Sensory Processing and Stress Evaluation Lab
About the Lab
The Department of Occupational Therapy Kathryn Lawrence Dragas Sensory Processing And Stress Evaluation (SPASE) Lab was established in 2004 as an environment in which researchers could examine the physiological mechanisms underlying disorders in sensory integration and processing. The global aims of the SPASE Lab at VCU are to:
- Examine the causes and prevalence of sensory integration and processing disorders;
- Establish a differential diagnosis of sensory integration and processing disorders, distinguishing them from other conditions such as Autism and ADHD;
- Identify neurologic, physiologic and biochemical markers associated with sensory integration and processing disorders.
- Examine best practice for working with children with sensory integration and processing disorders.
- Test novel sensory-based interventions for improving performance, sleep, and stress levels in children and adults with developmental disorders.
Space and Equipment
The SPASE lab is located at 900 E. Leigh Street in the College of Health Professions Building (Rooms 5007 & 5009). The lab is 300 square feet divided into two rooms; a primary testing room and a parent/researcher observation room. The two rooms are divided by a one-way mirror; pan-tilt-zoom cameras are also installed in the primary testing space and can be controlled in the observation room for both recording and observational purpose.
We have research-grade technology to measure electrodermal reactivity, cardiac vagal tone, and cardiac impedence (Mindware Technology), as well as activity patterns and sleep (Actigraph GT9X watches). Our lab uses E-Prime 3 for stimulus delivery during our sensory paradigms which is integrated with our Mindware system. We also have Noldus software for video coding and analysis of observable behaviors. Intervention equipment includes Touchpoints, wristbands, an Interactive Metronome system and pressure vests (Vayu). We also have access to shared lab space within the Department of Occupational Therapy at VCU to conduct sensory integration intervention; this space has suspension points for swings as well as a variety of other equipment which adheres to the fidelity standards for Ayres Sensory Integration®.
Funding and Current Projects
Research in our lab has been funded by the American Occupational Therapy Foundation, the National Institutes of Health, the Barth Syndrome Foundation, the Wallace Foundation, the Virginia Commonwealth University, Presidential Research Initiative Program, and the AD Williams Research fund at VCU. Research in our lab has yielded over 35 publications in the last 10 years and numerous state, national, and international publications. We are also proud to have mentored over 20 students who have either worked in the lab as research assistants or completed research projects in the lab as part of their dissertation/thesis work. Several of these students have gone on to accept teaching or research positions at other universities and are now mentoring other students.
The studies we are currently running are listed below:
- Comparing a parent -report measure to performance-based measures of vestibular function
- Physiological Reactivity in Children with Sound Sensitivity
- Comparing measures of sensation seeking in occupational therapy and psychology: A pilot study
- The effects of sensory integration therapy on brain structure and connectivity in children with developmental coordination disorder
- A longitudinal investigation into motor development patterns in Barth Syndrome
Stacey Reynolds, PhD, OTR/L
- Reynolds is an Associate Professor in the Department of Occupational Therapy at Virginia Commonwealth University (VCU). She received her M.S. in Occupational Therapy from Gannon University and her PhD in Health Science with emphasis in Occupational Therapy at Virginia Commonwealth University. In 2010 she was accepted into the Rehabilitation Research and Career Development (RRCD) program at the University of Florida and completed 2.5 years of mentored training in the area of behavioral neuroscience. In addition to twenty years of clinical experience, Dr. Reynolds has completed multiple funded research projects related to the etiology and characterization of sensory-motor disorders in neurodevelopmental disabilities using both human and animal models. Dr. Reynolds also holds the position of Editor-in-Chief of the American Journal of Occupational Therapy (AJOT), the highest ranked occupational therapy journal in the world.
