Movement Science 2 (Exam 1-Midterm) Flashcards
1
Q
What is Motor Control?
A
Necessary input, sufficiently processed, with an acceptable output
2
Q
What is Motor Learning?
A
- Study of and acquisition (and reacquisition) and/or modification of skilled action
- Set of processes associated with the steps leading to relatively permanent changes in the capacity for producing a specific movement task
3
Q
What are the 3 stages of Motor Learning?
A
- Cognitive
- Associative
- Automous
4
Q
What is the difference between Intrinsic and Augmented (Extrinsic) feedback?
A
Intrinsic feedback includes: Visual, Auditory, Proprioceptive, Vestibular, and Tactile
Augmented feedback includes: Knowledge of performance and knowledge of results
5
Q
With Augmented Feedback, what does Knowledge of results (KR) mean?
A
- Terminal feedback about the movement outcome
- This is provided by an instructor or clinician
–Usually verbal
–Can be visual or auditory
6
Q
With Augmented Feedback, what does Knowledge of Performance (KP) mean?
A
- This is information about the pattern of a movement
–Kinematic feedback: speed, velocity, displacement
–Kinetic or EMG feedback if equipment: force and muscle activity
–Quality of movement: no reference to goal or outcome
7
Q
What is Concurrent Feedback?
A
Feedback given during task performance
8
Q
What is Constant Feedback?
A
Feedback given after every trial
9
Q
What is Delayed Feedback?
A
Feedback with a brief time delay
10
Q
What is Summary Feedback?
A
Feedback after a set number of trials
11
Q
What is Faded Feedback?
A
Feedback given less frequent with ongoing practice
12
Q
What is Terminal Feedback?
A
Feedback given at the end of task performance
13
Q
What is Bandwidth Feedback?
A
Feedback given if performance falls outside a predetermined error range
14
Q
How may feedback affect performance? How do you consider their stage of learning?
A
- Frequent extrinsic feedback may improve performance but slow learning
- Less extrinsic feedback may slow performance initially but may lead to improved learning (retention test)
- If the patient is in the cognitive stage of learning. they should get feedback more frequent to develop reference of correctness
- If the patient is in the associative and/of autonomous stage of learning they should get feedback less frequent
15
Q
What are General Practice Principles?
A
Practice attempts should be maximized to promote motor learning
16
Q
With practice, what should be the therapist role?
A
Therapist should ensure the patient practices correct movements to prevent negative learning
17
Q
In Practice Progression, What is Massed vs. Distributed progression?
A
Masses: has more practice time vs rest time
Distributed: has more rest time vs practice time
This depends on the patient, either can be chosen, however usually progressed TO massed in the autonomous stage
18
Q
In Practice Progression, What is the difference between Constant vs. Variable practice?
A
Constant: Task is practiced in the same way with no variety; This is better for performance
Variable: Task is practiced in variable conditions and parameters; This is better for learning
19
Q
In Practice Progression, What is the difference between Blocked vs. Random practice?
A
Blocked: 1 task repeated throughout whole practice time; This promotes performance
Random: A variety of task are practiced during practice time in random order; This promotes learning
20
Q
What is the difference between Discrete and Continuous, in terms of task constraints on movement control?
A
Discrete: Recognizable beginning and end
Continuous: Performer decides end
21
Q
What is the difference between Closed and Open, in terms of task constraints on movement control?
A
Closed: Fixed or predictable environment (Little variation of movement)
Open: Unpredictable; must adopt movement strategy (Constant changing of positions)
22
Q
What is the difference between Stability and Mobility, in terms of task constraints on movement control?
A
Stability: Nonmoving BOS
Mobility: Moving BOS
23
Q
What is the difference between Manipulation and Non-Manipulation?
A
Manipulation: Use of your hands to accomplish a goal
Non-Manipulation: No use of hands

31
With Functional Movement System (FMS) what are the different stages from the Fundamental Level to the Functional Level?
Fundamental Lvl:
1. Supine
2. Prone
3. Rolling
4. Quadruped
5. Crawling
Transitional Lvl:
6. Sitting
7. Kneeling
8. Squatting
Functional Lvl:
9. Vertical Stance
10. Gait
32
What is the 1st Principle for FMS?
We should move well, then move often.
- This is the "Natural Principle"
- Moving well enables us to adapt and gives us opportunities to develop and allows us to respond to environmental signals, it sets up the feedback that is vital for progressive movement; Moving often provides us with the ability to explore and expose ourselves to movement opportunities, this add volume across time and allows patterns and tissues to adapt
33
What is the 2nd Principle for FMS?
