Chiropractic is not a treatment of any specific condition, but rather a method of removing interference to your nervous system so your body can heal and function more optimally. Some conditions that are listed below are examples of chiropractic’s success in helping the body recover.

Arm Pain/Cervical Disc Herniation

Chiropractic treatment of cervical radiculopathy caused by a herniated cervical disc.
Brouillette DL, Gurske, DT. Journal of Manipulative and Physiologic Therapeutics, Feb 1994; 17(2): 119-123.

This is the case study of a 60-year-old woman with MRI documented herniated cervical disc. Symptoms included deep, constant, burning ache in the left arm, and severe neck and left shoulder pain. Under chiropractic care the patient’s pain and numbness disappeared and her grip-strength returned to normal within 5 months.

Athletic Performance

Chiropractic effects on athletic ability.
Lauro A. Mouch B. Chiropractic: The Journal of Chiropractic Research and Clinical Investigation. 1991; 6:84-87.

Fifty athletes involved in various activities including football, volleyball, track, cross-country running, weightlifting, body building, rugby and aerobic dancing were tested. They were divided into two groups.

One group received chiropractic adjustments, the other served as controls. Eleven tests were used to measure aspects of athletic ability including: agility, balance, kinesthetic perception, power, and reaction time. After 6 weeks, the control group and chiropractic group were examined.

The control group exhibited minor improvement in eight of the 11 tests (only two were statistically significant) while the chiropractic group improved significantly in all 11 tests (eight were statistically significant).

In a hand reaction test measuring the speed of reaction with the hand in response to a visual stimulus (reaction time), the control group exhibited less than a 1% response while the chiropractic group exhibited more than an 18% response after 6 weeks. After 12 weeks the chiropractic group exhibited more than 30% improvement in reaction time.

Back Pain

Chronic spinal pain – a randomized clinical trial comparing medication, acupuncture and spinal manipulation.
Giles LGF, Muller R. Spine 2003;28:1490-1503.

Three groups of patients with back pain were given a nine week course of care using medicine, acupuncture or chiropractic care. The results showed a significantly higher number of satisfied chiropractic patients.

Conservative treatment of acute and chronic nonspecific low-back pain. Van Tulder MW, Koes BW, Bouter LM Spine 1997;22:2128-2156.

This study reported that there is “strong evidence of the effectiveness of manipulation for patients with chronic low-back pain.”

Bed Wetting

Chiropractic management of primary nocturnal enuresis.
Reed WR, Beavers S, Reddy SK, Kern G.J Manipulative Physiol Ther Vol. 17, No. 9 Nov/Dec 1994.

This was a controlled clinical trial of 46 enuretic (bedwetting) children that were placed under chiropractic care. The children were under care for a 10 week period preceded by and followed by a 2 week no treatment period. The 46 children were divided into two groups: 31 received chiropractic care and 15 were in the control group. At the end of the study, 25% of the treatment-group children had 50% or more reduction in the wet night frequency from baseline to post-treatment while none among the control group had such reduction.

Carpal Tunnel / Arm / Hand Pain

Comparative efficacy of conservative medical and chiropractic treatments for carpal tunnel syndrome: a randomized clinical trial.
Davis PT, Hulbert JR, Kassak KM, et al. Journal of Manipulative and Physiological Therapeutics, June 1998, vol.21/no.5, pp317-26.

This study showed that chiropractic was as effective as medical treatment in reducing symptoms of CTS (carpal tunnel syndrome).

Cervical (Neck) Pain

Chronic spinal pain syndromes: a clinical pilot trial comparing acupuncture, a nonsteroidal anti-inflammatory drug (NSAID), and spinal manipulation. Giles LG, Muller R. J Manipulative Physiol Ther July/August 1999:22(6), pp.376-81.

Seventy seven patients were divided into three groups. One group received needle acupuncture, one group an NSAID and one group chiropractic care.

They were followed up after 30 days. Spinal care was the only intervention to achieve a statistically significant improvement. Patients receiving chiropractic care demonstrated a 30.7% reduction in Oswestry scores and a 25% reduction in neck disability index scores, a 50% reduction for low back pain, 46% reduction for upper back pain and 33% reduction for neck pain. Acupuncture and NSAIDS provided no significant improvement.

