Q

What are primitive reflexes?

A

Differ from spontaneous movement in that they are a response to a specific stimuli, they are localized, and the stimulus will elicit the same reflex over and over again

Q

What is a motor milestone?

A

A fundamental motor skill, the attainment of which is associated with the acquistion of later voluntary movements. The order in which an infant attains these milestones is relatively consistent, although the timing differs among individuals.

Q

What is locomotion?

A

Is the act of moving, or the capability to move, from place to place - a complex activity that involves many interacting systems and constraints

Q

These types of movements occur when all four limbs are in contact with the supporting surface…

A

Creeping and crawling

22
Q

What does creeping entail?

A

Moving on hands and knees

23
Q

What does crawling entail?

A

Moving on hands and abdomen

24
Q

Walking is defined as the following:

A

50% phasing between legs and period of double support (both feet on the ground) followed by a period of single support

25
Q

Feet are out-toed, no trunk rotation, arms are high in guard are examples of what type of walking?

A

Early walking

26
Q

When stability and balance are maximized over mobility, what kind of walking is this?

A

Early walking

27
Q

Stride length increases, opposition of arms and legs occurs, out-toeing is reduced are examples of what type of walking?

A

Proficient walking

28
Q

When stability is traded for mobility, what kind of walking is this?

A

Proficient walking

29
Q

What are the two rate limiters in early walking?

A
  1. Legs must be able to move alternately and enough strength to support on a single limb
  2. Must be able to balance on one leg while transferring the weight to the other foot
30
Q

Support time on the stance leg lengthens and velocity increases, which developmental change is this?

A

Early childhood development change

31
Q

Stride length increases with fuller range of motion and pattern improvements are subtle, which developmental change is this?

A

Mid-adolescence developmental change

32
Q

Stability is maximized, pelvic rotation decreases, and speed decreases, which developmental change is this?

A

Later adulthood developmental change

33
Q

When does running typically occur?

A

Occurs 6-7 months after walking starts

34
Q

How is running defined?

A

Like walking, it has a 50% phasing realtionship between legs; Unlike walking, running has a period of flight, during which neither foot is in contact with the ground

35
Q

Stability over mobility, arms are in high guard, limited ROM, short stride length, and flat foot are examples of what type of running?

A

Early running

36
Q

What are the rate limiters of early running?

A

Must have proficient strength in each leg to lift off the ground; once in the air, infants must catch themselves on the other foot and balance on that leg while shift their weight forward

37
Q

Less stability and more mobility, increased stride length, narrow based support are examples of what type of running?

A

Proficient running

38
Q

What are the rate controllers in later running?

A

Running requires greater generation of force and ability to balance than walking; Running form can continue to be refined

39
Q

What are the early characteristics to early jumping?

A

Jumping only vertically, one-foot takeoff or landing, no or limited preparatory movements

40
Q

What are the characteristics to proficient jumping?

A

Both feet leave the ground at the same time, arm swing during jump, can jump vertically and horizontally

41
Q

What is the rate limiter in jumping?

A

Developments of enough force to bring own body into the air from a still postion

42
Q

What are the characteristics of early hopping?

A

Support leg is lifted rather than used to project body, arms are inactive, swing leg is held rigidly in front of the body

43
Q

What are the characteristics of proficient hopping?

A

Swing leg leads hip and moves through full range motion, support leg extends fully at the hip, oppostional arm movement, support leg is flexed for landing absorption

44
Q

What are the developmental changes in hopping?

A

Nondominant leg is slower to development, adaptations of the neuromuscular system moderates the force of landing

45
Q

What are the rate controllers in hopping?

A

Depends on the postural system’s ability to balance the body on one limb for a succession of hops; ability to generate enough force to lift the body with one limb, recover, and quickly generate enough force to hop again

46
Q

What type of movement is a forward step on one foot and a leap on the other?

A

Gallop

47
Q

What type of movement is a sideways step and a leap on the other?

A

Slide

48
Q

Arrhythmic and stiff movements, little or no arm movements, little or no trunk rotation, and short strides are characteristics to what?

A

Early galloping, sliding, and skipping

49
Q

The arms are no longer needed for balance, arms swing rhythmically in opposition to legs and provide momentum are two characteristics of what?

A

Proficient galloping, sliding, and skipping

50
Q

In what order do sliding, skipping, and galloping emerge in developmental changes?

A

Galloping is the first to emerge, sliding is second, and skipping is usually the last to emerge

51
Q

What is the most common rate limiter between galloping, sliding, and skipping?

A

Coordination
