Deep Tendon Reflexes / Tone Flashcards
1
Q
Muscle Receptors
A
- Golgi Tendon Organs (GTO)
- Muscle Spindle
2
Q
GTO
A
- Golgi Tendon Organs
- Respond to excessive tension in tendon near insertion (Tension Based)
- Causes muscle to decrease tension
3
Q
Muscle Spindle
A
- Respond to quick stretch of the muscle
- Causes muscle to contract
4
Q
DTR’s test what?
A
- Afferent and efferent neuron pathways
5
Q
Responses can help determine what?
A
- UMN and LMN impairments
6
Q
LMN
A
- Lower Motor Neuron Liesion
- Flaccid, diminished reflex, twitching
- Extremities
- Hyporeflex
7
Q
UMN
A
- Upper Motor Neuron Liesion
- Excessive reflex or too much tone to elicit
- Tone, Problems with ROM
- Brain and Spinal Cord
- Hyperreflex
8
Q
When Testing
A
- Limbs should be in a relaxed position
- Muscles at mid range or slight stretch
- Compare contralateral side
9
Q
Grades
A
0 Absent 1+ Trace 2+ Normal 3+ Brisk (Strong Response) 4+ Clonus (rhythmic contraction)
10
Q
1+ 2+ 3+ grades?
A
- Are normal unless asymmetric or dramatic deference between UE and LE
11
Q
0, and 4 grades?
A
- Are usually considered abnormal
12

14
Q

15
Q
