Study Notes

Neurological Testing vs Neurodynamic Assessment

Neurological testing assesses the ability of nerves to conduct messages by evaluating afferent (sensory), efferent (motor), or combined (deep tendon reflexes) functioning of the nervous system.
Neurodynamic assessment assesses the sensitivity of nerve structures, particularly when they are put on tension.

Principles of Neurodynamic Assessment

Neurodynamic testing determines whether there is increased sensitivity of the nerve itself or whether there is a loss of conduction.
Neurodynamic testing can be quite provocative, so it should only be performed when it will provide useful information that has the potential to change one's thinking or management plan.
The neural structures being assessed are longer than either the articular or muscular structures.

Neurodynamic Testing Procedures

Neurodynamic testing procedures progressively tension the neural structures.
Sensitising maneuverers are used to either increase or decrease tension on the neural structures without affecting the other, shorter structures.
Examples of sensitising maneuverers include:
- Flexing the hip with the leg straight to test for tension on the sciatic nerve.
- Dorsiflexing the ankle to increase tension on the sciatic nerve.

Interpreting Neurodynamic Test Results

A response to the sensitising manoeuvres indicates that neural structures are being assessed by the movements.
The response to the sensitising manoeuvres must be compared to the opposite side or clinical judgement to determine if the range of movement in the test is normal for the individual.
A positive test does not necessarily mean treatment should target neural sensitivity.

Lumbar Spine Instability

The way someone moves can predispose them to developing low back pain.
Habitual patterns of movement can predispose individuals to developing LBP.
Maladaptive responses to pain can lead to further injury.

Muscle Activation and Movement Coordination

Muscle activation and movement coordination are important for spine stability and movement.
Altered muscle activation strategies in response to pain can lead to maladaptive movement patterns.
Assessment of lumbar spine clinical and structural instability is important for developing effective treatment plans.

Neurodynamic Treatment Techniques

Neurodynamic treatment techniques are intended to reduce the sensitivity of movement of the nerves.
Treatment techniques can be adjusted to maximise the change in the targeted movement.
Reassessment is critical to ensuring the relevance of the treatment.

Slider and Tensioner Techniques

Slider techniques are analogous to Grade I or II treatment techniques.
Tensioner techniques are similar to Grades III and IV treatment techniques.

Summary of Neurodynamic Testing and Treatment

Neurodynamic testing will be positive when a nerve is irritated by an interface or has increased sensitivity of the nerve itself.
The tests put tension on the entire length of the structure from the nerve roots to the peripheral receptors.
Treatment will target the nerve structures when either the interface cannot be altered directly or the irritation has been present for a period of time such that the nerve itself has become sensitised.### Pain-Related Adaptive Inhibition and Impairments
Pain-related adaptive inhibition can occur in the deep stabiliser muscles of the lumbar spine (TrA, Internal Oblique, Diaphragm, and Pelvic floor muscles) in individuals with LBP and SIJ dysfunction.
This inhibition can lead to impaired movement control and coordination in the lumbopelvic region, with or without associated mobility deficits and referred pain to the leg.

Protective Response and Adaptive Co-Contraction

When people experience low back pain, they naturally respond by protecting the affected area, which often involves increasing co-contraction of the 'global' muscles that span the entire spinal region.
This increased stiffness and altered movement patterns are an adaptive response in the short term, allowing for the healing process to proceed without ongoing injury.
However, if this protective movement pattern persists, it can reduce the necessary movement for normal spinal nutrition and remodelling of damaged tissues, potentially placing greater strain on previously damaged tissues.

Assessing and Recovering Muscle Activation Patterns

Assessing and recovering individual muscle activation patterns of deep stabilisers can help reduce the adaptive co-contraction of global (superficial) mobilisers, reducing the load and pain irritability, and regaining segment control during functional activity.
Addressing muscle activation impairments plays a crucial role before progressing with core muscle strength training programs in clients with movement control or coordination impairments due to neuro-musculoskeletal pain conditions of the lumbopelvic region.

Muscle Re-Education and Motor Learning Approach

Muscle re-education can be an effective strategy to address presenting ongoing impairments, regardless of the type of altered motor or muscle recruitment strategy.
Enhancing neuromuscular performance can improve the ability of the muscle to resist deformation and react by generating the desired amount of force to carry out the planned movement.
Muscle re-education involves four stages: Attention, Intention, Action, and Reflection on Action.

Strategies for Assisting Clients in Activating Lumbar Spine Stabilising Muscles

Several strategies can be used to assist clients in activating their lumbar spine stabilising muscles, including:
- Conscious activation of TrA and IO using exhalation
- Activating pelvic floor muscles
- Body position changes (gravity on abdominal wall)
- Lumbar multifidus activation using overflow of muscle contraction from isometric gluteus maximus contraction

Dynamic Control and Functional Re-Education

Stage 3 of muscle re-education involves dynamic control and functional re-education, which includes:
- Increasing the level of challenge in more functional and gravity-dependent positions
- Less assistance
- Targeted toward the goals of clients
- Task-specific focus for neuro-musculature re-education
- Moving from foreign to familiar environments
- Adding endurance

Framework for Core Stability Training

The framework for core stability training involves three stages:
- Stage 1: Pain control (stabilisation, short-term)
- Stage 2: Begin controlled loading (commence usage that has a positive effect on the affected area through mobilisation exercises)
- Stage 3: Dynamic control and functional re-education

Applying the Framework for Core Stability Training

The framework can be applied in a non-linear fashion for clients with re-injury or chronic low back pain, with force moderation for presentations at different stages of healing.
Clients with ongoing or recurring episodes of pain require an approach that includes more dynamic stabilisation to assist in resolving impairments.
Pain control and biomechanical counselling are essential elements for all clients, regardless of the stage of healing.

Exercise Prescription and Assessment

Exercise assessment involves observing movement and using objective measures of strength, such as the Biering-Sorensen test and lateral stability using the side plank.
Measuring strength isometrically can provide valuable information, and exercises can be progressed to more functional and dynamic activities.

Deep Trunk Stabiliser Muscle Activation

The deep trunk stabiliser muscle activation helps to improve lumbar stability through three mechanisms:
- Applying tension to the thoracolumbar fascia (mechanical stiffness)
- Increasing intra-abdominal pressure (in coordination with the diaphragm and pelvic floor muscles)
- Providing a small amount of flexion torque
