title: Comparison of two ultrasonographic localization techniques for the treatment of lateral epicondylitis with extracorporeal shock wave therapy: a randomized study.
abstract: OBJECTIVE
  To describe and compare two ultrasonographic localization techniques for the treatment of lateral epicondylitis with extracorporeal shock wave therapy (ESWT).
  
  
  METHODS
  Forty-one subjects selected through clinical examination were randomly assigned to two groups of treatment.
  
  
  METHODS
  Each subject received a three-session ultrasound-guided ESWT (performed weekly). Lateral tangential focusing was used in group A, whereas back tangential focusing was used for group B.
  
  
  METHODS
  Total Elbow Scoring System (TESS) and a visual analogue scale (VAS) were used to evaluate each subject before the treatment and at six months follow-up.
  
  
  RESULTS
  TESS and VAS pretreatment scores were homogeneous between the groups (p > 0.05). In both groups there was a significant (p < 0.05) increase in the TESS score and a decrease in the VAS score but there was no resolution of the pain. TESS and VAS follow-up scores were homogeneous between the two groups (p > 0.05).
  
  
  CONCLUSIONS
  There was no difference between the two techniques of using ESWT.
