List three causes of postural defects?

1. Poor posture habits: Slouching, hunching over, or sitting for long periods of time can lead to postural defects over time.

2. Muscle imbalances: Weak or tight muscles in the back, shoulders, and core can cause postural defects as they are unable to properly support the spine and maintain proper alignment.

3. Injury or trauma: Accidents, falls, or other injuries can result in postural defects as the body compensates for pain or limited range of motion in certain areas.
