Background: Falls have been implicated as the second highest cause of disability and death in the old population across the world. Some studies have shown that physical exercise applied alone and/or combined with non-invasive brain stimulation (NIBS) may improve mental activity and motor functions reducing the frail and the likelihood of falls. In this research was investigated whether physical and mental exercises training (PMET) combined with the NIBS procedure would reduce better the likelihood of falls in adult’s elderly as compared to the PMET by itself. Methods: A rigorous previous selective procedure was used for selecting 57 frail elderly subjects who were later randomly separated into two groups one of which nominated as experimental (FEG) and the other the control group (FCG). The FEG group practiced physical and mental exercises adjointly to a method of non-invasive brain stimulation. The FCG group received the same physical and mental exercises program as the FEG group practiced, but did not pass
