The aim of this study was to investigation of the relationship between knee and ankle angles and squat/countermovement jump heights at the age group of 15-17 swimmers. 10 girls (mean age 15.30±0.48yrs, mean height 165.00±5.33cm, mean mass 49.60±5.10kg) and 13 boys (mean age 16.00±1.00yrs, mean height 178.00±7.32cm, mean mass 64.31±7.35kg) were…

Purpose: Within-individual pharyngeal swallowing pressure variability differs among pharyngeal regions in healthy individuals and increases with age. It remains unknown if pharyngeal pressure variability is impacted by volitional swallowing tasks. We hypothesized that pressure variability would increase during volitional swallowing maneuvers and…

Purpose: This study compared the concordance between two validated videofluoroscopic pharyngeal residue outcome scales used in clinical and research settings: the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) and the Analysis of Swallowing Physiology: Events, Kinematics and Timing (ASPEKT) percent residue metric. Method: Two trained raters…

Purpose: The primary purpose of this study was to validate common respiratory calibration methods for estimating lung volume in children. Method: Respiratory kinematic data were collected via inductive plethysmography from 81 typically developing children and nine children with neuromotor disorders. Correction factors for the rib cage and abdomen…

Purpose: Thickened liquids are frequently used as an intervention for dysphagia, but gaps persist in our understanding of variations in swallowing behavior based on incremental thickening of liquids. The goal of this study was to establish reference values for measures of bolus flow and swallowing physiology in healthy adults across the continuum…

Purpose: The aim of the study was to update our information regarding the salpingopharyngeus (SP) muscle using cadaveric and in vivo magnetic resonance imaging (MRI) data. Primary objectives were to (a) observe the presence/absence of the muscle and (b) quantify and describe its dimensions and course. Method: SP specimens from 19 cadavers (10…

This pilot study investigates the feasibility and assesses the impact of "Lactobacillus plantarum" PS128 probiotics on the neurological function in Rett syndrome. We conducted a randomized, double-blind, and placebo-controlled trial on Rett syndrome with MECP2 mutation aged between 1 and 50 years in Taiwan. In this pilot study,…

Purpose: Dysphagia is one of the most debilitating chronic symptoms experienced by patients who undergo radiation treatment for head and neck cancer. Despite the high prevalence of dysphagia in patients with head and neck cancer, we lack understanding of the specific changes in swallowing physiology that arise in the short-term following radiation…

Purpose: To date, research characterizing swallowing changes in individuals with amyotrophic lateral sclerosis (ALS) has primarily relied on subjective descriptions. Thus, the degree to which swallowing physiology is altered in ALS, and relationships between such alterations and swallow safety and/or efficiency are not well characterized. This…

Purpose: This study has two key aims--first, to provide developmental articulatory norms for the alveolar-velar distinction in 30 English-speaking typically developing (TD) children; second, to illustrate the utility of the reported measures for classifying and quantifying the speech of children with a history of persistent velar fronting as they…

The purpose of this study was to compare the muscle activation of singers and instrumentalists while performing simple vocal exercises. Volunteer participants (N = 28) were undergraduate music majors and minors, with an equal number being vocalists and instrumentalists. Participants performed five vowel sounds (ah, eh, ee, oh, oo), while…

The overarm throw is a difficult multi-limb task because the overarm throw requires synchronized dexterity of the entire body. Research has determined that the inability to throw hinders children's participation in physical activities. The dynamic systems theory, which describes the interactions and processes that manipulate development, framed…

Purpose: This tutorial summarizes current best practices in treating American English /r/ distortions in children with residual speech errors. Method: To enhance the effectiveness of clinicians' cueing and feedback, the phonetics of /r/ production is reviewed. Principles of acquisition, which can inform how to practice /r/ in the early stages of…

Background: Limited research has examined health and fitness indicators among individuals with different categories of intellectual disabilities (ID). The purpose of this brief report was to examine differences in health and physical fitness indicators among individuals with different levels of ID. Method: Individuals (n = 203) with mild,…

Purpose: This study investigated whether metabolic respiratory requirements (treadmill workload) affected glottal valving in phonation, based on aerodynamic measures, when a sound pressure level (vocal SPL) is dictated as a target goal. Consistent with a theory of action, we hypothesized that adjustments in glottal valving as measured by laryngeal…
