To assess the effect of personalized quantum sonotherapy on the level of pain of patients taken to orthopedic surgery under regional anesthesia through pain score visual analoge score (VAS). VAS ranges from 0 to 10 being 0 no pain an 10 the worst pain ever felted. It would be measured before and after placing de sonotherapy, 24 and 48 hour after surgery.

To assess the effect of personalized quantum sonotherapy on the level of anxiety of patients taken to orthopedic surgery under regional anesthesia through anxiety score Questionnaire of anxious state STAI (Spielberger). STAI is a score to meausre anxiety, it has 20 questions each one with a possible value from 0 to 3 points.
