Robotic Arm for Amputees: Reflective Paper My project has to do with robotic arms for amputees and ways I could help improve them. I chose this topic because I have always been interested in the human body and medical innovations. Now I really did not know much about prosthetic limbs or robotics, but it did interest me greatly, so I was willing to learn. Through my work I learned that there are more than one type of robotic prosthetic arms and the different ways of making them move. For example you can either connect the arm to the remaining muscles that are left in the amputated arm or you can connect it directly to the brain using the electric signals to communicate with the robotic arm. There were some problems that I did run into, one being
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.
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.
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.
Prosthetics (pronounced prahs-THEH-tiks) is the branch of medicine that deals with the artificial replacement of a missing body part. A prosthesis (pronounced prahs-THEE-sis) is the general term for the artificial part itself that replaces the body part usually lost to disease or injury. Prosthetics has a long history, and recent design advances that use battery power and new lightweight composite materials are making prostheses better and easier to use.
No one knows the exact date of when the first prosthetic was made. There has been evidence of two toes belonging to Egyptian Mummies (Berko para. 4). There has also been written evidence that in 500 B.C., a prisoner cut off his foot to escape and his foot was replaced with a wooden foot (Bells para 1). A copper and wooden leg was dug up in 1858 at Capri, Italy and it dates back to 300 B.C (Bells para 1). There has been historical evidence that a general lost his right hand in the Second Punic War, and they made him an iron hand so he could keep fighting (Clements para 5). As you can tell from this evidence, prosthetics were made out of wood, copper, and other metals. They were not nice, but they allowed people just to do everyday things.
I chose the Da Vinci Surgical system as my topic because I am interested into going to physical therapy or into the orthopedics field after undergrad. Surgical equipment is highly important due to the hundreds of accidents that happen and also the high percentage of diseases. As these incidents occur it is important to consider the safety of the patient when it comes to cutting into their bodies. With the invention of the Da Vinci Surgical system it helped with vision and different viewpoints of the patient’s body and also improves precision. It is important to have a machine or tool for more than one type of surgery, one to use on patients with different injuries or diseases. Overall, this surgical system helps improve and help further research how precise and how in control a surgeon can be.

I thought this was a great experience and opened my eyes to all the challenges individuals in wheelchairs have to face. Throughout the day, I noticed I had to go out of my way to find a path that was accessible for a wheelchair. Not only was it inconvenient, but at times it was physically challenging and required a lot of energy. The next day my arms were very sore. It was also difficult to navigate around the classroom, and I sometimes had to ask for assistance to move obstacles out of the way. A lot of the doors on campus were very heavy and made getting through the doorways a lot harder. Most of the time, I needed someone to hold open the door so I could get through to the other room. These experiences made me realize how important is it
The phrase “Nobody is perfect” is appropriately accurate since there are many people who are born without arms, legs, or eventually develop organ failure. Bioengineering helps the people living without or damaged tissues and organs to live a better and comfortable life. Bioengineering will help advance and improve the health of humans by applying biology in engineering. Imagine a world without sick people, or people with deformity. This may be hard to imagine, but with the remarkable inventions and solutions developed and produced by bioengineers, this scenario we can currently only imagine in our heads will hopefully eventually become an ordinary norm. It is crucial to help people who were born with a body that restricts them from doing something everyone else can. They deserve to be able to move and be able to do tasks like every other human being.
Assistive technology plays an important role in the learning process for individuals with disabilities. Assistive technology is defined as "any item, piece of equipment or product system, whether acquired commercially off the shelf, modified, or customized, that is used to increase, maintain, or improve functional capabilities of individuals with disabilities." (Maushak, Kelley & Blodgett, 2001, p. 419) Assistive technology is very beneficial to individuals that have disabilities. For example, students with mental retardation benefit from extremely organized learning situations because of their limited cognitive abilities. Students who are hearing impaired, blind, or visually impaired may need differentiated pedagogical materials. More emphasis should be placed on visual materials for students with hearing impairments than for other students. Modifying instruction for all students, especially exceptional students, requires strong dependence on media, materials and technology and the right choice of these components to fit particular ends. Moreover, research has indicated that technology not only can be adapted for use with students with disabilities, but when used can enhance students' educational achievement and self-image. (Duhaney & Duhaney, 2000, p. 393) With this knowledge, there have been many new products that have been developed to help individualize programs to fit the criteria for specific disabilities. Through out this paper we will be disusing three different pieces of assistive technologies. We will be looking at Dynawrite, AlphaSmart, and Texthelp and the benefits of each program.
Prosthetic limbs, one of the examples of physical enhancement, have improved to such an extent that the capabilities and...
The topic I picked for our community project was traffic lights. In a community, people need stop signs and traffic lights to slow down drivers from going to fast. If there were no traffic lights or stop signs, people’s lives would be in danger from divers going too fast.
