Application Case of Plantar Pressure Distribution System in Balance Training Equipment
Technical Application in Balance Training
The plantar pressure distribution system monitors the plantar pressure distribution of trainees in real time through a high-precision sensor array, providing objective quantitative data for balance training.
The system adopts piezoresistive sensor technology, with a sampling frequency of up to 100 Hz, capable of accurately capturing pressure changes of 0.1 N/cm². In balance training, the system can simultaneously record key parameters such as center of pressure (COP) trajectory, pressure peak value, and contact area, providing scientific basis for training effect evaluation.
Typical Application Cases
1.Functional Ankle Instability Rehabilitation Training
- Training method: single-leg standing training using a balance board combined with the plantar pressure feedback system.
- Data indicators: COP sway area, COP trajectory length, medial-lateral pressure ratio.
- Effect: maximum pressure of affected side reduced by 15–20% compared with healthy side, COP sway area reduced by 30%.
- Training period: 8 weeks, 3 times per week, 20 minutes each time.
2.Elderly Fall Prevention Training
- Training method: weight-shifting training on a balance pad combined with visual feedback.
- Data indicators: forefoot/rearfoot load ratio, pressure peak time, arch support index.
- Effect: forefoot load ratio increased by 12% after training, gait stability improved by 25%.
- Training period: 6 weeks, 2 times per week, 15 minutes each time.
3.Athlete Balance Ability Improvement
- Training method: core stability training on a BOSU ball combined with dynamic plantar pressure monitoring.
- Data indicators: pressure distribution symmetry, COP movement speed, support phase time.
- Effect: single-leg standing stability of soccer players improved by 18%, pressure distribution symmetry improved by 22%.
- Training period: 4 weeks, 4 times per week, 30 minutes each time.
