Sensory Motor Reflexes Flashcards
Compression of anterior nerve root
-muscle weakness
Causes of compression
- disc herniation
- DDD
- recent trauma
- inflammatory changes
- tumors
0/5
complete paralysis
no contraction
1/5
trace of movement
feel contraction, but no movement
2/5
moderate to severe paralysis
movement without gravity
3/5
moderate paralysis
active mvmnt against gravity
4/5
mild paralysis
active mvmnt
mild resistance against 2 fingers
5/5
normal strength/mvmnt

Deficit Phenomenon
loss of normal neurological function
==>reduced tone, stretch reflexes, muscle strength, volume
Release Phenomenon
exaggerations or perversions of normal neurological function due to a loss of cortical inhibition
Wexler Scale
grading reflexes
- 0=absent
- 1=hypoactive
- 2=normal
- 3=hyperactive
- 4=hyperactive with sustained or transient clonus

T7-T9
Middle abdominal reflex segmental innervation?
T9-T11
Lower abdominal reflex segmental innervation?
T11-T12
Lower abdominal reflex peripheral innervation?
intercostal
