Introduction: Balance is a complex form of related physiological systems: sensory, central nervous and nervous-muscular systems. There are few factors that influences balance: biomechanical constraints, movement strategies, sensory strategies, orientation in space, control of dynamics and cognitive processing. In order to assess the quantity of balance, one or more component tests are being used. Balance outcome measure for elder rehabilitation is a general balance test used for elder rehabilitation. It consists of more single-component tests: Step test, Timed up and go test, Functional reach test and Timed static stance feet together eyes closed test. The Balance outcome measure for elder rehabilitation is designed to assess the three main components of balance: functional stability limits, underlying motor system, anticipatory postural control, dynamic stability and sensory integration. Aim: To investigate whether the Balance outcome measure for elder rehabilitation rating scale is appropriate for balance assessment of fit elderly. Method of use: 26 fit elderly were tested by Balance outcome measure for elder rehabilitation rating scale. Their results have been analyzed by program SPSS. Results: 17 participants (65.4%) scored maximum number of points (16) on Balance outcome measure for elder rehabilitation scale, 8 participants (30.8%) scored 15 points. We are suggesting adding an additional level on the scale can change its measuring properties. 4 participants (15.4%) scored maximum number of points (29) on extended scale for one level. Discussion and conclusion: The results have shown that fit elderly reach the ceiling effect on Balance outcome measure for elder rehabilitation rating scale. Therefore, the traditional rating scale is not appropriate for assessment of fit elderly. If the scale is extended for one level, the data is distributed too close to normal distribution. Data is distributed in distribution similar to standard normal after adding additional level on the scale, but results reach ceiling effect. Additional studies are necessary to evaluate if the new scale is suitable for assessing balance of fit elderly.
