Abstract

The objective of this study was to evaluate the relations between Transcranial direct current stimulation (tDCS) by anodal current and the work fatigue in lower limb during isokinetic protocol. In this study was evaluated the knee extensors and flexors resulting torques, from an isokinetic assessment, in concentric / concentric muscular action, after tDCS by anodal and sham current. Results showed significant differences between anodal and sham conditions for average peak torque during knee extension phase and work fatigue during knee flexion phase. Anodal tDCS showed not to be a suitable technique to modulated primary motor cortex activity. The preliminary results indicate a negative effect on work fatigue (knee flexion phase) and average peak torque (knee extension phase).
