Presentation
The gaitway 3D is a fully instrumented single belt treadmill including 4 strain gauge sensors measuring the vertical, fore-aft and lateral ground reaction forces during locomotion. The gaitway 3D is a joint development between Arsalis and h/p/cosmos (Germany). The gaitway 3D allows numerous strides of walking to be collected and analyzed in a limited lab space. It also allows single vertical foot contact forces to be decomposed during the double contact phase of walking according to an algorithm developed in collaboration with Université catholique de Louvain. The gaitway 3D has demonstrated outstanding accuracy and reliability allowing for online biofeedback on many parameters of the gait and for routine assessments in rehabilitation and sports medicine and in biomechanics research labs. The gaitway 3D can be interfaced with 3D motion tracking systems, electromyographs and metabolic energy expenditure measurement systems routinely used in gait analysis labs.

Functions
The gaitway 3D user software offers an easy access to a large number of functionalities including:
- Software setup in few clicks
- Patient & Operator database
- Integrated hardware control
- Patient weighing station
- Automatic gait detection (walk or run)
- Automatic decomposition of gait cycle
- Real time gait parameter computation
- Real time biofeedback
- Raw data export
- Automatic averaging of gait cycles
- Gait analysis for walking and running
- Left /Right cycles contrast
- Software update in few clicks
Biomechanical parameters
The gaitway 3D user software offers an online computation of many biomechanical parameters for each stride. All parameters are computed, for both sides when applicable, and can be used for biofeedback. After data acquisition, individual steps are automatically detected; strides are averaged and can be normalized. All parameters for the detected gait (walking or running) are reported in tables and plots, including:
- Step length, width, frequency
- Swing / stance durations
- Contact / aerial durations
- Stride asymmetry
- Center of pressure
- Force peaks (push-off, landing)
- Loading and unloading rate
- Vertical force on Left / Right foot
Applications
The gaitway 3D is a versatile single belt instrumented treadmill. Its applications include:
- Biomechanical & clinical gait research studies
- Pathological gait evaluation
- Gait rehabilitation
- Athletic performance assessment & training
Combined with a 3D tracking system, the gaitway 3D also allows detailed biomechanical analyses (e.g. inverse dynamics). The gaitway 3D is compatible with any 3D tracking system.
Benefits
- Rugged construction
- Standard certified product
- State of the art instrumentation
- High speed and accurate measurement
- Up to date & evolving user software
- Cost effective
