![]() ![]() The passive subsystem allows the lumbar spine to support a limited load (approximately 10 kg) that is far less than body mass. The passive subsystem consists of the spinal ligaments and facet articulations between adjacent vertebrae. The stabilizing system has been divided into 3 distinct subsystems: the passive subsystem, the active muscle subsystem, and the neural subsystem (Panjabi, M.M). Panjabi defined core stability as "the capacity of the stabilizing system to maintain the intervertebral neutral zones within physiological limits". The stability ofthe lumbopelvic region is crucial to provide a foundation for movement of the upper and lower extremities, to support loads, and to protect the spinal cord and nerve roots (Panjabi, M.M). Mcgill, S.M, Mggill, S.M et al, Panjabi, M.M,). The term core has been used to refer to the trunk or more specifically the lumbopelvic region of the body (Bergmark, A. When the system works efficiently, the result is appropriate distribution of forces optimal control and efficiency of movement adequate absorption of ground-impact forces and an absence of excessive compressive, translation, or shearing forces on the joints of the kinetic chain. ![]() ![]() These muscles help to stabilize the spine, pelvis, and kinetic chain during functional movements. The core musculature is composed of 29 pairs of muscles that support the lumbopelvic-hip complex. As the patient makes the transition to the standing position, sensory-motor training is used to stimulate the sub-cortex and provide a basis for more advanced functional movement exercises, which promote balance, co-ordination, precision, and skill acquisition. When this has been mastered, advanced lumbo-pelvic stability exercises using the Physioball are added for greater challenge. Next, fundamental lumbopelvic stability exercises are introduced, teaching the patient to activate the deeper core musculature. The program starts with restoration of normal muscle length and mobility to correct any muscle imbalances. Weakness or lack of sufficient co-ordination in core musculature can lead to less efficient movements, compensatory movement patterns, strain and overuse and injury.
