What is a gait analysis device?
Simply put, a gait analysis device is a system that uses pressure sensors, cameras or inertial modules to record dynamic information of a person walking or running. It can collect parameters such as sole pressure distribution, cadence, step length, center of gravity changes, knee joint angles, etc., to determine whether an individual has gait abnormalities.
These data are often used for:
Foot health assessment (such as flat feet, foot valgus)
Rehabilitation training tracking
Personalized customization of corrective insoles or shoes
Sports performance analysis and injury prevention
How many categories are there for gait analysis devices? How much is the price?
Gait analysis systems on the market can be roughly divided into the following categories according to functional complexity and application scenarios:
Plare pressure analysis system
I. Plantar pressure pads
Price range: ￥25,000～￥30,000
Suitable for: foot health stores, basic sports assessment centers, and orthopedic insole customization agencies.
Features:
Portable and easy to use
Captures the pressure distribution of the sole of the foot when standing and walking
Can be used with 3D scanners to assist in the design of insoles
Suitable for businesses that are just starting to provide foot health services, with low investment costs and a fast payback period.
2. Wearable gait analysis equipment
Price range: ￥20,000～￥80,000
Suitable for: sports training centers, rehabilitation and physiotherapy institutions, scientific research institutions.
Features:
Bound to the waist, legs and other positions through inertial sensors (IMU)
Capture dynamic gait data, including joint angles, stride, swing speed, etc.
No venue restrictions, convenient for outdoor analysis
Can generate dynamic charts and accurate analysis
Suitable for users or institutions with medium and high demands for dynamic sports data, with high cost performance.
3. Camera-based three-dimensional gait analysis system
Price range: ￥100,000～￥300,000+
Suitable for: high-end rehabilitation hospitals, sports research institutes, and headquarters of custom shoe brands.
Features:
Multiple high-speed cameras form an array, combined with infrared or marker tracking
Can reconstruct a full-body 3D skeletal dynamic model
Can accurately analyze the pelvis, knees, ankle joints, gait symmetry, etc.
Rich data dimensions, suitable for complex pathological analysis
Although the investment is high, it is highly accurate and professional, and is the first choice for large institutions.
In addition to hardware, don’t ignore software and service costs
Although many gait analysis devices are “hardware purchased once”, the software platform usually has:
Paid upgrade service
Cloud data storage function
Personalized modeling module
Technical support and training services
Therefore, it is recommended to consider the overall package price when budgeting, not only looking at the “equipment itself”, but also the “later use experience”.
