| Define stretch. | Used to initiate voluntary mvmt and enhance speed of response at beginning of pattern | |
| Define quick stretch. | Facilitates mvmt in the opposite direction | |
| Describe repeated contractions. | Combinations of isometric and isotonic contractions, repetition causes learning, voluntary mvmt facilitated with stretch and resistance to strengthen for muscle re-ed | |
| Describe *Rhythmic initiation (on practical). | Used to improve the ability to initiate mvmt (parkinson's/apraxia), voluntary relaxation, passive mvmt, repeated isotonic contractions of agonist pattern, command | |
| Describe Reversal of Agonist Techniques. | Agonist is facilitated through resistance to antagonist,contraindicated in increased tone | |
| Describe Slow reversal. | Isotonic contraction of the antagonist (against resistance) followed by isotonic contraction of the agonist (against resistance) | |
| Define Rhythmic stabilization. | Alternating isometric contractions opposed by enough resistance to prevent motion, increases stability, balance, and strength | |
| What are Relaxation Techniques use for? | To increase ROM in presence of pain or spasticity | |
| Describe Contract-relax. | Passive mvmt to point of limitation, isotonic contraction of antagonist against max resistance (6-10 sec contraction) followed by relaxation then PROM | |
| Describe Hold-relax. | Used when there is pain, isometric contraction (no mvmt) of antagonist, relaxation, active mvmt of agonist | |
| Describe Rhythmic rotation. | Good when preparing for splint fabrication, decreases spasticity and increases ROM, PROM in desired pattern, when tightness if felt, therapist rotates the body part slowly and rhythmically (like in Rood approach) |
