Information gained in this investigation may be used to improve professional-family and teaming relationships and serve to benefit AAC users in school and home settings.
The purpose of this study was to describe a single case of augmentative and alternative communication (AAC) implementation. Case study methodology was used to describe the perspectives of educational team members regarding AAC implementation for Joey, a high school junior with athetoid cerebral palsy. Benefits included greater intelligibility for Joey and subsequent comfort of the staff. Facilitators of Joey's AAC system use included the team's student-focused disposition and willingness to implement use of the device, Joey's increased intelligibility, peers' acceptance of the technology, and the resulting increase in Joey's socialization. Limited team cohesiveness, problem solving, and communication were the true barriers in this case. Implications of these facilitators and barriers are discussed and recommendations for school-based AAC implementation are made.
Practitioners may consider addressing the factors that were identified as facilitators of effective programs. More research is needed concerning (a) factors promoting effective parent-professional relationships, (b) methods for increasing professional preparation in pediatric dysphagia, and (c) the efficacy of school-based pediatric dysphagia management programs.
The influence on voice quality of the insertion of endoscopic equipment with tongue anchoring and head position requirements during endoscopic evaluation has not been fully investigated. The present study attempted to examine the influence of: (1) the presence of a rigid endoscope and tongue anchoring, and (2) the angle of position technique (70-degree and 90-degree) on participants’ vocal output during sustained production of the vowel /i/. Five acoustic measurements including fundamental frequency (F₀) values, percent jitter values, relative average perturbation of F₀ shimmer, and noise-to-harmonic ratios were used to represent participants’ voice quality. Results indicated that F₀ values were significantly influenced by the angle of sitting position, while percent jitter values, relative average perturbation of F₀, shimmer, and noise- to-harmonic ratios were affected by the presence of a rigid endoscope and tongue anchoring.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
