Posture Flashcards
What are two benefits of optimal posture?
- Reduced E cost
2. Reduced stress on anatomical structures
When the LOG runs through joint axis, this = _________.
equilibrium
When the LOG does not run through a joint axis, _____ is created.
torque
When torque is created around a joint axis, _____ is required to counteract this torque. This can be generated by _____ or ______ tissues.
Force; active; passive
LOG falls _______ to lateral malleolus.
anterior
Because of where the LOG falls relative to the lat malleolus, a ________ moment is created, and _______ create stability.
dorsiflexion; plantar flexors
The LOG falls ______ to the knee joint axis.
anterior
Because of where the LOG falls relative to the knee joint, an _______ moment is created.
extension
The maintenance of the knee in an extended position is stabilized by what 4 structures?
- ACL
- Posterior capsule
- Gastrocs and hamstrings
- Soleus
Where does the LOG usually fall relative to the hip joint axis? What type of moment is created?
posterior; extension
What 3 structures is the hip stabilized by?
- Iliofemoral ligament
- Iliopsoas
- Hip extensors
The LOG goes through the vertebral bodies of the __ - spine and ___ - spine.
C;L
LOG falls _______ to the T spine vertebral bodies, creating a ______ moment./
anterior; flexion
What is the T spine position stabilized by?
posterior ligaments
The moment at the spine is greatest at the apex of each curve, = C__/__, T__, L___.
4/5; 6; 3
LOG falls ______ to the head axis, causing a _______ moment.
anterior; flexion
What is the head position stabilized by?
- ligamentum nuchae
- tectorial membrane
- posterior cervical muscles
In what 3 ways do we maintain our body alignment?
- Static stabilizers
- Dynamic stabilizers
- Neural control
Postural muscled have a great ratio of Type ___ fibres.
1
In spinal stability, the NS activates trunk muscles in ________ of the load imposed by limb movement.
anticipation
A postural _______ = posture that deviates from normal alignment but does not create structural limitations.
fault
What 2 things does a postural default result in?
- Increased EE
2. Abnormal stresses on supporting structures
Postural ____ _______ = pain that occurs from mechanical stress when a person maintains a faulty posture for a prolonged period.
pain syndrome
Postural ________ = adaptive shortening of soft tissues and muscle weakness that developed due to prolonged poor postural habits, position assumed following trauma or surgery, and structural factors.
dysfunction
