Movement Science Unit 7 Posture Flashcards
Why is Spine Stabilization important?
- The spine is vulnerable
- To protect articular surfaces
- Prevent injury or reinjury
- To facilitate healing
- To decrease pain
- To improve performance
Which muscles are crucial in providing lumbar spine stabilization?
Which muscles are affected as a result of LBP?
- Lumbar Multifidus
- Transverse Abdominis
- Internal and External Obliques
What muscles are part of the Intrinsic Stabilization subsystems?
- Multifidus
- Transverse Abdominus
- Diaphragm
- Muscles of pelvic floor
Also:
- Internal Oblique
- Transversospinalis (Semispinalis, multifidus, and rotatores)
What are signs of dysfunction with the intrinsic stabilization subsystem?
- Abdominal Distension (abdomen expands)
- Change in LPHC alignment
–Excessive lordosis (APT)
–Excessive Forward Lean
–Asymmetrical Weight Shift
What Muscles are part of the Anterior Oblique Subsystem?
- Adductors
- External Oblique
What are the signs of dysfunction with the Anterior Oblique subsystem?
- Change in LPHC or femoral alignment
–Excessive Lordosis (APT)
–Excessive Forward Lean
–Genu Valgum
–Asymmetrical weight shift
What muscles are part of the Posterior Oblique Subsystem?
- Glute Max
- Latissimus Dorsi
What are the signs of dysfunction with the Posterior Oblique subsystem?
- Change in LPHC or Femoral Alignment
–Excessive Forward Lean
–Excessive Lordosis (APT)
–Genu Valgum
–Genu Varum
–Asymmetrical Weight Shift
What muscles are part of the Lateral Subsystem?
- QL
- Glute Med
- TFL
- Adductors
What are the signs of dysfunction with the Lateral Subsystem?
- Frontal Plane Changes in Pelvis or Hip Alignment
–Genu Valgum
–Genu Varum
–Asymmetrical Weight Shift
What muscles are part of the Deep Longitudinal Subsystem?
- Bicep Femoris
- Tibialis Anterior
- Peroneus Longus
Also:
- Sacrotuberous Ligament
What is the difference between Global and Local muscles?
Global muscles only provide indirect stability to the spine
Local muscles provide segmental stability and must be addressed first
What are the characteristics of the Lumbar Multifidus?
70% of stabilization comes from this muscle
The lumbar multifidus is the deepest posterior spinal muscle
- Unilaterally it would do trunk flexion, side bending and rotation of the opposite side
- Bilaterally it would extend the trunk and stabilize the vertebral column
More of a tonic muscle
How is the lumbar multifidus affected by LBP?
If you’ve had a hx of LBP, first time unilateral P!, these pt. had atrophy of the multifidus on the same side and the same segment as their acute unilateral LBP
What are the characteristics of the Transverse Abdominus?
This is the deepest abdominal muscle
- This muscle is in charge of compression, support and protection for the abdomen
- This muscle is recruited prior to any other muscle when there is expected and unexpected loading of the spine
