Abstract: Traditionally, musculoskeletal pain management has focused on the use of conventional treatments to relieve pain. However, multi-modal integrative medicine including alternative/complementary treatments is becoming more widely used and integrated into treatment guidelines around the world. The uptake of this approach varies according to country, with generally a higher uptake in developed countries and in females aged more than 40 years. Integral to the concept described here, is that the body has an innate ability to self-heal, which can be optimized by the use of integrative medical strategies. Stress triggers for acute or recurring musculoskeletal pain are diverse and can range from physical to psychological. The mechanism by which the body responds to triggers and initiates the self-healing processes is complex, but five body networks or processes are thought to be integral: the nervous system, microcirculation/vasodilation, immune modulation, muscular relaxation/contraction and psychological balance. Multi-modal integrative medicine approaches include nutritional/dietary modification, postural/muscular training exercises, and cognitive behavioral mind/body techniques. This article will review the self-healing concept and provide plausible scientific evidence where available.

Pain influences quality of life and can be responsible for impairing autonomy, decreasing independence, and decreasing functional capacity.1 The definition of pain has recently been re-defined by the International Association for the Study of Pain (IASP) to “An unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage” (IASP 2020),2 and the definition of chronic pain was re-defined by the World Health Organization (WHO) in 2018 to “when pain has persisted for more than 3 months and is associated with significant emotional distress and/or functional disability, and the pain is not better accounted for by another condition” (WHO CD-11, 2018).3
Musculoskeletal pain affects the bones, muscles, ligaments, tendons, fascia and nerves. It can be acute (having a rapid onset with severe symptoms), and become recurrent with age, or can be chronic (long-lasting). Musculoskeletal pain accounts for 14% of all years lost to disability world-wide4 and includes localized pain such as low back, knee, shoulder, myofascial pain syndrome, and more widespread pain such as seen in fibromyalgia. The cause of musculoskeletal pain is not always clear,5 but known triggers include obesity,6–8 trauma and injury,9,10 overuse,11 aging,12 inflammation,13 and mental health disorders.14 In some cases, musculoskeletal pain is exacerbated by physiological hypersensitivity known as centralization, an increase in the excitability and synaptic efficacy of neurons in nociceptive pathways, often independent of inflammation.15
Traditionally, musculoskeletal pain management has focused on the use of conventional treatments such as rehabilitation, non-steroidal anti-inflammatory drugs (NSAIDs), occasionally surgery, and even opioids to relieve pain. However, integrative medicine, which incorporates complementary and alternative medicine such as acupuncture, exercise, natural remedies and medical devices are becoming more widely used and integrated into guidelines around the world,16 including as first-line treatment (Table 1).
Table 1 International Guideline Recommendations for Acute Low Back Pain
The American Board of Integrative Holistic Medicine (ABIHM) describes integrative medicine as focusing on the whole person, and making use of all appropriate therapeutic approaches to promote optimal health and healing. In light of the potential adverse effects associated with most pharmacotherapies, whole person healing is an age old philosophy more frequently being revisited.17
The use of integrative medicine therapies can potentially enable a self-managed approach. However, although patients with high health literacy are likely to be able to self-manage their musculoskeletal pain, patients with low health literacy, may seek care from healthcare professionals (HCPs). This indicates a need for both HCPs and patients to be educated on the self-healing concept.18
Whole person self-healing is a centuries old philosophy that has been refined using up-to-date research, to form the self-healing concept. For individuals with acute or recurrent musculoskeletal pain, body networks integral to the self-healing process, optimized by multimodal therapies, can help restore the whole person to equilibrium. This article will review each aspect of the self-healing concept and provide plausible scientific evidence where available.
