Neurodynamics[edit | edit source]
Neurodynamics refers to the communication between different parts of the nervous system and to the nervous systems relationship to the musculoskeletal system. It has been shown that the nerves move independently from other tissues. The term Neurodynamics first made an appearance in 1989 and has since been further developed over the last 30 years. Neurodynamics is now seen as an important part of injury assessment and treatment.
Neurodynamics in the sense implied here is the mobilisation of the nervous system as an approach to physical treatment of pain. The treatment and or assessment relies on influencing pain physiology via the mechanical treatment of neural tissues and non-neural structures surrounding the nervous system. This mobilisation activates a range of mechanical and physiological responses in nervous tissues. eg neural sliding, pressurisation, elongation, tension and changes in intraneural microcirculation, axonal transport and nervous impulse movements.
The video below gives a good full description of the principles of neurodynamics
Neural mobilization to treat neurodynamic dysfunction to date is still needing justiifcation through research of high quality homogenous studies. To date however most studies have shown positive therapeutic effects through the use of neurodynamic treatment. 
Neural Basics[edit | edit source]
To apply the principles of neurodynamics a good understanding of the neural basics, as defined below, is needed.
- Neurophysiology - study of the function of the nervous system.
- Neurobiomechanics - based on the research of bioengineering researchers, neuro-surgery, orthopedic surgery and biomechanists, then utilised by neurosurgeons, orthopedic surgeons and by integrated physical medicine practitioners (eg physiotherapists, chiropractors, nurse practicioners). These practitioners focus on aiding people in the restoration of biomechanics of the skeletal system in order to measurably improve nervous system function, health, function, quality of life, reduce pain and the progression of degenerative joint and disc disease.
- Neuropathology- study of diseases of the nervous system.
Two fold Neural Examination involving[edit | edit source]
1.Neural (Traditional) Examination [edit | edit source]
- Neural Subjective
- Dermatomes and myotomes
- Muscle strength
- Romberg’s Test
- Babinski’s Reflex ( Plantar response)
- see also Neurology assessment
2.Neural Provocation Tests [edit | edit source]
For a guide to the below tests, look to the one link here Neurodynamic Assessment
- ULTT1 (median nerve bias)
- ULTT2b (radial nerve bias)
- ULTT3 (ulnar nerve bias)
- PNF (Lhermitte’s Test)
- SLR (sciatic, tibial, and peroneal nerve biases)
- PKB (femoral nerve bias)
- Slump (dura)
Conditions with neurodynamic involvement[edit | edit source]
