Effect of protruding stickers enhancing plantar sensory feedback on control of the center of force trajectory during gait: A preliminary study.

Background: Abnormal kinematics and kinetics in the lower extremity during gait may be improved by modulating the center of force trajectory of the foot. This study aimed to confirm whether short-interval training using plastic hemispherical protruding stickers (diameter: 5 mm; height: 2 mm) attached to the plantar surface of the foot to enhance plantar sensory feedback can help actively control the center of force trajectory during gait.

Methods: Twenty healthy female subjects underwent three-dimensional barefoot gait analysis under control conditions and two post-training conditions.
