Principles of body mechanics

The document discusses principles of body mechanics. It defines body mechanics as the efficient, coordinated, and safe use of the body to move objects and perform activities of daily living. Maintaining proper body mechanics is important to reduce injuries, fatigue, and strain when performing physical tasks. Key principles include keeping the body stable with a wide base of support and low center of gravity, as well as dividing tasks between the arms and legs and avoiding jerky movements.

Principles of body mechanics By Mr. M. Shivanandha Reddy
INTRODUCTION Some of the most common injuries sustained by members of the health care team are severe musculoskeletal strains. Many injuries can be avoided by the conscious use of proper body mechanics when performing physical work.
DEFINITION Body mechanics the term used to describe the efficient, coordinated, and safe use of the body to move objects and carry out the Activities of Daily Living (ADL’s).
PURPOSES • To maintain good balance. • To reduce the energy required. • To avoid excessive fatigue. • To avoid muscle strains or tears. • To avoid skeletal injuries. • To avoid injury to the patient. • To avoid injury to assisting staff members
Principles of Body Mechanics • The wider the base of support, the greater the stability. • The lower the centre of gravity, the greater the stability. • The equilibrium of an object is maintained as long as the line of gravity passes through its base of support.
Principles of Body Mechanics •Facing the direction of movement prevents abnormal twisting of the spine.
Principles of Body Mechanics • Dividing balanced activity between arms and legs reduces the risk of back injury. •It is easier to pull, push, or roll an object than it is to lift it . •Movements should be smooth and coordinated rather than jerky
Principles of Body Mechanics •When friction is reduced between the object to be moved and the surface on which it is moved, less force is required to move it. •Less energy or force is required to keep an object moving than it is to start and stop it. •Use the arm and leg muscles as much as possible, the back muscles as little as possible
Principles of Body Mechanics • Keep the work as close as possible to your body. It puts less of a strain on your back, legs, and arms • Keep the work at a comfortable height to avoid excessive bending at the waist. • Keep your body in good physical condition to reduce the chance of injury.
Principles of Body Mechanics • Rest between periods of work promotes work endurance
