Ankle strategies play an important role in controlling posture and hockey’s performance. However, the study of postural balance in hockey’s athletes with ankle injury was limited. The aim of this study was to compare balance between hockey athletes with and without previous ankle injuries. Hockey athletes aged 13-22 years old who had (n=17) and had not been (n=17) suffered from ankle injury in the past 6 months were participated. They underwent anthropometry including body mass index, and leg length. The static and dynamic balance was randomly measured by using the balance error scoring system (BESS) and the star excursion balance test (SEBT), respectively. The group difference in each parameter was analyzed using Independent T- Test. It was found that previously injured athletes had a total BESS error score and SEBT score comparable to those of peer group who had no history of ankle injury (p>0.05). After normalized SEBT score to limb length, both injured and non-injured groups had no different balance ability in anterior and posteromedial directions (p>0.05) except posterolateral direction. These results suggested that hockey athletes with ankle injury could maintain their static and dynamic postural balance. However, their deficit of ankle eversion still remained.
