Abstract
Background
Massage therapy is a popular treatment for musculoskeletal conditions globally. As the efficacy for massage therapy grows over time, it is becoming a more acceptable form of therapy alongside conventional medicine. The aim of this systematic review is to highlight the prevalence of massage therapy utilization specifically for the treatment of musculoskeletal conditions.
Methods
A comprehensive search of health databases using keywords mapped to massage and musculoskeletal conditions identified 38 studies. An assessment of the quality of these studies was undertaken using a validated quality appraisal instrument.
Results
Overall, the prevalence of massage use ranged from 2% to 81.2%. The range narrowed marginally from 2.2% to 56% in larger studies (n ≥ 1,000). Prevalence was higher among younger individuals, ranging from 12% to 56%. The prevalence of use among women ranged from 7.7% to 56%. The highest prevalence for conditions was for lower back pain/back pain, ranging from 10.5% to 68.1%, and for patients with chronic pain, ranging from 17.6% to 56%. The lowest prevalence was reported in Australia, ranging from 2% to 56%, and the highest in North America, from 2.2% to 81.2%.
Conclusions
Our findings indicate that 74% of studies in this review relating to prevalence of massage therapy utilization for musculoskeletal conditions are reported within studies focusing on complementary medicine more generally. Further studies on massage as an independent treatment modality would be useful to provide improved evidence on prevalence for massage use for musculoskeletal conditions. While the range of prevalence reported here is wide, inpatients and outpatients with specific musculoskeletal conditions including pain are high users of massage therapy. Despite the growing interest in research, there is a gap in the literature around men and their use of massage therapy. Further high-quality research in these areas will better inform the knowledge base around these participant cohorts.

INTRODUCTION
Musculoskeletal conditions include injuries that affect the musculoskeletal system arising from physiological and psychological injury as well as external and environmental factors such as sports and exercise. Generally, these conditions can be localized to one or more muscles, bones, and connective tissues and be associated with muscle tension and/or joint injury, inflammation, stiffness, or can affect a broader area depending on the level of injury. Musculoskeletal conditions may be caused by acute injury or occur more gradually over time leading to chronic injury such as osteoarthritis or degenerative injury such as rheumatoid arthritis or other more localized chronic conditions such as back pain, gout, and other disorders of the musculoskeletal system.(1)
The World Health Organization estimates that there are 1.71 billion people with musculoskeletal conditions worldwide and due to population growth and aging, the number of people living with musculoskeletal conditions and associated functional limitations is rapidly increasing.(2) Musculoskeletal conditions significantly limit mobility and dexterity, which may lead to lower levels of well-being and reduced ability to participate in society and contribute to early retirement from work. It is not surprising then that musculoskeletal conditions are the leading contributor to disability worldwide.(2)
Massage therapy is one of many complementary and integrative medicine (CIM) practices that make up a diverse group of beneficial health and wellness treatment modalities that are not traditionally associated with conventional medicine or medical curriculum.(3) As one of the more popular forms of treatment for conditions either associated with or independent of chronic pain, massage therapy has become a widely acceptable form of CIM alongside conventional practice or as a sole form of treatment.(4–14) Massage therapy has also been shown to be one of the most commonly used forms of treatment to relieve symptoms associated with musculoskeletal conditions, and by doing so, it improves mobility, reduces pain, and increases quality of life.(9,12,13,15–21) The most common reason for massage therapy utilization is for the treatment of muscle pain, joint and bone pain relief, and mood elevation.(22–25)
While data reporting on prevalence of massage therapy utilization are mostly drawn from studies investigating CIM, previous publications reporting on the prevalence of massage therapy utilization specifically have focused on patterns and predictors of massage practitioner utilization in the United States (lifetime 12.8% and previous 12 months 6.8%),(26) as well as visits to massage therapists by the general adult population (United States, UK, Canada, Australia, Singapore, and South Korea: median = 5.5%).(27) The prevalence of massage therapy use has also been reported in relation to specific non-musculoskeletal illnesses such as headache disorders (Australia: 33.9%)(28) and palliative care (US veterans: 26%).(29)
Despite massage therapy being a popular form of CIM for musculoskeletal conditions with a wide range of benefits including improving quality of life, there is little known about the prevalence of massage therapy utilization for musculoskeletal conditions specifically across the globe. The aim of this review is to report on the prevalence of massage therapy utilization in the treatment and management of musculoskeletal conditions with a view to assist future policymakers and key stakeholders in their decision-making around accessibility in health care.
