Recommended: Future and past of prosthetics
Since mankind has appeared on Earth, we have constantly been evolving. Around 50 thousand years ago making their journey out of Africa humans took a great leap forward in their development, evolving physically, intellectually, emotionally and socially. With diverse civilizations and cultures created in the wake of human advancement. Our natural interest in innovation and technology has shaped our culture and our perception of each other and the world around us. Advancements in biomedical science have allowed us to alter this perception. Starting from the creation of the prosthetic limb people who have lost their motility and dexterity were able to regain their abilities. But it doesn’t stop there, recent and future developments have created bionic and alternative prosthetics that have allowed for improved physical abilities and aesthetic appeal. Technology has allowed us new means of human expression, has gifted the unfortunate with means of re-entering society and has allowed humans to reach new heights unfathomed in the years prior.
Evidence of early uses of prostheses date back to the ancient Egyptians. Early prostheses were mainly used for function, cosmetic appearance and a psycho-spiritual sense of wholeness (Thurston). The Greeks and the Romans were the first to develop true rehabilitation aid prostheses (Thurston). In the Medieval era prostheses were primarily used for battle and hiding deformity, they were heavy and crude and made of wood, metal and leather.
Ambroise Paré revolutionized prostheses in the 16th century with his inventions of both upper and lower limb prostheses. His “Le Petit Lorrain”, a mechanical hand operated by catches and springs and an above-knee prosthesis consisting of a kneeling peg and a prosth...

Organisms are limited by the structure of their bodies. Some creatures are capable to do great things because of the number of limbs they have, or the density of their skin. Humans in particular are extremely reliant in the capabilities that our bodies bring to us. Our bodies however, are not all dependable, as we can injure ourselves, and even lose parts of our body. To combat this loss of body, the great minds of our species have created false limbs to replace what we have lost. This great improvement to our lives is known as, the prosthetic. In recent years this technology has expanded into a new form, that combines prosthetics and robotics to make life for people
In Frankenstein’s Cat by Emily Anthes, she talks about how humans change animals by biotechnology or adding limbs. The chapter “Pin the Tail on the Dolphin” discusses the many forms of prosthetics for animals. The prosthetics service animals from marine wildlife to a domesticated dog. A substantial focus zones in on a dolphin named Winter that loses her tail due to a fishing net that cut off the circulation from the tail to rest of her body. Two scientists come together to manufacture a fake tail for the dolphin. Eventually they invent a prosthetic tale that fits on Winter. Scientists even create prosthetic legs for animals such as dogs or flamingos. People construct beaks for birds and shells for turtles. Numerous uses of prosthetics benefit animals, but some seem more frivolous, like fake testicles for your neutered dog (122-142). I agree with Anthes on how prosthetics benefit animals by giving them a better life and allowing them to execute actions they could not before, but some prosthetic uses seem more for the owner’s comfort rather than
The purpose of this prosthetic limb is to help people who have lost a hand or arm in any type of accident like Les Baugh. He one of the patients currently outgoing testing with the prosthetic limb. He lost both of his arms at a electrical accident a young age and the prosthetic he using are attached to the end of his shoulders, since the accident cut his arms right to that section. He underwent surgery in order to remap the nerves
Although nothing can ever fully replace any part of our bodies, most people who have suffered the loss of a body part or who were born missing something that everyone else has and needs—like a foot or a hand—would agree that something is usually better than nothing. People have used all sorts of artificial devices probably from the beginnings of human history to help them compensate for the loss of a limb. Thus in very ancient times, the first and simplest prosthesis may have been a forked tree limb that was used as a crutch to help someone walk whose leg may have been badly damaged or lost in an accident or to a disease.
He infers this by saying, “I sat in bed and inspected the exegesis. I really needed tools to take it apart… I still found it surprising that this was as good as it got” (Barry 30). Describing it further as a bucket on a stick, feeling very wrong, and squeezing his leg so hard it feels as if all his stitches have popped (Barry 30-32). Lola Shanks, a prosthetist, assisted Charlie when learning how to use the leg. Mr. Shanks, Lola’s father, being an amputee of various limbs gives Lola the most experience in the field. Although she has the largest experience with prosthetics in the entirety of the book, the study of prosthetics is such a tiny department compared to the cancer research department, there are few options for artificial legs, arms, et cetera. In a case study in the Journal of Prosthetics and Orthotics, “Researchers have concluded…they are useful for determining the type of interventions used in rehabilitation, but that it may not accurately assess the true function of the individuals within the community” (Staubach and Sutton). Meaning although those prosthetics can be useful in rehab, once the patient is back into reality they might not be the best option. In light of this Charlie proceeds to create a leg that does suit amputees in the real world. Once Lola sees what Charlie had invented mechanically engineered legs, she sees this as a world of
They now are very useful in allowing amputees to lead a more normal life. This paper will outline the advanced technology of bionic limbs. These bionic products combine artificial intelligence with human philosophy to create a more human-like way to restore the function of a lost limb. These bionic limbs take the pressure off amputees by sensing how their lost limb should move and adapts to movement of the amputee. The bionic product automatically controls itself without the amputee having to think about how to move it. The purpose of this paper is to inform about bionic products. It will further explain how they operate, along with their efficacy in prosthetics. Innovative bionic technology continuously increases the quality of life for amputees. That innovative technology will be explored through this paper, along with their specific functions and operations. The new products like the Power Knee, the Rheo Knee, the Propio Foot, and Symbiotic leg allow more mobility and individualistic movement for the amputee. Each was developed and tested to be efficient in the prosthetic world. I will explore case studies of people who have these products. I will explore the struggles and adaptions they had to make with the use of this technology.
