BALANCE SCORE FROM KR BALANCE KIT TO IDENTIFY A RISK OF CHRONIC ANKLE INSTABILITY
Keywords:
Chronic ankle instability, Balance, KR Balance Kit, Cumberland Ankle Instability ToolAbstract
Chronic Ankle Instability (CAI) is the most common injury among athletes and active population which may consequently impair balance and lead to falls. The KR balance kit, a device that has been developed for balance assessment, may be used to identify a risk of developing CAI conditions. Therefore, this study aimed to: 1) determine the KR balance cut-off score, a value that obtained from the KR balance kit to identify the risk of CAI conditions and 2) compare the KR balance score between individuals with and without CAI. A total of 114 participants were divided into 2 groups: 1) CAI (n=57) and 2) Non-Chronic Ankle Instability (NCAI) groups (n=57) by using the Cumberland Ankle Instability Tool (CAIT). Then, each participant was tested by the KR balance kit for 10 seconds, performing 3 times. The average KR balance scores were compared between groups. The KR balance cut-off score was subsequently calculated by applying the ROC curve and area under the curve (AUC). The results showed that the KR balance cut-off score > 2.96 referred to have the risk of CAI conditions (sensitivity = 0.702, specificity = 0.807, and accuracy = 81%). In addition, the CAI group was found statistical significantly greater sway than the NCAI group (p < 0.01). In accordance with the CAIT score, the KR balance kit could be utilized in identifying the risk of CAI conditions. To conclude, the KR balance kit may be an alternative device to assess the risk of CAI conditions for sports personnel and general population since it is practical and easy to use, especially in a fieldwork.
