Body Mechanics

Why is proper body mechanics and posture an important factor? Body mechanics and posture work together to prevent injury and illness. Having poor body mechanics when lifting/moving things increases the risk of back pain. A benefit of having proper posture and body mechanics requires less energy to maintain a state of balance. Proper posture includes keeping your body centered over the base of support in regards to line of gravity when this is disturbed the individual increases risk of falling or injuring ones self. Proper posture and movement helps the body reduce stress applied to the spine and does not strain the body's muscles and ligaments. Posture is also involved in joint function and when the alignment is off it causes stress and the degeneration of different joints. Another factor associated to poor posture is a more difficult time breathing, if the body has proper posture the chest is able to expand. It is important to teach good body mechanics and posture to individuals because they are reducing their risk of injury, illnesses, and joint and muscle damage while increasing the spines stability. 

During an intervention of teaching a client body mechanics and posture the first thing I would do would be to have the client stand against the wall if possible to explain correct body posture. While against the wall the client needs to have their heels to the back of the wall, the shoulders against the wall, with the chin tucked and head down while against the wall as well to demonstrate proper posture. I could even have the client show me what they think correct posture is to them and correct where necessary. Next to assess body mechanics I will get the client to make sure they have their feet placed shoulder width apart or large enough to have a good base of support. Reminding the client that when lowering down to grab something and lift back up to bend at the hips and knees and not at the waist which stresses the back. They also may need to be reminded that when using proper body mechanics the neck pelvis and back should all be aligned remembering not to twist at the waist, which will cause back pain and or injury. Lift with the legs and arm muscles not your back and keep the object close to was it level. The client can practice this while using a stick placed on their back to make sure their alignment is correct or they can perform an activity while the therapist observes and corrects their posture.
