The act of intentionally or unintentionally manipulating the lumbar spine to produce an audible “pop” or “crack” is a common occurrence. This phenomenon often involves the release of pressure within the facet joints of the spine, small joints located between vertebrae, resulting from the movement of synovial fluid and gas bubbles.
The perceived relief following the maneuver stems from several factors, including the stimulation of mechanoreceptors, which can temporarily decrease pain perception. Furthermore, muscle relaxation often accompanies the release of tension around the spine. Historically, spinal manipulation has been employed in various cultures for its potential therapeutic benefits in addressing musculoskeletal discomfort and restoring spinal mobility.
