How body parts are arranged in relation to each other Mvt Studies

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 Mvt Studies

» In pairs, make a list of the factors that may alter your posture.

» Permanent anatomical deformities not amenable to correction by conservative treatments. Mvt Studies

Poor postural habitPsychological factors Mvt Studies

Pain leading to avoidance posture Muscle spasm/imbalance/contracture Mvt Studies

Normal developmental process Normal degenerative process Mvt Studies

Physiological mechanisms – visual, vestibular Respiratory conditions Mvt Studies

Excess weightPhysical Build Mvt Studies

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 Mvt Studies

» What did you identify from your observations? » Did you identify any difficulties in carrying out your observations? Mvt Studies

» Lets construct a check list system………. » Anterior view » Lateral » Posterior Mvt Studies

= Imaginary point where the total weight of a material body may be thought to be concentrated. Mvt Studies

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?

» 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 gravitycentre of gravity Mvt Studies

a.Lateral view b.Posterior view Line of gravity starting at the mastoid process falls through or just in front of all the main weight bearing joints Mvt Studies

In groups of 3 observe each others posture again, using a plumb line, consider where body segments are in relation to LoG » Make a note of what you observe, referring back to your ‘check list’.

» What did you observe this time? » How many of you had an ‘ideal’ postural alignment? Mvt Studies

˃How is your weight distributed? ˃Can you detect any postural sway? Mvt Studies

» Ideal » Flat back » Sway back » Kyphosis-lordosis Mvt Studies

» Lumbar lordosis flattened » Pelvis is neutral or in posterior tilt » Hip relatively extended » Line of gravity passes posterior to hip Mvt Studies

» Forward sway of pelvis » Line of gravity posterior to hip » Relative hip extension » Thoracic kyphosis increased in length Mvt Studies

Pelvis tilted anteriorly Hips relatively flexed Increased lumbar lordosis Increased thoracic kyphosis Mvt Studies

» Look at each others postures again and see if your model fits one of these postural types Mvt Studies

» 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’) Mvt Studies

Why is it important for physiotherapists to observe posture? Mvt Studies
