Lecture 3 - Posture ax Flashcards
What is a “correct posture”
“Position in which minimum stress is placed upon each joints”
What is a “faulty position”
“Any static position that increases the stress to joints”
Primary curves at birth (1)
Concave forward (kyphotic) - thoracic
Secondary curves (2)
Cervical lordosis - extended (heads up)
Lumbar lordosis - extended (sitting, walking)
Anterior plumb line (5)
Nose
Sternum
Xyphoid process
Umbilicus
Pubic symphysis
Posterior plumb line
All spinous processes down to the sacrum
Side plumb line (5)
External acoustic meatus
AC joint
Greater trochanter
Lateral condyle
Lateral malleolus
Two causes of poor posture
Postural (positional) OR structural factors
Anatomical factors affecting posture (7)
Bone contours
Laxity of ligament
Fascial/muscle tightness
Muscle tonus
Pelvic angle
Joint position and mobility
Neurogenic causes
Structural factors affecting posture (4)
Congenital issues
Developmental
Scoliosis
Disc trauma/diseases
Non-structural factors affecting posture (4)
Repeated positioning
Muscle (weakness, inflexibility, etc.)
Pain
Respiratory issues
Abnormal exaggeration of lumbar curve OR excessive anterior curve at lumbar
Lordosis
Causes of lordosis (4)
Congenital deformities
Weak abdominal musculature
Poor posture
Activities with excessive hyperextension
Characteristics of swayback (5)
Anterior pelvis causing hip extension (posterior tilt)
Lordosis is reduced (flexion)
Increased kyphosis (long)
Knees hyperextended
Forward head
Characteristics of kyphosis (4)
Excessive curve of thoracic spine
Congenital
Idiopathic
Secondary to osteoporosis