METHODS
Search Strategy
A comprehensive search of peer-reviewed literature of four research databases, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Medline (Medical Literature Analysis and Retrieval System Online), EMBASE (Excerpta Medica Database), and AMED (Allied and Complementary Medicine Database), was conducted from January 2000 to January 2024. CINAHL and Medline are firmly established databases for health and medical scholarship. EMBASE is a trusted source of global, evidence-based pharmacological and biomedical research, incorporating the Emtree thesaurus, providing comprehensive indexing, and allowing for precise biomedical and life science information retrieval. AMED is the specialist authority from the Health Care Information Service of the British Library, offering access to resources regarding complementary and alternative medicine.
The search was undertaken through combining two key themes of “massage” and “musculoskeletal” respectively. Key words (KW) and their Mesh terms/headings (MH) were searched with “OR” inside each and combined later with “AND.” That is, for the “massage” component, key words “massag*”; OR MH “massage”; OR “deep tissue massage”; OR “sports massage”; OR “Swedish Massage”; were combined with “AND” for the “musculoskeletal” component which consisted of key words “musculoskeletal”; OR KW “muscular”; OR MH “Joint Instability”; OR MH “Finger Joint”; OR MH “Hand Joints”; OR MH “Hip Joint”; OR MH “Elbow Joint”; OR MH “Ankle Joint” OR MH “Knee Joint”; OR MH “Shoulder Joint”; OR MH “Sternoclavicular Joint”; OR MH “Tarsal Joint”; OR MH “Toe Joint”; OR KW “joint*”; OR MH “arthritis”; OR KW “Arthritis”; OR MH “Arthritis, Rheumatoid”; OR MH “Osteoarthritis”; OR KW “osteoarthritis”; OR MH “Osteoarthritis, Spine”; OR MH “Osteoarthritis, Wrist”; OR MH “Osteoarthritis, Knee”; OR MH “Osteoarthritis, Hip”; OR MH “Osteoarthritis, Cervical”; OR MH “Osteoporosis”; OR KW “osteoporosis”; OR MH “Chronic Pain”; OR KW “chronic pain”; OR MH “Knee Pain”; OR MH “Neck Pain”; OR MH “Chronic Pain”; OR MH “Back Pain”; OR MH “Myofascial Pain Syndromes”; OR KW “back pain”; OR KW “neck pain”; OR KW “hip pain”; OR KW “Shoulder Pain”; OR KW “Knee Pain”; OR KW “foot pain”; OR KW “hand pain.” In addition to this search process, hand searches of prominent peer-reviewed journals were conducted, and relevant articles were sought via Google Scholar and thorough examination of reference lists of identified publications was also undertaken.
Figure 1 details the process of how the search was refined to arrive at extracting the selected 38 empirical studies reporting on prevalence of massage therapy utilization for musculoskeletal conditions. The initial search identified 9,737 articles, all of which were imported into Endnote (X9.3.3™) which was used to sort and manage literature throughout the review. Once assessed for eligibility and after the removal of duplicates, title and abstract screening was undertaken by S. Ladanyi, and the potentially relevant studies were then assessed by S. Ladanyi and checked by D. Sibbritt. Excluded articles and any discrepancies were discussed and resolved and data from the remaining 38 eligible studies included in this review were subject to quality appraisal and were organized and tabled for evaluation (Table 1).

Inclusion Criteria
Only studies that reported in English on the prevalence of massage therapy utilization for musculoskeletal conditions were included in this review, regardless of duration of use. The term “massage therapy” in this review included generic styles such as effleurage, deep tissue, sports massage, and Swedish massage. “Musculoskeletal conditions” included those involving joint acute or chronic muscle or myofascial pain as well as disease processes directly relevant to and affecting musculoskeletal health such as rheumatoid arthritis, osteoporosis, and other degenerative/inflammatory musculoskeletal conditions such as osteoarthritis and arthritis.
Research studies reporting epidemiological data and health service utilization were included. Studies that reported prevalence of massage therapy utilization for musculoskeletal conditions directly were included, as were studies where massage therapy was reported among other CIM, but only if they reported on prevalence of massage therapy utilization for musculoskeletal conditions specifically. There were no restrictions on age ranges above neonates or infants (as per exclusion criteria), and no restrictions on gender. Only participants who utilized massage therapy for musculoskeletal conditions were included. Conditions were limited to those directly related to musculoskeletal conditions where massage was used for treatment. There were no restrictions on the country of publication, and the year of publication was limited to January 2000 to January 2024.
