My name is Ziyin Liu, a MSC candidate from China Shandong Sport University, majoring in Sports Rehabilitation, and I will graduate in July 2024. I have done a lot of work on ankle sprains. E.g., I am currently researching "Longer Peroneal Reaction Time in People with Chronic Ankle Instability Lines in Mechanoreceptor Delay from Sending Signals Rather Than Prolonged Peripheral Nerve Conduction". Using the Hoffman reflex and trap door tests, I tried to confirm whether the delayed peroneal reaction time is caused by the slower nerve translation or the later signal sent from receptors.
