The gait analyzer quantitatively evaluates the walking posture of the human body by comprehensively applying a variety of biomechanical and kinematic technologies. Its core principles and functions are as follows:
I. Working principle
Pressure sensing technology
Record the static/dynamic pressure distribution of the sole through piezoelectric, capacitive or piezoresistive sensors, generate pressure heat maps and analyze parameters such as center of gravity trajectory and gait cycle.
Motion capture technology
Use inertial sensors (IMU) or optical three-dimensional motion capture systems to track kinematic data such as joint angles, step lengths, and step frequencies in real time.
Video analysis technology
Combined with high-speed camera and AI algorithm, it automatically identifies abnormal gait patterns (such as inversion of the foot and asymmetric gait).
II. Main functions
Clinical medical evaluation
Orthopedics and rehabilitation: Quantitatively evaluate the gait recovery of patients after fractures and joint replacements, and optimize rehabilitation training programs.
Foot disease diagnosis: Identify structural abnormalities such as flat feet and high arches, and assist in early screening of diabetic foot.
Neurological disease analysis
Monitor the gait stability of patients with Parkinson’s disease and stroke, and evaluate the degree of motor dysfunction and rehabilitation progress.
Sports medicine optimization
Prevent sports injuries: analyze the force pattern of the soles of the feet during running and jumping, and correct the risk of center of gravity shift.
Improve sports performance: optimize the gait efficiency of athletes based on three-dimensional motion capture data.
Personalized orthopedic design
Customize 3D printed orthopedic insoles or braces based on the plantar pressure distribution to improve gait stability.
Through multi-dimensional data integration, the device provides accurate quantitative basis for disease diagnosis, rehabilitation treatment and sports optimization.
