Apparatus for human gait manipulation

An apparatus for human gait manipulation, comprising:

• a treadmill belt configured to travel within a hollow treadmill frame upon rotating elements having axes perpendicular to a direction of the travel;
• a first barrier;
• and
• a second barrier,
• a third barrier, and
• an external mechanical obstacle module comprising an extendable/retractable rod-shaped obstacle,
• wherein the first, second and third barriers are equidistantly positioned along a length of the treadmill belt
• wherein the extendable/retractable rod-shaped obstacle is configured to extend lengthwise perpendicular to a first and second lengthwise edge of the treadmill belt across no more than 60% of the width of the treadmill belt of the apparatus from the external mechanical obstacle module,
• wherein the first, second and third barriers are arranged on the top surface of the treadmill belt between the first lengthwise edge and the second lengthwise edge of the treadmill belt,
• wherein the first, second and third barriers are reversibly fastened to the treadmill belt and are interchangeably positionable along the first lengthwise edge and the second lengthwise edge of the treadmill belt,
• wherein the first, second and third barriers extend no more than 75% of a width between the first and second lengthwise edge,
• wherein the first, second and third barriers on the treadmill belt are configured to modify movement of only one foot of a person on the apparatus, and
• wherein a distance between the first lengthwise edge and the second lengthwise edge of the treadmill belt defines the width of the treadmill belt.
