2 Why is this Important to you? Health care providers must know how to properly apply the principles of body mechanics to minimize personal and client injuryThe number of injuries in health care facilities related to improper use of body mechanics has risen over the yearsWhy is this Important to you?
3 Types of Levers in the Body First Class LeverHead being tipped backward on the atlasThe facial portion of the skull is the load, the joint between the skull and the atlas is the fulcrum, and muscles of the back produce the pullTypes of Levers in the Body
4 Types of Levers in the Body Second Class LeverRaising the body on the toesThe point of contact between the toes and the ground is the fulcrum, the load is located at the ankle, and the pull is exerted at the gastrocnemius (the muscle in the calf)Types of Levers in the Body
5 Types of Levers in the Body Third Class LeverFlexing of the forearm at the elbow joint as in lifting a hand weightThe load is the weight in the hand, the pull is the biceps brachii muscle, and the fulcrum is the elbow.This is the most common lever in the bodyTypes of Levers in the Body
6 Principles of Body Mechanics Use the larger and stronger muscles to perform workWhen moving heavy objects, push or pull instead of liftingGet help!Maintain good postureBack straightKnees bentWeight evenly distributed on both feetFeet shoulder width apart (about 12 inches)Avoid twisting your whole bodyKeep objects close to your body when listing or carryingAvoid unnecessary bendingPrinciples of Body Mechanics
7 When should you use body mechanics? You should use proper body mechanics at all times!In everyday activity such as carrying your schools books, getting in or out of your car, moving a chairIn health care setting such as when moving a patient to or from a chair, picking up supplies, or positioning a patient in bedWhen should you use body mechanics?
8 Ergonomics Ergonomics: the science of work Fit the work to the user instead of forcing the user to the workOSHA has developed a policy of “no lifting” in Long Term Care Facilities and other high risk areasErgonomics

10 Range of Motion: the complete extent of movement of which a joint is capable
11 Range of Motion Active Range of Motion Movements performed by the patient without helpRange of Motion
12 Range of Motion Passive Range of Motion Movement cannot be performed by the patient and the health care worker moves each join through its range of motionRange of Motion
13 Range of Motion Active Assistive Range of Motion The patient does the exercises with some assistance from another personRange of Motion