Exclusion Criteria
All articles reporting on reviews of the literature, randomized controlled trials, clinical trials, trials, intervention studies, experimental studies, editorials, conference abstracts, animal studies, case studies, protocols, news articles, and research published in a language other than English were excluded. In addition, studies reporting on pregnant women and pediatric or neonatal patients exclusively, as well as studies reporting on people experiencing malignancy, palliative care, or patients suffering any form of terminal illness, were also excluded. Specific types of massage therapy such as traditional Chinese massage, aromatherapy massage, and hot stone massage were also excluded, as were all studies on self-administered massage.
Quality Appraisal
A quality appraisal instrument specifically developed for the critical appraisal of health literature when prevalence and incidence of health problems are investigated(30) was adapted and used to evaluate the quality of the articles selected in the review via a 9-point scoring system (Table 2).(30,31) This scoring system was applied to all 38 studies included in the review. Authors S. Ladanyi and D. Sibbritt independently appraised and scored each of the 38 studies against the 9-point quality appraisal system. Judication of any discrepancies was conducted by J. Adams. The score for each article appears in Table 3.

Analysis
The prevalence for massage therapy utilization for musculoskeletal conditions reported in each of the studies was reported by sub-categories based on themes, including age, gender, population, condition, country and continent, year of publication, and sample size (defined as smaller (n < 1,000) or larger studies (n ≥ 1,000)).
Ethics Approval and Consent to Participate
According to the EQUATOR guidelines, this research was not conducted on humans and animals in the laboratory; therefore, ethics approval was not applicable.
RESULTS
The Overall Prevalence for Massage Therapy Utilization
Of the 38 studies included in this literature review, the prevalence for massage therapy utilization for musculoskeletal conditions ranged from 2%(32) in osteoporotic patients to 81.2%(33) in dental hygienists. For most of the studies in this review (n = 28), the prevalence of massage therapy for musculoskeletal conditions was mostly reported among other forms of CIM. Of all 38 studies, 22 reported massage therapy in the top three most commonly used forms of CIM for musculoskeletal conditions.(6,7,9,12,16,19,33–48) Among the 12 studies with a large sample size (n ≥ 1,000), the range of the prevalence of massage therapy utilization for musculoskeletal conditions was 2.2(49)–56%.(8) The highest prevalence of massage therapy utilization for musculoskeletal conditions was reported at 81.2% in dental hygienists(33) and 80.1% in rural farmers.(43)
Prevalence by Duration of Use
The range of prevalence for those who used massage therapy for musculoskeletal conditions for 12 months or less (n = 25) was 2.2(49)–80.1%(43); and 2% for those who used massage for more than 12 months but not lifetime (n = 1).(32) For studies reporting lifetime use of massage therapy (n = 9), the range of prevalence was 12(50)–62.7%.(36)
Prevalence by Age Category
The majority of studies included participants spanning adulthood. However, there were 10 studies that included participants with more specific age ranges. There were studies where the age of participants was 44 years or under (n = 2),(8,50) or 45 years or over (n = 8);(6,7,10,13,35,45,47,51) and one study included participants from both the 44 or under range (32–39 years) and the 45 or over age range (i.e., 62–67 years).(52) The prevalence of massage therapy utilization for musculoskeletal conditions for individuals 44 years or under (n = 2) ranged from 12%(50) to 56%(8) and for the 45 years or over age group (n = 8), the prevalences ranged from 4.8%(45) to 50.7%.(13) For the one study that reported prevalence of massage therapy use from two cohorts of women, the prevalence was higher among the younger women (42.4%), compared to the older women (25.2%).(52)
Prevalence by Gender
The majority of studies (n = 30) included both male and female participants. Six studies included women-only participants, reporting the prevalence of massage therapy use for musculoskeletal conditions ranging from 7.7%(10) in mid-older Australian women to 56%(8) in younger Australian women. There were no studies reporting on men-only participants. There were two studies that did not report the gender of the participants.
