Phantom pain is a painful perception that an individual experiences relating to a limb or an organ that is not physically part of the body, ...
In phantom limb, the sensation is present in an amputated or absent limb, while dysesthesia refers to discomfort or pain in a tissue that has not been removed or amputated. The dysesthetic tissue may also not be part of a limb, but part of the body, such as the abdomen.
Phantom limb pain is a type of tactile hallucination because it creates a sensation of excruciating pain in a limb that has been amputated. [11] In 1996, VS Ramachandran conducted a research on several amputees to pinpoint the neural reasons behind these illusionary pains.
[1] therapy used for the treatment of phantom limb pain and analysis of limb telescoping. In this image, the mirror helps to represent the patient's perception of their body. Limb telescoping is the progressive shortening of a phantom limb as the cortical regions are reorganized following an amputation. During this reorganization, proximal ...
Phantom pain is pain felt in a part of the body that has been amputated, or from which the brain no longer receives signals. It is a type of neuropathic pain. [20] The prevalence of phantom pain in upper limb amputees is nearly 82%, and in lower limb amputees is 54%. [20]
An occupational therapy assistant using mirror therapy to address phantom pain. Mirror therapy (MT) or mirror visual feedback (MVF) is a therapy for pain or disability that affects one side of the patient more than the other side. It was invented by Vilayanur S. Ramachandran to treat post-amputation patients who had phantom limb pain (PLP ...
No randomized study in medical literature has studied the response with amputation of patients who have failed the above-mentioned therapies and who continue to be in pain. Nonetheless, on average, about half of the patients will have resolution of their pain, while half will develop phantom limb pain and/or pain at the amputation site.
Phantom pain and non-painful phantom sensations result from changes in the central nervous system due to denervation of a body part. [6] [7] Phantom eye pain is considerably less common than phantom limb pain. The prevalence of phantom pain after limb amputation ranged from 50% to 78%. The prevalence of phantom eye pain, in contrast, is about 30%.
