Midterm Flashcards
What are the effects of joint mobilization?
Neurphysiological
Biomechanical
Psychological
What are the three sub-systems that contribute to stability in the spine?
passive
active
central nervous system
Passive system:
anatomical structures contributing to stability
Active system:
muscles, source of active stiffness
Central nervous system:
feedforward and feedback
Neutral zone:
region of laxity around the neutral resting position of a spinal segment
position of the segment in which minimal loading is occurring in the passive structure and active structures
Total vertebrae:
29 total
5 sacral
4 coccygeal and 3 joints and 2 facets
Alignment of upper cervical spine?
horizontal and 45 degrees in lower
Fryette’s First Law
when any part of the spine is in neutral position the side bending of the vertebrae will be to the opposite side as the rotation of the spine
Fryette’s Second Law
when any part of the spine is in a position of flexion or hyperextension the side bending of the vertebrae will be to the same side as the rotation of the spine
Fryette’s Third Law
If motion in one plane is introduced to the spine any motion occurring in another direction is thereby restricted
Can’t open restriction:
restriction of Flex/SB/Rot to the opposite side of pain
Can’t close restriction:
restriction of Ext/Sb/Rot to the same side of pain
Where does the majority of cervical rotation occur?
occipital atlanto region
Occipital atlanto flexion
15-20 degrees
Occipital atlanto side flexion
10 degrees
Atlanto-axial flexion/extension:
10 degrees
Atlanto-axial side flexion
5 degrees
Atlanto-axial rotation
50 degrees (primary motion)
4 parts of vertebral artery:
proximal
transverse
suboccipital
intracranial
4 parts of suboccipital portion of vertebral artery:
within transverse foramen of C2
between C2 and C1
in the transverse foramen of C1
between the posterior arch of atlas and its entry into the foramen magnum
5 D’s And 3 N’s
dysarthria Dysphagia Drop attacks Dizziness Double Vision Ataxia Nausea Numbness Nystagmus
Clinical prediction rule for patients with neck pain likely to benefit from TJM to Cspine:
symptom duration less than 38 days
positive expectation that manipulation will help
side to side difference in cervical rotation ROM of 10 degrees or greater
pain with posteroanterior spring testing of the middle cervical spine
Trauma patient order:
VBI and trauma hx C-spine rules and AROM screen Progress to eval if clear AROM, ROM, MRS functional movement screen special test
No hx of trauma order:
VBI screen AROM, PROM, MRS hypermobile vs. hypomobile functional movement screening special test treatment
C-spine:
Cognitively intact? Under 65? 45 d of rotation? injury circumstances? pain at rest in midline? paresthesia in arms?