Musculoskeletal Pain Triggers
Musculoskeletal pain can be localized or more widespread, such as in conditions like fibromyalgia, or can be due to myofascial pain syndrome (an independent cause of chronic pain that compounds the pain of other conditions). The causes of musculoskeletal pain can vary. Muscle tissue can become damaged in many ways including by the wear of daily activities, localized trauma, repetitive movement, postural strain, mental stress, and older age. Many patients with musculoskeletal pain do not have a systemic disease or medical condition underlying the musculoskeletal pain experienced, and the cellular and molecular mechanisms are unclear. The sensation of musculoskeletal pain is mostly due to deep-tissue damage or strain, probably through activation of the polymodal muscular nociceptors. The intensity and duration of pain can determine the intensity of generalized muscle hyperalgesia and the potential transition from acute to chronic pain.19–21
Body posture refers to body position and the alignment of body parts in relationship to the environment and is influenced by each joint.22 Posture is maintained by tonic muscle contractions acting against gravity and stabilizing the positions of body segments. The links between posture and pain are highly complex and controversial, but studies have shown that some habit forming posture, as reported in postural awareness questionnaires, may lead to chronic pain or further deterioration.22,23 Additionally, a sedentary lifestyle can be associated with a higher risk of musculoskeletal pain24 possibly due to muscle atrophy, caused by suppression of muscle protein synthesis as well as fiber denervation, neuromuscular junction damage, and upregulation of protein breakdown which can affect glucose homeostasis.25
Aging is associated with a loss of muscle mass, strength, and function that may result in sarcopenia, characterized by changes in muscle fiber size and type, motor nerve unit alterations and fatty infiltration of muscle.26 In addition bone strength, cartilage resilience, ligament elasticity and muscular strength reduce with age and fat redistribution increases with age, all of which diminish normal functioning of tissue.27 Studies predict that as the average age of individuals increases globally, musculoskeletal pain will become more widespread.12
Intense Physical Activity
Intensive work- and sport-related physical activity, can cause physical stress on muscle (peak mechanical loading) and along with sustained and/or repetitive movements, can present stress triggers for the development of tissue damage and musculoskeletal pain.11
Trauma and Injury
Musculoskeletal pain caused by trauma and injury (vehicle accidents, sprains, falls, fractures, dislocations, and direct blows to the muscle) can be prolonged. A recent study has shown that after trauma/injury, at 4 months 11% of patients developed moderate-to-severe pain and 21% had symptoms immediately after injury that were prolonged.10
Depression and Mental Health
Pain and disability are linked to a range of psychosocial and physical factors. For example, depression can affect pain and disability.14 Furthermore, a link has been found between harassment (workplace bullying) and musculoskeletal pain.28 One hypothesis for the link between mental health and pain, is that raised anxiety may lead to increased muscular tension, which in turn may lead to increased pain.29 In the context of chronic pain, hippocampal connectivity to the posterior insula and anterior cingulate cortex (ACC) has been associated with negative attentional bias, increased sensitivity to unpleasant stimuli, and pain catastrophizing involving the insula, ACC and dorsolateral prefrontal cortex.30
Traditionally, it has been argued that obesity is a trigger for musculoskeletal pain because of increased mechanical loading. However, conflicting studies have indicated that this may be a simplistic view.6–8 Adipose tissue is an endocrine organ secreting cytokines (adipokines) that contribute to inflammation and hormones, some of which may be associated with the musculoskeletal pain.31 A recent systematic review shows that increased body fat, not body weight per se, is likely to be associated with low back, knee, and foot pain.32
Persistent inflammation is a stress trigger that may contribute to all non-traumatic musculoskeletal pain, in particular ageing-related pathologies such as osteoporosis, osteoarthritis, and sarcopenia.13 The inflammatory response involves many proinflammatory cytokines and chemokines and the termination of this response is critical to prevent unwanted tissue damage.13 Oxidative stress can also lead to chronic inflammation. In patients with fibromyalgia, it has been shown that increased oxidative stress may play a role in the etiology and pathogenesis of musculoskeletal pain.33
An Integrative Medicine Approach to Managing Pain
