A novel clinical-trial design for the study of massage therapy

Massage Therapy May be Safe and Reduce Pain in Critically Ill Patients with Acute Neurological Injury: a Case Control Study

Purpose

Massage therapy is an important adjunctive treatment for physiologic and psychologic symptoms and has been shown to benefit patients among a wide variety of patient populations.

Setting

Few studies have investigated the utility of massage therapy in the general ICU setting, and even fewer have done so in the neurological ICU (NeuroICU).

Research Design

If massage therapy was determined to improve objective outcomes-or even subjective outcomes in the absence of harm-massage may be more readily employed as a complementary therapy, particularly in the ICU setting or in patients with acute neurological injury.

Intervention

This pilot study aimed to assess the safety of massage in the neurocritical care unit and its impact on patient vital signs, subjective pain assessment, and other clinical outcomes.

Participants

Twenty-one patients who received massage therapy during admission to the neurocritical care service were compared to matched controls in a retrospective case control study design.

Results

We found a statistically significant reduction in pain scores among patients with acute neurological injury who received massage therapy. There was no statistical difference in hospital length of stay, discharge destination, in-hospital mortality, adverse events, or incidence/duration of delirium between patients who received massage therapy and those who did not. No adverse events were ascribed to the massage therapy when evaluated by blinded neurocritical care specialists.

Conclusion

This study found that massage therapy may be safe for many patients in the NeuroICU and may offer additional subjective benefits.

The Trials and Tribulations of Selecting Comparison Groups in Randomized Trials of Nonpharmacological Complementary and Integrative Health Interventions

Editor's Note: For over two decades, JACM Editorial Board member Karen Sherman, PhD has been among the most respected clinical trialists in complementary and integrative health research. The epidemiologist and Senior Researcher at Kaiser Permanente Washington Health Research Institute has focused on pain conditions and has led or been part of teams exploring the roles of such therapies as yoga, acupuncture, mind-body and manual therapies. In this Invited Commentary, Sherman shares wisdom gleaned from the process: trial designs, principles for selecting controls, benefits and liabilities of placebo and sham controls, attention controls, usual care controls, and more. She also discusses the effects of comparison groups on sample sizes, comparison groups for mechanistic studies, and other comparison groups' considerations. This commentary should prove a useful primer wherever research methods in complementary and integrative health are taught.

Changing Author Guidelines to Include Patient and Public Involvement

Multiple benefits have been found when patients and the public are included as research co-investigators. To this end, a change is being made to the IJTMB authorship guidelines to include a new subsection within the Methods section of manuscripts, entitled "Patient and Public Involvement". We recommend that authors include in this section information on how patients and other stakeholders were included in the design, implementation, data analysis, and dissemination of studies. Further guidelines are provided.

Efficacy and Safety of Massage for Osteoarthritis of the Knee: a Randomized Clinical Trial

BACKGROUND

Current treatment options for knee osteoarthritis have limited effectiveness and potentially adverse side effects. Massage may offer a safe and effective complement to the management of knee osteoarthritis.

OBJECTIVE

Examine effects of whole-body massage on knee osteoarthritis, compared to active control (light-touch) and usual care.

DESIGN

Multisite RCT assessing the efficacy of massage compared to light-touch and usual care in adults with knee osteoarthritis, with assessments at baseline and weeks 8, 16, 24, 36, and 52. Subjects in massage or light-touch groups received eight weekly treatments, then were randomized to biweekly intervention or usual care to week 52. The original usual care group continued to week 24. Analysis was performed on an intention-to-treat basis.

PARTICIPANTS

Five hundred fifty-one screened for eligibility, 222 adults with knee osteoarthritis enrolled, 200 completed 8-week assessments, and 175 completed 52-week assessments.

INTERVENTION

Sixty minutes of protocolized full-body massage or light-touch.

MAIN MEASURES

Primary: Western Ontario and McMaster Universities Arthritis Index. Secondary: visual analog pain scale, PROMIS Pain Interference, knee range of motion, and timed 50-ft walk.

