Behavioral Interventions Targeting Base of Tongue to Posterior Pharyngeal Wall Approximation: A Scoping Review.

Pharyngeal pressure generated by approximation of the base of tongue to the posterior pharyngeal wall (BOT-PPW approximation) is critical for efficient pharyngeal bolus passage and is a frequent goal of dysphagia management. This scoping review evaluated behavioral interventions available to improve BOT-PPW approximation. We searched MEDLINE, CINAHL, Ovid Emcare, Web of Science, SCOPUS, and ProQuest for studies that met the following criteria: (i) behavioral interventions targeting BOT-PPW approximation, which (ii) were assessed using BOT-PPW-specific outcome measures, and (iiia) performed over a period of time (Review Part 1) or (iiib) studied immediate effects (Review Part 2). Study quality was rated using the GRADE framework. Data were extracted and synthesized into dominant themes. Of the 150 studies originally identified, three examined long-term effects (two single cases studies of individuals with dysphagia, and a third study evaluating effortful swallowing in healthy individuals). BOT-PPW approximation only increased in the two single case studies. Twenty-one studies evaluating immediate effects were categorized as follows: (1) effortful swallowing, (2) Mendelsohn maneuver, (3) tongue-hold maneuver, (4) super supraglottic swallowing maneuver, and (5) non-swallowing exercises. Across all studies, varying levels of success in increasing BOT-PPW approximation were reported. Four of 21 immediate effects studies evaluated patients with demonstrated swallowing impairment, whereas 17 studies evaluated healthy adults. Quality assessment revealed low strength of the existing evidence base. The evidence base for rehabilitative interventions targeting BOT-PPW approximation is severely limited and translation is hindered by small sample sizes and methodological limitations. Further clinical research is warranted.

Behavioral Interventions Targeting Insufficient Upper Esophageal Sphincter Opening During Swallowing: A Scoping Review.

The upper esophageal sphincter (UES) plays a central role in safe swallowing. Impaired UES opening is commonly observed in individuals presenting with impaired swallowing and various interventions are available aiming to improve bolus passage across the UES during swallowing. This scoping review addressed the following question: Which behavioral interventions are available to improve UES opening for deglutition? We searched MEDLINE, CINAHL, Ovid Emcare, Web of Science, SCOPUS and ProQuest for studies that met the following criteria: i. behavioral interventions targeting UES opening ii. performed over a period of time, which iii. were assessed using UES specific outcome measures. Study quality was assessed using the Joanna Briggs Institute and GRADE frameworks. Data were extracted and synthesized into dominant themes. Of the 357 studies originally identified, 15 met inclusion criteria and reported interventions that were grouped into four intervention types: (1) floor of mouth exercises that were sub-categorized into the Shaker exercise and other strengthening exercises, (2) Mendelsohn maneuver, (3) lingual exercises and (4) mixed exercise paradigms. Across the included studies, varying levels of success in improving various aspects of UES opening metrics were reported. Nine of 15 studies evaluated patients with demonstrated swallowing impairment, whereas six studies evaluated healthy adults. Quality assessment revealed significant variability in study quality, unclear reporting of participant training and treatment fidelity, as well as training dosage. The evidence base for the four behavioral intervention approaches targeting deglutitive UES opening is limited. The translation of existing evidence to clinical practice is hindered by small sample sizes and methodological limitations. Further research in this space is warranted.

Swallowing Screening: Purposefully Different From an Assessment Sensitivity and Specificity Related to Clinical Yield, Interprofessional Roles, and Patient Selection.

Purpose The purpose of this clinical focus article is to summarize the goal and process by which identification of individuals at risk for having feeding problems or dysphagia is clinically screened across the life span by speech-language pathologists (SLPs). The topic of this clinical focus article was presented at the Charleston Swallowing Conference in Chicago, Illinois, in July 2018. The contents of this clinical focus article offer an expanded summary of information discussed at this meeting with focus on critical considerations to guide clinical decisions by SLPs regarding the optimal feeding and dysphagia screening approach and process. Conclusion Screening is a critical first step in the identification of individuals at risk for feeding problems and dysphagia across the life span. Understanding the difference between screening and assessment objectives as well as having the knowledge, skills, and clinical competency to implement psychometrically sound screening approaches is a recommended clinical practice standard for SLPs working with these clinical populations. This clinical focus article summarizes critical considerations for identifying individuals at risk for feeding problems and dysphagia across the life span to guide clinicians working with dysphagia populations.

