Abstract
Background: Epicondylopathia humeri radialis is often diagnosed by general practitioners. Usually, the therapy comprises transcutaneous electrical nerve stimulation and the application of a forearm brace. Manual therapy is prescribed beyond transcutaneous electrical nerve stimulation and forearm brace, and it is performed by specialized physiotherapists. However, data comparing the effectiveness of all methods are scarce. In this study, the therapeutic effects of manual therapy were compared to those of transcutaneous electrical nerve stimulation and forearm brace along with a combination of all three. Methods: Fifty-two patients diagnosed with epicondylopathia humeri radialis by a general practitioner were randomized into three treatment arms: 19 patients received a combination of manual therapy, transcutaneous nerve stimulation, and forearm brace; 18 patients received manual therapy only; and 15 patients wore a forearm brace and received transcutaneous nerve stimulation. The primary outcomes included the range of motion and pain intensity. The secondary outcomes were elbow function and psychological well-being. Primary and secondary outcomes were measured before treatment (0), and 4- and 8-weeks post-treatment using the Patient Rated Tennis Elbow Evaluation Questionnaire and the Short Form Health Survey Questionnaire. Results: The range of motion and pain intensity did not differ between the intervention groups.Conclusions: Manual therapy alone is as effective as combination therapy with transcutaneous nerve stimulation and the use of a forearm brace for epicondylopathia humeri radialis. Hence, there is evidence supporting the inclusion of manual therapy in the guidelines for treating patients with epicondylopathia humeri radialis.