KEY RESULTS

At 8 weeks, massage significantly improved WOMAC Global scores compared to light-touch (- 8.16, 95% CI = - 13.50 to - 2.81) and usual care (- 9.55, 95% CI = - 14.66 to - 4.45). Additionally, massage improved pain, stiffness, and physical function WOMAC subscale scores compared to light-touch (p < 0.001; p = 0.04; p = 0.02, respectively) and usual care (p < 0.001; p = 0.002; p = 0.002; respectively). At 52 weeks, the omnibus test of any group difference in the change in WOMAC Global from baseline to 52 weeks was not significant (p = 0.707, df = 3), indicating no significant difference in change across groups. Adverse events were minimal.

CONCLUSIONS

Efficacy of symptom relief and safety of weekly massage make it an attractive short-term treatment option for knee osteoarthritis. Longer-term biweekly dose maintained improvement, but did not provide additional benefit beyond usual care post 8-week treatment.

Rhythmical massage improves autonomic nervous system function: a single-blind randomised controlled trial

BACKGROUND

Rhythmical massage therapy (RMT) is a massage technique used in anthroposophic medicine.

OBJECTIVE

The authors aimed to investigate the physiological action of RMT on the cardiovascular system by analysing heart rate variability (HRV).

DESIGN, SETTING, PARTICIPANTS AND INTERVENTION

This study was a randomised, controlled and single-blinded trial, involving 44 healthy women (mean age: (26.20 ± 4.71) years). The subjects were randomised to one of three arms: RMT with aromatic oil (RA), RMT without aromatic oil (RM) or standardised sham massage (SM). In the study the subjects were exposed to a standardised stress situation followed by one of the study techniques and Holter electrocardiograms (ECGs) were recorded for 24 h.

MAIN OUTCOME MEASURES

HRV parameters were calculated from linear (time and frequency domain) and nonlinear dynamics (symbolic dynamics, Poincare plot analysis) of the 24-h Holter ECG records.

RESULTS

Short- and long-term effects of massage on autonomic regulation differed significantly among the three groups. Immediately after an RMT session, stimulation of HRV was found in the groups RA and RM. The use of an aromatic oil produced greater short-term measurable changes in HRV compared with rhythmic massage alone, but after 24 h the effect was no longer distinguishable from the RM group. The lowest stimulation of HRV parameters was measured in the SM group.

CONCLUSION

RMT causes specific and marked stimulation of the autonomic nervous system. Use of a medicinal aromatic oil had only a temporary effect on HRV, indicating that the RM causes the most relevant long-term effect. The effect is relatively specific, as the physiological effects seen in the group of subjects who received only SM were considerably less pronounced.

Perceptions of Massage Therapists Participating in a Randomized Controlled Trial

Background

Clinical practice and randomized trials often have disparate aims, despite involving similar interventions. Attitudes and expectancies of practitioners influence patient outcomes, and there is growing emphasis on optimizing provider–patient relationships. In this study, we evaluated the experiences of licensed massage therapists involved in a randomized controlled clinical trial using qualitative methodology.

Methods

Seven massage therapists who were interventionists in a randomized controlled trial participated in structured interviews approximately 30 minutes in length. Interviews focused on their experiences and perceptions regarding aspects of the clinical trial, as well as recommendations for future trials. Transcribed interviews were analyzed for emergent topics and themes using standard qualitative methods.

Results

Six themes emerged. Therapists discussed 1) promoting the profession of massage therapy through research, 2) mixed views on using standardized protocols, 3) challenges of sham interventions, 4) participant response to the sham intervention, 5) views on scheduling and compensation, and 6) unanticipated benefits of participating in research.

Conclusions

Therapists largely appreciated the opportunity to promote massage through research. They demonstrated insight and understanding of the rationale for a clinical trial adhering to a standardized protocol. Evaluating the experiences and ideas of complementary and alternative medicine practitioners provides valuable insight that is relevant for the implementation and design of randomized trials.

Massage therapy and exercise therapy in patients with multiple sclerosis: a randomized controlled pilot study

OBJECTIVE

The primary aim was to investigate the comparative effects of massage therapy and exercise therapy on patients with multiple sclerosis. The secondary aim was to investigate whether combination of both massage and exercise has an additive effect.

