IRCT20180711040419N3 IRCT 2025-10-11 Shiraz University of Medical Sciences Investigating the effect of kinesiotaping on jump height and agility Investigating the effect of faciliatory kinesiotaping technique on latent trigger points of the Quadriceps and Gastrocnemius muscles on jump height and agility in Volleyball and Basketball players: A randomized clinical trial study 2025-10-07 anticipated 44 Complete https://irct.ir/trial/85803 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: For randomization and allocation of participants into the intervention and control groups, block randomization with 11 blocks, each consisting of 4 participants, will be used. Accordingly, 44 eligible volunteers will be randomly selected from the study population. Using the Random Allocation Software, which generates a random sequence of groups A and B, participants will be assigned to either the intervention or control group. Group A will be labeled as the facilitation kinesio taping group and Group B as the sham kinesio taping group. Participants will be allocated to one of the two groups in the order of their enrollment, based on the generated randomization list, Blinding description: The study participants will not be aware of whether they are assigned to the intervention or control group, since kinesiotaping is applied to the same muscles in both groups and the participants are not informed about the technique or the purpose of the kinesiotaping application. In addition, the assessor will also be blinded to the group allocation of the participants. N/A Presence of latent trigger points. Intervention 1: Intervention group: Before the application of kinesio tape, participants are asked to shave the hair on the anterior thigh and posterior calf to avoid any interference with the application and effectiveness of the tape. In addition, prior to taping, the skin is thoroughly cleaned with alcohol and then dried. Throughout the study, kinesio tape of the brand Ares, Extreme model, 5 cm width, manufactured in South Korea is used. For the Intervention group, facilitation kinesio taping is applied to the latent trigger points of the quadriceps and gastrocnemius muscles of both lower limbs. The muscle containing the latent trigger point is placed in its lengthened position, and an 8 cm facilitation kinesio tape is applied over the trigger point. Specifically, 2 cm above the point the tape is applied without tension, then with 50% tension directly over the trigger point, and finally 2 cm below the point without tension. Quadriceps muscle – application of facilitation kinesio taping on the latent trigger point: The participant lies in a supine position on the bed, with the leg hanging off the edge so that the muscle is in its lengthened position. Facilitation kinesio tape with 50% tension is applied in the direction of the muscle fibers, from origin to insertion, over the latent trigger point. The edges of each tape strip are rounded before application. Gastrocnemius muscle – application of facilitation kinesio taping on the latent trigger point: For taping the gastro-soleus muscle, the participant lies in the prone position on the bed, with the foot extending off the edge. Then, by performing dorsiflexion to place the muscle in its lengthened position, facilitation kinesio tape with 50% tension is applied in the direction of the muscle fibers, from origin to insertion, over the latent trigger point. The edges of each tape strip are rounded before application. The kinesiotape is applied once for each participant and remains on the tissue for 24 hours. Intervention 2: Control group: Before the application of kinesio tape, participants are asked to shave the hair on the anterior thigh and posterior calf to avoid any interference with the application and effectiveness of the tape. In addition, prior to taping, the skin is thoroughly cleaned with alcohol and then dried. Throughout the study, kinesio tape of the brand Ares, Extreme model, 5 cm width, manufactured in South Korea is used. For the Control group, Sham kinesio taping is applied to the latent trigger points of the quadriceps and gastrocnemius muscles of both lower limbs. The kinesio tape is cut to a length equal to one-third of the circumference of the patient’s thigh or calf at the trigger point site. For the sham group, after identifying the trigger point, the tape is applied without any tension, while the muscle remains in its neutral length, placed horizontally and perpendicular to the muscle fibers. First, the center of the tape is adhered, followed by the edges (61, 77, 78). The kinesio tape remains in place for 24 hours, after which the athlete returns for tape removal and reassessment. Quadriceps muscle – application of sham kinesio taping on the latent trigger point: For this purpose, an I-shaped kinesio tape strip is used. The participant sits on the bed; after removing the backing paper, the tape is applied horizontally over the latent trigger point of the quadriceps muscle without any tension. The center of the tape is adhered first, followed by the edges. The corners of each strip are rounded before application (61, 77).Gastrocnemius muscle – application of sham kinesio taping on the latent trigger point: The participant lies in a prone position with the foot in neutral. An I-shaped kinesio tape strip is applied horizontally, without tension, over the latent trigger point of the gastrocnemius muscle. First, the center of the tape is adhered, followed by both ends. The corners of each strip are rounded before application (77, 88).The kinesiotape is applied once for each participant and remains on the tissue for 24 hours.
