Movements of the head, neck and shoulder girdle are both anatomically and biomechanically linked as many of the muscles producing or controlling movement of the neck also produce and control movement of the shoulder. As the neck and shoulder are functionally interdependent it seems clear both should be assessed and retrained together. It is not just these regions that closely interact in the production of efficient movement. All functional movement utilises synergistic patterns of recruitment between one-joint stabiliser and multi-joint mobiliser muscles. Predictable and consistent impairments in the co-ordinated activation of these synergists has been associated with pain and the site and direction of uncontrolled movement. Changes in their synergies or patterns of recruitment also affects the efficiency of their ability to produce or control movement. Based on a diagnosis of movement control impairment, a clinical reasoning approach can prioritise which synergists are more relevant to test and retrain. Assessing and retraining these muscles to recover their length and recruitment deficiencies can help manage pain, impairment and recurrence.
All functional movement utilises synergistic patterns of recruitment between one-joint stabiliser and multi-joint mobiliser muscles. The proportion of activation and therefore the patterns of synergistic recruitment between these structures varies, depending on the requirements of a particular task. The one-joint muscle synergists are normally more active than their multi-joint mobiliser partners in non-fatiguing ‘normal’ functional activities and postural control tasks. During fatiguing high load or high speed activities the more force and range efficient multi-joint mobiliser synergists contribute the majority of force, with co-contraction of their less force efficient stabiliser partners.
Neurophysiology research has determined that people with pain, a history of previous pain / injury or fatigue, demonstrate aberrant patterns of synergist recruitment in slow, non-fatiguing tasks and movements. These aberrant patterns are related to inhibition or inefficient recruitment of the one-joint stabilisers and increased activation and overactivity of the multi-joint mobiliser synergists. The aberrant patterns appear to be predictable and consistent, and movement tests have been devised to identify when these changes are present. Changes in the contribution of the synergists seems related to changes in sensory motor areas of the brain. This is associated with a predictable inhibition and central ‘down-regulation’ of the stabiliser synergists, while at the same time there is central ‘up-regulation’ and increased central drive of the mobiliser synergists.
Specific global stabiliser muscles in the neck and shoulder do possess an anatomical bias in providing efficient control, a control absent in the presence of movement control impairments. Systematic analysis of the anatomical and biomechanical links between global stabiliser muscles and the diagnosis of the site and direction of movement control impairments allows for clinical prioritisation in both assessment and retraining. Evaluation of the recruitment efficiency of the one-joint global stabiliser muscles and excessive mobiliser substitution throughout range, during non-fatiguing movement testing can identify impairments in these muscles. Specific recruitment efficiency testing of the global stabiliser muscles and subsequent muscle recruitment retraining strategies improve movement efficiency of the neck and shoulder.
Specific testing and inhibitory lengthening techniques can also be employed so as to regain extensibility and reduce recruitment overactivity in the mobiliser synergists of the neck and shoulder. Retraining strategies can be developed to restore optimal movement control to manage symptoms and improve movement. Retraining requires an emphasis on progressing cognitive retraining into function. The course will allow you to match the level of retraining to your patient’s abilities and goals.
