Efficacy of extracorporeal shock wave in the treatment of lateral epicondylitis in athletes using ultrasonography

A randomized, double-blind randomized clinical trial with a sham group with a sample size of 25 patients.

Study Location: Sports Medicine Federation Step 1: Clinical examination Step 2: Complete the informed consent form Step 3: Complete the questionnaire including personal details Step 4: Perform ultrasonography Step 5: Complete the Visual Analogue Scale and Disabilities of the Arm, Shoulder, and Hand Questionnaire, strength hand grip Measurement Step 6: Implementation of the treatment.Two groups studied (exprimental, sham),double blind study (the evaluator and the investigator are not aware and only the operator knows the status of the groups). Step 7: Assess the effect of treatment.

inclusion criteria: Confirmation of lateral epicondylitis, at least 3 months of pain in the area, treatment of the affected area for up to 3 months,visual analogue Scale greater than 4. exclusion criteria: Age less than 18 years old, Contraindication of shock wave, history of lateral epicondial surgery, elbow deformity, cervical radiculopathy , History of rheumatologic diseases, history of shock wave treatment in 12 months Past or injection in the last 3 months.

An experimental group: a 4 Hz frequency shock wave, an energy flux density of 0.08 j/mm ², 2000 Shock, once a week for 3 weeks The Sham group: a 4 Hz frequency shock wave, and energy flux density of 0.04 J /mm ², 1500 Shock, once a week for 3 weeks with foam in the area. Physical therapy is then performed with stretching exercise, 3 times a day and 4-5 repetitions.

Visual Analogue Scale Score, Disabilities of the Arm, Shoulder, and Hand Questionnaire Score, strength hand grip score, Check the thickness of the muscle.

Simple randomization by lottery means that at the beginning of the study and in the first referring patient, the group names are written in 2 pieces of paper and placed in one of two intervention or control groups by the patient operator's removal. By identifying the first patient's treatment group, the next patient will be assigned to the other group and thus the patients will be divided into groups. In this study, the researcher, evaluator, and participants are unaware of the study group allocation and only the operator is aware of the group assignment.

Participants enter the research after completing the informed consent form and are divided into two groups. From this stage, only the operator of the device has been informed from the medical group and the participants, the resarcher and the evaluator to avoid the bias in the study from the subjects of the study groups No information is available.