Chronic Fatigue Syndrome / Fibromyalgia

Upper cervical management of primary fibromyalgia and chronic fatigue syndrome cases.
Amalu WC. Today’s Chiropractic May/June 2000 Pp.76-86.

This paper discusses 23 successive cases (5 male, 18 female from 11 to 76 years of age) of primary fibromyalgia and chronic fatigue syndrome suffering from 2 to 35 years.

Total chiropractic visits ranged from 20 to 48. All patients reported maintaining their improvements at 1 to 1 ½ years or more of follow up. After care every patient was able to resume normal activities including full time work.

The author writes:

“Improvement in symptoms of 92-100% was achieved in both these syndromes…A causal relationship between biomechanical faults in the upper cervical spine, abnormal central neurophysiologic processing and subsequent peripheral neuropathophysiology, is suggested as the possible genesis of these two syndromes.”


The short-term effect of spinal manipulation in the treatment of infantile colic: a randomized controlled clinical trial with a blinded observer. Wiberg JMM, Nordsteen J, Nilsson N. Journal of Manipulative and Physiological Therapeutics. October 1999; Vol. 22, No. 8, pp. 517-522.

This is a randomized controlled trial that took place in a private chiropractic practice and the National Health Service’s health visitor nurses in a suburb of Copenhagen, Denmark.

One group of infants received spinal care for 2 weeks, the other was treated with the drug Dimethicone TM for 2 weeks. Changes in daily hours of crying were recorded in a colic diary.

Hours of crying reduced by 1 hour in the Dimethicone group compared with 2.4 hours in the chiropractic group by day 4-7. On days 8 through 11, crying was reduced by 1 hour for the Dimethicone group, compared with 2.7 hours in the chiropractic group.

In the 12 days of the study, the children under chiropractic care had a 67% reduction in crying while the group treated with drugs had a 38% reduction in crying. The mean number of adjustments given during the two-week study was 3.8.

Disc Herniation

Low force chiropractic care of two patients with sciatic neuropathy and lumbar disc herniation.
Richards GL et al. Am J Chiro Med Mar 1990;3(1):25-32

Two patients with sciatic neuropathy and confirmed disc herniation received chiropractic care. A follow-up CAT scan in the first patient revealed complete absence of disc herniation. A follow up scan in the second case revealed the continued presence of a silent disc bulge at the L3-4 level and partial decrease in a herniation at the L4-5 level. The bulge appeared to have shifted away from the nerve root. Both patients’ pain levels decreased from severe to minimal as they regained the ability to stand, sit and walk for longer periods without discomfort and lifting also became easier. They were able to return to full time work capacity at three and nine months respectively.

Dysmenorrhea (PMS)

A chiropractic approach to the treatment of dysmenorrhea.
Liebl NA, Butler LM Journal of Manipulative and Physiological Therapeutics, 1990; 13:101-106.

This is the study of a patient suffering from monthly menstrual cramps since the onset of menses which intensified after the birth of her child, 4 years prior, (eight painful days a month). The patient received 19 adjustments over a two month period, approximately twice per week for the first two months and once a week for the last month. Patient was adjusted in the sacroiliac, upper lumbar, mid-thoracic and upper cervical areas. Some cranial adjusting was done in some sessions.

“The average number of recordings showing pain in the baseline phase was 8 per month compared to an average of 2.25 episodes per month in the treatment phase.” Pain was over 1/3 lessened.

Ear Infections

The role of the chiropractic adjustment in the care and treatment of 332 children with otitis media.
Fallon, JM. Journal of Clinical Chiropractic Pediatrics Oct 1997, 2(2):167-183.

311 of the 332 had a history of prior antibiotic use. 53.7% of the children had their first bout of otitis media between the ages of 6 months and 1 year and a total of 69.9% of the subjects in the study had their first bout of OM under a year of age. This is consistent with the findings of others.

The children were 27-days-old to five-years-old. The average number of adjustments administered by types of otitis media were as follows: acute otitis media (127 children) 4 adjustments; chronic/serous otitis media (104 children) 5 adjustments; for mixed type of bilateral otitis media (10 children) 5.3 adjustments; where no otitis was initially detected (74 children) 5.88 adjustments. The number of days it took to normalize the otoscopic examination was for acute 6.67, chronic/serous 8.57 and mixed 8.3. The number of days it took to normalize the tympanographic examination was acute 8.35, chronic/serous 10.18 and mixed 10.9 days. The overall recurrence rate over a six month period from initial presentation in the office was for acute 11.02%, chronic/serous 16.34%, for mixed 30% and for none present 17.56%.


