Deep Tissue Massage

Massage in orthodox medicine

A 2000 historical review in a nursing and midwifery journal says writers on massage usually refer to its long history in ancient cultures but stop with Ling, to whom they attribute the development of modern massage in the early 19th century. The author argues that late 19th and early 20th century literature shows massage to have been an orthodox medical therapy practiced by doctors and nurses, in forms that differ from most of today's practice despite similar terminology.

The same review says massage almost disappeared as an orthodox therapy after World War II and has recently re-emerged as a complementary therapy. A 2003 systematic review of harms likewise describes massage therapy as experiencing a revival after many years out of the limelight. Neither source discusses deep tissue massage by name.

Where the label comes from

The sources reviewed for this page do not establish who first used the label deep tissue massage or when. A 2017 narrative review reports that the literature has no commonly accepted definition and credits the method, as a specific and independent form of massage, to a set of principles and techniques defined by Riggs. The phrase was in clinical use by 1999, when a case report of liver hematoma after deep tissue massage appeared in a medical journal, but that date shows only that the term was in use and says nothing about when the practice began.

Deep massage and deep tissue massage

The 2017 narrative review found that the definition used most often in published studies is the intention of the therapist. Its authors propose that deep massage should describe an intention to reach deep tissue with any form of massage, while deep tissue massage should name a specific method with its own principles and techniques. Because trials use the words differently, results labeled deep tissue massage may describe different treatments.

The review also notes that variation in techniques and protocols across studies has made clear conclusions difficult, and it calls for future research to use a common definition. Until that happens, a claim about deep tissue massage should be checked against how the term was used in the study behind it.

How trial authors and health agencies describe it

A Polish trial paper describes the method as work with the layers of the body to relax, lengthen and release persisting tension, and says therapists aim to change soft-tissue structure by acting on the muscle belly and the tendon-to-bone attachment until tissue responds. This is the authors' description of the technique and its proposed purpose, and it is not a measured mechanism.

The US National Center for Complementary and Integrative Health (NCCIH) lists Swedish or classical, sports and clinical massage as common styles and refers to deep tissue massage as one of the more vigorous styles. Its page does not define deep tissue massage separately.

Setting and practitioner

In the Polish trial, patients were referred to an outpatient rehabilitation clinic and the massage was given by certified therapists who did not know which group a patient belonged to. The sources reviewed do not describe other settings in detail. NCCIH advises people to ask a therapist about training, experience and credentials, and about the number of treatments likely to be needed, the cost and insurance coverage.

Technique as described in the literature

The Riggs definition quoted in both the narrative review and the trial paper says the therapist works with tissue in layers within the client's parameters of comfort. The trial authors add that muscles are placed in a lengthened position and the therapist acts on the tissue gradually until it responds with relaxation. Pressure and technique are therefore described as adjustable, and a person can discuss comfort and ask for a change in pressure or for a pause.

Session schedules used in studies

Study schedules vary. The Polish low back pain trial used a 30-minute session each day for two weeks, ten sessions in all. A pilot study in men with ankylosing spondylitis also gave ten sessions. A 2025 trial in athletes reported 40-minute sessions twice weekly for eight weeks. These are research protocols, not standard practice, and the sources reviewed describe no agreed session length or number.

Uses described in the literature

The 2017 narrative review suggests that favorable outcomes may result from deep tissue massage in people with pain and in people with decreased range of motion, while stressing that the evidence is limited by inconsistent methods. The Polish trial paper describes the method as often used for musculoskeletal pain, and the athlete trial frames it as a means of muscle recovery and performance improvement.

Conditions in which it has been studied

Controlled studies reviewed here concern chronic low back pain, subacute or persistent neck pain, lower back pain in ankylosing spondylitis, and recovery and flexibility in athletes. NCCIH's general massage page reports weak evidence for low back pain and possible short-term benefit for neck and shoulder pain, and describes the evidence for most uses of massage as limited. Claims beyond these conditions were not supported by sources opened for this page.

