Application of plantar pressure analysis in medical diagnosis

Plantar pressure analysis is used primarily in medical diagnosis in the following areas:

1. Diagnosis of Foot Diseases

Identification of Structural Abnormalities

Flatfoot patients experience uniform arch pressure distribution, with significantly increased pressure in the forefoot and hindfoot.

High-arch foot patients experience pressure loss in the midfoot and concentrated pressure in the lateral metatarsal head.

Deformity Assessment

Ballux valgus patients experience abnormally increased pressure on the first metatarsal head, accompanied by altered heel valgus mechanics.

For patients with leg length discrepancy, quantifiable pressure asymmetry between the left and right feet can be used (e.g., a 1cm difference can cause knee pain).

2. Chronic Disease Management

Diabetic Foot Early Warning

Detection of localized high-pressure areas (commonly in the forefoot) helps prevent the risk of ulcers caused by neuropathy.

Assisted Diagnosis of Arthritis

Changes in dynamic pressure distribution on the affected side of patients with knee osteoarthritis are correlated with disease stage.

3. Rehabilitation and Prevention

Customized Orthotics: Designing cushioning insoles based on pressure distribution maps (e.g., diabetic foot decompression).

Child Development Monitoring: Early detection of splay gait improves intervention effectiveness by 40%.
