Motion Capture uses infrared cameras and reflective markers to measure human movement. Our motion capture system is specifically set-up for upper limb movement analysis.

• 12-camera Vicon Vero v.2.2 motion capture system

Electromyography (EMG) is a method for recording muscle activity (e.g., whether a muscle is “on” or “off”). Our EMG system can record from muscles near the skins surface using surface electrodes and muscles deep in the body using intramuscular needle electrodes.

• 32-channel Delsys Trigno EMG system
  • 8 Trigno Avanti Sensors (surface)
  • 8 Trigno Spring Contact Sensors (intramuscular)
  • 4 Trigno Quattro Sensors (surface)

Dynamometers are instruments used to measure force and torque. Our dynamometers can be used to examine strength in pediatric, adult, and elderly populations.

  • Work Simulation Attachments
• Hand Dynamometer for measuring grip strength
• Pinch Gauges for measuring pinch strength
• Custom Force Sensors are being developed to study finger forces

Ultrasound is a non-invasive imaging modality that can be used to measure muscle properties. Our ultrasound systems were chosen to optimize imaging of upper and lower limb musculature for research purposes.

YCB Object Set: The Yale-CMU-Berkeley (YCB) Object & Model Set is a collection of common household objects for benchmarking robotic manipulation. We are using the objects and models to study activities of daily living and to develop simulations of contact forces at the hand-object interface.

To facilitate analysis of experimental data and creation of predictive biomechanical simulations, we utilize a variety of engineering and data analysis software packages. We have licenses for Matlab, LabView, Nexus, and EMGworks. We also utilize many open-source software packages, including OpenSim, Python, PyTorch, NotePad++, OnShape, ImageJ, and Seg3D.
