Longitudinal Change in Activities of Daily Living for Persons With Spinal Cord Injury Across 20 Years
No full textAbstract
Date Presented 4/1/2017
While all persons with spinal cord injury (SCI) decreased in their activity of daily living function over 20 yr, those with C1–C4 SCI decreased the most compared with C5–C7 and T1–S5. Based on these findings, long-term occupational therapy intervention may be beneficial, especially for individuals with C1–C4 SCI.

The Impact of the G-Code System on Medicare Part B Rehabilitation Payments for Stroke: Do the G-Codes Reduce Costs?
No full textAbstract
Date Presented 3/31/2017
We examined payments for Medicare patients with stroke before and after implementation of the new coding system to illustrate how to use propensity score matching approaches to measure the impact of payment interventions while avoiding bias due to differences in patient mix or patient severity.

Responsiveness of a Neuromuscular Recovery Scale for Spinal Cord Injury: Inpatient and Outpatient Rehabilitation
No full textUse of Item Response Analysis to Investigate Measurement Properties and Clinical Validity of Data for the Dynamic Gait Index
No full textAbstractBackground and Purpose. The Dynamic Gait Index (DGI) is a standardized clinical assessment that aids in evaluating a subject’s ability to modify gait in response to changing demands. The purpose of this study was to use Rasch measurement theory to examine whether the DGI rating scale meets suggested psychometric guidelines, whether the hierarchical order of DGI tasks is consistent with a clinically logical testing procedure, and whether the DGI represents a unidimensional construct. Subjects. Subjects were 84 community-dwelling male veterans (age range=64–88 years; mean±SD=75±6.47 years). Methods. Data were retrieved retrospectively from the participants’ clinical records. The Rasch measurement model with the WINSTEPS program was used in this study because it offers distinct advantages over traditional psychometric approaches. Results. Overall, the DGI showed sound item psychometric properties. Each of the original 4 rating scale categories appeared to distinctly identify subjects at different ability levels. The analysis revealed a clear item difficulty hierarchical order that is generally consistent with clinical expectations. In addition, fit statistics and principal components analysis indicated that the 8 items of the DGI appear to represent a single construct. Discussion and Conclusion. The results suggest that the rating scale of the DGI is used appropriately for community-dwelling older subjects with balance problems. The findings support the continued use of this well-constructed scale for clinical and research assessment in a community-dwelling population of older subjects.

Spinoza and naturalistic ethics: the adequate knowledge of the human essence to reach Beatitude
No full textEspinosa foi um filósofo racionalista do período moderno da Filosofia e estabeleceu um sistema metafísico que trouxe uma inovação na abordagem ontológica da existência de Deus e no que diz respeito ao método a ser utilizado na Filosofia. Espinosa foi, em muitos aspectos, um autor cartesiano. Seu desenvolvimento intelectual se deu através dos estudos das obras de Descartes, considerado o primeiro grande racionalista moderno, que inovou na maneira de se fazer Filosofia ao estabelecer um método com princípios semelhantes aos da Geometria. Partindo de algumas bases estabelecidas por Descartes, Espinosa desenvolveu o seu próprio sistema metafísico de modo que pudesse resolver os problemas fundamentais presentes na filosofia cartesiana, desenvolvendo a sua argumentação para além do que o filósofo francês desenvolveu, respeitando a importância de Descartes para o desenvolvimento da Filosofia, mas criticando-o no que se refere às consequências de suas teses não tão justificadas. O intuito deste projeto é propor o estudo das noções de Deus, mente e liberdade na filosofia de Espinosa, sempre considerando a influência que Descartes teve nas obras do autor holandês. Trata-se de apresentar a Teologia racional de Espinosa, na qual o autor buscou demonstrar a existência de Deus. Neste sentido, serão apresentadas as críticas de Espinosa à filosofia cartesiana, nas quais o autor holandês considera um Deus que é causa imanente e primeira do mundo; estabelece uma única substância da qual espírito e extensão são atributos; e propõe uma maneira de emancipar a humanidade a partir do conhecimento do conceito de Deus.Spinoza was a rationalist philosopher of the modern period of Philosophy and established a metaphysical system that provided a innovation in the ontological approach the he existence of God. Spinoza was, in many ways, a cartesian author. His intellectual development came from studying the Descartes’ works, considered the first great modern rationalist, who innovated the way of doing philosophy by defining a method with principles applicable like to those of geometry. Starting from some bases applied by Descartes, Spinoza makes your own metaphysical system in order to solve the fundamental problems presented in cartesian philosophy, developing his argument beyond that french philosopher, respecting the importance of Descartes for the development of the Philosophy, but making a critique of his theses that were not so well justified. The aim of this project is to propose the study of the concepts of God, freedom and mind in Spinoza’s philosophy, always considering the influence that Descartes had on the works of the dutch author. It is about presenting Spinoza’s rational theology Spinoza, in which the author sought to demonstrate the existence of God. In this sense, Spinoza’s critiques of cartesian philosophy will be included, in which the dutch author considers God to be the world’s immanent cause, and establishes a single substance of which spirit and extension are attributes; and proposes a way to emancipate humanity from the knowledge of the concept of God.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)CAPES: 88887.609848/2021-0
Creation of a short form Boston Naming Test for Individuals with Aphasia
No full textA short form Boston Naming Test (Kaplan, Goodglass, & Weintraub, 1983) has been created using Rasch analysis and responses from neurologically-healthy individuals and individuals with dementia (Graves, Bezeau, Fogarty, & Blair, 2004). Given the differences in the basis of anomia for dementia and aphasia, it cannot be assumed that this form is suitable for both populations. Thus, this study addresses 2 aims: 1) to determine if the Graves et al., (2004) short form is valid in the aphasia population and 2) based on the outcome, to create a 15-item short form with Rasch analysis using data from individuals with aphasia
