Which of the following is NOT a principle of biomechanics when moving and positioning an individual?

The principle of biomechanics emphasizes optimal movement and positioning techniques to promote safety and efficiency, particularly in manual handling. When considering the correct answer, leaning in towards the most comfortable side is not a recognized biomechanical principle. Instead, effective manual handling focuses on maintaining a stable center of gravity, utilizing the body's strength for lifting, and ensuring that the load is balanced over the feet.

Maintaining a stable center of gravity is crucial for balance and stability during movements, reducing the risk of injury. Using the body's strength leverages the natural capabilities of muscles, promoting safer lifting techniques. Balancing the load over the feet distributes weight evenly and supports proper posture, further preventing strain. By contrast, leaning towards one side can result in an unbalanced load and increase the likelihood of accidents or injuries.
