BACKGROUND: Data collected from gyroscopes and accelerometers as well as force plates have been found to have a strong correlation according to various research studies. (cite). The Modified Clinical Test of Sensory Interaction and Balance (mCTSIB) is a tool commonly used to assess postural sway with a focus on sensory contributions. Few studies are available directly comparing the “score” data collected by specific systems.

METHODS: All testing was done on-site at SFU. A consent form was provided to subjects. Subjects were given instruction once and then performed the mCTSIB accord-ing to the specific protocol of each device, with participants alternating which test was performed first. Subjects completed the mCTSIB two times in total. The iPad and harness was worn during both trials. Data was recorded and an-alyzed for any correlation. During pilot testing, it was revealed that due to the protocols on the software, the timing of the tests would not match up correctly for data collection. (SWAY 30 sec, VSR Sport 3, 10 sec increments) Four trials were completed for each device: Eyes open firm surface, eyes closed firm surface, eyes open foam surface, eyes closed foam surface

CONCLUSION: Moderate inverse correlation was found between scores during the following trials: Eyes closed on firm surface (p = 0.0011), Eyes closed on foam surface (p = 0.0006), Composite score of all four trials (p = 0.0008). The SWAY Balance System may be an effective and viable tool for balance as-sessment. Further research is needed using different SWAY Balance System protocols to determine if it is a reasonable alternative for use with concussed individuals.
