IRCT20151017024572N17 IRCT 2018-07-12 Iran University of Medical Sciences Comparing local injection of ozone, corticosteroid and prolotherapy under ultrasound guidance in the treatment of inflammation of shoulder tendons Comparing ultrasound guided injection of oxygen-ozone vs. corticosteroid vs. prolotherapy in the treatment of shoulder tendinopathy : a randomized, prospective, multicenter randomized clinical trial 2019-05-10 anticipated 45 Complete https://irct.ir/trial/20698 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: A simple random method for randomization will be used and individuals (patients) will form random units. A random sequence will be generated using RAS software. A central randomization method will be used to conceal random allocation. The random sequence will be created by the statistician and will be available to her. The doctor will be connected to the statistician by telephone or text message and will ask him or her about the random allocation of the participant to the specific group, Blinding description: In order to blind the patient, the doctor will prepare the injection material in the syringe, and will cover the syringes with an aluminum sheet to avoid being aware of the type of injection. It should be noted that dilution of corticosteroid and normal salin will be done to equalize the volume of all three injectable solutions. Patients in each group will be evaluated by a physical medicine and rehabilitation specialist, who is not aware of the type of injection, before the injection, two week , two months and six months after the injection. 3 Inflammation of the shoulder tendons. Intervention 1: Intervention group (ozone therapy): 5cc ozone 20μg / L, in subacromial space with lateral aperture under ultrasound guidance. Intervention 2: Intervention group (porlotherapy): 5cc dextrose 20%, in subacromial space with lateral aperture under ultrasound guidance. Intervention 3: Control group (corticosteroid therapy ): 1cc triamcinolone 40mg + 1cc lidocaine , in subacromial space with lateral aperture under ultrasound guidance.
