OMM Review Flashcards
Def isotonic contraction
the muscle tension remains the same throughout the contraction
2 types: concentric and eccentric
Concentric muscle contraction
the muscle gets shorter without an increase in tension
type of isotonic contraction
Ex: biceps curl
Eccentric muscle contraction
the muscle gets longer without an increase in tension
type of isotonic contraction
Ex: end of curl bringing the weight back down
Def isolytic contraction
Outside force completely breaks the patient’s force, leading to a forced elongation of the muscle
Ex: arm wrestling
Def Isometric contraction
Contraction force from the patient matches that of the physician, leading to no change in the muscle’s length
Ex: OMM TREATMENT
Law of stacking
as one vertebral segment goes into one plane of motion, the range of motion in the rest of the planes will decrease
Ex: the more one flexes, the less one will be able to rotate and SB
Thoracic Spine Rule of 3’s
T1-3 = directly posterior T4-6 = down 1/2 T7-9 = down 1 T10 = down 1 T11 = down 1/2 T12 = directly posterior

Tender point def
hypertonic portion of muscle that’s tender, but with pain that doesn’t radiate
happens by a too-rapid stretch
Psoas origin and insertion
Origin = T12-L5 Insertion = Lesser trochanter
Psoas action
flexion and ER
Psoas CS
2/3 of the way between ASIS and Umbilicus
Flexed Sidebent Towards, ER
Sternocleidomastoid origin and insertion
Origin = sternal head on the manubrium and clavicular head on the medial third of the clavicle Insertion = mastoid process
Sternocleidomastoid action
Flexion, sidebending toward, and rotating away
Sternocleidomastoid CS
AC7
FSTRA
Midline axis of Sacrum
postural motion
spinal flexion causes sacral extension around this axis
R and L Oblique axis of Sacrum
Go through their eponymous sacral sulci and the ILA of the contralateral side
Weight shifting during gait happens along these axes
Superior axis of Sacrum
Runs through the sacrum superiod to the middle axis
where respiration and cranial motion occur
inhalation leads to sacral extension around this axis
Inferior axis of Sacrum
axis around which the innominates rotate
L5 and Sacrum
L5 rotation occurs in opposite direction from sacrum
L5 sidebending results in same-sided axis for sacrum
L5 F/E occur in opposite direction from sacrum
Ex: L5 FSrRr, sacrum - left on right
typical ribs
3-10
has all 5 landmarks: head, neck, tubercle, angle, and shaft
atypical ribs
1 - no angle
2 - extra tubercle
11 and 12 - no neck or tubercle
true ribs
1-7
connects directly to the sternum
false ribs
8-10
indirectly attach to the sternum
floating ribs
11-12
do not connect to the sternum at all
pump handle ribs
1-5
anterior portion of the rib moves superior during inhalation
posterior portion remains stable
bucket handle ribs
6-10
anterior and posterior portion remain stead, but medial portion swings up and down
caliper ribs
11-12
the posterior portion of the rib remains still, while the rest of the rib moves laterally
Primary muscle of respiration
diaphragm and intercostals
Secondary muscles of respiration
scalenes, pectoralis minor, serratus anterior, and latissimus dorsi
Exhalation rib 1
anterior and middle scalenes
Hand on head
Exhalation rib 2
posterior scalenes
Hand on head
Exhalation ribs 3-5
pectoralis minor
arm fully flexed