Prevalence by Population
Studies reporting on massage therapy utilization for musculoskeletal conditions among a general population (n = 9) reported a range of prevalence between 4.8%(45) and 49.7%.(44) In studies where participants were inpatients or outpatients with a specific condition (n = 10), the prevalence ranged from 12.3%(47) to 68.1%.(12) Of the three studies that reported on pain among pain registry and pain clinic patients, prevalences ranged from 16.3%(53) to 56%.(39) For a study reporting on adult complementary alternative medicine (CAM) users (from the general population) (n = 1), the prevalence was 22%.(41)
Prevalence by Condition
Conditions reported by participants in this review were categorized into seven categories. The prevalences for the categories are as follows: 10.5(37)–68.1%(12) for lower back pain/back pain (n = 10); 4.8(45)–63.2%(54) for osteoarthritis/arthritis/rheumatoid arthritis (n = 8); 2.2(49)–80.1%(43) for musculoskeletal pain (n = 6); 14.1(48)–62.7%(36) for “other” pain (n = 2); 7.6(11)–47%(55) for musculoskeletal injury (n = 3); 18(56)–50.7%(13) for general miscellaneous (n = 5); and 2% for osteoporosis (n = 1).
Chronic pain was noted in six of the studies included earlier(9,12,42,49,53,57) and two studies specifically on chronic pain for musculoskeletal conditions.(19,39) The prevalence overall for chronic pain ranged from 2.2%(49) to 68.1%.(12)
Prevalence by Region
The prevalence of massage therapy use by regions was as follows: 2.2(49)–81.2%(33) in North America (n = 14); 2(32)–56%(8) in Australia (n = 8); 12(50)–62.7%(36) in UK and Europe (n = 6); 14.2(51)–68.1%(12) in Asia (n = 9); and 80.1%(43) in Africa (n = 1).
Prevalence by Year of Publication
In the decade incorporating the years 2000–2011 inclusive, there were 15 studies with the prevalence of massage therapy utilization for musculoskeletal conditions ranging from 2%(32) to 62.7%.(36) In the following decade, from 2012 to 2023 inclusive, there were 23 studies with the prevalence of massage therapy utilization ranging from 2.2%(49) to 81.2%.(33)
DISCUSSION
This paper reports the first systematic review of the prevalence of massage therapy utilization specifically for musculoskeletal conditions. Our results from the 38 studies included in the review indicate a wide range of prevalence for the use of massage therapy for musculoskeletal conditions, 2(32)–81.2%.(33) The highest prevalence for massage therapy utilization in this review was reported for musculoskeletal conditions in dental hygienists (81.2%)(33) and rural farmers (80.1%).(43) Of the larger studies where the sample size was greater than 1,000 (n = 12),(6–8,10,19,34,35,37,41,49,51,52) the range of prevalence was 2.2(49)–56%.(8) These results demonstrate research interest in the utilization of massage therapy for musculoskeletal conditions in these studies. In addition, our findings provide insight into the variation in prevalence of massage use that occurs due to a range of factors.
Despite the correlation of pain being linked to musculoskeletal conditions and massage use, and that these conditions may progress over time, our findings indicated a higher prevalence of massage use among younger participants (44 years and under), 12(50)–56%,(8) than those 45 years and over, 4.8(45)–50.7%.(13) This unexpected finding may be due to the reasons for use by people in the different age ranges, where younger users have been shown in previous research to be more likely to use massage to support health-related life-styles,(50) and older people are more likely to seek massage therapy for remedial purposes relating to arthritic conditions(10,45) and pain,(6,7) as well as older individuals also using massage therapy complementary to conventional medical treatments.(47) Further, the difference in the prevalence of massage therapy use across age groups may also in part have been due to the limited number of studies conducted on participants aged 44 years and under as identified in our review (n = 2).(8,50) There would appear to be a need for further empirical investigation with a view to better determining the prevalence of massage use for musculoskeletal conditions across various age groups.
While some studies did not state the gender of the participants (n = 2),(11,19) most report on both men and women (n = 30). Within these studies that included both men and women, there was no reporting of gender-specific prevalences. Of the six studies reporting on female participants only,(6,8,10,13,34,52) all originated from Australia following investigation of the Australian Longitudinal Study on Women’s Health. There were no studies reporting on males specifically. Therefore, there is a clear gap in the literature regarding gender-specific prevalence of the use of massage therapy for musculoskeletal conditions.
