Equipment

We capture out-of-lab data whenever and wherever possible. 

However, we hold physical lab space within the Amplifying Movement and Performance (AMP) Laboratory, which is a 5,500 sq-ft space equipped with two instrumented treadmills, a 6-m walkway embedded with 4 continuous force plates, and a 2.5- m trench for testing movement over various substrates.

MOTION CAPTURE

APDM inertial sensors

15 sensors set (Opal, 2-in x 2-in) equipped with acceleration (± 16g, ± 200g), gyroscope (± 2000 deg/s), and magnetometer (± Gauss) capabilities. Sensors can stream or log data in free-living environments up to 16-hours. Sensors are sync to each other, other systems, and can capture data at up to 800 Hz.

Qualisys motion capture system

10-camera Oqus motion capture system (8 Oqus 300 cameras, 2 Oqus 700 wide angle cameras). Data capture maximum is 500 Hz. Current capture volume is approximately 6 m L x 3.5 m W x 2.5 m H; additional capture length and height available through additional cameras. Measurement error is > 2 mm when calibrated for appropriate motion capture volumes. A Second motion capture system (Vicon) system to be installed shortly.

FORCE CAPTURE

Noraxon KinTREAD pressure treadmill

Treadmill features 10,270 pressure cells and can capture up to 300 Hz. Vertical ground reaction force is calculated from pressure data. Capable of speed up to 25 km/hr (0.1 increments) and 28% incline. Also have reverse belt capability.

Kistler multicomponent force plates

Four embedded force plates are located in the center of the motion analysis capture volume in the large motion capture space, including 3 Kistler 9260AA6 plates (60×50 cm) and 1 Kistler 9286BA plate (60×40 cm). Each multicomponent force plate provides ground reaction forces, moments, and center of pressure data for gait and balance analysis. Each force plate has a 5-10 kN vertical and 2.5 kN shear range, with excellent center of pressure accuracy (max error = ~2 mm in x/AP and y/ML directions).
