Q

How our neuromuscular system functions to activate and coordinate the muscles and limbs involved in the performance of a motor skill.

A

Motor Control

● Kung di mo naman siya ma coordinate ng
maayos, nonsense din kasi di mo naman ma
control yung movement mo
● You need to have a good motor control to be
able to do the types of movement u want
● Anything u do without coordination is magulo

Q

How does motor control work?

A
  1. The task that needs to be completed is identified →
    body gathers sensory info from environment (afferent) → perceives info → chooses a movement plan
    appropriate plan to meet the goal of the task
    E.g. may sunog, you have to move away from that
  2. Plan is coordinated w/in CNS → executed through
    motor neurons in the brain and SC → outcome
    communicated to the muscles in postural and limb synergies, and in the head and neck (efferent)→ motor units timed to fire in a specific manner
  3. Sensory feedback supplied to the CNS by the movement → decision taken to (1) modify the plan during execution, (2) acknowledge the goal of the task to be achieved, and (3) store the information for future performance of the same task-goal combination
    (- Can you modify the plan during execution? It
    depends sa situation, may kailangan ka ba
    i-modify or hindi.
    - You have to store for future references para
    makita mo if may mali or tama. If may mali,
    you use that knowledge to correct yung mali
    mo sa movement)

Q

➔ The afferent-efferent interaction lang
➔ Movement is initiated and withdraw upon by a certain
stimulus
➔ A reaction is equated to an action – kung ano nararamdaman mo, you’ll react to it
◆ You react to the stimuli around you
➔ You use sensory input to stimulate you to move
➔ Relies heavily on feedback
(Kidlat - stimulus → afferent → efferent)

environment. How things react to you and
how you react to things

A

DYNAMIC SYSTEMS THEORY

◆ E.g. pag mahina yung katawan → sa sit and
stand pag ginamit ng pt yung momentum for
standing up, mas madadalian siya tumayo,
compared pag stable siya tas papatayuin mo
siya nng upright.
◆ Kunin yung momentum mas madali siya
makakatayo kaysa na bigla mo siya
papatayuin

➔ Nakaprogram dapat lahat ng movement mo
➔ May ayos dapat yun kung pano yung gagawin na
movement
➔ Kailangan tama yung coordinated movement → teach
pt na ma re-learn yung right pattern of movement
➔ E.g. kailangan matuto ung biceps na mag work siya
kahit walang ibang mm grp, to complete a certain movement. Then after niya matuto na siya lang, teach
it na mag coordinate c other mm groups, to achieve
certain tasks

Q

2 important goals to achieve Initial stage of learning:

A

1) Acquire a movement pattern that will allow some
degree of success at achieving the action of the goal
of the skill

2) Learn to discriminate between regulatory and
nonregulatory conditions in the environmental
context in which he/she performs the skill

41
Q

Describe Acquire a movement pattern that will allow some degree of success at achieving the action of the goal of the skill

A

◆ Beginner must develop movement
characteristics that match the regulatory
condition of the environmental context in
which the skill is performed

42
Q

Describe the 2 Learn to discriminate between regulatory and nonregulatory conditions in the environmental
context in which he/she performs the skill

A 
◆ Regulatory conditions refer to those
characteristics of the environmental context
to which movement characteristics must
conform if the action goal is to be
accomplished
>E.g. nag aaral siya mag grasp ng
certain things → kailangan niya
muna maangat ung hand niya
before he can proceed to grasping
◆ Non regulatory conditions are
characteristics of the performance
environment that have no influence or only
an indirect influence on the movement
characteristics required to achieve an action
goal
> E.g. reaching and grasping a bottle
and controller. Goal: to grasp.
> How u will reach or attain that goal
to grasp the bottle
> Ano shape nung bote, anong kulay
nung bote, cinoconsider mo yun
43
Q

What is Later stages of learning

A

➔ Learner works to achieve three important goals
➔ First, the person must develop the capability of
adapting the movement pattern to the specific
demands of any performance situation requiring that
skill
◆ Develop capability of adapting the movement
pattern to specific demands of any
performance situation requiring that skill

➔ Second, the person must increase his/her consistency
in achieving the goal of the skill
◆ Kailangan you practice it to be more
consistent

➔ Third, the person must learn to perform the skill c an
economy of effort
◆ Economy of effort - efficient movement

44
Q

the learner’s goal in the 2nd stage of learning
in Gentile’s model for learning closed skills in which
learners refine movement patterns so that they can
produce them correctly, consistently, and efficiently from trial to trial.
the learner will experience in his or her
everyday world or in the environment in which he/she will perform the skill

A

➔ Fixation

◆ E.g. reaching, grasping and drinking from a variety
of shapes and sizes (ex. bote)
◆ Shooting basketball free throws as it would occur
in the game (iba kasi ung shooting sa practice lang
compared sa game)

45
Q

the learner’s goal in the 2nd stage of learning in Gentile’s model for learning open skills in
which learners acquire the capability to modify the
movement pattern according to environmental context
characteristics

