Communication Challenges

Physical and occupational therapists commonly provide services that incorporate prosthetic and orthotic devices such as crutches, canes, reachers, and ankle–foot orthoses to support mobility and activities of daily living (ADLs). Likewise, speech-language pathologists provide services incorporating prosthetic devices to support communication such as an electrolarynx, microcomputers, and mobile devices and apps with voice output capability. Assistive technology for cognition (ATC) includes the use of personal digital assistants (PDAs), tablets, and smart phones — cognitive prostheses — to compensate for cognitive challenges following acquired brain injury (ABI). Whereas funding sources for devices and services that support/compensate for mobility, ADLs, and communication challenges are generally well established, funding for ATC devices and services is relatively new to the field of speech-language pathology. This article explores the funding aspect of ATC devices and services.

Abstract Tantalum finds its largest use in the electronics industry, where it is used in filaments, filament supports, and capacitors. Metallurgical grade tantalum is used extensively in chemical process equipment. Tantalum resists corrosion by body fluids and is used in prosthetic devices. Its high melting point gives it utility in vacuum furnace components. It is also used as an alloying element in superalloys. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ta-11. Producer or source: Cabot Corporation.

Drawing on rehabilitation publications, novels by both famous and lesser-known American writers, and even the prosthetic masks of a classically trained sculptor, Great War Prostheses in American Literature and Culture addresses the ways in which prosthetic devices were designed, promoted, and depicted in America in the years during and after the First World War. The war’s mechanized weaponry ushered in an entirely new relationship between organic bodies and the technology that could both cause and attempt to remedy hideous injuries. This relationship was evident in the realm of prosthetic development, which by the second decade of the twentieth century promoted the belief that a prosthesis should be a spiritual extension of the person who possessed it. This spiritualized vision of prostheses held a particular resonance in American postwar culture. Relying on some of the most recent developments in literary and disability studies, the book’s six chapters explain how a prosthesis’s spiritual promise was largely dependent on its ability to nullify an injury and help an amputee renew (or even improve upon) his prewar life. But if it proved too cumbersome, obtrusive, or painful, the device had the long-lasting power to efface or distort his “spirit” or personality.

AbstractProsthetic arms can significantly increase the upper limb function of individuals with upper limb loss, however despite the development of various multi-DoF prosthetic arms the rate of prosthesis abandonment is still high. One of the major challenges is to design a multi-DoF controller that has high precision, robustness, and intuitiveness for daily use. The present study demonstrates a novel framework for developing a controller leveraging machine learning algorithms and movement synergies to implement natural control of a 2-DoF prosthetic wrist for activities of daily living (ADL). The data was collected during ADL tasks of ten individuals with a wrist brace emulating the absence of wrist function. Using this data, the neural network classifies the movement and then random forest regression computes the desired velocity of the prosthetic wrist. The models were trained/tested with ADLs where their robustness was tested using cross-validation and holdout data sets. The proposed framework demonstrated high accuracy (F-1 score of 99% for the classifier and Pearson’s correlation of 0.98 for the regression). Additionally, the interpretable nature of random forest regression was used to verify the targeted movement synergies. The present work provides a novel and effective framework to develop an intuitive control for multi-DoF prosthetic devices.

The Impact

BACKGROUND: The impact of paediatric upper limb difference may extend beyond the child themselves to their parents and other family members. Previous research has found that feelings of shock, numbness and loss are common amongst parents and that peer support can be a buffer against stress. OBJECTIVE: The current study aimed to explore the experiences of parents of children with limb difference, and the role of services and prosthetic devices in these experiences. METHODS: Nine parents of children with limb difference participated in either a group (n= 2) or individual (n= 7) interview. RESULTS: Analysis of the interview transcripts revealed four themes – ‘grief and guilt’, ‘prosthesis as a tool for parental adjustment’, ‘support’ and ‘fun and humour’. CONCLUSIONS: Parents may employ coping strategies to help them adjust to their child’s limb difference, including use of a prosthesis, accessing support from statutory services and peers, and use of fun and humour within the family.

Limb Injuries

Abstract‘Deck-Slap’ is an injury pattern first described at the Battle of Jutland; it is still relevant today, with anti-vehicle mines a significant threat to Coalition troops. The effect of a device exploding beneath a vehicle produces a wave of high energy that is rapidly transmitted through the steel floor; this causes significant axial loading of lower limbs often resulting in severe fractures (notably of the calcaneum). Recent advancements in orthopaedic surgery have allowed for limbs that were destined for immediate amputation following significant trauma to be salvaged. However, despite intense rehabilitation, many of these salvaged limbs have subsequently gone on to delayed amputation, as functional outcomes are often poor. Technologically advanced prosthetic devices are available that afford good quality of life and allow for increased activity levels; these devices are, however, expensive to procure and maintain. This report describes a United Kingdom (UK) Armed Forces soldier who suffered a typical ‘deck-slap’ injury in Afghanistan with subsequent limb salvage. The use of the Bespoke Off-loading Brace (BOB) is discussed. The results presented here indicate that the biomechanical function of a patient with this type of injury improves when wearing the BOB. Further studies are needed to assess long-term clinical outcomes and the functional benefit of the device as a viable and cost-effective alternative to delayed limb amputation.

Diagnosis Of Infection

Infection continues to be a major cause of morbidity and mortality worldwide. Nuclear medicine has an important role in aiding the diagnosis of particularly deep-seated infections such as abscesses, osteomyelitis, septic arthritis, endocarditis, and infections of prosthetic devices. Established techniques such as radiolabelled leucocytes are sensitive and specific for inflammation but do not distinguish between infective and non-infective inflammation. The challenge for Nuclear medicine in infection imaging in the 21st century is to build on the recent trend towards the development of more infection specific radiopharmaceuticals, such as radiolabelled anti-infectives (e.g. 99mTc- ciprofloxacin). In addition to aiding early diagnosis of infection, through serial imaging these agents might prove very useful in monitoring the response to and determining the optimum duration of anti-infective therapy. This article reviews the current approach to infection imaging with radiopharmaceuticals and the future direction it might take.
