IRCT20220410054479N1 IRCT 2022-08-14 Esfahan University of Medical Sciences Investigating effects of extracorporeal shockwave therapy on hamstring tightness and comparing it with dynamic soft tissue mobilization in basketball players Investigating effects of extracorporeal shockwave therapy on hamstring tightness and comparing it with dynamic soft tissue mobilization in basketball players aged 15 to 18 years old 2022-06-05 anticipated 40 Complete https://irct.ir/trial/63462 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Due to the fact that patients are added to the study over time and not all cases are available at the same time, in order to perform randomization, each eligible patient is assigned to one of the two groups by lottery, Blinding description: Due to the difference in intervention in each of the two groups, the investigator are aware of the type of intervention in each group. But the participant, the outcome assessor, and the Data analyser will not have any knowledge of the type of intervention in each group. 2 Hamstring muscle tightness. Intervention 1: The first intervention group: In this group, participants will undergo dynamic soft tissue mobilization by an experienced physiotherapist for 4 weeks, three sessions per week. In this group, the patient will take a prone sleeping position, the therapist will be placed on the side of the desired muscle, and the following actions will be performed in sequence. Longitudinal strokes will be applied to the entire hamstring muscle to determine the specific point of muscle titans. Once the desired point is determined, the rest of the treatment will be limited to this point. The patient will then shift to a supine position and will flex the hip and knee 90 degrees. Deep longitudinal strokes will be applied from the distal to the proximal in the direction of the titans point while the foot will be passively extended. Subsequently the progressive and dynamic technique will be performed. In this technique, the patient will actively extend the leg to activate deep muscle inhibition. In the final stage, the hamstring muscle must be contracted eccentrically by the therapist's hand, despite the resistance created. At this stage, the muscle is stretched to the end of the range of motion. During this movement, 5 deep blows are applied from the distal to the proximal on the tight point. Intervention 2: The second intervention group: In this group, participants will undergo extracorporeal shock wave (ESWT) on hamstring muscles in prone position for 4 weeks, one session per week. The ESWT device is the DUOLITH SD1 model made by STORZ MEDICAL AG. A total of 2,000 impulses will be delivered to the hamstring muscles by the radial head. Of the mentioned impulses, 1,000, 500, and 500 impulses will be for the long head of the biceps femoris, the semitendinosus muscle, and the semimembranosus muscle, respectively. All impulses will enter the middle of these muscles. The repetition frequency of the shock wave will be 15 Hz.
