AI Article Synopsis
- The study aimed to systematically review the dosage of swallowing exercises used in post-stroke dysphagia intervention studies.
- Researchers reviewed 54 studies involving 1,501 participants and found inconsistencies in reporting exercise dosages, especially regarding intensity, while the most common regimen was five times per week for four weeks.
- The findings highlighted the need for improved and consistent reporting of swallowing exercise dosages in future research to better inform evidence-based practices.
Article Abstract
Purpose: To investigate the dosages of swallowing exercises reported in intervention studies on post-stroke dysphagia through systematic review.
Methods: Five electronic databases were searched from inception until February 2022 with reference tracing of included studies. Studies were included, where adults with post-stroke dysphagia received rehabilitative, behavioural swallowing exercises, pre/post outcomes were reported, and intervention dosage was described in detail, including frequency, intensity, time, and type of exercise. Two reviewers independently screened studies and rated quality using ASHA Levels of Evidence tool. Data was tabulated and narratively described.
Results: 54 studies were included with a total 1501 participants. Studies included 28 randomised controlled trials, 8 non-randomised controlled trials, 12 pre/post studies, 3 retrospective case controls and 3 case studies. Results showed inconsistent reporting of intervention dosage, with intensity the least consistently reported dosage component. While swallowing intervention was most commonly provided five times per week for four weeks, there was a wide breadth of type, frequency, intensity and duration of swallowing exercises reported. Dosage under-reporting and variation was particularly observed in "standard care" co-interventions or control groups. Study strengths included following PRISMA guidelines, providing a comprehensive review of swallowing exercise methodology and dosages, and including non-English studies. The limitation was lack of meta-analysis due to the heterogeneity of included studies.
Conclusions: Dosages of swallowing exercises are inconsistently reported and vary significantly in post-stroke dysphagia studies. Results indicate the need for consistent and comprehensive dosage reporting in dysphagia studies, and for further research into evidence-based principles to optimise swallowing exercise dosages.

Malnutrition is a significant concern for head and neck cancer (HNC) patients, as treatment often impairs mastication, causes dysphagia, and alters taste and smell, leading to reduced food intake and a diminished quality of life. Thus, this study aims to compare nutritional intake in HNC survivors using maxillofacial prostheses (MFPs) to healthy reference values and identify the factors influencing their dietary intake. The study included 56 patients treated for HNC undergoing rehabilitation with comfortable definitive dentures for over a month at the Maxillofacial Prosthetics Clinic of Tokyo Medical and Dental University Hospital.

Aims: To retrospectively evaluate the effect of a sequential swallow training programme (SSTP) consisting of nonnutritive sucking (NNS), modified feeding posture, oral sensory-motor intervention and breath exercise on the independent oral feeding transition and coordination of suck-swallow-breath (SSB) functions in preterm infants.
Methods: Sixty preterm infants received SSTP intervention and sixty infants receiving NNS were set as control. The feeding performance and SSB coordination were assessed using POFRAS and NOMAS scales.

: Oropharyngeal dysphagia is a common swallowing disorder, characterized by difficulties in moving food and liquids from the mouth to the esophagus; it is particularly prevalent among older adults with neurological conditions. This study aimed to evaluate the effectiveness of a short-term complex treatment protocol combining dietary modifications, swallowing exercises, and transcutaneous neuromuscular electrostimulation in reducing the oropharyngeal dysphagia severity and aspiration risk among geriatric patients. : A total of 64 participants aged 60 and older, with oropharyngeal dysphagia, at LSMU Kaunas Hospital between May 2021 and April 2023, were included in the study after excluding those with significant comorbidities.