Direct us to protect, correct, and develop the movement of those in our care
- This is the "Ethical Principle"
- This can refer to the PT to address pain or avoiding patterns and exercises where pain and dysfunctions are present.
- Protection always precedes correction, which in turn precedes development
-- We must protect our clients from themselves and us by removing negatives that are reinforcing poor movement quality
34
What is the 3rd Principle for FMS?
Create systems that enforce the philosophy
- This is the "Practical Principle"
- Implementation of standard operating procedures, the practice of intelligent selection, always matching the risk to challenge ration to the growth and development desired
- If movement is below an acceptable standard for a movement vital sign or ability, thats dysfunction
- If some is unable to express physical capacity with a minimum standard of load, energy system response, frequency or volume, that deficiency
35
What is the Optimum Performance Pyramid?
This represents a type of athlete whose movement patterns, movement efficiency and sport skill are balanced and adequate
36
What is Over Powered Performance Pyramid?
This represents an athlete that generates power that exceeds their ability to move freely.
- This pyramid represents the individual who scores poorly on mobility and stability test but very high on power production
37
What is the Performance Pyramid? What do the rectangles represent?
This is a visual representation and understanding of human movement and movement patterns.
- The first rectangle lvl is the base platform or foundation. It represents that ability to move through fundamental patterns
- The second rectangle represents performance. This is general, measurable power or gross athleticism
- The third rectangle represents sport specific skill
38
What is the Under Powered Performance Pyramid?
This represents those athletes that have excellent freedom of movement but whose **efficiency is poor** and could stand improvement
39
What is the Under Skilled Performance Pyramid?
This represents those athletes who have overall weakness or **below-average performance**.
***A training program designed around sports skill fundaments and technique would be best investment of time for this person***
40
What are the 7 FMS exercises?
1. Deep Squat
2. Hurdle Step
3. Inline Lunge
4. Shoulder Mobility
5. Active Straight-Leg Raise
6. Trunk Stability Push-Up
7. Rotary Stability
41
Why should your patient/client do a Deep Squat Screen? What is the scoring for this screen?
This **shows whether the person can move symmetrically into a full ROM of the ankles, knee, and hips.** Maintaining the overhead position of the arms tells us if the individual can full access lower body mobility without robbing movement from the torso and UE.
- The scoring is a scale of 1-3, 3 being normal, and 1 being asymmetrical/not proper squat
Pain = 0
42
What does a 3 look like for the Deep Squat?
- The torso is parallel with Tibia or toward vertical
- Femur is below horizontal
- Knees do not track inside of feet
- Dowel aligned over feet
43
What does a 2 look like for the Deep Squat?
- Torso is parallel with Tibia or toward vertical
- Femur is below horizontal
- Knee do not track inside of feet
- Dowel aligned over feet
- Heels are elevated
44
What does a 1 look like for a deep squat?
- Tibia and Torso are not parallel
- Femur is not below horizontal
- Knees track inside of feet
- Dowel is not aligned over feet
*A score of 0 is given when pain is present*
45
With the Deep Squat Movement Pattern, why the symmetrical stance pattern?
The ability to squat is a fundamental movement ability. The deep squat is both a posture and pattern.
46
With the Hurdle Step Screen, why should the patient/client do the Double to Single Leg Pattern?
This is fundamental to our ability to walk and is the base of our locomotive mechanisms. **Its a display of control of our center of mass with a changing BOS**. Rolling, Crawling and other developmental milestones set the stage for this pattern
47
Why the Hurdle Step Screen?
This looks at single leg stance challenged by a dynamic stepping motion. The pattern demands a higher step then normal to express mobility and ROM with the stepping leg, while requiring stability of the stance leg
48
What is a 3 in the Hurdle Step?
- Hips, knees and ankle remain aligned in the sagittal plane
- Minimal to no movement in lumbar spine
- Dowel and hurdle remain parallel
49
What is a 2 in the Hurdle Step?
- Alignment is lost between hips, knees, and ankles
- Movement in lumbar spine
- Dowel and hurdle do no remain parallel
50
What is a 1 in the Hurdle Step?
- Inability to clear the cord during the hurdle step
- Loss of balance
*A score of 0 is given when pain is present*
51
With the Inline Lunge Movement Pattern, why the Spit Squat Stance?
This pattern requires us to lower our center of mass like we do with a squat but in a more dynamic way.
