The purpose of the study is to determine the relationship and validity of the Sway Index as measured by the Biodex Balance System (BBS) compared to the Sway Index as measured by the modified-Clinical Test of Sensory Interaction on Balance (m-CTSIB) during a balance assessment protocol. The BBS score is determined by a computer, where the m-CTSIB score is determined subjectively by an individual. Balance is an important consideration when it comes to post-concussion treatments of athletes. To understand deficits or relationships, it is important to understand balance deficits in individuals who have obtained a concussion to determine return to play protocols. It is known that balance is affected following a concussion but clinicians do not always rely on objective measurements to clear participants to return to competition. This study would provide an objective tool that can be incorporated with the other determinants to return to play decisions. It is hypothesized that the Biodex Balance System Sway Index score will positively correlate with the m-CTSIB Sway Index score. Research Questions: 1. Is there a significant difference in stability index scores when comparing different stances among different trials? 2. Is there a significant difference between overall stability index scores when comparing between trials? 3. What is the test-retest reliability of the m-CTSIB protocol on the BBS? 4. Is there a correlation of stability index scores of the four stances between trials? 5. Is there a correlation between the traditional m-CTSIB protocol scores (measured by time held in testing position seconds) and the m-CTSIB scores as measured by the BBS (measured by overall stability index)? Study participants were recruited from The University of Akron campus and any volunteers who participanted through email or sign up sheets. This study will employ all of the participants who consented to the study. All the participants agreed to the criteria in this study they must were tested three times with at least a one week between each trial to collect data. Participants were excluded from the study if they had received a concussion prior to data collection. Before participation all subject signed a consent form that was IRB approved and all assessments were completed within approximately 20 minutes. modified-Clinical Test of Sensory Interaction on Balance Before administering the m-CTSIB the individual scoring and collecting data must have a foam pad (Power Systems Airex Balance Pad 81000), stopwatch, additional spotter, and the m-CTSIB Testing Protocol. The m-CTSIB test is made-up of four 30-second conditions. The participants will stand and perform the following: 1) double leg stances on a solid surface with eyes open and 2) double leg stances on a solid surface with eyes closed, then double leg stances on a foam pad with eyes open and double leg stances on foam pad with eyes closed. Prior to testing, the participant must be instructed to remove shoes and any ankle tape. The individual conducting the test must use a rehearsed script for each participant and undergo extensive training and competency testing before the study begins. This script will provide specific directions for each participant to follow. The participant will be instructed to assume the required m-CTSIB stance by placing their hands on their opposite shoulder and keeping their head up and eyes closed (Onate, Beck, and Van Lunen, 2007). Each foot of the participant will be placed by the administer to ensure consistency. When assessing the stances the time will stop when the participant reaches 30 seconds or the participant opens their eyes, takes a step, lifts their heel off the platform, stumbles, falls, moves hands from shoulders, or grasps the railing. The time for each trial will be added up for measurement an assessed. The maximum time is 2 minutes for all stances. Biodex Balance System (m-CTSIB) The Biodex Balance System (Biodex Balance SD) (BBS) default test for assessing postural instability is the modified Clinical Test of Sensory Integration and Balance. As a result, the m-CTSIB is the protocol that will be utilized in this study. All participants will be tested on the BBS in order to obtain week 1, week 2, and week 3 measurements. Before any data collection is obtained the tester must have proper training and experience in operating the BBS. In addition, the tester must use a rehearsed script for each participant in order to keep all data collection consistent. The tester must first set all of the parameters according to the m-CTSIB protocol. For example, each participant will perform four 30-second trials in a double leg stance. Participants will be instructed to perform the first two trials on a stable surface with 1) eyes-opened and 2) eyes-closed. Next, participants will have to maintain balance on an unstable surface (foam pad) with 1) eyes-opened and then 2) eyes-closed. This data will be saved in the computer system and then printed out for objective measurement assessments. If the participant cannot complete the 30-second trial it is recorded as `fall’ (Biodex Medical Systems, Inc., 2011).
