Course Description
Balance assessment is a cornerstone of functional neurology practice, yet a persistent clinical question has lacked a direct answer: does the ambient noise of a working clinic introduce error into postural control testing? Unanswered, that question quietly undermines confidence in balance data collected under real-world conditions.
This course presents original research from Plasticity Brain Centers, led by Dr. Kenneth Jay, examining how clinical background noise, active noise canceling headphones, and white noise affect sway area in healthy individuals tested on the CAPS platform. Beyond resolving the noise question, the study surfaces a striking finding about the relative contributions of vision and proprioception to postural stability, one that challenges a widely held assumption about sensory hierarchy and offers clinicians a new interpretive lens for balance data.
What you’ll learn:
- Evaluate whether clinical office noise introduces error into postural control testing
- Interpret sway area ratios across surface firmness and visual input conditions
- Apply normative interaction data to enhance clinical balance interpretation
- Analyze the relative contributions of vision and proprioception to postural stability
- Assess fatiguing effects of repeated CAPS balance testing on sway performance
More About This Course
Clinical balance assessment sits at the intersection of functional neurology, rehabilitation science, and patient outcomes. As postural control testing becomes standard across chiropractic neurology, physical therapy, and functional medicine, clinicians using tools like the CAPS balance platform increasingly need research-level insight to interpret sway data with accuracy and confidence. This course addresses a precise and practical question that has long remained unanswered in the clinical neuroscience literature: does ambient office noise affect postural control measurements, and if so, what can clinicians do about it?
Presented by Dr. Kenneth Jay, Associate Director of Clinical Research at Plasticity Brain Centers, Associate Director of Clinical Education at UCF College of Medicine, and Assistant Professor at the Carrick Institute, this course delivers original research designed specifically to answer a real-world clinical challenge. Dr. Jay leads clinicians through the full architecture of the study: rationale, methodology, statistical approach, results, and clinical interpretation. The research used a three-factor repeated measures design, evaluating sway area across eight distinct noise conditions including silence, clinical office noise at 50 decibels, active noise canceling headphones, and white noise at both 55 and 75 decibels, on hard and soft surfaces, eyes open and eyes closed.
The findings resolve the noise confounding question with clinical confidence, and they surface something even more thought-provoking: a quantified breakdown of how surface firmness and visual input independently and interactively affect postural sway. The data challenges the conventional assumption that the visual system sits at the top of the sensory hierarchy for balance, revealing that proprioceptive disruption can be up to ten times more destabilizing than visual occlusion under specific conditions.
This course is designed for licensed clinicians who perform balance testing in practice, including chiropractors, functional neurologists, physical therapists, and rehabilitation specialists who want their clinical measurement to rest on a sound empirical foundation. One hour of continuing education credit is awarded upon completion.

Educational Syllabus
- Why Noise Became a Clinical Question Worth Answering
- Ambient office noise is an uncontrolled variable in most clinical balance settings. This topic frames the practical problem, the risk of type one error in postural testing, and why the literature offered no usable answer before this study.
- Study Design and the Science of Testing What You Cannot See
- Participants were tested across eight noise conditions on the CAPS platform, with three fixed factors and a rigorous statistical correction for multiple comparisons. Clinicians gain a model for understanding how balance research is designed and why these design choices matter for interpreting results.
- What the Data Actually Shows About Noise and Sway
- Across all noise conditions, sway area remained statistically unchanged. This topic walks through the results condition by condition, addresses clinical meaningfulness versus statistical significance, and resolves the ambient noise question with empirical confidence.
- The Sensory Hierarchy Finding That Changes How You Read Balance Data
- Proprioceptive disruption on a soft surface increased sway area by 279 percent compared to 35 percent for visual occlusion alone. This topic reframes the visual-vestibular-proprioceptive hierarchy and gives clinicians interpretive ratios to apply immediately in practice.
