What are the normal limits of stability in degrees for anterior-posterior and lateral movements?

The correct choice reflects the typical ranges of stability for an individual's center of mass during balance activities. In the context of anterior-posterior (forward-backward) and lateral (side-to-side) movements, normal limits of stability are essential for understanding how patients, especially older adults, maintain balance and prevent falls.

Research has shown that the normal limits of stability during these movements are approximately 12.5 degrees for the anterior-posterior direction and 16 degrees for lateral movements. This understanding helps physical therapists assess balance and design interventions tailored to improve stability in older adults, an important aspect of geriatric physical therapy.

By knowing these specific angles, clinicians can better evaluate a patient's balance capabilities and create targeted rehabilitation strategies that address issues related to instability and risk of falls. Ensuring patients reach or maintain these limits is crucial for enhancing their functional independence and overall quality of life.
