The following referenced below are not an exhaustive list of all c
hiropractic research, however, they do represent a concise summary of the latest peer-reviewed literature that supports the use of spinal manipulation (the most notable chiropractic therapy) for common musculoskeletal conditions. While this discussion emphasizes spine manipulation, it should be noted that at Advanced Healthcare, Dr. Pisarek treats his patients with multi-modal therapy (e.g., mobilization, soft-tissue therapy, stretching and strengthening exercise therapy, lifestyle & ergonomic advice, nutritional recommendation, etc). Also included here is information on ways the contemporary chiropractic profession is improving on its evidence-base.
Mechanical Low Back Pain
Few other health care interventions have been assessed as extensively as spine manipulation for low back pain, both in terms of safety and effectiveness. A 2010 systematic review concluded that spine manipulation achieves equal or superior improvement in pain and function than all other commonly used treatments for acute low back pain (See reference 1). In fact, even the American College of Physicians and the American Pain Society have recently recommended that spine manipulation be considered for people who do not improve on their own (See reference 2). Indeed, a recent, hospital-based study found that a combination of medication, progressive exercise, and spine manipulation offered patients significantly greater improvement than ‘usual-care’ (See reference 3). Moreover, a high-quality 2012 medical study found that spinal manipulation was significantly better than the NSAID medication Diclofenac and also clinically superior to placebo (See reference 4).
In "Chiropractic Reduces Cost and Medication Use" published March 28, 2016, the authors of this article point out that previous research has found that patients receiving chiropractic care have lower associations of probability of disability recurrence than patients of physicians and physical therapists. They also state that early use of magnetic resonance imaging (MRI) has been linked to prolonged disability, higher costs, and greater use of surgery without evidence of benefit on health and function.
The goals of the above study were to assess the cost outcomes of treatment approaches to care for back problems in a major self-insured workforce, using published guidelines to focus on low back pain. The study involved a retrospective time series analysis of tracked episodes of three types of ICD-9 code–identified back problems (n = 14,787) during 2001 to 2009 from a Fortune 500 company (See reference 15).
The chiropractic group had the lowest prescription medication rates, least costs per episode of low back pain, and least guideline-incongruent use of medications and imaging. The chiropractic group also was the least likely to receive complex medical procedures like surgeries. Complex medical management costs were greater than 4 times more expensive for an episode of low back pain (over 3 years) with neurological findings than chiropractic care ($6983.82 vs $28,231.5). Physical therapy costs were more than double per episode of low back pain (over 3 years) with neurological findings compared with chiropractic care ($6983.82 vs $17,193.92). Similar cost savings in favor of chiropractic were found for an episode of low back pain (over 3 years) without neurological findings (chiropractic care = $6768.43, complex medical management = $29,344.25, physical therapy = $13,448.82).
Of note is that the complex medical management approach recorded the highest rates of prescription fills for opiods, other pain medications, SSRI/SNRI/tricyclics, and anxiolytics/sedatives/hypnotics. The PT group had the highest rates for NSAIDs, muscle relaxant, and oral steroids.
The public appears to agree with the scientific literature, as the Consumer Reports Health Ratings Center Survey (April 2009) revealed that chiropractic was the most satisfying treatment available for back pain.
Many studies have been published that examine manual therapies for the treatment of neck pain. The most recent high-quality study published found that for acute and sub-acute neck pain, spinal manipulation and exercise are more effective than medication in both the short and long term (See reference 5). Indeed, most studies that have examined spinal treatments for neck pain have reached similar conclusions, and in 2010 a high-quality systematic review concluded that spine manipulation or mobilization can provide immediate or short-term improvement in pain and function (See reference 6).
As it was for back pain treatment, the public appears to agree with the scientific literature regarding chiropractic neck pain treatment; the Consumer Reports Overview of Alternative Therapies (July 2011) revealed that chiropractic was considered more effective than all other neck-pain treatments.
A 2011 systematic review concluded that chiropractic therapies might be as effective as some commonly used medications for the prevention of migraine headaches (See reference 7). In addition, a unique subgroup of headaches caused by joint irritation in the neck (cervicogenic headache), also appear to respond well to manual therapies like chiropractic (See reference 8). The Consumer Reports Overview of Alternative Therapies (July 2011) indicated that the public considers chiropractic one of the top three most effective treatments for headaches and the highest rated drug-free approach to headache treatment.
Lumbar Disc Herniations and Radiculopathies
Combined with an active self-care program, many chronic pain patients find great benefit from ‘maintenance’ (or more accurately, ‘supportive or wellness’) care. A medical doctor/researcher has recently published the results of a high-quality study that examines long-term spinal manipulation in patients with chronic low back pain. The study found that “maintenance spinal manipulation” every 2 weeks obtains improved long-term benefits (See reference 14).
