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
Q
Biceps
A
- Musculocutaneous
- C5 C6
13
Q
Brachioradialis
A
- Radial
- C5 C6
14
Q
Triceps
A
- Radial
- C6 C7
15
Q
Patellar
A
- Femoral
- L2 L3 L4
16
Q
Hamstring
A
- Tibial
- L5 S1 S2
17
Q
Achilles
A
- Tibial
- S1 S2
18
Q
Abnormal Tone
A
- Hypertonia (UMN)
- Hypotonia (LMN)
- Dystonia (UMN)
19
Q
Spasticity
A
- Hypertonia from a quick stretch
- UMN injury
20
Q
Rigidy
A
- Hypertonisity throughout ROM
- COG wheel rigidity
21
Q
Flaccidity
A
- No detectable tone
- LMN injury
22
Q
Dystonia
A
- Disordered tone, seen by a writhing movements
- UMN injury
