I picked an article on the prosthetic limbs, which are controlled by your own thought. The unique part of this prosthetic is that It has 26 joints, is controlled by the person’s own mind and has the power to curl up to a incredible 45 pounds. Imagine being able to control a prosthetic just by thinking about the next move. The limb has been described as Modular, which gives them the power to accommodate anyone in particular that has either the hand missing to the whole entire arm. It can be also used as a surrogate arm for those who have suffered a stroke and lost movement of their own arm. This just an incredible part of science that getting develop and study by John Hopkins University.
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

that he lost in his arm, which allowed him to send signal from the brain to the prosthetic limb. The best part about this prosthetic limb according to the Chief Engineer of John Hopkins is that it can allow them to feel some type of sensation.
This can be possible as they remapped nerves grow deeper allowing for sensation on the Modular Prosthetic Limb (M.P.L.). According to many who have had the same surgery, they are able to feel the sensation of texture. How cool is to be able to think of a movement and also feel with the same Prosthetic limb.This just the part of the testing this been doing, but want to improve till they are able to have no surgeries, and no extra implants to control the arm. They want to have a cap with sensors that will work by sending brain signals to the brain. While we wait for this in the future, they have partner to collaborate with commercial opportunities. This gives us hope we should see more M.P. L in the
future.
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
Today I am going to talk about the article “Amputees by Choice” by Carl Elliott. This topic is not about amputees in general but by people who want to cut off a healthy part of their body. Now you may ask, who in their right mind would want to do such a thing. Believe it or not, there is a condition called Body Integrity Identity Disorder (BIID). This is a mental disorder in which a person wants to amputate one or more of their healthy limbs. We then should ask, what motivates a person to want to amputate a healthy limb? There are couples of reasons or explanations for this disorder. First is that they are suffering from Body Dysmorphic Disorder, a condition in which the person believes that part of their body is diseased or ugly. The second explanation is psychosexual disorder call Acrotomophilia. This is a sexual attraction to an amputee. The last explanation is a mismatch between their bodies as they experience it.
His aim was to in-crease amputees’ confidence in the use of their prosthetics and their mental attitude. He recruited 100 volunteer amputees and put them through the programme. The results sug-gested that he achieved his aim he noted improvements in the physical and mental well-being of the volunteers. They also gained confidence in using their prosthetic which aided their recovery. Their mental well-being was particularly important as it was noted that a positive mental attitude and acceptance of the prosthetic resulted in a quicker recovery time (Dillingham, T.R., 1998).
...ter screen an arm that was placed onto his stump. When Ture Johanson saw his arm on the computer screen, he was able to control his own movements using his own neural command. In this particular study, Johanson was asked to perform numerous movements with his phantom hands such as driving a racecar. By driving a racecar, Catalan found that the subject moved muscles at the end of his existing arm to show the intent of moving his missing hand. From this study, subjects who had been experiencing PLP for several years had longer periods without pain and had shorter periods of intense pain. In addition, the phantom hand was relaxed from a tight fist to a half-open position. This study is different from others because the control signals are retrieved from the arm stump, and thus the affected arm is in charge. Moreover, it uses the signals from the damaged limbs itself.
A prosthetic is an artificial device that replaces a missing body part lost through trauma, disease, or congenital conditions. Prosthetics are becoming revolutionized to encourage amputees to pursue their highest ambitions. The technologies are progressing in prosthetics to make amputees lives more functional and the prosthetics life like.
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
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 development of prosthetic limbs is ever increasing, impacting the lives of amputees. With the rate of development in prosthetic limbs, in a few years amputees should be able too much more making it feel like they never lost a limb. Prosthetic limbs have some few problems like some of them are expensive, they can be hard to control, etc. Never the less the impact they have on amputees is ever growing making it so that the amputees feel like they have a purpose in life.
The topic I chose to discuss for this week’s topic of lower limb extremity movements is a lunge. A lunge is classified when the human body has one leg located forward with the knee bent at a 90-degree angle and keeping in line with the foot which is flat on the ground while the other leg is positioned behind, and/or when one leg is out to the side in a similar manor of 90 – degrees and keeping the knee in line with the foot which is flat on the ground, and the other leg stays facing the front. As an alternative, plyometric lunges can be achieved by jumping explosively between lunge positions. A lunge can be performed using bodyweight, dumbbells, a barbell, or kettle bells to increase strength over time and heighten the level of difficulty. Lunges tend to focus on forming and strengthening the hamstrings, quadriceps, and the gluteus maximus muscles.
...ultivating fine motor skills involving my hands. I already have the thought in my mind that our hands do so much more than we realize. The thoughts that have come through my mind if I didn't have hands. This chapter describes the hands as the primary instrument that carried out the motor commands of the brain. Any job whether it is for work or pleasure you need your hands. According to Restak the hand is best thought of as an extension of the brain. I plan on playing games on the computer or jackstraw to keep my brain-hand enhanced.
Prosthetic limbs, one of the examples of physical enhancement, have improved to such an extent that the capabilities and...
