PUB DATE 71 NOTE 319p.; Author's Masters thesis submitted to the University of Wisconsin EDRS PRICE EDRS Price MF-$0.65 HC-$13.16 DESCRIPTORS *Design Needs, Masters Theses, *Mobility Aids, *Physically Handicapped ABSTRACT Presented is a manner ot organizing and grouping performance information to support the design and development of physical movement aids for non-ambulatory persons which enable them to ambulate or at least change their position in a semiambulatory fashion. Hierarchical levels ot psychobiologic deficiency and corresponding condition variables are given for the various physically handicapping conditions which result in non-ambulation. Information on performance characteristics is intended to be used in design research for determining abilities and needs of specific non-ambulatory groups at all levels of non-ambulation and tor determining the characteristics which the proposed dynamic artificial aids must possess. A case study using the data provided is included to illustrate that a psychobiologic approach to design is possible and to indicate the type of reasoning which needs to be followed in developing design solutions.

Throughout the course of this study I tried to remain impersonal to the study's problems. I attempted to play the many roles of an interdisciplinary design team by studying the varying topical areas in literature and by discussing throughout the study with individuals having varying interests in the study's problems. Through this effort, the philosophy of most of the interests, literature concerned and applicable to the overall problems of the study were obtained. Sequentially, I collected, organized, interpreted and analyzed data in the study. I simultaneously developed a rationale to select and determine an order for the particular information required after showing how data and such an information system could be used. Once the problem was fully identified, an eight-month period of study time was broken down. It took approximately three months to collect, review and discuss literature. Another one to two months was spent organizing and identify- ing data as to how it applied to the problem goals. I simultaneously began abstracting data. I began to develop a case study strategy in which to develop design ideas for one kind of N.A. group, but before 3 completion realized that all N.A.'s couldn't use or require the same optimal device...so I stopped.Then I re- evaluated my time to redevelop a strategy in which all N.A.'s could be taken into account. Two months were then left and used to test the overall information system and to see what criteria and ideas could be developed while this presentation was prepared. This study could not have been started or accomplished without the aid of a great many friends and associates. In particular, I am deeply indebted to Dr. Darell Boyd Harmon for his personal informational guidance on the dynamic nature of the human organism and design; to Dr. Robert A. Sievert, irirector of Physical Rehabilitation rt Madison General Hospital for his informational inputs on the nature of the non-ambulatory handicapped; and Mr. Steve Kayes, a non-ambulatory student of zoology, for his insight on problems of the non- ambulatory and together for their great willingness to discuss, share their time, knowledge and advice throughout this study. I would personally like to thank Professor Byron C. Bloomfield, Professor Donald C. Hay, Professor Ali Seireg and Dr. P. Murray, Director of the Kinesiology Lab, Wood V.A. Hospital, Milwaukee, Wisconsin, for their overall guidance, support and inspiration. In addition, I would like to publicly express my appreciation to Mrs. Petra Jones, Director of Occupational Therapy, Madison General Hospital; Miss Paula Amazeen, 4 physical therapist; Dr. Robert D. Eormon, a pod/atxist; Mr. Ronald Peterson; and several of the non-ambulatory patients at Wood V.A. Hospital for their helpful comments and suggestions. Finally, I must thank Professor Stephen Wasby of the Southern Illinois University, Carbondale; and my patient wife, Paula, for a great deal of aid in preparing and making this study a reality. INTRODUC2101.:1 Problem Statement The overall problem statement or goals of this study are as follows. To first find a manner of organizing and grouping in detailed, yet logical order, information to support the development and design of physical aids and surrounds for the N.A. To be primarily concerned with an ability which most of us assume and heavily rely upon. The ability to stand, manipulate at will, and readily move or walk when and -:??1.-Jra we want our legs to go, is rarely, if ever even th:.w77at about. However, this study will extensively procee:! tc examine, understand, and identify the needs, characterise and dilemma of those who do not regard walking as an expected and subconsciously common activity. To develop alternatives and suggest a means by which th'D previously N.A. will be able to ambulate or readily raoe and change their position in at least a semiambulatory fashion. All the variables, factors, conflicts, resc,?a:c71 gaps, and interrelationships involved in determining .u1:3 developing a system (subsystems) or means of supportn, powering and controlling artificially aided locomotion will be disclosed and discussed. To attempt to resolve the question as to when where, and how do you support the human organism, in order to make the proper interface for the varying locomotive demands. The intent is to answer the question of...how can you make an walk, climb stairs, etc., when he can't do so under his own power. Thus, the task of the problem is to find and define a valid and ideal manner in which to make self-ambulation possible for those who are physiologically not capable of walking. Around these overall problem statements, I have structured and developed a research strategy which provides the basic data needed to resolve the needs that the statements imply. O 5 Definig Yon-i"mbulatory Pe_fc7,tm31e All biologic deficiencies causing conditions of unfunctional ambulation, whether they are innate, abrupt in onset, er slow to develop, will be accounted for in this study. TWO characteristics which are common to all N.A. condit!.ons need to be defined. A N.A. human organism is unable to move functionally thr=1 the vertical plane of space in a free and controlled pattern of body motion. The individual is unable to ambulate functionally under his own power or with the aiel of existing physical aids.
