Metal instruments. Controlled pressure. A specific clinical reason to use them. IASTM earns its place in a treatment plan when tissue assessment points to scar tissue, fascial restriction, or adhesions that hands-on work alone won't resolve as efficiently.
Before the name: here's the mechanism. When soft tissue is injured — through trauma, surgery, or repetitive strain — the body lays down collagen to repair it. That repair tissue isn't always organized the way healthy tissue is. It can be dense, layered in the wrong direction, and resistant to normal movement. That's scar tissue and fascial adhesion. It's not a character flaw. It's biology.
Instrument-Assisted Soft Tissue Mobilization (IASTM) uses contoured stainless steel tools to apply controlled, targeted pressure to restricted tissue. The instruments amplify the clinician's ability to detect and treat these areas — the beveled edges transmit feedback through the tool that's difficult to feel with a flat palm. The controlled mechanical load triggers a local inflammatory response, which sounds counterintuitive until you understand that controlled microtrauma initiates tissue remodeling. The body responds by breaking down disorganized collagen and replacing it with better-aligned tissue.
That's the mechanism. IASTM is the label for the category of treatment that uses instruments to deliver it. Graston Technique is one branded system within that category — more on that below.
At Physica Medica, IASTM is performed by a doctoral-level physical therapist, not a technician or aide. The instruments are one tool in a broader manual therapy approach. They get used when tissue assessment indicates them — not as a default add-on.
IASTM is most effective when restricted or disorganized soft tissue is a primary driver of your symptoms. It's not the right tool for every problem, and we'll tell you that directly if it isn't.
Following rotator cuff repair, ACL reconstruction, abdominal surgery, or joint replacement, fascial planes can become restricted and movement patterns compensatory. IASTM addresses the tissue directly while manual therapy and movement work restore function.
Patellar tendon, Achilles, rotator cuff, and lateral elbow tendons that haven't responded to stretching or standard PT. Disorganized collagen at the tendon is often the structural issue — IASTM targets it specifically.
The IT band doesn't stretch — it's a thick fascial structure. IASTM addresses the fascial adhesions and tissue restrictions that contribute to lateral knee and hip pain, particularly in runners.
Chronic plantar fascia restriction that hasn't resolved with orthotics or stretching. IASTM applied to the plantar fascia and calf complex can reduce tissue density and improve load tolerance.
Layered soft tissue restriction in the neck and lower back — particularly following prolonged immobility, prior injury, or failed prior treatment — often responds well to instrument-assisted work combined with manual therapy.
Acute inflammation, active infection, open wounds, fractures, and certain vascular conditions are contraindications. IASTM also isn't the primary tool for nerve-driven pain, instability, or motor control problems — those require a different approach entirely.
The difference between IASTM done well and IASTM done indiscriminately is clinical judgment. Some clinics apply instruments to every patient as a standard protocol. That's not how we work.
Your DPT assesses the tissue before any instrument touches it — identifying restriction, density, and fascial tension through manual palpation. IASTM is selected when the assessment points to it, not because it's on a service menu.
IASTM is rarely the only treatment in a session. After instrument work, the now-responsive tissue gets manual therapy and immediate movement loading — because remodeling happens in response to load, not just mechanical stimulus. The combination is more effective than instruments alone.
If you're post-surgical, we coordinate with your surgeon or orthopedic physician. If you're managing a complex injury, IASTM may be one component alongside dry needling, deep tissue work, or fascial chain restoration — depending on what the assessment shows.
You see the same doctoral-level physical therapist each visit. No rotating staff. No handoff to an aide for instrument work while the PT moves to another patient. The person assessing your tissue is the person treating it.
Sore after? Mild soreness for 24–48 hours is normal, similar to a hard workout. Bruising is uncommon but possible at deeper insertion sites. We give every patient specific aftercare guidance based on the regions treated.
