19
Q

Each gait cycle has two periods of _______ support and two periods of ________ support

A
  • double
  • single
20
Q

When both feet are in contact with the ground, this is a period of ?

  • When one leg is beginning stance phase and the other one is ending stance phase (there are two of these periods)
A

double support

21
Q

Each period of double support will take up about ___%of the gait cycle (_____%all together)

A

10%

20%

22
Q

If you increase your walking speed, you spend less time or more time in double support?

A

less time

23
Q
  • Occurs when neither foot is on the ground
  • this period is the biggest difference between these two activities
A

Nonsupport Period

24
Q
  • Occurs when only one foot is in contact with the ground
  • Two periods of this support occurs in a gait cycle
A

Single Support

25
Q

Two periods of single support occur in a gait cycle?

A
  • Once when the R foot is on the ground and once when the L foot is on the ground (the opposite foot will be in swing phase)
  • Each single support phase takes up about 40% of the gait cycle
26
Q

Traditional vs. Ranchos Los Amigos 
should be interchangable

**traditional **

  1. Heel strike
  2. Foot flat
  3. Midstance
  4. Heel – Off
  5. Toe – Off
  6. Acceleration
  7. Midswing
  8. Deceleration
A

Ranchos Los Amigos

  1. Initial contact
  2. Loading response
  3. Midstance
  4. Terminal stance
  5. Preswing
  6. Initial swing
  7. Midswing
  8. Terminal Swing
27
Q
  1. Traditional = describes ?
  2. Rancho = describes?

Most have a beginning point and an end point (Table 22-1)

A
  1. points in time
  2. periods of time
28
Q

Stance Phase: Traditional

Heel strike – heel contacts the ground

Foot flat – Plantar surface of the foot in contact with the ground

Compare to RLA

A

RLA

Loading Response –

  • Beginning – just after IC when the body weight is being transferred onto the leg and entire foot makes contact with the ground
  • Ending – opposite foot leaves the ground
29
Q

Stance Phase

Traditional

Midstance – point at which the body passes over the weight bearing leg

Heel Off – heel leaves the ground while the ball of the foot and toes remain in contact with the ground

Compare to RLA

A

Stance Phase

RLA

Midstance
Beginning – opposite foot leaves the ground
Ending – body is directly over the weight bearing limb

Terminal Stance
Beginning – as the heel of the weight bearing leg rises
Ending – IC of the opposite foot and the body has moved in front of the weight bearing leg

30
Q

Stance Phase

Traditional

Toe Off – Toes leave the ground, ending stance phase

compare to RLA

A

Stance Phase

RLA

Preswing –

Beginning – initial contact and weight shifted onto the opposite leg

Ending – just before the toes of weight bearing leg leave the ground

31
Q

Swing Phase

Traditional

Acceleration – the swing leg begins to move forward

compare to RLA

A

RLA

  • *Initial Swing –**
  • *Beginning** – the toes leave the ground
  • *Ending** – the swing foot is opposite the weight bearing foot and the knee is in maximum flexion
32
Q

Swing Phase

Traditional

Midswing – the swing (non weight bearing) leg is directly under the body

compare to RLA

A

RLA

Midswing –
Beginning
– the swing foot is opposite the weight bearing foot
Ending – the swing leg has moved in front of the body and the tibia is in a vertical position

33
Q

Swing Phase

Traditional

Deceleration – The leg is slowing down in preparation for heel strike

compare to RLA

A

RLA

Terminal Swing –
Beginning
– the tibia is in a vertical position
Ending – just prior to initial contact
