During the instruction phase of the one leg stand, what is NOT an indicator of impairment?

Counting backwards is not considered an indicator of impairment during the one leg stand test. This particular test is designed to assess an individual's balance and ability to maintain stability while standing on one leg for a specific duration. The critical indicators of impairment in this scenario typically involve physical actions that reflect difficulties in maintaining stability, such as putting a foot down, using arms to balance excessively, or hopping to regain balance.

In contrast, counting backwards is a cognitive task that does not relate directly to physical balance or stability and is not part of the standard criteria utilized to assess impairment in this test. While cognitive impairments may affect overall driving ability, the one leg stand test specifically focuses on motor skills and physical responses rather than mental processing skills.