DESIGN

Randomized controlled pilot trial with repeated measurements and blinded assessments.

SETTING

Local Multiple Sclerosis Society.

SUBJECTS

A total of 48 patients with multiple sclerosis were randomly assigned to four equal subgroups labelled as massage therapy, exercise therapy, combined massage-exercise therapy and control group.

INTERVENTIONS

The treatment group received 15 sessions of supervised intervention for five weeks. The massage therapy group received a standard Swedish massage. The exercise therapy group was given a combined set of strength, stretch, endurance and balance exercises. Patients in the massage-exercise therapy received a combined set of massage and exercise treatments. Patients in the control group were asked to continue their standard medical care.

MAIN MEASURES

Pain, fatigue, spasticity, balance, gait and quality of life were assessed before and after intervention.

RESULTS

Massage therapy resulted in significantly larger improvement in pain reduction (mean change 2.75 points, P = 0.001), dynamic balance (mean change, 3.69 seconds, P = 0.009) and walking speed (mean change, 7.84 seconds, P = 0.007) than exercise therapy. Patients involved in the combined massage-exercise therapy showed significantly larger improvement in pain reduction than those in the exercise therapy (mean change, 1.67 points, P = 0.001).

CONCLUSIONS

Massage therapy could be more effective than exercise therapy. Moreover, the combination of massage and exercise therapy may be a little more effective than exercise therapy alone.

Open-label, randomized, parallel-group controlled clinical trial of massage for treatment of depression in HIV-infected subjects

OBJECTIVES

The study objectives were to determine whether massage therapy reduces symptoms of depression in subjects with human immunodeficiency virus (HIV) disease.

DESIGN

Subjects were randomized non-blinded into one of three parallel groups to receive Swedish massage or to one of two control groups, touch or no intervention for eight weeks.

SETTINGS/LOCATION

The study was conducted at the Department of Psychiatry and Behavioral Neurosciences at Cedars-Sinai Medical Center in Los Angeles, California, which provided primary clinical care in an institutional setting.

SUBJECTS

Study inclusion required being at least 16 years of age, HIV-seropositive, with a diagnosis of major depressive disorder. Subjects had to be on a stable neuropsychiatric, analgesic, and antiretroviral regimen for >30 days with no plans to modify therapy for the duration of the study. Approximately 40% of the subjects were currently taking antidepressants. All subjects were medically stable. Fifty-four (54) subjects were randomized, 50 completed at least 1 week (intent-to-treat; ITT), and 37 completed the study (completers).

INTERVENTIONS

Swedish massage and touch subjects visited the massage therapist for 1 hour twice per week. The touch group had a massage therapist place both hands on the subject with slight pressure, but no massage, in a uniform distribution in the same pattern used for the massage subjects.

OUTCOME MEASURES

The primary outcome measure was the Hamilton Rating Scale for Depression score, with the secondary outcome measure being the Beck Depression Inventory.

RESULTS

For both the ITT and completers analyses, massage significantly reduced the severity of depression beginning at week 4 (p ≤ 0.04) and continuing at weeks 6 (p ≤ 0.03) and 8 (p ≤ 0.005) compared to no intervention and/or touch.

CONCLUSIONS

The results indicate that massage therapy can reduce symptoms of depression in subjects with HIV disease. The durability of the response, optimal "dose" of massage, and mechanisms by which massage exerts its antidepressant effects remain to be determined.

Development of a manualized protocol of massage therapy for clinical trials in osteoarthritis

BACKGROUND

Clinical trial design of manual therapies may be especially challenging as techniques are often individualized and practitioner-dependent. This paper describes our methods in creating a standardized Swedish massage protocol tailored to subjects with osteoarthritis of the knee while respectful of the individualized nature of massage therapy, as well as implementation of this protocol in two randomized clinical trials.

METHODS

The manualization process involved a collaborative process between methodologic and clinical experts, with the explicit goals of creating a reproducible semi-structured protocol for massage therapy, while allowing some latitude for therapists' clinical judgment and maintaining consistency with a prior pilot study.