52
Why the Inline Lunge Screen?
This replicates the natural counterbalance the UE and LE use to complement each other, as **it uniquely demands spine stabilization. This test challenges hip, knee, ankle, and foot mobility and stability**, while at the same time challenging the flexibility of the Latissimus dorsi and Rectus femoris.
53
What is a 3 in the Inline Lunge?
- Dowel contact maintained
- Dowel remains vertical
- Minimal to no torso movement
- Dowel and feet remain in sagittal plane
- Knee touches the center of the board
- Front foot remains in start position
54
What is a 2 in the Inline Lunge?
- Dowel contact not maintained
- Dowel does not remain vertical
- Movement in torso
- Dowel and feet do not remain in sagittal plane
- Knee does not touch center of the board
- Flat front foot does not remain in start position
55
What is a 1 in the Inline Lunge?
- Loss of balance by stepping off the board
- Inability to complete movement pattern
- Inability to get into set up position
*A score of 0 is given when pain is present*
56
What is the purpose of the Ankle Clearing Screen? How is this documented?
To identify pain and to ensure ankle mobility is not a barrier to movement pattern competency and capacity
This screen is documented by using Green, Yellow, Red.
57
What is considered "Green" in the Ankle Clearing Screen?
- Knee moves beyond the medial malleolus of the front leg while the heel stays down
- This indicated the ankle has cleared mobility requirements
58
What is considered "Yellow" in the Ankle Clearing Screen?
- The knee resides within the width of the medial malleolus of the front leg while the heel stays down
- This indicates a potential ankle mobility limitation
- Failure on the ankle clearing screen implies that ankle mobility should be addressed and cleared
59
What is considered "Red" in the Ankle Clearing Screen?
- The individual's knee does reach the medial malleolus of the front leg while the heel stays down
- This indicates a potential ankle mobility limitation
- Failure on the ankle clearing screen implies that ankle mobility should be addressed and cleared
60
What is a 3 with the Shoulder Mobility Screen?
- Fist are within one hand length
61
What is a 2 with the Shoulder Mobility Screen?
- Fist are within one and a half hand lengths
62
What is a 1 with the Shoulder Mobility Screen?
- Fist are not within one and a half hand length
63
After the Shoulder Mobility Screen, what other test should you do, what is it for?
The shoulder clearing test is at the end of the Shoulder mobility test. If there is pain if this clearing test a 0 is given to the entire test.
- This clearing test is done bilaterally and it is necessary because shoulder impingement will sometimes go undetected by shoulder mobility test alone
64
Why the Active Straight-Leg Raise Screen?
Lumbo-Pelvic control, extension of the down leg and flexion of the raising leg are the components of this screen.
65
What is a 3 in the Active-Straight Leg Raise?
- Vertical line of the malleolus resides between mid-thigh and ASIS
- The non-moving limb remains in neutral position
66
What is a 2 in the Active-Straight Leg Raise?
- Vertical line of the malleolus resides between mid-thigh and joint line
- The non-moving limb remains in neutral position
67
What is a 1 in the Active-Straight Leg Raise?
- Vertical line of the malleolus resides below the joint line
- The non-moving limb remains in neutral position
*A score of 0 is given when pain is present*
68
Why the Trunk Stability Push-Up Screen?
This is not meant to test upper body strength in isolation. The goal is to use the upper body movement in this position to challenge the trunk stability pattern
69
What is a 3 in the Trunk Stability Push-Up Screen?
- Men perform a repetition with thumbs aligned with the top of the forehead
- Women perform a repetition with thumbs aligned with the chin
- The body lifts as a unit with no lag in the spine
70
What is a 2 in the Trunk Stability Push-up Screen?

71
What is a 1 in the Trunk Stability Push-Up Screen?
- Men are unable to perform a repetition with thumbs aligned with the chin
- Women are unable to perform a repetition with thumbs aligned with the clavicle
*A score of 0 is given when pain is present*
72
What test is done after the Trunk Stability Push-Up Screen?
- Extension Clearing Test, if there is pain give a (+) score with a final 0 score and perform a more thorough evaluation or refer out
73

- Fingers touch the lateral malleolus
- Knee and elbow achieve full extension
75
What is a 1 in the Rotary Stability Screen?
- Loss of balance
- Hand does not touch the lateral malleolus
- Knee and elbow do not fully extend
- Inability to get into set-up position
*A score of 0 is given when pain is present*
76
What test is done after the Rotary Stability Screen?
