The missing limb often feels shorter and may feel as if it is in a distorted and painful position.
Current Treatments for Phantom Limb Pain Mirror therapy and virtual reality are two noninvasive and inexpensive treatments that hold promise in the management of phantom limb pain.
For many of these individuals, pain from their injuries does not cease following amputation; many suffer from phantom limb pain PLPor pain that is perceived in an area of the body that no longer exists. There are numerous theories behind the mechanisms of PLP and many treatment options.
Tsao and his colleagues at Walter Reed Army Medical Center recently published a review article describing the various theories and therapies associated Phantom limb PLP. Tsao to gain additional insight into recent developments regarding research in PLP.
Pathophysiology of PLP Phantom limb pain can occur in many regions of the body, but limbs are the most common sites. Naturally, PLP is of stronger intensity than phantom sensations. There are also kinetic sensations, which are the perceptions of movement, and kinesthetic components, which describe size, shape, and position of the missing limb.
Attempts also have been made to characterize PLP,3,4 but the pathophysiology and etiology are unclear. Several theories Phantom limb been proposed to describe the origins of PLP, including cortical reorganization, body schema, and neuromatrix theory see Weeks et al for a review.
Proprioceptive memory refers to memory of specific limb positions.
For many people with single- and multiple-limb amputations, pain does not cease following amputation. Article covers current treatments. A phantom limb is the sensation that an amputated or missing limb is still attached. Approximately 60 to 80% of individuals with an amputation experience phantom sensations in their amputated limb, and the majority of the sensations are painful. Phantom sensations may also occur after the removal of body parts other than the . Phantom Limb (real name: Hamilton G. Fantamos) is a supervillain with invisible arms and legs. Phantom Limb was born Hamilton G. Fantamos and came from a long line of adventurers like his grandfather, Fantômas, who among others such as Lloyd Venture, Eugen Sandow, Oscar Wilde, Aleister Crowley First appearance: "Tag Sale - You're It!".
Tsao and his colleagues proposed that proprioceptive memories remain in an individual even after a limb has been amputated. Individuals are typically busy with activities during the day, so the experience of PLP is more pronounced when they are sitting quietly at home at night. Individual experiences range greatly, especially among patients at Walter Reed.
Some patients feel volitional control over their phantom, and some feel that the limb is fixed in a specific position. The authors described a particular patient who felt he was pulling the trigger on his rifle but unable to move his hand to a different position.
With the range of unique individual experiences, finding a single effective treatment option presents a significant challenge to PLP researchers. Most pharmacologic therapies have not met with success. Transcutaneous electrical nerve stimulation TENS is a promising nonpharmacologic treatment that involves brief, intense stimulations at trigger points or along the peripheral nerve of the residual limb.
In this treatment, patients view the reflection of their intact limb moving in a mirror placed parasagitally between the arms or legs.
Patients simultaneously move the phantom limb in a manner similar to what they are observing. As a neurologist in the US Navy, Dr.
Tsao became interested in mirror therapy after observing the increase in the number of amputees from Iraq during At about that time, Congress had appropriated funds for research on medical conditions affecting amputees.
Tsao decided to approach the head of the rehabilitation department to discuss conducting a controlled trial to investigate the use of mirror therapy to treat PLP, because up to that time there had been no controlled trials to determine its efficacy.
Tsao and his colleagues decided that the best way to evaluate the efficacy of mirror therapy was to break it into three separate components: Participants viewed the virtual image in the mirror and repeated movements eg, toe flexion and extension, rotation about the ankle, foot flexion with their phantom limb.
Pain scores were measured using a mm visual analogue scale VAS. Changes in scores on the VAS were significant: Phantom limb pain and related disorders. Prevalence and characteristics of chronic phantom limb pain among American veterans: Am J Phys Med.

S. Ramachandran, Center for Brain. After you have part of your arm or leg amputated, there’s a chance you could feel pain in the limb that’s no longer there. This is known as phantom limb pain.
For many people with single- and multiple-limb amputations, pain does not cease following amputation. Article covers current treatments. Nov 19, · A phantom limb is a vivid perception that a limb that has been removed or amputated is still present in the body and performing its normal functions.5/5(1).
A phantom limb is the sensation that an amputated or missing limb is still attached. Approximately 60 to 80% of individuals with an amputation experience phantom sensations in their amputated limb, and the majority of the sensations are painful.
