Aspiration to enhance human capabilities by increasing cognitive functions and physical performance is a novel approach; however, mechanism to increase human performance to the highest level has been the topic of interest for the researchers since centuries. The activity of human brain can be altered through electrical stimulation that is purely noninvasive. Recently, Studies conducted by rehablitationists have emphasized the use of non-invasive electrical stimulation; one of the non-invasive brain stimulation (NIBS) techniques that induces excitability in human motor cortex is transcranial direct current stimulation (tDCS) that work by process of neuro modulation1. The advantages of NIBS are significant, as it has very rare or no adverse effects and does not require any kind of surgical procedure2. On the other hand, there are signifi-cant limitations in administering pharmacological treatments, causing non-specific effect and moderate to severe hostile effects3. While other contemporary physical and behavioral therapies are much safer and specific, depending on the available resources for therapist and training protocol and patient’s coopera-tion. There is therefore an evident unmet clinical need for the development of new therapeutic approaches in physical and rehabilitation medicine. NIBS is a new approach with positive clinical results explored in the last decade, these methods of brain stimulation are painless and can easily excite and modulate the brain functions. At present, various noninvasive electrical brain stimulation methods have been introduced by commercial providers and now been used by elite sports coaches, that are helping in improving the mental abilities, cognitive functions, balance and also assisting in dealing with the stress4. In general, neuromodula-tion of the human brain can be achieved noninvasively by delivering magnetic, electric and auditory and visual bursts of pulses5 to predefined cortical regions. So far, there is little empirical evidence for the efficacy of brain-stimulation techniques on enhancement of sports-specific performance6. Hence, as per my under-standing and knowledge the research work conducted on such approaches is scarce in Pakistan. Dear Editor, by the virtue of this prestigious journal I would like to draw your kind attention towards this unexplored area of research work, it seems plausible that these emerging techniques will be a future, legitimate way to enhance physical and mental performance.
