(research assistant), Katie Kempf (DPT student), Alicen Whitaker (DPT/Ph.D. student), and Sophy Perdomo, Ph.D. (postdoctoral fellow)

The REACH Lab Team

Working under the supervision of Sandra Billinger, Ph.D., PT, the REACH Lab team includes a combination of current and former students in the rehabilitation science doctoral program in addition to those working toward a clinical doctorate in physical therapy.

The lab provides a collaborative learning environment where young scientists gain valuable experience with established researchers at the KU Medical Center.

The REACH Lab currently has affiliate relationships with the following organizations:

The REACH lab consists of state-of-the-art equipment that allows us to assess various aspects of cardiovascular fitness and exercise-training capabilities.

Cardiovascular Function

  • Space is temperature and humidity-controlled for accurate vascular assessments.
  • Siemens Acuson Sequoia 512 standard-resolution ultrasound for standard echocardiography, tissue Doppler imaging, and vessel imaging (e.g. endothelial function, carotid IMT)
  • GE Logiq P5
  • SphygmaCor for pulse-wave analyses, measurement of arterial stiffness, and central blood pressure
  • Finometer Pro, a non-invasive beat-to-beat blood pressure monitor for acquisition of hemodynamic variables
  • Two Hokanson Rapid Cuff Inflation systems for determining resistance vessel vasodilatory capacity
  • Metlab Data Acquisition system with multichannel interface
  • Vascular research tools: automated software to analyze vascular ultrasound images for measures of endothelial function (e.g. flow-mediated dilation)

Cerebrovascular Function

  • Multigon trans-cranial Doppler ultrasound with robotic headband to detect blood flow patterns in the large arteries of the brain at rest and during exercise
  • Transfer function analysis

Exercise Testing and Training

  • Parvo Medics True One 2400 oxygen uptake unit and 12-lead ECG unit
  • Oxycon portable oxygen uptake unit
  • Trackmaster motorized treadmill and Lode Excalibur Sport Cycle Ergometer
  • Actigraph physical activity monitors
  • Three NuSteps, two T5XR treadmills, elipitical trainer, and cycle ergometers
  • Full circuit of resistance equipment
  • Biodex dynamometer

Additional Capabilities

  • Space for blood draws
  • Space for function testing by trained personnel
  • Six-minute walk test
  • Balance tests
  • Small conference room for meetings
