Interrater reliability in the temporal quantitative analysis of oropharyngeal swallowing using a specific software.

Purpose: This study aims to analyze inter-judge reliability by measuring a few temporal parameters of swallowing using a specific software.

Methods: Six databases that include the results of reliability tests performed in prior studies by the present research group were employed. The datasets were obtained using the same measurement method and include data obtained based on puree (level 3) consistency and liquid (level 0) consistency according to the International Dysphagia Diet Standardization Initiative.

Influence of Thermal and Gustatory Stimulus in the Initiation of the Pharyngeal Swallow and Bolus Location Instroke.

Introduction/objective: The aim of this study is to analyze the influence of sour taste and cold temperature in the initiation of the pharyngeal swallow (IPS) and bolus location at pharyngeal swallow onset in individuals after stroke.

Methods: Cross-sectional prospective study. The study included 52 individuals with unilateral ischemic stroke.

Sour taste and cold temperature in the oral phase of swallowing in patients after stroke.

Purpose: To determine the effect of sour flavor and cold temperature on oral transit time during swallowing.

Methods: Participants were 52 subjects (28 male and 24 female) with ages between 50 and 80 years (median=66 years), after ischemic stroke involving right or left side damage and mild to moderate oropharyngeal dysphagia. Videofluoroscopy was performed to analyze the swallowing times.

Components of the acoustic swallowing signal: preliminary study.

Purpose: To analyze the components of the acoustic signal of swallowing using a specific software.

Methods: Fourteen healthy subjects ranging in age from 20 to 50 years (mean age 31 ± 10 years), were evaluated. Data collection consisted on the simultaneous capture of the swallowing audio with a microphone and of the swallowing videofluoroscopic image.

The influence of sour taste and cold temperature in pharyngeal transit duration in patients with stroke.

Context: The effect of sour taste and food temperature variations in dysphagic patients has not been entirely clarified.

Objective: To determine the effect of sour and cold food in the pharyngeal transit times of patients with stroke.

Methods: Patients participating in this study were 30 right-handed adults, 16 of which were male and 14 were female, aged 41 to 88 (average age 62.

Residual signal auto-correlation to evaluate speech in Parkinson's disease patients.

Objective: To evaluate the maximum residual signal auto-correlation also known as pitch amplitude (PA) values in patients with Parkinson's disease (PD) patients.

Method: The signals of 21 Parkinson's patients were compared with 15 healthy individuals, divided according age and gender.

Results: Statistical difference was seen between groups for PA, 0.
