Walking is one of the most basic and most popular forms of exercise for human beings. A normal adult walk does not require significant active thinking or exertion, because walking is an activity that is learned and mastered as a child. The normal human gait pattern is a smooth continuous motion along the forward direction, which is a natural repetition of the gait cycle as a basic unit. In a gait cycle, the two feet move forward further.
The basic skill of walking is that the two feet move forward step by step or bear the weight of the body and maintain the body balance when the opposite lower limbs move forward. Gait also involves people's behavioral habits, which are influenced by occupation, education, age, gender, and are also affected by various diseases.
In terms of ambiguity, gait is a periodic phenomenon that describes the characteristics of human walking, and each cycle can be divided into multiple parts for analysis. The walking period refers to the time course in which one lower limb finishes landing again from the foot landing, and is divided into a supporting phase and a swing phase according to the spatial position of the lower limb during walking. During the gait cycle, the muscles can precisely control the acceleration and deceleration of the limbs. The muscles must overcome the forces in the vertical direction of the ground reaction force, that is, overcome the gravity and generate forward thrust.
Contemporary research on gait analysis is basically based on humans, so we refer to "gait", which is generally referred to as the way humans behave. Gait is divided into normal gait and pathological gait.
Common pathological gait performance can be divided into the following categories: hemiplegia gait, paraplegic gait, gluteus maximus gait (body posture of the waist and bulging abdomen), gluteal muscle gait (duck step), quadriceps step State, cross-domain gait, joint tough gait, gait gait, panic gait (forward gait), short leg gait (both legs length), pain gait, etc.
The principle of correction is to identify as much as possible the cause of gait abnormalities and targeted gait training. So accurate gait analysis is essential.
"Sitting like a bell, standing like a pine, walking like a wind" is a standard for the ancients to behave well. A good posture can really make a person's external image better, and physiologically it can also benefit the health of the body.
The dynamic beauty of the human body allows people to feel the power of human nature through the display of various postures of the human body. The beauty of the human body's posture and movement is the beauty of the external form that the various parts of the human body coordinate and cooperate with, and it has the characteristics of dynamic beauty and beauty creation. First of all, the posture of beauty must be healthy, elegant and full of vitality.
The correct posture and posture help people to move their body parts in a balanced manner. It also makes the muscles develop more balanced and reduces the damage caused to different parts of the body. Many women walk in a swaying wind, swinging left and right, but they don't know that this walking posture is wrong, and it is easy to cause back pain and thick legs.
Gait analysis is an examination method for studying walking patterns. It reveals the key links and influencing factors of gait abnormalities through biomechanics and kinematics, thus guiding rehabilitation assessment and treatment, and also contributing to clinical diagnosis, efficacy evaluation, and mechanism research. It is a systematic study of the movement of an animal's limbs, or more precisely, a study of human walking. Research and analysis utilizes the observer's eyes and brain, and uses instruments to assist in measuring body movements, the body's mechanical structure, and muscle activity.
Gait analysis is used to assess, plan, and treat individual walking abilities. It is also often used in sports biomechanics to help athletes run more efficiently, and to identify whether the casualty is a posture-related or motion-related medical problem.
In simple terms, gait analysis is the analysis of human gait data through the instrument system, including plantar pressure distribution data, time data (such as the time of each step, swing time) and spatial data (such as the height and length of each step). ).
It usually requires professional intervention and operation in the laboratory. The gait analysis system mainly consists of a dynamic multi-dimensional force measuring platform, a pressure distribution, an electronic runway, a physiological surface electromyography acquisition and analysis system, and a kinematic three-dimensional image analysis system.
Widely used in ergonomics, biomechanics, rehabilitation medicine, sports medicine, physiology, clinical rehabilitation, muscle movement analysis, gait analysis, game production, three-dimensional dynamics and other fields.