A

➔ Diversification -

46
Q

include characteristics as similar as

possible to those

A

➔ Closed skills

47
Q

systematically vary the controllable
regulatory conditions of actual performance situations,
while allowing naturally varying characteristics to occur as they normally would

A

➔ Open skills:

◆ E.g. walking from one end of the hallway while
various people are walking in different directions
and speed
◆ (e.g. paglalakad sa mall, challenge na siya for pts
kasi icconsider mo ung speed, ung dami ng tao,
etc)

48
Q

➔ PT should demonstrate the task (modeling) exactly as it should be done

A

Strategy Development

◆ Show the pt how the exercise is done
properly, at first.
◆ Sobrang importante na tama ung exercise na
ginagawa mo kasi pag ginawa ni pt tas mali
edi wala rin.
◆ Sobrang importante ng form ng body sa
exercise → pag mali ung form → results in
compensation and doing the exercise wrong
(activates others mm kaysa ung target mm
dapat)
◆ Force distribution

49
Q

Strategy Development
Explain
➔ The PT should highlight the purpose of skill in a
functionally relevant context

A 
◆ Explain to your pt kung anong gagawin
◆ Mas maganda na involved ung pt sa
treatment plan
◆ Para aware siya kung ano ung tinatarget
niya, kaya siya magkakaroon ng goal and
target
50
Q

Strategy Development
Explain
➔ Task should seem important, desirable, and realistic to learn

A

◆ Pag magpapagawa ng task dapat
appropriate doon for the pt (dapat realistic)
◆ E.g. u want the pt to walk pero di pa pala
nakakatayo
◆ When you’re planning a goal, apply SMART

51
Q

Strategy Development
Explain
➔ Highly skilled individuals who have been successfully
discharged from rehabilitation can be expert models

A

◆ E.g. may stroke pt ka na gumaling na with
this exercise– use him/her as an example to
motivate your current patient
◆ Pakita mo pano gagawin

52
Q

Strategy Development

involves physically assisting the
learner through the task to be learned

A

➔ Guided movement

◆ During the guided movement, make sure na
maayos ung form na pinapagawa mo
◆ Overuse of guided movement is likely to
result in overdependence
● There is a certain time na dapat
alam mo kailan ka mag sstop sa
guided movement
● E.g. AAROM
53
Q

the ability to maintain consistency in performing

functional tasks with economy of effort

A

➔ Skill:

◆ Pinagsama na yung mobility, stability and
controlled mobility c
◆ Combination of the three (stability, mobility and
controlled mobility)
◆ Skill is the highest level

54
Q

➔ The key to success in using guided movement is to
limit guidance and intersperse practice with active
movements as soon and as much as possible
➔ During initial practice, the therapist should provide
precise feedback, highlighting information critical for
movement efficiency
➔ The therapist should NOT attempt to correct all the
numerous errors that characterize this stage but rather
allow for trial-and-error learning.

A

Strategy Development

55
Q

Feedback

occurring as a natural result of the movement

A

➔ Intrinsic (inherent) feedback

◆ E.g. proprioceptive, visual, vestibular, and
cutaneous
◆ Kung ano lang meron sa environment mo
yun lang yun

56
Q

Feedback

incorporating sensory cues provided that are not normally received during the movement

A

➔ Extrinsic (augmented) feedback)

◆ Example: visual, auditory, and tactile cues
are forms of extrinsic feedback
◆ E.g. i’ll use a marker to mark you destination
o kaya kailangan eto lang ung ma r-reach mo
(may visual feedback)

57
Q

Feedback

augmented feedback about the nature of the end result
produced in relation to the goal

A

◆ Knowledge of result (KR) -

● successful or hindi successful

58
Q

Feedback

augmented feedback about the nature or quality of the
movement pattern produced

A

◆ Knowledge of performance

● E.g. hindi successful, so bakit?
Siguro mali ung pattern of
movement, o di nakatayo agad

59
Q

Feedback is presented during the movement;
KP information is provided (e.g., information
about joint position; importance of forward
weight shift to position the COM over the
BOS during sit-to-stand training or
biofeedback); best used to highlight
information not readily available from intrinsic
feedback and if linked to active
problem-solving

A

Concurrent Feedback

60
Q

Feedback is given after the movement

A

terminal Feedback

61
Q

Feedback is presented immediately after the

movement.

A

Immediate

Feedback

62
Q

Feedback given after a brief time delay allows
the learner a brief time for introspection and
self-assessment (e.g., a 3-second delay).
Feedback given after long delays is
contraindicated, especially if other
movements not related to the task occur in
between, degrading learning.

A

Delayed

Feedback

63
Q

Feedback given after a set number of trials
(e.g., after every 2nd trial or every 5th or
every 20th trial)

A

Summary

Feedback

64
Q

Feedback given first after every trial, then
less frequently on subsequent blocks of trials
(e.g., after every 1st trial progressing to every
3rd trial, then to every 5th trial)

A

Faded

Feedback

65
Q

Feedback given only when performance
deviates outside the boundaries of correct
performance; error range is predetermined
(e.g., top and bottom range of errors is
determined).

