- Muscles possessing a local stability role are typically the deepest of all muscles, with a biomechanical advantage to control intersegmental displacement (translation) during functional movements. These structures are not efficient at producing or controlling range of motion.
- All functional movements are seen to create reactive perturbations (displacement) in the spine and proximal motion segments. In normal function, these muscles activate prior to (or simultaneously with) the global muscles in anticipation of this predicted proximal perturbation therefore providing a mechanism of protection against repetitive uncontrolled translation.
- Research has shown that in the presence of pain (or a recent history of pain) or recurrent pain, the normal timing of this feedforward mechanism can be predictably and consistently delayed.
- There are indications to suggest that the consistent failure of this feedforward recruitment contributes to a mechanism of insidious symptom recurrence. Retraining these muscles can significantly reduce the high incidence of musculoskeletal pain recurrence following the first episode
- Clinical tests have been devised to evaluate the recruitment efficiency of these local stabiliser muscles and specific retraining strategies have been developed to recover their recruitment efficiency
- Muscles that have a local stability role are recruited in all functional movements.
- They are the deepest of all muscles and are biomechanically advantaged to control intersegmental displacement/translation by being located close to the axis of motion or by generating fascial tension across multiple segments. Biomechanically, these muscles are not efficient at producing or controlling range of motion
- All functional movements create reactive perturbations (displacement) in the spine and proximal motion segments. In the absence of pain or a history of pain, these muscles activate prior to (or the same time as) the global muscles of range of motion in anticipation of this predicted proximal perturbation to provide a mechanism of protection against repetitive uncontrolled translation. The timing of this anticipatory feedforward recruitment is independent of direction of the force of motion
- Research has shown that in the presence of pain (or a recent history of pain) or recurrent pain, the normal timing of this feedforward mechanism is predictably delayed. This feedforward failure is also independent of the type or the nature of pain.
- In a large proportion of people after the first episode of pain, these muscles fail to recover their feedforward recruitment. There are indications to suggest that this consistent failure of the forward recruitment contributes to a mechanism of insidious symptom recurrence.
- Studies have shown that retraining these local muscles to recover their recruitment physiology and cross-sectional size can significantly reduce the normally high incidence of musculoskeletal pain recurrence after the first episode.
- Trying to retrain local muscles to recover their recruitment deficiencies have not been shown to be effective in making significant changes to pain in the current episode when applied to non-specific pain populations. However, a ‘washout’ effect appears to contribute to this. Based on clinical observations, the subgroup of patients whose symptoms will respond to local muscle retraining can be identified in order to prioritise the patients who should start with early local muscle training in the rehab process as opposed to those who should leave local muscle training to later in the process
- Clinical tests have been devised to evaluate the recruitment efficiency of these local stabiliser muscles in the low back, hip, neck and shoulder
- Specific cognitive retraining strategies have been developed to recover recruitment efficiency so as to improve or correct deficiencies in local stabiliser muscle feedforward recruitment
- Retraining requires an emphasis on progressing and integrating cognitive retraining into function
- The course will allow you to match the level of retraining needed to your patient’s abilities and goals
- Consider the predictable and consistent changes in recruitment neurophysiology of the local stabiliser muscles developed in the presence of pain
- Identify the failure to recover the deficiencies in recruitment of these muscles is strongly linked to pain recurrence
- Identify the subgroup of patients whose symptoms respond to local muscle training, improving clinical decision-making processes regarding who should start with early local muscle training in rehab
- Present clinical testing of recruitment efficiency of the local stabiliser muscles of the low back, hip, knee and shoulder regions
