Phantom Limb Pain (PLP) is described as a sense of pain in a non-existent extremity. This means that one who is missing their limb may feel pain which is perceived to be originating from where the original arm was. Not all cases of PLP are the same because everyone processes limb loss differently and no single injury are the same. Phantom limb pain can occur in various parts of the body and is not limited to a particular type of treatment. Similar to other illnesses, sensation vary from case to…

Paresthesia is not a disease, but a symptom of a condition that may be temporary or long-lasting. Paresthesia is a common symptom that refers to a prickling or burning sensation in some parts of the body, usually the arms, hands, legs, or feet. These can also occur in other body parts of the body. This unusual sensation, often happens without warning, and is typically painless. It may occur suddenly or gradually, but sometimes it may come and go. Other descriptions for paresthesia include…

Have you ever thought that one day you will be able to move a computer cursor, an artificial limb, or a mobile robot just by the power of your thoughts!? For normal people and people with disabilities like paralysis and limbs loss, this is a dream coming true. The goal of this research paper is to address the question of whether implantable devices can be the bright future of not only disabled people but also normal people. The paper also discusses the ethical concerns and the physical impacts…

Having been born in the nineties and growing up throughout the two thousands I took a lot of technology for granted, assuming that they have already been around for a while and that it was common for everyone to have these technologies, for example the internet, computers, and video games, but it wasn’t until I was older that I realized how fast technology was advancing, and how much new technology I took for granted as a kid. We see great ideas and new advancements in technology pop up…

individual knows there is a hand there, yet “that he does know takes some shewing [showing]” (Wittgenstein 14). Anything as far as a simple sensation should not be considered from of a hand existing. Sensations can be easily confused, for instance phantom limb pain. Consequently, sensations cannot be relied upon to prove the existence of an object. The statement “I know” entails that one has fundamental grounds of knowledge to base their statement from, excluding sensations and other body…

Prosthetic limbs have been giving people second chances at life for the last 150 years. In those 150 years prosthetic limbs have come a long way, but there is still many problems. Out of the many problems in the prosthetic limb industry, there is three main problems. The main problems include making the product available for the mass market, price of each limb, and the last problem for prosthetic limbs is advancing the technology. Although prosthetic limbs are essential for some of the people in…

It is the devastating reality that nearly two million people are currently living with limb loss in the United States. I am writing this proposal to the Amputee Coalition, because I believe that it is time to research cheaper prosthetics for these two million people. Your average prosthesis can cost anywhere from $3,000 to $50,000, and it isn’t fair to those already possessing a disability. I write this because I plan to work in rehabilitative engineering, and want to build prosthetics that…

Advancements of Prosthetics Over the Years 1 in 190 Americans are currently living with the loss of a limb, in the year 2005 1.6 million people were living with the loss of a limb (Langtree,2016). Therefore, prosthetics have advanced due to the change to lighter material, the change in mobility (movement),and the design has become more productable and useful for the amputee. “The evolution of prosthetics is a long and storied history, from its primitive beginnings to its sophisticated present,…

of the body that no longer exists. It is called Phantom Limb Pain. Many amputees agree that this pain is too much. Phantom Limb Pain occurs in 80 percent of the people who have had a limb amputated. Some amputees may experience tingling, cramping, heat, and cold in that part that has been removed. The sensations that may have been experienced before the limb was removed may be experienced to the phantom limb. A new study for Phantom Limb is acupuncture. It has shown to be an effective therapy…

from contractions, but I wonder if they can just use contractions to make an entirely new limb that can be controlled by just by contracting certain muscles, as an external prosthetic. It could be an extra arm or leg, or even finger, and even if it wouldn’t be fully controlled, it would still help with basic tasks. Basically, my question is “could a prosthetic be used to give someone a controllable extra limb?” As I began to consider the impact that prosthetics could have on places like India,…
