One of the most common questions patients ask during an osteopathic treatment is:
“What was that clicking sound?”
For some people, the sound can be surprising, while others find it deeply satisfying. The clicking or popping noise that occasionally occurs during osteopathic treatment is known as a joint cavitation, and despite many myths, it is not bones grinding together or joints being put back into place.
In fact, for carefully selected patients, these techniques can be an effective way of improving movement, reducing pain, and helping the body return to a more comfortable state.
The clicking sound often occurs during a technique called a High Velocity Low Amplitude (HVLA) thrust, commonly referred to as osteopathic manipulation.
Research suggests that the sound is produced by a process known as cavitation within the joint. Synovial joints, such as those found in the spine, contain fluid and dissolved gases. When the joint surfaces are gently separated during manipulation, a rapid change in pressure occurs, causing gas bubbles to form and collapse within the fluid.
This process creates the characteristic “pop” or “click” that many people hear.
Studies using MRI imaging have demonstrated that the sound is associated with gas bubble formation within the joint rather than bones cracking or rubbing together.
Interestingly, no.
While many patients associate the sound with a successful treatment, research suggests that the therapeutic benefits of manipulation are not dependent upon hearing a click.
Osteopaths often achieve excellent results using soft tissue work, articulation, stretching, exercise prescription, and cranial or functional techniques without any audible cavitation.
The sound is simply a by-product of the technique rather than the goal itself.
Although researchers continue to investigate the exact mechanisms, several effects have been identified.
Restricted joints can sometimes move less freely due to stiffness in surrounding tissues, muscle guarding, or changes in joint mechanics.
Manipulation may help restore movement to these joints, allowing them to move more comfortably and efficiently.
Studies have shown that spinal manipulation can stimulate the nervous system and alter pain processing pathways.
This may lead to a reduction in pain sensitivity and an improvement in symptoms, particularly for conditions such as:
Following manipulation, many patients report feeling looser and more relaxed.
Research suggests that manipulation may influence muscle tone through neurological mechanisms, helping overactive muscles reduce their protective guarding response.
Pain and injury can alter how the brain perceives movement and posture.
Manual therapy may provide valuable sensory input to the nervous system, helping improve proprioception—the body’s awareness of position and movement.
Clinical guidelines in the UK and internationally support manual therapy, including manipulation, as one possible component of care for certain musculoskeletal conditions when used alongside exercise, education, and self-management strategies.
Research has found evidence that spinal manipulation can provide short-term improvements in pain and function for some patients experiencing:
However, manipulation is not a cure-all and works best as part of a comprehensive treatment approach tailored to the individual.
When performed by a qualified osteopath who has completed a thorough assessment and screening process, manipulation is considered a safe treatment option for appropriate patients.
Not everyone is suitable for HVLA techniques. Osteopaths carefully consider factors such as:
There are always alternative techniques available if manipulation is not appropriate or desired.
At its heart, osteopathy is not about making joints click.
The goal is to understand why a person’s body is experiencing pain, restriction, or dysfunction and to help restore balance through a range of hands-on techniques, movement advice, and lifestyle support.
For some patients, manipulation can be a useful tool that helps improve mobility and reduce discomfort. For others, gentler approaches may be more appropriate.
The clicking sound itself is simply one small part of a much bigger picture: helping the body move, adapt, and function at its best.
