When most people picture a chiropractic adjustment, they imagine a manual maneuver with an audible pop. That is one valid approach, but it is not the only one. Torque Release Technique (TRT) is a low-force, instrument-assisted method built on a different model of how to find and correct spinal problems. Understanding the difference helps explain why some practices, including Calloway Chiropractic & Wellness, choose it.
What 'traditional' chiropractic usually means
Traditional manual adjusting, often called diversified technique, uses the doctor's hands to deliver a high-velocity, low-amplitude (HVLA) thrust to a specific joint. The familiar 'crack' is the sound of a cavitation, gas releasing from the joint fluid, and is not in itself the goal. Manual technique is effective, well studied, and remains the backbone of the profession. Its emphasis is largely structural: identifying restricted or misaligned segments and moving them.
What Torque Release Technique is
TRT was developed in the 1990s by Dr. Jay Holder as a tonal technique. Rather than focusing only on where a bone sits, tonal approaches focus on the overall tone and tension of the nervous system and the spinal cord's connective coverings (the meninges). TRT uses a specific analysis to locate the primary subluxation, the segment most responsible for neurological interference, and then corrects it with a hand-held instrument.
The Integrator
The instrument TRT uses is called the Integrator. It is a precise, hand-held adjusting tool that delivers a fast, light, reproducible impulse along a specific vector. Two features distinguish it. First, it releases at a defined force threshold, so the impulse is consistent rather than variable. Second, it incorporates a slight torque and recoil in its action, intended to engage the joint and its neurology in a way a straight thrust does not. The result is a gentle correction with no twisting, popping, or cracking.
- Low force: the impulse is light enough that patients often barely feel it.
- Specific: a defined vector and contact point rather than a regional thrust.
- Reproducible: the instrument fires at a set threshold every time.
- No cavitation: there is no need for the audible pop of manual adjusting.
- Comfortable for sensitive patients, including children, older adults, and acute cases.
The neurological reasoning behind TRT
Tonal techniques are grounded in the idea that the spine functions as a sensory organ feeding the central nervous system. This aligns with the broader spinal-neuroscience model described by Heidi Haavik and others: afferent input from the joints and muscles of the spine flows into the brain, is integrated centrally in regions including the prefrontal cortex, and shapes motor and autonomic output. A precise, low-force correction is intended to normalize that afferent input and reduce the central 'noise' created by a poorly moving segment.
The technique is designed to address the tone of the nervous system rather than to simply reposition a bone, with the correction guided by neurological indicators.
What the research actually shows
TRT is best known for a randomized, placebo-controlled clinical trial published by Holder and colleagues in 2001, conducted in a residential addiction-treatment setting. Patients receiving real Torque Release adjustments showed significantly improved retention and reduced anxiety and depression scores compared with sham-adjusted and control groups. It remains one of the more rigorous trials of a specific chiropractic technique and is frequently cited as evidence that the nervous-system effects of a precise adjustment are measurable.
It is important to be honest about scope. That study examined retention and psychological measures in a specific population; it does not establish chiropractic as a treatment for addiction or for any disease. The credible framing is consistent: TRT aims to reduce nervous-system interference and support the body's own regulatory capacity, which can have wide-ranging downstream effects, not to cure conditions directly.
How to choose between them
- Manual HVLA is well established, fast, and effective for many mechanical complaints.
- TRT is a strong fit for patients who prefer no twisting or popping, who are sensitive or in acute pain, or who are very young or older.
- Many doctors use both, matching the method to the patient and the presentation.
- The best approach is the one delivered with precise analysis and clear clinical reasoning.
At Calloway Chiropractic & Wellness, Dr. Calloway pairs Torque Release Technique with upper cervical specific analysis so that corrections are both gentle and highly targeted. The shared goal of every approach is the same: restore normal motion and clear communication between the brain and body, then let the body do what it is designed to do.
