What are the 2 questions you need to ask yourself when testing spinal reflexes?
|
1. Does it work? -considers LMN
2. Is it normal?- considers both LMN and UMN |
|
|
What is considered a normal reflex?
|
Normal reflex is immediate on stimulus, lasts for duration of stimulus, stops immediately when stimulus is removed
|
|
|
How are reflexes graded?
|
0 = Absent (LMN problem either central or peripheral)
+1 = Depressed - hyporeflexia(LMN problem either central or peripheral) +2= Normal (LMN working normally) +3= Exxagerated hyperreflexia (UMN problem or LMN are inflamed) +4= Very exaggerated (clonus) (UMN problem or LMN are inflamed) |
|
|
What are the 4 components of all reflexes?
|
1. Afferent limb
2. Interneuron 3. LMN (efferent limb) 4. Effector organ |
|
|
What are the 2 types of spinal reflexes?
|
1. Monosynaptic reflexes: afferent neurons go directly to LMN and do not use interneurons
2. Multisynaptic reflexes: multiple interneurons between afferent and efferent loop |
