Lumbar muscle Energy - Exam 1 - Spring 2013 Flashcards
(35 cards)
What is the definition of Muscle Energy Technique?
- A system of diagnosis and treatment in which the patient voluntarily moves the body as specifically directed by the physican; this directed patient action is from a precisely controlled position, against a defined resistance by the physician.
When do you use muscle energy technique?
1) mobilize joints in which movement is restricted.
2) Stretch tight muscles and fascia
3) Improve local circulation
4) Alter related respiratory and circulatory function
5) Balance neuromuscular relationships to alter muscle tone.
What is the oculocervical reflex?
- patient makes eye movements, certain cervical and muscles reflexively contract and anatagonist muscles relax.
What is the respiratory assistance.
Physician directs the forces of respiration while simultaneously uses a fulcrum (hand) to direct the Somatic dysfuction through the barrier.
What is post-isometric relaxation?
Following increased tension on the Golgi tendon receptors (contraction), there is a refractory period in which there is a muscle relaxation (lengthening).
What is joint mobilization in muscle energy?
- Similar to HVLA but the patient actively contracts muscles to cause movement, use patient positioning and muscle contractions to restore motion.
What is reciprocal inhibition?
Contracting an agonist to relax the anatgonistic muscles.
What are absolute Contraindications of muscle energy?
- Fracture, dislocation or severe joint instability at treatment site.
- Uncooperative patient
What are relative contraindications?
- Moderate to severe muscle strains, advanced osteoporosis, severe illness (post-surg., patient on monitor in)
State the process of the muscle energy technique?
1) Engage the barrier
2) Patient contracts into the freedom of motion with a small amount of force for 3-5 sec. against physician resistance.
3) Wait 1-2 sec. (allowing tissue relax)
4) Physician re-engages the barrier
5) Repeat 3-5 times
6) Recheck
In the lumbar vertebral body what is the large size, what is the the higher portion?
- Large size designed to support weight, higher in the front, L4 at level of iliac crest.
What motion causes the facets to align backward and medial. And couples with ventral-dorsal translatory slide?
- Flexion/Extension motion
What motion couples with contralateral lateral translatory slide. The side bent- translates left.
- Sidebending
What intervertebral motion is couples with disk compression?
Rotation
Latissimus Dorsi:
Origin-
Insertion-
Action-
Innervation-Origin: T7-T12, Iliac crest, Thoracolumbar fascia
Insertion: humerus
Action: Adducts, extends, internally rotates arm, Extension and sidebending of lumbar spine
Innervation- Theracodorsal nerve (C6-C8)
Where can the pain be located in hypertonicity of the latissimus dorsi?
- Yields shoulder pain.
What is the gluteus maximus:
Origin?
Insertion?
Action?
Innervation?Origin: Thoracolumbar fascia, Dorsal sacrum, Sacrotuberous ligament, ilium,
Insertion: Iliotibial band, Greater tuberosity of femur
Action: Extend hip and stabilizes torso
Innervation: Inferior gluteal nerve (L5, S1-S2)
What is the Erector Spinae:
Origin?
Insertion?
Action?
Origin: Sacrum
Insertion: cervical
Muscles included are iliocostalis, longissimus, spinalis
- Action: Bilateral contraction- extension;
Unilateral contraction- extension and ipsilateral sidebending
What is the Quadratus Lumborum:
- Origin? - Insertion? - Action? - Innervation?
Origin: 12th rib, lumbar transverse processes
Insertion: iliolumbar ligament, iliac crest
Action: bilateral contraction creates extension, unilateral contraction causes extension with ipsilateral sidebending
Innervation: T12 and L1-L4 ventral rami
What is the action of the multifidus and rotators?
Postural muscles.
Action: control and stabilizes individual vertebral motions
Psoas Major- Origin Insertion Action Insertion
Psoas Major
- Origin: Transverse process of T12-L5
- Insertion: Lesser trochanter of femur
- Action: Flexes and internally rotates hip
- Innervation: L1-L3 (2-4) ventral rami
Illiacus-
Origin:
Action:
Iliacus
Origin: superior 2/3 of iliac fossa inner lip of illiac crest, ventral sacroilliac and iliolumbar ligaments, upper lateral sacrum.
Insertion: Lateral Tendron of psoas
Actions: Hip flexion, lumbar sidebending (unilateral contraction), constant activity in erect posture, important in function and stability.
What is the course of the anterio longitudinal ligament?
What is the course of the posterior longitudinal ligament?
-What two pathologies can be caused by narrowing of posterior longitudinal ligament?
- From base of occiput to the anterior sacrum
- From the posterior body of the axis to the sacrum
- decreases support and increases risk of disc herniation
What is the attachment of the iliolumbar ligament? What is its action?
Attachment: transverse processes of L4 and L5 and iliac crest.
- Increases stability at the lumbosacral junction (commonly strained in traumatic injuries)
