WICHITA, Kan. (AP) -- An entrepreneur with ties to Wichita State University has developed an iPhone application to assist with concussion detection and treatment.

The Wichita Eagle reports that the app, called the "Sway Balance," has won Food and Drug Administration approval. It was developed by Wichita State alumnus Chase Curtiss of Tulsa, Okla.

He tested the app at his alma mater and among hundreds of athletes at Wichita East and Andover Central high schools. It also was tested in Oklahoma and California.

Trainers ask an athlete who may have suffered a concussion to hold the iPhone or iPad on his or her own chest. Then the athletes are put through a series of tests, such as lifting their dominant foot.

The app compares those results to results from the beginning of the season.