Cortical and Subcortical Control of Swallowing-Can We Use Information From Lesion Locations to Improve Diagnosis and Treatment for Patients With Stroke?

Purpose Swallowing is a complex process, mediated by a broad bilateral neural network that spans from the brainstem to subcortical and cortical brain structures. Although the cortex's role in swallowing was historically neglected, we now understand, especially through clinical observations and research of patients with stroke, that it substantially contributes to swallowing control. Neuroimaging techniques (e.g., magnetic resonance imaging) have helped significantly to elucidate the role of cortical and subcortical brain areas, in general, and the importance of specific areas in swallowing control in healthy individuals and patients with stroke. We will review recent discoveries in cortical and subcortical neuroimaging research studies and their generalizability across patients to discuss their potential implications and translation to dysphagia diagnosis and treatment in clinical practice. Conclusions Stroke lesion locations have been identified that are commonly associated across patients with the occurrence and recovery of dysphagia, suggesting that clinical brain scans provide useful information for improving the diagnosis and treatment of patients with stroke. However, individual differences in brain structure and function limit the generalizability of these relationships and emphasize that the extent of the motor and sensory pathology in swallowing, and how the patient recovers, also depends on a patient's individual brain constitution. The involvement of the damaged brain tissue in swallowing control before the stroke and the health of the residual, undamaged brain tissue are crucial factors that can differ between individuals.

Effects of unfamiliar diverse names on elementary students' passage comprehension.

Elementary school multicultural reading curricula include characters with diverse proper names, which are often unfamiliar and differ phonetically from students' native language. These names could impact reading outcomes by increasing students' cognitive load and/or creating cognitive disfluency. In Study 1, students in grades 1 through 2 read a standard passage including common names and a matched passage including unfamiliar names of Russian origin. A paired samples t test indicated unfamiliar diverse names in grade-level passages significantly reduced students' reading comprehension. Study 2 was designed to determine if preteaching diverse names would mitigate their adverse effects on reading comprehension. Results indicated second-grade students who received preteaching comprehended significantly more of the passage than those who did not receive preteaching. Discussion focuses on the need for research clarifying the relationship between multicultural learning materials and academic outcomes and validating efficient methods for familiarizing students with difficult, phonetically unfamiliar words.

Assessing Postsecondary Barriers for Rural Appalachian High School Students.

Social cognitive career theory indicates that perceived barriers negatively affect career and educational self-efficacy beliefs and may also impact interests, goals, and actions. However, measurement of barriers has produced mixed results, and few quantitative studies explore the perceived barriers of rural Appalachian students. In this series of studies, we explored the perceived educational and career barriers of rural Appalachian high school students. Our goal was to identify perceived barriers, but as initial results were analyzed, we then shifted to how best to measure barriers and how culture impacted the reporting of barriers by rural Appalachian students. The results of our mixed-method series of studies offer ideas on how cultural values and beliefs may skew reporting of contextual influences on career and education.

Building on Strengths While Addressing Barriers: Career Interventions in Rural Appalachian Communities.

This article describes a model for developing culturally-sensitive career education programs, framed from an ecological contextual understanding (Bronfenbrenner, 1979). This framework allows career practitioners to build on cultural strengths and values to meet the career education needs of diverse communities. To illustrate the application of this model, we describe the cultural context of rural Appalachia and offer theoretically-framed ideas of how to meet the population's career education needs.

Clinical Decision Making in Patients with Stroke-Related Dysphagia.

This article aims to highlight stroke considerations in the evaluation and management of dysphagia. Although dysphagia was previously thought to occur only following brainstem or bilateral cortical strokes, the development of brain imaging and dynamic swallowing studies has revealed small, unilateral supratentorial strokes can produce dysphagia. In this article, screening, evaluation, and management of dysphagia are outlined, as well as the clinical decision making that occurs when taking into account cognitive and communication deficits that may be present. For the clinical swallow examination, chart review, interview, informal evaluation of cognition and communication, observation of posture, oral cavity inspection, cranial nerve examination, and the direct swallowing assessment are reviewed along with tailoring of each according to the deficits observed. Specific compensation and rehabilitation strategies are discussed along with how cognitive and communication deficits can guide the clinician's decision-making process to select an appropriate plan of care. A case study is provided to synthesize the process into a real-world scenario.

The Relationship Between Lesion Localization and Dysphagia in Acute Stroke.

