Q

List 2 rationales behind the concept of neural tension testing and neural mobilization.

A
  1. Neural tissue is mobile: There is sufficient biomechanical evidence to support the contention that when stretched, nervous tissue undergoes strain and glides within its interfacing tissue.
  2. Neural tissue can be injured

Q

Q

What 4 things should be considered/examined during a neural tension test?

A
  1. Whether the test reproduces the patient’s symptoms
  2. Whether there is an increase in tissue resistance or a decrease in ROM of the nerve on one side of the body as compared with the other side
  3. Whether the patient’s responses are different from that which occurred on the unaffected side, or that which is expected for asymptomatic subjects
  4. Whether the symptoms can be altered by the addition or subtraction of a sensitizing maneuver

Q

What concept should be used to assist with diagnosing nerve impairments?

A
  1. Structural differentiation
  2. This entails altering the pain provoking position or movement in such a way that one structure is incriminated as a source of symptoms while another is eliminated from contention

17
Q

PT must determine whether the involved tissues are _____ or _____ or both.

A

Intraneural

Extraneural

18
Q

What is the difference between intraneural and extraneural tissue?

A
  1. An intraneural tissue injury refers to an injury to conducting or connective nervous tissue,
  2. An extraneural injury refers to an injury to the nerve bed or interfacing structure
19
Q

If the affected tissue is ______, then the symptoms should ‘fit’ with nerve anatomy, especially in relation to the level of involvement.

A

Intraneural

20
Q

What 4 structures should be the focus of treatment if the injury is intraneural?

A
  1. Upper motor neurons
  2. Lower motor neurons
  3. Nerve roots
  4. Nerve
21
Q

Sometimes symptoms change with neural testing because the nerve is healthy, but _______.

A

It is attached to sensitive or pathological structures (extraneural tissue)

22
Q

List 5 common areas for nerve injury. Why are these common areas for injury?

A
  1. Soft tissue, osseous or fibro-osseus tunnels, because of the compression and increased friction associated with decreased space
  2. Nerve branches, because of the stretch caused by the decrease in the ability of the nerve to glide as a response to movement at these locations
  3. Where nerves are fixed, because of the stretch caused by the decrease in the ability of the nerve to glide as a response to movement at these locations
  4. Friction points
  5. Tension points, because of the stretch caused by the decrease in the ability of the nerve to glide as a response to movement at these locations.
23
Q

True or False: The location of the symptoms pinpoints the location of the nerve injury.

A

FALSE

24
Q

____ at non-vulnerable spots can affect vulnerable sites.

A

Trauma

25
Q

List 3 intervention considerations employed during treatment.

A
  1. Patient positioning is the same for both examination and treatment
  2. Patient positioning is intended to stretch neural tissue
  3. Treatment is directed into the position, movement, or movement combination that produced symptoms
26
Q

True or False: Treatment should provoke the patient’s symptoms and should start at the area of symptoms.

A

FALSE

Treatment should not provoke symptoms and should be well removed from the area of symptoms.

27
Q

Treatment of _____ lesions can be performed in neural tension positions.

A

Extraneural

28
Q

Treatment aggressiveness should be determined by the ____ of the condition

A

Irritability

29
Q

How should irritable conditions be treated?

A

Irritable conditions should be treated with techniques that do not take the structure to the end range position for that patient and do not provoke pain.

30
Q

How can stiff conditions be treated?

A

Stiff conditions can be treated with techniques that take the structure through the end range position for that patient and should also not provoke pain.

31
Q

What grades of mobilization should be used to maintain neural mobility?

A

Maintain neural mobility by performing Grade I or Grade II oscillation range of motion into the test position for a particular nerve at any of the joints that the nerve crosses. (especially if the condition is characterized by being ‘irritable’ = pain occurs before the end feel)

32
Q

What grades of mobilization should be used to increase neural mobility?

A

Increase neural mobility by performing Grade III or Grade IV oscillation range of motion into the test position for a particular nerve at any of the joints that the nerve crosses. (especially if the condition is characterized by being ‘stiff’ = pain occurs after the end feel)

33
Q

What is flossing?

A

Stretch one end of the nerve while keeping slack on the other end of the nerve

34
Q

List 8 precautions/ contraindications to neural mobilization techniques.

A
  1. Dizziness secondary to vertebrobasilar insufficiency
  2. If a circulatory disorder is present
  3. Malignancy
  4. Acute inflammatory infection of the nervous system
  5. Rapidly worsening symptoms

A

TRUE

36

True or False: Neural mobilization is more effective than other forms of intervention to reduce pain and disability related to nerve related chronic musculoskeletal pain.

A

FALSE

No more effective than other interventions used to reduce pain

2. Neck-arm pain

38

A

TRUE

39
