What are the functional principles of PNF
- qualitative analysis of normal movement patterns
- integrative approach: memory, musculoskeletal, and physiological
- Keen observation by therapist proceeds problem solving
- set well defined goals and have the intention to reach them, involve the patient
- Goals are function oriented and treatments are goal specific
- facilitate whole skill learning via a learning sequence
- work parts in isolation and as part of a whole skill
- follow the principles of motor learning
- active role of patient and therapist
- address posture and movement

IN PNF WE USE LEARNING SEQUENCE
Define learning sequence
we can jump into any part we want in the developmental sequence
T/F
PNF works in isolation
PNF works in isolation and as part of a whole skill—incorporate a functional task
need repition to promote motor memory–to self correct
need reciprocation for function
PNF works in isolation and as part of a whole skill—incorporate a functional task
what two things does it need?
need reptition to promote motor memory–to self correct
need reciprocation for function
Why does PNF need repetition?
to promote motor memory–to self correct
Why does PNF need need reciprocation?
need reciprocation for function
How does PNF follow the principles of motor learning?
feedback
knowledge of performance, tone of voice–relaxed vs recruit motor units
Who is active in PNF?
active role of patient and therapist
patient will need to be able to follow command
knowledge of performance and results
Does PNF address posture and movement?
we always address the best possible posture
ortho, neuromuscular, cardiopulm
Irradiation—
overflow: motor unit recruitment, in response to effort already occurring
a spreading and increased strength of a response that occurs when either the NUMBER OF STIMULI or the STRENGTH of the stimuli is increased.
The response may be either excitation or inhibition.
What causes irradiation
a spreading and increased strength of a response that occurs when increase
- NUMBER OF STIMULI
- STRENGTH
The response may be either excitation or inhibition.
What is response of irradiation
The response may be either excitation or inhibition.
Successive Induction:
If have a muscle contracting, using the opposite will have facilitation due to that prior contraction
an increased excitation of the agonist muscle follows stimulation (contraction) of their antagonist.
Techniques involving reversals of agonists make use of this property (induction: stimulation, increased excitability.)
anterior elevation of scapula will help me make a better posterior depression
In successive Induction how do we facilitate a muscle contraction?
If have a muscle contracting, using the opposite will have facilitation due to that prior contraction
stimulation (contraction) of antagonist to facilitate increased excitation of the agonist muscle
Scapula example of sucsessive induction:
anterior elevation of scapula will help me make a better posterior depression
Reciprocal Innervation/Inhibition:
when agonist contracts the antagonist has to relax
contraction of muscles is accompanied by simultaneous inhibition of their antagonists. Reciprocal innervation is a necessary part of coordinated motion.
Relaxation techniques make use of this property.
In Parkinson’s, have them flex elbow, it is difficult because of high tone in biceps and triceps, we want to help with rhythm of movement to help relax overall tone to get the biceps to contract and triceps to relax
Types of Muscle Contractions
- Isotonic
Concentric:
Eccentric:
Maintained isotonic: blocked isotonic, patient does directional movement and therapist resists—pt intention is to be moving - Isometric: no movement, intention is to hold
- Tell patient to match my resistance
Concentric contraction
shortening , origin and insertion get closer (pull, push)
Eccentric
Eccentric: lengthening, origin and insertion get further apart (lower)
Maintained isotonic
Maintained isotonic: blocked isotonic, patient does directional movement and therapist resists—pt intention is to be moving
the intent of the patient is motion, the motion is prevented by an outside force, usually by resistance
Isometric
Isometric: no movement, intention is to hold
–Tell patient to match my resistance
Graph isometric:
gradually build force and gradually let off the force—command is “hold”, we are not looking for movement [rhythmic stabilization, hold relax, contract relax, slow reversal hold relax]
Graph maintained isotonic
: maintain the resistance, they feel like they are trying to go in a certain direction, and we aren’t allowing it “keep pushing, keep pulling, keep going” [basic technique of timing for emphasis] [special technique combination of isotonic: use concentric, eccentric and maintained isotonic: combination of isotonic, contract relax, slow reversal hold relax]
What are the 9 basic techniques?
