Clinical gait analysis,
built for your workflow

Koast turns video of a short walk in your clinic into 3D measures of joint motion and walking patterns. Orthopaedic clinicians and researchers can measure how a patient walks before treatment and track how their gait changes at follow-up.

How it works

From a short walk to clinical gait insights

01

Set up

Position smartphones or compatible video cameras along a clinic hallway or in a designated walking space. Leave them in place on fixed mounts or set them up when needed.

02

Capture

Use the Koast app to record a short walking trial with smartphones or other cameras. Koast automatically synchronizes and calibrates the recordings.

03

Review and download

Koast processes the recordings and generates a report showing walking measures and lower limb joint motion. Compare results with prior assessments and available reference data, or download processed data for further analysis and research.

Results

See how gait changes across visits

A short walking assessment captures 3D joint angles and summary measures of walking, such as speed and stride length. Compare a patient's results with their own baseline and with available reference data. Research teams can download processed gait measures and lower limb joint angle curves across the gait cycle for further analysis.

Developed through clinical biomechanics research

Developed through clinical biomechanics research

Koast grew out of decades of research on how people with joint disease walk and how their movement changes after treatment. We’ve compared Koast measurements with established 3D motion capture methods and tested the workflow in clinical settings.
