摘要:

We hypothesized that extra costs incurred in meeting the requirements of wheelchair standards are recouped within the life of the wheelchair. We selected standards-quality and non-standards-quality electric wheelchairs of the same make and subjected them to accelerated life tests in a laboratory to simulate 1 year's active use. Expenses and lost time incurred due to breakdowns were monitored, and the costs of upgrading were documented. Our results support the hypothesis, within the limits imposed by the availability of only a small number of makes of electric wheelchairs of recognized standards quality. The significance of this finding is that wheelchair standards can be used to upgrade wheelchair quality in a cost-effective manner.

摘要:

The purpose of this study was to collect demographic information in 1988–1989 regarding the use of technology in disabled student services programs in higher education. Two different methods were selected: (a) the frequency of availability of 21 special services was tallied in 593 university programs across the United States, and (b) a self-administered mail questionnaire was used to gather information from 150 randomly selected programs. The rate of response to the survey was 65%; 98 questionnaires were returned from programs in 38 states. The results of the studies summarize the special services and facilities generally accessible to disabled university students, the technological assistance available, the numbers of university students having disabilities of mobility, the numbers who need assistance for computer access, and the percentage of programs identifying disabled students using electronic devices. These demographic data may shed new light on current practices related to rehabilitation technology in university settings.

摘要:

An economical video-based movement monitoring system has been developed as a tool for the non-contact monitoring of the movement patterns of persons with impaired motor function. Measurements of movements in a plane normal to the camera may be made at a rate of 50 observations per second, with a positional resolution of 0.5 min in a field of view 675 mm wide by 500 mm deep. Trials were conducted on six children with cerebral palsy and 15 age-matched children with no motor impairment. Observations were made of the trajectories of a wrist-mounted marker while subjects performed prompted switch-activation tasks. Data were analyzed in an attempt to identify characteristics that would allow subjects' intentional movements to be distinguished and recognized despite the presence of involuntary movements. Regression analysis identified two significant trajectory characteristics, the average lateral position and average direction, that were suitable for predicting which of two switches a subject was intending to activate. Intended actions were predicted with an average certainty of 88.5% for the children with cerebral palsy and 98.7% for those with no obvious impairment. More sophisticated measures may be required when attempting to recognize a larger set of unprompted switch-activation movements in the presence of other voluntary or involuntary movements. Selected combinations of movement attributes should enable deliberate actions to be more readily and accurately recognized and used for control purposes.

摘要:

This paper describes the development of a wheelchair tray system for persons with physical disabilities who require an augmentative communication system. The tray system offers advantages over existing systems by providing a convenient anterior/posterior tilt feature, a means for stowing the tray when not in use, and a method of accommodating communication systems and powered wheelchair controls. Caregivers of seven subjects fitted with the prototype system assessed its performance through the completion of questionnaires provided at the end of 6-week field trials. The technical performance of the systems was also monitored. The prototype system was favorably received by six participants. Several recommendations are made to further increase consumer acceptance of the final tray design.
