There’s Little Evidence That Massage Therapy Helps With Pain

By Crystal Lindell

It’s often touted as an alternative pain treatment, but it turns out there’s not much evidence showing that massage therapy actually helps with either chronic or acute pain. 

That’s according to new research published in JAMA Network Open that analyzed hundreds of clinical studies of massage therapy for pain. In a systematic review of those studies, the authors found little evidence that massage therapy actually helps relieve pain. In fact, most of the studies concluded that the certainty of evidence was low or very low. 

Notably, the researchers looked at studies involving many different types of pain, including cancer-related pain, chronic and acute back pain, chronic neck pain, fibromyalgia, labor pain, myofascial pain, plantar fasciitis, postpartum pain, postoperative pain, and pain experienced during palliative care. 

“There is a large literature of original randomized clinical trials and systematic reviews of randomized clinical trials of massage therapy as a treatment for pain,” wrote lead author Selene Mak, PhD, a researcher and program manager at the VA’s Greater Los Angeles Healthcare System. 

“Our systematic review found that despite this literature, there were only a few conditions for which authors of systematic reviews concluded that there was at least moderate-certainty evidence regarding health outcomes associated with massage therapy and pain. Most reviews reported low- or very low–certainty evidence.”

The results are especially concerning because massage therapy is often recommended as an nonopioid alternative for treating pain. In fact, in its revised 2022 opioid guideline, the CDC specifically mentions “massage” multiple times as a nonpharmacologic alternative. 

“Nonopioid therapies are preferred for subacute and chronic pain. Clinicians should maximize use of nonpharmacologic and nonopioid pharmacologic therapies as appropriate for the specific condition and patient,” the guideline says.

Researchers involved in the current study found that “massage therapy” was a poorly defined category of treatment, which made it more difficult to analyze. For example, in some studies, acupressure was considered massage therapy, but at other times it was classified as acupuncture. 

“Massage therapy is a broad term that is inclusive of many styles and techniques,” Mak wrote. “This highlights a fundamental issue with examining the evidence base of massage therapy for pain when there is ambiguity in defining what is considered massage therapy.”

Researchers also found that it was difficult to do placebo-controlled massage studies because it’s difficult to compare massage with a sham or placebo treatment. 

“Unlike a pharmaceutical placebo, sham massage therapy may not be truly inactive,” they wrote. “It is conceivable that even the light touch or touch with no clear criterion used in sham massage therapy may be associated with some positive outcomes.… Limitations of sham comparators raise the question of whether sham or placebo treatment is an appropriate comparison group in massage therapy trials.”

The researchers said it might be better to compare massage therapy with other treatments rather than a placebo. They also called for more high-quality research to look into exactly how helpful massage therapy is for pain. 

All of this doesn’t mean that massage therapy offers zero benefits, and patients who get something out of it should continue to use it.  However, medical professionals (and guideline authors) should be more cautious about recommending massage as a substitute for proven pain treatments, such as opioids. Because the last thing people in pain need is to be given ineffective treatments while being denied effective ones..
