Impairments and disabilities--the difference: proposal for adjustment of the International Classification of Impairments, Disabilities, and Handicaps.

In this article, a proposal for adjustment of the Classification of Impairments and the Classification of Disabilities of the International Classification of Impairments, Disabilities, and Handicaps is presented. This proposal is a result of a project conducted by the Dutch National Institute for Research and Postgraduate Education in Physical Therapy. The project was executed in collaboration with the professional national organizations of five health professions: occupational therapy, chiropody, Cesar therapy (exercise therapy), Mensendieck therapy (exercise therapy), and physical therapy. The proposal includes reformulated definitions of impairment and disability, an inventory of the impairments and disabilities that are relevant for the health professions that participated in the project, a description of the domain of the Classification of Impairments and the Classification of Disabilities, a new subdivision for both classifications in chapters, and a set of "types of characteristics" and "characteristics" that subdivide the different chapters of the two classifications.

Vector diagrams in the evaluation of human gait.

From recordings of reaction forces on the feet in the vertical (z) and horizontal for-aft (x) direction during walking, x-z vector-diagrams (VDG) are constructed for the purpose of clinical use in the evaluation of gait. Such use presupposes the existence of reference values. The parameters of VDG, ie, the maximal coordinates of the vectors, are dependent on weight, speed of walking, age, step length, and physical condition. A requirement of studies on reference values is that these variables as well as height are accounted for. VDG were applied to evaluation of gait of hemiplegic subjects: slow speeds, alterations in the functions of the limbs and irregularities due to instability were noted.

Visual perception in hemiplegic patients.

Visual perceptual disturbances have been identified as a complication associated with hemiplegic syndrome that can interfere with rehabilitation progress. In this study a test battery was developed to identify visual perceptual disturbances in stroke patients. Forty-six patients (mean age 49.9 years) were first categorized according to the severity and complexity of their various impairments. This classification revealed a previously unremarked high proportion of patients who had sensorimotor disorders of the nonparetic hand and arm. Patients were subsequently tested for visual perceptual disorders, which were detected in 25 of the 46 patients. No correlations were found between the presence of these disorders and the factors of age, time since cerebrovascular accident, aphasia, and severity of the syndrome. However, significant correlations (p less than 0.01) were revealed between visual perceptual scores and disturbances in function of the nonparetic hand. The nature of the tests used to identify visual perceptual problems meant that this relationship could not be attributed to motor deficits. Possible explanations linked visual and motor systems. Left-side paretic patients performed significantly worse than right-side patients on visual perception tests, which is in accordance with earlier studies. This result was interpreted in terms of hemispheric dominance for specific functions.

Impairments and disabilities in hand therapy: the necessity of a uniform terminology for communication and research purposes.

Uniformity in the use of professional language is very important in the field of medicine. Impairments and disabilities are terms that are often used interchangeably. To health professionals analyzing a patient's health problem, formulating treatment goals, or writing questionnaires and protocols, the International Classification of Impairments, Disabilities, and Handicaps (ICIDH) offers a conceptual framework that has a great potential to remedy improper use of terms and that can enhance communication. The purpose of this article is twofold: (1) to familiarize the hand therapist with the ICIDH and (2) to present some proposals for a revision of the ICIDH that will make the classification structurally more practical and thereby will facilitate its use.