- body position and body mechanics
- manual contacts
- appropriate resistance
- verbal commands
- stretch
- traction or approximation
- vision
- timing
- pattern
Body position and body mechanics:
BASIC TECHNIQUE
the position and body mechanics of therapist and patient
PT proper body positioning an mechanics to provide specific/well-aimed guidance for better control motion, movement, or stability
Manual Contacts
BASIC TECHNIQUE
used to increase power and guide motion or movement with proper grip and pressure
- Using lumbrical grip
- TELLS THE PATIENT WHERE TO GO
Appropriate resistance:
BASIC TECHNIQUE
appropriate to the task (NOT maximal)
- –Appropriate to patient and appropriate to task
- –Endurance: light resistance, strength: heavy resistance
—ie to do strength building, do a task to train the muscle and add more and more weight with less reps 70% of 1 rep max 5 reps, if building endurance lower resistance so more reps
Verbal commands:
BASIC TECHNIQUE
use of words and the appropriate vocal volume to direct the patient
light and easy vs strong and forceful
only use key words, minimal words ie. Hold, push
Stretch
BASIC TECHNIQUE
BASIC TECHNIQUE
the use of muscle elongation and the stretch reflex to facilitate contraction and decrease muscle fatigue
quick stretch on a tendon for a spinal cord reflex for a quick response, help initiate a movement, redirect a movement, and sustain a movement.
Stretch must be accompanied by a verbal command—pull into my hand, pull into my hand—needs to be times with a specific verbal command and needs to be followed by a resistance right after the stretch
Tapping into monosynaptic stretch reflex, resistance immediately after the stretch to tap into the alpha motor neuron system—muscle proprioceptive level for alpha motor neuron for the fibers to respond to stretch and for the contraction of the muscle
Initiate movement, redirect movement, help patient get to end of range
STRETCH: how do we apply it with verbal command and resistance
Stretch must be accompanied by a verbal command
—pull into my hand, pull into my hand—needs to be timed with a specific verbal command and needs to be followed by a resistance right after the stretch
Why do we apply resistance after the stretch basic technique?
Tapping into monosynaptic stretch reflex, resistance immediately after the stretch to tap into the alpha motor neuron system—muscle proprioceptive level for alpha motor neuron for the fibers to respond to stretch and for the contraction of the muscle
Purpose of stretch basic techniques (3)
- Initiate movement
- redirect movement
- help patient get to end of range
Traction or approximation:
BASIC TECHNIQUE
the elongation or compression of the limbs and trunk to facilitate motion and stability
adding distraction as taking limb through the arc of motion (resisting)-traction (during movement/special technique) increase mobility
stability, set muscle up for isometric contraction-approximation (precede movement/special technique)
Traction purpose
adding distraction as taking limb through the arc of motion (resisting)-traction (during movement/special technique) increase mobility
Approximation purpose
- stability
2. set muscle up for isometric contraction-approximation (precede movement/special technique)
Vision
BASIC TECHNIQUE
BASIC TECHNIQUE
Use of vision for the movement—vision added to the motion enhances the task—ie adding in a weight shift, incorporate trunk, can use a focal point,
use of vision to guide motion and increase force. Visual feedback simplifies motion. This is because patient tracks and controls movement and position with his eyes. By having eye contact the therapist and patient receive feedback about the performed movement.

Timing
BASIC TECHNIQUE
Normal timing–in adults normal timing of most coordinated and efficient motions is from DISTAL to PROXIMAL
Timing for emphasis –blocking one part of pattern to get irradiation to facilitate another part of the pattern (can block proximal to get distal or the opposite)
Maintained isotonic is used in timing for emphasis
–In the middle of a contraction motion with resistance and then resist a different component strongly to maintain isotonic, quick stretch with resistance at the same time as the maintained isotonic at another segment: ie blocking movement at ankle with quick stretch to hip to get hip to recruit (irradiation overflow of strong component to weaker component by maintained isotonic and at the same time try to facilitate weaker component)
promote normal timing and increase muscle contraction with proper inputs and through timing for emphasis
