Neuropsychological rehabilitation: microcomputer-assisted treatment of brain-injured adults.

This study was designed to investigate the contribution of cognitive rehabilitation therapy delivered by computer within an educationally based treatment program for brain-injured adults. The effectiveness of two forms of computer-assisted neuropsychological treatment was examined, 36 head-injured adults received the treatment targeting either attention and memory skills or reasoning and logical thinking skills. Both groups were assessed on three measures of attention and memory and three measures of reasoning before and after the 8-wk. treatment. Analysis indicated significant improvement on five of six measures by both groups. No differential effect was observed by treatment condition. These findings did not support the hypothesis that computer-assisted neuropsychological rehabilitation programs which differ in both content and focus can produce specific effects on cognitive functioning of brain-injured adults.

Assessing functional status of elderly adults via microcomputer.

Geriatric adults (at least 65 years of age) completed the Functional Status Questionnaire twice, first using the original paper-and-pencil format and again using one of six computer-based interactive methods. Scoring via original and computer-based methods was identical. Satisfaction with computers was high. Of the interactive methods, touchscreen required least training and questionnaire completion time and was rated most useful.

A microcomputer-based system for auditory evoked potentials.

We have been using a microprocessor/microcomputer-based system which affords flexibility in the recording of neuroaudiologic and neurophysiologic data. To date, we have used it to record auditory sensory and neural events. Data such as spontaneous oto-acoustic emissions, evoked oto-acoustic emissions, compound action potentials, and auditory brain-stem responses can be recorded, displayed and analysed. The system hardware is configured from commercially available and 'off-the-shelf' components. The software which directs stimulus generation, data recording, data display and analysis is all written in compiled BASIC or C. A hard-disk organizational scheme has also been developed to permit ease in categorizing, storing, and using in-house or commercially available systems, utility and applications software.

Microcomputer with a sound card. Low-cost flexibility for audiometry.

An ordinary Personal Computer equipped with a sound card for entertainment electronics can significantly improve the flexibility of speech and pediatric audiometry. New programming tools have made it possible for the layman to construct his own user-interface.

Microcomputer-controlled psychoacoustics in clinical audiology.

Several commonly used psychoacoustical procedures for the evaluation of auditory function can only be carried out practically when a computer is used to control stimulus presentation. In particular, there are several procedures, such as gap detection and non-simultaneous masking, which require accurate and adaptable timing of signals which could not be conveniently carried out using manually operated or hard-wired equipment. This paper describes the development of a practical system for clinical research which is capable of carrying out a wide range of psychoacoustical procedures. The development has involved three stages: (a) General design of the system so that it is suited to the procedures envisaged; (b) design of the hardware to meet acoustical constraints such as linearity and signal-to-noise ratio; and (c) software development to provide a means for the non-expert of producing control programs with a minimum of effort. Although the system is still being improved, it is now in practical use and it is possible to produce new working control programs within a few minutes.

Microcomputer based analysis of nystagmus eye movement.

An algorithm to assist in the computation of routine peripheral nystagmus slow phase velocity (SPV) has been implemented on an Apple based data acquisition system. Waveforms stored by the computer may be output to a dot matrix printer to complement conventional strip-chart recorder output. An estimate of SPV is available after each caloric session. Analysis modes range from a summarized output for inclusion in the clinical report to a detailed beat by beat report comprising waveforms, markers and tabulated results. Problematic signals, beyond the scope of the automatic analysis, may be inspected interactively using a software controlled cursor.

A microcomputer-based research system for the optical analysis of agar-cultured micro-organism colonies.

A system which has been developed for the automatic of agar-cultured microorganism colonies is described. A camera of the line-scanning type is used to scan the plates and details of the hardware and software development are explained. Flow diagrams are included which illustrate the operation of the system, but, as yet, no results are available. The prototype machine is undergoing evaluation testing.

A microcomputer-based tachycardia termination system--a preliminary report.

A microprocessor-based system is described which employs the autodecremental mode of atrial pacing. Preliminary experience suggests that this modality of pacing retains the advantages of rapid asynchronous atrial pacing but reduces the risk of provoking resistant atrial tachyarrhythmias. If the technique continues to prove successful it is suitable for incorportation into a fully implantable pacemaker.
