Article
Full-text available
Oropharyngeal dysphagia (OD) is prevalent in the elderly and persons with complex medical conditions, resulting in considerable medical and psychosocial consequences and reduced quality of life. Many prevalence studies regard OD in relation to age or diagnosis. Knowledge on the prevalence of OD in different healthcare settings is lacking. This syst...
Article
Full-text available
Objective. To assess the effects of brain neurostimulation (i.e., repetitive transcranial magnetic stimulation [rTMS] and transcranial direct current stimulation [tDCS]) in people with oropharyngeal dysphagia (OD). Methods. Systematic literature searches were conducted in four electronic databases (CINAHL, Embase, PsycINFO, and PubMed) to retrieve...

Objective. To assess the effects of neurostimulation (i.e., neuromuscular electrical stimulation (NMES) and pharyngeal electrical stimulation (PES)) in people with oropharyngeal dysphagia (OD). Methods. Systematic literature searches were conducted to retrieve randomised controlled trials in four electronic databases (CINAHL, Embase, PsycINFO, and...
Article
Full-text available
Objective: To determine the effects of behavioural interventions in people with oropharyngeal dysphagia. Methods: Systematic literature searches were conducted to retrieve randomized controlled trials in four different databases (CINAHL, Embase, PsycINFO, and PubMed). The methodological quality of eligible articles was assessed using the Revised...

Abstract The Dysphagia Outcome and Severity Scale (DOSS) objectively assesses dysphagia via instrumental exam while considering holistically a person’s activity function: diet, nutrition and independence, as per ICF (International Classification of Functioning, Disability and Health). Although a valid and reliable scale in English, this study inves...

Full-text available
Cervical auscultation adds to the accuracy of the Clinical Swallow Examination (CSE) and ongoing clinical reviews for holistic dysphagia management and person-centred care. Literature, however, identifies the importance of the swallow-respiratory coordination and, as such, further research is needed to investigate CA validity and reliability with a...
Article
Full-text available
Purpose: Cervical auscultation (CA) uses a stethoscope or microphone to complement the clinical swallow examination by interpreting swallowing sounds and swallow-respiratory coordination. This study investigated the effects of structured CA training on CA-rating agreement with Flexible Endoscopic Evaluation of Swallowing (FEES) and CA rater reliabi...
Article
Full-text available
Purpose: Speech-language pathologists’ (SLPs) role in tracheostomy management is well described internationally. Surveys from Australia and the United Kingdom show high clinical consistency in SLP tracheostomy management, and that practice follows guidelines, research evidence and protocols. Swedish SLPs work with tracheostomised patients, however,...

Objective To identify core practices for workforce management of communication and swallowing functions in COVID-19 positive patients within the ICU. Design A modified Delphi methodology was utilized, with 3 electronic voting rounds. AGREE II and an adapted COVID-19 survey framework from physiotherapy were used to develop survey statements. Sixty-...

Abstract Introduction: Silent aspiration is a common symptom in parkinsonism, and is associated with pneumonia and poor outcomes. The aim of this study was to investigate the cough reflex test (CRT) at different stimuli strengths, and a water swallow test (WST), to screen for silent aspiration in patients with parkinsonism. Method: Seventy-six pat...

Abstract Swallowing difficulties are estimated to affect 590 million people worldwide. Food and/or fluid consistency modification is a common intervention for people with dysphagia [1]. Previous research identified that over 70 different terms were used for modified foods/fluids among Swedish SLPs (Speech Language Pathologists) reportedly negativel...

Purpose: The aim of this study was to investigate people’s experiences of living with dysphagia after stroke, and their experiences of dysphagia management. Methods: The study design was qualitative, and an open-ended approach to data collection was used, with follow-up probing questions to gain more information as needed. Personal interviews were...
Conference Paper
Introduction: Texture modified consistencies (TMC) is a common compensatory strategy to improve safety and efficiency of oral intake in dysphagia management. Lack of consensus on terminology for TMC within/between professions places a person at risk of poor oral intake, malnutrition, dehydration and aspiration. This study investigates Speech Langua...

Full-text available
Introduction: Dysphagia occurs in up to 78 % of stroke patients and greatly impacts their daily life, however little is known about patients’ experiences of living with dysphagia and of the dysphagia management received. The aim of this study was to investigate patients' experiences of living with dysphagia after stroke, and their experiences of dy...
Article
Full-text available
Purpose: Psychological distress after laryngeal cancer treatment is prevalent. Although voice rehabilitation has shown to improve functional outcomes and positively affect health related quality of life, to date there has been limited study of the associated effect of behavioural voice intervention on psychological wellbeing/distress post laryngeal...
Article
Purpose: Successful communication is influenced by communication partners, the community and communication environment. This study examines community members' perceptions of voice function following laryngeal cancer management compared to ratings by clinicians and patients. Method: Sixty-six (Tis-T3) laryngeal cancer patients post-radiotherapy,...
Article
Full-text available
Objective: Several studies have suggested that type of laryngeal biopsy may impact voice and vocal function, which may ultimately influence functional outcomes post cancer treatment. This study directly examined the impact of the biopsy procedure on voice outcomes for early glottic (Tis-T2) cancer patients. Design: Prospective pilot cohort study. M...
Article
Background To investigate potential changes in perceptual, acoustic and patient-reported outcomes over 12 months for laryngeal cancer patients treated with radiotherapy. Material and methods A total of 40 patients with Tis-T3 laryngeal cancer treated with curative intent by radiotherapy were included in this prospective longitudinal descriptive stu...
Article
Objectives/hypothesis: Laryngeal cancer and its treatment, despite management with organ-preservation treatments, is known to negatively affect voice and functional outcomes. The aim of this study was to determine whether functional outcomes and patient perceptions were improved by combining organ preservation with post treatment function rehabili...

Conference Paper
Full-text available
Objectives: Current laryngeal cancer treatment focuses upon organ-preservation, however this does not necessarily equate to function-preservation. In the absence of detailed literature, this study identifies the longitudinal changes and voice characteristics of laryngeal cancer patients treated with radiotherapy. Design: This prospective, longitudi...
Article
This prospective, single-blinded study investigated the validity and reliability of cervical auscultation (CA) under two conditions; (1) CA-only, using isolated swallow-sound clips, and (2) CSE + CA, using extra clinical swallow examination (CSE) information such as patient case history, oromotor assessment, and the same swallow-sound clips as cond...

Clinical judgements for dysphagia management were assessed under two CA conditions; (1) CA-only, using isolated swallow-sound clips, (2) CSE+CA, using extra clinical swallow examination information such...
