What is considered a sign of impairment in the One-Leg Stand test?

The One-Leg Stand test is designed to assess a person's balance and ability to follow instructions while standing on one leg. A sign of impairment during this test is the presence of swaying, hopping, or the use of arms for balance. These behaviors indicate difficulty in maintaining stability, which is a strong indicator that the individual may be impaired.

When a person is unable to keep their balance without assistance from their arms or without moving around, it suggests that their motor skills and coordination are compromised, often due to intoxication or another form of impairment.

In contrast, keeping both feet grounded would actually reflect stability and balance, which is not indicative of impairment. Consistently counting is part of the instructions but does not signify impairment. Lastly, balancing on the opposite leg would not be applicable as it does not pertain to the specifics of the One-Leg Stand test. Thus, the presence of swaying, hopping, or arm usage clearly highlights an inability to perform the task as required, hence signifying possible impairment.
