How to measure changes in mobility among older adults with psychometrically defined mild cognitive impairment?

Thank you.

My heartfelt thanks.

To measure changes in mobility among older adults with mild cognitive impairment (MCI):

Conduct the Timed Up and Go (TUG) test, which evaluates the time taken to stand up from a chair, walk 3 meters, turn around, walk back, and sit down. The TUG is a sensitive and specific measure of fall risk in older adults with MCI.

Stratify TUG scores based on cognitive status (with and without MCI), gender, and age groups to establish normative data and detect meaningful differences.

Observe postural stability, gait, stride length, and sway during the TUG to identify neurological problems requiring further evaluation.

Repeat the TUG at regular intervals to monitor changes in mobility over time and assess the effectiveness of interventions.
