Trunk and Shoulder Flashcards
what are the primary spinal curvatures?
thoracic and sacrococcygeal kyphosis
what are the secondary spinal curvatures?
cervical and lumbar lordosis
what is the foundation of all head, neck, and limb movement?
trunk control
what is optimal alignment?
Anterior pelvic tilt
Lumbar extension
Thoracic extension
Cervical extension
what is the foundation of optimal alignment?
pelvic position
type of contraction: muscle contracts and gets shorter
concentric
type of contraction: muscle is engaged and lengthens
eccentric
Normal control requires the ability to dissociate (separate) different parts of the body from each other
dynamic dissociation
what does posterior pelvic tilt lead to?
lumbar flexion→ thoracic flexion→ scapular abduction→ humerus internal rotation
what does anterior pelvic tilt lead to?
lumbar extension→ thoracic extension→ scapular adduction→ humerus external rotation
what is the foundation for everything that happens in the UL?
scapula
what can we do in therapy for lower cervical flexion, upper cervical hyper extension?
wedge stretch
what is the normal position of the scapula?
30-40 degrees internal rotation
30 degree point between flexion and abduction
scaption
what is the normal ratio for scapulohumeral rhythm?
2 parts humeral movement to 1 part scapular movement
with what condition is scapulohumeral rhythm affected?
hemiplegia
with hemiplegia, why is harm done when passive ROM at 90 degrees shoulder flexion or above?
scapulohumeral rhythm is off
which are stronger? shoulder IR or shoulder ER?
shoulder IR
which are stronger? shoulder Flex or shoulder Ext?
shoulder Ext
which are stronger? shoulder ADD or should ABD?
shoulder ADD
