The application scenarios of gait analysis systems for measuring plantar pressure distribution

The gait analysis system is an advanced biomechanical measurement tool for the foot, widely applied in clinical medicine, sports science, and rehabilitation training. Its core function is to measure plantar pressure distribution, capturing gait-related data to provide scientific evidence for studying and optimizing human movement patterns. The following elaborates on the specific application scenarios of gait analysis systems in measuring plantar pressure distribution across three major fields: medicine, sports, and rehabilitation.

1. Clinical Medical Applications
1.1 Disease Diagnosis and Treatment Evaluation
Gait analysis systems assist doctors in accurately identifying diseases associated with abnormal plantar pressure distribution, such as diabetic foot, flatfoot, high arches, and foot deformities.

• Diabetic Foot Prevention: Diabetic patients are prone to foot ulcers due to neuropathy and impaired blood circulation. Gait analysis systems can monitor changes in plantar pressure in real-time, identify high-pressure areas, and provide customized insoles to reduce ulcer risks.

• Flatfoot and High Arches: By analyzing the pressure center and distribution patterns, the system quantifies arch height and stability, guiding the design and evaluating the effectiveness of corrective insoles.

1.2 Surgical Planning and Postoperative Rehabilitation Monitoring
Gait analysis systems provide preoperative data support for lower limb surgeries (e.g., knee replacement, ankle repair), helping optimize surgical plans. During postoperative rehabilitation, the system tracks patients' gait recovery and adjusts rehabilitation plans based on plantar pressure data to ensure optimal functional recovery.

2. Sports Science Applications
2.1 Performance Optimization
In professional athletic training, gait analysis systems measure parameters like plantar pressure distribution, step length, and cadence to assess gait stability and energy efficiency.

• Running Sports: The system helps runners identify issues such as gait asymmetry or excessive pronation/supination, optimizing running posture and reducing injury risks.

• Competitive Sports: Gait analysis data provides scientific feedback for athletes, improving techniques and enhancing performance.

2.2 Injury Prevention and Recovery
Improper gait patterns are significant causes of sports injuries, such as plantar fasciitis, Achilles tendinitis, and tibial stress fractures. Gait analysis systems monitor gait dynamics in real-time, identifying risk factors and offering data-driven support for personalized prevention and recovery plans. For example, in plantar fasciitis recovery, the system evaluates treatment effectiveness and optimizes rehabilitation training by monitoring changes in plantar pressure distribution.

3. Rehabilitation Training Applications
3.1 Stroke and Neurological Disease Rehabilitation
Patients with stroke or other neurological disorders often exhibit gait abnormalities. Gait analysis systems quantify changes in walking ability, accurately recording metrics like gait symmetry, stance phase duration, and swing phase duration. These metrics provide scientific support for formulating and adjusting rehabilitation plans. Dynamic monitoring of pressure distribution allows physical therapists to evaluate the effectiveness of rehabilitation training in real-time and help patients gradually restore normal gait patterns.

3.2 Gait Assessment and Fall Prevention for the Elderly
Gait instability is a significant risk factor for falls in the elderly. Gait analysis systems evaluate gait characteristics in older adults, including gait symmetry, center of gravity stability, and step length changes. Based on plantar pressure data analysis, the system develops personalized gait training programs for the elderly, reducing fall risks and improving quality of life.

4. Future Development Directions
With advancements in sensor and data analysis technologies, gait analysis systems are evolving toward intelligence and portability. In the future, these systems will integrate more sensors to capture comprehensive gait data and utilize artificial intelligence algorithms for real-time analysis and feedback. For example, cloud-based gait analysis platforms could combine data with patients' medical records to provide doctors and patients with more accurate diagnostic and treatment suggestions. Additionally, the widespread use of portable devices will extend gait analysis applications from laboratories to daily life, offering continuous foot health monitoring to the general public.