Recent breakthroughs in the field of genetics and biotechnology have brought attention to the ethical issues surrounding human enhancement. While these breakthroughs have many positive aspects, such as the treatment and prevention of many debilitating diseases and extending human life expectancy well beyond its current limits, there are profound moral implications associated with the ability to manipulate our own nature. Michael Sandel’s “The Case Against Perfection” examines the ethical and moral issues associated with human enhancement while Nick Bostrom’s paper, “In Defense of Posthuman Dignity” compares the positions that transhumanists and bioconservatists take on the topic of human enhancement. The author’s opinions on the issue of human genetic enhancement stand in contrast to one another even though those opinions are based on very similar topics. The author’s views on human enhancement, the effect enhancement has on human nature, and the importance of dignity are the main issues discussed by Sandel and Bostrom and are the focus of this essay.
In order to develop this prosthesis they had to go through two main phases, the analysis of a jogger wearing a standard walking prosthesis and computer simulation of the flexing of the knee on this walking prosthesis. They had to measure rotation, weight bearing, moments, and t...
The two controversial topics discussed below share a single goal: to enhance the quality of life of a human individual. The first topic, transhumanism, is a largely theoretical movement that involves the advancement of the human body through scientific augmentations of existing human systems. This includes a wide variety of applications, such as neuropharmacology to enhance the function of the human brain, biomechanical interfaces to allow the human muscles to vastly out-perform their unmodified colleagues, and numerous attempts to greatly extend, perhaps indefinitely, the human lifespan. While transhumanist discussion is predominantly a thinking exercise, it brings up many important ethical dilemmas that may face human society much sooner than the advancements transhumanism desires to bring into reality. The second topic, elective removal of healthy limbs at the request of the patient, carries much more immediate gravity. Sufferers of a mental condition known as Body Integrity Identity Disorder seek to put to rest the disturbing disconnect between their internal body image and their external body composition. This issue is often clouded by sensationalism and controversy in the media, and is therefore rarely discussed in a productive manner (Bridy). This lack of discussion halts progress and potentially limits citizens' rights, as legislation is enacted without sufficient research. The primary arguments against each topic are surprisingly similar; an expansion on both transhumanism and elective amputation follows, along with a discussion of the merit of those arguments. The reader will see how limits placed on both transhumanism and elective amputation cause more harm to whole of human society than good.
The speech that was analyzed was “Your Body Language Shape Who You Are” by social psychologist, Amy Cuddy. Amy explained in her speech that other people’s and your body language can display how a person can perceive themselves in a power dominance situation. Also, Cuddy described how an individual can change how a room of people views them by simply arranging their posture. Amy Cuddy gave an effective speech by her delivery of the topic, her credibility on the subject, and how she kept the audience engage.
Many great inventions have been made through research in biomedical engineering, for example, genetic engineering, cloning, and insulin. After insulin has been invented, there are still a lot of problems with the purity and the quantity of the insulin produced. Biomedical engineering devised a way to produce large quantities of insulin with a higher level of purity, which has saved a lot of human lives. Although biomedical engineering just been officially founded 200 years ago, its practice has been with us for centuries. According to The Whitaker Foundation website, 3,000-year-old mummy from Thebes, which uncovered by German archeologists, with a wooden prosthetic tied to its foot to serve as a big toe is the oldest known limb prosthesis and Egyptian listen to the internal of human anatomy using a hollow reed, which is what today’s stethoscope. No matter what the date, biomedical engineering has provided advances in medical technology to improve human health. These advances by biomedical engineering have created a significant impact to our lives. I have determined to become a biomedical engineer. Biomedical engineering will have a good prospect because it will become one of the most important careers in the future.
As the complexity and convenience of technology increases, some of the new advancements such as microchip implant for humans and animals can be very controversial. At first, the implants may seem to have benefits, but in the long run they will actually cause more trouble than they are worth. These potential "troublemakers" are about the size of an elongated grain of rice and are injected into the skin under the arm or hand (Feder, Zeller 15). The chip is not powered by a battery and there is nothing that can possibly leak out into the body (Posada-Swafford 8). An early form of this technology was used to monitor salmon and has been used for other wildlife research (Verhovek 5).
By convention, the field of healthcare research was entirely occupied by physicians and doctors. They were the ones who came up with new methods to treat diseases and get better results from diagnostic tests. Technology, on the other hand, was always looked at as a way to solve problems that we faced that didn’t pertain to the medical sector. It was employed to enhance the quality of life and make day to day work easier. But as technology progressed, so did the areas of application. The structural balancing techniques which were previously used to hold a building steady were now being used to develop near-perfect artificial joints and prosthetic limbs. Transparent polymers, developed to enhance robotic vision, were being suggested as a candidate for an artificial lens for the human eye. Before anyone could even understand what was happening, engineering had taken up the mantle to further medical technology to dizzying new heights.
One of the main topic Amy Cuddy talked about was about communication with body language, communicating in a non-verbal way with others but as well with ourselves. Cuddy describes how one judges on other human body language and how one can make decision based on their body language. Amy Cuddy describes situations like job interviews and promotions, where humans could make decision based on someone’s non-verbal communication. Also Amy Cuddy use the example of Nalini Ambad research that states when someone watches a mute clip of a physician attending a
