Background: Increasing evidence supports the merits of speech therapy in Parkinson's disease, but the current practice of multiple in-house treatments is demanding for patients. We therefore assessed the effectiveness of remotely delivered and personalised speech therapy on improving quality of life and speech quality in persons with Parkinson's disease.

Methods: We performed a single blinded randomised controlled trial (the PERSPECTIVE study), comparing 8 weeks of personalised remote speech therapy to no intervention (waiting list design).

Background: A Dutch nationwide prospective cohort study was initiated to investigate recovery trajectories of people recovering from coronavirus disease 2019 (COVID-19) and costs of treatment by primary care allied health professionals.

Objectives: The study described recovery trajectories over a period of 12 months and associated baseline characteristics of participants recovering from COVID-19 who visited a primary care allied health professional. It also aimed to provide insight into the associated healthcare and societal costs.

People with Parkinson's disease (PD) experience a range of progressive motor and non-motor symptoms, that negatively affect their daily functioning, social participation and quality of life. Allied health therapies have emerged as an effective treatment approach-complementary to pharmacological and neurosurgical treatments-which reduces the impact of PD in daily life. In this article, we propose criteria for what constitutes specialized allied health care for PD, and we review allied health research in PD in terms of meeting these criteria and its outcomes for monodisciplinary approaches as well as multi- or interdisciplinary allied health interventions.

Background And Objectives: Oculopharyngeal muscular dystrophy (OPMD) is a rare progressive neuromuscular disease. MRI is one of the techniques that is used in neuromuscular disorders to evaluate muscle alterations. The aim of this study was to describe the pattern of fatty infiltration of orofacial and leg muscles using quantitative muscle MRI in a large national cohort and to determine whether MRI can be used as an imaging biomarker of disease progression in OPMD.

Background: Patients recovering from COVID-19 often experience persistent problems in their daily activities related to limitations in physical, nutritional, cognitive, and mental functioning. To date, it is unknown what treatment is needed to support patients in their recovery from COVID-19.

Objective: This study aimed to evaluate the primary allied health care of patients recovering from COVID-19 at 6-month follow-up and to explore which baseline characteristics are associated with changes in the scores of outcomes between baseline and 6-month follow-up.

Background: Persons with dementia are at risk of developing nutritional problems. Theoretical models on nutritional problems have been developed, but have not been evaluated with healthcare professionals.

Objective: This study aimed to explore the comprehensiveness and applicability of a theoretical model of nutritional problems in persons with dementia for daily nursing home practice.

Background: Females, people with young-onset PD and older individuals, and non-white populations are historically underrepresented in clinical Parkinson's disease (PD) research. Furthermore, research traditionally focused predominantly on motor symptoms of PD. Including a representative and diverse group of people with PD and also studying non-motor symptoms is warranted to better understand heterogeneity in PD and to generalize research findings.

Background: Communication difficulties are common in people with dementia, and often present from an early stage. However, direct treatment options for people with dementia that positively influence their daily communication are scarce.

Aims: To evaluate the potential impact and feasibility of a personalized logopaedic intervention.

Background: Several conditions and diseases can result in speech problems that can have a negative impact on everyday functioning, referred to as communicative participation. Subjective problems with acquired speech problems are often assessed with the speech handicap index (SHI). To assess generic participation problems, the Utrecht Scale for Evaluation of Rehabilitation-Participation (USER-P) questionnaire is frequently used.

Introduction/aims: Oculopharyngeal muscular dystrophy (OPMD) is a late-onset, progressive muscle disease. Quantitative muscle ultrasound (QMUS) assesses structural changes in muscles and is a sensitive biomarker in neuromuscular disorders. Our aim of this study was to determine whether QMUS can detect muscle pathology and can be used as longitudinal imaging biomarker in OPMD.

Background: Abnormal respiratory function tests can be observed early in the course of Parkinson's disease (PD). A better understanding of the impact of respiratory dysfunction on daily life in PD is needed to prevent later occurring complications as a (aspiration) pneumonia.

Objective: To explain which respiratory symptoms people with PD or a form of atypical parkinsonism experience and how these symptoms impact on their daily lives.

Background And Objectives: Tools to measure self-perceived communication between persons with early-stage dementia and their caregivers are lacking. Therefore, we developed a questionnaire for Experienced Communication in Dementia (ECD) with a patient version (ECD-P) and a caregiver version (ECD-C), which contains items on (a) caregiver competence, (b) social communication, (c) communication difficulties, and (d) experienced emotions. This article describes the feasibility and clinimetric evaluation of this instrument.

Background And Objectives: Oculopharyngeal muscular dystrophy (OPMD) is a late-onset, progressive muscle disease. Disease progression is known to be slow, but details on the natural history remain unknown. We aimed to examine the natural history of OPMD in a large nationwide cohort to determine clinical outcome measures that capture disease progression and can be used in future clinical trials.

Communication problems with their caregivers are common in people with dementia. Although interventions for improvement of communication are being developed, a tool to measure how participants experience their communication is lacking. The objective of this article is to describe the development of a questionnaire that measures the "experienced communication" of persons with dementia (ECD-P) as well as of their caregivers (ECD-C).

Background: Signs of respiratory dysfunction can be present already early in the course of Parkinson's disease (PD). Respiratory training could alleviate this, but its effectiveness is not well understood.

Objective: The purpose of this systematic review is to review the efficacy of different respiratory training interventions in PD.

Objective: To identify the essential elements of a newly developed, practice-based logopaedic intervention, which focuses on communication between persons with dementia (PwDs) and their caregivers.

Methods: The intervention of 6 one-hour sessions was conducted and evaluated with 4 PwD-caregiver dyads. Eighteen therapy sessions were video recorded and semi-structured interviews with all dyads and an interview with the speech-language therapist (SLT) were audio recorded.

Objective: To translate and linguistically and culturally adapt to Brazilian Portuguese, and verify the reliability and validity of the Radboud Oral Motor Inventory for Parkinson's Disease (ROMP).

Methods: The ROMP was translated and retranslated, and the instrument reliability was verified by analyzing the internal consistency and the reproducibility of the intra-examiner retest. The final version was applied to 27 participants with Parkinson's disease.

Background: Dysphagia resulting in altered food intake is common among patients with head and neck cancer. This randomized trial investigated the effect of combined individual dietary counseling with individualized swallowing therapy (intervention) compared to individual dietary counseling (control) on normalcy of food intake (NFI).

Methods: Patients with stage II to IV head and neck cancer treated with postoperative (chemo)radiation were randomly assigned to this study.
