  1. What do the proper use of body mechanics do?
    1. protect self and patient from injury

    2. reduce physiological and anatomical stress and strain to your body

    3. conserves energy

    4. allows you to effectively manage and move equipment, supplies, and patients

    5. form good habits to maintain comfort, ease of movement, and consistency of movement
  2. What are the 4 regions of the spinal column?
    • cervical
    • thoracic
    • lumbar
    • sacral and coccygeal
  3. What 2 regions of the spinal column curve anterior?
    • cervical
    • lumbar
  4. What 2 regions of the spinal column curve posterior?
    • thoracic
    • sacral and coccygeal
  5. What condition causes an increased posterior curve in the thoracic region?
    kyphosis (stuped over)
  6. What condition causes an increased anterior curve of the lumbar region?
  7. What condition causes a lateral curve of the spine?

    *compensatory curve in opposite direction of scoliosis curve
  8. What are the 2 types of articulations joints?
    • fibrocartilagenous
    • synovial
  9. What type of joint is between the vertebral discs?
  10. What type of joint is a facet joint?
  11. What do facet joints do?
    control the amount and direction of movement
  12. What allows flexibility in your spine and acts as a shock absorber?
    disc (jelly-like surrounded by tough rubber-like bands that are attached to the bones)
  13. What is the symphysis between the vertebral bodies?
    intervertebral disc

    *shock absorber
  14. What are the 2 components of intervertebral discs?
    • annulus fibroses - toward outer layer
    • nucleus pulposus - inside; gum-like consistancy
  15. What are the ligaments around the intervertebral symphysis for?
    tough and inelastic for stability
  16. What are the ligaments around the vertebral arch for?
    elastic and stretchable for movement
  17. Extensor muscles are normally located on which side of the body (anterior/posterior)?
  18. Flexor muscles are normally located on which side of the body (anterior/posterior)?
  19. What is the 2 different forced that act in opposite directions to stabilize a body part?
    pelvic force couple
  20. What muscles are included in the pelvic force couple?
    • abdominals - trunk flexors
    • hip flexors - anterior
    • quads - hip flexor, anterior
    • gluteals - posterior
    • hamstrings - posterior
  21. What are the 6 natural causes of back pain?
    • aging
    • disease
    • trauma
    • misuse
    • poor posture and positioning
    • lack of muscle strength and flexibility
  22. How does gravity effect body mechanics?
    exerts downward force on pelvis ->pulls it forward ->increases lumbar lordosis

    *if abdominals are weak or hip flexors are tight, the force of gravity is not counteracted
  23. What are the 5 things to do before lifting, pushing, or pulling something?
    • 1. determine best method
    • 2. path clear and established
    • 3. distance and assistance needed
    • 4. assistants instructed before the move
    • 5. expect the unexpected!!