An integrative medicine approach to manage pain incorporating complementary/alternative therapies (Table 1) has become more widespread in recent years and more accepted by both patients and HCPs although this differs widely by country and region. There are many reasons for the potential inclusion of complementary/alternative therapies in guidelines: conventional therapies do not always adequately address the needs of the growing number of patients living with chronic pain, and often treat the symptoms of the disease without effectively addressing the underlying causes. A reduced reliance on conventional analgesic medicines can help limit the adverse effects, including opioids, NSAIDs, antidepressants, anticonvulsants (anti-epileptics), and corticosteroids.34,35 In contrast, complementary/alternative therapies mostly have minimal side effects.35 Integrative medicine approaches also encompass psychosocial factors (interaction of social factors and an individual’s behavior and mental health) and can help maintain both psychosocial and spiritual health through techniques such as mindfulness. Other activities such as yoga and physical exercise can help mental health and reduce depression which can likewise reduce pain.14,36
Integrative medicine approaches to the management of pain have been studied in a range of patient groups and settings. Petri et al discussed self-management of pain and integrative medicine programs as part of treatment plans for service personnel and concluded that they could be effectively incorporated. They did, however, add that further education, international collaboration, and research were necessary to increase use.37 Another study of American service personnel found that a change in mind-set towards integrative medicine approaches can bring benefits. For example, swapping the order of therapy, eg, to start with yoga, massage chiropractic care, or acupuncture, before moving to drugs and other traditional interventions, resulted in lower levels of pain.38 Integrative medicine approaches are also used in palliative/long-term care settings where such approaches have shown they can be used to help patients meet their spiritual needs (expectations for meaning, purpose, and value in life).39 A pilot project of quantitative and qualitative outcomes from complementary and integrative medicine healthcare in a long-term care facility suggested that integrative medicine approaches can be safely implemented and may provide pain relief and enhanced well-being for residents.40 In addition, the effect of integrative medicine on pain management in a tertiary care hospital setting has been shown for hospitalized patients, to have a significant impact on pain scores self-reported pain was reduced by 50% without increased risk of adverse effects.41
Uptake of Complementary/Alternative Medicine Across the World
Numerous studies have evaluated the factors determining the use of complementary/alternative medicine between different populations and countries. A systematic review of 49 studies from 15 countries showed that adults were more frequent users of complementary/alternative medicine than children, with use higher in East Asian countries such as Japan, South Korea, and Malaysia.42 In a study from the USA, use was similar across regions, with the populations most likely to employ complementary/alternative medicine being Asian and Caucasian, college educated, women, and those aged 45 to 64 years.43 Other studies assessing the sociodemographic determinants of complementary/alternative medicine use in 21 European countries also found that use was more prevalent among those employed, with a higher education and middle-aged women, with the oldest and youngest age groups least likely to uptake this type of medicine.44,45 Further, the type of complementary/alternative medicine varied according to income level, with lower income associated with the use of mind-body therapies, and higher income associated with the use of traditional and alternative medicines or manual body-based therapies.45 In Europe, complementary/alternative medicine use further varied by country, for example complementary/alternative medicine use is widespread in Germany and France, but the uptake is not as high in Nordic countries.44 Studies in the UK and Australia reported similar patient profiles, with complementary/alternative medicine use more common in women, those with a higher education and those >40 years, though users in Australia were more likely to have a chronic condition.46,47 In the UK, the choice of complementary/alternative also varied according to geographical location and socioeconomic status.47 Conversely, in developing countries, complementary/alternative medicine uptake was less likely. For example, a study in Brazil found that the prevalence of complementary/alternative medicine use was 4.5%. However, complementary/alternative medicine use was still more common in females, those aged >40 years, and those with a higher education. Type of complementary/alternative medicine use varied according to socioeconomical status, with upper social classes commonly accessing acupuncture and homeopathy and lower social classes using medicinal plants and herbal remedies.48
