What Is IASTM (Instrument-Assisted Soft Tissue Mobilization)?

IASTM, sometimes called Graston, Astym, or Gua Sha therapy, is a hands-on treatment where your provider uses a specially designed tool (made of metal or plastic) to apply gentle pressure and scraping motions to your skin over areas of pain, tightness, or old scar tissue.

How It Helps You

Think of scar tissue or chronically tight muscle as a tangled knot of fibers that your body never quite finished repairing correctly. This treatment works by:

• Gently "waking up" the area so your body restarts its natural healing process in tissue that has gotten stuck

• Increasing blood flow to bring in fresh oxygen and nutrients needed for repair

• Breaking down old, disorganized scar tissue or adhesions that limit your movement

• Encouraging your body to rebuild that tissue in a stronger, more organized way, so it moves and functions better

• Calming overly sensitive nerve signals in the area, which can reduce your pain

What You Might Feel

During treatment, you may notice mild pressure, a scraping sensation, or occasional tenderness, especially over areas with more scar tissue or tightness. Some redness or minor bruising afterward is normal and expected, it's a sign the treatment is stimulating healing in that spot.

What to Expect Afterward

• Many patients feel improved movement or reduced tightness right after their first session

• Full benefits typically build over a series of visits, as your tissue gradually remodels and heals

• Your provider will often pair this with stretching or exercises to support lasting results

Common Reasons This Treatment Is Used

• Muscle strains or sprains

• Tendon injuries (like tennis elbow or shin splints)

• Scar tissue after surgery

• Chronic tightness or restricted movement

• Repetitive strain injuries from overuse

This is a non-invasive, drug-free option, meaning it doesn't involve needles, incisions, or medication, making it a low-risk addition to your overall recovery plan.
