What does the Walk-and-Turn test assess?

The Walk-and-Turn test is specifically designed to assess coordination and balance. During this test, an individual is required to take several steps in a straight line, turn on one foot, and walk back in a straight line. This process highlights the person's ability to maintain balance while performing a series of physical movements, which is critical in evaluating potential impairment due to alcohol or drugs.

The nature of the test requires the subject to focus on both their physical footing and overall body coordination while also following multi-step instructions. Successfully completing the Walk-and-Turn indicates better coordination and balance, both of which can be adversely affected by substances, substantiating its use in sobriety assessments. The focus on these specific motor skills makes coordination and balance the core aspects evaluated in the test.