Fair question. The honest answer is: the evidence base is solid for specific conditions, and more limited for others. IASTM has peer-reviewed support for chronic tendinopathy, post-surgical soft tissue restriction, and fascial adhesion — the conditions where tissue remodeling is the actual goal. It's not a universal treatment, and the research doesn't claim it is.
The most common question before a first session is whether it hurts. Direct answer: instrument work creates a specific sensation — pressure, warmth, and sometimes mild discomfort at areas of restriction. It shouldn't be sharp or unbearable. Your therapist adjusts pressure based on your feedback and tissue response throughout.
Mild soreness for 24 to 48 hours after treatment is normal. Some patients see light bruising at areas of significant restriction — this is a known response to instrument work, not a sign that something went wrong. It resolves quickly. Most patients can continue normal activity the same day, though we'll give you specific guidance based on what was treated.

Is IASTM the same as Graston Technique? Graston Technique is a branded, trademarked system of IASTM — one of several. It uses a specific set of instruments and a proprietary training certification. IASTM is the broader category. At Physica Medica, we use IASTM instruments as part of a comprehensive manual therapy approach. The clinical principles are the same; the brand name is not what determines quality. The training and judgment of the clinician does.
Does IASTM hurt? Instrument work produces a distinct sensation — pressure and localized discomfort at restricted tissue. Most patients describe it as intense but tolerable, and notably different from the diffuse ache of chronic restriction. Your therapist works within your tolerance and adjusts throughout the session. Mild soreness and occasional bruising in the 24 to 48 hours after treatment are normal responses.
Physica Medica is located at 800 S Bond Street in Fells Point, accessible from Canton, Harbor East, and Federal Hill. IASTM is available as part of one-on-one physical therapy sessions — not as a standalone spa service. Every session is with the same doctoral-level physical therapist who assessed you.
If you've been through PT before and it didn't resolve the problem, the issue is often tissue that wasn't addressed directly. IASTM, when indicated, gets into the restriction that stretching and exercise alone don't reach. That's the clinical case for it — not a sales pitch.
Coverage varies by plan. Some plans cover it as part of standard physical therapy CPT codes; others explicitly exclude it. We verify your benefits in advance and tell you what to expect before your first session. No surprise bills. Most patients pay $145–$220 per session out of pocket, with partial reimbursement common on plans with out-of-network PT benefits. We accept HSA and FSA. Call 443-228-8029 and we'll check your specific plan.
Clear contraindications: active infection at the proposed insertion site, an active bleeding disorder, and severe needle phobia. Relative contraindications that require discussion include anticoagulant therapy (warfarin, certain DOACs), pregnancy in specific regions, lymphedema in the treated limb, and certain immunocompromised states. We screen every patient before the first needling session. If dry needling isn't appropriate for your case, we'll tell you. There are usually other manual therapy options that fit.
Same needle, different framework. Dry needling is a Western neuromuscular technique targeting trigger points identified through clinical examination, with the goal of resetting muscle dysfunction. Acupuncture is a Traditional Chinese Medicine practice targeting meridian points within an energetic framework. Both can be valuable for the right person, addressing overlapping problems with different reasoning. Dry needling at Physica Medica is performed by physical therapists, integrated into a PT plan, and measured against functional outcomes.
Most patients see meaningful change within 3–6 sessions, with maintenance visits as needed for chronic or recurrent presentations. Acute trigger-point cases sometimes resolve in 1–2 sessions. Complex chronic cases involving multiple regions and movement compensations typically require 8–12 visits to durably consolidate. We tell you our honest estimate after the initial assessment and re-evaluate at the four-week mark.
The most common reason "PT didn't work" is one of three things: too-short sessions, rotating providers, or protocol-driven exercise without hands-on diagnosis. Fellowship-trained manual therapy with dry needling integrated into a 45–60 minute one-on-one session is a different intervention. We'll tell you honestly within the first session whether we think we can help your case. If not, we'll point you to the right resource.
