Abstract

Balance is a complex construct, affected by multiple components such as strength and coordination. However, while assessing an athlete's dynamic balance is an important part of clinical examination there is no gold standard measure. The multiple single-leg hop-stabilization test (MSLHST) is a functional test which may offer a method of evaluating the dynamic attributes of balance, but it needs to show adequate intra-tester reliability. The purpose of this study was to assess the intra-rater reliability of a dynamic balance test, the multiple single-leg hop-stabilization test (MSLHST) on the dominant and non-dominant legs. Fifteen active participants were tested twice with a 10-minute break between tests. The outcome measure was the multiple single-leg hop-stabilization test score, based on a clinically assessed numerical scoring system. Results were analyzed using an Intra-class Correlations Coefficient (ICC 2,1) and Bland-Altman plots. Regression analyses explored relationships between test scores, leg dominance, age and training (an alpha level of p = 0.05 was selected). ICCs for intra-rater reliability were 0.85 for the dominant and non-dominant legs (confidence intervals = 0.62-0.95 and 0.61-0.95 respectively). Bland-Altman plots showed scores within two standard deviations. A significant correlation was observed between the dominant and non-dominant leg on balance scores (R²=0.49, p<0.05), and better balance was associated with younger participants in their non-dominant leg (R²=0.28, p<0.05) and their dominant leg (R²=0.39, p<0.05) and a higher number of hours spent training for the non-dominant leg R²=0.37, p<0.05). The authors concluded that the multiple single-leg hop-stabilization test demonstrated strong intra-tester reliability with active participants. Younger participants who trained more, have better balance scores. This test may be a useful measure for evaluating the dynamic attributes of balance.
