title: Computer use associated with poor long-term prognosis of conservatively managed lateral epicondylalgia.
abstract: METHODS
  Multicenter prospective design with a cohort of patients with lateral epicondylalgia commencing physical therapy.
  
  
  OBJECTIVE
  To identify key factors associated with long-term prognosis of conservatively managed lateral epicondylalgia.
  
  
  BACKGROUND
  The response to conservative management of lateral epicondylalgia is inconsistent and the rate of recovery varies widely among individuals. The reasons for these discrepancies are not understood. The identification of factors associated with prognosis will aid in the prediction of patient outcomes.
  
  
  METHODS
  Sixty patients with lateral epicondylalgia, recruited from 9 sports medicine clinics and 2 hospital outpatient physical therapy departments in Ontario, Canada, were followed for 6 months. A baseline clinical assessment was conducted on each participant using standard physical therapy techniques. The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and a 100-mm pain visual analog scale (VAS) were completed at baseline and 6 months later.
  
  
  RESULTS
  The key factor associated with both 6-month DASH and pain VAS scores was repetitive-work tasks (DASH, 9.8 [P < .011; pain VAS, 13.1 mm [P = .0105]). A subanalysis indicated that women were more likely than men to have cervical joint signs and, among women, positive cervical articular signs were also associated with higher final DASH and pain VAS scores.
  
  
  CONCLUSIONS
  Although many of the participants identified sports activities as the cause of their injury, these findings emphasize the importance that a patient's work tasks can have on recovery of lateral epicondylalgia. This would suggest that management should perhaps focus on work stations, postures, and behaviors.
