IRCT20240513061781N1 IRCT 2024-11-18 Razi University Investigating the effect of TDCS on knee proprioception, balance, muscle EMG, movement function and reaction time speed, after neuromuscular fatigue. Comparison of the effects of transcranial direct current stimulation (M1 and DLPFC) on knee joint proprioception, balance, muscles activity, movement function and reaction time speed, after neuromuscular fatigue in female amateur athletes. 2024-12-21 anticipated 45 Complete https://irct.ir/trial/79016 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Prevention, Randomization description: Subjects will be randomly assigned to one of the experimental or control groups based on the output of the random number generator software by a person not involved in the research. The sequentially numbered opaque sealed envelope (SNOSE) method will hide the allocation, Blinding description: Subjects and outcome assessors will not be aware of the assigned group. The random assignment of subjects to groups is done by a person not involved in the research, and the assigned group for each subject is placed in a sealed envelope and will be available to the laboratory expert. After evaluating the results of the study before the test, each subject will be provided with the envelope related to the person applying the stimuli, in this way, neither the subject nor the evaluator will be informed of the type of intervention. 3 Controlling the effect of fatigue on factors such as balance, proprioception, electrical activity of the muscles acting on the knee and movement performance. Intervention 1: The first Intervention group: receiving tDCS stimulation of the M1 point, with a current intensity of 2 mA for 20 minutes in each session with a number of 5 sessions. Intervention 2: The second Intervention group: Intervention group: receiving tDCS stimulation of the DLPFC point, with a current intensity of 2 mA for 20 minutes in each session with a number of 5 sessions. Intervention 3: Control group: Sham (inactive) tDCS stimulation, after 30 seconds of active stimulation, the electric current is cut off until the end of 20 minutes. Yes - There is a plan to make this available What will be shared: Information about study outcomes will be shared. When: The access period starts 6 months after the results are published To whom: Researchers working in academic institutions Conditions: Research in the relevant work area Where to obtain: Samaneh Valadbeigi - s.valadbeigi.99@gmail.com How to obtain: Sending the request from the applicant, checking it from the researcher and responding immediately Comments:
