Dysphagia and dysphonia among persons with post-polio syndrome - a challenge in neurorehabilitation.

OBJECTIVE: To study the occurrence of dysphagia and dysphonia in persons with post-polio syndrome admitted into the centre for neurological rehabilitation in Finland.

MATERIALS AND METHODS: Fifty-one persons with post-polio syndrome who were rehabilitated at Käpylä Rehabilitation Centre, Helsinki, Finland, in 2003-2004 were interviewed on problems with swallowing and voice production. Pulmonary function testing and grip strength measurement were performed. A clinical assessment of oral motor and laryngeal functions was carried out for those who reported daily problems with voice production or swallowing.

RESULTS: Fifteen persons (29.4%) reported daily problems with swallowing or voice production. In the clinical assessment, the most commonly observed deficits in swallowing included decreased pharyngeal transit (n = 13) and the food catching in the throat (n = 4). The disturbance of co-ordination of breathing and voice production was seen in 12 persons. There were no significant differences in any of the potential predictors between the groups.

CONCLUSIONS: Professionals need to be aware of the routine evaluation of dysphagia and dysphonia in patients with post-polio syndrome.