The effectiveness of chiropractic management of fibromyalgia patients: a pilot study.
Blunt KL, Rajwani MH, and Guerriero RC. J Manipulative Physiological Therapy; 1997: 20(6):389-99.

Twenty-one rheumatology patients aged 25-70 suffering from fibromyalgia (muscular pain characterized by muscular tautness/stiffness, well-defined tender/trigger points, numbness, tingling, and pain) were studied to demonstrate chiropractic’s effect on this condition.

Chiropractic care consisted of 4 weeks of spinal care plus soft tissue and passive stretching at the chiropractors’ discretion. Chiropractic management improved patients’ cervical and lumbar ranges of motion, straight leg raise and reported pain levels.


A randomized controlled trial of chiropractic spinal manipulative therapy for migraine.
Tuchin PJ, Pollard H, Bonello R. Journal of Manipulative and Physiological Therapeutics Feb. 2000:23(2), PP.91-5.

This was a six month study of 127 migraine sufferers half of whom had diversified chiropractic adjustments. The other half was the control group. Subjects in the manipulation group demonstrated statistically significant improvement in migraine frequency, headache duration, disability and medication use. 22% of those undergoing chiropractic care reported more than 90% reduction in migraines after two months. About 50% reported significant improvement in severity of migraine episodes.

The effect of spinal manipulation in the treatment of cervicogenic headache. Nilsson N, Christensen HW, Hartvigsen J. Journal of Manipulative and Physiological Therapeutics, 1997; 20:326-330.

This is a randomized controlled trial performed at the University of Odense, Denmark by chiropractors and medical doctors.

Of 53 patients suffering from frequent headaches, 28 received high-velocity, low-amplitude cervical manipulation twice a week for three weeks. The remaining 25 received low-level laser in the upper cervical region and deep friction massage in the lower cervical/upper thoracic region, also twice a week for three weeks.

The use of analgesics decreased by 36% in the manipulation group, but was unchanged in the soft-tissue group; this difference was statistically significant. The number of headache hours per day decreased by 69% in the manipulation group compared with 37% in the soft-tissue group; this was significant. Finally, the headache intensity per episode decreased by 36% in the manipulation group, compared with 17% in the soft-tissue group; this was significant.

High Blood Pressure

Preliminary study of blood pressure changes in normotensive subjects undergoing chiropractic care.
McKnight ME, DeBoer KF, Journal of Manipulative and Physiological Therapeutics,1988; 11:261-266.

Seventy-five people were tested after specific chiropractic cervical adjustments.

Both systolic and diastolic blood pressure decreased significantly in the adjusted group. No significant changes occurred in the control group.

In those with the highest pre-treatment blood pressures, the treatment effect was greatest, indicating that the effectiveness in hypertensives may be even more significant.

Effects of chiropractic treatment on blood pressure and anxiety: a randomized, controlled trial. Yates RG, Lamping DL, Abram NL, Wright C. Journal of Manipulative and Physiological Therapeutics, 1988; 11(6):484-8.

In this patient-blinded, assessor-blinded, placebo-controlled study, the authors state that the data “lend support to the hypothesis that chiropractic manipulation of the thoracic spine significantly reduces blood pressure in patients with elevated blood pressure.”

Both systolic and diastolic blood pressure decreased significantly in the adjusted group. Adjustments were delivered to segments T-1 to T-5 of the 21 patients in the group adjusted. No significant changes occurred in the placebo or control groups.

Knee Pain

Conservative lower back treatment reduces inhibition in knee extensor muscles: a randomized controlled trial.
Suter E, McMorland G, Herzog W, et al. Journal of Manipulative and Physiological Therapeutics Feb 2000:23(2), pp.76-80.

Twenty-eight patients with anterior knee pain (AKP) were randomly assigned to receive chiropractic care or no care (control group). The chiropractic care was designed to correct SI-joint dysfunction. Before and after care, knee-extensor moments, muscle inhibition (MI), and muscle activation during full effort and isometric knee extensions were measured. Patients showed substantial MI in both legs. Functional assessment revealed SI-joint dysfunction in all subjects (23 symptomatic and 5 asymptomatic). After care, a significant decrease in MI of 7.5% was observed in the involved legs of the adjusted group. MI did not change in the contralateral legs of the treatment group or the involved and contralateral legs of the control group. The results of this study suggest that SI-joint manipulation reduces knee-extensor MI. Spinal manipulation may possibly be an effective treatment of MI in the lower limb musculature.