- The Flexion Clearing Test, Flexion can be cleared by first assuming quadruped position, then rocking back and touching the buttocks to the heels and chest to thighs. If (+) a final score of 0 is given
77
What is Functional Capacity Assessment/Evaluation?
A detailed examination and evaluation that objectively measures the patients current level of function, primarily within the context of the demands of competitive employment.
*Basically looking at the patients ability to do their job and the jobs impact on the patient*
78
What is Industrial Medicine (aka Occupational Medicine)?
The branch of medicine concerned with the maintenance of health and the prevention and treatment of diseases and accidental injuries in the workplace
79
Where did Industrial Medicine come from?
- Workers Compensation (WC) becomes a key issue:
--Early on, workers comp. was growing at same rate as medical cost
--Later on, workers comp. cost and claims increased
80
Why was Functional Capacity Evaluations introduced to Workers Comp.?
To help objectively measure a patients level of function within the text of the individuals work environment
81
With Industrial medicine, what are the steps an injured worker goes through to get back to work?
- After the work injury or work-related illness they are sent for treatment, either:
--Acute care (hospital; clinic)
--Rehabilitation (in/out patient)
- Then they go through a course of industrial medicine here they'll do:
--Evaluation (Job analysis {site/task} and functional assessment {Whole body})
--Treatment (Work hardening {rehab specific to work}, this resulted in formation of pain centers)
--Evaluation (Exit assessment (are they ready for RTW, then the do Special Programs)
*Special Programs (Made for prevention): Evaluation- pre-employment screenings and job analysis (site/task) and Education- Body mechanics and prevention of overuse syndrome*
82
Through the eyes of the employee, what are 2 perspectives that should be taken to account with their injury?
1) They want to be back to normal ASAP
2) Issue of secondary gain
- With workers comp. a person only receives a % of previous salary; "checks rarely come on time"
83
Through the eyes of the employee, what are some of the Financial considerations that should be taken into account with their injury?
- Firstly the patient is injured
- They are receiving less money
- Checks are not on time
- Their bills are still due
- Finances can cause increased stress in the household
84
Through the eyes of the employee, what are some of Household/Family considerations that should be taken into account with their injury?
- The person's identity changes due to changes in injury status:
--Staying at home
--No longer primary bread winner
--Can't pay bills
- There is pressure to get better; get a job
85
Through the eyes of the employer, what are some considerations that should be taken to account with the injured patient?
- 2nd most affected person
- Must pay the employee
- Must (re)train a replacement
- Must pay for (re)training...more cost
- Increased paperwork (claims)
- Concern ie. permanent disability
- Must make "reasonable accommodations"
86
Through the eyes of the employer, what are some Problems that should be taken to account pertaining to the injured patient? If a lawyer is involved what is there job in the situation?
- People will begin to point fingers at each other on how and why the worker got injured (Often employee blames unsafe work environment)
- No ground work for communication
- Increased likelihood for retaining a lawyer
The lawyers agenda is to win for their side
- PT/OT has good chance of being deposed
87
With a workers injury what is the role of the Physician?
- Utilizes the "medical model"
- Prescribe med, then ask them to return is a couple weeks
- Problem: MD communicates with employee/employer with medical terminology...not on their level...confusion
88
What is the role of the Rehabilitation Consultant? What should they consider?
- They are the interpreter from the medical community ...to work place, for the insurance company
- They are the patient advocates
- Determines # of visits, what MD to go to, and whether insurance will pay for a 2nd opinion
They should consider:
- Employee's perspective of rehab consultant
- Insurance companies dont make money, if they spend money
89
What is the role of the Government?
- They set the standards in the workplace
- They limit the amount an employee can sue medical professionals
- Implications for PTs, you need to carry malpractice insurance
90
What is the role of the Physical Therapist?
- Being good communicators and being professional towards the worker (employee), the employer, the lawyer, the rehab consultant and the doctor
- Being hands on with patients...establish rapport/trust
91
What does it mean to look at someone's Functional Capacity?
We must look at the persons ability to perform a job or the jobs impact on or requirement of the person
92
What are the results of the FCE used for?
- Information for rating disability
- Identify ways to modify the workplace
- Identify levels of "Return to Work"
- Identify symptom magnifiers
- Develop a rehabilitation plan
--Modify the worker - Work hardening
93
Specifically the Role of the FCE is to?
