44
Q

What is traction for PNF?

A

Distraction force applied to facilitate flexor muscles mobilizing patterns
-Elongation of an extremity
-Applied throughout the arc of motion and is used to facilitate muscle v

45
Q

What are the principles for PNF?

A

Patient position
Therapist position
Manual contacts
Verbal cues
Patterns of movements
Timing
Resistance
Approximation
Traction
Visual input
Irradiation and reinforcement
Quick Stretch

46
Q

What is Patient position for PNF?

A
  • As close to neutral alignment as possible and providing support to body segments as needed
  • Muscle position at optimal range allows for maximal contractile response
  • Changing the patient’s position can emphasize certain segments of a pattern and alter demands
47
Q

What is the midrange during PNF?

A

Greatest tension

48
Q

What is the shortened range during PNF?

A

Weak contractile forces

49
Q

What is the lengthened range during PNF?

A

Optimal stretch for the spindle

50
Q

What is irradiation and reinforcement of PNF?

A

-Overflow of neuronal excitation from stronger motor units to motor units that may be weaker or inhibited
-Spread of expansion of muscle response from stronger muscles to weaker muscles

51
Q

What is stretch for PNF?

A
  • Lengthened muscle and stretch reflex are used to initiate movements and to facilitate contractions
  • Verbal cues should be synchronized with the stretch to enhance movements
52
Q

What are the patterns of movement for PNF?

A

Normal functional synergistic patterns are facilitated

53
Q

What is the visual input for PNF?

A

Patient uses vison as a source of feedback to guide movements

54
Q

What are the different PNF techniques?

A
  1. Rhythmic initiation
  2. Combination of isotonics
  3. Stabilizing reversals
  4. Rhythmic stabilization
  5. Dynamic reversals
  6. Repeated quick stretch
  7. Contract relax
  8. Hold relax
55
Q

What is rhythmic initiation?

A

Used to promote learning of new movements, improve coordination, and promote relaxation and independent movement

56
Q

What are the 4 phases of movement for rhythmic initiation?

A
  1. Passive movement through the range
  2. Active assisted movement
  3. Independent movement
  4. Resisted movement
57
Q

What are the 2 types of reversals of antagonists?

A
  1. Dynamic reversals (isotonic reversals)
  2. Stabilizing reversals
58
Q

What are dynamic reversals (isotonic reversals)?

A

Use isotonic concentric contractions of agonists then antagonists performed against resistance

59
Q

What are stabilizing reversals?

A

Alternating contractions with minimal movement (slow reversals) progressing to smaller ranges and stabilizing holds of first agonists then antagonists

60
Q

What is rhythmic stabilization?

A

-Uses isotonic contraction of antagonist patterns with a focus on the contraction of muscles
-Start on one body part in one direction and another body part in the opposite direction

61
Q

What is repeated stretch?

A

-Repeated contractions
-Repeated isotonic contraction directed to the agonist muscles, inhibited by quick stretch and using resistance
-Can ve used in lengthened range for weaker muscles of just in the range that is weaker

62
Q

What is combination of isotonics?

A

-Uses concentric, isometric, and eccentric contraction of agonists muscles without loss of tension
-Limb is resisted moving through the range followed by stabilizing contraction (holding) and then an eccentric lengthening contraction, moving slowly back to starting position
-No relaxation between contraction

63
Q

What is timing for emphasis?

A

-Alters the normal timing of a pattern using resistance to enhance more localized contraction
-Allow irradiation to occur
-Used for weak or poor coordination

64
Q

What is contract relax?

A

-Stretching facilitation that is used at a limited point of ROM
-Therapist asks for a strong contraction in the range restricting (antagonist)
-Contraction is held for 5-8 seconds enhancing relaxation
-Voluntary relaxation and active movements then follows
-Works through reciprocal inhibition

65
Q

What is hold relax?

A

-Stretching facilitation performed in a position of comfort and below level of pain
-Patient actively moves the limb to the pain free end ROM
-A strong isometric contraction of the antagonist is resisted followed by relaxation and passive movement into the new range

66
Q

What is replication (hold-relax-active movement)?

A

-Stretching thechnique that is performed with the shortened range
-Isometric contraction is resisted followed by relaxation and passive movements to lengthened range then an isotonic contraction through the range into the end position again
-Goal is increasing ROM

67
Q

How does practice help with motor learning/skill?

A

-Has a major affect on motor learning
-Increased practice = increased motor learning
-Therapist should prepare the patient for practice with the desired movement and insure enough time.
-Avoid negative learning situations where the patient is learning improper habits and postures
-When choosing practice, the therapist must consider motivation, attention span, concentration,
endurance, and type of task.
-Mass vs distributed practice
-Blocked vs random practice
-Blocked order vs random order vs serial order
-Mental practice
-Part-whole
