The Effectiveness of Chiropractic Care
Numerous literature reviews and meta-analysies have been conducted concerning patient satisfaction, efficacy, and cost effectiveness of chiropractic care. Chiropractic care has been found to be effective in more than just low back and neck pain!
Acute Low-Back Pain
- In 1994, the Agency for Health Care Policy and Research (AHCPR) published Clinical Practice Guideline
14–Acute Low Back Problems in Adults. In the guideline, the acute low back pain was defined, treatments were evaluated, and recommendations regarding the efficacy of those treatments were discussed. Spinal manipulation proved to be one of the safest and most efficacious forms of treatment. It offers both pain relief and functional improvement. The AHCPR made history with its conclusion that “spinal manipulation hastens recovery from acute low back pain and recommends that this therapy be used in combination with or as an alternative to non-steroidal anti-inflammatories.”
- In 1992, the Annals of Internal Medicine published a review of literature conducted by medical doctors and chiropractic physicians at RAND and UCLA Schools of Medicine. This review of over 25 controlled studies and 9 meta-analysies addressed chiropractic treatment of low-back pain. The conclusion made was that “spinal manipulation hastens recovery form uncomplicated low-back pain.”
Chronic Low-Back Pain
- In 1997, three researchers funded by the Dutch Health Insurance Board in the Netherlands retrieved and evaluated 48 randomized controlled trials conducted worldwide concerning the treatment of both acute and chronic low-back pain.Evidence strongly suggests that spinal manipulation for chronic low-back pain can be rather effective.
General Low-Back Pain
- In 1999, Bronfort conducted a systematic review of literature concerning the efficacy of chiropractic for low-back pain. He found that spinal manipulative therapy has a short-term effect in cases of acute low-back pain.Compared with placebo and other commonly used therapies by general medical practitioners, spinal manipulation and mobilization are also effective for chronic low-back pain.
- A 1993 study by the Ontario Ministry of Health concluded that spinal manipulation is the most effective treatment for low-back pain. They also concluded that spinal manipulation is safer than medical management of low-back pain.
- The Foundation for Chiropractic Education and Research conducted a 1998 study of 10,652 workers’ mompensation cases in Florida. The study reported that back injuries treated by chiropractors were less likely to quire hospitalization or to develop compensable injuries (injuries resulting in lost time from work and thus compensation) than those who were treated by medical doctors or osteopaths.
- In 1990, T.W. Meade of the British Medical Journal reported that after two years of patient monitoring, “for patients with low-back pain in whom manipulation is not contraindicated, chiropractic almost certainly confers worthwhile, long-term benefit in comparison with hospital outpatient management.”
- Following a 1993 study, researchers at the Back Pain Clinic at the Royal University Hospital in Saskatchewan concluded that side posture adjustments for patients with lumbar intervertebral disc herniation is both safe and effective.
- A new anatomical discovery was reported in 1998 by Hack: connective tissue joining the tough, protective outer layer of the brain and spinal cord to the neck muscles. Therefore, a cause-and-effect relationship exists between cervical spine dysfunction and headaches. Spinal manipulation can decrease muscle tension aiding in pain reduction via reducing “potential forces exerted on the dura” from the muscle-dura connection.
- In 1997, doctors in Denmark found manipulation to have a “significant positive effect” on intensity and duration of cervicogenic headaches compared to soft tissue therapy.
- A study comparing amitriptyline (pain medication) to manipulation in the treatment of tension headaches found manipulation rather successful. The manipulation group showed a 32% reduction in headache intensity, a 42% reduction in headache frequency, a 30% reduction in OTC (over-the-counter) medication usage, and a 16% improvement in general health status. The amitriptyline group showed no improvement or slight worsening of symptoms.
- In 1998, Mitchell, O’Sullivan, and Humphreys discovered the need for manual therapy of the muscles and ligaments of the neck post-MVA (motor vehicle accident) due to their attachment to the skull. Treatment of the damaged ligaments helped eliminate cervicogenic headaches.
- A 1997 study conducted by Blunt, Rajwani, and Guerriero concluded that chiropractic treatment of fibromyalgia resulted in the significant improvement in flexibility and a decrease in pain. The authors did, however, note that a multidisciplinary regime including chiropractic care for the treatment of fibromyalgia was recommended.
Carpal Tunnel Syndrome
- Chiropractic treatment for carpal tunnel syndrome (CTS) was compared to nonsurgical medical treatment in a study preformed by Davis in 1998. The chiropractic group used wrist supports, manipulation and ultrasound; the medical group used ibuprofen and wrist supports. Both groups showed improvements; however, the authors noted that chiropractic treatment should be considered for those who are not able to tolerate ibuprofen.
- A 1996 study conducted by RAND and several academic institutions conducted a review of literature on the treatment of neck pain. Manipulation was found more effective than mobilization or physical therapy in the treatment of subacute and chronic neck pain.
- Two randomized clinical trials were conducted in the Netherlands comparing the treatment of chronic back and neck complaints. Faster and greater improvement was shown in the spinal manipulation group compared to those receiving a placebo, physiotherapy, or treatment by a general practitioner.
- Verhoef, Page, and Waddell concluded in 1997 that “patients suffering from back and/or neck complaints experienced chiropractic care as an effective means of resolving or ameliorating pain” coupled with overall functional improvements.
- Klougart, Nilsson, and Jacobsen conducted a 1989 prospective study of 316 cases of infantile colic.The infants (average age of 5.7 weeks) all had moderate to severe colic but were otherwise healthy. The authors discovered that 94% of the infants appeared to be aided by chiropractic treatment “within 14 days from the start of treatment.” This improvement was manifested in both a reduction in both the length and number of colic periods which were not attributed to “the natural cessation of colic.”
- In 1999, Wilberg, Nordsteen, and Nilsson conducted a study on infantile colic. They found that spinal manipulation had a positive short-lived effect on infantile colic. The researchers also randomly placed infants in two groups for a two-week period of time: chiropractic treatment or dimethicone medication. Several dimethicone subjects dropped out of the study due to a worsening of symptoms. However, not only did the chiropractic study group retain all their subjects, but they also exhibited a “reduction of 67% on day 12” of daily hours with colic. The dimethicone group only had a 38% reduction in daily hours with colic.
- Respected researchers Triano, McGregor, and Skogsberg wrote an opinion article in 1997 concerning the use of chiropractic manipulation in lumbar rehabilitation. Chiropractic care is “a valuable tool” that helps to ease patients into necessary rehabilitative procedures, relieve symptoms, and restore patients’ confidence in movement and flexibility. It also helps to prevent chronicity.
