In the One-Leg Stand SFST, what does "P" stand for in the acronym PUSH?

In the context of the One-Leg Stand test, "P" in the acronym PUSH stands for "Puts foot down." This reference is essential as it signifies one of the indicators of impairment when a subject fails to maintain their balance on one leg. During the test, the participant is instructed to stand on one leg for a certain period while counting out loud. If they put their foot down, it reflects an inability to maintain balance, which can be a strong indicator of impairment. This action is one of the specific criteria used by law enforcement to assess a person's level of intoxication.

The other options do not accurately represent what "P" stands for in the context of this test. While prolonged duration, perceived instability, and pressure on the ground might relate to balance or stability, they do not describe a direct action that participants may take during the One-Leg Stand task. Recognizing that "P" means "Puts foot down" allows for a clearer understanding of how this behavior plays into the assessment of sobriety during the SFST.
