Massage therapy
Pooled trials found massage eased pain more than no treatment and, by a smaller margin, more than sham and other active treatments, mostly in the short term. Three meta-analyses found less muscle soreness after exercise, while strength and sprint recovery did not change. Anxiety and depression scores fell in pooled trials. Serious harms appear only in case reports.

What it is used for, and what was found
Shown to help7
Pain across conditions
Shown to ease pain more than no treatment, by a large margin, and more than sham or active treatments, by smaller margins, in a meta-analysis of 67 trials.
Compared with sham treatments [2]; no treatment [2]; active treatments [2]
The numbers and sources
- Effect
- Massage lowered pain more than sham (SMD -0.44), no treatment (SMD -1.14) and active comparators (SMD -0.26) [2]. A map of 49 systematic reviews, 32 rated high quality, found their conclusions gave low strength of evidence for potential benefits in labor, shoulder, neck, low back, cancer, arthritis, postoperative and muscle soreness pain [3].
- Population
- 67 randomized trials of people with pain in the general population, 60 rated high quality [2]. 49 systematic reviews [3].
- Sources
- [2], [3]
- Caveats
- The evidence map notes few large, rigorous trials and poor description of the massage given, so reviews could not say which type helps which pain [3]. Participants cannot be blinded to massage.
Low back pain
Shown to ease subacute and chronic low back pain more than inactive controls in the short term, with no lasting difference. Against active treatments the pain difference was small.
Compared with inactive controls [4]; active treatments [4]; usual care [5]
The numbers and sources
- Effect
- For subacute and chronic low back pain, massage lowered pain more than inactive controls in the short term (SMD -0.75, 95% CI -0.90 to -0.60, 7 trials, 761 participants) and improved function (SMD -0.72), with no difference in the long term. Against active controls, pain was lower in the short term (SMD -0.37, 12 trials, 964 participants) and long term (SMD -0.40), and function did not differ [4]. In 401 adults, Roland disability scores at 10 weeks were 2.9 points lower with relaxation massage and 2.5 points lower with structural massage than with usual care [5].
- Population
- 25 trials with 3,096 participants, almost all with subacute or chronic low back pain [4]. 401 adults aged 20 to 65 with chronic low back pain in Seattle [5].
- Sources
- [4], [5]
- Caveats
- The reviewers rated the evidence low to very low and wrote that they have very little confidence in massage for low back pain [4]. The trial did not blind participants to massage versus usual care [5].
Knee osteoarthritis
One trial of 222 adults found weekly massage improved knee osteoarthritis scores more than light touch or usual care at 8 weeks, with no difference at 52 weeks.
Compared with light touch [7]; usual care [7]
The numbers and sources
- Effect
- At 8 weeks, WOMAC global scores improved by 8.16 points more than light touch (95% CI -13.50 to -2.81) and 9.55 points more than usual care (95% CI -14.66 to -4.45), with gains in pain, stiffness and function. At 52 weeks, change did not differ across groups (P = 0.707) [7].
- Population
- 222 adults with knee osteoarthritis [7].
- Sources
- [7]
- Caveats
- One trial. Light touch was the closest thing to a sham, and participants knew which hands-on treatment they had.
Muscle soreness after exercise
Shown to reduce muscle soreness 24 to 72 hours after strenuous exercise compared with no massage, in three meta-analyses.
Compared with no intervention [8]; control conditions the source abstracts do not describe [9][10]
The numbers and sources
- Effect
- Against no intervention, soreness was lower at 24 hours (SMD -0.61, 95% CI -1.17 to -0.05), 48 hours (SMD -1.51, 95% CI -2.24 to -0.77) and 72 hours (SMD -1.46, 95% CI -2.59 to -0.33) after intense exercise [8]. Across 99 studies of recovery techniques, massage had the largest effect on soreness and perceived fatigue [9]. Across 29 studies with 1,012 participants, massage was linked to small improvements in soreness and flexibility [10].
- Population
- 504 participants in 11 trials [8]. 99 studies of recovery methods [9]. 1,012 participants in 29 randomized studies [10].
- Sources
- [8], [9], [10]
- Caveats
- Soreness is self-rated and participants know they had a massage. The three reviews share many of the same small trials.
Anxiety
Shown to lower anxiety in pooled trials, including state anxiety after a single session and trait anxiety after a course of treatment.
Compared with control conditions in randomized studies the source abstract does not describe [12]; active treatments [2]
The numbers and sources
- Effect
- A meta-analysis of 37 randomized studies found single sessions reduced state anxiety, and a course of treatment reduced trait anxiety and depression, its largest effects, by amounts the authors likened to psychotherapy [12]. Against active comparators in pain populations, anxiety was lower with massage (SMD -0.57) [2].
