Summary

The goal of this study has two parts. First, it examines whether performing multiple Sensory Organization Tests (SOT) on the SMART Balance Master, using two different testing orders, leads to different levels of practice effects-meaning improvements in balance scores with repeated testing. Second, the study evaluates how reliable the SOT is over time by using two different postural stability measures and two different testing orders. The testing schedule follows the same time intervals commonly used in pre- and post-concussion assessments.

The main hypothesis is that the order of testing-whether done in a blocked or random sequence-affects practice effects on composite and sub-composite balance scores over five repeated SOT sessions.

The second hypothesis is that the multiscale entropy (MSE) complexity index will show consistent test-retest reliability across both blocked and random testing groups when following clinical concussion management timelines.

Participants will complete five SOT sessions on the SMART Balance Master: three tests in one day with 20-minute breaks in between, followed by a test on day 45 and another on day 50.

Interventions

DEVICE

Reliability of the Sensory Organization Test on the SMART Balance Master across multiple administrations

The Sensory Organization Test (SOT) on the SMART Balance Master® will be administered a total of five times. On the first day, participants will complete three SOT sessions, each separated by a 20-minute break. An additional SOT will be conducted on day 45, followed by a final SOT on day 50. SOT test scores will be analyzed using Equilibrium Scores (ESs), which provide information on the integration of multiple sensory systems involved in balance through a linear measurement method. Additionally, scores will be evaluated using Multiscale Entropy (MSE), a non-linear model for assessing complexity in postural stability.
