“…Although both peripheral (Sherman et al, 1989;Arena et al, 1990;Katz, 1992a) and central (Katz and Melzack, 1990;Melzack, 1990Melzack, , 1995 mechanisms have been implicated in the development of phantom limb pain, no conclusive evidence about causal mechanisms has been found. A number of authors (Merzenich et al, 1984;Calford and Tweedale, 1988;Garraghty and Kaas, 1991;Pons et al, 1991;Kaas, 1995) have reported massive reorganization of primary somatosensory cortex subsequent to amputation of individual digits or dorsal rhizotomy in monkeys and other species.…”

Effects of Regional Anesthesia on Phantom Limb Pain Are Mirrored in Changes in Cortical Reorganization

The causes underlying phantom limb pain are still unknown. Recent studies on the consequences of nervous system damage in animals and humans reported substantial reorganization of primary somatosensory cortex subsequent to amputation, and one study showed that cortical reorganization is positively correlated with phantom limb pain. This paper examined the hypothesis of a functional relationship between cortical reorganization and phantom limb pain. Neuroelectric source imaging was used to determine changes in cortical reorganization in somatosensory cortex after anesthesia of an amputation stump produced by brachial plexus blockade in six phantom limb pain patients and four pain-free amputees. Three of six phantom limb subjects experienced a virtual elimination of current phantom pain attributable to anesthesia (mean change: 3.8 on an 11-point scale; Z ϭ Ϫ1.83; p Ͻ 0.05) that was mirrored by a very rapid elimination of cortical reorganization in somatosensory cortex (change ϭ 19.8 mm; t (2) ϭ 5.60; p Ͻ 0.05). Cortical reorganization remained unchanged (mean change ϭ 1.6 mm) in three phantom limb pain amputees whose pain was not reduced by brachial plexus blockade and in the phantom painfree amputation controls. These findings suggest that cortical reorganization and phantom limb pain might have a causal relationship. Methods designed to alter cortical reorganization should be examined for their efficacy in the treatment of phantom limb pain.

“…51 There is also evidence shown by Arena JG, et al and Affleck G, et al that dysphoric mood states directly exacerbate pain intensity in various other chronic pain syndromes. 52,53 In a study, Moseley found that when 'training the brain' in CRPS 1 patients, it is important to activate the premotor followed by the primary motor networks, to reduce pain. 54 Significant symptom reduction was observed in a small group of 12 male patients through regular performance of 'virtual', followed by imagined, and then mirror movements.…”

“…This participant was placed within the control group (VR only) and uses prosthesis. Interestingly the participant noted that it took some time for him to believe that it was himself (1)(2)(3)(4)(5)(6)(7) from baseline through to the 2 nd follow up session for participant RNOH2. RNOH2's proprioceptive drift error (Fig.5) does generally suggest a decrease (linear R 2 = 0.03253) despite an approx.…”

“…Not only does this affect the individual's mental wellbeing (coping with the psychological trauma associated with the limb loss) but also their physical state (imposed by the chronic pain effects) and the rehabilitation outcome [4]. Regional rehabilitation units, Defence Medical Rehabilitation Centres and NHS rehabilitation centres are posed with diverse challenges as the individual experiences emotional discomfort in addition to psychological trauma, reduced mobility and Phantom Limb Pain [5].…”

Abstract-Advances associated in terms of cost and quality in virtual reality have brought new paradigms to help with rehabilitation in a vast range of areas. Previous systems have focused on visual based only paradigms with varied results. The system described in this paper draw not only from visual based approaches but also adding elements of haptics to increase the level of immersion but in combination also invoke the sense of agency in patients with phantom limb pain. This paper presents three case studies of an on-going clinical study. The initial results suggest an increased sense of embodiment of the virtual limb promotes a decrease in perceived levels of pain. The results strengthen the view that the cortical map does not fully "disappear" yet lays dormant.
