What aspect of the subject is assessed during the One Leg Stand test?

The One Leg Stand test primarily assesses balance. During this field sobriety test, the individual is asked to stand on one leg for a set amount of time, typically 30 seconds, while keeping the other leg raised. Maintaining balance in this position requires a stable center of gravity and coordination of muscle groups. Impairment can lead to difficulty in holding the position, indicating a potential influence of alcohol or other substances.

While coordination can also play a role in maintaining balance, the test is primarily focused on evaluating the individual's ability to remain stable in a one-legged position. The other options, such as general health and strength, are not directly measured by this particular test but may be relevant in broader assessments of fitness or impairment.
