Swallowing disorders in Parkinson’s disease: impact of lingual pumping

Int J Lang Commun Disord. 2015 Feb 4. doi: 10.1111/1460-6984.12158. [Epub ahead of print]



Lingual pumping (LP) is a repetitive, involuntary, anteroposterior movement of the tongue on the soft palate that is executed prior to transferring the food bolus to the pharynx, but we also observed LP when multiple swallows were taken. LP may be associated with rigidity and bradykinesia in patients with Parkinson’s disease (PD). This phenomenon tends to be more prevalent in dysphagic PD patients, and its impact on swallowing dynamics remains poorly understood.


To evaluate how LP interferes with the oral and pharyngeal phases of the swallowing of foods of different consistencies and volumes.


We used videofluoroscopy to study the swallowing of 69 PD patients performing 10 swallows of barium mixed with foods of different consistencies and volumes.


LP was associated with the unstable intra-oral organization of the bolus, the loss of bolus control, the pharyngeal retention of food and food entering the airway. This abnormal movement was also associated with a shorter oral transit time and was found to be more prevalent with food of thicker consistencies.


LP is associated with swallowing incoordination and with food entering the airway. Preventive measures to minimise the pulmonary or nutritional consequences of this behaviour are necessary.

A new treatment for oropharyngeal dysphagia in Parkinson’s disease was evaluated in the present study.


Prospective randomized controlled trial.


The study describes the effects of surface electrical stimulation (SES) of the neck (submental region) in dysphagic Parkinson patients using different intensities of electrical current. Quasi-random allocation was performed when assigning patients to treatment groups. Three groups consisting of dysphagic patients with idiopathic Parkinson’s disease (N = 90) received daily treatment for 15 days with periods of no treatment during the weekend. All three received traditional logopedic dysphagia treatment. In addition, two groups received SES, either motor-level or sensory-level stimulation. A standardized measurement protocol, including fiber optic endoscopic evaluation of swallowing (FEES) and videofluoroscopy of swallowing (VFS), was performed before and after therapy. A team of experienced raters was blinded to the treatment group and to the moment of measurement. Intrarater and interrater reliability were calculated.


Using proportional odds models (POMs), some of the visuoperceptual ordinal outcome variables showed significant improvement in all groups following treatment. Following 15 days of SES of the submental region, few significant effects were found, suggesting a therapy effect of traditional logopedic dysphagia treatment without any additional influence of SES.


On the grounds of this study, it is concluded that further research is needed on the exact mechanism of SES and its effects on the neural pathways involved in swallowing.
