Pediatric Cardiopulm conditions Flashcards
What postural/ trunk control consequences does weak abdominal obliques have?
- Passive Lumbar Lordosis
- Protruding Tummy
- Lower Rib Flaring
- Decreased Trunk Rotation
- Unable to Weight Shift
- Dependence on Rectus Abdominals
What postural/ trunk control consequences does tight pec minors have?
- Forward Shoulders
- Scapular pulled laterally and anteriorly, away from thoracic wall
- Upper Thoracic Flexion
What postural/ trunk control consequences does weak serrates anterior have?
Weak upper fibers– medial edge of scapula leaves thoracic wall
What postural/ trunk control consequences does decreased active upper thoracic extension have?
- Kyphotic upper trunk
2. Passive overlengthening of scapular retractors (ineffective length-tension relationship as a result)
What postural/ trunk control consequences does decreased rib stability have?
Serratus anterior will elevate the ribs rather than stabilize the scapular against the thoracic wall
What respiratory consequences does weak abdominal obliques have?
- Ineffective cough
- High Chest
- Retained horizontal rib alignment
- Tight rectus leading to pectus excavatum
- Child may use diaphragm for trunk control, limiting its function as a primary mm of respiration
What respiratory consequences does tight pec minor have?
Anterior upper chest cannot adequately expand
What respiratory consequences does weak serratus anterior have?
- Decreased structural reinforcement of the posterior chest wall
- Interdigitation of the lower fibers of serratus anterior with the external abdominal oblique will interact to affect the dynamic stability of the ri
What respiratory consequences does decreased active upper thoracic extension have?
Approximation of the upper ribs decreased upper chest mobility decreased oxygenation of the upper lobe abdominal breathing
What respiratory consequences does decreased ribcage stability have?
Decreased structural support for the respiratory muscles to work from
What does the soda can model of respiratory and postural control mean?
- Structurally weak, yet functionally strong
- Unopened, very strong because pressure is exerted
- Opened becomes weak; Structural integrity of thorax not inherently strong; Spine and rib cage not able to maintain alignment
- Muscular support is required to help “close the can”
- Thoracic and abdominal chambers separated by diaphragm
- m support allows increases in internal pressure to withstand external forces
What muscles, when contracted, can increase thoracic and abdominal pressures?
- intercostals
- diaphragm
- back extensors
- abdominals (transverse abdominus)
What happens when the diaphragm contracts and inspires?
- Diaphragm contracts and central tendon descends; Create negative pressure in the thoracic cavity; Intercostals contract to prevent inward pull of negative pressure
- As diaphragm continues to contract; Abdominal pressure rises; There is equal negative pressure in the thoracic to the positive pressure in the abdominal pressure (absolute value)
- diaphragm plays less recognized role in trunk stability but creates pressure differences in cavities
What forms the superior pressure valve?
the glottis
- important for talking and coughing
- If compromised, there is not way to control positive pressure created upon inspiration.
- Impairments in the glottis may result in speech or eccentric motor impairment
What forms the inferior support of the “soda can”?
pelvic floor muscles
- If muscles are injured or ineffective, they will allow pressure to be released via the pelvic opening - Urinary stress incontinence; Less productive cough or sneeze
- Muscles are often affected after childbirth - Crossing legs is a compensatory support mechanism; LBP often decreases pelvic floor functioning
