True
False
There are 4 curves
They are anterior-posterior (AP)
They provide the vertebral column w/ more strength and resilience
It is 10X stronger than if a straight rod

Orthotics
Taping
Photographs/mirrors for feedback
Increased flexion of lower cervical/upper thoracic region/ Increased ext of capital extension
Plumb line posterior to lumbar bodies
Protracted scapulae
Lengthened abdominals
>30 degrees of lumbosacral angle
Lengthened hip flexors
Shortened lumbar extensors
Lengthened abdominals
Posterior pelvic tilt
Approximation of lumbar facets/narrowing of intervertebral space
Plumb line significantly anterior to thoracic vertebrae
Protracted scapulae
Lengthened pectorals, intercostals & scapular protractors/upward rotators
Often accompanies increased lumbar lordosis
Lengthened thoracic spinal extensors, scapular retractors/downward rotators
Entire pelvic segment shifted posteriorly
Hip extension, thorax shifted posteriorly, Usually forward head
Shortened upper abs, intercostals, hip extensors & lumbar extensors
Lengthened lower abs, thoracic extensors & hip flexors
Decreased lumbosacral angle
Hip extension
Anterior pelvic tilt
Lengthened trunk flexors/hip extensors
Lengthened lumbar extensors & possibly hip flexors
Decreased thoracic kyphosis
Depressed scapulae/ Clavicle/ and decreased cervical lordosis
Lengthened thoracic extensor & scapular retractors
Lengthened scapular protractors & intercostals
