Chronic low back pain patients’ use of, level of knowledge of and perceived benefits of complementary medicine: a cross-sectional study at an academic pain center

Abstract

BackgroundChronic pain patients often use complementary medicine (CM) to alleviate their pain; however, little is known about the use of CM by chronic low back pain (cLBP) patients. We investigated the frequency of use of CM by cLBP patients, the perceived effects of these therapies, patients’ knowledge regarding CM, and patient-physician communication regarding CM.MethodA cross-sectional survey was conducted from November 2014 to February 2015. A questionnaire was distributed by physicians to 238 consecutive patients consulting for cLBP at the Pain Center of Lausanne University Hospital, Switzerland. Poisson regression model was used to analyze patients’ level of knowledge regarding various CMs, and the logistic regression model was used to assess CM use for cLBP.ResultsThe questionnaire was returned by 168 cLBP patients (response rate: 70.6%). Lifetime prevalence of CM use for cLBP was 77.3%. The most commonly used therapies were osteopathy (48.8%), massage (45.2%) and acupuncture (31.6%), rated for their usefulness on a 0–10 scale as a mean ± SD of 5.4 ± 2.7, 5.9 ± 2.5 and 3.8 ± 3.2, respectively. The CM treatment best known by patients was osteopathy, followed by massage and acupuncture. If their doctors proposed CM as a treatment for cLBP, 78% of participants reported being very or somewhat likely to try CM. Respondents with CM health insurance were more likely to use CM (OR = 2.26; 95%CI: 1.07–4.78; p = 0.031) for cLBP. Respondents having experienced cLBP for more than five years were more likely to use CM to treat their cLBP than respondents having experienced cLBP for one year or less (OR = 2.84; 95%CI: 1.02–7.88; p = 0.044).ConclusionsMore than three-quarters of cLBP patients in our sample did use CM to treat their cLBP. The results showed that the most commonly used therapies were not necessarily the highest rated in terms of perceived usefulness. These results highlight the importance of developing integrative pain centers in which patients may obtain advice regarding CM treatments.Electronic supplementary materialThe online version of this article (doi:10.1186/s12906-017-1708-1) contains supplementary material, which is available to authorized users.

Perspectives on the use of aromatherapy from clinicians attending an integrative medicine continuing education event

“…In the United States, it is estimated that 62% of adults have used some form of complementary or alternative therapy in the last 12 months [17], although adult use specifically of essential oils or aromatherapy is unknown. A recent Swiss study estimated that 10.7% of patients with chronic low back pain used aromatherapy and rated it a 4.2 out of a 10-point scale for usefulness [18]. Other studies have shown that aromatherapy may have health benefits, including relief from anxiety and depression, improved quality of life, improved sleep, and pain relief for knee osteoarthritis and renal colic [19–25].…”

Integrative Medicine: A Health Paradigm of the Future

“…111 Both techniques are now working on evidenced-based approach with positive characteristics, collaborating with conventional doctors, and receiving patients acceptance in the treatment of diverse pains. [112][113][114] Massage, reiki, shiatsu. Are manual therapies that prevent or correct mechanical derangements in association with muscles and skeleton, with benefits in short and long term, they have grown significantly.…”

Gua sha therapy for chronic low back pain

“…[ 13 14 ] Given these limitations of pharmacological therapies, it is unsurprising that 1 study showed 77.3% of non-specific LBP patients in Switzerland chose to consult a complementary and alternative medicine (CAM) at a local pain center. [15] Furthermore, the American College of Physicians has revised its recommendation guidelines to suggest CAM treatment options for the management of non-specific LBP. [16] …”
