Gait Analyzer – Analysis and Application of Plantar Pressure Distribution System to Gait

Gait Analyzer – Analysis and Application of Plantar Pressure Distribution System

I. Working Principle and Technical Characteristics

The plantar pressure distribution system uses pressure sensing technology to accurately collect gait data. Its core is composed of a pressure plate with a built-in high-sensitivity sensor (such as capacitive and piezoresistive sensors), which can monitor the static pressure distribution of the plantar and dynamic gait cycle changes in real time.

Data Collection: Static measurement evaluates the arch shape and center of gravity distribution, and dynamic measurement captures the pressure change curve during walking.

Dynamic Analysis: Combined with three-dimensional motion capture technology, key parameters such as plantar pressure heat map, step length, step frequency, center of gravity trajectory, etc. are generated in real time.

Data Processing: Professional software is used to convert raw data into visual reports, supporting quantitative analysis of gait cycle, arch state, and abnormal stress points.

II. Core Functions and Evaluation Indicators

Morphology and Pressure Analysis

Morphological parameters: foot length, foot width, arch height (distinguishing abnormal foot types such as flat feet and high arches)

Pressure distribution: locate abnormal high-pressure areas in the forefoot, heel and other areas, and identify the early risks of plantar fasciitis and diabetic foot.

Dynamic gait: analyze step length, cadence, speed and gait symmetry, and detect abnormal patterns such as inversion/valgus and lameness.

Functional assessment and disease diagnosis

Sports injury warning: identify adverse force patterns (such as excessive internal rotation) during running or walking to reduce the risk of joint wear.

Disease screening: assist in the diagnosis of diseases such as diabetic foot, hallux valgus, plantar fasciitis, and reduce the risk of amputation through early intervention.

Rehabilitation monitoring: evaluate the gait recovery effect of patients with stroke and Parkinson’s disease, and optimize rehabilitation training programs.

III. Application scenarios and value

Medical field

Customized orthopedic devices: design personalized 3D printed insoles or orthopedic shoes based on foot pressure data to improve the balance of foot force.

Orthopedics and Endocrinology: used for correction of foot and ankle deformities, prevention of diabetic foot ulcers, and evaluation of postoperative rehabilitation effects.

Sports Science Field

Athlete Training Optimization: Analyze the biomechanical characteristics of sports and adjust the running posture to improve sports performance and prevent injuries.

Equipment Research and Development: Provide pressure distribution data support for sports shoe design and optimize cushioning and support performance.

Health Management and Child Care

Children’s Foot Development Monitoring: Screening for problems such as flat feet and valgus feet, and guiding early corrective intervention.

Elderly Health Management: Predict the risk of falling through gait stability assessment and formulate preventive measures.

Through the plantar pressure distribution system, gait analysis is upgraded from traditional empirical judgment to data-driven scientific decision-making, providing a reliable basis for clinical diagnosis and treatment, sports training and health management.
