Which behavior is NOT indicative of impaired performance in the One Leg Stand test?

Completing the stand without assistance indicates that an individual is able to maintain their balance effectively and does not exhibit signs of impairment during the One Leg Stand test. This behavior suggests that the person has the physical coordination and stability necessary to perform the task successfully, which is a key indication of unimpaired performance.

In contrast, the other behaviors listed—using arms for balance, swaying while balancing, and putting the foot down—are all actions that reflect difficulties in maintaining balance and control, thereby signaling potential impairment. The test is designed to assess an individual’s ability to concentrate and maintain stability, and successfully completing the stand without any need for assistance directly supports the conclusion of normal performance.
