What is a video analysis?
GAIT video analysis is a process in which a runner or pedestrian is on a video tape. The computer analyst monitors the video at regular speed, slow movement and stop movement to assess the individual step. Athletes and people who have difficulty walking benefit from the analysis of video walking. Athletes benefit from video analysis because the analyst can observe a step and shows athletes who can move more efficiently, either faster or prevent injury. People who have trouble walking benefits from the video analysis, because the analyst can point out the problems related to the movement and posture that a person could correct the therapy.
Video Walk analysis takes place in a laboratory equipped with more cameras located around a treadmill. Runner or Walker has small reflective marks located on various monuments on his body, such as knee, ankle and pelvis points. The patient walks or runs for about 30 seconds. Movement of brands is trascked by a computer that calculates strength and trajectory in eachpoint to the point. The computer model provides an analyst with a detailed analysis of movement in each joint.
One of the common types of video analysis is to find out how the runner places his leg while running. The runner's leg that has a neutral step moves in perfect alignment from knee to leg. During the running step, the leg of the excessive propronor moves inside. A runner who finds sub -pro -corners that his leg moves out while running. Once diagnosed, there are therapeutic shoes and inserts that can help neutralize step and relieve stress from below or excessively.
One form of video analysis is used to determine the risk of human fall. This method uses a scale of evaluation of bits abnormality (GARS). Gars analyzes 16 different parts of the body, five, seven on the trunk, the upper body and the head and four on the lower body. Each area is given by evaluation from scratch, which is good, up to three, which is bad. CombineThe score provides the baseline to determine whether the participant is exposed to a high risk of falls.
The relatively new use for analyzing video walking is in the field of biometry. Biometry is a process used to identify people, based on certain, unchanging aspects of their body or character. Walk analysis falls under behavioral biometrics, which also includes voice and written rhythm. The second form of biometry is physiological, which includes identity projections such as palms and fingers, DNA and IRIS and facial recognition.
