Which of the following is a clue observed during the One-Leg Stand test?

• A. Stops moving instantly
• B. Speaks clearly
• C. Smiles frequently
• D. Sways while balancing

Answer: (D)

The clue observed during the One-Leg Stand is swaying while balancing. This test gauges balance and motor control, which are affected by impairment such as intoxication. When someone shows a wobble or instability while standing on one leg, it indicates difficulty maintaining steady posture, a hallmark the test looks for.

The other options don’t reflect typical indicators of impairment in this specific test. Stopping movement instantly isn’t a standard cue of impairment because finishing the stance doesn’t reveal how well balance was maintained. Speaking clearly suggests preserved cognitive and motor coordination, which argues against impairment in the context of this test. Smiling frequently isn’t a recognized cue for balance or coordination problems during the One-Leg Stand. Thus, swaying while balancing best fits what the test aims to observe.
