Lab Description:

Arthur J. Nelson, Jr. Human Performance Laboratory

Faculty and graduate student research is conducted at the Department of Physical Therapy's Arthur J. Nelson Jr. Human Performance Laboratory. This state-of-the-art facility includes 2000 square feet of dedicated research space. Our primary research focus is in the area of pathokinesiology where motor control, cardiopulmonary, and biomechanical issues are investigated in both healthy and patient populations.  Five full-time physical therapy members conduct research with collaborators in the New York metropolitan area and mentor M.A. and Ph.D. student research.

Lab Equipment:
  • Isokinetic dynamometer (Biodex, Shirley, NY)
  • Three dimensional motion capture system (Qualisys, Gothenburg, Sweden) with real-time motion capture and analysis capabilities
  • Force plates and amplifiers (Kistler Inc, Amherst, NY)
  • Eight channel EMG (Delsys, Boston, MA) with bipolar pre-amplified electrodes
  • Two four-channel EMG units (Therapeutics Unlimited, Iowa City, IA) with bipolar pre-amplified electrodes
  • In-shoe pressure measuring system (Pedar Inc, St Paul, MN) and Novel Database software
  • Oscilloscope (Tektonix, Beaverton, OR), Accelerometers (Kistler Inc, Amherst, NY), Foot switches (Manufacturer), Electrogoniometers (Manufacturer), External trigger (custom built), 64 channel A/D Board
  • Metabolic cart (Physiodyne, AEI Technologies, PA) with EKG, calibrated treadmill and bicycle ergometer
  • Infrared timing systems (FarmTek, Wylie, TX)
  • Instrumented electronic walkway (GaitRite, CIR Systems, PA)
  • Digital camera and camcorder (Canon Vixia HF10)
Specialized Software, Computing, and Other Resources:
  • Visual3D (C-motion Inc, Bethesda, MD)
  • Labview 8.6 (National Instruments, Austin, TX)
  • SPSS 19 (IBM, Somers, NY)
  • PASS (NCSS, Kaysville, UT)
  • Four dedicated desktops, three laptops with data acquisition capabilities (NI DAQ)
