IRCT20250704066369N1 IRCT 2025-07-29 Tehran University of Medical Sciences comparison of the immediate effect of dry needling and active release technique in amateur athlete's posterior thigh muscle shortness Comparison of the immediate effect of dry needling and active release technique in amateur athletes with hamstring muscle shortness 2025-08-10 anticipated 34 Complete https://irct.ir/trial/84635 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Random assignment is performed using the Block Randomization method so that the number of participants in the two groups is balanced. 1. Determine the block size: Given that we have two groups in this study, the block size must be divisible by 2, which is the most common block size when we have two study groups, 4. From each block of 4, 2 people will be placed in Group A or the dry needling group and 2 people in Group B or the active release technique group. 2. All possible combinations for a block: AABB, ABAB, ABBA, BBAA, BABA, BAAB Since we want the total sample size of the study to be 34 people, 9 blocks will be randomly selected from all the permutations. 3. Allocation of individuals to blocks: Each individual who enters the study is entered into the study based on the order of individuals in the selected block. For example, if the random block is AABB, the first two individuals enter group A and the second two individuals enter group B, and ultimately we will have two groups of 17 individuals, Blinding description: Eligible individuals, after being informed about the general treatment method and the purpose of the study, voluntarily fill out and sign the consent form. If they meet the inclusion criteria, they are randomly assigned to one of the treatment groups. Then, the initial characteristics and demographic information of the participants (including age, weight, height, gender, and body mass index) and pre-treatment evaluations are recorded by a trained assessor who is unaware of the study type. After this evaluation, a treatment session will be conducted by a trained therapist. Participants will also be re-evaluated immediately and 24 hours after the treatment by a trained assessor who is unaware of the type of treatment. N/A Hamstring muscle shortness. Intervention 1: Dry needling intervention group: This method is performed using disposable stainless steel needles (mm 0.3*60 DongBang). In this method, subjects are placed on the treatment table in a prone position, with their feet on the bed, and the hamstrings are needled at 3 points, each for 1 minute, using a rapid entry and exit technique in a conical shape. To standardize the approach and optimize the application of dry needling, points are needled approximately close to the movement points of the hamstring muscles. The first two points are at 30 and 60%, respectively, of a straight line drawn from the attachment of the ischial tuberosity to the long and short heads of the biceps femoris muscle and then to the head of the fibula. The third point is at 60% of a straight line extending from the ischial tuberosity (the attachment point of the semimembranosus and semitendinosus muscles) to the medial condyle of the femur. Intervention 2: Active release intervention group: Active release, compared to other manual therapies, is a unique technique in which the patient actively moves, while the therapist uses his or her hands to first palpate, then assess and release the soft tissue. In this method, the therapist encourages the patient to move actively by applying manual pressure to the affected areas, and the muscle is stretched from a short length to a long length. This combination of pressure and active movement helps to increase muscle flexibility. Steps: The patient lies prone on the bed, with the patient's feet hanging over the end of the bed. The therapist then finds the area of the muscle that is most tight by skin contact and palpation and applies gentle pressure to it. The patient bends and straightens their knee to stretch the muscle from its short length to its long length. This cycle is repeated five times. Yes - There is a plan to make this available What will be shared: All relevant data that has been agreed to be published can be shared. When: 6 months after results To whom: It will be accessible to everyone involved in the industry. Conditions: For researchers who are conducting research in this field and need information to improve their studies. Where to obtain: 1.Email 2.Contact Number 3.Postal Address How to obtain: The individual submits their request, and after the necessary checks are made regarding how the data will be used, the individual's job scope, and the necessary documents are provided to the individual.کل Comments:
