Weakness of the neck extensor muscles leading to a ''dropped head phenomen“ is not uncommon in generalized neuromuscular diseases. A similar clinical feature is known from patients with a Parkinsonian syndromes. In the literature, single case reports indicate a possible coincidence of an extrapyramidal syndrome and myopathies. In particular an increased incidence of neck-extensor myopathies with a resulting dropped head syndrome and the occurrence of a „bent-spine“ syndrome in MSA-P were described.
