[Purpose] In this study, we investigated the relationship between balance and muscle power in postural control. [Subjests] Subjects were 21 healthy individuals. [Methods] First, static balance was assessed using a Romberg balance test (standing with eyes opened and eyes closed) combined with a GRAVICORDER® (Anima, Japan). Then, we assessed active balance with the EQUITEST SYSTEM® (NEUROCOM, Clackamas, USA). Subjects' muscle strength was determined by knee extensor strength and knee extensor time to peak torque using a Biodex® (Biodex, USA), and by ankle plantar flexion and ankle dorsiflexion strength using a μ-Tas® (MT-1; Anima, Japan). Statistical analyses were performed Pearson's product moment correlation coefficient. [Results] A significant relationship between muscle strength and active balance were observed. Individuals who have high muscle strength and short times to peak torque possess a high capacity of balance and of learning improved postural control. [Conclusion] Static balance may not be a predictor of falls due to low levels of body sway secondary to generally poor ROM seen in elderly individuals.
