Chp 21 Posture Flashcards
Decreased thoracic curve
Flat back
Increased lumbar curve is known as
Sway back
In most cases if there is an increase in lumbar curve there is
also an increase in thracic curve
At birth the entire vertebral column is flexed and aneriorly concaved. This concave curve is called
primary curve
The lateral pelvic tilt is controlled by these muscles:
Abductors: gluteus min and medius
Trunk lateral benders: QL and erector spinae
Force couple keeps pelvis level in the frontal plane. In a reversal of muscle action:
the lateral benders pull up while the right hip abductors pull down.
This will result if legs are not of equal length
scoliosis
These two group of muscles are important in controlling postural sway:
Plantarflexors and dorsiflexors
Plumb line should be aligned in this fashion when assessing posture:
anterior to lateral malleolus posterior to patella through greater trochanter through lumbar bodies through acromion process through earlobe
Three tasks associated with the two phases of gait cycle: what are the tasks and what are the two cycles
Cycles: stance and Swing
Tasks: 1st - Weight acceptance
2nd - Single limb support
3rd - Limb advancement
When walking slowly you spend more or less time in double support
More
Nonsupport occurs when?
When both feet are off the ground at same time as in jogging or running
What are the Rancho Los Amigos comparative terms for these traditional terms in relation to gait terminology: Heel Strike Foot flat Midstance Heel-off Toe-off
Heel Strike = initial contact Foot flat = Loading response Midstance = midstance Heel-off = Terminal stance Toe-off = Preswing
Traditional language vs Rancho Los Amigos for Swing phase
Accelerate = Initial swing Midswing = Midswing Deceleratiom = Terminal swing
Vertical displacement is greatest during _____ and lowest at ____ during normal gait pattern.
Midstance
Heel strike