For those more likely to use massage therapy for musculoskeletal conditions, our results indicate the widest range of prevalence is among the sub-group of the “general population” at 4.8(45)–49.7%(44); and 22% for adult CAM users in the general population.(41) General population participants who were also inpatients or outpatients with a specific condition reported the highest use of massage, 12.3(47)–68.1%,(12) followed by those with chronic pain, 2.2(49)–68.1%,(12) and “other pain” related to a musculoskeletal condition, 14.1(48)–62.7%.(36) These findings indicate a correlation between massage therapy use being common for inpatient and outpatient groups,(58) including those with chronic pain and other painful musculoskeletal conditions.(8,24,59,60)
These findings on general populations correlated with our findings on prevalence of massage therapy utilization for musculoskeletal conditions. We generated six different classifications of musculoskeletal conditions that emerged, with musculoskeletal pain in the form of lower back pain and back pain as the largest category. The highest prevalence for massage therapy utilization for musculoskeletal conditions was reported for musculoskeletal conditions in dental hygienists (81.2%) and musculoskeletal pain in rural farmers 80.1%,(43) followed by chronic lower back pain in neurosurgical outpatients.(12) These findings are consistent with other CIM studies reporting on the efficacy of massage therapy in achieving positive outcomes for those with pain(13,24,61) and suggest a high prevalence of massage therapy utilization for musculoskeletal conditions where pain is a central component.
Conversely, the prevalence of massage therapy was less popular among patients with osteoporosis (2%)(32) and among US veterans with musculoskeletal pain (2.2%).(49) These results may have occurred due to study design. For patients with osteoporosis, the survey did not include massage therapy as one of 12 possible CIM therapies for suggested treatment,(32) and, therefore, the response relied on participants stating this as an “other” therapy, rather than being prompted by the questionnaire item. Another study of prevalence related to US veterans included a large sample size (n = 468,806); however, the duration of massage inside this study was within a 3-month window; therefore, participants responded only if they used massage for a short period of time.(49) These differences in the definitions of CIM may have potentially limited the methodological design of these studies and as such impacted the quality of evidence and thus the findings. Further research for massage therapy utilization specifically is warranted to achieve more accurate results.
The majority of the studies included in this review originate from North America (n = 14), followed by Australia (n = 8), Asia (n = 9), and Europe (n = 6). One reason this review may have identified studies from these regions predominantly may be due to the inclusion/exclusion criteria where only studies in English were included. Our findings highlight that the lowest prevalence was reported in Australia (2(32)–56%(8)) and the highest prevalence was reported in North America (2.2(49)–81.2%(33)), although there was considerable overlap across all regions. A deficit in the knowledge base around massage use for musculoskeletal conditions in countries and regions where English is not a prominent spoken language may have impacted these results. Despite the lack of studies from these regions, there is evidence to suggest massage therapy is a popular form of CIM through one study in this review from Nigeria that reported the second highest prevalence for massage use (80.1%),(43) leaving the opportunity for future research.
While our study offers valuable insight into the prevalence of massage therapy utilization for musculoskeletal conditions, the results should be interpreted with caution due to the limitations of the review design. One such limitation is that only studies printed in English were considered in the review, potentially missing other relevant research in this area. Most data as reported were gathered via questionnaires or interviews, and this may have potentially created response bias. In addition, the methodological quality was variable across studies in this review. With the highest possible quality appraisal score of 9, the majority of studies (n = 35) scored 5 or greater. However, there was one study with a score of 1,(40) and two studies that scored 4.(16,50) Overall, the average score was 6.47/9. This scoring, combined with many of the studies being embedded in studies reporting on CIM more generally with varied definitions of CIM, may subject our results to selection bias, and such an issue should be considered when interpreting our findings.
CONCLUSION
Massage therapy is a popular treatment modality used among those suffering from musculoskeletal conditions. Implications for researchers, policymakers, and stakeholders involve the need for further high-quality epidemiological research in massage therapy use for the treatment of musculoskeletal conditions. Inpatients and outpatients with specific musculoskeletal conditions including pain should be included in future studies, as these groups have been shown to be high users of massage therapy. Musculoskeletal conditions with chronic pain/pain are a key motivator for those seeking the use of massage therapy; therefore, integrating healthcare benefits to subsidize massage therapy for older adults may be beneficial in the provision of services through accessibility. Future high-quality research on massage therapy utilization for musculoskeletal conditions specifically as a single form of treatment as well as age-, population-, and gender-specific studies with a focus on men across all regions will help contribute to the search for meaningful findings through sound methodology and evidence. In addition, the range of prevalences reported in this review was wide, and this is most likely the result of key methodological and population differences. This cannot be overlooked when interpreting results as evidence and can be positively applied to future research methodologies to improve the rigor and produce robust and reliable outcomes and findings.
