A more nuanced understanding of the psychosocial experiences of this population may assist clinicians in providing a patient-centered approach to care. Our study was designed to gather insight into the common psychosocial experiences associated with dysphagia in the context of PD. A semi-structured interview consisting of open- and closed items was conducted with 25 individuals from regions across the country with self-reported oropharyngeal dysphagia secondary to PD. Questions were developed using comprehensive stress and coping frameworks that emphasized psychosocial predictors of specific affective reactions (e.g., grief, anxiety, depression), including self-evaluation (e.g., self-identity), coping strategies, social support, personal expectations (including perceived control over symptoms and prognosis), positive experiences, and perceptions of personal growth. Interview responses were subjected to a qualitative analysis and revealed three dominant themes: (1) Recalibration of a PD Diagnosis, (2) Vigilant Caution to Swallowing, and (3) Grieving the Loss of the Communal Meal. Using these data interpretations, we discuss three concepts for speech-language pathologists working with individuals with dysphagia and PD to consider during clinical interactions; these are reframing swallowing vigilance to engagement with mindful eating, using biofeedback to align patient perceptions and swallow physiology, and understanding the consequences of loss (of their former swallowing ability) through grief and growth reactions.</p>","PeriodicalId":11508,"journal":{"name":"Dysphagia","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141261471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of the consistency and amount of food on the behavior of these muscles was also investigated.

The normalized muscle activity (integrated EMG), duration of the muscle activity, initial activation timepoint of each muscle, and total duration of swallowing were compared among four conditions. The activity of each muscle was significantly higher during the swallowing of cookies than tofu, for 4 g vs 2 g, and for cued versus spontaneous swallowing. The duration of each muscle activity, initial activation timepoint, and total duration of swallowing were significantly longer for cookies versus tofu, for 4 g vs 2 g, and for spontaneous versus cued swallowing.

Swallowing computerized tomography (CT) has enabled three-dimensional dynamic visualization and quantitative evaluation of swallowing events providing a unique view of swallowing-related structures and their motion. Using CT, TVC closure can be visualized and evaluated on any plane or cross-section without being obscured by of laryngeal vestibule closure or epiglottis inversion. The current review summarizes the results of five papers evaluating the effects of bolus consistency and volume, posture, and age on TVC closure. The combined results of these studies suggest that TVC closure is responsive to oral sensory input based on bolus consistency and size and can be modulated in response to conditions perceived to increase the risk of airway invasion. These results are meaningful for dysphagia rehabilitation as it suggests that interventions to improve TVC closure are likely to enhance airway protection.</p>","PeriodicalId":11508,"journal":{"name":"Dysphagia","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41126994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
