To examine the effects of lingual exercise on swallowing recovery poststroke.
Prospective cohort intervention study, with 4- and 8-week follow-ups.
Dysphagia clinic, tertiary care center.
Ten stroke patients (n=6, acute: < or =3mo poststroke; n=4, chronic: >3mo poststroke), age 51 to 90 years (mean, 69.7y).
Subjects performed an 8-week isometric lingual exercise program by compressing an air-filled bulb between the tongue and the hard palate.
Isometric and swallowing lingual pressures, bolus flow parameters, diet, and a dysphagia-specific quality of life questionnaire were collected at baseline, week 4, and week 8. Three of the 10 subjects underwent magnetic resonance imaging at each time interval to measure lingual volume.
All subjects significantly increased isometric and swallowing pressures. Airway invasion was reduced for liquids. Two subjects increased lingual volume.
The findings indicate that lingual exercise enables acute and chronic dysphagic stroke patients to increase lingual strength with associated improvements in swallowing pressures, airway protection, and lingual volume.

    • "se in cortical excitability after 5 Hz rTMS may result in better tongue movements, but not increasing tongue strength. It may be possible that increasing tongue strength is better achieved by building up of tongue muscles through isometric exercises. It was found that increased tongue strength is associated with increased tongue volume (Robbins et al. 2007). Michou et al. (2014) proposed an alternative treatment method, paired associative stimulation (PAS), in which electrical stimulation is applied to the muscles and TMS is applied to the corresponding cortical representation. Their results showed more significant improvements in penetration-aspiration scores after PAS than after rTMS. T"

    ABSTRACT: There is growing evidence of potential benefits of repetitive transcranial magnetic stimulation (rTMS) in the rehabilitation of dysphagia. However, the site and frequency of stimulation for optimal effects are not clear. The aim of this pilot study is to investigate the short-term effects of high-frequency 5 Hz rTMS applied to the tongue region of the motor cortex on swallowing functions and the quality of life of post-stroke individuals with dysphagia. Two male and two female participants were assigned randomly to active and sham groups. The participants in the active group received 10 sessions of active rTMS for 2 weeks, whereas the sham participants received 10 sessions of sham rTMS for 2 weeks. Each participant received a total of 3000 pulses of 5 Hz active or sham rTMS per day for 10 days. Outcome measures were taken at baseline, 1 week and 1 month post-rTMS. Participants who received active rTMS had improved swallowing functions and swallowing-related quality of life at 1 week and 1 month post-stimulation. The study showed that excitatory rTMS applied over the tongue motor cortex is a feasible approach in individuals with chronic post-stroke dysphagia. Further investigation with larger sample population is warranted to support the benefit of this stimulation protocol. © 2015 Royal College of Speech and Language Therapists.

    • "In order to perform this measurement, the image of the valleculae after the first swallowing of each one of the tested volumes and consistencies is frozen on the computer screen. The marker indicating the end of a swallow was the termination of hyoid motion post first swallow [28,29]. Measurements (height and width), in millimeters, were performed on the actual computer screen using a digital caliper. "

    ABSTRACT: Breathing and swallowing are physiologically linked to ensure effortless gas exchange during oronasal breathing and to prevent aspiration during swallowing. Studies have indicated consistent aspiration in chronic obstructive pulmonary disease, mainly related to delayed swallowing reflex and problems with lingual propulsion and pharyngeal peristalsis as a result of bilateral weakness and incoordination of the related muscles. The purpose of the present study was to evaluate swallowing transit times and valleculae residue characteristics of stable COPD patients who have no swallowing complaints. Our study population included 20 stable patients with COPD and no swallowing complaints and 20 healthy controls. Swallowing was assessed through videofluoroscopic examination and involved the analysis of the following parameters: (1) pharyngeal stages of deglutition; (2) the duration of bolus movement through the oral cavity and pharynx (i.e. transit times); (3) valleculae residue ratio; (4) penetration/aspiration. Participants of the study did not present any signs of penetration-aspiration for any of the tested consistencies. Patients with COPD presented longer pharyngeal transit times during the ingestion of the liquid consistency and during the ingestion of the paste consistency. Regarding the duration of tongue base contact with the posterior pharyngeal wall, COPD patients also presented longer durations for the liquid and paste consistencies. No significant difference was observed for the distribution of individuals among the different valleculae residue severity levels. Our study suggests that stable COPD patients may present physiological adaptations as a protective swallowing maneuver to avoid aspiration/penetration of pharyngeal contents. Moreover, valleculae residue cannot be seen as an isolated factor when trying to explain swallowing alterations in this population.

    • "A similar divergence of scores was found for pressures measured at the posterior palate, with the boundary between groups lying between 303 and 355 mmHg (i.e., 40–47 kPa). It should be noted that in this study the maximum isometric pressure (MIP) scores reported for aspirating seniors were in the range previously reported to be normal for healthy seniors [13, 14, 46, 47]. Based on these previous studies, MIPs below 300 mmHg (i.e., 40 kPa) are typically considered to represent reduced tongue strength. "

    ABSTRACT: Penetration-aspiration is considered the most serious component of oropharyngeal dysphagia. Clinicians regularly evaluate the pathophysiology of swallowing and postulate reasons or mechanisms behind penetration-aspiration. In this article we share the results of a two-stage literature review designed to elucidate the association between abnormalities in physiological measures of swallowing function and the occurrence of penetration-aspiration. In the first stage, a broad scoping review was undertaken using search terms for nine different structures involved in oropharyngeal swallowing. In the second stage, based on the results of the initial search, a more focused systematic review was undertaken which explored the association between aspiration and abnormalities in respiratory, tongue, hyoid, and laryngeal function in swallowing. A total of 37 articles underwent detailed quality review and data extraction in the systematic review. The results support measurement of tongue strength, anatomically normalized measures of hyoid movement, bolus dwell time in the pharynx while the larynx remains open, respiratory rate, and respiratory swallow phasing as parameters relevant to aspiration risk.
