Background and purpose: Although tests of standing balance are frequently included in neurological evaluations, few objective data are available to indicate how well individuals of different ages should be able to maintain standing balance. The purpose of this study was: (1) to establish the relationship between performance on timed balance tests and age, and (2) to provide data for use in clinical assessments of patients from 20 – 69 years of age. Subjects: Normal males and females (n=75) in the age group of 20-79 yrs were included in the study after they gave their informed consent. Methods: The subjects were allocated to the five groups according to their age Group A (20-29 years), Group B (30-39 years), Group C (40-49 years), Group D (50-59 years) and Group E (60-69 years). The subject stood without shoes with weight bearing lower extremities inside 18- by 20- inches frame on a smooth and level surface. Subjects in each age group performed eight balancing activities and time was recorded for each activity on a digital stop watch. Results: All subjects balanced for 30 seconds with feet 8 inches apart and with feet together both with their eyes open and with their eyes closed. One legged balance activities were not, however, accomplished for 30 seconds by all subjects. A significant negative correlation existed between the age and the time balanced on one leg with eyes open and closed. Conclusion: The duration that individuals are able to maintain standing balance on one leg is highly related to age.
