Chapter 1 INTRODUCTION 1.1 Feedback Control of a Prosthetic Elbow Joint: Amputation is taken from the Latin terminology ‘amputare’ meaning to cut out .It is basically a removal of a limb due to medical reasons such as diseases, accidents etc . After this an artificial device (Prosthetics) is provided to fulfill all the desirable needs. Prosthesis is an artificial device that replaces a missing body part which may be lost due any traumatic accidents or medical reasons. In the 19th Century hooks and wooden limbs were used as replacement to fulfill the supporting needs to overcome support as well as the psychological effects experienced during time . Prosthetic Arm is a biomedical device consisting of levers, links, and joints in an open or closed system, which is also a combination of electronics. Thus a need for a specified prosthetic which would help in fulfilling the requirements of the patient . Prosthetics also come under different categories with respect to the patient’s demand and desirable need. 1.1.1 Cosmetics Prosthesis: This type of Prosthesis mainly deals with the physical appearance rather than the functional aspect. It is satisfied with skin color of patient. Figure 1.1.1: Cosmetic Prosthesis 1.1.2 Body …show more content…
These designs vary depending upon the intended use of the hand. A variety of different actuation methods have been used. Previous robotic arm designs have focused on the mechanical issues of the construction and operation of the prosthesis. Most prostheses are controlled using methods that are not intuitive, such as using the contraction of muscles of the opposite arm. No project has been identified that investigates the feedback control of prostheses from the body’s neural network, which is a more natural control. This project attempts to lay the foundation for an arm that can mimic the human arm, with an intuitive method of

Igor Spetic is a volunteer at the research center in the Louis Stokes Cleveland Veterans Affairs Medical Center. He uses his left hand, which is his own flesh and blood, and his right hand, a plastic metal prosthetic (a consequence of an industrial accident). The prosthetic in his right hand uses the “myoelectric” device which is controlled by flexing his muscles in his right arm. Myoelectric prosthetics serves the purpose of an artificial limb while maintaining the appearance of the limb. Myoelectric prosthetics are different from body-powered prosthetics because body-powered prosthetics uses cables and harnesses strapped to the individual to mechanically and carefully guide the artificial limb through muscle, shoulder, and arm movements.
Dr. Lee Hello I am Arturo Haces- Garcia I am an 11th grade student at Santa Gertrudis Academy High School, in Kingsville, Texas, and I am interested in developing a project for my local science fair, this project involves using electromyography signals to control servos. The project in question is a Prosthetic forearm, which will move by connecting small muscle electrodes to certain muscles in the face, where certain actions, like blinking, smirking, and frowning will make the arm do a certain moves.
CHARCOT FOOT VS TRANSTIBIAL AMPUTATION A transtibial amputation, also known as a bellow knee amputation is one of the most frequently performed amputations. Amputation is a choice for diseased limbs, severe injury to lower limbs for which attempts at salvage can be lengthy, emotionally and financially costly. Transtibial amputations may be performed for the following reasons: -Trauma -Tumors -Infections -Peripheral Vascular Diseases This assignment is based on Amputation vs Charcot foot.
A company named Braingate has developed a combination of hardware and software to directly sense the neuronal signals in the brain which controls limb movement. This device, with the size of a baby aspirin, when implanted in the brain records the neuronal signals and sends those to a computer, which then converts the signal to digital instruction and performs actions like moving a cursor. In 2006 the first clinical trial was performed on a 25 year old quadriplegic paralyzed person named Matthew Nagle. The trial became a grand success when after some practice Nagle could move and click a computer cursor and even make a robotic arm pick up small things.

Evolution - the gradual adapting and changing process that humans go through. Looking back from the past, now in the present, and into the future it is easy to see the we as humans have always and always will feel the need to adapt to our surrounding in order to survive. It is apart of what makes us human. In Juan Enriquez presentation over “What humans will look like in the next 100 year,” he explains this need for advancement through the use of prosthetics; saying that to some people they are a need, but with certain advancements they are becoming more of a want. The human race feels the push to advance in order to survive thus pushing us to view prosthetics as a way to change fundamental aspects of humanity.
A “regular” amputation would look like the limb getting cut off quickly in a circular motion to stop more blood loss, though blood loss was one of the least common ways of dying. One of the most dangerous parts of an amputation was that it wasn’t very sanitary. The surgeons and doctors would use unsanitary and reused bandages which is why Bromine became an important part of operations, cleaning the instruments and such. The whole of the United States and the future of the world learned from the diseases and injuries from the Civil War.
Following an amputation weight acceptance, single limb support and advancement are essential to achieve a typical gait pattern. Due to the amputation the patient will have a decrease in body weight, which will cause a shift of the center of mass over the base of support. The purpose of the study was to evaluate traditional prosthetic training (TPT) compared to that of propioceptive neuromuscular facilitation (PNF) methods on gait biomechanics and weight bearing. The study included all male subjects that were all traumatic amputees and in the prosthetic phase of rehabilitation for their first prosthesis. The subjects were randomly assigned into groups receiving PNF and TPT prosthetic training.
Robot-assisted therapy is being used more frequently in various aspects of therapy. Robot-assisted therapy is the use of robotic devices that have been tailored in assisting various specific sensorimotor functions. Robot-assisted therapy uses the various robotic equipment only for short amount of times during therapy sessions. The purpose of the robotics is not to replace what used to happen by muscle movement as assistive devices, but instead to help the person regain their independent movement without the use of the robotics (Mehrholz, Hädrich, Platz, Kugler & Pohl, 2012). Robot-assisted therapy is used mostly with patients who have had a stroke that left them with partial, reduced or no arm function.
Amanda Kitts is a great example “The assembly is topped by a white plastic cup midway up Kitts’s biceps, encircling a stump that is almost all that remains from the arm she lost in a car accident in 2006.” Due to the car accident in 2006, Kitt has an arm with “… flesh-colored plastic…underneath are three motors, a metal frame, and a network of sophisticated electronics.” Although, Kevin wasn’t in a car accident he still uses bionic parts for his legs and arms. “…little Freak showed up one day with these shiny braces strapped to his crooked legs, metal tubes right up to his hips, why those were even more cool than crutches.” This quote directly from “Freak the Mighty” (pg. 12) proves that Freak has similar problems.
Instrumental activity of daily living (IADLS) that affected are driving and community mobility, meal preparation and care of others may also be affected. Rest and sleep may also be affected if the client is in pain and their limited mobility keeps them from become comfortable enough for sleep. Education, work, play, leisure, as well as social participation will be affected by the prosthetic (AOTA,
Frankenstein brought the monster to life by sending electricity through certain points of the body. He learned that by doing this he might restore life to a body he had created. Scientists today are trying to create functional prosthetic limbs. Doctors and scientists have discovered a couple of ways to do this. One way to do this is place electrodes on remaining muscle near the amputation site.
The knee joint is one of the strongest and most important joints in the human body. It allows the lower leg to move relative to the thigh while supporting the body’s weight (Taylor, n.d.) as knee joint is one of the major weights bearing joint in the body. Knee joint plays an important role in our daily lives such as walking, running, sitting and standing. It allows physiological movement such as flexion and extension.
