Instrument-Assisted Soft Tissue Mobilization (IASTM)

Instrument-assisted soft tissue mobilization in Eugene, Oregon for scar tissue, adhesions, tendinitis, and chronic restriction.

Scar tissue doesn’t show up on an X-ray. It still limits how you move.

AFTER A COLLISION

What IASTM Is

A skilled intervention for muscle, tendon, and fascia — the tissue that contracts to move you, the tissue that anchors muscle to bone, and the thin mesh that separates and connects every muscle in the body. Instruments vary, but the most common is stainless steel with a beveled edge.

DELAYED SYMPTOMS

How the Technique Works

The instrument’s shape lets the clinician locate a restriction, then treat it with the appropriate pressure. It creates controlled microtrauma in the tissue, which breaks up the adhesions and scar tissue left by an old injury, surgery, immobilization, or repeated strain.

That microtrauma starts the body’s own healing response, which remodels or absorbs the adhesion.

Call (541) 343-3477 with a question before your visit.

I started seeing Dr Sontag chiropracter at Aspen several months ago. They started taking Kaiser Permenante. He listened to my complaints & adjusted me. One time my right shoulder & neck were very sore from moving & I was fortunate to find an appointment the day I called. After adjustment I was back to normal! One time I did receive a bill that was lengthy so I talked to the billing lady who explained things & even didn't charge me for 1 item which Kaiser didn't pay saying they'd take the loss. My co-pays are susually between $25-35. I heard the massage therapist there is quite good, from a friend of mind who used his services. Pro: Friendly & professional staff, Dr. Sontage is quick & efficient, doesn't require x-rays, free parking, online appoint. Cons: none that I can think of

Came in not able to move my neck, my collarbone was throbbing all day long and my hips ached all night. After one visit my hips and collarbone were pain free and I was sleeping through the night. After two visits my neck was moving without pain.

I had been appreciating my fortnightly chiropractic adjustment at Aspen chiropractic for several months And left a separate ***** review for Jeremy Sontag, and also, the***** Also applies to the premises, which are very pleasant and clean with a lot of healthy looking plants despite being on a busy street there are trees and it’s very pleasant. NOW, I would like to leave my review for massage therapy. I just saw him for the third time. I am impressed by his competence and knowledge of the body. Every week the massage has been quite different. He is responsive to areas that I tell him are causing me problems. For example, I came in with a headache today and I said do you think you can get rid of it, and sure enough he did he is trained and experienced in complete full body massage every area of the body. You’re not only response to my requests, but he is intuitive and seems to know exactly what to do. He definitely earned five stars.

Dr Joshua Anderson hands down is the best chiropractor I have ever had ( and I've had a few in the past). I had a brain injury several years ago. This caused a reversed cervical with compression on nerves with the damage in my neck, nerve damage through face etc, compression, jaw issues, occipital neuralgia attacks frequently with times of excruciating pain that was debilitating. I had to stop hiking and doing many things I loved. My quality of life was not good and depressing. Then Dr Anderson at Aspen chiropractic was highly recommended to me. He was so kind, gentle, understanding, and knowledgeable with many different techniques. He understood my fears after all I had been through with the head injury. Also, that I wanted to be able to live my life again (even though I have permanent structural damage). Dr Anderson has been successfully managing my permanent stabilized condition. I am functionally able to hike and live life again through his continued care. I am grateful to him for giving me back my life. The whole staff at Aspen Chiropractic is wonderful. This is the place and it's the best!! Aspen Chiropractic in west Eugene (305 w 7th) is the place to go.
