What is the expected outcome when a person fails the One-Leg Stand test?

The One-Leg Stand test is designed to assess a person's balance and ability to follow instructions while under the influence of alcohol or drugs. When a person fails this test, they typically exhibit signs of swaying or using their arms for support to maintain balance. This behavior indicates that their sensorimotor skills are impaired, which is a common effect of alcohol consumption.

Maintaining balance without difficulty would indicate the person is not impaired, which is not the expected outcome for someone who fails this test. Similarly, stepping off the line may represent a lack of precision in following the instructions; however, the swaying or reliance on arm movement is a more direct indicator of balance issues. Finally, stopping at the designated point suggests successful completion of the task, again contradicting the idea of failure. Therefore, the behavior of swaying or using arms for support is a clear indicator of impairment and is the expected outcome when the One-Leg Stand test is failed.
