A
Overflow (irradiation): Spread of a muscle response from stronger to weaker muscles. Primarily achieved through applying resistance.
Manual contact: stimulates the muscle to reinforce the movement AND guide the direction of the movement.
Therapist position: Needs to be directly in line with the desired motion and should be facing the direction of the desired movement.
Approximation: May facilitate increased stability, may be applied either manually or facilitated by gravity in upright, weight bearing positions.
Traction: Applied manually during PNF patterns to facilitate muscle contraction.

51
Explain fast/quick stretch?
- Provide a quick stretch of the agonist when changing directions
- Produces a relatively short-lived contraction of the agonist's muscle and short-lived inhibition of the antagonist muscle which facilitates a muscle contraction (muscle spindle)
52
Explain repeated contraction/stretch?
Move through a pattern pausing and applying a quick stretch, press through more motion, pause, quick stretch, push. Emphasizes strengthening in specific ranges throughout the motion
53
Explain dynamic (slow) reversal hold?

54
Explain agonist reversals?
Reversing the type of contraction you are eliciting from your patient, working concentrically, isometrically, and eccentrically
