Rehabilitation engineers, technologists, and technicians: Vital members of the assistive technology team.

The rehabilitation engineering professions include rehabilitation engineers, rehabilitation technologists / assistive technologists and rehabilitation technicians. The purpose of this white paper is to define the rehabilitation engineering professions, describe educational pathways for the field of rehabilitation engineering, and describe the role of the rehabilitation engineering professions in a multitude of professional settings. An ad-hoc committee was convened by the Rehabilitation Engineering and Technologists (RE&T) Professional Standards Group (PSG) at the 2013 annual meeting, RESNA Conference in Seattle, Washington. The ad-hoc committee reviewed over 80 different sources in preparing the white paper, which included peer reviewed journal articles, conference proceedings, professional organization websites. Based on this review, in addition to expert opinion and stakeholder feedback, the committee developed the following definitions.Rehabilitation Engineer (RE) uses the innovative and methodical application of scientific knowledge and technology to design and develop a device, system or process, which is intended to satisfy the human needs of an individual with a disability.Rehabilitation Technologist / Assistive Technologist (RT/AT) combines scientific and engineering knowledge and methods with technical skills to complement engineering activities for an individual with a disability.Rehabilitation Technician (RTn) works with equipment, primarily assembling and testing component parts of devices or systems that have been designed by others for individuals with disabilities; usually under direct supervision of a rehabilitation engineer or rehabilitation technologist / assistive technologist. Their preferences are given to assembly, repair, or evolutionary improvements to technical equipment by learning its characteristics, rather than by studying the scientific or engineering basis for its original design.This whitepaper provides a framework for future discussions on the advancement of the rehabilitation engineering professions with the goal of improving the quality of life of individuals with disabilities through the application of science and technology.

Development of a noninvasive measure of pelvic and hip angles in seated posture.

OBJECTIVE: To develop a valid noninvasive means to measure pelvic tilt and hip angle in seated posture. DESIGN: Validation cohort study using radiographs as a criterion standard for pelvic posture. SETTING: Rehabilitation hospital. PARTICIPANTS: Volunteer sample of 10 adult men with no known physical disability. INTERVENTIONS: Radiographs were taken as subjects sat in erect, anterior, and posterior postures. An electromagnetic tracking device was as a pointer to digitize the anterior superior and posterior superior iliac spines and as a 6 degrees of freedom (df) sensor mounted on the thigh and sacrum. MAIN OUTCOME MEASURES: Variables included pelvic tilt and hip flexion angle. Intra- and interrater reliability of radiographic measures was determined by using intraclass correlation coefficient comparison of the results from 2 investigators. Validity was determined by comparing noninvasive measures of pelvic and hip angles to radiographic measures by using correlation, analysis of variance (ANOVA), and regression. RESULTS: Reliability of radiographic measures of pelvic tilt and hip angles were >/=.98. Pelvic tilt comparison: pointer: r=.89, R(2)=.80; 6-df sensor: r=.91, R(2)=.83; hip angle comparison using 6-df sensor: r=.78 with average difference of 4.25 degrees. ANOVA showed that differences between all invasive and noninvasive measures did not differ significantly (P>.05). CONCLUSION: Results indicated excellent reliability of radiographic analysis techniques and represented an improvement over previously published techniques. Noninvasive measures of pelvic tilt and hip angle were shown to be valid.
