This paper provides a meticulous review of the growing interest and utilization of complementary and alternative medicine (CAM) in the management of low back pain (LBP). It outlines the CAM therapies that are recommended in recent clinical practice guidelines. CAM therapies, including manual therapy, acupuncture, massage, yoga, and others, are discussed in terms of their effectiveness in treating different types of LBP. Moreover, the review discusses the need for additional scientific scrutiny of lessstudied CAM therapies, suggesting that high-quality randomized controlled trials and cost-effectiveness analyses are necessary to improve our understanding and outcomes for LBP patients.
Low back pain (LBP) is a ubiquitous condition that frequently leads to significant activity limitation, restriction in participation, absenteeism from work, and hospitalization [1,2]. Its prevalence tends to escalate with advancing age and is more commonly observed among females [3]. A global estimation done in 2020 shows over 619 million individuals being impacted by LBP [4]. The occurrence of LBP is irrespective of economic status, affecting high-, middle-, and low-income nations alike. The condition poses a substantial clinical and economic strain on healthcare systems due to its high prevalence [5]. LBP varies in its duration of persistence, and therefore it is typically categorized into three distinct types: acute, subacute, and chronic [6]. Acute LBP is brief, lasting fewer than six weeks; subacute LBP prolongs for a period between six and twelve weeks; whereas chronic LBP is identified by its long-term persistence beyond twelve weeks [6].
Additionally, LBP can be classified into three types: nonspecific (NSLBP), specific, and radicular [6]. NSLBP is the most common type of LBP, accounting for about 90% of cases. The term ‘nonspecific’ is derived from the absence of a discernible pathoanatomical source. While the origins of the pain could refer to an injury in the muscles, ligaments, joints, or discs, the precise tissues instigating the discomfort remain undetermined [6]. Specific LBP, in contrast, corresponds to an identifiable underlying cause or condition [6]. Examples could encompass pain resulting from a vertebral compression fracture, ankylosing spondylitis, or spinal malignancies. Specific LBP, in contrast, corresponds to an identifiable underlying cause or condition. Examples could encompass pain resulting from a vertebral compression fracture, ankylosing spondylitis, or spinal malignancies [6].
Contemporary clinical practice guidelines have recently undergone a paradigm shift, advocating non-pharmacological and non-surgical management of LBP, inclusive of complementary and alternative medicine (CAM), as first-line treatment strategies [7- 11]. CAM is now perceived as a complementary approach, symbiotic with traditional, conventional therapy [12]. The use of CAM to manage patients with LBP is gaining popularity. A study conducted on the German population found that 54% of patients with LBP received CAM therapy [13]. Likewise, in America, over 41% of individuals suffering from disabling LBP reported resorting to CAM therapy, with an appreciable 58% attesting to its effectiveness [14]. Furthermore, approximately 44% of American women diagnosed with LBP sought treatment from both conventional and CAM practitioners [15]. This percentage was higher among Australian women, with 63% consulting conventional and CAM practitioners to manage their LBP [16]. A survey conducted in Canada revealed that 39% of chronic LBP patients had received CAM [17]. In Hong Kong, 72% of Chinese patients with LBP sought CAM therapy [18].
CAM therapies encompass a wide range of non-mainstream practices, such as acupuncture, manual therapy, chiropractic manipulation, massage therapy, osteopathy, herbal medicine, aromatherapy, homeopathy, meditation, hypnotherapy, yoga, Tai Chi, Qi Gong, and other approaches [12]. However, not all of these approaches have been explored in previous studies [19]. A systematic review conducted in 2020 evaluated the quality of clinical practice guidelines for patients with LBP and identified 22 guidelines offering recommendations for certain types of CAM therapy [19]. The subsequent guidelines that were published after this review have increasingly incorporated recommendations on CAM therapy [9, 20-27]. This review critically discusses the recommended management strategies for LBP patients utilizing CAM therapy, as expounded in the extant body of literature and evaluated in contemporary clinical practice guidelines.
Manual therapy, including mobilization or manipulation, was recommended for acute and subacute NSLBP patients [21, 28-30]. Certain guidelines also recommended its use for chronic cases [21,28,31]. Conversely, certain guidelines deemed the existing evidence either inconclusive or insufficient to advocate manual therapy for NSLBP patients [24, 31, 32]. The scenario is similar for massage therapy in managing NSLBP; certain guidelines recommend it for both acute and chronic cases [28], while others only prescribe it for chronic [21] or acute and subacute incidents separately [29]. Conversely, other guidelines found the evidence to be inconclusive to recommend massage therapy to NSLBP patients [24, 32]. In regard to the application of yoga, it was recommended by the American Physical Therapy Association (APTA) [28], the North American Spine Society (NASS) [24], and the American College of Physicians (ACP) [29] for chronic NSLBP. However, the Department of Veterans Affairs and the Department of Defense (VA&DoD) [31] concluded that the available evidence is insufficient to support a recommendation for its use. One guideline, the ACP guideline [29], recommended Tai Chi as a treatment option for chronic NSLBP. Qi Gong remains a subject of controversy in relation to both acute and chronic NSLBP [31]. Pilates was also recommended as a potential treatment for chronic NSLBP [28].
Acupuncture was recommended for acute and chronic NSLBP in three guidelines [27,29,33], while its effectiveness remains uncertain according to two guidelines [24,32]. The APTA recommended dry needling for acute cases [28], but the NASS guideline did not provide a conclusive recommendation [24]. The China Association of Acupuncture-Moxibustion’s clinical practice guideline [33] suggested electroacupuncture, auricular acupuncture, moxibustion, and cupping therapy for both shortterm and long-term NSLBP. The VA&DoD guideline [31] found the evidence insufficient for auricular acupuncture and cupping therapy.
Manual therapy was recommended as a treatment option for patients with acute radicular LBP [9,22]. The effectiveness of massage therapy has been considered controversial for radicular LBP patients [34]. Acupuncture has been recommended for patients with subacute radicular LBP [22], although other guidelines suggest against its use regardless of the presence of radiculopathy [8,9].
The effectiveness of manual therapy for patients with lumbar disc herniation remains a subject of controversy [35]. The Korean medicine clinical practice guideline [25] recommends acupuncture, moxibustion, and Tuina manual therapy for lumbar intervertebral herniated disc patients.
In conclusion, there is a significant paradigm shift toward CAM therapies in the management of LBP. This has resulted in a surge in clinical practice guidelines evaluating the efficacy of these CAM therapies. Despite this, only a small number of CAM therapies have undergone rigorous testing and scientific scrutiny. Therefore, there are research gaps in our understanding of the efficacy of the entire spectrum of CAM therapies. Thus, there is an imperative need to examine CAM therapies that have not been adequately investigated. To examine these untapped therapies, high-quality randomized controlled trials are needed. This should ideally be coupled with cost-effectiveness analyses in order to improve our comprehension of the economic impact of CAM therapies. Such efforts can provide greater awareness of CAM treatment options for LBP, facilitate therapy selection based on evidence, and ultimately improve outcomes for those suffering from this debilitating condition.
