Q

How growth and maturation influence changes in motor behavior

A

Motor development

Babys mature and continue maturing until they get old

So its not just babys turning into adults, but adults also turning into elderly (so eventually it develops in a degenerative kind of way)

Q

Why does motor control change w/ aging?

A

Motor control is the activation and coordination of msucles and limbs involved in the performance of a motor skill

As we age we lose myelination / efficency so our motor contorl decreases

Q

KNOW: Motor skill = Motor action

Every motor skill must have a reason to be used (goal to achieve)

Every motor skill must be performed voluntarily (not reflexive)

Must require movements of joints / body segments

Must be learned or relearned (because its a skill)

Q

If were moving from the front of the room to the back of the room and the room is empty do we have more feedforward or feedback?

A

Feedback (because we don’t need much anticiptory)

  • if the environment is stable you don’t need to worry about making adjustments to whats around you as much

25
When drinking water do we use more feedforward or feedback?
feedforward (anticipatory) because we don't want to dump it on ourselves
26
When standing up from a moving bus do we need more feedfoward or feedback?
Feedback Theres no way to anticipate it if its moving so you're going to need to correct yourself if thrown off balance
27
Define gross motor skills
Things only involving larger muscles (think walking / sit to stand etc.)
28
Define fine motor skill
Things that use small muscles (typing, texting)
29
Is throwing a baseball a fine motor skill or a gross motor skill?
Both Fine = grip Gross = the arm movement to throw it / leg stance
30
Define continous motor skills Give examples
Things with random beginning and ends Steering a car, walking, swimming Often are random movements
31
Define discrete movements. give examples
Things with very specific beginnings and very specific ends Turning on a light switch, hitting a piano key Single movement not a repetitive movement
32
Are repeptive movements discrete or continuous
continuous (think swimming) - very random stop and start
33
What are serial movements? Give an example
continuous series of discrete movements Playing a song on piano. Were pressing lots of keys (each key = discrete movement) to make up one long random continuous song. It has an aspect of repetitiveness (**hitting keys over and over but hitting each key has a distinct beginning and end)**
34
define open motor skills Is it more or less predictable?
things are happening around a system - the system is not contained EX: you're walking on a sidewalk and other things are moving (people walking past you) Less predictable
35
Define a closed motor skill More or less predictable?
Everything is more stationary Picking up a cut or shooting a free throw - not much is moving around you (not much variation) More predictable
36
Is walking up 3 stairs then back down discrete or continuous?
Discrete Theres a specific start and stop
37
I want you to walk up and down this flight of stairs until I tell you to stop. Is this discrete or cintuous motor skills?
Continuous (because its an arbitray [random] start or stop)
38
is a stationary environment open or closed?
Closed
39
Explain a stationary environment with variability vs without variability
Without variability means that same static environment where the patient steps up and down off the same step length every time we do it **(the environment is still closed and things in the environment are all the same [step height is the same everywhere])** Stationary environment without variability means that patient is stepping on steps that are different sizes **(the environment itself is still closed but the thing in the environment are different)**
40
What does in-motion conditions mean?
The environment moves itself
41
Compare and contrast in-motion conditions with variability vs without variability
With variability: environment is moving itself (constant treadmil pace) Without variability: environment is moving itself in a variabile way (treadmill changing spreeds)
42
Object manipulation =object is moving
43
Give an example of No object manipulation, stationary conditions and no internal variability
Standing alone in a room Holding a yoga pose
44
Give an example of stationary conditions, with variability and no object manipulation
Standing on different surfaces
45
what is the general **trait or capacity of an individual** that determines a person's potential to achieve and perform a specific skill?
Ability trait = being tall to play basketball
46
Ability that is specifically realted to the performance of a motor skill
Motor ability ability to perform the motor skill (Dr. V. can play basketball so she has the motor skill - just not to do it at a very high level)
47
Many different motor abilities that exist in an individual are highly related and can be characeterized in terms of a singular, global motor ability is general motor ability hypothesis or specificity of motor abilities hypothesis
it was disproven general motor ability hypothesis made because some people just seem to be good at everything (think they developed on skill that allowed them to do anything - however this is not true)
48
The many motor abilities in an individual are relatively independent. Is this genreal motor ability hypothesis or specificity of motor abilities hypothesis.
specificicity of motor abilities hypothesis (true) motor abilities are all relatively independent. That person who is good at all sports has developed the motor pathways that will allow them to be good at all these similar activities. If they had only focused on one particular sport we wouldnt see that much carrier over This shows us motor pathways are relatively independent
49
Postural stability =
balance
50
What 3 things impact motor ability?
Balance Timing Visual input
51
Internal timer is super important for activites (can be messed up with stroke). What would we use if their internal timer is messed up?
An external timer Something that forces things in the skill to be done at the correct time but is outside the body
52
Is walking with the patient an external or internal timer?
External (you're pacing them)
53
can vision have an impact on how fast someone can learn a motor skill?
Yes

68
Explain a stationary environment
when the environment is moving (BUT YOU CAN STILL BE MOVING) Think walking in a hallway where nothing else is moving
69
Explain internal variability
whether the regulatory conditions (environment) is the same or different from trial to trial None = person walks through uncluttered room several times Yes = someone walks through a room several times when the objects are moved around from time to time
70
Shooting a free throw in basketball Stationary or in motion Internal varbaility or No internal varbaility
Stationary (nothing in the environment is moving) No internal varbaility (everytime you go to shoot a freethrow its from the same spot with same environment from trial to trial)
71
Walking in an uncluttered hallway Stationary or in motion conditions Varbaibilty or none
Stationary (even though you are walking your environment is not moving) Varbiaility - none = you are walking down the same hallway over and over and nothing changes
72
Golf shots during a around of gold (so all the shots you hit throughout the game) Stationary or in motion
Stiationary (you're hitting at the hole - nothing is moving in the environment) Variablility = yes = every different shot is from a different place so there is variability
73
Taking several drinks of water from the same glass Stationary or in motion Variabile or none
Stationary - everything moving in the envuironment you're causing to move (environment not moving on its own) Variable = every time you drink from that glass the water level is different meaning you need to put it up to your mouth with different force everytime
74
Hitting tennis balls projected at the same speed form a ball machine Stationary or in motion Vairable or none
In motion (the environment is moving - you're not causing the balls to be shot at you No variability - its the same hit everytime - nothing is changing from tiral too trial
75
Walking on a treadmil at a constant speed Stationary / In-motion Variabile / none
In-motion (you're not causing the surface below you to move) No vairability (the treadmil at the same constant speed form trial to trial)
76
