Study Notes

Body Mechanics Overview

Body mechanics, or ergonomics, ensures safe and efficient patient handling to prevent injury for both patients and nurses.
Utilizes correct muscle groups to execute tasks without excess strain on muscles or joints.
Emphasizes body alignment, balance, and coordinated movements for optimal function.

Importance of Body Mechanics

Essential for performing patient care activities, including pushing, pulling, lifting, and carrying.
Reduces the risk of musculoskeletal injuries and fatigue in nursing staff.
Enables nurses to assist patients in adopting proper body mechanics during movement.

Basic Principles of Body Mechanics

Easier to push, pull, or roll objects than to lift them directly.
Proximity to objects minimizes effort; lifting from close range is advised.
Emphasizes using the stronger muscles in the legs and arms frequently.
Facing the direction of movement prevents harmful twisting of the spine.

Principles of Good Body Mechanics

Stable Center of Gravity: Keep the center of gravity low around the pelvic area; maintain a straight back and bend at the knees and hips.
Wide Base of Support: Provides stability; keep feet apart with one foot slightly forward and flex knees to absorb shocks.
Maintain Line of Gravity: Ensure vertical alignment through the base of support; keep the lifted object close to the body.
Proper Body Alignment: Straighten back, tuck in buttocks, pull in the abdomen, and keep head and chin aligned.

Techniques for Lifting and Reaching

Lifting: Engage leg muscles; bend knees and hips; lift straight upward in one smooth motion.
Reaching: Stand close to the object; avoid twisting; use ladders or stools for high items; maintain a stable base.

Pivoting and Avoiding Stooping

Pivoting: Shift weight by placing one foot ahead; turn both feet simultaneously while maintaining balance.
Avoiding Stooping: Squat using hips and knees instead of bending at the waist; utilize leg muscles to rise back up.

Key Concepts in Body Mechanics

Centre of Gravity: The point where mass is equally distributed; crucial in lifting and support.
Base of Support: The area beneath a person that supports their weight; stability is maximized with a wide base.

Considerations for Physical Tasks

Pulling, pushing, or rolling requires less effort than lifting.
Movements should be smooth and coordinated to prevent injury.
Maintaining motion is easier than starting and stopping objects.
Prioritize using arm and leg muscles over back muscles to reduce strain.
