Researchers at Georgia Tech have designed a device, similar to radar guns used to catch speeding drivers, which can diagnose head trauma by analyzing the way a person walks.

The new system projects harmless microwaves at the body to produce a silhouette type image. From this image the device can analyze the movements of the arms, torso, and legs and detect small taletale signs of head trauma that appear in a person’s gait.

Radar Detects Head Trauma By Analyzing Gait

Repeated head trauma can often lead to long term brain damage, but even one concussion left undetected can put a person at risk from experiencing the same devastating symptoms. The problem is that it’s not always easy to spot concussions when they happen.

Symptoms of dizziness and sickness may not manifest in the fullest right away, instead they can gradually get worse as the day goes on. Plus, it’s almost considered normal to feel dizzy and lightheaded when you’ve taken a blow to the head, to point where most people try to shake it off and carry on about their way. This is likely one of the most common mistakes made by people suffering from a head injury; ANY injury that leaves you feeling dazed and lightheaded should certainly be checked out.

The system is still too large to be easily fitted in hospitals, clinics, sports facility and military bases, and more work needs to be done to make the diagnosis more accurate. However researchers are confident that the device can be cost effectively scaled down, and that they can make the necessary tweaks to system to make it more accurate.

If, or should I say when, that day comes; medical staff will have access to an almost instant method of diagnosing head trauma – a diagnosis that could save many from future brain damage.
