1 Director, Army Prosthetics Research Laboratory, Walter Reed Army Hospital; member, Upper-Extremity Technical Committee, ACAL, NRC. The word "armamentarium" is defined as "the equipment, instruments, apparatus, or paraphernalia used by the practitioner of medicine." As applied to artificial limbs, it refers to the array of components necessary for the prescription fitting of prostheses in rela...

One of the principal activities of the members of the Biomechanics Laboratory during the past two decades has been the study of human locomotion . A major objective of these studies has been the accumulation of data that might be used in the design and construction of improved prosthetic and orthotic devices . The investigations have included electromyograms of the phasic action of muscles, for...

In this paper, we further investigate the constructions on three-dimensional(u × v × w, k, 1) optical orthogonal codes with the at most one optical pulse per wave-length/time plane restriction (briefly AM-OPP 3-D (u × v × w, k, 1)-OOCs) by way ofthe corresponding designs. Several new auxiliary designs such as incomplete holey groupdivisible designs and incomplete group divisible...

A recent survey of prosthetics practice in the U.S. revealed that upper-limb prosthetics represents a mere 5% of the work performed by the typical U.S. prosthetist. Knowing that research efforts (and dollars) will tend to be spent in a similar proportion, arm amputees might well be discouraged that their needs could be overlooked in favor of the needs of larger disabled populations. Especially ...

Globally, there are over 10 million amputees, and over fifty percent are lowerlimb amputees, according to the World Health Organization (WHO). Every year, over five-hundred thousand new lower extremity amputations result from traumatic injuries, diabetes, and other chronic diseases. In other countries with high prevalence of landmines, war, and natural disasters, trauma is the primary cause (St...

In prosthetics, as in many other fields, plastic materials were quickly adopted as soon as their usefulness was recognized, not just as a substitute for other materials, but also as a supplement in places where no other material would function as well. The plastics industry is comparatively young; not much headway was made until the start of World War II. Since then giant strides were made with...

The field of upper extremity prosthetics is a constantly changing arena as researchers and prosthetists strive to bridge the gap between prosthetic reality and upper limb physiology. With the further development of implantable neurologic sensing devices and targeted muscle innervation (discussed elsewhere in this issue), the challenge of limited input to control vast outputs promises to become ...

Introduction. Biologic, physioliogic and mechanical principles need to be considered and carefully coordinated in the establishment of the total denture design and occlusion. The aim of the authors is to share their experience with total denture treatment by patients, edentulous more than 6 years, using the method of intraoral registration of the position of the lower jaw by Gerber and arrangin...
