|---|---|---|---|---|---|
| Definition of PNF | -Proprioceptive Neuromuscular Facilitation
-A therapeutic technique that utilizes concepts of normal development, biomechanics & proprioceptor function to maximize performance of motor skills
🗑
|

|

🗑
|
||||
| Types of input used in PNF | 1. touch

🗑
|
||||
| touch | tactile cue (a response between the touch and the skin/nerve endings)
🗑
|
||||
| stretch | provides stimulus to spindle to contract muscle
🗑
|
||||
| resistance | provides an overload that can stretch or increase tension of muscle fibers of joint surfaces; causes receptors in joint to react a certain way
🗑
|
||||
| traction | separation- response of contraction (flexors want to contract more)
🗑
|
||||
| approximation | compression (extensors want to contract more)
🗑
|
||||
| visual | using motor control center to establish eye/body part coordination and promotes muscle control
🗑
|
||||
| verbal | -we respond differently to different tones, volumes, speeds, etc
-use this to either relax a patient or tense up that patient depending on how much contraction the PT wants
🗑
|
||||
| Treatment Philosophy | -patient potential
-integrative
-positive approach
-functional
-strong assists weak
-maximal response
-repetition

|
||||
| Applications of Rhythmic Initiation | -unable to initiate movement
-limited active or passive ROM
-to teach an activity
🗑
|
||||
| Slow Reversal | an isotonic contraction of one pattern followed by an isotonic contraction of antagonist pattern (occurs once RI progresses to using resistance)
🗑
|
||||
| Applications of Slow Reversal | -to teach an activity
-muscle weakness which limits ability to initiate or complete a movement
-when there is muscle weakness in any compnent of an activity
-if someone is strong in shd muscles but weak in elbow and wrist muscles, promote strengthening

|
||||

-to increase strength when any component is weak
🗑
|
||||
| Alternating Isometrics | therapist resists an isometric contraction of one pattern and immediately follows with an isometric contraction of the opposite pattern. Resistance is built up within each shift and over the entire sequence (shorten range gradually until essentially zero)

||||
| Applications for Alternating Isometrics | -to balance tone
-pts who are unable to part/joint with RS
🗑
|
||||
| Rhythmic Stabilization | simultaneous isometric contractions (co-contraction) of antagonistic patterns. it is performed by therapist alternating antagonistic pattern resisted with each hand

||||
| Applications for Rhythmic Stabilization | -to develop stability in a posture, especially in the proximal joints of the extremities and in trunk, neck and head

|
||||
| Agonstic Reversal | -uses both concentric and eccentric

||||
