IRCT20201031049207N4 IRCT 2020-12-25 None Shockwave Therapy in Tennis Elbow SWT Effects of Extra Corporeal Shock Wave Therapy versus Ultrasonic Therapy and deep friction message in the management of Lateral Epicondylitis. 2020-12-15 anticipated 74 Complete https://irct.ir/trial/52749 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Patients will be divided into two groups. In Group A (Experimental group) patients will have shock wave treatment and in patients Group B (Experimental group) will have ultrasonic therapy and deep friction massage using coin toss method and allocation sequence will be concealed through sealed envelopes. Concealment of allocation: will be achieved with sequentially numbered, opaque, sealed, envelopes (SNOSE). SNOSE will be used according to guidelines of Doig and Simpson (25). An independent researcher with no clinical involvement in the trial will make the concealed envelopes. 60 Envelopes will be prepared. Half envelops will contain folded papers with Treatment A written on them and the remaining half will contain folded papers with Treatment B written on them. A carbon paper will be inserted in each envelop with carbon side facing the paper so the allocation sequence, patient name, date of birth of participant and other information can be transferred onto allocation paper inside the envelope. A piece of tin foil is also inserted into envelop so the treatment card cannot be read against light. Envelops will be sealed and signed by the maker. A unique randomized number will be allocated to these envelops and shuffled vigorously. Then the envelops will be arranged sequentially and handed over to another independent researcher. Assessor will pretest the participant and if eligible envelope will be allocated to subject. Therapist will record the information on the envelope and open it afterwards to maintain the concealment. Assessor will record the post treatment findings and another independent analyst will analyze the data. This allocation of concealment will ensure the unpredictability of treatment allocation by investigators and patients, Blinding description: In these patients assessor will be blinded to allocation of treatment groups in this study. Patient will be blinded to treatment allocation as treatment will be given in separate rooms for each group. Therapist who is not blinded will not take the outcome measurements. N/A Lateral Epicondylitis or Tennis Elbow. Intervention 1: Intervention group: Group-A shock wave therapy group will be administered shockwave therapy with decompression on lateral side of elbow, with frequency 1Hz, energy level 2.0, for 7 sessions with gap of 4 days in each session. Intervention 2: Intervention group: Group-B Ultrasonic therapy and deep friction massage group. patients will be provided with ultrasonic therapy 2.5w/sec2 (intermittent) 3 times a week for four weeks. deep friction massage will be an adjunct to ultrasonic therapy.
