Improper lifting technique is often a primary cause of back strain and injury. A back injury caused by lifting may result in 1 or more of these problems:
Muscle injury. Stress on the lower back muscles can happen when you get out of proper position while lifting. Too much stress on the muscles can cause strain, pull, or small tears.
Disk injury. A disk is a type of cushion between the bones of the spine. A back injury can cause a disk to bulge or rupture and then press on 1 or more nerves to cause pain and discomfort.
Joint injury. This type of injury can happen when you use improper lifting methods, even when the item you're lifting is relatively light.
The following tips can help avoid injury when lifting objects:
Face the object you want to lift and, with your back straight, lower yourself to the floor and bend 1 knee with the other foot flat on the floor.
Tilt the object to 1 side, if possible, so it can be lifted from underneath.
Keep the object close to your body.
Support your back by tightening and holding in your belly muscles.
Use your arms, legs, and buttocks to lift the object. Don't twist, and don't use your back.
Keep a firm grip on the load, and keep your arms and elbows close to the body while lifting.
When carrying the load, keep it close to your body. Don't twist your back. Keep your shoulders and hips in line with each other. When changing direction, shift the position of your feet and turn your entire body.
When you're ready to set the load down, bend your knees to lower it rather than bending at the waist. If the object is to be placed on a shelf, bench, or table, set it on the edge of the shelf (or bench or table) and push it into the desired position.
Remember, it's better to ask for help to lift a heavy object than to injure your back.
