Dysphagia Grand Rounds 6

One of the major issues with the management of people with dysphagia is the discontent and in many cases, the refusal to adhere to diets composed of thickened fluids. Given that modified diets raise serious clinical management problems with respect to hydration and quality of life; and in the absence of conclusive scientific evidence, numerous facilities have adopted policies allowing patients free access to water. However, this is not a uniform policy with minimal documented evidence to reflect the practice.  

Dysphagia Grand Rounds 6 reviews a randomized-control prospective study that investigates the effects of oral intake of water in people with dysphagia with previously identified aspiration. Read the article below before watching the DGR 6 webinar to maximize your learning experience.

Abstract: 
BACKGROUND
Dysphagia is associated with numerous medical conditions and the major intervention to avoid aspiration in people with dysphagia involves modifying the diet to thickened fluids. This is associated with issues related to patient quality of life and in many cases non-compliance leading to dehydration. Given these concerns and in the absence of conclusive scientific evidence, we designed a study, to further investigate the effects of oral intake of water in people with dysphagia. 

METHODS
We monitored lung related complications, hydration levels and assessed quality of life in two groups of people with dysphagia. The control group was allowed only thickened fluids and patients in the intervention group were allowed access to water for a period of five days. 

RESULTS
Our findings indicate a significantly increased risk in the development lung complications in patients given access to water (6/42; 14.3%) compared to the control group (0/34; no cases). We have further defined patients at highest risk, namely those with degenerative neurologic dysfunction who are immobile or have low mobility. Our results indicate increased total fluid intake in the patients allowed access to water, and the quality of life surveys, albeit from a limited number of patients (24% of patients), suggest the dissatisfaction of patients to diets composed of only thickened fluids. 

CONCLUSIONS
On the basis of these findings we recommend that acute patients, patients with severe neurological dysfunction and immobility should be strongly encouraged to adhere to a thickened fluid or modified solid consistency diet. We recommend that subacute patients with relatively good mobility should have choice after being well-informed of the relative risk.

Dysphagia Grand Rounds 5

May is Stroke Awareness Month. More than 50% of the 665 thousand stroke survivors experience dysphagia acutely, of which approximately 80,000 experience persistent dysphagia at 6 months. Early treatment of dysphagia aims to reduce secondary complications such as dehydration, malnutrition and pneumonia and allows for spontaneous recovery of swallowing function. For those with dysphagia persisting beyond the acute phase, it is crucial to continue treatment that, in addition to reducing secondary complications, targets the physiologic deficits caused by the stroke with the goal of improving swallowing function or compensating for lost function (Vose et al., 2014).

Dysphagia Grand Rounds 5 reviews a recent research study that compares two tongue-pressure resistance training protocols for post-stroke dysphagia. Read the article below before watching the DGR 5 webinar to maximize your learning experience.

Abstract
The objective of this study was to compare the outcomes of two tongue resistance training protocols. One protocol (“Tongue-Pressure Profile Training”) emphasized the pressure-timing patterns that are typically seen in healthy swallows by focusing on gradual pressure release and saliva swallowing tasks. The second protocol (“Tongue-Pressure Strength and Accuracy Training”) emphasized strength and accuracy in tongue-palate pressure generation and did not include swallowing tasks. A prospective, randomized, parallel allocation trial was conducted. Of 26 participants who were screened for eligibility, 14 received up to 24 sessions of treatment. Outcome measures of posterior tongue strength, oral bolus control, penetration-aspiration and vallecular residue were made based on videofluoroscopy analysis by blinded raters. Complete data were available for 11 participants. Significant improvements were seen in tongue strength and post-swallow vallecular residue with thin liquids, regardless of treatment condition. Stage Transition Duration (a measure of the duration of bolus presence in the pharynx prior to swallow initiation, which had been chosen to capture impairments in oral bolus control) showed no significant differences. Similarly, significant improvements were not seen in median scores on the Penetration-Aspiration Scale. This trial suggests that tongue strength can be improved with resistance training for individuals with tongue weakness following stroke. We conclude that improved penetration-aspiration does not necessarily accompany improvements in tongue strength, however tongue-pressure resistance training does appear to be effective for reducing thin liquid vallecular residue.

Mother of Dysphagia

For #BHSM (Better Hearing and Speech Month) and Mother's Day, we are paying homage to an extraordinary woman who has made a profound impact in the field of swallowing disorders
Dr. Jerilyn 'Jeri' Logemann

Dr. Jeri Logemann - Mother Of Dysphagia

Dr. Jeri Logemann was an internationally-renowned clinician, researcher, educator, mentor, and leader in the field of swallowing disorders (dysphagia) and speech-language pathology (SLP). She worked tirelessly to advance our knowledge of normal swallowing as well as treatment for those suffering from swallowing disorders.

Dr. Logemann was the Ralph and Jean Sundin Professor of Communication Sciences and Disorders at Northwestern University and Professor of Otolaryngology and Neurology at Northwestern University Feinberg School of Medicine, where she directed the Voice, Speech, and Language Service and Swallowing Center.  After obtaining her bachelors, masters and doctoral degrees from Northwestern University, she joined the faculty and became one of the most influential leaders in the field of speech-language pathology.  A prolific scholar; she contributed ground-breaking books, journal articles, workshops, conference presentations and seminars on the management of voice disorders, normal swallowing physiology, and the assessment and treatment of speech and swallowing in head and neck cancer patients and those with neurological impairments.  A pioneer in the development of techniques for effective assessment and treatment of speech and swallowing disorders she (with Dr. Hilda Fisher) developed the Fisher-Logemann Test of Articulation Competence. She also developed the modified barium swallow study (MBSS) test, now considered to be the ‘gold standard’ test in the assessment of swallowing disorders.

Regarded as the leading authority in the assessment and treatment of dysphagia, Dr. Logemann's research was continuously funded by the US National Institutes of Health and other agencies for over 30 years. She formed the Clinical Sciences and Disorders Clinical Trials Research Group (CSDRG) in 1995 to assist in the design and conduct of large-scale treatment studies of speech, language, learning, voice, swallowing, hearing and balance disorders. She was an active member of IALP serving as the Chair of the Dysphagia Committee and co-founded the Dysphagia Research Society in 1991; the first trans-disciplinary society of its kind to promote research in the field of swallowing disorders. Dr. Logemann was a Fellow of the American Speech-Language-Hearing Association (ASHA) and the Chicago Medical Society, and a recipient of the ASHA Honors of the Association, that organization’s highest award.  She was elected as the President of ASHA twice, serving from 1994-1997 and 2000-2003.

Dr. Logemann passed away on June 19, 2014 at the age of 72, surrounded by the love and warmth of her family and friends. Today, speech-language pathologists are considered to be the experts in the assessment and treatment of swallowing disorders across the lifespan and across a number of healthcare settings. This would not have been possible without the work done by trailblazing leaders in the field such as Dr. Jeri Logeman. We honor her today as the #MotherOfDysphagia on this Mother’s day, for all the tremendous challenges she overcame to live life to the fullest and ultimately move our profession forward.

Dr. Jerilyn Logemann’s relentless commitment to her work, skilled leadership, indomitable spirit despite relentless physical challenges, and her loyalty and generosity will be forever missed by her patients, students, friends and colleagues.
