Multiple factors including site of amputation or presence of preamputation pain have been found to have a positive correlation with the development of phantom limb pain. The paradigms of proposed mechanisms have shifted over the past years from the psychogenic theory to peripheral and central neural changes involving cortical reorganization.
What causes phantom limb pain in amputees?
Risk factors. Residual limb pain. People who have persistent pain in the remaining part of the limb usually have phantom pain, too. Residual limb pain can be caused by an abnormal growth on damaged nerve endings (neuroma) that often results in painful nerve activity.

What is the best treatment for phantom limb pain?
What is phantom pain and why does it occur?
The main cause of phantom pain is still unknown. However, some experts tend to believe that phantom pain is psychological.

Phantom pain does eventually go away with time. Many people find their pain has decreased by about 75 percent or more within two years after amputation surgery. If it does return, talk to your doctor. There may be an underlying problem — such as a neuroma (nerve overgrowth) — triggering the sensation.
Can stress cause phantom limbs?
Seventy-four per cent of subjects demonstrated some significant stress-pain relationship. The results lend support to the psychological theory underlying the use of psychophysiological interventions such as biofeedback and relaxation therapy in amputees with phantom limb pain.
Who is at risk of phantom limb pain?
Higher prevalence rates of PLP have been reported in people with lower limb amputations than in those with upper limb amputations [4, 11]. Lower limb(s) amputations are performed chiefly to treat complications of diabetes, and may be associated with risk factors for PLP such as pre-amputation pain and depression [12].
Where is phantom limb pain most common?
PLP is often described as tingling, throbbing, sharp, pins/needles in the limb that is no longer there. It occurs more commonly in upper extremity amputations than lower extremities and tends to be intermittent in frequency. Pain severity varies, and onset can be immediate or years afterward.

Is phantom limb pain rare?
More recently, approximately 60%–80% of amputees experience phantom limb sensations. The incidence of phantom limb pain has varied from 2% in earlier records to higher rates today.
Why do people have phantom pain?
Because the risk of developing phantom pain is higher for people who have experienced pain in the limb before amputation, some doctors recommend regional anesthesia (spinal or epidural) in the hours or days leading up to amputation. This may reduce pain immediately following surgery and reduce the risk of lasting phantom limb pain.
What is Phantom Pain?

What happens to the brain after an amputation?
Studies also show that after an amputation the brain may remap that part of the body's sensory circuitry to another part of the body. In other words, because the amputated area is no longer able to receive sensory information, the information is referred elsewhere — from a missing hand to a still-present cheek, for example.
What happens when you touch your cheek?
Because this is yet another version of tangled sensory wires, the result can be pain.

Most people who've had a limb removed report that it sometimes feels as if the amputated limb is still there. This painless phenomenon, known as phantom limb sensation, isn't the same as phantom pain.
Where does phantom pain come from?
"Makin and co-workers have directly challenged the notion that phantom pain as a consequence of limb amputation derives from reorganization of body parts that are represented in the somatosensory cortex [a mental map of body parts ]," neuroscientist Elena Nava of the University of Hamburg, who was not involved in the study, told LiveScience.
What part of the brain is affected by phantom pain?
In addition, the phantom pain was linked to disrupted activity between different parts of the sensorimotor cortex, the part of the brain that processes touch and movement.
Is pain remapping correlated with pain?
The problem, Makin said, is the study shows that pain and remapping are correlated, but does not show that one causes the other.
Do amputees with phantom pain have the same brain activity as people with both hands?
The scans showed that amputees with phantom pain had the same pattern of brain activity as individuals with both hands. This was a huge surprise, Makin said. "If we take an individual who suffers from phantom pain, his brain would be indistinguishable from your brain."
What is phantom limb pain?
Phantom-limb pain is a common sequela of amputation, occurring in up to 80% of people who undergo the procedure . It must be differentiated from non-painful phantom phenomena, residual-limb pain, and non-painful residual-limb phenomena.
What are the determinants of phantom limb pain?
Central changes seem to be a major determinant of phantom-limb pain; however, peripheral and psychological factors may contribute to it. A comprehensive model of phantom-limb pain is presented that assigns major roles to pain occurring before the amputation and to central as well as peripheral changes related to it.

What is phantom limb pain?
Phantom limb pain is a complex condition that causes pain or discomfort in a limb or body part that no longer exists. For many years, scientists and researchers believed phantom limb pain was psychological, but a number of research studies have indicated the pain sensations from this condition originate in the spinal cord and brain. Nevertheless, the cause of phantom limb pain is generally unclear—the most common theory is nerves misfiring pain signals to the brain.

What is phantom limb pain?
The concept of phantom limb pain (PLP) as being the pain perceived by the region of the body no longer present was first described by Ambrose Pare, a sixteenth century French military surgeon [1]. Silas Weir Mitchell, a famous Civil War surgeon in the nineteenth century, coined the term “phantom limb pain” and provided a comprehensive description of this condition [2]. It continues to remain a poorly understood and difficult to treat medical condition. A recent study estimated that there were about 1.6 million people with limb loss in the USA in 2005 and this number was projected to increase by more than double to 3.6 million by the year 2050 [3]. Vascular problems, trauma, cancer, and congenital limb deficiency are among the common causes of limb loss. The number of traumatic amputations has also increased since the beginning of conflict in Iraq and Afghanistan [4]. The incidence of PLP has been reported to range from 42.2 to 78.8% in patients requiring amputation [5–8].

What is Phantom Limb Pain?
Phantom limb pain is pain in an area where there has been an amputation. The pain can be minor and go away on its own with the symptoms decreasing over time. However, phantom limb pain can be extremely debilitating and can lead to chronic pain.
What Causes Phantom Limb Pain?
The underlying root cause of phantom limb pain is not clear, but it originates in the spinal cord and brain. This is believed to be caused by a mixed signal in the brain. After amputation occurs, areas of the spinal cord and brain miss input sensations from where the limb should be. The body takes time to adjust.
Treatment Options
Treatment options vary depending on the severity of the pain sensations. Like many pain conditions, a combination of multiple treatment options is most effective in reducing pain. It can be difficult to treat phantom limb pain, but your doctor may begin with medication options and noninvasive treatments.
