What is NOT a clue of impairment in the instruction phase of the one leg stand test?

In the one leg stand test, various clues indicate a person's level of impairment, particularly focusing on their ability to balance on one leg without assistance. Starting too late is not considered a clue of impairment because it relates to the timing of the participant's response rather than their physical or cognitive ability to complete the test correctly. The other options—putting the foot down, using arms for balance, and jumping to maintain balance—are specific actions that directly indicate difficulties in maintaining stability and indicate a possible level of impairment.

These actions suggest that the individual may have impaired motor skills or difficulties with coordination, which are key indicators of physical impairment. Therefore, the act of starting late does not fall under the same category as the other observed behaviors during the test.
