cervical Flashcards
C2-C7 are capable of performing Non-Neutral mechanics. T/F
True
Application of a passive stretch force to the Right Splenius Capitus muscle, would require which motions?
CO Flexion
CO lateral Flexion to the left
Describe Force Coupling of Rhomboids, Lev scap, and pec minor muscles.
force coupling between the Rhomboids, Lev scap and pec minor would result in scapular downward rotation.
Rhomboids- retracts scap medial on a superior angle
lev scap - pulls the medial superior angle superior
pec min - depresses the more lateral side of the scap
Describe the mechanics of a positive screening test outcome caused by the middle scalene muscle being tight.
Middle scalene. positive travell’s test.
the tight middle scalene pushes the neuro vascular bundle against the ant. scalene and causes the pulse to drop out or weaken and a possible recreation of symptoms. if negative, take a deep breath in to contract mid scalene making it push even more firmly against the neuro vascular bundle.
Eccentric contractions of the RCP major and RCP Minor would control which motion?
Flexion of CO
Which of the following describes the control for Left Rotation of C1?
-EC of the Right OCI and RCP Major
-EC of the Left OCS and RCP Minor
-EC of the Right OCS and RCP Minor
-EC of the Left OCI and RCP Major
EC of the Right OCI and RCP Major
Describe the mechanics of how a slump test may present positive based on a picture of the lumbar disc pushing posterior lateral.
The lumbar flexes while the sacrum extends to create posterior lateral pressure on the nerve root. The intervertebral disks get pushed posterior lateral adding pressure to the nerve root resulting in increased or recreated symptoms and a positive outcome
C2-C7 are capable of performing Neutral Mechanics.
true or false
False
Describe Force Coupling of trap and serrratus ant. muscles.
upper trap CC to pulls the acromion superior
Mid CC to pull the lateral spine of the scap superior/medial
Lower trap CC to pull medial spine of the scap inferior
the lower fibers of the serratus Ant. CC to pull the inferior side of the scap lateral
All this motion creates uppward rotation of the scapula
C2-C7 are rotating to the left. describe the osteokinematics?
SPs move to the right
Rt TPs move anterior
Lt TPs move posterior
Adson’s test is positive on the right. Describe the mechanics of this outcome?
The right anterior scalene is being stretched with right cervical rotation
Which plane best describes the orientation of the facet joints between C2 and C3
Horizontal Plane Orientated
Which muscle may create the force used to flex CO?
Longus Capitis
During cervical distraction test, which force is being applied to the facet joint capsules?
Tensile
The levator scapula is concentrically contracting. Which motions may be occurring?
Scap Downward Rotation and cervical lateral flexion
Which of the following occurs during non-neutral mechanics in the vertebral column?
rotation occurs to the same side as sidebending
Which segments performs the majority of cervical rotation?
C1 moving on C2
Flexion and Extension of C0 occur on which plane and axis?
Sagital/ X
What is the MAJORITY of force creating flexion of the lower cervicals from anatomical position?
Gravity
For VBI test to be effective, why must the lower cervical segments be fully extended?
To prevent rotation in the lower cervical
Describe the mechanics of a screening test used to assess for inflammation of the supraspin tendon.
Supraspinatus tendon - Drop arm testing
Pressure on the abducted humerus, causes deltoid to contract pulling the head of the humerus superior in the glenoid fossa, putting pressure against the acromion process pressing on the sub acromial burssa and the suprasinatis tendon.
Describe the mechanics of the screening test used to assess for impingement of the costcoclavucular nerovascular bundle of nervous tissue.
Military brace, costal clavicular impingment of the neuro vascular bundle.
Trying to irritate the neuro vascular bundle by compressing it between the clavicle and the ribs by hyper extending the GH, causing anterior tilt of the scapula and pushes the clavicle down onto the first rib. deep breath in brings the rib closer to the clavicle furthering the pressure or making the space even more narrow.
Therapist is pushing on the right articular pillar of C3. describe the mechanics occurring?
The right facet is closing and the left facet is opening
C4 is performing Left sidebending. Describes the arthrokinematics?
The left facet is closing the right facet is opening
Describe the kinesiology occurring if the OCI muscle is concentrically contracting.
OCI. the atlas rotates to the left on a horizontal plane, around the y axis, the right inferior facet of C1 opens, the left inferior facet of C1 closes, the posterior dens of C2 articulates with the anterior facet of C1. The force is the left OCI the control is the right OCI, Right RCP Maj.
The right upper trapezius can eccentrically control which motions?
right rotation
left sidebending
flexion
Describe the force creating initial cervical flexion in an acceleration/ deceleration injury of the cervical spine?
Force is applied to the body from anterior to posterior (ie-running into the car in front of you)
If the lower cervical spine presents with an excessive lordotic curve, which motion would concentric contraction of both SCM muscles create?
Extension
Rotation of C1 occurs on which plane/ axis?
Horizontal/ Y
List the motions controlled via eccentric contraction of the pec minor muscle.
Pec minor, scap upward rotation, scap elevation, exhalation
What occurs at the facet joints in the cervical spine during cervical compression test?
Approximation
Understanding the biomechanics of an injury assists the Therapist in?
indicates which tissues may have been strained
indicates the potential severity of the injury
indicates the potential pattern of secondary muscle guarding
