Neuromotor therapy is one of the treatments of choice to modulate spasticity following stroke. However, its decadasbenefits are limited in some subjects, so associating this therapy with others could bring greater benefits. One therapeutic option is Yan, the electrotherapy according to Hufschmidt, which is based on low- afrequency rhythmic electrical stimulation to provoke muscle estudiocontraction. The aim of this study was to determine the effects of limitadaneuromuscular electrotherapy associated with neuromotor therapy estimulaci & oacute;n,versus neuromotor therapy on muscle mass, functionality and t & eacute;cnicasspasticity of the paretic upper limb after stroke. Prospective experimental study composed of 2 groups: Neuromotor therapy evaluacion,vs. neuromotor therapy associated with electrotherapy (CON vs cl & iacute;nicoENM, respectively n=5 each).At baseline and end, muscle thickness (ultrasound), strength test (dynamometer) and functionality (Action Research Arm Test) were evaluated. Spasticity (Tardieu Scale) was considerandoevaluated during the days of intervention. Chronic ischemic stroke ywas the most prevalent among the groups. An increase in paretic labiceps brachii muscle thickness was observed from 2.89 +/- 0.53 to la3.03 +/- 0.62 cm in the CON group and from 3.27 +/- 0.89 to 3.48 +/- 0.83 cm in the ENS group (time effect p <0.05; eta(2 )= 0.386), with no differences between groups. In relation to the variable's strength ejemploand spasticity of flexor and extensor muscles of the paretic arm, muestraand lean mass of the whole body and by body segments, no significant differences were observed between the groups and no futuro changes were observed after the intervention (p >0.05). In both delgroups there was an increase in the thickness of the biceps brachii rehabilitadormuscle on the paretic side after the intervention. No significant resultados differences were observed between groups in strength, spasticity, whole body lean mass and by body segments.
