Improving trunk muscle strength and endurance is one of the many goals to be achieved in rehabilitation protocols for a variety of health conditions. Cerebral electrical stimulations techniques, such as transcranial direct current stimulation (tDCS) can modulate motor brain areas involved in motor functions. However, their effects on trunk function are lacking. This study aims to investigate the effects of transcranial direct current stimulation (tDCS) on trunk muscle strength and endurance in healthy subjects.
