Exam 3 - PNF Flashcards
Manual Contacts - tactile stim
- motor responses influenced by stim of skin receptors
- use a lumbrical grip
- motor response enhanced by proper contact
- give security
Traction - joint receptors
- manual distraction of joint
- promotes movement
- mm in lengthened range are on stretch and respond with more force
- helps dec pain
Contraindication for traction
inc pain
ligamentous injury
unstable joint
Approximation
- manual compression of joint
- promotes stability
- wt bearing, pushing, CKC activities
Contraindications of approximation
- increased pain
- fracture
- joint replacements
- inflammatory conditions
Appropriate facilitation
- amount of resistance that demands max effort from pt while maintaining the intention of the exercise
- Isotonic = for movement
- isometric = for stability
- for muscle re-ed
Irradiation/overflow
- Strong muscle contraction results in spread of stim to synergistic mm groups and movement patterns
- goal directed
- for facilitation or inhibition
- for specific groups or movement patterns
Contraindications for irradiation/overflow
increase pain fracture valsalva tendon surgery muscle flaps anywhere resistance is not appropriate
Stretch reflex
- manual fire muscle spindles to initiate and/or enhance muscle response. **Must be followed up with some form of resistance/facilitation or inhibition will occur
- Elicits contraction in paralyzed muscle **
- initiate voluntary movement
Contraindications for stretch reflex
- joint instability
- fracture
- pain
- creating dominant reflexes
- improper technique
Normal timing
- sequence of muscle contractions for coordinated movements (prox develops before distal, but movement is distal to prox for adults)
- normal timing may be goal of therapy
Why use patterns of movements?
- muscles respond more powerfully in specific diagonal patterns
Rhythmic initiation
- uni-directional technique
- used to teach motion (PROM»AROM)
- used to enhance initiation, promote motor learning and relaxation
- therapist sets rhythm
**Used to treat dysfunction of speed, direction, and/or quality (i.e., parkinson’s pts)
Rhythmic stabilization vs Alternating isometrics
Rhythmic = in multiple planes Alternating = through straight planes
BOTH = biometric techniques used for stabilization of an unstable joint. Can be used to inc ROM. Relaxing
Command to pt = “Hold”
Slow Reversals
Reversals of antagonist, isotonic reversals
- concentric/concentric
- utilizes reversing directions of smooth coordinated concentric contractions without relaxation btw reversals. Can use stretch reflex prn
-used to promote inc ROM, strength, coordination and power
