This article summarizes the results of a recent role and function study completed in 2004 to determine the prevailing domains of disability management practice. The study also sought to establish an empirical basis for a certification exam for disability management specialists consistent with evolving standards of practice. Based on the expert panel's input, we developed a survey instrument and distributed it to a stratified, random sample of 1,500 disability management specialists. The results supported the subject matter experts' process of analysis and identification of three knowledge domains: (a) disability case management, (b) disability prevention and workplace intervention, and (c) program development, management, and evaluation. Survey results are provided, as well as implications for disability management practice.

The purpose of the study was to explore perceptual-motor differences between blind and sighted adults from a neuropsychological perspective, and to analyze the differences within the blind group. Perceptual-motor abilities were examined using Comprehensive Vocational Evaluation System (CVES), a vocational rehabilitation and neuropsychological battery designed for use with blind populations. The data were processed using Analysis of Covariance. Results showed that the sighted persons had better motor abilities, while persons with blindness were more skilled at haptic identification of shape and texture. Analysis within the blind group showed that texture identification skills are better when blindness occurs earlier in life and to the extent that blindness is total. Later onset blindness and the retention of some functional vision may not lead to a refocusing of attentional states necessary to develop haptic images. One implication of the findings is that teaching individuals who retain some functional vision to read Braille is probably counterproductive. These individuals would be better served by learning to use CCTV and large print books.
