Kinematic pharyngeal transit times in myopathy: evaluation for dysphagia.

Measurement of kinematic pharyngeal transit times, a new videofluoroscopy technique, provides useful quantitative data to supplement the qualitative data previously available from videofluoroscopy swallowing studies. Kinematic pharyngeal transit times have not previously been reported for subjects with myopathy. This study demonstrates the use of quantitative kinematic pharyngeal transit times for dysphagia evaluation in 15 patients with myopathy. The successful treatment of dysphagia by cricopharyngeal myotomy is reported in two patients with limb-girdle syndrome.
