Do you really know how to walk or run? PocketLab's tactile pressure sensor provides for an opportunity for your students to investigate foot pressure during these activities. Improper form can ultimately lead to unwanted visits to a podiatrist. Whenever you take a step, your body places pressure on muscles, joints and tendons in your legs, knees, ankles, feet and toes. Controlling heel pressure is a key factor to prevent injuries in this regard.