Self-healing is described as an intrinsic ability that has developed throughout evolution,49 and is in line with the Greek ideal of whole person healing. Psychology plays an important role within the self-healing process and there are psychological aspects to pain even within the conventional IASP 2020 definition “An unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage”.2
The self-healing concept is an integrated set of body practices applied in the prevention and rehabilitation of a wide range of organic, physical, and visual diseases. The application of these techniques stimulates and balances the organic, physical, psychological functions in a harmonious way, as it allows the development of a dialog between the body, the mind, the emotions, and the sensations.50 It has been shown that health promotion programs in stress management, fitness, nutrition, weight control, and self-medication improve health conditions; however, the impact on self-healing among people with acute and chronic diseases has also been shown to be mixed.51
Self-healing in the context of acute and recurring musculoskeletal pain is the innate process of the body and mind, to promote body networks to return to equilibrium and relieve pain. This may be regulated and optimized by the use of multimodal integrative therapies and refers to a naturally occurring sequence of events, not only of the body but also of the mind. Equilibrium refers to the condition in which all acting influences are balanced or canceled by equal opposing forces, resulting in homeostasis.52 When a stress trigger occurs, homeostasis is, or is perceived to be, threatened.53,54 Stress triggers for acute or recurring musculoskeletal pain are diverse and can range from the physical (eg, obesity and weight gain32) to the psychological (eg, depression14). The mechanism by which the body responds to triggers and initiates self-healing processes is complex, but five body networks are potentially thought to be involved: the nervous system,53–56 microcirculation (vasodilation/vasoconstriction),57–60 immune modulation,55,61 muscular relaxation/contraction,11,59,62,63 and psychological balance.55,64–68 Multi-modal integrative medicine approaches use multiple body networks to act on the whole person and therefore potentially help optimize the self-healing process. Approaches include nutritional/dietary modification, postural/muscular training exercises, and cognitive behavioral mind/body techniques.
Body Networks Associated with Self-Healing – Mode of Action
The cause of musculoskeletal pain is not always clear and the response of the body to musculoskeletal pain triggers is complex. The body networks described above can be associated with the innate ability of the body and mind to promote mechanisms to return to equilibrium, in order to help relieve pain induced by various triggers (the self-healing process) (Figure 1).
Figure 1 Self-healing concept: biological systems and mode of action.
Muscle consumes the most energy of all organs in the body, by forcing other body systems to regulate blood flow and provide delivery of energy.11 Muscle contraction via actomyosin fibers occurs in response to neuronal stimulation and an influx of calcium from extra and intra-cellular sources.63 Muscle contraction commonly associated with certain painful conditions restricts blood flow which suggests that muscle relaxation is associated with an increased supply of oxygen and nutrients to muscle.59
The ability to match muscle blood flow to metabolic demand shows good musculoskeletal health. The microvasculature takes part in metabolic homeostasis by supplying oxygen and nutrients to active muscle fibers and helps remove metabolism byproducts.59 An increase in microcirculation may promote healing and reduce pain. Sufficient microcirculation is therefore necessary after blunt injury, to maximize the number of functional contractile elements.58 The degradation of microcirculation is linked to the chronification of pain and can increase the risk of neck/shoulder and low back pain.57,60
Immune System Activation/Suppression (Inflammatory Mediators of Regeneration)
Reestablishing blood flow and tissue regeneration is a necessary component of healing and ultimately of pain relief. Acute inflammation plays a critical role in almost all stages of regeneration of muscle and other elements following trauma. Early in regeneration, necrosis of injured cells is triggered in response to trauma and chemotactic factors and cell contents are released to the extracellular space. Many types of immune cells infiltrate including neutrophils and mast cells and help remove damaged myofibers at the site of injury as cytokines recruit more immune cells like macrophages. A cascade of cellular responses is triggered to regulate muscle stem cell activation, proliferation and differentiation and encourage muscle regeneration which can help avoid chronic inflammation and relieve pain.55
