Psoas syndrome involves what reflex loop?
Pathophysiology? |
Gamma reflex
muscle in position of strain --> rapidly lengthens, CNS thinks overstretched, reflex contraction, microtrauma, spasm impulses ascend via opposite STT |
|
|
What happens to impulses in the spinal cord, brain?
CNS changes? What happens in the peripheral tissues? |
A-d fibers sends impulses to neothalamus, somatosensory tract, C-fibers to key locations - behavior mods, conditioned behavior, avoidance
sympathetic stimulation, vasoconstriction - lowers pain threshold, NE amplifies pain response inflammatory peptides get released - lowered threshold |
|
|
What is a facilitated segment?
Origin/Insertion of psoas major? Action of piriformis? What nerve/vessels are just superior to the piriformis? |
low-threshold spinal reflex - dysfunctions
T12-L5 to lesser trochanter (straight lower extremity) - hip ext. rotation (bent 90 deg.) - hip abduction Superior gluteal nerve, vessels |
|
|
Pudendal nerve/vessels, inferior gluteal nerve/vessels are located where?
Pt. with low back pain radiating down the thigh, hip/butt pain, tederness over piriformis, NO NEURO deficit What are some functional pathologies that can cause it? |
Inferior to the piriformis
Piriformis syndrome Foot planted, trunk rotated, awkward sitting position, sacral base unleveling, pelvic instability |
|
|
How should you examine a patient to check for piriformis syndrome?
How to treat with OMT? What should the patient do? Drugs to treat? |
transverse plane motion of the hip, check counterstrain points (piriformis is in belly of muscle), trigger points
Strain/Counterstrain, MFR, ME, spray and stretch, inject tender points w/ saline, Bupivacaine stretches, warm baths, etc analgesics, NSAIDs, injection, surgical transection of piriformis |
|
|
Symptoms of Psoas syndrome?
Causes? Postural changes with chronic psoas syndrome? |
can't sit/stand upright, T-L, L-S, SI, gluteal pain; forward bent, one leg short/externally rotated
sit ups, flexion stress (over table), chilling, trauma, flat lumbar lordosis, metastatic cancer, postural changes, bursitis excess cervical/lumbar lordosis, thight leg muscles |
|
|
Which stage has +Thomas test, flat lordosis, pain at belt line?
Key dysfunction in Stage 2 (unilateral dominant)? What is added in Stage 3? Stage 4? Stage 5? |
Stage 1 (bilat spasm)
L1 F RrSr 3 - sacral torsion 4 - piriformis spasm 5 - sciatica |
|
|
Drugs to treat Psoas syndrome?
Psoas syndrome patients should not do what? If a pt presents in high stage psoas syndrome, which OMT should you not use? |
NSAIDs, muscle relaxants
sleep on stomach, use heat pads, slouch when sitting, bend forward, do sit-ups, lean back when standing HVLA - use counterstrain, ME, MFR |
