Scraping / Instrument Assisted Soft Tissue Massage (IASTM).
What Is Scraping? (IASTM / Gua Sha Explained)
Scraping — also known as IASTM (Instrument Assisted Soft Tissue Mobilisation) or Gua Sha — is a form of deep tissue massage performed with a specialised instrument rather than the hands. The technique has roots in ancient Chinese medicine and is now widely used in modern physiotherapy to treat muscle tightness, restricted movement, and soft tissue pain.
How Does IASTM Work?
IASTM works on the same principle as traditional deep tissue massage: releasing tight, restricted tissue so it can move freely again. The key difference is the tool. A specialised instrument lets your physiotherapist cover more surface area and apply more targeted pressure than hands alone, producing a deeper, more effective response in the tissue causing your pain.
The instruments come in different shapes — large, blunt, and fine — with each creating a different sensation and effect. This lets us tailor the treatment to your specific injury, condition, and comfort on the day.
What Conditions Can Scraping Help With?
IASTM is commonly used to treat muscle tightness and knots, restricted range of motion, scar tissue and adhesions, chronic tendon pain, and general soft tissue injuries. It’s often combined with other hands-on treatments and a rehabilitation program for faster, longer-lasting results.
The Tools We Use
At Results Based Physio, we use professional-grade Thysol and Fasciq IASTM tools to deliver precise, effective treatment.
Frequently Asked Questions
Is scraping the same as Gua Sha?
They share the same origin and principle. Gua Sha is the traditional Chinese practice; IASTM is the modern, evidence-informed version used in physiotherapy clinics today.
Does IASTM hurt?
Most people feel firm pressure and mild discomfort rather than pain. Your physiotherapist adjusts the intensity to suit you, and any redness afterward typically settles within a day or two.
How many sessions will I need?
It depends on your condition. We’ll give you a clear, upfront treatment plan at your first visit so you know exactly what to expect.
The IASTM Tools We Use
IASTM instruments come in a range of shapes and edges — large, blunt, and fine — with each one creating a different sensation and effect on the tissue. This variety lets your physiotherapist tailor the treatment to your specific injury and comfort level.
Using an instrument rather than the hands allows us to cover more surface area and apply more targeted, controlled pressure, producing a deeper and more effective deep tissue response. It’s a precise way to release tight muscles, break down restricted tissue, and get you moving freely again.
At Results Based Physio, we use professional-grade Thysol and Fasciq IASTM tools to deliver safe, effective, results-driven treatment.
