See Figure 2. The table below lists common ergonomic injuries of the hands, arms and shoulders. Low back pain occurs due to a variety of injuries and illnesses. Muscles and ligaments in the back can be injured and cause pain. Injuries and illnesses affecting discs and nerves are also very painful.
Discs can deteriorate, or a disc can stick out and press on nerves.
This condition is called a herniated disc , which is sometimes called a slipped disc. Problems with the spinal column can also cause pressure on nerves. Lifting, pulling, pushing, bending and twisting are factors that cause lower back pain. These movements involve the risk factors of force, repetition and harmful posture. Vibration is another condition that can lead to back pain.
