PostureHow body parts are arranged in relation to each other

Mvt Studies 2011-12

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

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

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

Poor postural habit Psychological factors

Mvt Studies 2011-12

Pain leading to avoidance posture Muscle spasm/imbalance/contracture

Normal developmental process Normal degenerative process

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 2011-12

» What did you identify from your observations?

» Did you identify any difficulties in carrying out your observations?

Mvt Studies 2011-12

» Lets construct a check list system……….

» Anterior view

» Lateral

» Posterior

= Imaginary point where the total weight of a material body may be thought to be

concentrated.

Mvt Studies 2011-12

Mvt Studies 2011-12

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 gravity

Mvt Studies 2011-12

Standing – body alignment

a. Lateral viewb. 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 2011-12

Mvt Studies 2011-12

• 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 2011-12

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

Mvt Studies 2011-12

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

Mvt Studies 2011-12

» Lumbar lordosis flattened» Pelvis is neutral or in

posterior tilt» Hip relatively extended» Line of gravity passes

posterior to hip

Mvt Studies 2011-12

» Forward sway of pelvis» Line of gravity posterior to

hip» Relative hip extension» Thoracic kyphosis

increased in length

Mvt Studies 2011-12

Kyphosis-Lordosis

•Pelvis tilted anteriorly•Hips relatively flexed•Increased lumbar lordosis•Increased thoracic kyphosis

Mvt Studies 2011-12

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

Mvt Studies 2011-12

» 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’)

Why is it important for physiotherapists to observe posture?

Mvt Studies 2011-12

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
