radiculopathy. A repeat electromyography study revealed short trains of positive waves without fibrillation potentials, diffusely present in all tested muscles. Positive waves were also found in the bulbar innervated muscles; these included the trapezius, frontalis, and the orbicularis oculi. This entity is important to recognize because confusion with neuromuscular syndromes can occur.
