Week 6 - PNF Flashcards
What is the goal of PNF technique?
To promote functional movement through facilitation, inhibition, strengthening and relaxation of muscle groups
What is the clinician’s body position when performing PNF?
Mirroring patient’s direction of movement for effective facilitation. In line with the movement where possible
Why use the lumbrical grip?
It stimulates the skin receptors
Golgi Tendon Organ (GTO)
Inhibits muscle contraction when it is activated by lengthening, especially if lengthening is slow
Greatest amount of resistance that can be applied to isotonic contraction and still allow full range movement to occur if working on mobility
Manual resistance
Upper Limb PNF Pattern - D1 Flexion
“Grab baton stick & stick it in ear)
- Shoulder flexion, adduction, ER
- Elbow partial flexion
- Forearm supination
- Wrist and finger flexion
Brushing hair
Upper Limb PNF Pattern - D1 Extension
“Grab your earring and throw it on the ground”
- Shoulder extension, abduction, IR
- Elbow extension
- Forearm pronation
- Wrist and finger extension
Closing car door
Upper Limb PNF Pattern - D2 Flexion
“Grab sword and throw it in the air”
- Shoulder flexion, abduction, ER
- Elbow extension
- Forearm supination
- Wrist and finger extension
Zipping side of pants
Upper Limb PNF Pattern - D2 Extension
“Catch the sword and put it in the sheath”
- Shoulder extension, adduction, IR
- Elbow extension
- Forearm pronation
- Wrist and finger flexion
Putting somewhere on shelf
Lower Limb PNF Pattern - D1 Flexion
“I trod on something, what is it”
- Hip flexion, adduction, ER
- Knee flexion
- Ankle DF and inversion
- Toe extension
Take off shoe
Lower Limb PNF Pattern - D1 Extension
“Oh it’s not poo, I’ll put my foot back down (and out)”
- Hip extension, abduction, IR
- Knee extension
- Ankle PF and eversion
- Toe flexion
Not used as frequent
Lower Limb PNF Pattern - D2 Flexion
“I need to pee, I can only pee like dog”
- Hip flexion, abduction, IR
- Knee flexion
- Ankle DF and eversion
- Toe extension
Lower Limb PNF Pattern - D2 Extension
Come back behind from D2 flexion
- Hip extension, adduction, ER
- Knee extension
- Ankle PF and inversion
- Toe flexion
Rhythmic initiation
Teaches patient how to initiate movement
Start with passive movement, move to active, then light resistance
3 types of repeated contractions
- Hold-relax active
- Hold-relax
- Contract-relax
What is hold-relax active?
Contract isometrically in lengthened position, then relax, and joint is actively moved by patient to the new position (facilitates antagonist)
What is the hold-relax technique?
Contract isometrically in lengthened position, then relax, and joint is passively moved by physio to the new position (inhibits antagnoist)
What is the contract-relax technique?
Same as hold relax but patient is allowed to perform the rotation component of the movement concentrically during the isometric contraction
Alternating isometrics
- Promotes stability
- Patient holds position and therapists ask for isometric contractions altering antagonists and agonists
“don’t let me push”
Rhythmic stabilisation
- Promotes stability
- Patient holds position and therapist applies multidirectional resistance
Slow reveresal
Concentric contractions of muscle groups, alternating agonist with antagonist
The Bobath concept seeks to…
- Optimise functional independence by encouraging the most efficient motor behaviour available to the individual
- Minimise compensatory motor behaviour of the less affected body segments/limb
- Minimise atypical motor behaviour of the more affected body segments/limbs
