Objective: To characterize the repetitive transcranial magnetic stimulation (rTMS) induced changes in angiogenic mechanisms across different brain regions.
Methods: Seventy-nine adult male Sprague-Dawley rats were subjected to a middle cerebral artery occlusion (day 0) and then treated with 1-Hz, 20-Hz, or sham stimulation of their lesioned hemispheres for 2 weeks. The stimulation intensity was set to 100% of the motor threshold.

Clinical consensus statements (CCSs) aim to improve care for patients with Parkinson's disease (PD) and reduce the variability of rehabilitation methods in clinical practice. A literature search was conducted to find available evidence on the rehabilitation of patients with PD and to determine the scope of CCSs. The selection of PD rehabilitation domains and key questions was done using the modified Delphi method in 43 expert panels.

Methods: Sixty-nine subacute stroke patients who had taken at least 2 successive VFSSs were included. Subjects were allocated into 3 groups according to the degree of swallowing function recovery-not improved group (tube feeding recommended to patients at both studies), improved group (tube feedings recommended initially to patients and oral feeding recommended at follow-up study), and well-maintained group (oral feeding at both studies recommended to patients).
Objective: To investigate the proportion of aspiration pneumonia cases among patients with community-acquired pneumonia in Korea.
Methods: This retrospective study included patients with community-acquired pneumonia who had been admitted to the emergency department of a university-affiliated tertiary hospital in Gyeonggi Province, Korea between January 1, 2016 and December 31, 2016. Among these patients, those with aspiration pneumonia were identified using ICD-10 codes (J69.
Although children are more radio-sensitive than adults, few studies have evaluated radiation dosage during videofluoroscopic swallowing study (VFSS) in children. The aim of the study was to investigate the radiation dosage using dose-area product (DAP) for VFSS in pediatric cases and to identify factors affecting the radiation dose. Patients aged 0-17 years who had undergone VFSS were included.

Objectives: This study aimed to investigate the temporal characteristics of PA in post-stroke patients in terms of the timing of the PA event and hyolaryngeal incoordination.
Methods: Fifty-eight swallows (38 stroke patients), showing PA when swallowing a thin liquid, were included.
We investigated the progression of oropharyngeal dysphagia in patients with multiple system atrophy (MSA), with particular emphasis on MSA subtype variation. Fifty-nine MSA patients (31 MSA-P, 21 MSA-C, and 7 MSA-PC) who had undergone at least one videofluoroscopic swallowing study (VFSS) to evaluate dysphagia symptoms were included. Clinical data and VFSS findings were retrospectively evaluated using the videofluoroscopic dysphagia scale (VDS), and the results of each MSA subtype group were compared.

Methods: Swallowing was videofluoroscopically evaluated in 20 healthy volunteers in UP and LD postures, based on the movements of hyoid bone, vocal folds, and the bolus head. Parameters included the Penetration-Aspiration Scale (PAS), horizontal and vertical displacement, horizontal and vertical initial position, horizontal and vertical peak position, time to peak position of the hyoid bone and vocal folds, and pharyngeal transit time (PTT).
Background/aims: Dysphagia, a symptom of multiple system atrophy (MSA), is a major clinical concern. In this study, we investigate the characteristics of early oropharyngeal dysphagia (OD) in patients with MSA, and the differences between MSA subtypes.
Methods: Patients enrolled in the study had previously been diagnosed with MSA at the clinic of the Department of Neurology, and had been referred for a videofluoroscopic swallowing study (VFSS), between 2005 and 2014, to check for dysphagia.
The purpose of this study was to compare the swallowing function and kinematics in stroke patients with and without tracheostomies. In this retrospective matched case-control study, we compared stroke patients with (TRACH group, n = 24) and without (NO-TRACH group, n = 24) tracheostomies. Patients were matched for age, sex, and stroke-type.

We report a successful application of rTMS to the unilateral hemisphere of rat brain. The rTMS was delivered with a low-frequency (1 Hz), high-frequency (20 Hz), or sham stimulation protocol to one side of the brain by using a small 25-mm figure-8 coil.

SVM was used to classify the kinematic results as normal or dysfunctional swallowing. Various kernel functions and kernel parameters were used for optimization.

Methods: Forty-one patients with TBI were selected from medical records (between December 2004 to March 2013) and matched to patients with stroke (n=41) based on age, sex, and disease duration. Patients' swallowing characteristics were analyzed retrospectively using a videofluoroscopic swallowing study (VFSS) and compared between both groups.
Objective: To investigate the final diagnosis of patients with unexplained dysphagia and the clinical and laboratory findings supporting the diagnosis.
Methods: We retrospectively analyzed 143 patients with dysphagia of unclear etiology who underwent a videofluoroscopic swallowing study (VFSS). The medical records were reviewed, and patients with a previous history of diseases that could affect swallowing were categorized into a missed group.
Impaired swallowing in children who underwent posterior fossa brain tumor (PFBT) resection disrupts development and quality of life, yet its downstream consequences remain unclear. This study explored the risk factors and functional prognosis of postoperative swallowing impairment in pediatric patients (<19 years old) with PFBT. Among 183 patients with PFBT who underwent surgical resection, 39 patients with postoperative swallowing difficulty were analyzed using the videofluoroscopic swallowing study (VFSS).

Videofluoroscopic images of 68 patients with post-stroke dysphagia and 34 sex- and age-matched healthy controls swallowing a thin liquid were quantitatively analyzed using two-dimensional motion digitization. The measurements included the movement distances and velocities of the hyoid and larynx, and the maximal tilt angles and angular velocities of the epiglottis.

Objective: We investigated the association of fatty replacement of the supraspinatus and infraspinatus muscles with tendon tear in stroke or brain-injured patients.
The oro-esophageal tube (OE tube) is widely used in dysphagia patients although its success rate for transition to oral feeding is reported only in stroke patients. The aim of this study was to evaluate the feasibility and outcome of OE tube feeding for patients with dysphagia resulting from various etiologies. The authors reviewed the medical records of 1995 dysphagic patients that had undergone videofluoroscopic swallowing study (VFSS) in a tertiary hospital from April 2002 through December 2009.

Design: Retrospective study design.
Setting: A dysphagia clinic at a tertiary care university hospital.
The purpose of this report was to provide information for patients receiving inpatient rehabilitation after stroke and to identify the possible factors influencing functional outcome after inpatient rehabilitation. Stroke patients (n = 5,212) who were discharged from the Departments of Rehabilitation Medicine (RM) of university hospitals and rehabilitation hospitals from 2007 through 2011 were participants. Prevalence, age, transfer time after onset, length of stay (LOS), functional status at admission and discharge were analyzed.

A total of 132 patients with stroke, traumatic brain injury, or brain tumor in 2 university hospitals were allocated to 2 groups: those who received electrical stimulation therapy (EST) on the suprahyoid muscles (SM group, n = 66) and those who received EST with one pair of electrodes on the suprahyoid muscle and the other pair on the infrahyoid muscle (SI group, n = 66). Patients received 11.

This retrospective case series included five patients who underwent surgical resection of the cervical anterior osteophyte due to dysphagia. Videofluoroscopic swallowing studies (VFSSs) were performed before and after surgery on each patient, and kinematic analysis of the video clips from the VFSS of a 5-mL liquid barium swallow was carried out. Functional oral intake improved after surgery in 3/4 patients who had required a modified diet before surgery.
