Analysis of posture Flashcards
What is posture?
posture Is the composite Of positions All joints at any given time
The primary curves
thoracic And sacral
Secondary curves
Cervical and lumbar
What are the causes for bad posture
Pain
fatigue
Bad habits and
neuromusculoskeletal defects
Standard posture
- Normal Curves
- Bones of lower extremities are in ideal alignment
- Normal pelvis posture: In alignment with the trunk and abdomen
- Chest an upper body in optimal position for  Respiratory function
- Head erect in comfortable positions 
Plumbline
Represents A line of reference
An ideal plumbline
- Through the earlobe
- Through the body of the cervical vertebra
- Through the shoulder joint
- Proximately midway through your trunk
- Approximately through your greater trochanter
- Slightly anterior to the midline of the knee
- Slightly anterior to the midline of the lateral malleolus this
Poor posture
Cause Any deviation From ideally aligned erect posture
Poor posture may cause
Secondary deformities
Fatiguability high energy expenditure
Pain
Physiological disturbance
Cosmetic appearance
4 Types of postures
- Lordosis
- Kyphosis
- Flat back
- Sway back
Lordosis
normal inward curvature of the spine.
When this curve is exaggerated it is usually
referred to as hyperlordosis.
Pelvis tilted anterior
kyphosis
An increased convex curve
observed in the thoracic or sacral regions of
flat back
there is forward head, extension of the
cervical spine, extension of the thoracic
spine, loss of lumbar lordosis and posterior
pelvic tilt.
Sway back
there is forward head, hyper-extension of
the cervical spine, flexion of the thoracic
spine, lumbar spine extension, posterior tilt
of the pelvis, hip and knee hyper-extension
and ankle slightly plantarflexed.
anterior Pelvic tilt
distance between the angle between the pelvis and thigh anteriorly decreases
posterior pelvic tilt
Hips extend and the lower back flattens
