Ultrasound Headset May be New Way to Recognize Concussion on Sidelines
In this study, researchers used transcranial Doppler (TCD) to track the blood flow in the brain to see if they could differentiate between athletes who had suffered a concussion compared to those who had not. This study is based on the growing evidence that concussions can change the blood flow in the brain. Athletes who were studied either played a contact sport (football, basketball, hockey, soccer, water polo or lacrosse) or a non-contact sport (cheerleading, cross country, cycling, tennis or track). Each athlete in the study had their brain studied using the TCD within six days of suffering from their concussion. The study found that the TCD ultrasound was able to differentiate between health and concussed athletes 83 percent of the time. “This research suggests that this advanced from of ultrasound may provide a more accurate diagnosis of concussion,” said Hamilton. “While more research is needed, the hope is such a tool could one day be used on the sidelines to help determine more quickly whether an athlete needs further testing.” To read more, click here.
