Q

How is performed the dematome procedure?

A

-area to be tested has to be exposed

-test an unrelated body party (face/leg) to check pt understanding

-ask pt to close eyes

-test the entire dermatome,proximal to distal

-test bilaterally at the same time

-start with light touch and if impaired progress to test with sharp/dull or cold/hot

Q

How to test the myotome?

A

To test the muscular function.

-pt is positioning usually sitting

-PT position joint to be tested in neutral position

-“hold this position and don’t let me move u”

-PT applies manual resistance for 5-8seconds while pts resists movement

-test bilaterally whenever possible

34
Q

What is the Jendrassik maneuver?

A

Distraction technique
LEs: ask pt to cross their leg and try to isometric Abducts the les

UEs: ask pt to clasp their hands and try to pull it apart

35
Q

What is the DTR(deep tendon) reflexes grading?

A

0: no response
1+: decreased response
2+:normal response
3+: exaggerated response
4+: clonus/very brisk

36
Q

What are the 4 cervical special tests?

A

1- Cervical distraction test

2- Spurling’s or foraminal compression test

3- upper limb tension tests (medial nerve,radial nerve and ulnar nerve

4- Sharp purser test ( subluxation of c1/c2)

37
Q

What is the purpose of the Cervical distraction test and how it’s performed?

A

The is used when pt is CURRENTLY experiencing radicular symptoms.

PT places one hand under chin and the other hand around the occiptus, lifts upwards to apply a traction to the c spine.

Positive test: radicular symptoms decreased or abolished

38
Q

What is the purpose of the Spurling’s (foraminal compression )test and how it’s performed?

A

PT applies axial load by pressing straight down on pt’s head.
If no symptoms: side flexion to affected side

Positive test: reproduction of radicular symptoms.

39
Q

What is the purpose of the upper limb tension (neurodynamic) test and how it’s performed?

A

Pt is supine

Test unaffected side first

Order of limb position: shoulder-forearm-wrist -elbow

Sensitizing test: contralateral cervical side flexion

Relieving: ipislateral side flexion

40
Q

What is the purpose of the Sharp purser test?

A

To detemine subluxation of C1 on C2

41
Q

What are the two most common brachial plexus injuries?

A

1-Erb duchene paralysis
2-Klumpke’s paralysis

42
Q

What is the Erb duchene paralysis? What is the typical position?

A

Injury to the upper nerve roots c5-c6( upper brachial plexus)

Typical position: waiter’s tip

Arm hanging by the side
Shoulder internal rotation
Elbow extension
Forearm pronation

43
Q

What is the Erb duchene paralysis treatment?

A

Immobilization initially
Positioning
Splinting
gentle ROM
functional training

44
Q

What is the Kumpke’s paralysis? What is the typical position?

A

Injury to the lower nerve roots C8-T1 causing weakness and paralysis in the muscles of the forearm,hand and triceps.

Position: elbow flexion,forearm supination,wrist and MCP extension,PIP and DIP flexion.

Cause “claw hand”

A

D

48
Q

You prescribe the patient an isometric subscapularis exercise. Which of the following innervates the subscapularis muscle?

A

A

49
Q

You perform Spurling’s test. Which of the following is a positive finding for nerve root compression?

a. Pain radiates into the opposite arm to which the head is side flexed during compression.
b. Neck pain is felt but there is no pain radiating into the shoulder or arm.
c.. Pain radiates into the arm toward which the head is side flexed during compression.
d. All of the above are positive findings of the Spurling’s test.

A

C

• Pain radiates into the opposite arm to which the head is side flexed during compression -Incorrect
This is called reverse Spurling’s sign and is indicative of muscle spasm in conditions such as tension myalgia and WADS

• Neck pain is felt but there is no pain radiating into the shoulder or arm - Incorrect
• This does not constitute a positive test.

50
Q

Next, you perform upper limb tension tests. Which of the following statements is false regarding brachial plexus tension testing?

a. The upper limb tension tests are equivalent to the straight leg raise in the lumbar spine.
b. Each test begins by testing the good side first and positioning the shoulder, followed by the elbow, forearm, wrist, and fingers.
c. These tests are designed to stress neurological tissues, but they also stress some contractile and inert tissues.
d. Upper limb tension test are contraindicated in an acute phase of injury and if caudal equina or spinal cord lesions are present.
