Evidence-based practice is an essential element to be used clinically in speech-language pathology. Evidence-based practice (EBP) can be defined as “the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients…[by] integrating individual clinical expertise with the best available external clinical evidence from systematic research” (Sackett, Rosenburg, Gray, Haynes, & Richardson, 1996, p. 71). The purpose of evidence-based practice is to integrate clinical expertise and expert opinions, outside scientific evidence, and the values of those individuals involved to provide services that reflect upon the interests, morals, requirements, and choices of individuals being served (Introduction…show more content…
The Compendium of EBP Guidelines and Systematic Reviews includes practice guidelines where ASHA Certified Speech Language Pathologists find information concerning evidenced-based practice issues. The guidelines within the compendium have been reviewed and deemed highly recommendable or recommendable by other professionals. The systematic reviews have also been reviewed by professionals and are considered a high-quality resource for information (The N-CEP Compendium, 2015). Evidence maps are sources of information that concern a particular clinical population. Each map contains information on assessment, treatment, and service delivery of that population. Each category also contains other levels of information. Evidence maps can be clinically used to provide users with resources and guidance to make decisions using evidence-based practice (ASHA’s Evidence Maps,…show more content…
24 individuals participated in this study. 12 of these individuals had Dysarthria including 6 with Amyotrophic lateral sclerosis and 6 with Parkinson’s Disease. The other 12 were in the control group. To take part in the study, individuals were required to say five repetitions of the phrase “See a kite again” at a normal speaking rate, fast speaking rate, and a slow rate at half of their normal speaking rate. Data was recorded for articulatory movements using a three-dimensional electromagnetic articulograph and for acoustic data using a lavalier microphone. The results stated there was a strong linear interspeaker articulatory-to-acoustic relation concerning all of the participants. However, the strength relation was much weaker in those with ALS than those with PD and the control group. A strong linear intraspeaker articulatory-to-acoustic relation was found in those with PD and controls. A moderate, linear intraspeaker articulatory-to-acoustic relation was found in those with ALS. Overall, there were two important conclusions. Firstly, the predictability of vowel acoustic change seems to depend upon the degree that articulatory displacements are changed. Secondly, the degree of change in segmental duration does not inevitably predict the degree of change in tongue
