Given the importance of muscle function of the shoulder joint, along the existing boom of the new techniques in the specific muscle activation has been carried out an experimental study using a "Test Neuro Propioceptive Response" with other scientific techniques (EMG, Borg Scale and ROM), wich will provide us information about the activation of the upper trapezius, acromial, scapular, spine, latissimus dorsi. This study has five professional volunteered women specialist of Physical Activity, wich to analyze them, their muscle activation. The results show that all the muscles analyzed shows significant improvement (p<.05) in mean muscle activation recorded with electromiography in the dominant arm, after activation with muscle activation technique employed. These results, although with such a small sample denote the analytical techniques that improve muscle activation.
