What are the 3 principles of seating intervention
- Adjunct to treatment
- Postural control vs. Pressure distribution
- Dynamic vs. Static
According to the seating intervention “Adjunct to treatment” - seating & mobility interventions should…
- meet individual’s needs
- monitor problems & effectiveness of solutions over time
- In consultation with primary care therapists & others involved in individual’s care
According to the seating intervention “ Postural control vs. Pressure distribution”, seating and mobility interventions should…
- Improve postural control
- Optimize pressure distribution over body’s weight-bearing surfaces
What is postural control
Motor control that stabilizes thebody in space by integrating sensory input about body position with motor output to coordinate the action of muscles & keep the body’s COM within its BOS
Good postural control will allow optimal ___ and reduce ____
function fatigue
What is pressure
a force that is exerted perpendicular to the skin surface
what is friction
the resistance to motion in a parallel direction relative to the common boundary of two surfaces
What is shear
A stress resulting from applied forces that causes two layers of skin tissues to slide in opposite but parallel planes
To reduce risks of pressure injury development, focus on…
- Pressure
- Shear
- Friction
- Temperature
- Moisture management
If a pressure injury lasts more than… red flag
20 minutes
_____ or _____ keep us up against gravity and do not fatigue easily
Postural muscles or stabilizers
___ or _____ help us to move quickly and precisely
Mobility muscles or mobilizers
What are 6 risk factors related to skin health
- health status
- Nutrition
- Skin integrity
- Immobility
- Sensation
- Continence
What is the order of observation
- Pelvis
- Hips
- Lower extremities
- Trunk
- Head/neck
- upper extremities
What are some common components of a wheelchairs
- Firm base
- Firm back
- Ischial block/well
- Belt
Why is an ischial block importnat
With altered tone or movement problems cause a posterior tilt which causes people to slide right off cushion
What are 3 types of belt?
- Standard
- Bifurcate
- Molded
What are some potential consequences of postural problems
- Tissue breakdown
- Contracture/deformity
- Altered performance
- Reduced tolerance
- Discomfort & fatigue
- Increased need for rest
- Infection
- Decreased quality of life
- Increase need for care
- increased cost of care
when would you use a firm back or base?
??? idk help
What are 4 common postural problems
- Posterior pelvic tilt
- Anterior pelvic tilt
- Pelvic obliquity
- Pelvic rotation
What may cause posterior pelvic tilt
- Poor back or seat surface support
- Tight hamstring muscles
- Limited hip flexion
What are some solutions to posterior pelvic tilt
- Firm backrest + firm seat
- Anti-thrust seat
- Supportive belts
- Support at the posterior pelvis/lower lumbar area
What are some possible causes of anterior pelvic tilt
- Footrests set too far back
- hip flexion contracture
- Weak back extensors
- Weak abdominals
What are some solutions to anterior pelvic tilt
- Adjust footrests
- Firm backrest and firm seat
- Change seat to back angle or orientation in space
