J Neurol Sci. 2017 Dec 15;383:180-187. doi: 10.1016/j.jns.2017.11.015. Epub 2017 Nov 15.


PURPOSE: Lee Silverman Voice Treatment (LSVT LOUD®) is an effective therapy for phonation in Parkinson’s Disease (PD) but little is known about any additional spread of effects to swallowing and cough function. This pilot study examined the effect of LSVT LOUD on pharyngeal swallowing parameters and reflexive cough strength.

METHODS: Twenty participants (14 men, 6 women; mean 68years, SD3.5) with PD referred for LSVT LOUD with complaints of voice deterioration were recruited. Mean duration of PD was 6yrs., SD 3. Self-reported Eating Assessment Tool-10 scores ranging from 0 to 25 (normal<3). Prior to LSVT LOUD, 1-week post- and 6-months post-treatment, participants undertook a videofluoroscopic study of swallowing and aerodynamic measures of involuntary cough.

RESULTS: All participants completed the LSVT LOUD programme; 3 participants were lost to follow-up at 6-months. All participants made significant gains in average sound pressure level (dB SPL). Aspiration was not observed. Pharyngeal residue (p<0.05) and pharyngeal area at rest reduced (p<0.01) while maximal opening of pharyngoesophageal segment (PES) (p<0.05) and PES opening duration (p<0.05) significantly increased. There was a significant improvement in involuntary cough peak expiratory flow rate and peak expiratory flow rise time. All changes were maintained at 6-months.

CONCLUSION: LSVT LOUD demonstrates additional spread effects on pharyngoesophageal deglutitive function and involuntary cough effectiveness in people with mild PD referred with voice complaints. Consequently, LSVT LOUD has potential to provide additional benefits for swallowing safety and efficiency in this patient group.

[Purpose] The purpose of this study was to investigate the effect of jaw opening exercise (JOE) on aspiration in patients with dysphagia after stroke. [Subjects and Methods] Three subjects were recruited. Isometric and isotonic JOE were performed using a rubber ball, 5 days a week for 4 weeks. Aspiration was evaluated using the penetration-a spiration scale (PAS) based on a videofluoroscopic swallowing study. [Results] All subjects showed a score reduction of at least 1 point and a maximum reduction of 2 points in the PAS in the liquid type. [Conclusion] This study confirmed that JOE can be used to reduce aspiration in patients with dysphagia after stroke.

OBJETIVO: Verificar o efeito do sabor azedo e da temperatura fria no tempo de trânsito oral da deglutição.

MÉTODOS: Participaram deste estudo 52 indivíduos (28 do gênero masculino e 24 do gênero feminino) após acidente vascular encefálico isquêmico, com lesão à direita ou à esquerda e disfagia orofaríngea de grau leve a moderado, com idades variando de 50 a 80 anos (mediana=66 anos). Foi realizada a videofluoroscopia da deglutição para a análise dos tempos de deglutição. Cada indivíduo foi avaliado durante a deglutição de bolo na consistência pastosa, oferecido em colher com 5 ml, com quatro estímulos diferentes (natural, frio, azedo e azedo-frio). Após o exame foram realizadas as medidas de tempo de trânsito oral utilizando software específico. Foram mensurados o tempo de trânsito oral (a partir do início do movimento do bolo alimentar na boca) e o tempo de trânsito oral total (a partir do momento em que o bolo é colocado na boca).
RESULTADOS: A associação entre o estímulo azedo e a temperatura fria provocou mudanças significavas no tempo de trânsito oral total e no tempo de trânsito oral, com redução nestes tempos.
CONCLUSÃO: O sabor azedo e a temperatura fria associados apresentaram redução do tempo de trânsito oral em pacientes pós acidente vascular encefálico.

This study investigated the effect of a combined method incorporating the Mendelsohn maneuver and effortful swallowing on aspiration in patients with dysphagia after stroke.

Subjects and Methods:

Three patients with dysphagia were recruited. All patients were treated with a combined method consisting of the Mendelsohn maneuver and effortful swallowing. The intervention period was total 20 sessions. Evaluation was based on videofluoroscopic swallowing study and the degree of aspiration was assessed using penetration-aspiration scale.


Before and after intervention, all participants showed a decrease in aspiration with liquid type and semisolid type food.


This study confirms that the combined method of the Mendelsohn maneuver and effortful swallowing has a positive effect on aspiration in patients with dysphagia after stroke.