RESULTS

The manualized protocol addressed identical specified body regions with distinct 30- and 60-min protocols, using standard Swedish strokes. Each protocol specifies the time allocated to each body region. The manualized 30- and 60-min protocols were implemented in a dual-site 24-week randomized dose-finding trial in patients with osteoarthritis of the knee, and is currently being implemented in a three-site 52-week efficacy trial of manualized Swedish massage therapy. In the dose-finding study, therapists adhered to the protocols and significant treatment effects were demonstrated.

CONCLUSIONS

The massage protocol was manualized, using standard techniques, and made flexible for individual practitioner and subject needs. The protocol has been applied in two randomized clinical trials. This manualized Swedish massage protocol has real-world utility and can be readily utilized both in the research and clinical settings.

Perceptions and use of complementary and alternative medicine in American Samoa: a survey of health care providers

PURPOSE

American Samoa health care providers' use and perceptions of common complementary and alternative treatments, with a focus on traditional Samoan healing for women diagnosed with breast cancer or cervical cancer, was investigated to inform the development of the first locally produced women's cancer prevention radio drama and the first cancer patient navigator program in the US Territory.

METHODS

A 10-item self-administered survey was completed by a total of 47 health care providers employed at the Lyndon B. Johnson Tropical Medical Center and the American Samoa Department of Health Breast and Cervical Cancer Early Detection Program.

FINDINGS

Comprehensive health care is limited in American Samoa, especially cancer treatment. Dissatisfaction or disconnection with Western medicine leads some patients to seek complementary or alternative health care from traditional Samoan healers who provide massage and herbal remedies. Health care providers in American Samoa use and recommend many complementary and alternative medicines (CAM) popular in the United States. The most common CAM recommended to patients is exercise (81%), diet modification (81%), prayer (36%), massage (36%), support group participation (26%), and relaxation techniques (19%). Traditional Samoan healing methods are unique CAM that 19% of mainstream health care providers have used, and 17% have recommended these techniques to patients. Most survey respondents believe traditional Samoan healing methods have a harmful effect on patient quality of life and 72% have advised a patient to discontinue using this type of CAM. While most providers feel that the majority of American Samoan patients use traditional healing methods to complement Western healthcare, 55% are aware of a breast cancer or cervical cancer patient utilizing these techniques as an alternative to hospital treatment. A provider's ethnicity, gender, age and years of professional experience appear to be indicators of different CAM method endorsement and patient consultations concerning CAM use.

CONCLUSIONS

CAM use is likely to continue in American Samoa as long as health care deficiencies exist. Most American Samoa health care professionals accept common CAM in the United States, but local providers are more likely to endorse traditional healing methods than their mainland counterparts. Little is known of the impact different CAM have on quality of life, especially amongst cancer patients. The majority of American Samoa health care providers request more information about tradition al healing which would facilitate more comprehensive medical documentation and patient care.

The culture of massage therapy: valued elements and the role of comfort, contact, connection and caring

OBJECTIVE

To explore the attributes of the therapy encounter valued by repeat users of health-related massage therapy.

DESIGN

A qualitative design with telephone focus group methodology was used. A total of 19 repeat users of massage therapy participated in three telephone focus groups where audiotaped semi-structured interviews were conducted.

SETTING

Telephone focus group with massage clients from a range of provincial and urban regions in New Zealand.

MAIN OUTCOME MEASURES

Summary of reported themes of the massage experience. Data were thematically analysed using the general inductive approach.

RESULTS

Six valued elements of the massage encounter (time for care and personal attention, engaging and competent therapist, trust partnership, holism and empowerment, effective touch and enhancing relaxation), four modulators (comfort, contact, connection and caring) and two themes relating to adding experiential value (enjoyment, escapism) characterize the massage therapy culture.

CONCLUSIONS

The culture of massage therapy care incorporates a number of characteristics that are congruent with the complementary and alternative medicine approach to health. In addition, massage specific factors were identified. The humanistic aspects of the therapy encounter valued by clients offer insight into the growing use of massage therapy and the success of massage therapy outcomes.
