Clinical Trial Summary

Lateral epicondylitis (LE) or tennis elbow; is the most common cause of lateral pain in the elbow, with an incidence of 1-3% in the general population. It is thought to develop as a result of overuse inflammation of the wrist joint extensor tendons, originating from the lateral epicondyle of the humerus. The most common symptom is the pain located in the lateral aspect of the elbow, which can spread across the forearm extensor face and is aggravated by wrist extension, forearm supination, and strong grip movements of the hand. The diagnosis is made by clinical and ultrasonographic evaluations. Significant correlations were found between clinical symptoms of LE and increased joint extensor tendon thickness, focal hypoechogenicity, intratendinous calcification, bone abnormality, and diffuse heterogeneity findings that can be monitored by diagnostic ultrasound. Wait-see policy, conservative treatment regimens, local injections, and surgical approaches are the treatment methods that can be used on a patient-based basis until today. Conservative treatment options include physical therapy modalities such as exercise, massage, laser, electrotherapy, therapeutic ultrasound, extracorporeal shock wave therapy, the use of various splints, ice application, activity modification, rest, NSAIDs, and taping methods. The two prominent bracing methods are the lateral epicondylitis band and the wrist extension splint. Although these two methods are frequently used in daily practice, the limitations of studies investigating the effectiveness of orthoses and which orthosis are more effective draw attention. In comparative studies, some factors may affect clinical results such as allowing patients to use NSAIDs when necessary and organizing a home exercise program. Besides, none of them included a control group and the patients were not evaluated by ultrasonography. This study aims to compare the effects of the use of two different splints (lateral epicondylitis band and wrist extension splint) on clinical and ultrasonographic parameters in patients with a diagnosis of lateral epicondylitis.

Clinical Trial Description

The study is randomized and controlled. 158 patients will be included in to study who apply to Dokuz Eylül University Faculty of Medicine, Department of Physical Medicine and Rehabilitation Clinic with the complaint of elbow pain, aged between 18-65 years and diagnosed with lateral epicondylitis by clinical and ultrasonographic methods. These patients will be divided into three groups randomly (group1 n:53, group 2 n:53, group 3 n:52). First group: A lateral epicondylitis bandage will be given to the patient for 6 weeks. The bandage will be positioned 5 cm distal to the lateral epicondyle to allow for elbow flexion. After the application, patients will be asked to punch and the belt on the band will be tightened. After the patients are asked to open the fist, the suitability of the pressure applied to the forearm will be evaluated. Patients will also be asked to repeat this application while wearing the band. Second group: A wrist extension splint will be given to the patient for 6 weeks. The splint will be used to keep the wrist at 15-20 degrees of extension and to wrap the distal wrist and forearm without hindering finger movements. Third group: These patients will be monitored with a wait-and-see policy. No splint or band will be given to the patient. Before treatment, age, gender, occupation, body mass index, duration of symptoms, trauma history, dominant hand, side of the symptom and previous similar complaint history will be questioned in all three groups. All of the patients will be asked not to lift heavy for 6 weeks, to use their splints throughout the day, and to remove them during bathing and sleeping. Throughout the study, all patients will be allowed to take only paracetamol oral tablets as pain relief if needed and will be asked to keep a medication diary. All patients will be evaluated 3 times, before the treatment, in the 3rd week during the treatment process, and in the 6th week after the treatment with a visual analog scale, patient-rated tennis elbow evaluation questionnaire, hand dynamometer, and ultrasonographic measurements. All evaluations will be done blindly by the clinician. The primary aim of this randomized controlled single-blind study is to compare the effects of lateral epicondylitis bandage and wrist extension splint treatment on ultrasonographic changes in patients with lateral epicondylitis. Ultrasonographic evaluations will include measurement of maximum tendon thickness and assessment of hypoechogenicity, heterogeneity, neovascularity, and bone abnormality. The maximum tendon thickness in the capitellar and radiocapitellar regions of the common extensor tendon will be measured for both upper extremities. The secondary aim is to compare the effects of these two different splint treatments on clinical changes such as pain, functional disability, sensitivity, and handgrip strength. Pain and functional disability will be measured by the Visual Analog Scale and Patient Rated Tennis Elbow Evaluation questionnaire, the sensitivity will be measured by algometer, and handgrip strength will be measured by hydraulic hand dynamometer for both hands. ;
