Q

Proprioceptive

A
  1. Stimuli produced within an organism by movement of its tissues
  2. Sensory receptors which are stimulated by some aspect of muscle length, tension, joint angle, either stationary or moving, and by head position. Refers to all sensory receptors including exteroceptors and interceptors. (I.e. muscle spindles, G.T.O.s, joint connective tissue, skin receptors, eyes, ears, inner ear receptors)

Q

Facilitation

A
  1. The promotion or hastening of any nautral process, specifically the effect produced in nerve tissue by the passage of an impulse which lowers resistance to transmission so that a second stimuli or subsequent stimuli may more easily evoke a response.
  2. Increase ease of performance of any action, resulting from the lessening of nerve resistance by the continued successive application of the necessary stimulus.
  3. To make easier.
  4. Inhibition of abnormal tone and movement patterns are intricate components of facilitation.

Strength or Power

A

Proper contact to the segment being facilitated increases strength of contraction.
Proper placement should be either specific to
1. the surface which corresponds to the direction of movement (indirect) facilitation
2. Skin surface over the actual muscle of which a stronger contraction is desired (direct)

Q

Lumbrical Grip

A

Provides efficient facilitation while imparting a feeling of security. Utilizes the intrinsic muscles of the hand which decreases the potential for grabbing the patient or touching too many surfaces.
Contact surfaces: palm (thenar and hypothenar) and finger pads. Grip should be comfortable (Pain inhibits appropriate response)
Amount of contact depends on body part being resisted and size of patient.

Q

Therapist Body Mechanics

A

Therapists moves directly influence how pt moves. PT movements must mirror image of patient’s movement
Guidelines:
1. PT spine in neutral throughout with movement from legs, hips, and upper extremities
2. Weight shift/movement always in the direction desired of the pt
3. Weight shift/movement in direct proportion to pt movement
4. Movement of PT body is directly related to the arc of motion being performed by pt to ensure proper direction and strength of resistance throughout entire ROM
5. PT body position should always allow for the resistance to come from the therapists trunk, pelvis, and legs, not arms

Q

Maintained Isotonic

A

Concentric contraction with resistance by PT allows minimal to no motion to occur.
Facilitates appropriate strength, endurance, and irradiation.
Efficient MI initiates with appropriate core, immediately followed by the global response allowing for irradiation to the localized core muscle or other phasic or global groups.
PT attentive to motor recruitment pattern to ensure appropriate facilitation of temporal and spacial summation for irradiation.
*INTENSION OF THE PT IS MOVEMENT even when no movement is allowed, global muscles are facilitated with an efficient “CoreFirst” motor strategy.

COMMAND: “Keep it there” “Don’t let me move you”

Q

Isometric Contraction

A

Intension is a stabilizing contraction in which minimal or no joint motion occurs. Patient intention is to maintain a position in space against external resistance. Contraction is built and released slowly with PT constantly attempting to match the force being generated by the patient. Most closely resembles the true stabilization contraction observed during functional postures and activities.
MOST EFFECTIVE FOR FACILITATING AND TRAINING THE CORE MUSCLE CONTRACTIONS THROUGHOUT THE BODY. FACILITATES FIBER SPECIFIC RESPONSE

Low and slow resistance
Command: “Hold it, don’t let me move you. Don’t push”

  • give careful consideration to the overflow or irradiation which occurs during the course of the contraction; can give valuable input about the functional or structural integrity of the pts body.

UTILIZES temporal summation to increase the local response and slowly builds to facilitate an appropriate CoreFirst motor strategy. Irradiation is effective to facilitate a spreading of the controlled contraction.