- Determine the presence/degree of disability
- Improve job role performance by identification of functional decrements
- Improve the likelihood of safe return to job/task performance
94
When doing a FCA, what are you supposed to look at?
- The abilities vs disabilities...what can a person do functionally
- At the whole body, not just parts
- Considers what is safe level of performance
- Must determine SAFE functional maximum
95
How do you determine a Safe Functional Maximum?
- They are not dictated by pain
- They may be safe and still have discomfort
- Do not stop test due to pain, if patient maintains proper body mechanics
- Test may be "self limited" due to pain
- SFM = @ least 100% max effort
- FCA : each station = max effort
96
What are the Physiological reasons to stop a test?
- HR, angina
- Skin color
- Sweating
- Muscle shaking
- SOB
- unsafe substitutions/compensations
97
What are potential outcomes of FCA?
- RTW
- Go to work hardening
- Disability
- Job modification
98
In order to complete a FCA, what is required?
- A large area
- Lots of time (4-6hrs, usually over 2 days), second day allows check for reliability...repeat test
- Trained PT/OT for consistency
--Follows a script (no encouragement/coaching)
--Professional judgement = Key...will patient be hurt
99
After the FCA/E, do you do a normal PT eval.?
Yes so you know physical limitations
100
What do FCA test look at?
- Strength
- May use 5 RM (For endurance and to reveal compensations with fatigue)
- May look at positions held for a given time
- Lifts may timed (At a particular pace)
- Coordination/balance
- Body mechanics
- Behavior during the test - pain is not a reason to stop test (if they stop, its a self limited test due to pain)
101
How does the FCA/E get further insight into consistency for the patient?
It uses test to "Simulate" the symptoms reconstruction (To test for faking)
102
What is the def. of Malingering?
Psychological diagnosis, therefore do not use
103
What is the def. of Symptom Magnification?
Describes objective inconsistency in the test
104
What is Symptom Magnification Syndrome (SMS)?
This stratifies symptom magnifying patients into personality types:
- Refugee
- Game Player
- Perpetual/Identified Patient
105
With Symptom Magnification Syndrome, what is the Refugee personality?
- Tends to be female with no future orientation
- If symptoms are maintained, they get out of resolved conflict
- Patients feel they are indispensible
- No career, rather job hop
- Martyr
- When asked, Can you do this...Patient response "yes but"
106
With Symptom Magnification Syndrome, what is the Game Player personality?
- Symptoms provide opportunity for a game
- Tend to be male, opportunistic
- They see symptoms as a way out of the slums
- Extravagant goal setting (beyond possible)
- Impulsive (they dont care about re-injury
- Tend to be irresponsible (But pretend to be responsible)
- Symptoms may be appropriate but rare
107
With Symptom Magnification Syndrome, what is the Perpetual/Identified Patient personality?
- Not gender specific
- They present with increased assistive device
- Likes patient role because it diminishes all other roles
- No real goal, rather survival
- Life is to be survived not enjoyed
- Tend to fall in the middle of the test for unknown reason
- Symptoms will/may be fictitious
108
How do we identify symptom magnifiers?
- Their symptoms are not controlled or effected by anything
- Their symptoms control activities; Activities no not control symptoms
- Things dont add up...Objective findings dont match the symptoms
109
The treatment of symptom magnifiers occurs with?
Work hardening
-Work hardening must have a psychological component to it...Behavior modification
- Work hardening is also used post FCA/E to address the impairments, functional limitations associated with that employees ability to do their job
110
What will work Hardening address?
It will address issues found in the FCA/E:
- Muscular Endurance
- Strength
- Attendance (Punch in/out)
- Increased ROM
- Cardiovascular Endurance
All in the context of work and job related requirements
- Clients becomes in control of documentation and progress
111
For industrial Medicine what would be the flow
FCE/A -> Work Hardening -> FCE/A (post, to determine if work hardening achieved our goals)
112
With the Guiding Principles of PNF, what are the components of Patient Position?
- Pt. should be in optimal alignment - Neutral
- Muscle position should be considered:
--Midrange: Greatest muscle tension
--Shortened Range: Weak contractile force
--Lengthened Range: Optimal stretch for muscle spindle
- Changes in body position can either increase of decrease the demands of a task
- Indications: Enhance muscle contraction and maximize postural stability
113
With the Guiding Principles of PNF, what are the components of Therapist Position?
Directly in line with the desired motion
- Use body to resist; this enhances therapist control of the patient, reduces fatigue, and protects against injury
114
With the Guiding Principles of PNF, what are the components of Manual Contacts?
