Effects of Transcutaneous Electrical Nerve Stimulation (TENS) to Improve the Cognitive Functions in Older Adults

Recent evidence has shown that transcutaneous electrical nerve stimulation (TENS) was effective in improving the cognitive function in healthy adult and people with dementia. However, lacking of evidence investigated the effect of TENS in improving the cognitive function and reversing the occurrence of dementia during the period of mild cognitive impairment (MCI), which is the crucial period to prevent the significant loss of cognition function. Therefore, the main objective of this study is to investigate the optimal TENS treatment protocol in improving the cognitive function in older adults with MCI.