- Population
- 37 randomized studies [12]. Trials in people with pain [2].
- Sources
- [12], [2]
- Caveats
- The older meta-analysis predates many current trials and its abstract gives no effect sizes [12]. Participants cannot be blinded to massage.
Depression
Shown to lower depressive symptoms against control groups in a meta-analysis of 17 trials, with a moderate pooled effect.
Compared with control groups the source abstract does not describe [15]
The numbers and sources
- Effect
- Across 17 randomized trials, the pooled standardized mean difference was 0.73 (95% CI 0.52 to 0.93) in the random-effects model, favoring massage [15]. An earlier meta-analysis found reductions in depression among massage's largest effects [12].
- Population
- 786 people with depression in 17 trials, excluding infants and pregnant women [15]. 37 randomized studies [12].
- Sources
- [15], [12]
- Caveats
- Trials were of moderate quality, used different massage protocols and depression scales, and may be heterogeneous [15].
Sleep
Limited evidence: low-certainty trials in critically ill adults and cancer survivors found better self-reported sleep quality after massage.
Compared with control groups the source abstracts do not describe [16][17]
The numbers and sources
- Effect
- In critically ill adults, foot reflexology massage improved subjective sleep quality in subgroup analysis, and a two-night course helped in cardiac care patients [16]. In 4 trials in cancer survivors, massage improved self-reported sleep and accelerometer-recorded long sleep episodes [17].
- Population
- 569 participants in 10 trials in adult critical care [16]. Cancer survivors in 4 trials [17].
- Sources
- [16], [17]
- Caveats
- Overall certainty was rated low [16]. No trial in healthy adults or in people with insomnia alone was located.
Mixed results4
Neck pain
Limited evidence: very low-quality trials suggested some massage techniques improved function and tenderness more than control or placebo, and reviewers called the effect uncertain.
Compared with control or placebo treatment [6]; education [6]
The numbers and sources
- Effect
- Very low-quality evidence suggested traditional Chinese massage and strain-counterstrain techniques may improve function and tenderness more than control or placebo, and massage may ease pain bothersomeness more than education in the short term. Most trials measured outcomes immediately after treatment [6].
- Population
- 15 trials of adults with mechanical neck disorders [6].
- Sources
- [6]
- Caveats
- All trials were rated low or very low in quality, and only 4 of 15 described the massage adequately. The reviewers made no recommendation [6].
Strength, sprint and performance recovery
Mixed results: one meta-analysis found no effect on strength, jump, sprint or endurance, while others found small gains in force or short-term performance recovery.
Compared with no intervention [8]; control conditions the source abstracts do not describe [10][11]
The numbers and sources
- Effect
- Across 29 studies, massage did not improve strength, jump, sprint, endurance or fatigue [10]. In another pooled analysis, maximal isometric force (SMD 0.56) and peak torque (SMD 0.38) were higher after massage [8]. Across 22 trials, performance recovery effects were small: +6.6% with 5 to 12 minutes of massage and +1.0% with more than 12 minutes, larger for recovery periods of up to 10 minutes (+7.9%) than more than 20 minutes (+2.4%) [11].
- Population
- 1,012 participants in 29 studies [10]. 504 participants in 11 trials [8]. 22 randomized trials [11].
- Sources
- [10], [8], [11]
- Caveats
- The authors of [11] called the effects rather small and partly unclear, larger in untrained people than in trained athletes.
Generalized anxiety disorder
Small trials disagree: one found Swedish massage lowered anxiety more than light touch, and another found massage did not differ from a relaxing room or heat therapy.
Compared with light touch [13]; thermotherapy [14]; a relaxing room [14]
The numbers and sources
- Effect
- In 47 untreated adults with generalized anxiety disorder, twice-weekly Swedish massage for 6 weeks lowered Hamilton Anxiety scores by 11.67 points against 8.41 with light touch (difference 3.26, P = .030) [13]. In 68 adults with the disorder, massage, thermotherapy and a relaxing room all lowered anxiety scores by 10 to 13 points, with no difference between groups (P = .39), and gains held at 26 weeks [14].
- Population
- 47 adults, 40 analyzed [13]. 68 adults [14].
- Sources
- [13], [14]
- Caveats
- Two small trials. The authors of [14] attributed the improvement in every group to a general relaxation response.
Stress hormones, blood pressure and immune cells after one session
Mixed results: a single session lowered blood pressure and heart rate in pooled trials, and cortisol fell in one small trial but not in pooled trials.
