week 1 Flashcards
common types of assistive technology
- mobility devices
- positioning devices
- orthosis, prosthetics, and orthopedic shoes
mobility devices examples
- wheelchairs
- tricycles
- walker
- canes/walking sticks
- walkers/walking frames
causes for requiring assistive devices
- compensation
- improve functional mobility
- enhance body functions
- assist fracture healing
compensation
- impaired balance
- decreased balance
- altered coordination
- pain during weight bearing
- absence of extremity
- altered stability
- initial contact to foot flat. what muscle?
- purpose
- gluteus maximus
- stabilize limb
- terminal stance to pre-swing. what muscle?
- purpose
- gluteus medius/minimus
- stabilize the pelvis in frontal plane
- preswing to mid swing. what muscle?
- purpose
- hip flexors
- accelerate limb
- loading response. what muscle?
- purpose
- quadriceps
- absorb shock, eccentric contraction, stabilizes the knee
- mid swing to initial contact. what muscle?
- purpose?
- hamstrings
- decelerate limb
- initial contact to midstance and pre swing to initial contact. what muscle?
- purpose
- tibialis anterior and peroneals
2.absorb shock, elevate foot
- midstance, terminal stance to preswing. what muscle?
- purpose
- gastrocnemius/soleus
- knee stability at terminal stance, push off
- initial contact to initial contact. what muscle?
- purpose
- erector spinae
- stabilized the trunk
major muscle groups used for non-weight bearing ambulation. upper trunk
scapular depressors, scapular stabilizers
major muscle groups used for non-weight bearing ambulation.
lower trunk
trunk extensors and flexors
major muscle groups used for non-weight bearing ambulation.
upper extremity
shoulder depressors, shoulder extensors & flexors, elbow extensors, and finger flexors
major muscle groups used for non-weight bearing ambulation.
weight-bearing lower extremity.
- hip abductors
- hip extensors
- hip flexors
- knee flexors
- knee extensors
- ankle dorsiflexors
- plantar flexors
most common muscle used for crutches
latissimus dorsi
in order to propel the assistive device. help LE to move
scapular stabilizers= rotator cuff muscles
more stable assistive devices
walkers
three major categories of assistive devices
- canes
- crutches
- walkers
there are no restrictions on weight bearing; 100% of body weight can be borne on the LE .
full-weight bearing
no weight is borne on the involved limb; foot/toes make no contact with floor/ground surface.
non-weight bearing
only a portion of weight can be borne on the extremity; sometimes expressed as a percentage of body weight
partial weight bearing
only the toes of the affected extremity contact the floor to improve balance (not to support the body weight)
toe-touch weight bearing/ or touch-down weight bearing
weight bearing is limited by patient tolerance of weight borne on extremity
weight bearing as tolerated
categories of assistive devices ranked from highest to lowest supporting magnitude
- walkers
- bilateral crutches
- single crutch
- bilateral canes
- quad canes
- hemi cane
- single cane
