Cervical Biomechanics Flashcards
Motion is determined by the ______ of the bone and the characteristics of the ______.
shape;discs
Motion is guided by _______.
Facet Joints
OA biomechanics are SB and Rotated__________ and show Type _______ mechanics.
coupled to opposite sides. Type 1 LIKE
How much can the OA rotate?
30-40 degrees
Dysfunctions of the OA are typically _________ and are rarely _________
Flexed or Extended; rarely neutral
Ex: OA E RrSl
The 4 rotates of the neck are ?
RCP(min) RCP(maj) ObCapInf, ObCapSup.
The Longus capitis muscles is connected to the________.
Anterior scalene muscle
C1-C2 or Atlanto -Axial Biomechanic’s primary motion is _______?
Rotation
Ex: C1 Rr or Rl
The SCM has SB and Rot ________
opposite
If a Pt is SBr Rotl Then the _______ SCM is affected
Right
Scalenes have SB and R __________biomechanics
Toward; same side
If a pt is SBr Rr then the _________ scalene is affected.
Right scalene
The Anterior Scalene muscles are continuous fibers that are connected to the __________.
Longus Capitis Muscle
C2-C6 Biomechanics are _______ and follow Type _____ mechanics
Same side : Type II LIKE
- C7 behaves like a thoracic segment( typical fryette)
The most common C2-C6 dysfunctions are __________ and ________ are rare.
Flexion and Extension: Neutral
The ROM for C4-C5_____
The ROM for C5-C6______
Therefore the greatest ROM segments in the neck are______?
20
20
C4-C5
The treatment sequencing is 1. 2. 3. 4.
- OA or CO ( top)
- C7 and T1 ( bottom)
- C2-C6 (middle)
- Atl-Axial ( anything left) ( C1)
Pain referred for C2 C3 C4 C5
C2- side of the head and top half of ear
C3- Bottom half of the ear, jaw,(neck) and top of shoulder
C4- bottom traps, clavicle area to deltoid/chest
C5- Deltoid
What are in this pain referral do we need to pay attention to? Why is this very important?
C3-C5
Because this is the innervation for the diaphragm. Could possibly be an MI
A vertebral disc will handle a _________ stress load worse but can handle _________ stresses much better.
vertical (90) and horizontal (0-15)
Normal discs will bulge ______ the direction of motion and flatten on __________.
Degenerating discs will bulge _______ from the direction of motion and flatten on __________.
toward and flatten on opposite sides
away and flatten on the same sides
What are Schmorl’s nodes?
They are disc material that protrude into the surface of the vertebral body and sometomes contacts marrow and leads to inflammation.
