The Compatibility of Measuring Leg Stability with the Y Balance Test and MFT Challenge Disc in Adolescents

The study proposes the analysis of the compatibility between two methods of assessing leg stability: Y Balance Test (YBT) and the MFT Challenge Disc (MFT). 48 adolescents aged between 15 and 19, from the Moldova region (Romania) were measured. In girls, unilateral indexes correlated positively for both YBT (r = 0.73; p < 0.001) and MFT (r = 0.55; p = 0.001). Boys showed a relationship between the Y coefficient of the right leg and the MFT score (r = 0.51; p = 0.03). Overall, there are correlations between unilateral coefficients within each test, with only YBT having links between the score and the coefficient of the right (r = -0.33; p = 0.02) and left (r = 0.57; p < 0.001) leg. No links were found between the results of the two tests measuring leg stability in the respective teenagers.
