Star excursion balance test (SEBT) can be used in different fields to asses balance and postural control, but no sufficient information about how the predictive factors (height, leg length, gender, weight and habits) can affect the performance of the SEBT. To determine if the predictive factors (height, leg length, gender, weight and habits) effect or interfere with the performance of the SEBT. 74 healthy participants, 37 male, 37 female The SEBT was performed three times by each participant. 5 min rest was given after each attempt. The SEBT, the reaching distance in each of the eight directions was labelled and measured after completing each attempt. Strong correlations were found between, Dominant leg length (stance leg), nondominant leg length (swing leg), height, weight, gender and reaching distance in all of the reaching directions This study demonstrates thevarious predictive factors (Height, stance leg length, swing leg length, weight, and gender) must be taken in consideration during the performance of the SEBT. As this factors affect the performance of the SEBT strongly.
