This book was released on 2019 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major problem among people with a lower limb amputation is maintaining socket fit. Long-term and short-term changes of residual limb volume can alter socket fit resulting in pain, skin breakdown, or falls. Several strategies are used to accommodate the lost volume; however, many of these reduce the size of the socket potentially expediting long-term limb changes. Elevated vacuum (EV) has been used to maintain suspension and manage limb volume by evacuating the air between the prosthetic liner and the socket thus allowing fluid to be drawn into the limb. The physiological and mechanical effects of EV are not well understood as several research studies have evaluated the technique without a clear consensus. The aims of this dissertation were to evaluate the effectiveness of EV to manage limb fluid volume, model the mechanics of EV sockets, and optimize the effects of EV. A goal of this research was to better understand how EV functions and work towards establishing clinical guidelines for its use. The clinical effectiveness of EV to manage daily residual limb fluid volume was evaluated with an in-socket volume measurement technique during a protocol representative of daily activities. Bioimpedance analysis showed that rates of overall fluid volume change were unaffected by EV use compared to suction suspension (SS) with both conditions resulting in median rates of fluid volume loss. However, EV did reduce rates of limb fluid volume change during the final portion of the protocol after an accumulation of daily activity, suggesting benefit for high-activity users. Components of EV sockets such as liner properties, socket fit, and socket vacuum pressure interact to influence the physiological effects of EV such as limb fluid volume change and limb health. A physical benchtop model of an EV socket was developed to evaluate the ability of these EV components to influence physiology and to provide guidelines for clinical implementation of EV. Testing of this model demonstrated the ability to predict tissue vacuum pressure based on individual patient characteristics, prosthetic components, and socket fit. Additionally, the effect of EV on the residual limb tissue was found to be primarily determined by socket fit, while liner properties had minimal effect. Ideal EV parameters may differ for each individual depending on suspension needs, socket fit, prosthetic components, and health. Mechanical and physiological effects of EV were evaluated for optimizing vacuum pressure for three individuals. Multiaxial limb-socket displacement, limb fluid volume change, and user-reported socket comfort were measured at different socket vacuum pressures. Optical coherence tomography (OCT) imaging was used to measure skin perfusion at various tissue vacuum pressures, finding a potential dependency on the state of perfusion prior to vacuum application. Limb-socket displacement was the only metric to change consistently across participants. Changes to limb fluid volume and comfort suggested a more complex relationship unique to each individual. Adjusting socket vacuum pressure to balance the mechanical and physiological effects on individuals could improve EV implementation.

This book was released on 2017-09-01 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Census Bureau has reported that 56.7 million Americans had some type of disability in 2010, which represents 18.7 percent of the civilian noninstitutionalized population included in the 2010 Survey of Income and Program Participation. The U.S. Social Security Administration (SSA) provides disability benefits through the Social Security Disability Insurance (SSDI) program and the Supplemental Security Income (SSI) program. As of December 2015, approximately 11 million individuals were SSDI beneficiaries, and about 8 million were SSI beneficiaries. SSA currently considers assistive devices in the nonmedical and medical areas of its program guidelines. During determinations of substantial gainful activity and income eligibility for SSI benefits, the reasonable cost of items, devices, or services applicants need to enable them to work with their impairment is subtracted from eligible earnings, even if those items or services are used for activities of daily living in addition to work. In addition, SSA considers assistive devices in its medical disability determination process and assessment of work capacity. The Promise of Assistive Technology to Enhance Activity and Work Participation provides an analysis of selected assistive products and technologies, including wheeled and seated mobility devices, upper-extremity prostheses, and products and technologies selected by the committee that pertain to hearing and to communication and speech in adults.

What's New? The new Bare Essentials reflects recent advances in statistics, as well as time-honored methods. For example, "hierarchical linear modeling" which first appeared in psychology journals and only now is described in medical literature. Also new, is a chapter on testing for equivalence and non-inferiority. As well as a chapter with information to get started with the computer statistics program, SPSS. Free of calculations and jargon, Bare Essentials speaks so plainly that you won't need a technical dictionary. No math, all concepts. The objective is to enable you to determine if the research results are applicable to your own patients. Throughout the guide, you'll find highlights of areas in which researchers misuse or misinterpret statistical tests. We have labeled these "C.R.A.P. Detectors" (Convoluted Reasoning and Anti-intellectual Pomposity), which help you to identify faulty methodology and misuse of statistics.
