What does a raised arm indicate during the Walk-and-Turn test?

During the Walk-and-Turn test, a raised arm typically indicates balance issues. This test is designed to evaluate a person's ability to maintain balance while walking in a straight line and then returning. The test requires the individual to perform a series of tasks, including walking heel-to-toe and then turning around. If a subject raises their arm during this process, it is generally a sign that they are struggling to maintain their balance, which can be an indicator of impairment.

Maintaining proper balance is crucial for successfully completing the test, and raising an arm is a compensatory action that reflects difficulty. The expectation is that a sober individual should be able to complete the test without needing to use their arms for balance. Thus, a raised arm is a significant observation during the test that suggests potential impairment.