- PT is guiding movement and providing resistance, and uses a lumbrical grip
- This enhances kinesthetic awareness (movement or position)
- It enhances muscle contraction and synergistic patterns
115
With the Guiding Principles of PNF, what are the components of Verbal Cues?
- Verbal cues should be clear, concise and well timed
- There should be Preparatory, Action, and Corrective verbal cues
- Verbal cues enhances the Pts. muscle contraction and synergistic movements
- Verbal cues improve motor learning
116
With the Guiding Principles of PNF, what are the components of Patterns of Movement?
- There are normal functional movements
&
- There are synergistic patterns
117
With the Guiding Principles of PNF, what are the components of Timing?
- Timing involves sequencing of muscle activity for smooth movement
- Proximal stability for distal mobility
- Normal timing in trunk is proximal to distal
- Normal timing in extremities is distal to proximal
118
With the Guiding Principles of PNF, what are the components of Appropriate Resistance?
- Optimal resistance facilitates muscle contraction
- Resistance applied is manually and functionally
- Types of contraction:
--Isotonic: Concentric/Eccentric
--Isometric
- PT should promote relaxation of antagonist muscle (Reciprocal inhibition)
119
With the Guiding Principles of PNF, what are the components of Approximation and Traction?
Approximation:
- Compression of joints
- Applied manually or functionally
- Ensure all joints are properly aligned
Traction:
- Elongation of joint
- Traction force is applied through arc of motion
- Facilitate muscle response
120
With the Guiding Principles of PNF, what are the components of Visual Input?
- Visual feedback
- This enhances and guides movement
(For example: using a mirror)
121
With the Guiding Principles of PNF, what are the components of Irradiation and Reinforcement?
- Irradiation: The spread of the response to stimulation, can either be:
--Facilitation (contraction)
--Inhibition (relaxation)
- Reinforcement: To strengthen; to make stronger
- The response will increase as the stimuli increases in either intensity or duration, this can occur in any direction and across any segment in the body
122
With the Guiding Principles of PNF, what are the components of Quick Stretch?
- This is used to facilitate muscle contractions and contractions of associated synergistic muscles
- The stretch reflex is elicited for muscles that are under tension from either elongation or contraction. To optimize the effects of the stretch reflex, all synergistic muscles in the pattern should be elongated
- Should only be used when your trying to facilitate a dynamic muscle activity
- Verbal cues must be synchronized with the stretch, for maximal benefit
- Can be contraindicated with injuries.
123
What is the overall goal for PNF techniques?
To promote functional movement through facilitation, inhibition, strengthening, and relaxation of muscle groups
124
What are different types of PNF techniques?
- Rhythmic initiation
- Reversal of Antagonists
(Dynamic reversal, and stabilizing reversals, Rhythmic stabilization)
- Repeated quick stretch
- Combination of isotonics (COI)
- Timing for emphasis
- Contract-relax
- Hold-relax
125
With PNF techniques, what is Rhythmic Initiation? Describe the different parts of the technique?
- This involved a rhythmic motion of the limb or body through the desired ROM, firstly start with PROM and progress to Active resistive movement.
Technique:
- PROM: "Relax, let me move you"
- AAROM: "Now, help me move you"
- AROM: "Now, move on your own"
- Resisted: "Now, push up"
126
What are the goals for Rhythmic Initiation (RI)?
- Promote learning of new movement and initiation
- Improve intra- and intermuscular coordination
- Promote relaxation, independent movement
127
With PNF Techniques, What is Reversal of Antagonists?
- This involves contraction of antagonist and is followed by an intensified excitation of the agonist
This includes 3 techniques:
- Dynamic Reversals
- Stabilizing Reversals
- Rhythmic Stabilizations
128
With Reversal of Antagonist, what is Dynamic Reversals Technique? What are verbal cues you can use? How can this benefit the patient?
- This involves the resistance of an agonist and then antagonist without pause or relaxation, during this the patient is actively moving the limb or body part through active ROM
- Cues such as "Push up" "Push down"
(Ex. if we are working with Bicep and triceps, I will actively resist you moving into flexion and then I will assist you moving into extension without pause or break)
Benefits:
- Helps improve intra- and Intermuscular coordination, strength, AROM, endurance, and to decrease muscle tone
129
With Reversals of Antagonist, what is Stabilizing Reversals? What is the muscle activity? What are the benefits?
