How Butler Neurodynamic Techniques Can Improve Your Nerve Health and Function
What are Butler Neurodynamic Techniques?
Butler neurodynamic techniques are a set of assessment and treatment methods for physical health and sensitivity issues related to peripheral and central nervous system-based pain presentations. They are based on the concept of neurodynamics, which is the study of how nerves move and function in relation to other structures in the body.

Butler neurodynamic techniques were developed by David Butler, a physiotherapist and educator who founded the Neuro Orthopaedic Institute (Noigroup) in Australia. He is also the author of several books on neurodynamics, such as The Sensitive Nervous System and Neurodynamic Techniques Handbook & Videos.
Definition and background
Butler neurodynamic techniques are defined as "active and passive assessment and treatment strategies for physical health and sensitivity issues related to peripheral and central nervous system-based pain presentations" . They aim to restore the mobility and function of nerves that have restricted longitudinal movement or are compressed by other tissues.
Butler neurodynamic techniques are based on the premise that nerves are dynamic structures that can slide, glide, stretch, bend, and twist in response to various movements and postures. However, when nerves are injured or irritated, they can become sensitive, inflamed, or adhered to surrounding structures, resulting in pain, numbness, tingling, weakness, or reduced range of motion.
Butler neurodynamic techniques use specific movements and positions to test and mobilize the nerves of the upper and lower extremities, as well as the spinal cord and meninges. They also incorporate education on neurobiology and pain science to help patients understand their condition and reduce their fear-avoidance behaviors.
Benefits and applications
Butler neurodynamic techniques have several benefits and applications for patients with various types of nerve-related pain conditions, such as:
Neuropathic pain: pain caused by damage or dysfunction of the nervous system, such as diabetic neuropathy, postherpetic neuralgia, or carpal tunnel syndrome.
Neurogenic pain: pain caused by compression or irritation of a nerve root or peripheral nerve, such as radiculopathy, sciatica, or thoracic outlet syndrome.
Neuroplastic pain: pain caused by changes in the central nervous system due to chronic or recurrent pain, such as central sensitization or phantom limb pain.
Some of the benefits of Butler neurodynamic techniques include:
Reducing nerve sensitivity and inflammation by improving blood flow and oxygen delivery to the nerve tissue.
Restoring nerve mobility and function by breaking down adhesions and scar tissue that limit nerve movement.
Enhancing joint range of motion and muscle strength by facilitating nerve conduction and muscle activation.
Improving pain perception and coping skills by educating patients on neurobiology and pain mechanisms.
Preventing recurrence or worsening of symptoms by teaching patients self-management strategies and exercises.
How to Perform Butler Neurodynamic Techniques?
Butler neurodynamic techniques can be performed by trained health professionals, such as physiotherapists, chiropractors, osteopaths, or massage therapists, who have knowledge and skills in neurodynamics and pain science. They can also be taught to patients as part of their home exercise program.
General principles and precautions
Butler neurodynamic techniques involve two main types of movements: sliders and tensioners. Sliders are movements that cause the nerve to slide relative to the surrounding tissues, without increasing the tension on the nerve. Tensioners are movements that cause the nerve to stretch or elongate, increasing the tension on the nerve.
Sliders are usually used for initial assessment and treatment, as they are gentler and less provocative than tensioners. Tensioners are used for more advanced or resistant cases, as they are stronger and more aggressive than sliders. Both sliders and tensioners can be performed actively by the patient or passively by the therapist.
Some of the general principles and precautions for performing Butler neurodynamic techniques are:
Start with a thorough history and physical examination to identify the source and nature of the nerve problem.
Choose the appropriate technique for the specific nerve involved, based on anatomical and biomechanical considerations.
Apply the technique gradually and gently, avoiding sudden or forceful movements that may aggravate the nerve.
Monitor the patient's response and feedback, adjusting the technique accordingly.
Stop the technique if the patient experiences any adverse reactions, such as increased pain, numbness, tingling, or weakness.
Combine the technique with other interventions, such as manual therapy, exercise, or education, to optimize the outcomes.
Specific techniques for different nerves
Butler neurodynamic techniques can be applied to various nerves of the upper and lower extremities, as well as the spinal cord and meninges. Here are some examples of specific techniques for different nerves:
The median nerve is one of the main nerves of the arm and hand. It originates from the brachial plexus in the neck and passes through the shoulder, elbow, wrist, and palm. It innervates most of the muscles of the anterior forearm and hand, as well as some of the skin of the palm and fingers.
A common condition affecting the median nerve is carpal tunnel syndrome, which is caused by compression of the nerve at the wrist. Symptoms include pain, numbness, tingling, or weakness in the thumb, index finger, middle finger, and half of the ring finger.
A common technique for assessing and mobilizing the median nerve is called Upper Limb Neurodynamic Test 1 (ULNT1) . It involves placing the arm in a position that maximizes the tension on the median nerve. The position can be modified by changing various components, such as shoulder abduction, elbow extension, wrist flexion, finger flexion, forearm supination, shoulder girdle depression, neck lateral flexion, or scapular protraction.
The technique can be performed as a slider or a tensioner. A slider involves moving one component in one direction while moving another component in the opposite direction. For example, moving the elbow into extension while moving the neck into lateral flexion away from the tested side. A tensioner involves moving all components in the same direction to increase tension on the nerve. For example, moving both elbow into extension and neck into lateral flexion toward the tested side.
The radial nerve is another main nerve of the arm and hand. It also originates from the brachial plexus in the neck and passes through the shoulder, elbow, wrist, and back of the hand. It innervates most of the muscles of the posterior arm and forearm, as well as some of the skin of the back of the hand and fingers.
A common condition affecting the radial nerve is radial tunnel syndrome, which is caused by compression of the nerve at the elbow. Symptoms include pain, numbness, tingling, or weakness in the back of the forearm, wrist, or hand.
A common technique for assessing and mobilizing the radial nerve is called Upper Limb Neurodynamic Test 2 (ULNT2) . It involves placing the arm in a position that maximizes the tension on the radial nerve. The position can be modified by changing various components, such as shoulder abduction, elbow flexion, wrist extension, finger extension, forearm pronation, shoulder girdle elevation, neck lateral flexion, or scapular retraction. 71b2f0854b