25
Stretch reflex Definition
Spinal reflex used in conjunction with the techniques and procedures of PNF to facilitate a reflex contraction
26
Quick stretch technique
Stretch reflex is best facilitated through quick stretch by elongating a group of muscles in pattern to their lengthened or slightly taut range; applying traction and quickly/gently elongating the muscle further into the direction of pattern. *Spring test before applying stretch stimulus *reflex is synchronized with a verbal command to stimulate a volitional effort by pt *Reflex response is reinforced by the immediate application of appropriate resistance in the first few degrees (or no proper core response)
27
If tension is maintained, the stretch stimulus...
can be superimposed on an existing contraction -No recoil=cannot apply stretch stimulus. Begin with isometric to generate tension
28
Stretch reflex is used to achieve and enhance normal movement by:
1. Facilitating initiation of motion 2. increasing strength of muscle contraction 3. increasing endurance by decreasing muscle fatigue and decreasing effort needed to produce movement 4. influencing the direction of movement
29
Contraindications for quick stretch
1. hyperactive stretch reflex not under voluntary control 2. pain
30
Verbal commands should be
Simple Concise audible specific to the desired contraction
31
Verbal commands used to
- Coordinate volitional effort with reflex response - Define the type of muscular contraction desired - Define direction of motion - Signal timing of relaxation of contraction - Facilitate increased arousal and responsiveness - Stimulate generalized relaxation
32
Visual stimuli assists in
1. Initial learning of activities 2. Identifying direction of motion 3. Identifying position in space 4. Directing the motion of the head, trunk and extremities across midline and on the same side 5. Increasing ROM
33
Three components of PNF Upper Extremity
- Flexion or extension - Abduction or adduction - Rotation
34
Three components of PNF trunk/scapula-pelvis
- Flexion or extension/Elevation or depression - Lateral or medial movement - Rotation/upward or downward rotation
35
Patient position during PNF
influences the success of PNF principles Consider supports, influence of tone, comfort, and desired neuromuscular response
36
A. Normal coordinated activities are accomplished by the extremities and trunk moving in diagonal directions with spiral components B. Stretch reflex is most effectively elicited when the segment to be stretched is elongated in a specific diagonal C. muscular response is more coordinated and forceful when resistance is applied within a specific diagonal pattern D. 3 components E. Patterns are effective tools for evaluating the quality of muscular contraction and the range of motion. Specific techniques used to facilitate improvement with dysfunctions F. Patterns are narrow diagonals, identified by groups of muscles or segments in an elongated position with all muscles feel equally on stretch. Muscles work together in pattern with more power and efficiency G. Pattern is means to the end not end of the means
Patterns of facilitation
37
Timing: CoreFirst Motor Strategies
The sequencing of motor recruitment which takes place in a normal functional activity or movement. NEED TO RECOGNIZE THE NORMAL TIMING OF AN ACTIVITY AND ADJUST THE RESISTANCE AND/OR VERBAL COMMANDS TO FACILITATE THE REINFORCEMENT OR RELEARNING OF THIS TIMING.
38
Normal timing progression
Proximal stability - distal mobility Core stabilizers - prime movers
39
Normal timing allows for
Dynamic stability with controlled mobility
40
Most fundamental and critical principle in PNF
Positioning for success
41
Alignment has a direct influence on
Neuromuscular response - essential for appropriate motor control
42
Basic Philosophy of PNF
1. all human beings have untapped existing potential 2. Treatment purpose to assist the patient attain highest level of function possible through development of most efficient neuromuscular system
43
Developmental sequence
Series of posture and movements which facilitates the activation of necessary neuromuscular function and motor control necessary for efficient daily activities and function
44
A breakdown in the body's ability to effectively execute developmental postures and movements can be directly correlated...
To dysfunctions in an individual's daily, recreational, and work activities.
45
Why can developmental skills be learned or lost?
Never effectively learned Learned and lost due to injury or pathology
46
What are developmental skills
Ability to roll, assume postures such as on elbows and hook lying or sit and ambulate with proper CoreFirst
47
Goal of developmental foundations
Identify the missing Neuromuscular function or inefficient strategies and facilitate the function and control the developmental sequence is designed to obtain within our system
48
Things to assess and train for efficient function with developmental sequence
Assumption of position Stabilization within the position Movement within the position over fixed distal extremity or BOS
49
Building on the current knowledge of motor learning
Create functional learning environment Identify whole activity then identify specific parts to assess and treat for mechanical capacity and neuromusclar function Reintegration the restored functioning part to the motor control of the whole
50
Progression of treatment
1. Facilitate efficient NMN of interconnecting segment 2. Utilize the interconnecting segment to facilitate Corefirst trunk control 3. Utilize efficient trunk control and interconnecting segments to facilitate efficient extremity movement and function 4. Progression to weight bearing activities with corefirst strategies in all ADL
