Very few people are affected by back pain Back injuries cost employers an estimated $10 billion a year The back is a complex system of bones, discs, muscles and nerves The spine is a straight column of rigid bones The safest way to lift an object is to stand close to it, bending your knees and letting your legs do the work.

  4. Why have Training?? • Second most common injury in the state • Second (only to the common cold) most frequent visit to the doctors office • Statistically, 8 out of 10 will suffer some sort of back pain throughout their life • One of the leading causes of disability and time lost from work • Direct costs estimated at $24 billion, indirect costs reaching $35 billion with a total of nearly $60 billion to the employer

  13. The Force is Against You

  14. The Forces Involved The amount of force you place on your back in lifting may surprise you! Think of your back as a lever. With the fulcrum in the center, it only takes ten pounds of pressure to lift a ten pound object.

  15. The Forces Involved If you shift the fulcrum to one side, it takes much more force to lift the same object. Your waist acts like the fulcrum in a lever system, on a 10:1 ratio. Lifting a ten pound object puts 100 pounds of pressure on your lower back.

  16. The Forces Involved When you add in the 105 pounds of the average human upper torso, you see that lifting a ten pound object actually puts 1,150 pounds of pressure on the lower back.

  17. The Forces Involved If you were 25 pounds overweight, it would add an additional 250 pounds of pressure on your back every time you bend over.

  19. Types of Back Injuries

  20. Back Strain • Definition: Strains are tears or stretches in the muscle fibers or the tendons that connect muscles to bones. Strains can range from relatively mild injuries, with some muscle fibers being torn, to large muscle tears with swelling and bleeding present. • Symptoms/Signs: • Pain, swelling, and tenderness in a muscle group or joint

  21. Back Sprain • Definition: A sprain occurs when a ligament -- the tissue that connects bones together -- is stretched or torn. • Symptoms • joint pain or muscle pain • swelling • discoloration of the skin, especially bruising • impaired joint function

  22. Bulging Disc • A bulging disc appears to have moved or slipped out of place. Discs cant really move, but swelling or years of poor posture can leave them protruding from between the vertebrae. The vertebrae squeeze the bulging disc and cause pain

  23. Herniated Disc • A herniated disc is a rupture of the jelly-like substance from inside one of the fibrous discs that provide cushioning between the vertebrae of the spine. Herniation results in pressure on nearby nerves which can result in a variety of symptoms, depending on the location of the affected disc.
