IStride Roller Shoes to Give Stroke Victims Walking Back

A team from the University of South Florida (USA) led by Professor Kyle Reed has developed a simple but effective treatment for stroke victims. Patients who have undergone it very often have an asymmetric gait due to paralysis of one half of the body. Scientist-designed iStride shoes with a movable sole will help fix that.

The problem for people who have suffered a stroke is that their healthy leg moves in the usual rhythm, taking large and confident steps, and the partially paralyzed leg barely shifts and steps uncertainly on the ground. This leads to desynchronization of movements and difficulty in walking. Alas, a sore leg cannot be cured. This means that you need to teach a person to move a healthy leg to the beat of a weaker one.

The iStride device is designed as a shoe-strapped platform that has four lug wheels. They roll half a turn and hit the ground, so iStride automatically rolls the user's leg back half a step during the step. In this case, the structure sways slightly while the wheels rotate, but is rigidly fixed at the end of the movement. Thus, you have to control each step and move more slowly.

The teaching method is to select the appropriate iStride size for the patient, and simply put on shoes with thick soles on the injured leg to compensate for the difference in height. When walking, a person is forced to adjust the movements of the healthy leg to the movements of the weaker one, which after a month of training begins to happen automatically. There are no mechanisms or electronics in iStride, they are difficult to break and can be used for years to help all stroke victims learn to walk again.