- Alternating isometric contractions with stabilizing hold to agonist and then to antagonist opposed by enough resistance to prevent motion. **The intension is to move**
- The muscle activity from agonist to antagonist
Benefits:

204
What is Stability?
The resistance to a change in the body's acceleration or the resistance to a disturbance of the body's equilibrium
205
What are the 3 most important factors for achieving balance?
- A person has balance when the COG falls within the BOS (The upright posture is only stable when the line of gravity lies within the foot base)
- A person has balance in direct proportion to the size of the BOS (The larger the BOS, the more balance)
- A person has balance depending on mass (The greater the mass, the more balance)
206
What is Base of Support?
The supporting area underneath the body, it includes the points of contact with the supporting surface and the area between them
207
With BOS, what is High Stability (Low Mobility)?
This is characterized by a large BOS, a low COG, a centralized COG projection within the BOS, a large body mass, and a high friction at the ground surface
208
With BOS, what is Low Stability (High Mobility)?
This is characterized by a small BOS, a high COG, a COG projection near the edge of the BOS, a small body mass, and low friction
209
What is Center of Mass?
The unique point where the body's mass is equally distributed in all directions, may also be referred to as the center of gravity.
210
What are the 3 Balance Components?
- Vestibular
- Proprioceptive (Somatosensory)
- Visual
211
With balance what is Vestibular Input?
The ear has a labyrinthine structure that has balance receptors that detect movements of different types. There are receptors for head rotation, horizontal acceleration and vertical acceleration.
212
With balance what is Proprioceptive Input?
This is the sense through which we perceive the position or movement of our body.
- In order to perform balance skills a person must know their position in space, which is called Kinesthetic awareness, as well a possess quick reactions, coordination, agility, and flexibility
213
What is the Vestibulo-Ocular Reflex?
This is one of the fastest and most active reflexes in the human body. It uses head movements detected by the inner ear to generate compensatory eye movements that are equal - but in opposite direction - to head motions
- This ongoing adjustment of eye position results in a stable visual field, despite significant movement of the head
214
What type of balance is BOS?
Static: Fixed
Semi-Dynamic: Fixed
Dynamic: Moving
215
What type of balance is Surface?
Static: Stable
Semi-Dynamic: Unstable
Dynamic: Stable

--Slow
--Low Amplitude
- Contact surface is firm, wide and longer than foot
- Muscles recruited are distal to proximal
- Head movements in-phase with hips
217
What is Hip Strategy? When is this used?
- Used when perturbation is fast or large amplitude
- Surface is unstable or shorter than feet
- Muscles recruited are proximal to distal
- Head movement out-of-phase with hips
218
What is Stepping Strategy?
- This is used to prevent a fall
- Used when perturbations are fast or large amplitudes or when other strategies fail
- BOS moves to "catch up with" BOS
219
What factors affect balance?
- Posture
- Disease
- Meds
- De-conditioned state
- Disuse, injury, or surgery
- Fatigue
220
How does Posture affect balance?
- Posture affects balance, strength, and coordination
- Postural equilibrium is crucial to balance
221
How can injury/surgery affect balance?
- If there is a ligament injury, it may affect the joint proprioceptors and this will result in joint deafferentation (decreased input to afferent pathways), and this has a chance of reinjury
*Ankle is the most frequently injured*
222
How does deconditioning affect balance?
*Neuroplasticity*
- Use it or lose it
*If not actively practiced it will slowly go away*
223
How do you restore balance?
Balance is functional and is a skill
- To restore you have to work on integrated, coordinated, efficient, multidirectional movement and proprioception
224
How does Disease affect balance?
- May cause vision, sensation or neurological changes
225
How can fatigue affect balance?
- Muscular fatigue worsens or impairs joint position sense
- May also affect neuromuscular control of joint
226
How can CKC exercises help with balance?
What would happen if there is damage to the Mechanoreceptors?
*LEs function primarily in CKC*
Closed Kinetic Chain activities increase load to the joints stimulates mechanoreceptors and encourages functional muscle co-contraction
- Damage to mechanoreceptors will affect proprioception
227
Why is Proprioception and Balance Rehab. important?
- Proprioception is the center of performance and function
- Quick and coordinated muscle response helps to protect joint form injuries
- This works on static and dynamic (Kinesthesia) position sense
228
How do patients get balance back?
