Summary

The aim of this study will be to determine the effects of active tDCS on rotator cuff fatigue. This study will be a randomized, double-blind, sham-controlled, cross-over clinical trial based on non-probabilistic sampling for convenience, comprising a sample of 20 active asymptomatic subjects of all genders and aged between 18 and 35 years old. Subjects will be recruited via social networks, WhatsApp and emails and must be currently engaged in moderate physical activity (assessed by the IPAQ questionnaire) and asymptomatic at the time of assessment. In addition, participants will be asked not to perform any type of strenuous exercise and do not drink alcoholic or caffeinated beverages during the time the work is performed. The study will consist of three sessions, with an interval of 72 hours between them.

Interventions

Type	Name	Description
OTHER	Transcranial Direct Current Stimulation	The direct electric current will be applied through a pair of sponges humidified with saline solution (150 mMols of NaCl diluted in water Milli-Q) on the electrodes (35 cm2). The electrodes (anode and cathode) will be connected to a continuous electric stimulator (Model: Microestim Foco Research, Brand: NKL, Souza Cruz, Brusque - SC, Brazil), with one energy battery (9 V) and will be mounted in accordance with the International 10-20 EEG System. For anodal polarity stimulation over the left TC, the anodal electrode will be placed over the scalp on the T3 area located at 40% of the distance on the left from the Cz point. The cathode electrode will be placed over the contralateral supraorbital area (Fp2). Thereafter, a constant electric current of 2 mA will be applied for 20 min.