Compared with control conditions in randomized studies the source abstract does not describe [12]; light touch [18]
The numbers and sources
- Effect
- Single sessions reduced state anxiety, blood pressure and heart rate, and did not reduce cortisol [12]. In healthy adults, 45 minutes of Swedish massage produced a large drop in arginine vasopressin and a small drop in blood cortisol against light touch. Circulating lymphocytes rose (effect sizes 0.14 to 0.43) and stimulated cytokine production fell [18].
- Population
- 37 randomized studies [12]. Healthy adults aged 18 to 45 [18].
- Sources
- [12], [18]
- Caveats
- The trial calls its data preliminary, and these were changes over one session [18]. Lymphocyte counts in blood do not show fewer infections.
Protocols studied
Massage in the trials was mostly given by hand, and 3 low back pain trials used a mechanical device [4]. The back pain trial compared structural and relaxation massage [5]. The knee osteoarthritis trial gave 60 minutes of full-body massage weekly for 8 weeks, then every other week to 52 weeks [7]. The generalized anxiety trials used Swedish massage twice a week for 6 weeks [13] and 10 sessions over 12 weeks [14]. The hormone and immune study used one 45-minute session [18].
After exercise, the soreness trials used massage after strenuous or high-intensity exercise [8][9]. In the performance analysis, sessions of 5 to 12 minutes showed larger effects than sessions longer than 12 minutes [11].
Risks
Reported risks3
More pain or soreness after treatment
Shown in trials as the most common side effect, with increased pain reported in 1.5% to 25% of participants across back pain trials.
The numbers and sources
- How common
- How often is not known: the sources give no rate.
- Effect
- In low back pain trials, increased pain intensity was the most common adverse event, in 1.5% to 25% of participants [4]. In neck pain trials, the 4 that reported side effects all reported pain after treatment, and one found low blood pressure after treatment in 22% of participants [6].
- Population
- 25 low back pain trials [4]. 15 neck pain trials, 4 reporting side effects [6].
- Sources
- [4], [6]
- Caveats
- The range spans two frequency bands and no pooled rate was given. Most trials did not report side effects [6].
Serious injuries in case reports
Case reports: 138 adverse events in 40 reports from 2003 to 2013, including disc herniation, nerve injury and vertebral artery dissection, often linked to spinal manipulation within massage.
The numbers and sources
- How common
- How often is not known: the sources give no rate.
- Effect
- From 2003 to 2013, 40 reports described 138 adverse events with massage, mainly disc herniation, soft tissue trauma, neurologic compromise, spinal cord injury and vertebral artery dissection. Spinal manipulation within massage was repeatedly tied to the serious events [19]. An earlier review of 16 case reports and 4 case series found most harms followed exotic techniques or massage by laypeople, rarely massage therapists. Reported events included stroke, nerve damage, pulmonary embolism and hematoma [20].
- Population
- 138 cases [19]. 16 case reports and 4 case series [20].
- Sources
- [19], [20]
- Caveats
- Case reports give no rate. Both reviews judged serious events rare [19][20].
Bowel twisting after abdominal massage in premature infants
Case reports: 17 cases of volvulus in premature infants after abdominal massage, 4 of them fatal, in a review of 60 pediatric massage studies.
The numbers and sources
- How common
- How often is not known: the sources give no rate.
- Effect
- Of 60 studies of massage in children, 16 reported at least one adverse event. There were 20 mild, 26 moderate and 18 severe events. Of the severe events, 17 were volvulus in premature infants given abdominal massage, and 4 were fatal [21].
- Population
- Children aged 0 to 18 in 60 studies [21].
- Sources
- [21]
- Caveats
- The reviewers say it is not yet defined whether the link is causal, and 31 of the 60 studies gave no adverse event information [21].
Checked, no increase found1
Serious adverse events in trials
No serious adverse events were reported in 25 trials of massage for low back pain.
The numbers and sources
- How common
- How often is not known: the sources give no rate.
- Effect
- There were no reports of serious adverse events in any of the 25 trials [4]. In the knee osteoarthritis trial, adverse events were described as minimal [7].
- Population
- 3,096 participants in 25 trials [4]. 222 adults [7].
- Sources
- [4], [7]
- Caveats
- Trials are too small to detect rare events, and many did not report adverse events at all.
Claims tested and not found
- That massage speeds removal of lactic acid from muscle after exercise. In 12 people, forearm blood flow and lactate removal after strenuous handgrip exercise were lower with massage than with passive rest [22].
- That sports massage improves strength, sprint or jump performance. Pooled data from 29 studies found no improvement in strength, jump, sprint, endurance or fatigue [10].
- That massage beats other relaxation treatments for generalized anxiety disorder. Anxiety fell by similar amounts with massage, heat therapy and a relaxing room [14].
