  1. purpose of PNF
    • usually to facilitate movements, sometimes to inhibit (stretch, relax)
    • increase efficiency in neuromuscular system / increase efficiency of a movement in functional patterns
    • give feedback to neuromuscular system thru proprioceptive system
    • goal: smooth and coordinated movement with NORMAL POSTURAL CONTROL
  2. proprioceptors - basic def, and basics of where they're found
    • neurons that give brain info about body's position in space
    • found in joints, muscles (GTOs), vestibular system, vision
  3. philosophy of PNF
    • integrated approach suing sensory, musculoskeletal, and psych elements (say "I know you have potential!)
    • keen observation (visual and manual) by therapists precedes problem-solving
    • goals - function-oriented and realistic but optimistic, set by the PT and pt
    • treatments are goal-specific
    • facilitate whole skill learning via a learning sequence
    • work parts in isolation, then as a whole
    • repetition!
    • reciprocation (what the contralat limb and res of body are doing)
    • follow principles of motor learning
    • active role of pt and PT (knowledge of performance and results)
    • address posture and movement (orthopedics, neuromuscular, cardiopulm)
  4. about the goals in PNF
    • well defined,
    • reachable,
    • chosen with PT and pt involvement,
    • function-oriented,
    • so treatments are goal-specific
  5. inthe PNF philosophy, what's meant by "active role of pt and PT?"
    • knowledge of performance and results
    • and also team work in setting goals
  6. in PNF phil, 3 areas to look at regarding posture and movement
    • orthopedics
    • neuromuscular
    • cardiopulmonary
  7. irradiation
    overflow from one muscle: contract one muscle against resistance, and one or more nearby muscles, prox or distal, might get some contraction too
  8. successive induction
    contraction of antagonist followed by intensified excitation of the agonist -- this is the foundation for reversal techniques
  9. reciprocal innervation/inhibition
    • as antag contracts, agonist relaxes
    • (this is simultaneous, while successive induction is in sequence)
  10. maintained isotonic contraction
    a concentric contraction in which resistance applied by therapists allows minimal or no motion to occur to facilitate appropriate strength, endurance and irradiation
  11. 9 basic techniques (you need to memorize these)
    • body position and body mechanics (for pt and PT)
    • manual contacts
    • appropriate resistance
    • verbal commands
    • stretch
    • traction or approximation
    • vision
    • timing
    • pattern
  12. 3 phases of rhythmic initiation technique
    • passive
    • active assisted
    • appropriate resistance (not overpowering. geared to pt)
  13. purpose of rhythmic initiation
    • evaluate arc of motion and pt's ability to complete the arc
    • give pt a sense of the movement
    • relax the pt
    • muscle re-education (successive induction)

    use tone (sing-song voice) to help relax the pt
  14. the rhythmic initiation technique we did on day one
    pt sidelying, hips and knees at 90 degrees, pillow under head, pillow btwn knees, something under waist so there's not too much curve on top

    find the ASIS, now go above it to crest of pelvis, hands lumbrical, hook there and pull down at a slight angle, then push up on the ischial tuberosity

    pt's waist should expand and contract like a slinky
