5: POSTURE Flashcards
What is optimal posture
The ability of the body to hold itself in neutral alignment against the force of gravity with minimal muscle activity
What is the natural curve of the spine
s shape
How many natural curves are in the spine
4
What are the 9 main causes for postural deviation
- Fashion
- Work/school
- Emotional state
- Sport
- Hereditary conditions
- Injuries
- Pregnancy
- Disability
- Obesity
What is Hyper-Kyphosis
Exaggerated kyphotic (hump) curve of the thoracic verterbrae (head and shoulder forward of plump line)
What happens to the muscles in hyper-kyphosis
Excessively shortened and lengthened muscles in the front and back of the upper body.
Pecs - shortened
Traps - lower and mid are lengthened, upper shortened
Rhomboids - lengthened
What causes hyper-kyphosis
- Genetics
- Lifestyle factors that lead to bad posture
- Deformity of spine formation
What is Hyper-Lordosis
Excessive curvature of the lower spine - inward curve of the lumbar spine. Anterior pelvic tilt, making bum look bigger. Abdominal forward of the plumb line and buttocks behind
What causes hyper lordosis
Poor sitting posture
Development from problems during child birth and pregnancy
What happens to the muscles in hyper lordosis
- Erector spinae - shortened
- Glutes - lengthened
- Hip flexors - shortened
- Transverse abdominis - weakened
- Rectus abdominis - lengthened
What is scoliosis
a sideways curvature of the spine. ‘s’ shape when observed from the back rather than side
What is the plumb line
The plumb line is an imaginary line that runs from the top of the head through the center of the body and down to the feet. It is used as a reference line to assess posture and alignment.
What is the ideal alignment in the plumb line in posture?
In the ideal alignment, the plumb line should pass through the center of the ear, the shoulder, the hip joint, the knee joint, and the ankle joint.
What are the benefits of maintaining proper alignment in the plumb line posture?
Maintaining proper alignment in the plumb line posture can help reduce stress on the joints, prevent injuries, improve breathing and circulation, and enhance overall movement efficiency.
What does Hyper-Kyphosis affects
- Shoulder join stability; resulting in tension in the neck and muscles = headaches
- Breathing less efficient
What does Hyper-Lordosis affect
Places pressure on intervertebral discs, compressing and synovial facet joints between each vertebra may become overloaded = lower back pain
