A portable gait analyzer is a device that records and analyzes human walking patterns in real time. It is widely used in rehabilitation, sports training, and foot health management.
I. Working Principle
Pressure Sensing Technology
Flexible pressure sensors are placed on insoles, foot pads, or walkway floors to record pressure changes in various areas of the foot during standing and walking. This can reveal key information such as landing sequence, uneven force distribution, and weight bearing differences between the left and right feet.
Inertial Measurement Unit
The device contains sensors such as an accelerometer and gyroscope to track foot acceleration, angular velocity, and sway amplitude, further analyzing stride length, cadence, gait rhythm, and walking stability.
Data Transmission and Analysis
Collected data is transmitted to a computer or mobile phone via Bluetooth or WiFi. The accompanying software automatically generates visual reports, including pressure distribution maps, gait cycle diagrams, and dynamic center of gravity trajectory, to assist in identifying abnormal gait patterns and functional impairments.
II. Price Range
Portable gait analyzers vary significantly in price depending on their configuration and purpose. They are generally as follows:
Entry-level: Suitable for individuals or foot massage parlors, their main functions are plantar pressure measurement and simple gait recognition, with prices ranging from 25,000 to 40,000 yuan.
Professional: Suitable for rehabilitation centers and sports training facilities, they support detailed gait cycle analysis, data export, and abnormality detection, with prices generally ranging from 30,000 to 55,000 yuan.
High-end medical: Used in hospitals and research institutions, they feature high-resolution pressure maps, 3D posture monitoring, and professional data reporting, with prices ranging from 55,000 to 80,000 yuan or more.
