FAQ

Here are the top questions we get asked.

How have the outputs been validated?

We have validated all our metrics internally against industry standard measurement devices.  We also have several ongoing external validation projects in partnership with industry and academic biomechanics and gait labs. Our first two external validation papers will be published Q3 2020 in the Canadian Journal of Biomechanics.

What types of organizations is Plantiga suited for?

Plantiga is the ideal solution for any organization that manages the health and performance of a specific population. That includes physical therapy clinics, long term and acute care providers, outpatient, remote and telehealth services, military units, industrial health and safety programmes, athletic organizations, and fitness and training centres. 

Can I collect on multiple people at the same time?

Absolutely. The platform is easily scalable and could conceivably handle an unlimited amount of simultaneous data collection sessions.

What technologies are used?

We use signal processing and machine learning techniques to build and train algorithms. This allows us to solve a variety of challenges such as movement and gait phase identification, activity classification, load evaluation and continuous speed quantification.

What type of sensor is used?

We use a 6-axis IMU (triaxial accelerometer + triaxial gyroscope) under each foot.

Is the system wireless?

Due to our data density, we do not currently support live wireless data upload.  The sensor pod includes time synchronized, on-board data storage and data is uploaded to the cloud for processing via the docking station. We have plans to add wireless capabilities in future hardware iterations.

What are movement maps?

Movement maps plot the accelerations of all six axes of the IMU for the right and left foot during walk or run tests over the course of each step.  This visualization of individual gait patterns highlights movement symmetries and limb variabilities.

Does the system do pressure mapping?

Not currently. We use an accelerometry-based sensor system. Pressure sensors are valuable and we have plans to add them in the future, but for now, the system doesn’t report on weight transfer, COP, COM and other pressure derived metrics.
