Spinal mobilization is a type of passive movement of a spinal segment or region. It is usually performed with the aim of achieving a therapeutic effect. Spinal mobilization has been described as a gentle, often oscillatory, passive movement applied to a spinal region or segment so as gently to increase the passive range of motion of that segment or region.
Lumbar spine mobilization is commonly used clinically for the management of low back pain and is a standard manual therapy technique taught in professional-entry physiotherapy courses. Mobilization is defined as low-velocity, passive movement within or at the limit of the joint range.
