Is Your Tissue Stiff, Scarred, or "Stuck" No Matter How Much You Stretch?
IASTM, or instrument-assisted soft tissue mobilization, uses specialized handheld tools to find and break up the scar tissue and adhesions that build up in muscles, tendons, and fascia. At Adair Chiropractic in North Liberty, IA, we use IASTM alongside Active Release Technique to treat the restricted, gritty, or "stuck" tissue that stretching and foam rolling can't reach on their own.
If you've been told your muscles are "tight" and it never seems to change no matter how much you stretch, roll, or ice, the issue usually isn't flexibility. It's scar tissue that's built up in the fibers of the muscle itself, and that requires a tool that can actually find and release it.
When Stretching and Rolling Aren't Enough, Here's Why
You've done everything you're supposed to do. You stretch before and after activity. You foam roll. Maybe you've tried a massage gun or a percussion device at home. And for an hour or two, it feels a little better. Then the tightness comes right back, in the exact same spot, like nothing happened.
That's frustrating, and it's also a clue. Surface-level tools like foam rollers and massage guns work on the muscle belly, but they can't get specific enough to find small pockets of scar tissue or adhesions between layers of tissue. When soft tissue heals from an old injury, overuse, or repetitive strain, it doesn't always heal in neat, organized fibers. It can heal in a tangled, fibrous mess that restricts movement and blood flow, and that tangle is what keeps producing the same tightness in the same place, over and over.
The tightness isn't the problem. It's the symptom of tissue underneath that hasn't fully healed.
What Is IASTM, and Who Does It Help?
Instrument-assisted soft tissue mobilization is a manual therapy technique that uses stainless steel or specially shaped tools to apply controlled pressure across the skin and into the underlying muscle and fascia. The tool's edge acts almost like a detection device: it catches on areas of scar tissue, adhesions, and fibrous restrictions that a practitioner's hands often can't feel as precisely, and that pressure helps break the tissue down so the body can remodel it properly.
You may see IASTM referred to by other names. Graston technique is a specific branded version of the same concept, and "muscle scraping" is a common, more casual term for the general approach. The tools and certifications differ slightly, but the underlying goal across all of them is the same: locate restricted tissue and mechanically encourage it to release.
IASTM tends to help people with:
Chronic muscle tightness that doesn't respond to stretching: The kind of tightness that comes back within hours of a massage or stretching session, in the same spot, week after week.
Old injuries that never fully resolved: Sprains, strains, or overuse injuries from months or years ago that left behind scar tissue, even after the original pain went away.
Tendinopathies: Conditions like tennis elbow, golfer's elbow, Achilles tendinopathy, and plantar fasciitis, where thickened, disorganized tendon tissue is part of what's keeping the pain going.
Restricted range of motion: Shoulders, hips, or necks that feel "tight" in a specific direction, often tied to fascia that's adhered to the tissue underneath it.
Post-surgical or post-injury scar tissue: Scarring around a healed injury site or incision that limits movement or creates a pulling sensation.
If your tissue feels gritty, ropy, or restricted in a specific spot rather than generally sore, IASTM is usually a good fit. If you're dealing with an acute injury, active inflammation, or a skin condition in the treatment area, we'll assess first and adjust the approach.
Meet Your IASTM Provider: Dr. Karla Adair, D.C.
18+ years of Active Release Technique and soft tissue expertise in The Corridor
Dr. Karla K. Adair, D.C. is the owner of Adair Chiropractic and has practiced in North Liberty since graduating with honors from Palmer College of Chiropractic in 2006. She holds a B.S. in Biology with a business minor from Wartburg College, where she also competed in softball at the national level. Dr. Adair has been certified in Active Release Technique since 2006, giving her 18+ years of hands-on experience treating soft tissue and nerve entrapment conditions, making her one of the longest-tenured ART providers in The Corridor.
IASTM is one of several manual therapy tools Dr. Adair uses alongside ART, therapeutic exercise, and laser therapy to treat the root cause of restricted, scarred, or adhered tissue rather than just the symptoms.
For nearly two decades, Dr. Adair has helped patients throughout North Liberty, Coralville, and Iowa City get back to the activities they care about, without relying on rest and bracing alone.

What Changes When Scar Tissue Actually Releases
When restricted tissue is addressed rather than just managed, the changes are noticeable fast:
- The same spot stops being the same spot. Tightness that used to return within hours starts staying away for days, then weeks.
- Range of motion opens up in the direction that used to feel stuck, whether that's reaching overhead, rotating your neck, or bending a knee fully.
- Old injuries stop nagging. Areas that have felt "off" since an injury years ago start to feel normal again.
- You need less maintenance. Instead of daily rolling and stretching just to feel functional, your tissue holds its improvements.
- Athletic performance and daily movement both improve, because tissue that glides properly transfers force more efficiently and is less prone to re-injury.
Most of the patients who come to us for IASTM have already tried rest, rolling, and regular massage. It works for them because it targets what those approaches can't fix: scar tissue that's already formed and needs a mechanical nudge to reorganize.
Frequently Asked Questions
They're closely related. Graston technique is a specific, branded system of IASTM using patented stainless steel tools, while IASTM is the broader category of instrument-assisted soft tissue work. The goal and the general method are the same: use a tool to find and release restricted tissue.
Most people feel pressure and, over restricted areas, a distinct catching or scraping sensation rather than sharp pain. Mild redness is common right after treatment, and some patients develop light bruising over more restricted areas, which typically fades within a few days and isn't a sign anything went wrong.
It depends on how long the restriction has been there and how much scar tissue has built up. Many patients notice improved mobility within 2 to 4 sessions, while long-standing or post-surgical scar tissue can take longer. We'll give you a realistic estimate after your first assessment.
IASTM is safe for most people when performed by a trained provider. We use caution or avoid the technique over active infections, open wounds, recent fractures, blood clotting disorders, or certain skin conditions. We'll screen for these during your intake.
Yes, and it often is. Many patients get their best results when IASTM addresses localized scar tissue in the same visit that ART addresses broader muscle and nerve restrictions, or that an adjustment addresses joint alignment. This is also common for patients dealing with tennis elbow or golfer's elbow, where tendon and nerve restrictions often overlap. Dr. Adair builds each visit around what your tissue actually needs that day.
