Relationships between Pathological Patterns and Quality of Life: Pathway Analysis.

Purpose. The purpose of our study was to examine the relationships between pathological patterns and self-rated quality of life (QoL). Methods.

Differences in self-rated, perceived, and acoustic voice qualities between high- and low-fatigue groups.

Objectives: The present study was performed to examine which factors among self-rated scales, perceptual evaluations, and acoustic parameters, calculated from sustained vowels, are reliable indicators of physical and mental fatigues.

Methods: A total of 73 volunteers (male:female, 52:21), aged 19-24 years, were enrolled in this study. We defined the high- and low-fatigue groups using the Chalder Fatigue Scale score.
