For many decades, the physical mechanism that causes the cracking sound as a result of bending, twisting, or compressing joints was uncertain. Suggested causes included: Cavitation within the joint—small cavities of partial vacuum form in the synovial fluid and then rapidly collapse, producing a sharp sound. [6] [7] Rapid stretching of ...
Further research into crackling noise was done in the late 1940s by Charles Francis Richter and Beno Gutenberg who examined earthquakes analytically. Before the invention of the well-known Richter scale, the Mercalli intensity scale was used; this is a subjective measurement of how damaging an earthquake was to property, i.e. II would be small vibrations and objects moving, while XII would be ...
Hori et al. regard sleep onset hypnagogia as a state distinct from both wakefulness and sleep with unique electrophysiological, behavioral and subjective characteristics, [10] [12] while Germaine et al. have demonstrated a resemblance between the EEG power spectra of spontaneously occurring hypnagogic images, on the one hand, and those of both ...

Forward head posture (FHP) [1] is an excessively kyphotic (hunched) thoracic spine. It is clinically recognized as a form of repetitive strain injury. [citation needed] The posture can occur in dentists, [2] surgeons, [3] and hairdressers, [4] or people who spend time on electronic devices.
This may be accompanied by a snapping or popping noise and pain or discomfort. Pain often decreases with rest and diminished activity. Pain often decreases with rest and diminished activity.
