Study tracks electric scooter injuries at 2 hospitals

(CNN) – Electric scooters have taken over sidewalks and roadways in many metro areas in the United States.

New data is becoming available on injuries related to those scooters.

A study published in the medical journal Jama Network looked at injuries suffered by more than 200 people in two California hospitals over a year. Researchers found that 92 percent of those injured in scooter accidents were riders and only 4 percent of them wore helmets.

The study also included pedestrians hit by scooters, and people who stumbled over scooters on sidewalks.
