It is characterized by weakness and pain in the muscles and tendons of the forearm responsible for the extension of your wrist and fingers. Trigger point dry needling is a technique reported to be beneficial in managing pain and dysfunction after LE diagnosis. LE is also commonly treated with conservative treatment, such as joint and soft tissue mobilization, self-care home programs, and anti-inflammatory use. We explored a different dry needling approach consisting of in situ dry needling with electric stimulation combined with targeted therapeutic exercise to treat LE in 3 cases.</p><p><strong>Case presentation: </strong>Three patients were referred for dry needling once a week for 6 weeks and home-based exercise therapy for LE.

The patients had reduced pain as measured by a visual analog scale, increased function as measured by the Patient-Rated Tennis Elbow Evaluation Test, and increased grip strength over 6 weeks.</p><p><strong>Conclusions: </strong>This case series illustrates the use of dry needling and a home exercise program to provide a favorable outcome in a patient with LE. Patients had an 80% to 100% reduction in pain and similar improvements in function that were significantly beyond the minimum clinically important difference. This dry needling approach is a safe and effective treatment of LE in the short term.</p>","PeriodicalId":50041,"journal":{"name":"Journal of Sport Rehabilitation","volume":" ","pages":"301-306"},"PeriodicalIF":1.7,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140295153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
