What does an impact test measure?

What is ImPACT? ImPACT is an objective tool to support trained healthcare providers in making sound return to activity decisions following concussions. It's a computerized test that measures memory, attention span, visual and verbal problem solving.

How do you do an impact test?

A pivoting arm is raised to a specific height (constant potential energy) and then released. The arm swings down hitting a notched sample, breaking the specimen. The energy absorbed by the sample is calculated from the height the arm swings to after hitting the sample.
