Facility

Konczak lab entrance Welcome to the lab

The laboratory is a state-of-art facility of approximately 180 square meters (2000 square ft) of total space. Next to office space and a reception area, two large laboratory rooms are available.

The movement physiology lab space is mostly devoted to the analysis of arm and hand function, while the motion capture lab is equipped to study gait and posture.

  

Konczak Motion Capture Lab Motion capture laboratory for gait and limb motion recording and assessment

The facility houses a 16-camera optoelectronic motion capture system with an embedded force platform to record human motion and associated ground reaction forces. The setup is suited to assess gait, standing balance and all forms of free whole-body motion within a 8 x 3m (24 x 9ft) space. A wireless 16-channel electromyographic recording system (EMG) is available to obtain data of the underlying muscle activation patterns during motion.

  

Passive motion apparatusPassive motion apparatus for the assessment of proprioceptive function

A research focus of the lab is to study proprioceptive or kinaesthetic function of children and adults. Several neurological diseases, such as dystonia and Parkinson's disease are known to be associated impairments in proprioception. This passive motion apparatus is used to investigate the motion or position sense of the forearm (i.e., how precise does someone perceive forearm motion or a change in its position).

  

wrist robotWrist robotic exoskeleton

This robotic device can either passively move the wrist/hand around its 3 degrees of freedom or it allows the user to interact actively with the robot.
The device is a development of researchers at the Italian Institute of Technology and Nanyang Technological University in Singapore.

wrist robotWe use this platform to develop assessment and traning protocols for neurorehabilitation.

  

Measureing deviceRecording muscle activity, foot pressure and joint movement

Electromyographic recordings of muscle activity is possible either through a wearable, wireless 16-channel system or through a wired system. In addition, an insole foot-pressure recording system is available to monitor changes in foot pressure during various gait and postural activities.

This photo shows the use of multiple recording systems for assessing the biomechanics of running. An electrogoniometer recorded knee motion, leg muscle activity was recorded using surface electrodes, and an specialized insole inserted into the shoe recorded the foot pressure through 99 sensors embedded into the insole.

  

Konczak lab workstations Lab workstations

The lab has numerous computer workstations available for the analysis of movement and electrophysiological data. Data obtained from a wide variety of sensors (motion capture systems, wireless EMG, electrogoniometers, passive motion apparatus, etc.) can be processed using manufacturer supplied software (e.g., Vicon, Biometrics) or custom-written software based on Matlab Technical Programming Language.
