PurposeThe objective of this study was to evaluate the effectiveness of mobilization with movement and kinesiotherapy in the treatment of patients with lateral epicondylosis.MethodsThis cases series included eight volunteers who had chronic lateral epicondylosis. The patients were treated with stretching, massage deep transverse at the lateral epicondyle and mobilization with movement associated with eccentric exercise. The mobilization with movement that consisted of a force of lateral glide of the proximal forearm. We performed twelve sessions, twice a week for 45 min/session. All patients underwent an evaluation with a visual analog scale and functional assessment through questionnaires patient-rated tennis elbow evaluation (PRTEE) and disabilities of the arm, shoulder and hand (DASH), before and after the treatment. Data were analyzed by student’s t test (p < 0.05).ResultsThe results showed statistical differences in pain symptoms before and after treatment, in the analysis and functional assessment through both questionnaires comparing the pre and post treatment.ConclusionThe data obtained in this study demonstrates improvement of the function and pain status of the sample investigated.
