Univ. of Evansville

The Dunigan Lab
The lab is housed on the first floor of Graves Hall on the north side of the University of Evansville campus in Evansville Indiana. The lab is a 1250 sqaure foot facility newly renovated in 2011. It has easy access to parking and handicapped parking is available. While this is the physical location of the Dunigan Lab, the researchers and some of our equipment can easily travel as research and testing might require.
 
 
 
Vicon motion capture system
This 8 camera digit motion capture system collects 3 dimensional motion data during a variety of tasks. It is most often used in our lab to study lower extremity joint dysfunctions, balance control, and gait, but can just as easily be used to movements throughout the body or of the whole body. It collects kinematic information and can be combined with other hardware items in the lab to collect kinetic information at specific joints to enhance our analyses.



Bertec force plates
The lab is equipped with two 80 cm x 40 cm force plates. They collect 3 dimensional ground reaction forces and moments. In combination with our motion capture system we have the ability to study joint forces and moments during gait or any other task that involves contact with the ground.





 
DelSys EMG
We have the ability to test muscle activity via a method called "electromyography" (EMG). Our 16 channel system allows us to analyze 16 different muscles at once. This is beneficial for tasks that require many muscles like gait and balance control. This system is telemetric, allowing us to avoid wires getting in the way of normal performance. We also benefit from our collaboration with Dr. Frank Underwood, a professor within our department, whose credentials allow us to employ a fine-wire method to test muscles deep in the body, however normally we are able to capture most of our muscles of interest with non-invasive surface EMG

 
 
 
 
 
The isokinetic dynanometer allows for the measurement of individual joint torques (over time, speed and joint angles) at almost every major joint in the body. This system is an ingenious strength testing device that allows measurements isokinetically (constant velocity), isometrically (constant position), or isotonically (constant resistance). It also allows us to create a percise exercise program for patients.


 
 
 
The instrumented treadmill has embedded force plates underneath a dual-belt track. This device make prolonged gait or running research possible in the research lab. With the Bertec treadmill we can have people walk longer and faster, and collect information related to prolonged exposure to such tasks. With the inclination option, we can measure movement on up to 15° inclined or declined surfaces.



 
 
 
 

The Biodex Balance System is a measure of standing balance control. The sensory components that go into maintaining balance are tested while the user is tasked to maintain balance during platform pertubations. It measures balance by analyzing center of pressure (COP) trajectory.
