The center of gravity in a human being is at the center of the pelvis.
The lower the center of gravity, the more stable the body will be.
Advantages of Good Body Mechanics
Decreases possibility of back injury.
Decreases possibility of falls.
Increases work force with decreased energy.
Use good posture when standing. (Check your posture by standing with heels, shoulders, and head against the wall.)
Stand with feet slightly apart and toes pointed straight ahead.
Sit with your back completely against the back of the chair.
Change position frequently if sitting for a long time.
Walk with feet parallel and close together.
Take a step by pushing off with the back foot.
Swing arms easily as you walk.
Sleep on a firm mattress.
Lying position provides the least pressure on the back.
Lift objects by flexing knees and hips and placing one foot in front of the other one.
Keep load of weight close to the body to keep the balance centered.
Spread feet for a support base and to decrease the possibility of falling.
Use mechanical lifting aids whenever possible, such as a lever, hydraulic lifts, etc.
Use leg muscles instead of back muscles whenever possible.
Bend at the knees rather than at the waist.
Slide objects in smooth, continuous movements whenever possible rather than lifting.
Avoid lifting whenever possible. (Move objects by rolling, turning, etc.).
Push objects rather than pull.
Always carry the weight close to the body.
Use wheels to move objects instead of carrying.
Avoid twisting the spine by pivoting.
Place one foot in front of the other.
Raise heels slightly, placing weight on the balls of the feet to turn 90 degrees.
Face the direction of movement to prevent twisting of the spine.
Stoop with knees and hips flexed to avoid back strain.
Avoid bending with legs straight.
Keep work materials at appropriate level to avoid bending the back.
