IRCT20161026030516N2 IRCT 2022-09-21 Tehran University of Medical Sciences Comparison of transcranial stimulation and stretching exercises on mental fatigue in slump posture Comparison of the effects of transcranial direct current stimulation and stretching exercises on mental fatigue using electroencephalographic parameters in people with slump posture 2022-10-12 anticipated 60 Complete https://irct.ir/trial/65653 interventional Randomization: N/A, Blinding: Not blinded, Placebo: Not used, Assignment: Crossover, Purpose: Diagnostic. N/A Slump posture. Intervention 1: First intervention group: in the present study, stretching exercises for trunk, neck and upper limb muscles are selected and taught to people. In total, it takes 10 minutes to do the exercises, This intervention is for the slump posture group to do before typing in one session.The interval between each session is considered to be one week, and the order of people's attendance in these sessions is follows: It randomly. Intervention 2: Intervention group 2: Another intervention is the use of transcranial direct stimulation. In the current study, the NEUROSTIM2 device produced by Medina Medicine Company of Iran will be used to provide electrical stimulation. The intervention is carried out using 3 x 5 cm square carbon plate electrodes with wet sponge coating. According to previous studies, stimulation of the left posterior lateral prefrontal cortex improves cognitive functions such as decision making, attention and working memory. Therefore, to stimulate this area, the anode electrode is placed on the F3 point according to the international 10-20 system, and the cathode electrode is placed on the opposite supraorbital area. To reduce skin resistance, the desired area is cleaned with cotton and alcohol as much as possible. The intensity of the stimulation will be 2 mA and its duration will be 10 minutes. The current first increased during the first 30 seconds to reach 2 mA and this value is maintained during 10 minutes until the last 30 s,that it reduces to 0. During the application of the current and also after its completion, the physical and mental conditions of the patient will be checked and if any side effects or discomfort are reported, the application of the current will be stopped if necessary. People in the posture slump group receive it in one of the three sessions of participating in the study, before typing. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is there is no more information
