Evaluation of balance during activities of daily living

The skill of balance is essential for activities of daily living. Through the use of a triaxial accelerometer and a portable data logger the skill of balance can be ilssessed during: quiet standing, walking, ascending steps, descending steps, sitting-down in a chair, and standing-up from a chair. Results are reported as performance punmeters. Comparing the results obtained by the same control subject before and after a time comparable to that of a therapeutic intervention, paired Student t tests show consistency over time but significant changes under different test conditions in the same session.
