We processed meta-analysis to test if the effects of laser therapy and mobilization techniques are evidence-based practice for treating tennis elbow. By researching and collecting the results of previous studies on tennis elbow, we inquired into the difference in the effects of each treatment methods on pain, grip strength, and ROM. A total of 10 international and domestic articles on the treatments of tennis elbow were selected for this study, including 7 articles on the effect of laser therapy and 3 on mobilization techniques. According to the qualitative meta-analysis, all 7 of the articles on laser therapy and 1 of the mobilization technique were double-blinded and randomized the subjects, and all of the 10 studies were designed in a high quality research, using statistics. The results of the studies on laser therapy showed in terms of statistical significance: 4 out of 7 did not decrease pain after therapy, and 3 out of 5 did not increase grip strength after therapy. In the studies on the effects of mobilization technique, both the 2 studies significantly increased grip strength after therapy. For other studies which measured ROM and tension, the mobilization therapy increased ROM significantly, and decreased tension significantly. The results of our study are shown in a diverse form in terms of the effects of different therapy techniques. This is related to the accuracy of the measurement tools for assessments and diagnoses. Further qualitative studies on the evidence-based practice and researches on tennis elbow are needed.