Factors that can facilitate early identification of individuals at risk of dysphagia such as stroke location are potentially of great benefit. The aim of this study was to examine the role of hemisphere and lesion location in assessing dysphagia pattern and airway invasion as identified through the use of validated, standardized interpretation measures for the videofluoroscopic swallowing study. Consecutive patients (N = 80) presenting with stroke symptoms who had a first-time acute ischemic stroke confirmed on diffusion-weighted magnetic resonance imaging (DW-MRI) scan participated. Three swallowing outcome variables were assessed using regression models: modified barium swallow impairment profile (MBSImP) oral impairment (OI) and pharyngeal impairment (PI) scores and penetration aspiration scale (PAS) score. Subjects were primarily male and demonstrated mild stroke and mild to moderate dysphagia. There was a significantly higher likelihood of abnormal PAS scores for infratentorial lesions compared to right hemisphere location (Odds ratio: 3.1, SE: 1.8, p = 0.046) and for Whites compared to African Americans (Odds ratio: 5.5, SE: 2.6, p = <0.001). However, OI scores were higher (worse) in African Americans compared to Whites (Beta = -1.2; SE: 0.56; p = 0.037). PI scores had no significant association with race or lesion location. Using DW-MRI to identify infratentorial stroke can help identify individuals at risk of airway invasion; however, imaging information concerning supratentorial infarct hemisphere and location may not be useful to predict which individuals with mild stroke are at risk for dysphagia and aspiration when admitted with acute stroke symptoms. Future studies should explore the role of race in the development of stroke-related dysphagia.

Behavioural and neurophysiological disruption of corticobulbar motor systems and their effects on sequential pharyngeal swallowing.

Primary motor networks are known to be involved in the control of voluntary oral movements as well as the modulation of pharyngeal movements during experimentally controlled single swallows performed on command. The role of these networks in the more typical task of sequential swallowing remains unexplored. This study evaluated the hypothesis that experimental disruption of motor cortical activation would reduce the rate and regularity of repeatedly performed volitional or volitionally initiated motor tasks controlled by corticospinal (finger tapping) and corticobulbar (eyebrow movement, jaw opening, volitional sequential swallowing) motor systems, but would not influence a more reflexive corticobulbar task (reflexive sequential swallowing to pharyngeal water infusion). This premise was investigated in 24 healthy participants using two techniques: a dual task paradigm and a transcranial magnetic stimulation paradigm. Disruption effects were quantified by changes in rate and regularity of performance for each tested motor task. In summary, volitional motor tasks controlled by corticospinal motor networks (finger tapping) are more susceptible to behavioural and neurophysiological disruption than tasks controlled by cortiobulbar motor networks containing a reflexive component (both volitional and experimentally initiated consecutive swallowing). Purely volitional motor tasks controlled by the corticobulbar motor system (eyebrow raising or jaw opening) were affected in similar ways as the volitional corticospinal motor tasks. In summary, tasks involving sequential pharyngeal swallowing - whether volitionally or experimentally initiated - are largely robust against disruption of primary cortical motor networks, supporting a key role of medullary CPGs in the motor control of sequential pharyngeal swallowing.

Rapid Aspiration Screening for Suspected Stroke: Part 2: Initial and Sustained Nurse Accuracy and Reliability.

OBJECTIVE: To determine registered nurses' (RNs') ability to obtain and maintain accurate procedural skills and reliable interpretation of the screening items under study to develop the Rapid Aspiration Screening for Suspected Stroke. DESIGN: Prospective, observation study. SETTING: A certified primary stroke center in a major metropolitan medical facility. PARTICIPANTS: RNs (N=15) were recruited and trained in the administration and interpretation of the screening items under study to develop the Rapid Aspiration Screening for Suspected Stroke. INTERVENTIONS: RNs completed a total of 239 screenings of patients admitted with suspected stroke over a 2-year period. RNs administered the swallowing screening items and interpreted the patient's response to each item. Independent of the RN, a speech-language pathologist simultaneously interpreted the response of the participant with stroke to each swallowing screening item. MAIN OUTCOME MEASURES: Reliability of the interpretation and accuracy of the administration of the swallowing screening items. RESULTS: The average accuracy rate for the administration of the Rapid Aspiration Screening for Suspected Stroke was 98.33%, with the overall accuracy rate for each procedural task ranging from 95.42% to 100%. For the specific swallowing screening items that formed the Rapid Aspiration Screening for Suspected Stroke, dysarthria and a positive sign after water swallow, reliability was high (k=.817). The accuracy rate for the administration and reliability of the interpretation of the swallowing screening items improved as RNs gained experience, and both were maximized at 20 screening opportunities. CONCLUSIONS: RNs demonstrate both excellent accuracy of procedural administration and reliability of interpretation of the items of the Rapid Aspiration Screening for Suspected Stroke. With feedback and repeated opportunities to practice, maintenance of skills is achievable.

