Abstract:
BACKGROUND:With the development of sports medicine and rehabilitation medicine, electromechanical delay has been looked as an important index for evaluating the neuromuscular function at abroad. But the relevant research is little reported in China. OBJECTIVE:To review the literatures related to electromechanical delay published in recent years, and to explore the mechanisms, influential factors and the application status of the electromechanical delay, thereby providing reference for clinical practice and research. METHODS:A computer-based search of CNKI, WanFang and PubMed databases was performed for articles addressing electromechanical delay published from February 1979 to February 2017. The keywords were electromechanical delay, electro-mechanical response time in English and Chinese, respectively.Repeated and old studies were excluded, and finally 44 eligible literatures were included, including 3 Chinese and 41 English articles. RESULTS AND CONCLUSION: The mechanisms of electromechanical delay have been clarified. The type of muscle fiber and the level of muscle fatigue can influence electromechanical delay, but the underlying mechanisms still remain unclear. Whether age and gender make effect on electromechanical delay is controversial. Electromechanical delay is not only used for evaluating the athletes' ability to reaction, but also wildly used to investigate the mechanism of various sports injuries and evaluate the effectiveness of rehabilitation.
