Small gait is walking slowly, with both feet rubbing the ground. It shows small steps, dragging, slow starting or turning, and unsteady gait. Gait refers to the posture of walking. When walking, the affected foot just point to the ground, the healthy foot will quickly start to move forward; the healthy foot touches the ground for a long time, the affected foot point to the ground for a short time. Human walking is a complex process, and its fundamental purpose is to move from one place to another safely and effectively. Walking (walking) is a characteristic human activity of moving the body through the interactive action of the feet. Gait is a behavioral characteristic of walking that involves behavioral habits, occupation, education, age and gender, and is also affected by a variety of diseases. Small gait refers to walking slowly, with both feet scraping the ground. It shows small steps, shuffling, slow starting or turning, and unsteady gait. A normal gait is smooth because of the minimal positioning of the center of gravity in the pelvis, combined with appropriate joint motion and appropriate strength, which, if not ensured, can lead to a small gait. Small gait due to diffuse brain damage (cerebral palsy) (e.g., scissor gait or dance gait due to cerebral palsy). Small gait due to cerebellar damage or disorders (“duck” gait) and small gait due to basal nucleus disorders (e.g., forward gait in Parkinson’s disease). Peripheral nerve damage (loss of innervation of specific muscle groups) is also common in clinical practice, such as gluteus maximus gait, gluteus medius gait, quadriceps gait, tibialis anterior gait, and gastrocnemius and flounder muscle weakness gait.