Rapid Aspiration Screening for Suspected Stroke: Part 1: Development and Validation.

OBJECTIVE: To develop and validate a nurse-administered screening tool to identify aspiration risk in patients with suspected stroke. DESIGN: Validity study comparing evidence-based swallowing screening items with the videofluoroscopic swallowing study (VFSS) results. SETTING: A certified primary stroke center in a major metropolitan medical facility. PARTICIPANTS: Consecutive patients (N=250) admitted with suspected stroke. INTERVENTIONS: Patients were administered evidence-based swallowing screening items by nurses. A VFSS was completed within 2 hours of swallowing screening. MAIN OUTCOME MEASURES: Validity relative to identifying VFSS-determined aspiration for each screening item and for various combinations of items. RESULTS: Aspiration was identified in 29 of 250 participants (12%). Logistic regression revealed that age (P=.012), dysarthria (P=.001), abnormal volitional cough (P=.030), and signs related to the water swallow trial (P=.021) were significantly associated with aspiration. Validity was then determined on the basis of the best combination of significant items for predicting aspiration. The results revealed that age >70 years, dysarthria, or signs related to the water swallow trial (ie, cough, throat clear, wet vocal quality, and inability to continuously drink 90mL water) yielded 93% sensitivity and 98% negative predictive value. CONCLUSIONS: The final validated tool, Rapid Aspiration Screening for Suspected Stroke, is a valid nurse-administered tool to detect risk of aspiration in patients presenting with suspected stroke.

Using Medical Mannequins to Train Nurses in Stroke Swallowing Screening.

Screening patients admitted with stroke symptoms for risk of aspiration is often the responsibility of registered nurses (RNs). Simulation technology has become a widely used evidence-based form of training for healthcare professionals. The purpose of this study was to determine if the use of medical simulation mannequins as a training component is feasible when training and evaluating nurses administering swallowing screenings to stroke patients. A total of 32 RNs were divided into one of two training groups: didactic training only or didactic training plus simulation. Acquisition of skills was assessed immediately post-training and compared between the groups revealing significant differences between simulation group and didactic-only group for interpretation (p = 0.01) and administration (p = 0.05) accuracies. Following training to 100 % accuracy for post-training baseline competency, maintenance of skills across participants was assessed three more times over 6 weeks with the third follow-up screening completed with a standardized patient (live patient actor). While interpretation performance at each subsequent trial never equaled the baseline 100 % post-training accuracy (p = 0.001), steady improvement in performance was observed with each follow-up assessment. For screening administration, no significant differences in skills were evident between post-training baseline competency and the 6-week follow-up (p = 0.269) further confirming improvement in skills over time. Extension of screening administration and interpretation skills to the standardized patient was evident. Findings indicate that simulation training using medical mannequins can be used to train and evaluate nurses for obtainment and maintenance of swallowing screening competency.

Speech Pathology Reliability for Stroke Swallowing Screening Items.

Swallowing screening is critical in rapid identification of risk of aspiration in patients presenting with acute stroke symptoms. Accuracy in judgments is vital for the success of the screening. This study examined speech-language pathologists' (SLPs) reliability in interpreting screening items. Swallowing screening was completed in 75 individuals admitted with stroke symptoms. Screening items evaluated were lethargy, dysarthria, wet voice unrelated to swallowing, abnormal volitional cough, and cough, throat clear, wet voice after swallowing, and inability to continuously drink with ingestion of 5 and 90 ml water. Two SLPs, each with more than 10 years of experience, made simultaneous independent judgments of the same observations obtained from the screening. Overall, generally high agreement was identified between the SLPs (k[SE] = 0.83[0.03]). Individual kappas ranged from 0.38 (fair) for non-swallowing wet voice to 0.95 (almost perfect) for cough after swallow, with one item omitted due to minimal variation. SLPs demonstrate high reliability in swallowing screening. Results, however, indicate some potential variability. Items associated with trial swallows had the highest reliability, whereas items related to judgments of speech and voice quality had the lowest. Although SLPs have dedicated training and ample opportunity to practice, differences in agreement are evident. Routine practice in hospital departments is recommended to establish and maintain sensitive perceptual discrimination. If other professionals are to provide swallowing screening, knowledge of SLPs' reliability levels must be considered when identifying screening items, creating education modules, and determining acceptable levels of agreement.

