Measuring the outcomes of assistive technology: challenge and innovation.

Documenting outcomes is becoming an essential function in assistive technology. Successfully documenting outcomes, however, depends on having appropriate measurement instruments and methodologies available. This is a challenge, as few measures are available which target the measurement of assistive technology outcomes. New instrumentation and approaches may need to be created or older measures radically adapted for assistive technology applications. This paper reviews measurement issues specifically relevant to assistive technology outcomes assessment. Many of the issues relate to measurement theory, as it is important to understand how instruments based on traditional psychometric concepts may not be the most appropriate for applications of assistive technology outcomes assessment. Fortunately, the assistive technology field also has innovative ideas being developed and tested. These may hold some promise as we all pursue better ways to document the outcomes of our assistive technology devices and services.

An analysis of computer-related articles in occupational therapy periodicals.

The introduction of personal computers in the late 1970s and early 1980s has affected occupational therapy. Nine journals, three trade newspapers, and one series book published over an 11-year period by four English-speaking countries were catalogued for articles pertaining to computer use in occupational therapy. This investigation yielded 174 articles that were categorized by information type, application of computers covered, sophistication of technology, computer brand, and country of publication. Most articles provided general information, described clinical training applications, used an Apple computer, and were from an American publication. Few articles were reports of research. The percentage of computer-related articles has substantially increased in the observed 11-year period. These findings indicate increased computer use in occupational therapy.

The development of technology competencies and training guidelines for occupational therapists.

The ability to use technology has become a survival skill in our society. This paper discusses technology trends related to the demands of the Information Age, the increasing availability of information and assistive technologies, and the impact of recent civil rights legislation mandating that persons with disabilities be given equal access to technologies that can enhance functional performance. Occupational therapists must become competent in the application and integration of these technologies into reasonable accommodation interventions if we are to meet the changing needs of persons with disabilities. To address this need for technology training, a multitiered set of technology competencies specifically designed for occupational therapy practitioners was authored by the American Occupational Therapy Association Technology Special Interest Section and reviewed by occupational therapists with technology expertise. The process of developing these competencies and recommendations for implementing them within occupational therapy educational programs are discussed.

Computer-assisted functional assessment and documentation.

Occupational therapy personnel spend considerable time on functional assessment and documentation. The rapid and error-free information processing ability of computers offers methods for data collection, clinical decision making, and reporting of functional assessment results, which may be more effective and efficient than the current paper-and-pencil methods. Computers can provide assistance throughout the many steps of the functional assessment and reporting process. Software is available to assist in direct data collection, data reduction, and analysis, or to assess complex data systems and databases. Additionally, computers can use assessment techniques, such as dynamic question sets and expert systems, which have not been possible with paper-and-pencil methods. Furthermore, data collected on computers are readily available to be integrated in computer-assisted report writing and can be compiled into large databases for analysis. These databases can be used for program evaluation, continuous quality improvement exercises, and other research objectives. This paper provides a snapshot of these computer uses in the assessment process.

Use of adjunctive modalities in occupational therapy.

This article reminds us that as practice evolves, we must revisit and reaffirm the fundamental philosophy and precepts in which our profession is grounded. The face of practice is fluid. Its superficial appearance is molded by external forces and stresses. These include the changes in the needs of the persons we serve, the emergence of new and different treatment modalities, and the realities of the socioeconomic environment in which we work. Beneath the surface, however, are the basic structures that all of us hold in common. These are our philosophical beliefs that are articulated both in the professional literature and in the ethical principles that we espouse.

Effectiveness of a writing system using a computerized long-range optical pointer and 10-branch abbreviation expansion.

Many individuals with limited abilities require specialized technological writing systems. These individuals and the clinicians and engineers who work with them need information regarding the effectiveness of various systems. This study developed a methodology for assessing the effectiveness of a technological writing support system and evaluated its success. The Long-Range Optical Pointer and 10-Branch Abbreviation Expansion System developed at the Trace R&D Center at the University of Wisconsin was used. The study applied a single subject research design: a series of AB replications with naturally-occurring baselines comparing data within subjects across behavior, and across subjects. Behaviors assessed included typing rate, efficiency, and accuracy. The results demonstrate the effectiveness of this system with four individuals with severe physical disabilities and one able-bodied person. Among the data collected, typing rates were found to range from 3 to 15 words per minute, with suspected dependency on familiarity with the system. Discussion highlights the potential benefits of this system and the critical requirement to individually assess a person's needs in order to appropriately select and prescribe these types of technology. The need for further application-oriented single-subject research as well as classical human factors research is emphasized.

