AI Article Synopsis

  • A mandibular kinesiograph monitored the movement of lower incisors in young adults while they read, using a microcomputer for recording and analysis.
  • The study identified a characteristic speech pattern based on incisor movement, producing an "envelope of movement" that corresponded with the subjects' incisor classifications.
  • Four distinct patterns emerged, with minor differences in speech envelope dimensions between genders, though these differences weren't statistically significant.

Article Abstract

A mandibular kinesiograph was used to monitor the movement of the lower incisors of young dentate adults reading a standard text. An interface to a microcomputer which recorded and analysed these movements. As the tracings accumulated on the computer monitor, a characteristic pattern was produced. The dimensions of this speech pattern, or envelope of movement, were measured and correlated with the subject's sex and incisor classification. Four distinct patterns were found and these correlated well with incisor classification. Small differences were noted in the dimensions of the speech envelope between men and women, but these were not significant.

Schizotypy is a multidimensional construct that is composed of positive, negative, and disorganized dimensions. Historically, disorganized schizotypy, which involves disruptions in thoughts, speech, behavior, and affect, has been relatively understudied and less clearly operationalized than the other dimensions. The present study employed experience sampling methodology to examine the associations of positive, negative, and disorganized schizotypy, as measured by the Multidimensional Schizotypy Scale, with daily life experiences.

 Many patients with neurofibromatosis type 2 (NF2) suffer from sensorineural hearing loss, and associated cochlear nerve compromise in NF2 patients makes auditory brainstem implant (ABI) an attractive treatment option. The long-term outcomes and benefits of the device are still being explored.  A retrospective review was conducted for 11 ABI recipients at a single-institution tertiary center between November 2017 and August 2022.

Purpose: Blood lactate concentration is commonly used to assess metabolic demand and skeletal muscle training response. The objective of the pilot study was to investigate if a change in blood lactate was detectable in an anaerobically designed vocal demand task vocal capacity anaerobic task (VCAT) and determine if the developed vocal demand task may assess the anaerobic capacity of the voice musculature, like anaerobic power tests commonly used in applied exercise science.

Methods: A prospective repeated measures study quantified blood lactate concentration preVCAT and postVCAT in vocally healthy adults.

Non-invasive neuromodulation methods such as transcranial Direct Current Stimulation (tDCS) and Transcranial Magnetic Stimulation (TMS), have been extensively utilized to enhance treatment efficacy for various neurogenic communicative disorders. Recently, these methods have gained attention for their potential to reveal more about the underlying nature of stuttering and serve as adjunct therapeutic approaches for stuttering intervention. In this review, we present existing research and discuss critical factors that might influence the efficacy of these interventions, such as location, polarity, intensity, and duration of stimulation, as well as the impact of combined behavioral training.