Pharyngeal pressure differences between four types of swallowing in healthy participants.

PURPOSE: The aim of this observational study was to identify biomechanical differences, as measured by pharyngeal manometric pressure patterns, between discrete and continuous water swallowing, as well as volitionally initiated and reflexive swallowing. METHODS: Using pharyngeal manometry, swallowing-related pressures from 24 young healthy individuals were recorded at three locations: upper pharynx, mid-pharynx and upper oesophageal sphincter (UES) during four swallowing conditions: discrete saliva swallowing, discrete 10ml water swallowing, volitional continuous water swallowing, and reflexive continuous water swallowing. Measures of peak pressure and pressure duration at each level were compared across conditions using repeated-measures analysis of variance. RESULTS: UES nadir pressure during saliva swallowing was lower than during water swallowing conditions (p<0.05). In addition, nadir pressure during discrete 10ml water swallowing was lower than during reflexive and volitional continuous water swallowing conditions (p<0.05). Saliva swallowing produced longer pressure duration than water swallowing conditions at the upper pharynx (p<0.05). Saliva swallowing produced pressure of greater duration than reflexive continuous water swallowing at mid-pharynx (p<0.05). Further, discrete 10ml water swallowing produced longer UES opening duration and longer pharyngeal pressure generation (p<0.05) than reflexive continuous water swallowing or saliva swallowing. CONCLUSION: Pressure generation differs between swallowing types and bolus types at the level of the UES in particular. These physiological differences between swallowing and bolus types may support clinical decisions for individuals with impaired swallowing.

Improving cardiac rehabilitation attendance and completion through quality improvement activities and a motivational program.

PURPOSE: Recent studies have demonstrated that patients who attend more cardiac rehabilitation (CR) sessions have lower subsequent mortality rates than those who attend fewer sessions. METHODS: We analyzed the impact of several phased-in policy and process changes implemented to increase patient participation in CR. In March 2010, our CR program changed from a policy of individualizing the recommended number of CR sessions per patient to a policy that recommended all 36 CR sessions. In October 2010, we introduced a 7-minute video describing the benefits of CR. In August 2011, we introduced a motivational program that rewarded patients after every sixth CR session. The number of CR sessions attended was determined through review of billing records. Enrollment and completion were defined as attending ≥1 session and ≥30 sessions, respectively. RESULTS: We identified 1103 patients sequentially enrolled in CR between May 2009 and January 2012. Overall, the median number of sessions per patient improved from 12 to 20 (P < .001). Completion rate improved from 14% to 39% (P < .001). The motivational program increased attendance by a median of 3 sessions per patient (P = .04), but this effect was limited to local CR participants. Financial analysis suggested that for every $100 spent on motivational rewards, patients attended an additional 6.6 (95% CI, -1 to 14) sessions of CR. CONCLUSIONS: Quality improvement activities significantly increased CR participation. Wide implementation of such programs may favorably impact patient participation in CR and potentially decrease the rate of subsequent cardiac events.

Implementation of stroke Dysphagia screening in the emergency department.

Early detection of dysphagia is critical in stroke as it improves health care outcomes. Administering a swallowing screening tool (SST) in the emergency department (ED) appears most logical as it is the first point of patient contact. However, feasibility of an ED nurse-administered SST, particularly one involving trial water swallow administration, is unknown. The aims of this pilot study were to (1) implement an SST with a water swallow component in the ED and track nurses' adherence, (2) identify barriers and facilitators to administering the SST through interviews, and (3) develop and implement a process improvement plan to address barriers. Two hundred seventy-eight individuals with stroke symptoms were screened from October 2009 to June 2010. The percentage of patients screened increased from 22.6 in October 2009 to a high of 80.8 in March 2010, followed by a decrease to 61.9% in June (Cochran-Armitage test z = -5.1042, P < 0.0001). The odds of being screened were 4.0 times higher after implementation compared to two months before implementation. Results suggest that it is feasible for ED nurses to administer an SST with a water swallow component. Findings should facilitate improved quality of care for patients with suspected stroke and improve multidisciplinary collaboration in swallowing screening.
