Q

Where is the vertical midline with quiet stance?

A

Q

What can alignment minimize?

A

the effect of gravitational forces which can pull off center

20
Q

What is required to keep the body upright against gravity?

A

a certain level of muscle tone

21
Q

There is a considerable amount of variability in seated alignment particullary in the _________ plane

A

sagittal

22
Q

What kind of posture do a lot of adults assume when seated?

A

kyphotic posture

23
Q

What will cause muscle activity to vary with sitting?

A
  • location and degree of external support
24
Q

________ is not controlled as a single segment and required a complex coordination of muscle activity

A

Trunk

25
Q

What is “ an important mobility skill because of rotation or partial rotation being a part of other movement patterns”

A

ROLLING

26
Q

What do we need rolling for?

A

supine to sit and getting out of bed

27
Q

What happens to rolling patter as humans mature?

A

goes from log roll to a segmental rolling pattern

28
Q

What is the most common pattern used by adults to move from supine to prone?

A
  • The shoulder girdle initiates the movement with a lift and reach pattern along with the head and trunk and unilateral lift of the leg
29
Q

What should we do when reteaching rolling as a therapist?

A

use variability!!!!

30
Q

What does the inability to go from supine to standing cause?

A

represents a pbarrier to recovery of normal function

31
Q

What are the variants to be able to go from supine to standing?

A
  1. momentum to move the body to vertical
  2. stability to control the COM as it changes BOS from supine to eventually standing
  3. ability to adapt according to the changing environment
32
Q

What is a common pattern for supine to standing?

A
  • pushing with the arms at the side of the bed, flexing the head and trunk, pushing into partial sit and rolling up into stance
  • sacrifices stability
33
Q

What is the push off pattern for supine to standing?

A

rolling to the side and coming to a symmetrical sitting position prior to standing

  • harder to generate but gives greater stability
34
Q

As infants how do we get from supine to standing (from floor)?

A

as infants we use a prone to quadruped technique then pulling

35
Q

What age do we start using an adult like symmetrical pattern when going from supine to standing from the floor?

A

by age 4-5

36
Q

What are 3 common mature patters for supine to stand from the floor for neurologically intact individuals?

A
  1. symmetrical movement pattern of the trunk and extremities and assuming a symmetrical squat to come to a vertical
  2. same as above but asymmetric squat on rising
  3. asymmetric use of the UEs, partial rotation of the trunk then coming to half kneel
37
Q

What influences the strategy someone will use when going from supine to standing from the floor?

A
  • ability to generate force and strength spefically in the abdominals and hip flexors
38
Q

What is sitting to standing dependent on?

A
  • generating enough torque needed to rise
  • ensuring stability by moving the COM from the chair/surface to the feet
  • the ability to modify strategies depending on the environment (chair height, armrests, compliant surface)
39
Q

What is the first phase of the common 4 phase technique for sitting to standing?

A
  1. weight shift or flexion momentum phase-forward momentum of the upper body through flexion of the trunk. erector spinae contract eccentrically to control
40
Q

What is the 2nd phase of the common 4 phase technique for sitting to standing?

A
  1. begins when the bottom leaves the seat and there is a transfer of momentum from upper body to total body. Horizontal and vertical of the body. Inherently unstable and requires co-contraction of hip and knee extensors
41
Q

What is the 3rd phase of the common 4 phase technique for sitting to standing?

A
  1. lift of extension phase - extension of the hips and knees and goal is for the body to move forward
42
Q

What is the 4th phase of the common 4 phase technique for sitting to standing?

A
  1. stabilization - extension is complete and body is stabilized
43
Q

What force is used in the momentum strategy for sitting to standing?

A

less stable but more force is used to stand

44
Q

What does the momentum strategy for sitting to standing require?

A
  • strength and coordination to generate upper body force prior to lift off
  • the ability to eccentrically contract trunk and hip muscles to slow the horizontal movement of the COM
  • concentric contraction of hip and knees to generate force to lift the body
45
Q

What is the zero momentum strategy for sitting to standing?

A

alternative is to add stability but must be able to generate enough force to achieve lift off

46
Q

What does the zero momentum strategy require?

A
  • flexing the trunk to bring the COM well within the BOS of the feet
  • LE forces to lift off the body
