Active Release Technique (ART) is a patented, hands-on soft tissue treatment designed to break up scar tissue and adhesions in muscles, tendons, ligaments, connective tissue, and nerves. Often described as a “movement-based massage,” it combines precise manual pressure from a practitioner with specific movements performed by the patient. Most people notice improvement after the first session, and a full course of treatment typically ranges from one to six visits.
How ART Works
When soft tissues are overused or injured, the body lays down scar tissue as part of the healing process. In small amounts, this is normal. But when scar tissue accumulates, it creates adhesions: sticky patches where layers of muscle, fascia, or nerve tissue bind together. These adhesions shorten and weaken muscles, restrict range of motion, and can trap nerves. Reduced blood flow to the area (sometimes called tissue hypoxia) compounds the problem, slowing recovery and perpetuating pain.
ART targets these adhesions directly. The practitioner uses their hands to feel the texture, tightness, and movement quality of the tissue, then applies precisely directed tension to the problem area while you actively move the affected muscle through a specific range of motion. That combination of external pressure and active movement creates a shearing force that separates adhesions from the surrounding muscle fibers, restoring normal glide between tissue layers.
This is a key distinction from passive treatments. You aren’t lying still while someone works on you. Your movement is an essential part of the technique, and it’s what allows the practitioner to isolate and release specific structures that other approaches might miss.
What ART Treats
ART was developed by P. Michael Leahy, a chiropractor who noticed that many of his patients’ symptoms correlated with changes in soft tissue he could detect by hand. By refining his approach over years of clinical work, he reported resolving over 90% of his patients’ soft tissue complaints. The technique addresses three broad categories of injury:
- Acute injuries: muscle pulls, tears, spasms, and contractures from a single event.
- Repetitive strain injuries: accumulated micro-tears from doing the same motion over and over, common in desk workers, athletes, and tradespeople.
- Nerve entrapment: compressed or trapped nerves caused by surrounding scar tissue buildup, which can cause tingling, numbness, or radiating pain.
In practice, this covers conditions like tennis elbow, lower back pain, hip snapping syndromes, tendon inflammation, and posterior shin pain in runners. A systematic review in the Journal of Sport Rehabilitation found that six studies assessing pain after ART treatment all showed significant improvements, and six studies looking at range of motion found significant gains as well.
What a Session Feels Like
Sessions are short, typically lasting about 15 minutes. The practitioner will first assess the area by pressing into the tissue with their hands, identifying spots where the texture feels dense, ropy, or restricted. Once they locate the adhesion, they’ll pin it with firm thumb or finger pressure and ask you to move the joint through a prescribed range of motion. You might bend your elbow, rotate your shoulder, or flex your foot, depending on the area being treated.
The pressure can feel intense, especially over areas with significant adhesion buildup. Some people describe it as a deep, productive discomfort rather than sharp pain. Mild soreness afterward is common and usually resolves within a day or two. Because the sessions are brief and targeted, they fit easily into a lunch break or pre-workout routine.
How ART Differs From Other Techniques
The easiest way to understand ART is to compare it to what it’s not. In a standard deep tissue massage, you’re typically passive while the therapist applies sustained pressure to relax muscles and improve circulation. Massage works on broad areas and is excellent for general tension, but it isn’t specifically designed to locate and break individual adhesions.
The Graston Technique, another popular option, uses specially designed stainless steel instruments to scan and scrape the tissue. The tools create a controlled micro-trauma that triggers an inflammatory response, restarting the healing process. During Graston, you’re usually relaxed and still while the practitioner moves the instruments over your skin. ART, by contrast, uses hands only and requires your active participation. Another notable difference: ART is considered highly effective for nerve entrapment, while instrument-based techniques primarily target fascia and muscle tissue.
Who Performs ART
ART is a patented system with its own credentialing process. Practitioners, who are typically chiropractors, physical therapists, or sports medicine providers, must complete hands-on seminars and pass practical exams. There are two certification levels: Level 1 builds a foundation in soft tissue treatment protocols, and Level 2 covers more advanced techniques. Certifications must be renewed regularly to ensure providers stay current. When looking for a practitioner, you can verify their active certification through the official ART website.
How Many Sessions You’ll Need
Many people feel a noticeable difference after a single session, particularly in range of motion. For more chronic or layered problems, a full treatment course ranges up to six sessions. The exact number depends on how long the issue has been present, how much scar tissue has accumulated, and whether the underlying cause (a repetitive motion at work, a training error, poor posture) is also being addressed. ART is often combined with rehabilitation exercises and other therapies to prevent the adhesions from returning.
