"Doctors of chiropractic reported that approximately 12% of their patients were under the age of 16. The largest group of patients, 37% was in the 17 - 44 age group, with the 45-64 year old group encompassing 34% of patients." ~ Canadian Chiropractic Association

General Lower-Back Pain
Several studies have been conducted to determine the efficacy of spinal manipulation as a treatment for lower-back pain in general. One of these involved three chiropractic colleges in California, where researchers reported that "the trend for spinal manipulation to produce better results than any form of treatment to which it was compared was consistent and strong." For 86% of the outcomes, spinal manipulation was more effective than any other treatment rendered for lower-back pain.
Additional studies conducted both in and out of the United States yielded similar results, where patients reportedly recovered at a more rapid rate, had fewer relapses, and gained a new sense of confidence in their movement. Still more investigations have been conducted on the effectiveness of chiropractic treatment for two sub-categories of lower-back pain: acute and chronic.
Acute Lower-Back Pain
A third study conducted by the Los Angeles College of Chiropractic and the University of Vermont was published in 1992. These researchers reported that spinal adjustment, when compared to other methods of treatment for acute lower-back pain (massage, corset, and TMS), proved to be a "superior," more effective treatment after three weeks of care.
Chronic Lower-Back Pain
Two similar studies conducted in Canada in 1985 (University Hospital in Saskatoon) and 1991 (University of Calgary), plus a third study conducted in Poland in 1986 (Silesian Medical School), produced results similar to the Dutch investigation.
The efficacy of chiropractic for neck pain has been well documented in numerous studies conducted in the United States, Canada, Wales, and the Netherlands. In a joint U.S./Canadian study published in 1996, researchers from UCLA, the West LA Veterans Affairs Medical Center, and two chiropractic colleges found that for some patients with sub-acute or chronic neck pain, spinal adjustment proved to be a more effective treatment than mobilization or physical therapy.
In a study conducted by the Canadian Memorial Chiropractic College in Toronto in 1997, researchers found spinal adjustments to improve neck mobility and decrease neck pain. An additional Canadian investigation published in 1997 by the University of Calgary found spinal adjustments to improve neck mobility and decrease neck pain in patients having back and/or neck complaints.
General practitioners in private practice at the Welsh National School of Medicine conducted a study of the efficacy of spinal adjustment in alleviating neck and shoulder pain. The results, published in 1983, indicated that pain and discomfort improved significantly after adjustment, as well as range of motion and flexibility of the affected areas.
A 1992 Netherlands study conducted by doctors of medicine and other professionals investigated different methods of treatment for patients with chronic back and neck pain. After 12 weeks of care, manual therapy (which consisted of adjustment and mobilization of the spine) had showed a "faster and larger improvement in physical functioning" relative to the other types of treatment such as massage, exercises, and physical therapy.
In a 1995 study conducted in Minnesota, the effectiveness of spinal adjustment relative to the administration of an antidepressant drug (amitriptyline) for patients with chronic tension-type headaches was investigated. The researchers included doctors of chiropractic, a doctor of medicine, and another professionals from Northwestern College of Chiropractic and the Pain Assessment and Rehabilitation Center, Ltd. They determined that, after four weeks of treatment, patients receiving spinal adjustment therapy experienced a continued lack of symptoms, whereas patients taking the medication returned to original, baseline conditions.
Another study, published in 1997 by doctors of medicine and doctors of chiropractic at the University of Odense and the Nordic Institute of Chiropractic and Clinical Biomechanics in Denmark, compared spinal adjustment and soft tissue therapy for the treatment of benign, chronic headaches. They found that both methods of therapy allowed for significant improvement, and there were no side effects or signs of worsening associated with either method.
Carpal Tunnel Syndrome (CTS)
One study, published in 1998 and conducted by researchers from the Northwestern College of Chiropractic in Minnesota, compared chiropractic treatment of CTS to conservative medical treatment. The chiropractic treatment included manipulation, ultrasound treatment, and wrist supports, while the medical group received an anti-inflammatory drug (ibuprofen) and wore wrist supports. They found that both methods of treatment proved to be equally effective and recommended that patients with CTS who are sensitive to medical side effects pursue chiropractic for treatment.
In 1997, a study was conducted by three Canadian chiropractors on the effectiveness of chiropractic care for patients with fibromyalgia. They reported significant improvement in flexibility and reduction of pain levels and recommended that this type of treatment be included along with medical treatments for this condition.
One study that documents the efficacy of chiropractic for treating infantile colic was conducted in 1989 by a doctor of medicine and doctors of chiropractic at the Anglo-European College of Chiropractic in Great Britain. Researchers reported that 94% of infants with colic appeared to be helped by spinal manipulation within 14 days of the start of treatment. The babies tended to have both fewer episodes of crying and shorter crying spells.
Another study, this one conducted in 1999 in Denmark, investigated two infant groups: one that was treated with spinal manipulation, and another that was treated with an over-the-counter antacid medication (dimethicone). After two weeks, the group treated with spinal manipulation exhibited a 67% drop in daily hours of crying, while the dimethicone group experienced a 38% drop.
