Download or read book An Ataxia Test Battery Not Requiring the Use of Rails written by Alfred R. Fregly and published by . This book was released on 1966 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Normative standards on a new quantitative ataxia (postural equilibrium) test battery using rails of various widths as platforms were presented in a previous report. The present study reports normative standards of performance on a related battery of ataxia tests with the floor as a platform and employed routinely in the vestibular research program of this laboratory. Significant decreases in performance with age and an apparent superior performance by males were found. The scores of bilateral and unilateral vestibular-defective individuals and of patients referred for testing because of symptoms of vertigo departed significantly from the normative standards. The usefulness of individual tests as well as of the test battery in clinical and research situations was made apparent. (Author).

Download or read book Advances in Usability Evaluation written by Marcelo M. Soares and published by CRC Press. This book was released on 2012-07-09 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: Successful interaction with products, tools, and technologies depends on usable designs, accommodating the needs of potential users and does not require costly training. In this context, Advances in Usability Evaluation Part I discusses emerging concepts, theories, and applications of human factors knowledge focusing on the discovery and understanding of human interaction with products and systems for their improvement. The book covers devices and their interfaces, focusing on optimization of user devices and emphasizing visual and haptic feedback. It then discusses user studies, exploring the limits and capabilities of special populations, particularly the elderly, which can influence the design. It also examines the effect of changes in force and kinematics, physiology, cognitive performance, in the design of consumer products, tools and workplaces. Examining a variety of user-centered evaluation approaches, the concluding chapters details methods for developing products that can improve safety and human performance and at same time, the efficiency of the system. It reports on usability evaluations for different kinds of products and technologies, particularly for cellular phones, earphones, earphone controls, mattresses and pillows, package and professional tools, and service systems. The book provides new methods that enhance performance, expand capabilities, and optimize the fit between people and technology.

Download or read book Control of Posture and Locomotion written by R. Stein and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: R. B. Stein Department of Physiology, University of Alberta, Edmonton, Canada The impetus for this volume and the conference that gave rise to it was the feeling that studies on motor control had reached a turning point. In recent years, studies on motor units and muscle receptors have become increasingly detailed. Attempts to integrate these studies into quantitative models for the spinal control of posture have appeared and preliminary attempts have been made to include the most direct supraspinal pathways into these models (see for example the chapters by Nashner and Melvill Jones et al. in this volume). Thus, we felt that the time was ripe to summarize these developments in a way which might be useful not only to basic medical scientists, but also to clinicians dealing with disorders of motor control, and to bioengineers attempting to build devices to assist or replace normal control. Over the past few years, computer methods have also made possible increasingly detailed studies of mammalian locomotion, and improved physiological and pharmacological studies have appeared. There seems to be almost universal agreement now that the patterns for locomotion are generated in the spinal cord, and that they can be generated with little, if any, phasic sensory information (see chapters by Grillner and Miller et al. ). This concludes a long controversy on whether chains of reflexes or central circuits generate stepping patterns. The nature of the pattern generators in mammals remains obscure, but invertebrate studies on locomotion have recently made striking advances.

Available in PDF, EPUB and Kindle. Book excerpt: This compendium, written by active researchers in the field, encompasses topics ranging from anatomical and physiological subjects, through analyses of stimulus characteristics, prediction of sickness, and consideration of human factors, to pharmacological and behavioral therapeutic measures for terrestrial as well as microgravity travelers. Material often found scattered in diverse journals, paper-bound proceedings of symposia, difficult-to-find laboratory reports, or included with other topics in collections having a diffuse focus, are presented here in one volume dedicated to a single theme. The critical up-to-date- reviews are a first source for researchers and research program managers as well as an essential information source for engineers and practitioners.

Download or read book Transfer of Habituation of Motion Sickness on Change in Body Position Between Vertical and Horizontal in a Rotating Environment written by Ashton Graybiel and published by . This book was released on 1968 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The changing symptomatology manifested by four normal young subjects throughout exposure to rotation in a Slow Rotation Room (SRR) was used in studying susceptibility to SRR sickness and transfer effects. A comparison was made between the effects of rotation in the SRR with man parallel (vertical mode) and those when he was at right angles (horizontal mode) to the axis of rotation, the situation in a rotating spacecraft. Attention was focused on motion sickness, ataxia, and the phenomenon of transfer of habituation. Susceptibility to motion sickness was similar in the two orientational modes. With the limitations of the experiment, the findings regarding SRR sickness indicate that habituation acquired in the SRR in one mode transfers to the other mode. The postrotatory perseveration of postural habituation to the rotating environment long after cessation of rotation shed some light on the underlying homeostatic mechanism involved. (Author).
Download or read book Vestibular System Part 2 Psychophysics Applied Aspects and General Interpretations written by H.H. Kornhuber and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: The function of the vestibular system is not as obvious as those of vision, hearing, touch or smell. Vestibular dysfunction, however, is clearly apparent where lesions are present. It is probably for this reason that the vestibular sense was not discovered until the nineteenth century and that clinicians have continued to playa major role in basic vestibular research right up to the present. The relationship between basic and clinical research is certainly stronger in the vesti bular field than in that of tactile sensation, for instance, as testified by the work of clinicians as MENIERE, BREUER, BARANY, DEKLEIJN and FRENZEL. In this respect the situation is similar in vestibular physiology and in endocrinology, and for the same reason. This second part of the vestibular volume of the Handbook of Sensory Physio logy will be of interest to neurologists, otologists, neurosurgeons, ophthalmologists and physiotherapists on the one hand, and psychologists, physiologists, engineers and aviation specialists on the other. For a full understanding of Part 2, it is necessary to have assimilated the basic anatomy, physiology, and biochemistry of Part 1.
