What is the second phase of the one leg stand test?

The second phase of the one leg stand test is counting and balancing. In this phase, the subject is instructed to stand on one leg and count out loud by thousands (e.g., "one thousand one, one thousand two," etc.) while maintaining their balance. This part of the test is crucial as it assesses both the subject's ability to balance and their cognitive function, as they must perform a physical task while also concentrating on counting. It is designed to evaluate the coordination and stability of the individual, which can be impacted by impairment from substances or other factors.

The other phases have distinct purposes; instructions involve explaining how the test will be administered, the observation phase serves to monitor the subject's performance and behavior during the test, and the final assessment is typically where the officer evaluates the overall results and determines whether any impairment is present.
