Plantar pressure distribution system as the core application of gait analyzer
The plantar pressure distribution system captures plantar pressure data in real time and combines it with dynamic gait analysis technology. It has the following key application scenarios in the fields of medicine, sports and rehabilitation:
1. Diabetic foot risk assessment and ulcer prevention
High-pressure area identification: Detect abnormal plantar pressure concentration areas (such as heels or forefoot), combine pressure-time change curves to assess skin damage risk, and guide early intervention for high-risk groups of diabetic foot.
Neuropathy monitoring: Through the uneven distribution of plantar pressure (such as abnormal local pressure peak), assist in the diagnosis of diabetic peripheral neuropathy and reduce the probability of ulcers.
2. Foot deformity diagnosis and correction
Arch status assessment: Quantify the arch height and collapse degree, distinguish between flat feet, high arches, and varus and valgus deformity types, and provide a basis for correction plans.
Hallux valgus and equinus analysis: Combine dynamic gait data (such as gait line deviation and pressure center trajectory) to assess the impact of deformity on walking stability.
3. Sports injury prevention and rehabilitation training
Sports technique optimization: Analyze the peak distribution of plantar pressure during running and jumping (such as excessive forefoot load), guide athletes to adjust the force mode, and reduce the risk of stress fractures.
Rehabilitation effect tracking: Quantify the effect of rehabilitation training (such as arch support recovery) by comparing the plantar pressure symmetry and gait cycle parameters before and after intervention.
4. Balance ability assessment and fall risk prediction
Static balance test: Measure the center of gravity deviation amplitude and pressure distribution symmetry when standing, and identify balance dysfunction in the elderly or patients with neurological diseases.
Dynamic gait stability: Analyze the swing range of the center of pressure (COP) trajectory during walking, predict the risk of falling and formulate prevention strategies.
5. Personalized orthopedic device design
3D printed insole customization: Based on the three-dimensional model of the plantar and the pressure heat map, generate orthopedic insoles that fit the foot shape, disperse local high pressure and improve the biomechanical line.
Shoe fit optimization: Recommend shoe type according to foot length, foot width and pressure distribution to reduce friction damage (such as wide toe design to relieve hallux valgus pressure).
6. Biomechanical research and sports technology optimization
Gait parameter extraction: Quantify indicators such as step length, pace, and foot contact time to study the rationality of sports technology (such as forefoot landing optimization for sprinters).
Analysis of plantar pressure patterns: Reveal the plantar load characteristics of different sports scenes (such as the buffering stage of jumping) to guide the shock absorption design of sports shoes.
7. Monitoring and early intervention of children’s foot development
Arch development assessment: Regularly scan the plantar morphology of children, identify developmental delays or abnormalities (such as flat foot tendency), and formulate early correction plans.
Gait abnormality screening: Through dynamic gait analysis, abnormal patterns such as inward and outward toe can be found to prevent the progression of skeletal deformities.
Summary of the value of technology applications
The plantar pressure distribution system achieves full-process management from disease screening to personalized intervention through multi-dimensional data fusion (static morphology + dynamic gait + biomechanics), significantly improving the accuracy of medical diagnosis and the scientific nature of sports training.
