Postural adjustments refer to the body's ability to maintain balance and stability by changing its position in response to various stimuli. These adjustments are crucial for activities like walking, standing, and sitting, as they help prevent falls and injuries. The body uses sensory information from the eyes, inner ear, and muscles to make these adjustments. When a person encounters an unexpected change, such as a slip or a shift in weight, postural adjustments occur automatically. The nervous system plays a key role in coordinating these responses, allowing the body to quickly adapt and regain balance. This process is essential for everyday movements and overall physical health.