The effects of introducing the Klein-Bell ADL Scale in a rehabilitation service.

This study investigated the impact of introducing the Klein-Bell ADL Scale into a rehabilitation medicine service. A pretest and a posttest questionnaire of rehabilitation team members and a pretest and a posttest audit of occupational therapy documentation were completed. Results of the questionnaire suggested that the ADL scale influenced rehabilitation team members' observations in the combined area of occupational therapy involvement in self-care, improvement in the identification of treatment goals and plans, and communication between team members. Results of the audit suggested that the thoroughness and quantification of occupational therapy documentation improved. The clinical implications of these findings recommend the use of the Klein-Bell ADL Scale in rehabilitation services for improving occupational therapy documentation and for enhancing rehabilitation team effectiveness.

Pinch and grasp strength: standardization of terminology and protocol.

We implemented a tridirectional survey to begin the standardization process for grasp and pinch terminology and protocols for testing and to improve the communication between rehabilitation professionals who assess hand strength. We surveyed the literature, occupational therapy clinics across the country, and occupational therapy educational programs. Our results reveal the current use, teachings, and recommendations of pinch and grasp strength measurement. The results confirm that the standardization of grasp and pinch terminology and protocols for testing are vitally needed. Specific recommendations to continue this standardization process are recommended.

Checklist for the prescription of slings for the hemiplegic patient.

The wide variety of hemiplegic sling designs, the lack of a uniform approach to sling selection, and the paucity of research data in this area have tended to make prescribing a sling a subjective process. Based on clinical experience and a comprehensive literature review, the authors propose a checklist for examining hemiplegic slings. The Checklist, which includes 19 desirable and 4 undesirable characteristics of slings, provides a more objective basis for comparing sling designs, warns of potential hazards, and facilitates the thorough examination of hemiplegic slings. The uses and limitations of the Checklist are discussed.

Submucosal cordectomy for laryngeal stenosis.

Submucosal cordectomy, an old procedure first described for the treatment of bilateral abductor vocal cord paralysis, was used to relieve glottic or minimal subglottic stenosis in four patients. Three attained adequate airways with no further procedures; one required subsequent dilations for granulation tissue after which decannulation was successfully effected. Although airway restoration has been successful, the resultant voice has been poor, poorer than that usually achieved with arytenoidectomy. When cricoarytenoid scarring precludes arytenoidectomy and lateral vocal cord fixation, an adequate laryngeal lumen can be restored with submucosal cordectomy if sufficient laryngeal cartilage support remains.

Retrognathia and sleep apnea. A life-threatening condition masquerading as narcolepsy.

The association of sleep apnea with daytime hypersomnolence without obesity, and its potentially lethal cardiopulmonary sequelae, make it crucial that this condition be distinguished from narcolepsy. A patient with retrognathia who had been diagnosed as a narcoleptic for 15 years had the primary complaint of excessive daytime sleepiness. Sleep laboratory evaluation showed severe hypoxemia and a mean of 366 upper airway obstructions per night. The patient was treated with a tracheotomy; this resulted in relief of the sleep-related upper airway obstructions, hypoxemia, and hypersomnolence.

Sleep apnea, hypersomnolence, and upper airway obstruction secondary to adenotonsillar enlargement.

The authors examined four children with substantial adenotonsillar enlargement that caused intermittent severe upper airway obstructive episodes, documented by all-night polygraphic monitoring of sleep and respirations. Previously unreported complications of severe adenotonsillar enlargement that were demonstrated included prolonged obstructive apneic episodes and disturbed sleep patterns. The children also exhibited daytime hypersomnolence. Polygraphic sleep studies after adenotonsillectomy confirmed improved sleep patterns and relief of the obstructive episodes. None of our patienqs had developed pulmonary hypertension, cor pulmonale, or other reported complications of prolonged upper airway obstruction, all of which may have been averted by early diagnosis and treatment.

Rhabdomyoma of the pharyngeal wall.

Rhabdomyoma is a rare benign tumor of skeletal muscle, and the head and neck region is the most common extracardiac area for these tumors to occur. Twenty-one cases have previously been reported, and this report, "A Rhabdomyoma of the Pharyngeal Wall," brings the total to 22. Pathologically, these tumors show abundant polygonal skeletal muscle cells with demonstrable cross striations. Differential diagnosis of these tumors has included granular cell myoblastoma and rhabdomyoscarcoma. Treatment is usually complete excision.
