IRCT20180728040618N6 IRCT 2023-02-01 Iran University of Medical Sciences The effect of dry needling on hamstring muscles stiffnss and strength of hamstring muscles The effect of dry needling on hamstring muscles stiffnss and isometric strength of hamstring muscles using an isokinetic dynamometer 2023-04-21 anticipated 20 Complete https://irct.ir/trial/66276 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Other, Randomization description: Random allocation will be done by the method of variable blocks, which includes blocks of 4 letters and is made of letters A and B. Then, the random treatment list, which will be obtained at the end of the randomization task, will be placed in the form of letters A and B inside sealed and numbered envelopes (the letter A represents dry needling and the letter B represents dry needling placebo). The process of random allocation will be done by a person outside the research team and before the start of the study. After the initial evaluation of the person by the examiner, numbered envelopes, corresponding to the sequential number of each person included in the study, will be given to him.Finally, after each patient enters the therapy sessions, the therapist will adjust the therapeutic interventions based on the letters inside the envelope. Also, it should be mentioned that after placing people in the desired group, they are asked not to share their grouping information with the examiner in order to prevent data contamination, Blinding description: The evaluation and treatment stages will be performed by two different physiotherapists and the evaluator will be impartial to the interventions to avoid bias. Individuals in the dry needle placebo group will receive a placebo and will be unaware of their grouping. N/A Adaptive hamstring shortening. Intervention 1: Intervention group: dry needling; This technique is performed by a physiotherapist who has an official certificate of dry needling courses from the Iranian Physiotherapy Association. The Deep dry needling method is performed using disposable stainless steel needles (0.3 x 60 mm; SMC, Seoul, Korea). People are placed on the treatment bed lying on their stomachs with their feet outside the edge of the bed. The hamstring muscles are needled in 4 places, each for 1 minute, with the fast in-out cone-shape technique, and then the needles remain in place for 20 minutes as recommended by Hong. People receive dry needling for 4 sessions. Two of the sites are in the long and short heads of the biceps femoris muscle at a point of 30% and 60% of a straight line from the ischial tuberosity to the fibular head. For Tendinous Tendinous and Membranous Tendon muscles, the dry needling site was selected at two points at 30% and 60% of a straight line from the ischial tuberosity to the medial epicondyle of the femur. Intervention 2: Control group: dry needling placebo; The dry needling placebo method is similar to the original method, that is, all the steps, including how to position the person, how to perform the technique, and cleaning the desired area, are fully implemented, but the needle is inserted subcutaneously and does not enter deeper tissues. Then it remains in place for 20 minutes. Yes - There is a plan to make this available What will be shared: Deidentified individual participant data collected for the primary and secondary outcome measures will be shared if necessary. When: Starting 6 months after publication To whom: The data will be available for physical therapists working in academic institutions and also clinicians working in the field of musculoskeletal disorders Conditions: The raw data and results of this study can be used in future relevant systematic reviews. Thus, the raw data and results of this study will be available for researchers working in the field of dry needling. Where to obtain: Applicants can contact the researcher of this study zahrasadat mirkhalili by email. Email address: zahra.mirkhalili@gmail.com How to obtain: Applicants should explain in detail about their project and how the data/documents of this study will be used in their project. Then, the data/documents files will be sent by email to applicants on request. This process may takes 10-12 working days. Comments:
