20180000681 · 2018-01-04 ·

A system and method for treating neural lesions is disclosed. The inventive method comprises determining the location of a neural lesion in a patient and applying a selected modality to a dermatomal region on the patient to compensate for the existence of the neural lesion. The selected modality includes the implementation of a method or device to activate any number of receptors located in the skin of the patient. The modality implemented in the correct dermatomal region initiates a somatosensory signal to the brain which responds with a corresponding motor signal to the affected area. Proper implementation of the selected modality supports neuroplasticity and neurogenesis to create a permanent solution to overcome the neural lesion.
