Indications for PNF
Increase strength, flexibility, ROM, endurance, stability, mobility, coordination of movement
Facilitate neuromuscular control
trunk patterns
D2 UE flexion = lifting pattern (D2 UE extension = reverse lift)
At end range, there’s facilitation of trunk extension, elongation of the opposite side of trunk, and weight shifting to the side the arm is lifted.
D1 UE extension = chopping pattern (D1 UE flexion = reverse chop)
At end range, there’s facilitation of trunk flexion, shortening of the trunk on the side of the arm is lowered, and weight shifting to the side the arm is lowered.
Contraindications for PNF
Early stages of soft tissue healing after injury or surgery
Acute or active arthritic conditions
Any movement that the doctor has deemed contraindicated or unsafe
Goals for PNF
Promote functional movement by facilitation, inhibition, strengthening, or relaxation of muscle groups
Outcomes of PNF
Establish head and trunk control
Initiate and sustain movement
Control shifts in center of gravity
Control the pelvis and truck in midline while the extremities move
Basic principles of PNF-refresher (10 essential components)
Manual contacts
Body position and body mechanics
Stretch
Manual resistance
Irradiation (overflow)
Joint facilitation
Timing of movement
Patterns of movement
Visual cues
Verbal input
UE Patterns of PNF-refresher
UE D1 flexion (feeding pattern)- Shoulder flexion/adduction/external rotation
UE D1 extension- Shoulder extension/abduction/internal rotation
UE D2 flexion (cheerleader hooray pattern)- Shoulder flexion/abduction/external rotation
UE D2 extension- Shoulder extension/adduction/internal rotation
LE patterns of PNF-refresher
D1 flexion (putting on a shoe)- Hip flexion/adduction/external rotation
D1 extension- Hip extension/abduction/internal rotation
D2 flexion (fire hydrant)- Hip flexion/abduction/internal rotation
D2 extension- Hip extension/adduction/external rotation
Challenging positions while doing extremity patterns
Quadruped position
Sitting
Standing
Scapular and Pelvic patterns
Done best in the side-lying position
These patterns assist with functional movements like rolling, reciprocal movements of UE/LE, scooting, and gait
Scapular patterns help with UE function, cervical and thoracic spine alignment
Pelvic patterns help with LE function and lumbar spine alignment
Scapular patterns
D1 flexion/extension: anterior elevation and protracted (shoulder shrug) - start at the 1:00 position move into the 7:00 position of posterior depression and retracted (hey, big boy)
D2 flexion/extension: posterior elevation-scapula is elevated and retracted (look at my pects) – start at the 11:00 position and move into the 5:00 position of scapula is anterior depression and protracted (putting something in your front pocket)
Pelvic pattern
D1 flexion/extension: start at the 1:00 position move into the 7:00 position of posterior depression (“sit back into my hands”)
D2 flexion/extension: really isn’t done but would be 11:00 to 5:00 movement
Trunk pattern is the
Foundation of controlled movement
Upper trunk patterns-consists of synchronous UE PNF patterns using both UEs
Promotes trunk musculature activation especially rotators and increases the overflow response in the trunk
Lead arm determines the specific name of the trunk pattern and is the hand that is free to move (the arm that is not holding the other arm)
PNF techniques
Multiple techniques to use depending on what the goal is
Example: isometrics to increase stability, isotonic movements to increase ROM and function
Techniques can be divided into the primary focus that technique has on motor control stages (mobility, stability, controlled mobility, and skill)
Rhythmic initiation ( improves mobility)
Sequential application of first passive, then active assisted, then active or slightly resisted motion
Good to use as a teaching tool
Rhythmic rotation ( improves mobility)
To promote tone reduction and relaxation
Application of slow rotary movements about a longitudinal axis
Hold relax ( improves mobility)
Purpose is to increase passive joint mobility and decrease movement-related pain
The limb is moved into the limit of the pain-free range
Isometric resistance is applied to the antagonist muscle or the agonist
The body segment is moved to the new range of motion
Hold relax active movement ( improves mobility)
Only one direction
Isometric resistance is applied to facilitate the agonist muscle in the shortened range
Then the limb is passively moved into a point in the lengthened position
Patient actively or with resistance pulls up into the beginning position
Repeat until there is no more gain in ROM
Contract relax (inc mob)
Effective when addressing decreased length in two-joint muscles and when pain is not a significant factor
Used to increase passive range and soft tissue length
Patient or therapist moves body part to the end of the available range then says “turn and push”. Therapist resists an isotonic concentric contraction to the rotational component while doing isometric contraction of the other shortened mm followed by relaxation then active movement into the new range
Alternating isometrics ( improves stability)
Isometric contractions of both agonist and antagonist muscle groups are facilitated in an alternating manner
Smooth transitions
Rhythmic stabilization ( improves stability)
Co-contraction of muscles surrounding the target joint using a rotatory force
Promotes stability and balance, decreases pain upon movement, and increases range of motion (ROM) and strength
Slow reversal (controlled mobility, and skill)
Concentric contraction of muscles in an agonist pattern is facilitated through manual contacts and verbal cues
Fatigue is minimized by rhythmically alternating between agonist and antagonist muscle groups
Slow reversal hold ( improves controlled mobility, skill, and stability)
Concentric contraction of muscles in an agonist pattern is facilitated through manual contacts and verbal cues
A resisted isometric contraction is held at the completion of range in each direction of the chosen pattern
Appropriate for use with single extremity or trunk patterns as well as functional movements
Agonistic reversals ( improves controlled mobility and skill)
To facilitate functional movement throughout a pattern or task
The agonist muscle groups are targeted both concentrically and eccentrically
Resisted progression (inc skill)
Focuses on the task of locomotion
Resistance is applied during functional activities
This technique may be applied during crawling, creeping, or walking