The autonomic nervous system bridges the central and the peripheral nervous systems and its activation is key to pain mechanisms. Sympathetic activation (and parasympathetic inhibition) by a stress trigger is associated with muscular contraction and pain.55 The sympathetic nervous system governs the “fight or flight” response, and is associated with an increase muscle tone, whereas the parasympathetic nervous system regulates the “rest and digest” response, and is associated with a decrease in muscle tone.53,54 To trigger the relaxation response, the parasympathetic nervous system blocks the stress response to slow heart rate processes, increases intestinal and gland activity, and in the gastrointestinal tract enables relaxation of sphincter muscles.53,54 The relaxation response may promote restoration and healing of the body by decreasing the physiological and psychological burden of chronic stress.56
Psychological and cognitive strain, specifically in the case of catastrophizing or mental stress, may result in increased pain duration, muscle contraction, and can foster the transition from acute to chronic pain. Catastrophizing is a form of pain-specific psychological distress triggered by fear, which is characterized by a tendency to magnify the negative effect of pain.68 The presence of catastrophizing behavior predicts negative pain outcomes including chronic pain intensity, post-surgical pain intensity, disability, use of opioids, and persistent post-surgical pain.64 One study showed that catastrophizing was at least seven times more likely to predict the risk of subsequent chronic pain than any other factor among patients with acute back pain.69 Studies have also shown increased muscle activity not explained by physical load can be triggered by mental stress.55 Psychological factors play a significant role in the transition from acute to chronic pain;67 indeed, the psychological impact of a non-specific diagnosis can lead to “nonrecovery”. For example, in a cohort of patients with arm, neck, and shoulder issues, 38% of patients with a specific diagnosis reported “nonrecovery” which increased to 49% after 6 months.66
Integrative Medicine Within the Self-Healing Concept
There are a multitude of integrative medicine approaches which can be applied to the self-healing concept (Figure 2). A common theme of all the therapies discussed is that they promote well-being and mental health and connect the body and the mind, an ideal central to the whole-person self-healing concept.
Muscle strengthening through moderate exercise is linked to an increase in microcirculation associated with muscle contraction/relaxation.14,36 Intense physical activity can initiate musculoskeletal pain, but conversely, moderate physical activity can reduce it. Exercise and mechanical load on muscles causes hypertrophy (increased muscle mass induced by injury and hence repair and fusing of myofibers) and increases muscle strength.70 One approach to muscle strengthening is that of blood flow restriction training which takes advantage of hypertrophic repair and promotes neural and hypertrophic adaptations through a variety of endocrine, neural and metabolic mechanisms.71,72 A mind-body approach to exercise is that of Feldenkrais, internal awareness of movement and expanding the repertoire of movement has been shown in a randomized trial of 53 patients to significantly improve pain.73
Muscle strengthening through physiotherapy is also linked to microcirculation and muscle contraction/relaxation. Physiotherapy provides a well-documented and important benefit in the management of musculoskeletal pain, although it requires sustained effort on the part of the patient.74 Stretch exercises to improve flexibility can help limit musculoskeletal pain by preventing repetitive strain and musculoskeletal injuries and improve mobility as shown in a single-blind 12-week research study.75 Regarding posture, every individual has a unique postural force/torque signature and muscle coordination strategies that induce differing degrees of mechanical wear of their musculoskeletal systems which may increase the risk of developing musculoskeletal disorders for some individuals.76 Spinal manipulation can improve musculoskeletal pain; it has been suggested that mechanical force initiates a cascade of neurophysiological responses from the peripheral and central nervous system.77
Dietary patterns have an integral role in musculoskeletal health. A systematic review indicated that a high protein, fat, and sugar intake were associated with increased pain intensity and a lower pain threshold. Conversely, plant-based diets might relieve chronic musculoskeletal pain.78 Furthermore, a high fat diet has also shown to be associated with increased pain in animal models.79 An integrative review of 17 studies has also revealed that different nutritional interventions with specific diets, oils and/or fatty acids reduce musculoskeletal pain. In addition, nutritional interventions decreased the levels of several inflammatory markers including interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α.80 Vitamins have also been shown to promote musculoskeletal health.81 The active form of vitamin D directly regulates musculoskeletal function, it is involved in cell proliferation, myogenesis, regulation of protein synthesis, differentiation, and mitochondrial metabolism through pathways including the mitogen-activated protein kinase pathway(s).81 Vitamin B is considered to have a role in bone health which is connected to musculoskeletal health.82
