Book excerpt: Since the advent of the first modern below-knee prosthesis (joint and lacer) in 1696, the world has seen unprecedented advances in virtually every facet of medical science, yet limb discomfort, pain, and soft tissue breakdown remain a way of life for roughly half of todays ambulatory, below-knee (transtibial) amputees. These largely avoidable daily struggles are traceable to poorly crafted limbs, ill-designed prostheses, and/or inadequate upkeep of them. Fortunately, the solution to the majority of these struggles is clear-cut and entirely achievable. Primarily, it requires a team effort by surgeons, prosthetists, and amputees: as each has a unique role to play. Surgeons must employ the latest surgical principles to optimize the limb for prosthetic use (Chapter 2), prosthetists must implement the latest design principles to create a responsive, comfortable, and pain-free socket interface (Chapter 4), and amputees must follow the guidelines to maintain their optimized limb and prosthesis (Chapter 5). However, as discussed in Chapter 2, certainty of a pain-free interface will also require a commitment by researchers to find solutions to the yet unresolved surgical issues (e.g. neuromas and bone spurs). While one can never expect the socket interface to perfectly replace the responsive and pain-free connection lost during amputation, finding solutions to the unresolved surgical issues, and following the latest principles and guidelines discussed in this book unquestionably offers transtibial amputees with their best chance of achieving the active, comfortable, pain-free, and productive lifestyle they deserve.

Book excerpt: The prosthetic socket, the mechanical interface between an amputated residuum and an external prosthesis, is of critical importance to the performance of a prosthetic limb system. Conventional prosthetic socket technology is derived using a non-quantitative, artisan methodology. Consequently, a comfortable socket interface cannot be made reproducibly, and persons with limb amputation too often experience discomfort. As a resolution to this difficulty, the field of digital prosthetic socket design seeks to advance a quantitative CAD/CAM methodology for socket production to produce reproducible and comfortable interfaces. Prosthetic researchers have proposed a digital socket production work flow comprising the steps of 1) assessment of residuum tissue biomechanics; 2) modeling optimization of the residuum-socket interface, and 3) fabrication of a variable-impedance socket system based upon these optimizations. In this thesis, two novel technologies are designed, built and evaluated at either end of this work flow, namely a multi-indenter device for in vivo biomechanical tissue measurement and a quasi-passive variable-impedance transtibial socket interface. An active indenter platform called the FitSocket is presented. To assess residual-limb tissue biomechanics, the FitSocket comprised 14 position and force controllable actuators that circumferentially surround a biological residuum to form an actuator ring. Each actuator is individually controllable in position (97.1?m accuracy) and force (330mN accuracy) at a PC controller feedback rate of 500Hz, allowing for a range of measurement across a residuum. At five distinct anatomical locations across the residual limb, force versus deflection data are presented, demonstrating the accuracy and versatility of the FitSocket for residual limb tissue characterization. A passive, single indenter version of the FitSocket, called the FitPen, is also presented. The FitPen is designed to be ultra-portable in order to take biomechanical measurements in the field outside the laboratory setting. A quasi-passive socket (QPS) is presented having spatially and temporally varying socket wall impedances. The QPS is an autonomous computerized transtibial prosthetic interface that can stiffen or become compliant using computer-controlled electrolaminate actuators. The QPS measures forces applied by the limb on the socket, 3-axis acceleration of the socket, and the position of the electrolaminates. On a test participant with transtibial amputation, the socket was evaluated through sit-to-stand tests to determine the viability of computer-controlled electrolaminate engagement, and through a walking study to evaluate the ability of the electrolaminates to maintain their clutched state during ambulation at a self-selected walking speed. The average deflections of forced tibia movement in the sit-to-stand tests were 7 ± 2 mm while sitting with the electrolaminates in an unclutched state, and 2.1 ± 0.6 mm while standing with the electrolaminates in a clutched state. Further, the walking study showed a maximum unclutched deflection (3.7 ± 0.9 mm)16 times larger than that of the maximum deflection while clutched. This work was supported by the United States Department of Veteran Affairs through the VA Innovation Initiative (VAi2) program.

Download or read book Wearable Robots written by José L. Pons and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wearable robot is a mechatronic system that is designed around the shape and function of the human body, with segments and joints corresponding to those of the person it is externally coupled with. Teleoperation and power amplification were the first applications, but after recent technological advances the range of application fields has widened. Increasing recognition from the scientific community means that this technology is now employed in telemanipulation, man-amplification, neuromotor control research and rehabilitation, and to assist with impaired human motor control. Logical in structure and original in its global orientation, this volume gives a full overview of wearable robotics, providing the reader with a complete understanding of the key applications and technologies suitable for its development. The main topics are demonstrated through two detailed case studies; one on a lower limb active orthosis for a human leg, and one on a wearable robot that suppresses upper limb tremor. These examples highlight the difficulties and potentialities in this area of technology, illustrating how design decisions should be made based on these. As well as discussing the cognitive interaction between human and robot, this comprehensive text also covers: the mechanics of the wearable robot and it’s biomechanical interaction with the user, including state-of-the-art technologies that enable sensory and motor interaction between human (biological) and wearable artificial (mechatronic) systems; the basis for bioinspiration and biomimetism, general rules for the development of biologically-inspired designs, and how these could serve recursively as biological models to explain biological systems; the study on the development of networks for wearable robotics. Wearable Robotics: Biomechatronic Exoskeletons will appeal to lecturers, senior undergraduate students, postgraduates and other researchers of medical, electrical and bio engineering who are interested in the area of assistive robotics. Active system developers in this sector of the engineering industry will also find it an informative and welcome resource.
