What response indicates a clear inability to perform the Walk and Turn task effectively?

Using arms for balance during the Walk and Turn task is a significant indicator of difficulty and lack of coordination. This task is designed to assess a person’s ability to maintain balance and perform simple tasks in a controlled manner. When an individual resorts to using their arms for balance, it suggests they are unable to stabilize themselves adequately while walking in a straight line and executing turns as instructed.

This behavior reflects a lack of stability and control, which is a critical component being evaluated in this task. The use of arms indicates the individual is struggling to maintain their balance merely by walking heel-to-toe, which is a demonstration of the skill and coordination that is expected during the task. In contexts like sobriety tests, this is a clear sign that the individual may exhibit impaired motor functions.

In contrast, the other responses, such as taking long steps, pausing mid-task, or skipping steps, can occur for a variety of reasons and may not directly indicate the same level of imbalance or impairment. For example, long steps can sometimes indicate a way of compensating for balance but do not inherently suggest a clear inability to perform the task. Similarly, pausing could be due to a person thinking through the instructions or trying to maintain composure, and skipping steps may