Dysphagia. 2017 Nov 28. doi: 10.1007/s00455-017-9867-2. [Epub ahead of print]



The frequency of spontaneous swallowing is useful for screening of dysphagia in acute stroke. Low levels of substance P (SP) in saliva attenuate the swallowing reflex. The aim of this study was to determine the relationship between the frequency of spontaneous swallowing and salivary SP levels. In 40 subjects, saliva was collected within 72 h after stroke onset and salivary SP levels were measured using ELISA kit at a later date. The frequency of spontaneous swallowing was measured over 1 h using a microphone placed on the neck. Pneumonia was diagnosed by the presence of pyrexia and at least two respiratory problems of four categories (sputum, cough or breathing pattern, breath sound, and gas change). The presence of detectable levels of SP in the saliva was confirmed in 17 patients (high SP group), whereas the level was below the detection limit of the ELISA kit in 23 patients (low SP group). The frequency of spontaneous swallowing was significantly lower in low SP group (16.1 ± 11.6 per hour) than in the high SP group (30.4 ± 20.4, p = 0.016). As the result of multiple regression analysis, salivary SP levels were correlated with frequency of spontaneous swallowing independently of age, NIHSS, and GCS. The incidence of pneumonia was significantly higher in the low than high SP group (p < 0.001). In conclusion, the frequency of spontaneous swallowing was decreased in acute stroke patients with low salivary SP levels. Salivary SP levels can be potentially a useful biomarker of risk of stroke-associated pneumonia in the acute stage.

OBJECTIVES: To investigate whether disclosed symptoms (coughing, choking and throat clearing) can be used as early predictors of swallowing disorders in non-hospitalized elderly population. In addition, to determine the presence of early findings of swallowing disorders through fiber optic endoscopic evaluation of swallowing (FEES).
MATERIALS AND METHODS: One hundred subjects older than 60 years were recruited from local community social meetings for seniors, they fulfilled inclusion criteria, and were given an oral interview and underwent FEES, with findings classified as: (1) saliva stasis; (2) pharyngeal residue; (3) penetration; (4) aspiration; (5) laryngeal sensitivity.
RESULTS: Twenty-one percent of subjects declared previous choking, 10% coughing, and 7% throat clearing, 39% had pharyngeal residue; 6% saliva stasis; 9% penetration; 2% aspiration; and 92% laryngeal sensitivity present. Thirty-three percent showed pharyngeal residue without saliva stasis, while only 6% showed positivity for both (p = 0.003).
CONCLUSIONS: Our data suggest that health care professionals should be aware that among an apparently healthy population, some subjects may have swallowing disorders without clinical complaints and that a nasolaryngoscopy exam may not be enough to predict dysphagia. We suggest that FEES should be performed to look for surrogate of dysphagia such as pharyngeal residue, laryngeal penetration, and aspiration.

Sensory input can alter swallowing control in both the cortex and brainstem. Electrical stimulation of superior laryngeal nerve afferents increases reflexive swallowing in animals, with different frequencies optimally effective across species. Here we determined 1) if neck vibration overlying the larynx affected the fundamental frequency of the voice demonstrating penetration of vibration into the laryngeal tissues, and 2) if vibration, in comparison with sham, increased spontaneous swallowing and enhanced cortical hemodynamic responses to swallows in the swallowing network. A device with two motors, one over each thyroid lamina, delivered intermittent 10-s epochs of vibration. We recorded swallows and event-related changes in blood oxygenation level to swallows over the motor and sensory swallowing cortexes bilaterally using functional near infrared spectroscopy. Ten healthy participants completed eight 20-min conditions in counterbalanced order with either epochs of continuous vibration at 30, 70, 110, 150, and 70 + 110 Hz combined, 4-Hz pulsed vibration at 70 + 110 Hz, or two sham conditions without stimulation. Stimulation epochs were separated by interstimulus intervals varying between 30 and 45 s in duration. Vibration significantly reduced the fundamental frequency of the voice compared with no stimulation demonstrating that vibration penetrated laryngeal tissues. Vibration at 70 and at 150 Hz increased spontaneous swallowing compared with sham. Hemodynamic responses to swallows in the motor cortex were enhanced during conditions containing stimulation compared with sham. As vibratory stimulation on the neck increased spontaneous swallowing and enhanced cortical activation for swallows in healthy participants, it may be useful for enhancing swallowing in patients with dysphagia.NEW & NOTEWORTHY Vibratory stimulation at 70 and 150 Hz on the neck overlying the larynx increased the frequency of spontaneous swallowing. Simultaneously vibration also enhanced hemodynamic responses in the motor cortex to swallows when recorded with functional near-infrared spectroscopy (fNIRS). As vibrotactile stimulation on the neck enhanced cortical activation for swallowing in healthy participants, it may be useful for enhancing swallowing in patients with dysphagia.
