This study concerns the possibilities of ergodiagnostics (pre-work rehabilitation), appraisal diagnostics, in the area of employment of medically handicapped people. It emphasises the value of work and being employed for the medically disadvantaged. It familiarises those interested with this matter with the means of a complete system of rehabilitation where occupational rehabilitation is irreplaceable. The study informs where legislation on (pre-work) ergodiagnostics can be found, through vocational rehabilitation we discover more detailed information and furthermore what a medically disadvantaged person should do to be able to participate actively in ergodiagnostics. It also offers a thorough overview of ergotherapy which plays an important role in diagnostics, particularly ergodiagnostics of medically handicapped people. It leads you through individual evaluations which are currently used by ergotherapists in complete rehabilitation centres where ergodiagnostics is practised. It is not only ergotherapists, however, who participate in vocational rehabilitation but a whole multi-discipline team which cooperates with job centres. The practical part is oriented on the field of ergodiagnostics or else vocational rehabilitation. Two suppositions were made for the research. The first supposition explores how well-informed people with a medical handicap are about ergodiagnostics. The second then assumes that ergodiagnostics plays a significant role in searching for suitable vacancies for the medically handicapped. The study should serve as informative material for all interested in the problem concerned. It should be especially useful to those who work with the medically handicapped and who want to have an integral view of (pre-work) ergodiagnostics, vocational rehabilitation.
