PNF techniques Flashcards
What is rhythmic initiation (RI)?
- start off passive
- progress to AAROM
- last to AROM through increments of range
What does rhythmic motion do?
inhibits arousal to achieve relaxation (inhibit RAS)
RI: speed of movement
- slow and maintained
- avoid quick stretches
RI: What ROM is used? Why?
- available range
- avoid protective response from pt
RI: which pts would this be a good technique for?
- pts who are unable to initiate movement due to increased tone
- pts with limited ROM from increased tone
*don’t want to increase spasticity and lose ROM
RI: useful while
teaching an activity
What is rhythmic rotation (RR)?
- pt relaxed
2. PT slowly and passively moves through ROM while rotating and derotating the part on its axis
purpose of RR
- slow rhythmic rotation inhibits RAS
- rotary movement relax and “unlock” the muscles
Which pts would benefit from RR?
- pts whose spasticity increases with AROM
- pts with spasticity and no AROM
What may need to be added to RR for pts who can’t relax?
traction
What is HRAM?
ISOMETRIC contraction in a SHORTENED RANGE of a pattern against graded resistance
HRAM procedure
- Hold is built up
- Pt given cue to relax
- When PT feels the relaxation, quickly move to lengthened range
Active phase of HRAM (procedure)
- apply quick stretch
- cue pt to actively return to shortened range
- PT can assist, track, or resist
What is the purpose of isometric hold in short range (HRAM)?
- increases muscle spindle sensitivity
- » during quick stretch in lengthened range, spindle d/c is maximized
Resistance during the active phase of HRAM stimulates _____
isotonics
Which pts would benefit from HRAM?
pts with weakness and/or unable to initiate movement from lengthened range
Where is hold relax (HR) performed?
at the point of limitation in ROM
HR procedure
- pt moves to point of limitation
- PT resists isometric contraction
- resistance build up to max tolerance and maintained
- pt cued to relax
HR: What happens when the PT feels the pt relax?
cued to actively move into the desired ROM
What is the basis for using HR?
- GTO firing inhibits range limiting pattern
- active movement into pattern results in reciprocal inhibition of range limiting pattern
Which pts would benefit from HR?
pts who have pain with mvt
Which joints are best suited for HR?
joints that don’t have a large rotary component
