4.19 Eyes, Rood's Flashcards
What happens if there’s a lesion in the optic chiasm?
- lose nasal on both sides
- get a blind spot in the middle (opposite to horse blinders)
Homonymous hemianopsia is common in this type of stroke. What happens?
- left CVA
- right sided blindness
Important things for a pt who has homonymous hemianopsia to understand
- they will have to turn their head to read everything
- affects both near and far distance
pts with homonymous hemianopsia: What is a common problem?
- they often run into things because they can’t see or feel them
- have to teach them how to move their heads as they go
- can also get a focal point of vision loss
What are Rood’s techniques? (list them)
- stretch
- joint manipulation
- cutaneous stimulation
- icing
- deep pressure
- neutral warmth (with maintained touch)
- vestibular stimulation
- auditory
- visual
- gustatory
- olfactory
Rood’s techniques: stretch types
- facilitatory
- inhibitory
What is a facilitatory stretch?
quick stretch gets the person to contract
- calls for motion
- creates increase in muscle threshold to create contraction
What external stimulus can be used for facilitatory/inhibitory stretch?
vibratory massager
vibratory massager: inhibitory frequency
≤ 100 Hz
vibratory massager: facilitatory frequency
≥ 100 Hz
Inhibitory stretch
- long stretch
- allows to possibly get more ROM
types of joint manipulation (Rood’s)
- compression
- distraction
Compression is (facilitatory/inhibitory)
facilitatory
Distraction is (facilitatory/inhibitory)
inhibitory
Why is joint compression facilitatory?
- usually happens through WB and creates cocontraction at the joint
- anything that creates force through the joint will cause contraction
types of cutaneous stimulation
- light touch
- slow stroking
- maintained
cutaneous stimulation: light touch
- down paraspinals, will likely contract
- facilitatory
- people have different thresholds to elicit contraction
cutaneous stimulation: slow stroking
- slow stroke over a muscle belly
- inhibitory
cutaneous stimulation: maintained
- underarmor, wrapping
- not super tight
icing techniques (timing)
- quick
- maintained
- prolonged
icing: quick
- single, quick stroke
- facilitatory
icing: maintained
- 3-5 sec
- builds up, then get them to contract
- facilitatory
Why does maintained icing cause facilitation?
neuro input: muscle is cold and wants to contract
prolonged icing
- 15-20
- inhibitory
- will reach a point where it relaxes
