1. Neural tissue mobilization (NTM) is a clinical technique that applies the mechanics and physiology of the nervous system and how it relates to and integrates with the musculoskeletal system.
2. NTM uses specific movements and positions to assess nerve mobility and elicit symptoms in order to determine the source of a patient's pain. Common tests include the median, ulnar, and radial nerve tests.
3. A positive NTM test is indicated by reproduction of the patient's clinical symptoms that change with structural differentiation. NTM can help diagnose neurogenic causes of pain and guide effective treatment.
2. WHAT IS NEURODYNAMICS
Eg : Excessive pronation at ankle (mechanical); Diabetic neuropathy (physiological)
INTERLINKED
3. BENEFITS OF CLINICAL NEURODYNAMICS
Safer
More effective
Link diagnosis and treatment to causal mechanisms
Integrates neural aspects with the musculoskeletal system
Systematic
4. CLINICAL NEURODYNAMIC DEFINITION
• Clinical application of mechanics and physiology of nervous system as
they relate to each other and are integrated with musculoskeletal function
MECHANICS
PHYSIOLOGY
5. INTEGRATIVE FUNCTION – NERVOUS SYSTEM &
MUSCULOSKELETAL SYSTEM
Mechanical Interface: Tissues most anatomically adjacent to the nervous system that
can move the nervous system. Eg: Supinator muscle (Radial nerve)
6. TERMINOLOGIES
• Convergence: Nerve move toward the part where tension is applied.
• Sliders: movement of nerve without stretching (stretch at one joint
and relax at other joint) – goal is to produce gliding movement in
relation to surrounding tissues
• Tensioners: It produces an increase in tension in neural structures. -
goal is to produce tension in the certain part of peripheral nerve.
7. TERMINOLOGIES
• Structural Differentiation : When the therapist moves the relevant neural
structures without moving the adjacent musculoskeletal structures
Structural differentiation is
used in
ALL
Neurodynamic tests in
8. INDICATIONS
• Use in non-irritable conditions (neuropathic/neurogenic)
• For pathomecanical causes:
- Fibrosis
- Connective tissue adhesions
- Restriction of normal tissue mobility
9. CONTRAINDICATIONS
• Malignancies of the nervous system or vertebral column
• Acute inflammatory infections
• Areas of instability
• Spinal Cord Injuries
• Suspected disc lesions
• Cauda equina lesions
• Dizziness related to vertebral artery insufficiencies
• Any central nervous system disorders (e.g. spina bifida, MS)
• Worsening neurological signs
10. TECHNIQUE SELECTION
• Based on categorization of patient’s severity.
• Divided into levels – 0, 1, 2, 3a, 3b, 3c & 3d
• Level 0 – Patients who are contraindicated, Severe pain, Severe
psychological influence, highly unstable condition, worsening rapidly.
• Level 1: Acute/ Limited examination, Highly irritable symptoms,
symptoms easily provoked, take long time to settle.
• Level 2: Standard/ Subacute, Not particularly irritable, stable conditions
are present, no significant neurological symptoms are present.
• Level 3: Chronic / Advanced, Pain is difficult to evoke, need for more
specificity & sensitivity testing.
• 3a – Neurodynamic sensitization, 3b - Neurodynamic sequencing, 3c –
Multistructural examination, 3d – Symptomatic position / movement.
12. 1. Explanation to the patient :
If it is alright with you, I’d like to perform some movements on your arm. This helps
me evaluate the problem and may or may not produce some mild symptoms. It doesn’t
matter either way, but I need to know precisely what happens, as it happens. So,
without moving your body part, please tell me verbally what happens. Do you
understand? Now, are you comfortable and relaxed?
2. Test the unaffected side first
3. Maintain each movement precisely
4. Be gentle, Do Not hurry
5. Evoke vs Provoke
6. Short duration of testing : < 10 secs
7. Observe the site & quality of symptoms
8. Perform structural differentiation
9. Watch for antalgic movements
13. DIFFERENTIAL DIAGNOSIS
To distinguish between origin of the symptoms the following should be
considered
• Be aware of the expected normal response
• Know all details of all the symptoms
• Know the symptoms in the starting position
• Monitor symptoms throughout the procedures
• Notice when pain starts
• The effect of sensitizing additions / subtractions on the symptoms. This is
considered an important factor to distinguish that the positive test is due
to neural tissue affection.
