What do we think is the cause of cervical spine somatic dysfunction
Compensatory after for dysfunction of lower parts of spine
Rotational testing in the. Cervical spine. Requires us to contact lateral mass (lateral to spinous process) and rotate them in what plane
Transverse plane
If you induce a force in the transverse plane on the left lateral mass what motion are we inducing in cervical vertebra
Rotate right
Translation of cervical vertebra (lateral segment movement: left to right or right to left) induces motion in which plane
Coronal plane
If we move a cervical vertebra in the coronal plane: translation from left to right what do we document this motion as
Sidebent left
If there is more restricted motion in the cervical vertebra while the neck is flexed how would we name it
Extension dysfunction
Which part of the chart should include documentation of somatic dysfunction
Objective portion (of SOAP note)

What are the major motions of OA joint
Flexion and extension (Sagittal plane motion)
What type of mechanics are displayed at the OA joint

To assess restriction of motion at the OA joint contact posterior occipital with middle finger and lateral aspect with index finger. Assess rotation right by lifting anterior on which side?
Left
To assess restriction of motion at the OA joint contact posterior occipital with middle finger and lateral aspect with index finger. Assess side bending left by inducting what motion?
Translation

Main motion of thoracic spine
Rotation (because of ribs we can’t do much else)
Where in the spine can we do the most rotation? Second most?
Most- AA joint
Second most- thoracic vertebra
Why can we flex more than extend in thoracic spine
Because of the natural kyphotic curve
Where do we find sympathetic ganglion
Paravertebral ganglia of sympathetic trunks
Visceral distrubance often causes increased musculoskeletal tension in somatic structures innervated from the same spinal level. How can we reduce somatic afferent input thus reducing somatosympathetic activity to the organ
OMT treatment! treat at the transverse process that is tense

T3 for spine
T7 for inferior angle

T10-11
Which spinal segments correspond to sympathetics that supply the remainder of lower abdomen (distal 1/3 transverse colon, descending colon, sigmoid colon, rectum)
T12-L2
Which rib articulates posteriorly with cephalon border of scapula
Rib 1

8-10
Which ribs are floating (no eternal attachment
11-12
Which ribs are “typical” (with head neck tubercle and body)
3-9
What makes rib 1 atypical?
Single facet on head since it articulates with only T1, groove for subclavian artery and vein, scalene tubercle for anterior scalene attachment
What makes rib 2 atypical?
Tuberosity for serratus anterior
What makes rib 10-12 atypical?
Single facet on head because they articulate with ONLY ONE vertebra

What is the motion of ribs that is analogous to flexion / extension (rib 1-6 moves anteriorly)

What is the motion of ribs that is analogous to abduction/ adduction (rib 1 and 7-10 moves laterally)
Bucket handle motion
What is the motion of ribs that is analogous to internal/ external rotation (rib 11-12 pivoting because they have no anterior attachment)
