Topic 3 - Posture Flashcards
A debated subject among health professionals that holds strong cultural, political and societal meanings, but these beliefs are often unsupported by evidence.
Posture
“____” posture is generally overemphasized and is referred to as being “straight” and “aligned.” “___” posture is associated with slouching.
“Good”
“Bad”
Physiologically, all postures or movements load _______ differently, so context becomes an important consideration.
Tissues
The total force through particular musculoskeletal tissue.
Tissue Loading
The configuration of the body’s head, trunk and limbs in space. It includes position and relative relationships of the bony skeleton and supporting soft tissues.
Posture
Posture is in part the relative ___________ of the parts of the body to each other, however what needs to be considered is the particular _______ in which it is used.
Arrangement
Context
Posture is a shifting pattern of righting and ___________ reflexes, habits and adaptive responses to things such as _______, ADL’s, psychological states and personal anatomical limitations.
Stabilizing
Gravity
Functional and _____________ considerations are integral to the concept of posture as are the consequences of various postures to performance and _______.
Biomechanical
Comfort
identifying and describing the relationships between various factors which influence posture is integral to the analysis needed to identify ___________, treat them with the appropriate massage techniques and provide the _________ necessary to help with postural complaints.
Impairments
Self-Care
T/F - Many MSK complaints are attributed to the narrative of muscle imbalances, which research can back up with evidence.
False - Many MSK complaints are attributed to the narrative of muscle imbalances, BUT research CANNOT back THIS up with evidence.
There is evidence that posture can shape ____ and that there are emotional dimensions of posture including links to __________.
Mood
Depression
T/F - Individuals suffering from depression often show greater anterior head inclination, thoracic kyphosis and a slumped posture.
True
Some ____ ____ posture suggestions include:
- Frequent movement
- Avoid prolonged sitting
- Minimal use of muscular effort/problematic loading for sustained periods
- Efficient use of muscles to avoid fatigue
- Efficient movement at a joint
Pain Free
________ ( ________ ) curves are normally present in the lumbar and cervical regions.
Lordotic (Anterior)
________ ( _________ ) curves are normally present in the thoracic and sacral regions.
Kyphotic (Posterior)
Normal curvature and flexibility of the spine allow for distribution of ______ and efficient use of the associated muscles and joints.
Forces
The weight bearing and shock absorbing portion of the spine.
Anterior Pillars (aka. Vertebral Bodies) & Intervertebral Discs
Made up of the articular processes and facets. They provide the gliding mechanism for movement.
Posterior Pillars (aka. Vertebral Arches)
The posterior pillars also include bony ______ (e.g. TVPs & SPs) to which the muscles attach and function to allow for ________ and control. They also provide spinal stability.
Levers
Movement
When it comes to ________ postural alignment, the list of landmarks that should align from a _______ view are:
- Anterior ankle
- Head of fibula
- Greater trochanter
- Bodies of lumbar spine
- Middle of acromion
- Cervical spine
- External auditory meatus
Standing
Lateral
T/F - For athletes, imbalances between agonist and antagonist muscles is something we want to correct.
False - For athletes, imbalances between agonist and antagonist muscles is something we DON’T ALWAYS want to correct.
The pelvic tilt from ASIS to PSIS should be ____ or PSIS is slightly ______. The average is 0-15 degrees.
Even
Higher
ASIS and the pubic bone should be aligned __________.
Vertically
A line through pubic symphysis and PSIS in the transverse plane.
Pelvic Angle
How many degrees is the pelvic angle?
30 degrees
The following are part of ________ posture:
- Medial border on rib cage
- 3-4 patient’s finger widths from midline
- Stretch weakness of scapular retractors
- Inferior angle sits on thorax
- Spine of scapula at T3
- Spine of scapula at 15 degrees of inclination
Scapular
_______ stresses the structures that help to maintain upright posture.
Gravity
The point in the center of an object, where the objects mass behaves as if it were concentrated. It will change in different postures.
Center of Gravity
In anatomical position, the center of gravity of the upright adult human is anterior to the ___.
S2
The basic level of tension required to brace our joints and maintain cellular activity. It is unlike resting tone because constant muscle activation is needed.
Postural Tone
What are the 3 subsystems that need to be considered for postural stability?
1) Passive (e.g. inert structures/bones & ligaments)
2) Active (e.g. muscles)
3) Neural Control (e.g. PNS/CNS)
T/F - Self-care should incorporate all 3 subsystems of postural stability.
True
___________ and muscular _________ are often a combination of inert tissue damage, insufficient muscular strength or endurance and poor neuromuscular control.
Instability
Imbalance
The inability to maintain equilibrium under dynamic and static conditions, such as preparation of movements, perturbations (e.g. uneven surfaces) and quiet stance (e.g. standing still).
Postural Instability
For weight bearing joints to remain stable, there must be a force to __________ the force that is created by greavity.
Counteract
____________ to gravity is provided by:
- Muscular activity and inert tissue
- Bones, muscles and joints from body levers
- Resistance further from axis leads to increased use of muscles
- Neural control coordinates response of muscle
Counterforce
When the gravitational force is posterior, the hip _______ are involved and passive support by the iliofemoral ligament. When gravitational force is anterior, the hip _________ assume more responsibility to maintain posture.
Flexors
Extensors
Center of gravity falls ________ to the atlanto-occipital joints. The cervical ________ muscles counteract this force into flexion.
Anterior
Extensor
T/F - When postural deviations are extreme, there is more dependence on active structures to maintain stability.
False - When postural deviations are extreme, there is more dependence on INERT structures to maintain stability.
T/F - Muscular endurance is promoted more than strength to maintain posture.
True
T/F - Many MSK complaints can be attributed to the stresses from prolonged postures and movement patterns.
True
