L'objectif de cette étude est de montrer que la stimulation du canal proprioceptif au moyen de vibrations, en réactivant certaines séquences sensitivomotrices corticales, pourrait permettre d'améliorer la mobilité et la douleur des patients porteurs de syndrome douloureux régional complexe. Une des anomalies observée est une désorganisation des structures responsables de la commande et de l'organisation du mouvement, aboutissant à une incongruence entre les afférences sensitivosensorielles et les efférences motrices.

Le syndrome douloureux régional complexe de type I (SDRCI) n'est plus considéré aujourd'hui comme une pathologie du système nerveux périphérique mais bien comme une pathologie du système nerveux central à expression périphérique. Cross-over designs or simulated vibratory stimulation should be used to minimize bias. Prospective randomized studies in larger numbers of patients are needed. Vibratory stimulation may significantly improve range of motion and pain in patients with CRPS-I, probably by reestablishing consonance between sensory input and motor output at cortical level. A significant decrease in analgesic use occurred in the intervention group. During each session, patients in the intervention group ( n = 7) received vibratory stimulation of the affected region the remaining 4 patients served as the controls.Īfter 10 weeks, range-of-motion gains were about 30% larger and pain severity was about 50% lower in the intervention group than in the control group. Conventional rehabilitation sessions were given for 10 weeks. The goal of the present study was to determine whether vibratory stimulation by improving proprioceptive feedback may increase range of motion and minimize pain in patients with CRPS-I.Īn open non-randomized study was conducted in 11 patients with CRPS-I of the hand and wrist. According to previous studies in the field of motor control, one efficient way to correct this mismatch could be a proprioceptive feedback enhancement. CRPS-I may result from a mismatch between sensory input and motor output leading to a disorganization of motor programming in cortical structures. Other anecdotal therapies include spinal blocks, spinal cord stimulation, and local injection of botulinum toxin.Ĭomplex regional pain syndrome type I (CRPS-I) is now considered as a central nervous system disease with peripheral manifestations. Treatment is often unsatisfactory and many drugs commonly used for neuropathic pain have been reported anecdotally to help (e.g., gabapentin). It has been suggested that a peripheral lesion causes aberrant input leading to “central reorganization,” probably at the level of the spinal cord, and that the latter is responsible for the pain and movement. Identical toe movements may occur without pain, referred to as: “painless legs–moving toes,” and a similar condition affects the upper limbs: “painful arms–moving fingers.” The pathophysiology of PLMT and its variants is not known but most reports suggest an association with a peripheral lesion, usually at the level of the root or nerve, though in many cases no cause is found. The syndrome may be unilateral or bilateral. It is the pain which usually brings the patient to medical attention. The syndrome of painful legs–moving toes (PLMT) is an adult-onset, rare disorder characterized by pain, typically of a neuropathic quality, in the feet or legs, associated with writhing movements of one or more toes. Further clinical trials are needed to investigate these new methods of muscle pain relief. The results suggest that both cutaneous and muscle sensory feedback reduce muscle pain, most likely via segmental and supraspinal processes. The strongest analgesic effects of the vibration-induced muscle inputs occurred when illusory movements were perceived (−38%, p=0.01). Concurrently stimulating both sensory channels induced stronger analgesic effects (−51%, p<0.01), as shown by the lower levels of electrodermal activity.

In addition, tangential skin vibration reduced pain intensity by 33% ( p<0.01), primarily by activating cutaneous receptors. Muscle tendon vibration, which primarily activated muscle receptors, reduced pain intensity by 30% ( p<0.01). Secondly, pain alleviation was compared in subjects in whom muscle tendon vibration evoked kinesthetic illusions of the ankle joint. We first aimed at comparing the analgesic effects of mechanical vibration applied to either cutaneous or muscle receptors of the TA or to both types simultaneously. In the present study, muscle pain was induced experimentally in healthy subjects by administrating hypertonic saline injections into the tibialis anterior (TA) muscle.
