Lateral cord stimulation (LCS) was discovered by the author as the producer of an average threshold increase for abnormal muscle contraction responses, in experimental pathological conditions, as described and referred. This physiological effect is proposed to improve tone, motor function and speech, in patients with spasticity of different causes, such as cerebrovascular accident, congenital brain malformations, perinatal anoxia (image called cerebral palsy), sequels of neurosurgery, etc. Due to its non-invasiveness and possible efficacy, the use of magnetic stimulation is proposed to try to demonstrate its therapeutic utility. This is the clinical test of phase 2/3 of the method, in the future, and how its use could be extended, if the results were positive, its indications could be extended to other pathological conditions, giving a greater spectrum of spastic patients, potentially benefited
