Preliminary Evidence for Training-Induced Changes of Morphology and Phantom Limb Pain
The aim of this study was to investigate whether a special prosthetic training in phantom limb pain patients aimed at increasing the functional use of the prosthesis leads to neural morphological plasticity of brain structures and a reduction in phantom limb pain. For chronic pain disorders, it was shown that morphological alterations due to pain might become at least partially reversed by pain...
متن کاملPhantom limbs and neural plasticity.
The study of phantom limbs has received tremendous impetus from recent studies linking changes in cortical topography with perceptual experience. Systematic psychophysical testing and functional imaging studies on patients with phantom limbs provide 2 unique opportunities. First, they allow us to demonstrate neural plasticity in the adult human brain. Second, by tracking perceptual changes (suc...
متن کاملCharacterising phantom limb phenomena in upper limb amputees.
A systematic descriptive survey was carried out on a clinic population with acquired upper limb amputation in which clear distinctions were made between phantom experiences, pre-amputation pain and stump pain. It was found that of 76 participants 96% reported phantom experiences and 84% were currently experiencing phantom limb phenomena (PLP). Sixty-nine percent (69%) of those currently experie...
متن کاملInduced sensorimotor brain plasticity controls pain in phantom limb patients
The cause of pain in a phantom limb after partial or complete deafferentation is an important problem. A popular but increasingly controversial theory is that it results from maladaptive reorganization of the sensorimotor cortex, suggesting that experimental induction of further reorganization should affect the pain, especially if it results in functional restoration. Here we use a brain-machin...
متن کاملThe perception of phantom limbs. The D. O. Hebb lecture.
Almost everyone who has a limb amputated will experience a phantom limb--the vivid impression that the limb is not only still present, but in some cases, painful. There is now a wealth of empirical evidence demonstrating changes in cortical topography in primates following deafferentation or amputation, and this review will attempt to relate these in a systematic way to the clinical phenomenolo...
