2- QL, Psoas, Piriformis Flashcards
origin/insertion, function, and dysfunction of the quadratus lumborum
iliac crest and iliolumbar ligament–> 12th rib, iliac crest, and transverse process L1-4
assist respirtation, bilateral extension, unilateral sidebending
hip and groin pain, exhalation 12th rib dysfunction
origin/insertion, function, and dysfunction of the psoas
Psoas origin L1-4 (L5)–> lesser trochanter on the medial side of the femur
flexes trunk and lumbar, laterally flex lumbar unilaterally and shortens/externally rotates the leg
ipsilateral L1 L2 dysfunction and special cases
Left psoas spams engages the ____ oblique axis, in neutral creates_____ and in non-neutral creates______
Left, right pole moves forward, left on left; right pole moves backwards, right on left
Left psoas, left oblique axis, non-neutral, sacrum rotates_____, right pole moves_____, deep sulcus on the ______, ILA on the _____, meaning it is a _____ dysfunction, NNR_S_
Right, backwards, Left, Right, Right on Left
pelvic shift occurs to the _____ causing ____ spasm and pain that radiates_____
opposite side, piriformis, no further then the knee
Somone with a leg that is externally rotate and shorter is indicative of _____ syndrome and can be caused by a tight _____
piriformis, psoas
QL is treated by
pulling on ASIS as they push it towards the table
what can cause a tight psoas
bending for a long time then returning to neutral
when a person is bent over the ____ fibers tightens, then when the pt returns to neutral the body thinks the psoas is over stretched before the ____ fibers have reached their usual resting length
Intrafusal, extrafusal
What test do you use to diagnose a tight psoas
Thomas Test
ME for psoas
Prone and resit them pushing leg into table
treatment of chronic shortening of psoas
push affected knee into table and opposite leg to chest
how to treat a weak psoas, what does it cause in the lumbar
increases lordosis and protruding abdomen, have them push their pelvis into the table
origin/insertion, function, and dysfunction of the piriformis
Anterolateral border of the sacrum at the sacroiliac joint capsule; Anterior portion of the sacrotuberous ligament–> Superomedial aspect of the greater trochanter of the femur
- External rotator
piriformis syndrome, hip pocket neuritis
Piriformis syndrome can cause perineural inflammation due to
the release of vasoactive substances from an inflamed piriformis
In what % do pt’s have a piriformis with 2 tendinous origins or separate components of the sciatic nerve with it passing through the piriformis
10%
origin/insertion, function, and dysfunction of the hamstring
Ischial Tuberosity Lateral condyle tibia, lateral aspect of fibula
Hip Extension
Knee Flexion
Tight= posterior innominate dysfunction
how to treat a tight hamstring
leg on should and have them push down
origin/insertion, function, and dysfunction of the quadriceps
Rectus femoris/ASIS tibial tuberosity via patellar ligament
Extends leg at knee
Rectus femoris cross so hip flexor as well
Positive Thomas Test
innervation of the QL
T12-L3
what goes over the pubuc ramus and under the inguinal ligament
psoas
a tight psoas does what to the lumbar curvature
flattens it
If a chronic psoas is left untreated the pt can get
fibrosis of muscle
what is the key between a psoas syndrome and disc problem
the stature of the pt, bent over and side bent
Low back pain is not common in ____
piriformis syndrome
