Phantom Limb Research Paper

“Losing a leg was like having to learn how to suck in air through the pores of my skin. Somehow I survived, but each breath was painful” (Draanen 157). Jessica, from Wendelin Van Draanen’s The Running Dream, loved to run. Which is why when she lost her leg she described it as stated above, like learning how to take in air through her skin. Her leg was a part of her, something she loved to use, and when it was gone she felt off balance, both metaphorically and actually. I felt this way when someone very close to me died. His name was Zackary, or Zack for short, and he was my cat. When he died of a thickened heart wall and a thrombus collapse at the age of 1 and a half, I felt as if I had lost something vital to me. A body part that was necessary

Gawande wrote about a woman named M. who scratched through her skull to her brain in her sleep. The scratching only gave her momentary relief before the urge to scratch just grew bigger making the annoyance worse. Since pain was thought to be so closely linked to itching through nerves, M’s doctors thought that the only way to get rid of the itch was to cut off the function to the nerves where the itch was present. After losing the feeling in her face and after taking anesthetics and antibiotics the urge to scratch still came back, becoming more of a chronic itch. Fueling Gawande's theories about the itch, he theorized that maybe there is nothing wrong with the nerves at all. He thought that there was something going wrong in the brain when it tells your body that you need to scratch, when clearly you do not. After becoming more in depth with M’s case, Gawande then introduced a man named H.. H. suffered from strange symptoms of phantom limbs. Phantom limb sensations were described as, “... far too varied and rich to be explained by the random firings of a bruised nerve” (Gawande, 2008). Gawande's theory expanded by theorizing that the brain can't visually see that the person/self is healed when the nerve transmissions are shut off due to

When a body part is lost the corresponding part of the brain is not able to handle the loss and rewires its circuitry to make up for the signals it was no longer receiving from the missing digit. The rewiring might occur in one of two ways. Perhaps nerve impulses in the sensory cortex begin to course down previously untraveled pathways. The second theory is that neighboring neurons in the cortex may actually invade the territory left fallow because sensations are no longer received from the missing limb.

Kathy, a 20-year-old woman, awakens one morning to a tingling, numb sensation covering both of her feet. This has happened to her a number of times throughout the year. In the past, when experiencing this sensation, within a couple of days to a week the numbness would subside, and so she is not too concerned. About a week later, she

Cases of ‘phantom limbs’, ‘disappearing phantom limbs’ and ‘positional phantoms’ are a well-written about phenomena. Dr. Sacks describes how sensory messages can be sent to the phantom limbs, causing a neurological condition.

The author starts off by recalling his personal experiences with phantom limbs. A young boy had a phantom limb phenomenon. The term phantom limb was first used by Silas Weir Mitchell in 1872. Phantom limb seems to occur because of the images created by the images of the body and makes the person always believe that it is all there even after an amputation. The body is basically trying to make sense of the amputation. It is not actually caused by incorrect neural activity. It is actually more built from the part of the brain that creates the mental image of the body. Turns out on 90 percent of amputee actually have a phantom limb experience. Researchers have tried to treat phantom limb with the mirrors and Virtual Reality.

The phantom limb pain the woman is experiencing is described as a painful condition of the amputated limb after the stump has completely healed. It is a chronic pain that occurs in more than 80% of amputees especially those who suffered pain in the limb before the amputation. Theories suggest that phantom limb pain results from redevelopment or hyperactivity of cut peripheral nerves, scar tissue or neuroma formation in the cut peripheral nerves, spinal cord deafferentation, and alterations in the thalamus and cortex. More so, the CNS integration, which involves reorganization and plastic modifications of the somatosensory cortex, effects the receptors in perceiving the pain of the amputated limb despite of the limb itself being absent. In addition,

What does it feel like to have a missing/paralyzed limb? I'm sure this question has popped into many of our heads at one point in time. You would think that the sensations and feelings from that limb would disappear altogether. However, for some people, they can still feel the presence of their limb even after it is gone. There is no clear answer as to why this happens, but one thing is for certain. A large percentage of people with phantom limbs will sometimes feel pain from that missing limb. There is nothing happening to the individual physically that would cause them to feel pain from their phantom limb. What is actually happening is that the nerves that are located at the area of amputation (the "stump") are sending signals to the brain, which tricks the brain into believing that the missing limb is still there. It is hypothesized that the brain may also interpret these signals as pain. I found this to be an interesting topic, as it gives a good example as to how our brains and nervous systems work when interpreting changes in the body.

Phantom Limb Pain (PLP) is a serious condition that occurs when a person who has lost a part of their body though amputation, trauma (brachial plexus), or loss of nervous connections in an appendage, perceives that the limb is still there and experiences sensations coming from this area. It was first described in 1866 by S. Weir Mitchell, an American neurologist, through a short story published in Atlantic Monthly. While Mitchell may then have wondered if this was specific to wounded Civil War soldiers, it has since been established as quite common (1). Over 70% of amputees report phantom limb pain for years after amputation (2). Several theories have been proposed regarding PLP, although there is still much to be

The earliest hypothesis regarding the cause of phantom limbs and pain was that of neuromas. These were thought to be nodules comprised of remaining nerves located at the end of the stump. These neuromas presumably continued to generate impulses that traveled up the spinal cord to portions of the thalamus and somatosensory domains of the cortex. As a result, treatment involved cutting the nerves just above the neuroma in an attempt to interrupt signaling at each somatosensory level (5). This and other related theories were deemed unsatisfactory because of the fact the phantom pain always returned, indicating that there was a more complex reason.

Prosthetic limbs have been around for centuries, but what is one thing they all have in common? They have all been a nuisance. In recent years technology of the modern day Prosthesis has ventured to new heights, but they have not perfected an artificial limb yet. With the amount of people in need of prosthetic limbs, the demand for a perfect prosthesis is tremendous. The perfect prosthesis shouldn’t feel or even look like an artificial limb. Prosthetics should go unnoticed throughout the rest of the amputee’s life.

Sacks discussed the ideas behind the phantom limb and how they affected many peoples live. The most interesting story was about a sailor that accidentally cut off his index finger. For forty years he thought he would poke himself in the eye whenever he moved his hand to his face. One day he lost the feeling in his entire hand including his phantom finger and his problem was cured (Sacks 66-67). Up to 70 percent of amputees confirmed that they still feel or still thought a missing limb was there. They often feel that they can reach out and grab something. Some won't sleep in a certain way because they feel the missing limb between them and the mattress. The sensations felt stem from the activity of the sensory axons

An extensive matrix of neurons in the brain gives us the sense of our own bodies and body parts. Pain results when this matrix produces an abnormal pattern of activity, as a result of memories, emotions, expectations or signals from various brain centres and not just from signals from peripheral nerves. Because of the lack of sensory stimulation or a person’s efforts to move a nonexistent limb, abnormal patterns may arise, resulting in phantom pain.

to the area of prosthetics because of the lack of money they would get from it. However,

Phantom limb pain is a painful sensation experienced in a body part which is no longer part of the body, often due to amputation.(3) Individuals also reported that tingling as well as various types of pain have occurred, and these sensations may eventually disappear or may persist as cramping, shooting, burning or crushing
