Pediatric Massage Study Finds Surprising Results

By Tracy Walton, LMT, MS

I had the great pleasure of attending the American Massage Therapy Association National Convention in Minneapolis this year, and hearing a panel discuss pediatric massage research. Among the presenters was Dr. Sean Phipps, a psychologist and researcher at St. Jude Children's Research Hospital in Memphis.

He presented a large study of massage and humor therapy in children undergoing stem cell transplant (SCT).1 Stem cell transplant is typically used to treat certain types of cancer and blood diseases. It is a rigorous procedure, with multiple medical risks to the patient.

This is an important and useful study for a number of reasons:

  1. It was a large study of 178 pediatric patients, in four locations across the U.S. and Canada.

  2. It was a randomized, controlled trial, designed to high standards in clinical research.

  3. The study reported that massage had no effect on any of the outcomes studied. Not one.

I'll leave the explanation and importance of the first two points to the various resources in massage research literacy.2 Instead, I want to focus here on the last point, that the study observed NO effect from massage or humor therapy in pediatric SCT patients. The audience was understandably surprised, and some of us were stunned. What happened?

Background

Because stem cell transplant is notoriously strong treatment, associated with high degrees of distress for patients and families, the study looked at both patient- and parent-targeted interventions. This was not the first time the group attempted research in this area; Previous, smaller studies had documented the feasibility and appeal of massage and humor therapy,3 and had even suggested some benefit to warrant this further study, which was a larger scale, NIH-funded controlled trial.

The patients, aged 6-18, were randomized into three arms. One was a child-targeted intervention composed of massage and humor therapy. Another group received the child-targeted intervention in addition to a parent-targeted intervention that involved massage and relaxation/imagery. The third group, the control group, received only standard medical care.

A standard massage routine was provided by professional massage therapists, with the intended dose set at three half-hour sessions per week for 4 weeks, beginning at 1 week before transplant. The actual average massage dose turned out to be 8.8 sessions over the course of the study, as timing and other logistics often affect the actual amount delivered. The researchers measured somatic distress, mood disturbance, length of hospitalization, the time to engraftment (for the transplant to "take") and the use of opioid pain relievers and antiemetics (antinausea drugs).

Findings

As stated above, the investigators found that massage therapy and humor therapy made no difference in any of the outcomes. The patients' experiences of SCT appeared to be unchanged by these two complementary therapies. Even the addition of the parent-targeted therapy, in which the designated parent received massage on the same schedule as the child, along with relaxation therapy, seemed to make no difference. In fact, Dr. Phipps showed graphs of the three groups that were almost identical. Changes in mood and distress measures did occur in all three groups over the course of 4 weeks, but they were typical ups and downs over the course of the procedure. During SCT, the mood and distress measures get worse before they get better, and the patterns were the same in all three groups.

There were no differences in the medical outcomes, either. The time to engraftment, length of hospital stay, and use of pain relievers and antiemetics were surprisingly similar across the three groups.

What Do We Make Of This?

The study authors admitted being surprised by the results, and even disappointed. One important quality in a research paper is humility, and the authors were quick to point out possible limitations in the study design: perhaps they weren't measuring exactly the right outcomes, or the timing of the measurements was not perfect. The age range of 6-18 years in their patient may have been too broad to fully standardize the treatments. They also report that the results of a single study--theirs--is not sufficient for firm conclusions. More studies, from additional researchers, are needed before we can determine whether to advise massage for this population.

In fact, levels of distress in the study sample were quite low to begin with, and throughout the study. While SCT-related distress still exists, it may be that standard medical care is already reducing it to the lowest levels possible, and massage cannot be expected to take it any further.

I was impressed by the care taken in this project, by the findings, and by the reflections of the investigator. I have a few of my own thoughts to add to discussion:

First, it is important for researchers to publish work like this, when the outcomes do not meet the researcher's hypothesis. If we reported only the "good" or "bad" news in massage research (a problem called publication bias), then it would hold back the science of massage, and take longer to learn its true impact. I hope that other massage therapy trade publications also report on these findings, as disappointing as they are, so that the news is balanced.

Second, as much as I might wish for massage to have an effect in this population, the science and my own wishful thinking are two separate things. Massage is powerful therapy, but it is unlikely to be a cure-all. If it really is true that massage has no significant effect on a given population, we need to know that. As a profession, it's important to know if massage is less effective in some populations than in others. If it is, we can direct our study and practice where we know it is effective. Perhaps other patient populations are more responsive to massage, or there are places where the medical management of a condition falls short, and massage could play a larger role. If so, perhaps we should focus our efforts there. This would not mean denying massage to people undergoing SCT. Instead, it would mean that we continue to study the impact of massage, learn where it's most effective, and make sure we act on that information.

Finally, I am interested in the massage design and dose. I have to ask, in this and other studies, whether the massage dose is sufficient to bring about a change? Do we need to schedule daily massage in some populations, so that after logistics have taken their toll, the participants end up receiving 4-5 sessions per week? If so, would 4-5 sessions per week be sufficient, or too much? Does scheduling massage at certain points compromise its effectiveness, and, instead, it should be provided on demand the way some pain medications are administered? Are certain massage strokes, or body areas of focus essential for massage to be effective?

As disappointing as these results were, the study offers an important contribution to the body of research. I am not ready to abandon massage of SCT patients, nor do the investigators suggest that we should. But the study asks good questions. I am grateful to the investigators for their care, expertise, and clear reporting. As good research, this study invites further reflection, discussion, and, of course, more research.
