Repetitive low-energy shock wave treatment for chronic lateral epicondylitis in tennis players.

چکیده
BACKGROUND There is conflicting evidence regarding extracorporeal shock wave treatment for chronic tennis elbow. HYPOTHESIS Treatment with repetitive low-energy extracorporeal shock wave treatment is superior to repetitive placebo extra-corporeal shock wave treatment. METHODS Seventy-eight patients enrolled in a placebo-controlled trial. All patients were tennis players with recalcitrant MRI-confirmed tennis elbow of at least 12 months' duration. Patients were randomly assigned to receive either active low-energy extracorporeal shock wave treatment given weekly for 3 weeks (treatment group 1) or an identical placebo extracorporeal shock wave treatment (sham group 2). Main outcome measure was pain during resisted wrist extension at 3 months; secondary measures were >50% reduction of pain and the Upper Extremity Function Scale. RESULTS At 3 months, there was a significantly higher improvement in pain during resisted wrist extension in group 1 than in group 2 (mean [SD] improvement, 3.5 [2.0] and 2.0 [1.9]; P =.001 for between-group difference of improvement) and in the Upper Extremity Function Scale (mean [SD] improvement, 23.4 [14.8] and 10.9 [14.9]; P <.001 for between-group difference of improvement). In the treatment group, 65% of patients achieved at least a 50% reduction of pain, compared with 28% of patients in the sham group (P =.001 for between-group difference). CONCLUSION Low-energy extracorporeal shock wave treatment as applied is superior to sham treatment for tennis elbow.

Background: Several treatment options have been proposed to treat lateral epicondylitis. Both Platelet rich plasma (PRP) and Extra-corporeal Shock Wave Therapy (ESWT) are new treatment modalities for tendinopathy. Patients and Methods: Thirty seven patients suffering from chronic lateral epicondylitis (tennis elbow) for at least six months were treated in this study. The patients were divided i...

OBJECTIVE: Lateral epicondylitis is one of the widely seen lesions of the arm characterized by pain localized over lateral epicondyle which is the insertion site of the wrist extensors, and extensor muscles of the forearm. It is easy to diagnose lateral epicondylitis but treatment involves some inherent drawbacks. Conservative management includes non-steroidal anti-inflammatory drugs, ultrasoun...

Lateral epicondylitis, commonly referred to as tennis elbow, affects 1% to 3% of the population.1 It is thought to be an overuse injury, originating in the wrist extensor muscles, rather than an inflammatory problem. It is brought on by occupational activities and sports that involve a repetitive wrist motion or a power grip. The condition is most commonly associated with workrelated activities...
