Abstract
INTRODUCTION: Lesions of peripheral nerves cause loss of motor and sensory function and also lead to hyperreflexia and hyperalgesia. Activity-dependent therapies promote axonal regeneration and functional recovery and may improve sensory-motor coordination and restoration of adequate circuitry at the spinal level. METHODS: We compared the effects of passive (bicycle) and active (treadmill) exercise on nerve regeneration and modulation of the spinal H reflex after transection and repair of the rat sciatic nerve. Animals were evaluated during 2 months using electrophysiological, functional, and histological methods. RESULTS: Moderate exercise for 1 hour/day, either active treadmill walking or passive cycling, improved muscle reinnervation, increased the number of regenerated axons in the distal nerve, and reduced the increased excitability of spinal reflexes after nerve lesion. DISCUSSION: Maintenance of denervated muscle activity and afferent input, by active or passive exercise, may increase trophic factor release to act on regenerating axons and to modulate central neuronal plasticity.

En tant que version électronique du classique esthésiomètre à filaments de Von Frey, la dernière évolution de l’instrument électronique Von Frey de Bioseb, conçu pour déterminer le seuil de sensibilité mécanique chez les rongeurs (rats et souris) par stimulation sous la patte, est un outil indispensable pour vos recherches sur l’hyperalgésie et l’allodynie. En mesurant et en enregistrant la force à laquelle l’animal présente un réflexe de retrait de la patte, il est possible d’étudier les pathologies liées à la réponse sensorielle ainsi qu’à l’hyper- ou l’hypoesthésie.
L'EVF5 intègre une caméra embarquée au niveau de la zone de stimulation et fonctionne avec un nouveau logiciel dédié révolutionnaire