- Posture (Visual, Vestibular, and proprioceptive inputs)
- Core strength and stability (base strength before extremity strength, proximal stability before distal mobility)
- Stimulation of mechanoreceptors (weight bearing, oscillations, isometrics)
- Kinesthesia (Pertinent in orthopedic patients, pertinent in neurological patients)
- Strength and endurance (Isolate, functional, SAID, overload)
- Muscle balance (Length-tension relationship, force coupled)
- Neuromuscular system exercise (reflex, reaction time)
229
If a patient is doing a balance exercise, his balance will depend on...?
- Configuration of BOS
- COG alignment over the BOS
- Speed of postural movement
- Ability to maintain a position
- Ability to voluntary move
- Ability to react to perturbation

*70% of stabilization comes from this muscle*
The lumbar multifidus is the deepest posterior spinal muscle
- Unilaterally it would do trunk flexion, side bending and rotation of the opposite side
- Bilaterally it would extend the trunk and stabilize the vertebral column
*More of a tonic muscle*
248
How is the lumbar multifidus affected by LBP?
If you've had a hx of LBP, first time unilateral P!, these pt. had atrophy of the multifidus on the same side and the same segment as their acute unilateral LBP
249
What are the characteristics of the Transverse Abdominus?
This is the deepest abdominal muscle
- This muscle is in charge of compression, support and protection for the abdomen
- This muscle is recruited prior to any other muscle when there is expected and unexpected loading of the spine
250
How is the Transverse Abdominus affected by LBP?
- When it is no longer recruited first prior to loading of the spine
(Global muscle were activated first)
- This is going to result in a loss of stability to the spine and effect of the muscle itself
251
What are the characteristics of the Internal Oblique?
- The 2nd intermediate layer of the abdominals (Layer above transverse abdominus)
- If pelvis is fixed, the IO would flex and rotate to the same side, if the trunk is fixed then IO would side bend and rotate to the opposite side. Also compress, supports and protects abdomen
252
What is the definition of Neutral Spine?
The position in which an individual is most asymptomatic and the position in which an individual can produce the greatest amount of force through the extremities and the position in which an individual can best maintain balance and agility
253
When observing a pts. Neutral spine, how do we look at their alignment?
- Using a plumb line
- Palpation, of boney landmarks
- Vertical Compression
254
When assessing Neutral spine, how do you assess strength and balance?
- Force generation through the extremities
- The ability to maintain balance
255
When assessing Neutral spine, how do you assess Agility and Protective Mechanisms?
- This is the ability to receive proprioceptive feedback and response with change in direction
256
Once we have neural spine, how do we train the stabilization of muscles?
With co-contractions
257
When training the stabilization of muscles, what positions can you place the patient in? What are the 4 Ss?
- Prone
- Quadruped
*A good place to start because there is no external load, and they inhibit the Rectus abdominus*
- Supine/hook lying
*Progression to functional positions/postures; such as standing, squatting and sitting*
The 4 Ss:
- Supported Posture
- Suspended Posture
- Stacked Posture
- Standing Posture
258
When training for stabilization of muscles, how do you avoid substitutions?
- Isolate the muscle
- Avoid global muscle activation
- Inspect the pt.
- Palpate the muscle
- Use pressure biofeedback unit
- Use verbal and tactile cues
259
What are signs of dysfunction with the intrinsic stabilization subsystem?
- Abdominal Distension (abdomen expands)
- Change in LPHC alignment
--Excessive lordosis (APT)
--Excessive Forward Lean
--Asymmetrical Weight Shift
260
What muscles are part of the Intrinsic Stabilization subsystems?
- Multifidus
- Transverse Abdominus

261
What Muscles are part of the Anterior Oblique Subsystem?
- Adductors
- External Oblique
262

- TFL
- Adductors
266
What are the signs of dysfunction with the Lateral Subsystem?
- Frontal Plane Changes in Pelvis or Hip Alignment
--Genu Valgum
--Genu Varum
--Asymmetrical Weight Shift
267
What muscles are part of the Deep Longitudinal Subsystem?
- Bicep Femoris
- Tibialis Anterior
- Peroneus Longus
Also:
- Sacrotuberous Ligament
268
What type of muscle type are the muscles of stabilization?
Type 1 fibers, Slow twitch
269
How should you train the muscles of stabilization?
Endurance exercises
- Low load:Long durations
- Repeated bouts
270
When training the muscles of stabilizations, how should the patient progress going from NWB to Proprioception?
- NWB > WE
- Nonfunctional > Functional positions
- Simple movements > Complex
- No external Loads > External Loads
- Low Speed > High Speed
- Local Muscle > Global Muscles
- Proprioception