A

Bandwidth - KR feedback

66
Q

One source of feedback is provided; KR is
presented about the same segment on
consecutive trials; learner processes a limited
information about the task (e.g., during gait
training, KR is presented about knee segment
only on successive trials).
Blocked KR improves performance of the
identified segment but may not improve
performance and learning of the whole task
(multiple segments); performance
deteriorates once KR is withdrawn

A

Blocked

feedback

67
Q

Multiple sources of feedback are provided;
KR is presented about different segments on
successive trials (e.g., during gait training, KR
is presented about various different body
segments [trunk, hips, knees] on successive
trials). Random KR is superior in improving
both performance and learning of a task;
encourages learner to process a wider range
of information about the task

A

Variable
(random)
feedback

68
Q

Practice

➔ General principles of practice:

A

◆ (1) inc practice results in increased learning
◆ (2) large and rapid improvements in
performance are typically observed initially
with smaller improvements noted over time
➔ How should practice periods and rest periods be
spaced (distribution of practice)?
➔ What tasks and task variations should be practiced
(variability of practice)?
➔ How should tasks be sequenced (practice order)?
➔ How should the environment be structured (closed vs.
open)?
➔ What tasks should be practiced in a parts-to-whole
sequence?

69
Q

Massed Practice vs. Distribution Practice

a sequence of practice and rest
times in which the rest time is much less than the
practice time.

A

➔ Massed Practice -

◆ Massed practice can be considered when
motivation and skill levels are high and when
the patient has adequate endurance,
attention, and concentration
◆ disadvantage: Less time ung rest time -
increased fatigue sa part ng pt
◆ Pag mataas na yung level of movement

70
Q

Massed Practice vs. Distribution Practice

sequence of practice and rest
periods in which the practice time is often equal or
less than the time at rest.

A

➔ Distributed practice -

◆ Distributed practice is of benefit if motivation
is low or if the learner has a short attention
span, poor concentration, or motor planning
deficits
◆ Distributed practice should also be
considered if the task itself is complex, long,
or has a high energy cost
◆ for beginners

71
Q

Blocked Practice vs. Random Practice

practice sequence in which all of
the trials on one task are done together, uninterrupted
by practice on any of the other tasks

A

➔ Blocked Practice -

72
Q

Blocked Practice vs. Random Practice

practice sequence in which the
tasks being practiced are ordered randomly across
trials

A

➔ Random Practice -

73
Q

➔ Both allow motor skill acquisition pero sa random
practice, mas matagal yung retention ng skill, lalo na
pag iba iba yung order
➔ Kapag chinachallenge mo kasi ung utak sa huli, mas
naaalala niya yung certain movement

A

Blocked Practice vs. Random Practice

Q

ECOLOGICAL THEORY

Modification in PT intervention

A

◆ Application:

76
Q

➔ Refers to the sequence in which tasks are practiced

➔ In terms of retention, mas mataas na retention si
Serial order and si Random order

A

Practice Order

77
Q

Practice Order

refers to the repeated
practice of a task or group of tasks in order

A

◆ Blocked order -

● E.g. Task order → si task 1
gagawin mo in three trials → 1, 1, 1
● Task 2 three trials din and so on

78
Q

Practice Order

refers to a predictable and repeating order

A

◆ Serial order -

● Task order → 1, 2, 3 → then uulit
ulitin mo lang ulit like in three sets,
three times mo ginawa yung 1, 2, 3

79
Q

Practice Order

refers to a non repeating and unpredictable order

A

◆ Random order

● E.g. task order → starts c task 3, 1, 2 , then sa susunod naman is 2, 1, 3

80
Q

➔ A practice method in which performance on the task is
imagined or visualized without overt physical practice
➔ Consistently been found to facilitate the acquisition of motor skills
➔ Also effective in alleviating anxiety associated with
initial practice by previewing the upcoming movement
experience
➔ Mental practice, when combined with physical
practice, has been shown to increase the accuracy
and efficiency of movements at significantly faster
rates than physical practice alone.

A

Mental Practice

➔ Visualize muna ang training para nawawala anxiety
nung pt
➔ Smoothly mo siya naiisip kaya smoothly mo rin siya
magagawa

81
Q

➔ The component parts are practiced before practice of
the whole task is attempted
➔ It is important to identify the key steps through
accurate task analysis and to sequence them in the
required order
➔ Part-whole practice is most effective with discrete or
serial motor tasks that have highly independent parts
➔ Part-whole practice is not as effective for continuous
movement tasks or for complex tasks with highly
integrated parts

A

Part - Whole Practice

➔ Iniisa isa muna ituro per component then you do it as
a whole

82
Q

➔ Refers to the gain (or loss) in the capability of task
performance as a result of practice or experience on
some other task
➔ Lead Up Tasks - activities presented to prepare
learners for a more important or complex task or
activity

A

Transfer of Training

➔ E.g. sa exercise when introducing new exercise,
papagawa muna iyon sa unaffected side, then
papagawa ng 10 reps doon, magkakaroon na siya ng
