Camptocormia and dropped head syndrome as a clinic picture of myotonic myopathy.

Dropped head syndrome is primarily based on weakness localized at neck extensors. It may result from motor neuron disease, myasthenia gravis, and chronic inflammatory demyelinating polyneuropathy and also from various neuromuscular diseases including inflammatory, dystrophic and metabolic myopathies. Camptocormia (CC) on the other hand is an unusual condition characterized by progressive weakness of the extensor vertebral muscles and results in involuntary trunk flexion.

Electrophysiological evaluation of pharyngeal phase of swallowing in patients with Parkinson's disease.

We studied the various physiological aspects of oropharyngeal swallowing in Parkinson's disease (PD). Fifty-eight patients with PD were investigated by clinical and electrophysiological methods that measured the oropharyngeal phase of swallowing. All patients except 1 had mild to moderate degree of disability score.
