balance tests

Quick Reference

Methods of evaluating the ability to maintain a stable equilibrium. One of the simplest involves testing the subject's ability to stand still on 2 feet with eyes open or closed. This may be combined with an ataxiameter, which quantifies head movements. More elaborate tests include the stick-lengthwise test in which the subject stands with the ball of the foot on a stick measuring 1 × 1 × 12 inches (2.54 × 2.54 × 30.5 cm). Some investigators increase the difficulty of the test by raising the stick above the floor. In addition to these tests, teeter boards are often used to measure static balance.
