Instrument-Assisted Soft Tissue Mobilization
IASTM Therapy in Baltimore
A stainless steel instrument applied with clinical precision to break down scar tissue, release fascial restriction, and retrain how your soft tissue responds to load. Performed by Dr. Maks Birikov, DPT — one patient per session, every time.
The Definition
What Is IASTM and How Does It Work?
IASTM stands for Instrument-Assisted Soft Tissue Mobilization. The technique uses specially contoured metal instruments to apply controlled mechanical force to soft tissue — muscle, fascia, tendon, and ligament. That force does something specific at the cellular level: it stimulates fibroblast proliferation, the process by which the body produces new collagen. In tissue that has been injured, restricted, or surgically altered, existing collagen is often laid down in disorganized patterns that restrict movement and perpetuate pain. IASTM disrupts that disorganized matrix and initiates remodeling.
The neurological effect matters equally. Chronic pain frequently involves central sensitization — the nervous system amplifying pain signals beyond what the tissue damage warrants. The mechanical input from IASTM instruments stimulates mechanoreceptors in the skin and fascia, which competes with and desensitizes those pain signals. This is not a theory. It is a documented mechanism, the same gate-control principle that explains why rubbing a bruised shin reduces the pain sensation.
In plain terms: the instrument reaches tissue layers that hands alone cannot effectively mobilize, generates a therapeutic inflammatory response that prompts repair, and simultaneously reduces the neurological hypersensitivity that keeps chronic pain cycling.
The Evidence
The Science Behind Instrument-Assisted Soft Tissue Mobilization
Skepticism about IASTM is reasonable. Manual therapy has a history of techniques marketed ahead of the evidence. IASTM is not one of them. Peer-reviewed research supports its application for tendinopathy, fascial adhesion, post-surgical scar tissue, and chronic musculoskeletal pain. The mechanisms — fibroblast activation, collagen remodeling, neurological desensitization — are measurable, not theoretical.
What separates effective IASTM from ineffective application is clinical reasoning. The instrument is a tool. The outcome depends entirely on the provider's ability to identify which tissue is restricted, why it became restricted, and what load progression follows the mobilization. Applied without that diagnostic framework, it is an expensive scraping session. Applied within one, it addresses the mechanical source of pain directly.
Dr. Birikov holds a Doctor of Physical Therapy degree and has trained in manual therapy techniques across three continents. IASTM at Physica Medica is not a standalone add-on — it is integrated into a full clinical assessment and treatment plan.
Applications
What IASTM Treats — Conditions and Use Cases
IASTM is appropriate across a wide range of soft tissue conditions. The common thread is restricted, fibrotic, or sensitized tissue that has not responded to conventional approaches.
Scar Tissue and Post-Surgical Restriction
Post-surgical adhesions and injury-related scar tissue are among the most direct applications. IASTM breaks down the fibrotic cross-links that limit range of motion and cause chronic tightness after surgery or significant soft tissue trauma. See the scar tissue mobilization page for condition-specific detail.
ViewTendinopathy
Chronic tendon pain — Achilles, patellar, rotator cuff, lateral elbow — often involves degenerative collagen changes rather than acute inflammation. IASTM restimulates the repair process in tissue that has stalled in a dysfunctional state.
ViewIT Band and Fascial Restriction
Dense fascial structures like the IT band respond poorly to stretching alone. Instrument-assisted mobilization reaches the depth and applies the shear force needed to alter fascial density and reduce friction-related pain.
ViewChronic Neck and Back Pain
Paraspinal and cervical soft tissue restrictions that perpetuate neck pain, tension headaches, and back pain — particularly when those tissues have been chronically overloaded by poor posture or compensatory movement patterns.
ViewPlantar Fasciitis and Foot Pain
The plantar fascia and intrinsic foot muscles respond well to IASTM when combined with progressive loading. This is more effective than stretching protocols alone for chronic cases.
ViewRecurring Sports Injuries
Hamstring strains, ankle sprains, and shoulder injuries that keep recurring often involve residual fascial restriction from prior incomplete healing. IASTM addresses that restriction before it causes the next injury.
ViewChronic Pain After Failed Treatment
Pain that has not responded to prior therapy — reassessed from the mechanism up.

IASTM vs. Graston Technique: Understanding the Difference
Graston Technique is a brand. IASTM is the broader clinical category. Graston is one proprietary system within that category — a specific set of instruments and a licensed protocol developed and trademarked by a company. Searching for 'Graston Technique Baltimore' and searching for 'IASTM Baltimore' are searches for the same underlying treatment approach.
The distinction that actually matters is not which branded system a provider uses — it is whether the provider applies instrument-assisted mobilization within a diagnostic framework or as a scripted protocol. A branded Graston certification does not guarantee clinical reasoning. A DPT with advanced manual therapy training applying IASTM instruments is not constrained by a brand's protocol.
At Physica Medica, instrument selection and application are determined by what the assessment reveals — tissue quality, restriction depth, neurological sensitivity, and how the area responds in real time. The instrument is chosen for the job. The job is defined by the diagnosis.
Plan for sixty minutes. Frequency depends on the condition. Most patients start weekly, and we taper as your body holds the changes. You will know within three to five sessions whether the approach is working, and I will tell you honestly if it isn't.
Your Session
What to Expect During an IASTM Session
Frequently Asked Questions
The session begins with assessment, not treatment. I palpate the target tissue, assess range of motion, and identify the specific structures involved before an instrument touches your skin. You will typically be positioned to place the target tissue on mild stretch — this increases the effectiveness of the mechanical input. The instrument is applied with a lubricant to reduce friction. Pressure is firm but calibrated. You will feel the instrument working through tissue layers, and in areas of significant restriction, you may feel a grating or catching sensation — that is the instrument detecting fibrotic tissue. I adjust depth and pressure based on your feedback and tissue response throughout. Redness is expected. It is a normal vascular response to mechanical stimulation, not bruising. Temporary marks are common, particularly in areas of dense restriction. They typically resolve within 24 to 72 hours. Mild soreness in the treated area for one to two days after the session is also normal and indicates the tissue responded. IASTM is almost always combined with targeted movement or loading exercises immediately following mobilization. The window after treatment is when the tissue is most receptive to remodeling — movement during that window reinforces the collagen reorganization the instruments initiated.
