  1. Analysis of Posture Movement Studies Mvt Studies 2009-10

  2. Mvt Studies 2009-10 Learning Outcomes • Define what is understood by the term posture • Discuss the factors that may influence posture • Begin to analyse standing, sitting and lying postures • Develop a posture check list

  3. Mvt Studies 2009-10 Posture How body parts are arranged in relation to each other

  4. Mvt Studies 2009-10 What is good posture? Allows your body to function at it's best • Minimal strain • on the muscles, ligaments, bones and joints • Organs are not compressed, blood vessels are not pressed, nerves are not irritated. • Minimal energy costs. • Stable and balanced position

  5. Mvt Studies 2009-10

  6. Mvt Studies 2009-10 Posture • In pairs, make a list of the factors that may alter your posture.

  7. Structural Mvt Studies 2009-10 • Permanent anatomical deformities not amenable to correction by conservative treatments.

  8. Mvt Studies 2009-10 Poor postural habit Psychological factors

  9. Mvt Studies 2009-10 Pain leading to avoidance posture Muscle spasm/imbalance/contracture

  10. Mvt Studies 2009-10 Normal developmental process Normal degenerative process

  11. Mvt Studies 2009-10 Physiological mechanisms – visual, vestibular Respiratory conditions

  12. Mvt Studies 2009-10 Excess weight Physical Build

  13. Mvt Studies 2009-10 Focus of the practical Task 1 • In groups of 3 look at each others posture in standing • Make notes of what you see using the correct terminology • Be prepared to feedback your findings

  14. Mvt Studies 2009-10 Feedback • What did you identify from your observations? • Did you identify any difficulties in carrying out your observations?

  15. Mvt Studies 2009-10 Posture check list • Lets construct a check list system………. • Anterior view • Lateral • Posterior

  16. Posture Check ListDid you consider all of the below? Mvt Studies 2009-10

  17. Centre of gravity Mvt Studies 2009-10 = Imaginary point where the total weight of a material body may be thought to be concentrated.

  18. Mvt Studies 2009-10 Consider how the position of the centre of gravity varies in: A child compared to an adult Lying compared to standing What effect does this have on stability?

  19. Mvt Studies 2009-10 Ideal line of gravity • Line of gravity (LoG) An imaginary vertical line passing from the centre of gravity of an object down to the ground. It is also known as the line of action of the force of gravity

  20. Mvt Studies 2009-10 Standing – body alignment Lateral view Posterior view Line of gravity starting at the mastoid process falls through or just in front of all the main weight bearing joints

  21. Mvt Studies 2009-10 Task 2 • In groups of 3 observe each others posture again, consider where body segments are in relation to LoG • Make a note of what you observe, referring back to your ‘check list’.

  22. Mvt Studies 2009-10 Feedback • What did you observe this time? • How many of you had an ‘ideal’ postural alignment?

  23. Mvt Studies 2009-10 What do you notice when you stand still? • How is your weight distributed? • Can you detect any postural sway?

  24. Mvt Studies 2009-10 Different Postural Types • Ideal • Flat back • Sway back • Kyphosis-lordosis

  25. Flat Back Mvt Studies 2009-10 • Lumbar lordosis flattened • Pelvis is neutral or in posterior tilt • Hip relatively extended • Line of gravity passes posterior to hip

  26. Sway Back Mvt Studies 2009-10 • Forward sway of pelvis • Line of gravity posterior to hip • Relative hip extension • Thoracic kyphosis increased in length

  27. Mvt Studies 2009-10 Kyphosis-Lordosis Pelvis tilted anteriorly Hips relatively flexed Increased lumbar lordosis Increased thoracic kyphosis

  28. Mvt Studies 2009-10 Task 3 • Look at each others postures again and see if your model fits one of these postural types

  29. Mvt Studies 2009-10 Task 4 • Observe each others sitting posture in the following cases • A. sitting in a chair • B. sitting on the edge of a bed • C. sitting on the floor (Don’t forget to refer to your ‘posture check list’)

  30. Feedback – What did you observe? Mvt Studies 2009-10

  31. Mvt Studies 2009-10 Why is it important for physiotherapists to observe posture?

  32. Mvt Studies 2009-10 Conclusion Make sure you are happy the learning outcomes have been met: • Define what is understood by the term posture • Discuss the factors that may influence posture • Begin to analyse standing, sitting and lying postures • Develop a posture check list
