33
Q

drawing toes back towards shins is called:

A

dorsiflexion

34
Q

pointing your toes is called:

A

plantar flexion

35
Q

dorsiflexion is (EXTENSION/FLEXION)

A

EXTENSION

36
Q

plantar flexion is (FLEXION/ EXTENSION)

A

FLEXION

37
Q

what is the embryologically-ventral surface of the FOOT?

A

plantar aspect

38
Q

what is the embryologically-ventral surface of the LEG?

A

posterior calf

39
Q

inversion of foot is similar to (SUPINATION/PRONATION)

A

supination (towards midline)

40
Q

eversion of foot is similar to (SUPINATION/PRONATION)

A

pronation (away from midline)

41
Q

axis of rotation for abduction/adduction of the toes is what?

A

2ND DIGIT

42
Q

where is center of gravity located?

A

midsagittally and slightly anterior to 2nd sacral vertebrae

43
Q

where does line of gravity lie in relation to hip, knee and ankle joints?

A
  1. Hip - sl posterior to hip joint
  2. Knee - anterior to knee
  3. Ankle - anterior to ankle by ~2 inches
44
Q

Line of gravity tends to convey the following effects at the hip, knee, and ankle joints:

A

1) Hyperextend the hip
2) Hyperextend the knee (bc anterior to the transverse)
3) dorsiflex the ankle

45
Q

what muscle(s) limit HIP HYPEREXTENSION?

A

2 muscles

  • Iliofemoral ligament (Y ligament of Bigelow)
  • Ischiofemoral ligament
46
Q

what muscle(s) limit KNEE HYPEREXTENSION?

A
  1. intracapsular/extracapsular ligaments providing posterior support
  2. gastrocnemius
47
Q

what muslce(s) limit ankle dorsiflexion?

A

active plantar flexors (i.e. Triceps surae, which is the gastrocnemius and soleus muscles)

48
Q

What defines a gait cycle?

A

one stride or 2 steps

49
Q

traditional gait cycle (order) - stance phase

A
  1. initial contact /heel strike (0%)
  2. foot flat (7%)
  3. midstance (30%)
  4. heel off (40%)
  5. toe off (60%)
50
Q

traditional gait cycle (swing phase) - order

A
  1. acceleration
  2. midswing
  3. deceleration
51
Q

which forces act together to form the Ground Reaction Force (GRF)?

A
  1. gravitational
  2. muscular
  3. momentum
52
Q

which force(s) act together during standing?

A

just gravitational force

53
Q

during which phases in stance phase have GRF forces pointing UPWARDS?

A

initial contact, midstance, toe off

54
Q

during which of the stance phase is the GRF line pointing down towards the ground?

A

flat foot, heel off

55
Q

which muscle groups are recruited at each joint to offset GRF during INITIAL CONTACT/HEEL STRIKE?

A
  1. At hip - hip extensors
  2. At knee - knee extensors
  3. At ankle - ankle dorsiflexors
56
Q

which muscle groups are recruited at each joint to offset GRF during MIDSTRIKE (one limb off the ground)?

A
  1. Hip abductors (gluteus maximus/minimus) - on the stance side prevents the pelvis on the swing side from sagging
  2. Knee extensors are active
  3. Plantar flexors stabilize the ankle
57
Q

define compensatory trendelenburg gait

A

*Gait functions as ABDUCTORS that are not working
• Trendelenburg test/sign to see if there is drooping on the opposite side; pt may fall or need to grab the table

58
Q

compensatory trendelenburg gait: for left side is affected

A

No pelvix drop/tilt on right side while the right limb is in the swing phase; trunk shifted to the left

59
Q

which muscle groups are recruited at each joint to offset GRF during TOE-OFF?

A
  1. Hip - hip flexors
  2. Knee - knee extensors
  3. Ankle - ankle plantar flexors
60
Q

CC: apropulsive or calcaneal gait

A

weakness of the ankle plantar flexors can result in insufficient propulsion;

there will be no toe-off, but the entire foot will leave the ground at once
