Postural Assessment Flashcards
Position in which minimum stress is applied to each joint
Correct posture
Any static position that increases the stress on the joints.
Faulty posture
Primary curves
Kyphosis (Thoracic & Sacral)
Secondary curves
Lordosis (Lumbar & Cervical)
Center of Gravity
5 in. anterior to s2
T12 (for babies)
COG for head
Sphenoid sinus
COG for head & neck
Bassioccipital
COG for head, neck, & trunk
Anterior to T11
COG for UE
Just above the elbow
COG for arms
Medial head of the triceps
COG for forearm
Pronator teres
COG for hand
3rd MCP
COG for LE
Just above the knee joint
COG for thigh
Adductor brevis
COG for leg
Popliteus
COG for foot
2nd MTT
The area within the points of contact of the body and any object individual relies on for support
Base of Support (BOS)
And imaginary vertical line that passes from the COG to the ground or surface the object or person is on.
Line of Gravity (LOG)
Line of Gravity for UE
Through Odontoid process
Anterior to AO joint
Through Cervical spine
Anterior Thoracic spine
Through Lumbar spine
Line of Gravity for LE
Posterior to Hips
Anterior to the knee
Anterior to the ankle
When the LOG is within the BOS
Stable
When the LOG falls outside of the BOS
Unstable
How to increase stability
Larger BOS
Lower COG
Anatomical factors affecting correct posture
Bony contours
Laxity of ligamentous structures
Muscle tonus
Pelvic angle
Joint position and mobility
Normal pelvic angle
30 degrees
Upper cross body syndrome
Tight upper traps & LS
Weak deep neck flexors
Weak lower and mid traps & serratus
Tight Pecs
Lower cross body syndrome
Tight Erector spinae
Weak Abdominals
Tight Iliopsoas
Weak Gluteus Maximus
Causes of poor posture
Postural (Positional) factors
Structural factors
Postural (Positional) factors
Poor postural habits
Early growth spurt
Muscle imbalance
