Instrument-Assisted
Soft Tissue Mobilization

Target fascial restrictions, restore fluid movement, and move with greater confidence.

At Catalyst, tool assisted massage—also called IASTM—is used as part of an individualized plan to help address restricted motion, pain, flexibility, and strength.

What Is Tool Assisted Massage?

Tool Assisted Massage is an Instrument-Assisted Soft Tissue Mobilization (IASTM) technique used to release fascial restrictions within the body. It can help identify restrictions in the musculoskeletal system that may alter normal mechanics.

Fascia is the biological fabric that holds the body together. It weaves around muscles, nerves, ligaments, tendons, bones, arteries, veins, and organs to provide support and help transfer force. When this webbing becomes bound up or forms thick tissue masses, it can limit range of motion, alter biomechanics, and contribute to pain.

At Catalyst, we describe fascia like a sponge: when it is dry, it can feel brittle and stiff. IASTM can help break down adhesions and restore fluid channels that support springy resiliency, full muscle function, and force distribution as you move through life.

How IASTM May Support Your Recovery

IASTM is used to help release restricted motion and support a more complete rehabilitation, performance, or recovery plan.

Improve Mobility

IASTM helps increase range of motion and muscle flexibility when fascial restrictions are limiting how comfortably you move.

Support Strength

By addressing restricted tissue, this technique may support muscle function and strength as part of your exercise and rehabilitation program.

Release Restricted Motion

Tool assisted work can help release pain associated with restricted motion and may be used before or after exercise, post-operation, or alongside an athlete’s program.

Conditions & Concerns We Commonly Address

IASTM may be incorporated into care for a broad range of soft-tissue, orthopedic, repetitive stress, and post-operative concerns. Your provider will determine whether it fits your needs and goals.

  • Tendinopathies
  • Golfer’s elbow and tennis elbow
  • Patellofemoral pain syndrome
  • IT band syndrome (“runner’s knee”)
  • Myofascial dysfunction
  • Plantar fasciitis
  • Lower back stiffness
  • Shin splints
  • Temporomandibular pain
  • Soft-tissue entrapment
  • Carpal tunnel
  • Nerve pain and headaches
  • Thoracic outlet syndrome
  • Piriformis syndrome
  • Ligament or joint injury
  • Meniscus tearing
  • ACL/PCL and MCL/LCL sprains
  • Ankle sprains
  • Scar-tissue buildup
  • Post-operative care and repetitive stress injuries

What to Expect at Catalyst

Your practitioner will tailor the technique, pressure, and session length to your injury, goals, and preferences for bodywork.

Does It Hurt?

The tools are not intended to be more painful than hands. Different techniques and pressures can be used, and your practitioner will match the approach to your injury type and bodywork preference.

Session Length

Sessions are typically 30 minutes and may be shortened to 15 minutes when the area being addressed does not require the full duration. Multiple areas can be accommodated by adjusting session length.

Results & Bruising

Some people notice results after one session, while longer-lasting benefits are often experienced over 4–6 sessions depending on the issue. Redness or bruising can occur, but bruising and pain are not required for the technique to be effective.
