PNF techniques Flashcards
1
Q
PNF principles: position
A
- therapist position is important for both techniques and patterns
- position yourself in line with the pt’s movements
- allows you to provide the best tactile feedback and resistance
- precise manual contacts on the working muscles helps
- guide and teach movements
- promote muscle contraction
2
Q
PNF principles: manual contacts
what to do/what it does
A
- precise manual contacts on the working muscles helps
- guide and teach movement
- promote muscle contraction and activation of synergists
- enhance kinesthetic awareness
3
Q
PNF principles: visual input
A
- encourage pt to watch movements helps with motor learning and motor control
- encourage pt to follow hand or arm movement with their eyes during UE patterns encourages incorporation of trunk and promotes functional movement
4
Q
PNF principles: resistance
A
resistance can improve
- kinesthetic awareness - using tracking (light resistance)
- improve strength: using more resistance to match pt’s abilities
- relax muscles: maximal resistance to promote autogenic inhibition and increase muscle length
5
Q
PNF principles: approximation
A
- approximation increases weight through weight-bearing structures
- encourages muscle contraction to maintain weight-bearing and uprigth position
6
Q
PNF principles: traction
A
- providing slight traction of the joint capsule can help facilitate muscle activity and movement
- note avoid using if patient has a subluxation of joint
7
Q
what do PNF techniques do?
A
- designed to facilitate the neuromuscular system
- promote/facilitate increased muscle activity using: tactile/kinesthetics/proprioceptive input
- some techniques used input to reduce muscle activity
8
Q
PNF techniques for mobility
A
- rhythmic initiation
- repeated contractions
- contract-relax
- hold-relax
- rhythmic rotation
9
Q
Rhythmic initiation
A
Used for early mobility:
- sidelying to supine/prone
- hooklying to sidelying
key principles:
- movements go from passive to active assisted to active
- move from a small range through progressively larger ROM
- using hands as proprioceptive feedback
- can be used when someone is trying to roll
10
Q
Repeated contractions
A
- tiny quick stretch to activiate muscle spindle
- used at a point of weakness to help promote muscle activity
- improves mobility by helping improve movement through ROM
- give muscle a series of short, quick stretches
- pressure will be in the opposite direction of patient movement
- provide a verbal cue with your quick stretch
11
Q
Contract-relax
A
- used to increase muscle length
- uses contraction of tight muscle and rotation to promote relaxation
- patient moves actively to point of tightness with limb in ER/IR
- contracts tight muscle including rotation, as therpaist provides maximal resistance
- patient actively moves into new range
12
Q
Hold-relax
A
- used to increase muscle length
- uses contraction of tight muscles to promote relaxation
- patient moves actively to point of tightness
- patient contracts tight muscle, as therapist provides maximal resistance
- therapist passively moves patient into new range
13
Q
Rhythmic rotation
A
- used to increase mobility due to increased muscle tone
- helpful to temporarily relax pt to allow them to participate in therapy eg: working on sitting, rolling, standing, reaching
- therapist gentle moves tight limb into IR and ER
- increase amount of rotation as pt relaxes
- move limb through range as pt relaxes
14
Q
PNF techniques for stability
A
- stabilizing reversals
- rhythmic stabilization
- prolonged holds
- replication
- used to increase stability in sitting, standing or stability through an extremity in weight bearing
15
Q
Stabilizing reversals
A
- therapist asks pt to resist contraction on one side of body, followed by resistance on other side of body
- pt reverses isometric contractions between sides of body
