ABSTRACT The number of lower limb amputees is growing worldwide. Trauma, particularly vehicle accidents, and vascular-related diseases are the two major causes. Lower limb amputees use prosthesis for mobility during daily activities (Ma, 2015). A high percentage of amputees are not comfortable using their prosthetics and some cause infections. SocketComforter is designed to eliminate discomfort, adjust pressure in specific locations in the prosthetic, and optimize efficiency. BACKGROUND INFORMATION Prosthetic patients usually suffer from discomfort while wearing their assigned prosthetics due to high pressure on the limb and swelling in the tissues of the residual limb. A prosthetic socket is the top part of the artificial limb that attaches …show more content…
After the patient is eligible to take part in this experiment, the experimentee is introduced to the FitSocket. As shown in Figure 1, “the FitSocket is a robotic socket measurement device that directly measures tissue properties. With this data, rapid-prototype testing of sockets and socket molds are performed in order to make rigid, spatially variable stiffness, and spatially/temporally variable stiffness sockets (Petron, n.d.).” Figure 1: FitSocket Model The patient undergoes the testing with FitSocket three times to ensure the accuracy of the data provided. An in-depth analysis of the results is done in a lab to locate the softest and stiffest tissues in the residual limb. CES Material Selector will be used to find the finest and most comfortable material to use as the socket for the amputee. The Material for the SocketComforter will be: 1) Flexible to suit the softness and hardness of tissues in the residual limb. 2) Adjustable pressure ranges to decrease and increase pressure when needed by the patient. 3) Waterproof to maintain a good hygiene. 4) Lightweight and high durability for easy use and attachment. 5) Soft to comfort the patient while using the
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).
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 1985 the movie going community was enthralled with its newest hit movie titled Short Circuit. The movie portrayed a robot that due to accidental electrocution believed that it was alive. In the final scenes the robot know as Johnny five was seen removing one of its damaged robotic arms and replacing it with a new and identical arm. This idea of replacing one limb with another of equal function was unfortunately only movie fiction. This fiction however is quickly becoming a reality for countless thousands of people living with prosthetic limbs. In the October 1998 issue of Scientific American the story of Melissa Del Pozzo a thirteen year old girl living with a prosthetic limb gives an example of the hope many are living with. Her only dream is that she could one day tickle the ivories of her piano again. Her hope could soon be rewarded. With continued research, prosthesis's are making advancements that were once only dreams. These advancements are seeing the most change in the areas of dexterous movement, feeling, and comfort.
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.
The materials in prosthetic limbs have always evolved along side technology, usually changing for the better. Prior to the development of electronics and plastics,

Finally, I recommend that the group looks further into the different interfaces and materials that prosthetics can be used combined with in order to erase the control issue that come with prosthetics.
The most common use of biomechanics is in the development of prosthetic limbs used for the handicapped. Most work on prosthetics is done in laboratories where scientists use calibrated machines to test stress and wear of artificial limbs. These days, prosthetics, are made of titanium and lightweight fiberglass to make a near perfect match with most people. The most common prosthesis is the replacement in a below the knee amputation. The American Society of Biomechanics (ASB) held a meeting at Clemson University of 1997 in order to develop a sports prosthesis that would stand up to every day flexing of the knee for performance in sports.
The main topic of this essay will be about the in-depth research into medical prosthetics

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
The idea of having an amputated limb and being able to receive a prosthetic limb within a few short hours is still a dream in today’s world. Scientists and researchers have made huge leaps and bounds in recent years, but prosthetic limbs have been around for decades. The oldest ever found was in Cairo, Egypt in the year 2000. It was a prosthetic toe made of leather and wood from 3000 years ago (Clements, 2008). This limb showed us that for the most part prosthetics have not changed a whole lot, but how they are made has improved. Prosthetic limbs can now be designed by using CAD/CAM, computer aided design and manufacturing. They can speed up the process it takes to make the limbs for patients. Clinical use of this process is still slow to get going in a lot of states and the world. The most important part of the prosthetic limb to the patient is not whether the limbs functionality is better, but the comfort of the socket. The socket is where the residual limb will reside in the actual prosthetic limb. When the handmade casts are used, it is hard to make a socket that will work well for the patient because it is hard to make an exact replica of the limb. That is why more funding needs to go to places that will teach people how to use the CAD/CAM design process and to help companies buy the expensive fabrication sites to actually make the limbs. Not only is the use of CAD/CAM a better process, but it is faster and will get the patients a better fitting limb that they will want to use more often.
Over the years scientists have noted many complaints of a strange form of pain called phantom limb pain. This pain is strange because it is located in an appendage that no longer exists. By many of the amputees the pain is described as totally unbearable. Phantom limb pain has even driven some victims crazy. For the amputee population this is a very real problem that definitely needs to be solved.
Amputation is the general term describing a condition of disability resulting from the deliberate surgical removal of a part of the body, a limb, or part of a limb (Bowker & Michael, 1992). Limb loss can be a congenital condition, the result of traumatic injury, or a surgical procedure to treat disease (Clawson, 2009). Clawson posits that the majority of amputations in the United States are the result of vascular disease caused by diabetes (p. 393). In cases of traumatic amputation, adjustment and adaptation is more difficult than for people who have had time to prepare, such as may occur with diabetes. Amputations may be performed at any level in the upper extremities such as the digits, the hand, or the arm, or in the lower extremities such as the toes, the foot, or the leg. Amputation is an emotional, life-altering occurrence that most often results from either disease or trauma (Hanley et al., 2004). Appropriate rehabilitation is a vital element to helping people with lower limb amputation learn to walk and function again and live high quality lives.
