Balance, the ability to maintain the center of gravity over the base of support within a given sensory environment, is composed of several subcomponents and influenced by several systems (sensory, musculoskeletal, and central and peripheral nervous systems). The assessment and management of balance and posture in brain disorders are complex. To make a reasonable choice about balance scales to use, it is important to understand the balance system, to have a careful understanding about measurement tools in brain disorders and have a comprehensive way to assess balance function and dysfunction. This is a challenge for balance activity measurement tools as the most balance scales needs underlying theoretical approach behind the clinical assessment. Further research is needed to develop the theoretical construct with ecological validity, the 'hierarchy' conceptual scale and combine the individual test to the patients' level of balance ability. And assessment of the minimum detectable change in each test should be included and paid attention that is vital for clinical interpretation of scores. In conclusion, a thorough assessment into the cause of balance dysfunction in brain disorders is essential to the implementation of appropriate treatment, usually a multidisciplinary approach.
