PulStar multi-impulse adjusting in Marietta
An adjustment with no twist and no pop.
An adjustment without twisting, cracking or sudden movement. A handheld instrument taps each spinal segment, measures how much it resists, and treats what it finds.
Tapping, measuring, then treating
The PulStar is a handheld instrument with a spring-loaded head connected to a computer. Placed against a spinal segment, it delivers a rapid series of very light taps and records how much each segment resists the same force. Stiffer segments return a higher reading, and the result is drawn on screen as a bar chart of your spine before treatment begins. The same instrument then delivers a gentle, repeated impulse to the restricted segments, and the scan is repeated afterward so you can see the comparison.
The mechanism is different from a manual adjustment. Instead of one larger thrust taking a joint to the end of its range, the instrument uses many small, fast impulses that stay well inside your comfort range. There is no rotation of the neck, no torsion of the low back, and no cavitation sound. For people whose apprehension about chiropractic is specifically about being twisted, that difference is the whole point.
What the treatment feels like and how it is used
You sit or lie face down, fully clothed, while the head of the instrument is placed on the skin. The taps feel like a light, rapid drumming. It is not painful, most people find it oddly pleasant, and nothing about it requires you to relax on command — which matters, because guarding against a manual adjustment is one reason an adjustment misses.
It is used as the primary adjusting method for patients who need a low-force approach, and as one option among several for everyone else. Common reasons to choose it: older patients with osteoporosis or degenerative change, people who are anxious about manual adjusting, children and teenagers, acute guarding where a joint cannot be taken to end range yet, and anyone who has had spinal surgery in the region.
What the evidence supports and where it does not
Mechanical-force instrument adjusting is well studied as a category and is broadly comparable to manual adjusting for spinal pain outcomes, with the practical advantages of consistent force delivery and better tolerance in low-force cases. The reproducibility argument is genuine: an instrument delivers the same force every time, which a human hand cannot.
The measurement side deserves more care. The scan records mechanical resistance at the surface, which is a useful before-and-after comparison and a good communication tool. It is not an image, it is not a diagnosis, and it does not measure nerve function or health. Any presentation of these charts as proof of what is happening in your nervous system is going further than the instrument can support.
Session structure and your typical care timeline
A visit is short — scan, treat the restricted segments, rescan. Early care usually means a cluster of visits over a few weeks while the segments hold their new motion for progressively longer, then a step down in frequency. Because each visit produces a chart, changes over the course of care are easy to look at side by side rather than relying on memory.
It is normally combined with soft-tissue work and specific exercise. An instrument can restore segmental motion; it cannot strengthen what let the segment stiffen in the first place.
Contraindications and safety notes
The force involved is low, which widens the range of people who can be treated, but it does not remove the need for examination. Fracture, bone infection, active malignancy in the spine, unexplained progressive neurological loss and unstable inflammatory arthritis all rule out adjusting of any kind until they have been worked up.
Tell us about spinal surgery and hardware, osteoporosis, blood thinners, implanted devices and pregnancy — not because these necessarily prevent treatment, but because each one changes where and how the instrument is used.

What people want to know about it
No. The impulses are small, fast and stay inside your comfortable range, so there is no cavitation sound and no twisting of the neck or low back. If avoiding that sensation is the reason you have put off care, this is the method to ask about.
For spinal pain, instrument adjusting and manual adjusting produce broadly comparable outcomes in the research. Each has strengths: an instrument delivers identical force every time and is far better tolerated in low-force cases; a skilled hand adapts in ways an instrument cannot. Many practices use both depending on the segment and the patient.
Mechanical resistance — how stiffly each segment pushed back against the same light tap, before and after treatment. It is a comparison tool, not an image or a diagnosis, and it says nothing about nerve function. It is useful precisely because you can see whether the stiff segment changed.
Low-force instrument adjusting is one of the standard choices for both, including patients with osteoporosis, degenerative change or previous spinal surgery. Examination still comes first, and the settings and contact points are chosen for the individual.
