IRCT20190416043289N1 IRCT 2020-01-11 Semnan University of Medical Sciences Study on the effect of dry needling and Mobilization on the Pain of the lateral part of the elbow Study on the effect of extensor muscles dry needling of the wrist with Mulligan mobilization technique on the thickness of extensor carpi radialis brevis tendon, pain and upper extremity function in patients with lateral elbow epicondylitis 2020-01-21 anticipated 34 Complete https://irct.ir/trial/42610 interventional Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: simple and single randomization, The random numbers table such that each person is given a code. The numbers will written in a table, and we select one place from the table in a blinded manner, then we select 17 numbers smaller than the selected number in the same row. The same would be true for the control group. N/A Tennis elbow. Intervention 1: Intervention group: Dry needling with Mulligan Mobilization that the patient in the supine or sitting position, forearm in mid-position, and the 25 * 0.25 mm sterile needle inserted in the trigger points of lateral epicondyle of the elbow with 3 to 4 rotations for 10 minutes. in addition to dry needling, the mulligan technique will be performed with a 5–10-sec gentle glide in extension of elbow and pronation of the forearm. simultaneously taping will apply to maintain normal radius alignment at the extensor muscle group. This technique will be done in 3 sets of 10 repetitions. Intervention 2: Control group:Dry needling that the patient in the supine or sitting position, forearm in mid-position, and the 25 * 0.25 mm sterile needle inserted in the trigger points of lateral epicondyle of the elbow with 3 to 4 rotations for 10 minutes.
