Tight, stubborn tissue
It targets the ropey, restricted spots that keep an area from moving freely, the ones that do not release with stretching alone.

Soft Tissue Mobilization
A hands-on technique your clinician uses during care at EVO. A specialized tool glides over tight, stubborn tissue to calm pain and free up how you move. You may know it as Graston.
What it actually does
A tool that finds what hands can’t
Instrument-assisted soft tissue mobilization, or IASTM, uses a smooth-edged stainless steel tool to glide across skin and muscle. The edge picks up on tight, ropey, or restricted areas your clinician can feel through the instrument, and lets them work those spots with more precision and control than hands alone.
If you have heard of Graston, this is the same family of technique, and Graston is its best-known brand. At EVO we use HawkGrips instruments, another professional IASTM system, applied by a clinician who is HawkGrips-certified in the technique.
What IASTM helps with
Scar tissue and old injuries
It is often used on tissue that healed stiff or restricted after a strain, surgery, or an injury that never fully let go.
Range of motion
By freeing up restricted tissue, it can help an area move through more of its natural range.
Pain that lingers
For some nagging, chronic tissue pain, it is a useful way to change the input and calm things down.
What a session feels like
Firm, focused, and quick
Your clinician applies a lubricant, then moves the tool over the target area in specific strokes for a short time, usually a few minutes per spot. It should feel firm, sometimes a little intense over a tight area, but not something you have to grit through. Tell your clinician if it is too much and they adjust.
You may see some redness or, occasionally, light bruising afterward. That fades in a few days and is not a measure of how well it worked. IASTM is almost always paired with movement, the stretching and strengthening that turn a freed-up area into a lasting change.

Why it is never the whole plan
A tool can free up tissue, but it cannot teach your body to hold the change. That is what the active work is for. We use IASTM to open a door, then load the area so it stays open. On its own it is a short-term reset. Paired with the right exercise, it becomes progress.
How it fits at EVO
A tool, in trained hands
IASTM is not a machine you sit at, it is a technique applied by a clinician who knows when it helps and when it does not. At EVO it is used inside your physical therapy or chiropractic care, chosen when your assessment shows a tissue restriction is part of what is holding you back.
[PROVIDER] is a HawkGrips Certified Practitioner in IASTM, which matters, because the tool is only as good as the hands and the judgment behind it. We reach for it when it fits the plan, not by default.
The research
An honest read on the evidence
IASTM has real support for specific uses, and like most hands-on tools, it works best as one piece of a bigger plan. Here is the honest picture.
A systematic review of 13 controlled trials found IASTM improved range of motion in healthy people and improved pain and day-to-day function in injured patients, while calling for more high-quality research to confirm how far the benefits generalize.

That fits how we use it: strong enough to be worth reaching for when a tissue restriction is in the way, not a stand-alone cure. The tool opens the door, the active work is what walks you through it.
