Iliopsoas MMT

A

Patient supine, if testing left left put left leg into flexion/external rotation/abduction and stabilize right side pelvis with other hand, push in extension and slight abduction direction

Patient seated, passively put into full flexion and apply downward force

Q

Meniscoid intra articular structure purpose

A

Meniscoid provided lubrication to cartilage and moves with the facet. Can cause pain coming up from flexion as it is not re-entering properly

Q

What happens to each with age
- disc and body
- what causes narrowing
- proteoglycans
- nucleus

A

Disc increases in size and body decreases in height

Nucleus degradation

Less proteoglycans leading to less water which increases rigidity

Increased pressure on annulus as nucleus is less able to exert fluid pressure

Q

QL
- attachment
- action

A

12th rib to iliac crest

Fixates rib during inspiration
Controls buckling
Side bending lumbar spine

17
Q

TFL
- attachment
- action

A

Femur flexion, abduction, internal rotation

18
Q

Intertransversarii Lateralis

A

Proprioceptive transducers

19
Q

Multifidus (deep and superficial fibers)

A

Deep: run 2 levels, help prevent meniscoid displacement

Superficial: run 3-5 levels, extension due to longer lever arm and mainly counteracts abdominal flexion with rotation

20
Q

Erector spinae

A
  • longissimus thoracis: unilateral SB and B/L ext
  • iliocoatalis lumborum: unilateral SB and B/L ext/rot
21
Q

Thoracolumbar fascia

A

Lateral raphe of 3 layers

Prevents dorsal displacement of back muscles and stability for low back

22
Q

LAROM values

A

Flx: 40-50
Ext: 15-20
Rot: 5-10
SB: 20

23
Q

IV foramen opens how much with flx and closes how much with ext

A

Opens 19%
Close 11%

24
Q

SB and rotation couple how in lumbar spine?

A

Opposite

25
Q

Right rotation in lumbar spine arthros

A

R rot= R goes down and back and opens, L goes up and forward but closes

26
Q
