IRCT20171030037093N9 IRCT 2019-05-06 Esfahan University of Medical Sciences Evaluation of the effect of shockwave therapy on pain of patient with post stroke hemiplegic shoulder pain The effect of shockwave therapy on pain of patient with post stroke hemiplegic shoulder pain 2019-06-01 anticipated 40 Complete https://irct.ir/trial/39179 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Diagnostic, Randomization description: Patients are randomly assigned to one of the two groups by selecting the cards named A and B, Blinding description: In this study, the principal executor is considered to be medical doctors who are fully aware of the goals of the study and the types of treatments. Patients will not be aware of statistical research goals and how to compare treatments. However, they are fully aware of the fact that they are treated with different treatments in one of the two groups and that they receive treatment for their illness and have been studying satisfactorily. Patients will not be aware of shock or vision shock therapy. The counselor for statistics and information analytics, about treatment (shockwave and shock sham) and the name of the patients is not known. 2-3 Shoulder pain. Intervention 1: Intervention group: Under treatment with shockwave, the number of sessions is 5 sessions, which consists of 3 sessions of focus with intervals and 5 radial sessions with intervals of two days per week. The SHAKEVIEW protocol is in this form. Shockwave focus is expressed as the number of shocks of 1,000 at any point with a J2 / 0-3 / 0 energy of ZH 4 and a radial to 1000 shocks per point with an energy of 1.33 j3 and a frequency of 15Hz. Intervention 2: Control group: Sham treatment was used with zero energy. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is I will decide untill finishing the study
