Gait Analysis For Motion Sensors

Key Concepts in Gait Analysis for Motion Sensors

Gait analysis involves studying the mechanics of walking or running to identify patterns, abnormalities, or inefficiencies. Motion sensors, such as accelerometers, gyroscopes, and magnetometers, play a pivotal role in capturing real-time data. These sensors measure parameters like acceleration, angular velocity, and orientation, providing a detailed picture of an individual's movement. Key concepts include:

• Stride Length and Cadence: These metrics help assess the efficiency of movement.
• Joint Angles: Motion sensors track the angles of joints during movement, offering insights into biomechanics.
• Ground Reaction Forces: Understanding the forces exerted during foot contact is crucial for injury prevention.
• Symmetry and Balance: Identifying asymmetries can help address underlying issues.