The bridging of Western and traditional Chinese medicine has been described as shifting compensatory homeostasis to overall human body homeostasis, in line with the self-healing idea,83 and among older Chinese adults, the use of traditional Chinese medicine has been shown to be effective, although there are some conflicting results.84,85 For example, menthol acts on vasculature directly in the vascular smooth muscle and endothelium and recent studies have shown that it causes an indirect vascular response via sensory fibers86 and menthol gel can acutely reduce pain intensity.87 Cold therapy can reduce edema in acute situations; vasoconstriction occurs both in response to reflex and local cooling of the skin; however, patients should be aware than cooling longer than 20 minutes can be harmful as a sudden switch to vasodilation can be triggered (hunting reaction).88 Conversely, heat therapy can be used to relieve pain and muscle cramps and increase blood flow and facilitate tissue healing.89 A randomized trial of 219 patients in 2003 showed low continuous heat wrap therapies to be effective for the treatment of acute, nonspecific low back pain,90 a result consistently confirmed in smaller more recent trials.91,92
Devices and Techniques
More and more devices are coming onto the market, for example portable transcutaneous electrical nerve stimulation (TENS) machines.93 TENS provides localized strong yet comfortable muscle contractions to ease musculoskeletal pain.93 Microcurrent Electrical Therapy (MET) is another portable system for patients, activating central pain modulatory mechanisms using resonant frequencies. Cells communicate throughout the body via the extracellular fluid and the circulatory system via cell-surface receptors.94 Acupuncture is effective for a number of chronic pain conditions as reported in a meta-analysis showing effects of acupuncture were persistent over time, and were not affected by placebo.95 Additionally, a systematic review has shown that acupuncture has an analgesic effect on the hypersensitivity of musculoskeletal pain caused by central sensitisation.96 Infra-red saunas have also been shown to affect the autonomic nervous system, placing the body in the parasympathetic (rest and digest) state and allowing it to heal.97 Additionally, infra-red can optimize the immune system as shown by the white blood cell profile and cortisol levels in athletes and non-athletes.98 Ultra low dose radiation is possibly helpful to enhance blood circulation and metabolism within the human body.99
Yoga, mindfulness meditation, CBT and hypnosis are therapies that use psychological techniques to promote self-healing. Yoga combines physical exercises, meditation, and respiratory techniques that relieves stress whilst strengthening muscles.100 It also helps the body and mind to adapt to depression and anxiety and has a calming and relaxing effect on the individual. Studies have associated the practice of yoga with the relief of many chronic conditions such as low back pain.100 Mind–body interventions such as yoga may be integral to the integrative treatment of chronic pain conditions as they allow self-management.100 Mindfulness is a mediation practice associated with changes in cognitive, sensorial experience and brain activity that has been shown to reduce levels of pain across a wide range of pain-related disorders including fibromyalgia.101–103 After a four-session meditation intervention, during a noxious heat stimulus, there was a mean 40% reduction in pain intensity and 57% reduction in pain unpleasantness ratings.103 In a small trial in Scotland of 34 patients, mindfulness meditation as a sole therapy for some involved a period of change which may help with painful and chronic conditions.104 Additionally, therapies such as cognitive behavioral therapy (CBT) are based on the concept that, “thoughts, feelings, physical sensations, and actions are interconnected”.105 CBT has been shown to improve quality of life following 10 weeks of treatment.105 With regard to hypnosis, a study of healing in cancer patients could be applicable to musculoskeletal pain; the results from a recent study concluded
The intrinsic capacities of hypnotic phenomena, can be harnessed to effect perceptual and functional changes to offer symptom relief, re-establishment of systemic homeostasis, amelioration of cellular chemistry, and the acceleration of tissue healing.106
The concept of self-healing aims to harness the innate ability of the body and mind to promote mechanisms to return to equilibrium, in order to help relieve pain induced by various triggers. Self-healing is potentially optimized by the use of multi-modal integrative medicine strategies which act on the whole person. The mode of action and science behind the process has been discussed throughout this article.