Low back pain

A 2014 randomized trial of 59 adults with chronic low back pain compared two weeks of deep tissue massage with the same massage plus a nonsteroidal anti-inflammatory drug. Pain and disability scores improved in both groups and did not differ between them. Because there was no group without massage, the trial cannot show how much of the improvement was due to the massage rather than time or expectation. Measures were taken one day after treatment ended, so longer-term effects are unknown.

A 2015 Cochrane review of massage generally for non-specific low back pain included 25 trials with 3,096 participants. It found short-term pain relief compared with inactive controls for sub-acute and chronic pain, but not in the long term, and judged the quality of the evidence low to very low. The review's authors said they had very little confidence that massage is an effective treatment. The review did not isolate deep tissue massage, so its conclusions should not be transferred to this style without caution.

Neck pain: the Stockholm Neck trial

The Stockholm Neck (STONE) trial randomized 619 adults with subacute or persistent neck pain to deep tissue massage (145), supervised strengthening and stretching exercises (160), a combination (169) or advice to stay active (147). Massage was associated with more people reporting improved pain intensity than advice at seven weeks (relative risk 1.36, 95% confidence interval 1.04 to 1.77), but not at later follow-ups. At 12 months none of the treatments was more effective than advice for pain intensity or pain-related disability.

A cost-effectiveness analysis of the same trial found that massage and the combined therapy were more costly and less beneficial than advice. Quality-adjusted life-year scores were close across groups, averaging 0.88 for massage and 0.88 for advice.

Other populations

A pilot trial of 27 men with ankylosing spondylitis compared deep tissue massage with a gentler therapeutic massage over ten sessions. Groups did not differ on most outcomes, with differences reported only for disease activity and low back pain intensity, and the authors called for further research. A 2025 trial of 150 athletes reported better recovery and flexibility with massage, but its abstract does not describe a comparison group, so a reviewer should check what the improvements were measured against.

What remains uncertain

No systematic review specific to deep tissue massage was found among the sources opened for this page; PubMed searches were run on the exact phrase, on safety of massage, and on massage for low back pain. Trials differ in definition, dose, comparator and follow-up, and most outcomes are self-reported. Evidence in one condition cannot be applied to another, and none of the sources reviewed tested whether the proposed tissue-level effects occur.

Harms in trials and reviews

The Cochrane review of massage for low back pain reported no serious adverse events in its trials; increased pain was the most common adverse event, reported by 1.5% to 25% of participants. A 2003 systematic review found 16 case reports and four case series of adverse effects from massage of many types, including hematoma, nerve damage, cerebrovascular events and pulmonary embolism. Its author concluded that massage is not entirely risk free but that serious events are probably rare, and noted that serious effects were mostly linked to techniques other than Swedish massage.

The 2017 narrative review of deep tissue massage reported several rare serious adverse events, probably related to forceful application. NCCIH likewise says serious events such as blood clots, nerve injury and bone fractures are rare and mostly involved vigorous styles such as deep tissue massage, or higher-risk people such as older adults.

Case reports after deep tissue massage

Case reports include liver hematoma (1999) and a large buttock hematoma (2015); only the titles and bibliographic records of these two were available to the reviewer. A 2025 report describes a woman in her 50s with a nonocclusive internal jugular vein thrombosis the day after a painful neck massage, treated with an anticoagulant, with the clot resolved at three months. The authors state that the mechanism is unclear.

A 2023 report describes a 47-year-old underweight woman with C5 and C6 nerve root injury after a three-minute massage of the anterior scalene muscle in the neck, with recovery of strength over six months. The authors advise caution in this area, especially in underweight people. Case reports show that an event followed massage, and they do not give its frequency.

Suitability and care boundaries

NCCIH advises discussing concerns with a health care provider before starting and warns against using massage in place of seeing a provider about a medical problem. The sources reviewed do not list formal contraindications for deep tissue massage and do not address bleeding disorders or anticoagulant use. Sudden severe pain, swelling, new weakness, numbness or other neurological symptoms after a session are reasons to seek prompt medical assessment.

On training, NCCIH notes that some US therapists hold national certification that requires education, a background check and an exam. The sources reviewed describe no training standard specific to deep tissue massage and no professional-body register for it. Information about requirements elsewhere was not found.
