Exploring the Sound of Synovial Joint Distraction: Is it a Gas Bubble or Something Else?

joint cracking

When we experience a “pop” or “snap” sound during the distraction of a synovial joint, most people wonder what exactly causes this audible noise. While there is a prevailing belief that it’s a gas bubble that produces sound, a new, yet simple, hypothesis challenges this notion.   Dr. Jerome Fryer, the Chief Innovation Officer at Dynamic […]

Facet Joint Syndrome – Review and Models

Facet Joint Syndrome

What is Facet Joint Syndrome? recumbency and recovery Facet syndrome is a condition that occurs when the facet joints in the spine become damaged or degenerated. The facet joints are small joints located between the vertebrae in the spine, and they help to support the spine and allow it to move smoothly. When these joints […]

Differences in force-time parameters and electromyographic characteristics of two high-velocity, low-amplitude spinal manipulations following one another in quick succession

Cervical Multilevel Model, velocity

Goal of the Study? The goal of this study 1 was to compare the force-time parameters (magnitude of a force, preload force and duration of thrusts) and electromyographic characteristics (reflex or response) between two spinal manipulations delivered following one another in quick succession if the first thrust was not associated with audible cavitation.  Why are […]

Cavitation – Practitioner Experience Best Indicator of Success

cavitation, spine, joints

Practitioner Experience Best Indicator of Success in Cervical Spine Manipulation Cavitation Cervical spine studies have historically indicated that manipulation (and the generation of cavitation) by a qualified practitioner is the most effective means of treatment for neck pain, far exceeding placebos or exercise. Though there are various definitions and modalities of cervical manipulation, in general, […]

Synovial Fold -Noise- and Suction

Chiropractic done by hand

Synovial Fold -Noise- and Suction. With recent data collected using MRI on the metacarpophylangeal joint, the current idea around a cracking joint appears to have been seriously challenged. Current belief is that cavitation, a process of bubble formation and subsequent collapse, is responsible for the noise. But curiously, when you look up ‘cavitation’, it is an […]
