Biomotion Lab Infrastructure

The Stanford Biomotion Lab conducts a variety of studies involving different types of testing apparatus. Below are descriptions of the main equipment used in the lab and a view of the main gait testing room.

The main room of the Biomotion Lab, used to conduct gait tests. The room is approximately 24' wide x 36' long x 12' high, allowing subjects to perform a variety of activities from walking and stair climbing to running and cutting.

The gait laboratory is equipped with three motion capture systems (image on the left): an 8-camera Qualisys retroflective marker based motion capture system (right), as well as two sets of 8 color video cameras (80 fps (left) and 205 fps (center)) used for markerless motion capture.

Two Bertec force plates in the floor capture synchronized ground force data to use in all three motion capture systems.

A Cyberware WBX 3D laser scanner is used to generate high-resolution models of the body to use in markerless motion capture. The entire surface of the body is scanned in 20 seconds with 4mm resolution. Not pictured, a Cyberware Desktop 3D scanner is also used as part of the cartilage morphology study to calculate the thickness of animal and cadaver knee articular cartilage.

A Cybex-II isokinetic dynamometer is used to measure flexor and extensor strength (left) and a KT-1000 device is used to measure knee laxity (right).