The uptake of integrative medicine is starting to increase around the world and is now present in many guidelines (Table 1), possibly as a reaction to the misuse of opioids in the US107 and Europe,108 and side effects of these and other conventional therapies.34,35 In addition, a systematic overview of current studies indicates that conventional pharmacological treatments have short-term benefits, whereas interventions such as exercise therapy and psychosocial interventions show moderate to strong evidence for reducing musculoskeletal pain in the longer term, although more clinical trials are needed.109 Whilst integrative medicine is becoming more widely used and incorporated in guidelines around the world, including as first-line treatment (Table 1), there is also a need for guidelines that focus more on self-managed approaches to acute or recurrent musculoskeletal pain.
Multi-modal integrative medicine as part of the self-healing concept is compatible with a self-managed patient-centered approach. Patient self-management of care has been shown to be associated with lower healthcare use across primary and secondary care.110 Previous examples of successful patient self-management for pain are numerous; an Australian program guiding patients in pain management strategies showed significant improvements in patient self-reported pain and health distress.111 Additionally, it has been shown that optimized antidepressant therapy following self-managed pain resulted in less depression and some reduction in musculoskeletal pain severity112 Musculoskeletal pain was reduced following a community-targeted program111 and further, significant improvements in back pain have been demonstrated using exercise and self-management when compared with continued general practitioner management.113
There is a need for education about this self-healing multi-modal integrative medicine approach for both patients and HCPs; however, patient health literacy needs to be taken into account and approaches to education and self-management may need to be tailored to the patient. The Institute of Medicine reports that of the American adult population 50% may find acting on health information problematic.114 Furthermore, in a cross-sectional study, patients from Italy with low health literacy preferred a doctor–patient relationship whereas patients with high health literacy preferred a patient-centered approach.18 There are examples of education in the literature for acute or recurrent musculoskeletal pain although these would need to be tailored to the self-healing concept. Examples include a self-exercise education program for individuals with chronic low back pain which helps restore function and quality of life115 and a smartphone app, which could be a feasible way to implement both education and musculoskeletal care.116 There is also evidence in the form of a qualitative systematic review and meta-synthesis that intermittent self-care support such as peer support and booster sessions might be of importance.117 Also of paramount importance, is that when HCPs are approached by patients with musculoskeletal pain, a correct diagnosis is made in order to avoid inappropriate treatment or delay in receiving the correct therapy.
Although there is literature evidence to link the mode of action of musculoskeletal pain with the body networks (immune system modulation, nervous system, muscular relaxation/contraction, microcirculation/vasodilation, and psychology), there are still many open-ended questions regarding integrative medicine as part of the whole person self-healing concept. As patient and HCP confidence in using multimodal integrative medicine therapies grow, more studies will be undertaken exploring integrative medicine options and analyzing how musculoskeletal pain is triggered and relieved. In the future, it will be necessary to undertake large-scale studies and develop guidelines for multimodal integrative medicine based on these results. In addition, promoting awareness and understanding of the self-healing concept will be needed in addition to undertaking economic studies so alternative approaches can be reimbursed. Limitations to the self-healing approach include a lack of similar models for comparison and the need for more evidence to evaluate the effectiveness of integrative medicine approaches versus conventional therapy. Limitations to the analysis presented here include lack of large studies with adequate controls and that many studies are lacking in statistical power. Self-healing is hopefully a concept that will continue to evolve over time. The body has an innate ability to self-heal. The use of integrative medicine potentially helps to optimize the self-healing process and aids the body to return to its innate equilibrium, helping to relieve pain induced by various triggers. The self-healing concept is a multi-modal integrative medicine approach for adults with acute or recurrent musculoskeletal pain targeting whole person healing. Adequate guidelines and dissemination of education on the approach will all contribute towards the self-healing concept.
