![]() intramuscular injection of hypertonic saline ) or in clinical MSK pain populations. In recent years, an increasing number of studies have quantified changes in muscle synergies during either experimentally-induced pain (e.g. Understanding the behavioural effects of MSK pain without biomechanical constraints and therefore in the framework of muscle synergies may elicit more consistent patterns of motor control adaptations, than analysis within a limited motor solution subspace. One solution thought to be used by the CNS to solve the DOF Problem, is to reduce the number of dimensions into discrete sets of muscle groups, known as muscle synergies. In the DOF Problem, the central nervous system (CNS) has to cope with an apparent excess of muscles needed to perform a given task. the Degree of Freedom (DOF) Problem of Bernstein ). This is perhaps unsurprising given that assessing motor control within a small motor solution subspace during pain ignores the number of dimensions of the neuromuscular system (i.e. A common finding of many studies which investigated the influence of MSK pain on individual muscle control is the large variability between-individuals and between-motor tasks. The relationship between pain and altered motor control in MSK pain disorders has been commonly investigated on individual muscles, or on a small number of muscles, using movement assessments requiring a small motor solution subspace. An important premise behind exercise interventions is that disturbed motor control not only occurs because of pain, but also contributes to pain. Although the resolution of pain is the primary aim of most interventions, some conservative treatments such as exercise have the additional aim of enhancing or restoring motor function. These disorders have a substantial impact on an individual’s quality of life. Musculoskeletal (MSK) pain disorders are a group of disorders associated with nociception experienced within the MSK system (muscles, ligaments, joints, and tendons). ![]()
