What IASTM is
IASTM uses smooth stainless-steel tools with rounded edges. I put a little lotion on the skin and glide the tool along the muscle, tendon or fascia with short or long strokes. The metal passes over the tissue easily, and through it I can feel areas that are thicker, grainy or less mobile than the tissue around them.
The aim is to help those restricted areas move more freely and to encourage blood flow. As with many manual techniques, the scientific evidence is still mixed, but in practice many active people find it useful, especially for areas that do not respond well to hands alone.
How it feels
Most people describe it as a scraping or rubbing sensation, sometimes with a slightly warm feeling afterwards. Over a restricted spot it can feel more intense or “crunchy”. It should not be sharp. I start lightly and adjust the angle and pressure to what you tell me.
What it can help with
- Scar tissue and old injuries, once they are fully healed, where the area feels tight or stuck
- Fascial restrictions, for example along the outer thigh, the calves or the forearms
- Tendons that get overloaded, such as the Achilles tendon in runners or the elbow and forearm in strength training
- Small areas that are hard to reach precisely with the hands
How I use it in a session
IASTM is part of a sport massage and is not booked on its own. I usually warm the area with my hands first, use the tool for a few minutes, and then finish with massage, myofascial release or stretching. For runners it often goes on the calves and shins.
Aftercare
- Expect some redness for a few hours; it is a normal reaction
- Move gently afterwards, a walk or easy mobility is ideal
- Leave hard training on that area for the rest of the day if it feels tender
Who should avoid it
I will not use the tool, or will use it only very lightly, if you have:
- bruises, open wounds, a fresh scar or irritated skin in the area
- varicose veins
- blood thinners or a tendency to bruise easily
- a recent injury, swelling or an area that is hot and inflamed
- a condition that affects your skin or blood vessels
If you are not sure whether IASTM is right for you, tell me when you arrive and we will decide together.
