Device Shows Concussion Effects Linger Off The Field

It’s an August tradition: Football training camps open, and we’re treated to warnings about working out in the heat.

In the past few years, however, when it comes to football, there’s been a new emphasis on traumatic brain injury (TBI). This has caught our eyes here at MedGadget.

We’ve covered innovative impact-sensing helmet technology before (as well as smart helmets for temperature monitoring). But for the athlete with a concussion, what happens off the field? Unless a neurologist is involved, it’s up to the players and trainers to follow guidelines or make guesses about when to return to play.

Hopefully that will change, and a device like BrainScope will lead the way. When we first covered BrainScope, they were positioning their new device, based on controversial technology, as a sideline decision-making aide. Now their research seems to be focused on the weeks and months post-concussion. Read more »

The Human Arm: An Information Superhighway?

Scientists at Korea University in Seoul have demonstrated a prototype of a new biomonitoring system that transmits data through the body, replacing wires and minimizing the need for batteries.

The device is 300 micrometres thick and in a test, using a metal electrode coated with a flexible silicon-rich polymer, the researchers transmitted data at a rate of 10 megabits per second through a person’s arm. The device was tested for skin safety after continuous wearing and the data was transmitted via low-frequency electromagnetic waves through the skin.

The technology may have implications for diagnostics, as it can be used to detect electric fluctuations as is currently done by ECG and EEG machines.

The Spirit Of The Place: Samuel Shem’s New Book May Depress You

When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…

Eat To Save Your Life: Another Half-True Diet Book

I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