The effects of chiropractic treatment on pregnancy and labor: a comprehensive study.
Fallon J. Proceedings of the world chiropractic congress. 1991; 24-31.

The hormonal changes that occur during pregnancy can change the shape of the spinal curves and overall posture which can affect organ systems. In this study Dr. Fallon describes her work with 65 women who received chiropractic care from at least the tenth week of pregnancy through labor and delivery. These women experienced mean labor times significantly reduced compared to controls. Women who were primagravidae (first pregnancy) who received chiropractic care averaged 24% shorter labor times than average for primagravidae women. Women who were multiparous (had had at least one child prior) averaged 39% shorter labor times versus controls.

It is a common observation that birthing seems to be more comfortable for women who were under chiropractic care during pregnancy. The chiropractic drug-less approach is ideally suited for pregnancy care.


Non-operative treatments for sciatica: a pilot study for a randomized clinical trial.
Bronfort G, Evans RL, Anderson AV et al. Journal of Manipulative and Physiological Therapeutics October 2000, Vol. 23 No. 8.

This is a prospective, observer-blinded, pilot randomized clinical trial of 20 patients aged 20-65 with low back-related leg pain. Patients were divided into three groups. One group was given medical care, one group chiropractic care and one group steroid injections. All groups showed substantial improvement at the end of the 12 week study.

Lack of effectiveness of bed rest for sciatica. Patrick CAJ, Vroomen MD, Marc CTFM, et al. The New England Journal of Medicine. 1999;340:418-423.

Many medical doctors prescribe bed rest for sciatica, yet according to the authors: “For low back pain, bed rest has traditionally been considered effective, although there are few objective data to support this view and in recent years evidence of the ineffectiveness of bed rest for low back pain has accumulated…bed rest continues to be widely used to treat sciatica.”

From the conclusion: “Among patients with symptoms and signs of a lumbosacral radicular syndrome, bed rest is not a more effective therapy than watchful waiting.”


TMJ (Jaw Joint)

Chiropractic care of a patient with temporomandibular disorder and atlas subluxation.
Alcantara J, Plaugher G, Klemp, DD, Salem C Journal of Manipulative and Physiological Therapeutics January 2002 marker Volume 25 marker Number 1

This is the case of a 41-year-old woman who sought care for complaints associated with a cervical subluxation (i.e., atlas) and TMD.

Her complaints began with a left ear infection that was medically treated with oral antibiotics. At the time of chiropractic consultation, complaints included pain at the TMJ (bilaterally), “ear pain,” tinnitus, vertigo, altered or decreased hearing acuity, a sensation of pressure or fullness in both ears and headaches, which she characterized as a throbbing or pounding. She also had a 22-year history of migraine headaches, which were partially relieved by previous chiropractic care. She did not take her prescribed medications because of adverse reactions (i.e., gastric upset and vomiting).

She was referred to an eye, ear, nose, and throat specialist who diagnosed her with TMJ syndrome. She was referred to a dentist for a possible malocclusion. The dentist found no occlusal abnormalities. Medical recommendations were to apply local heat, reduce talking and yelling and change to a soft diet. The patient reported that her symptoms steadily worsened with these measures. Chiropractic care consisted of specific adjustments to the atlas subluxation resulting in improvement of the patient’s symptoms. By the third visit, she reported significantly greater improvement on the right than on the left side. By the fifth visit, the patient reported that the right ear was “perfectly fine.” With subsequent visits, she reported continuous improvement, with only the left ear sensation of fullness remaining. She reported complete relief of TMJ symptoms 2 1/2 months (9 visits) from the onset of chiropractic care. In addition, she reported a decrease in the frequency and severity of her headaches. Before chiropractic care, she related a frequency of 1 to 2 migraine attacks per month. At 1-year follow-up she had experienced no headache symptoms for a period of 9 months. Her TMJ complaints had completely resolved.

Torticollis (Wry Neck)

Chiropractic adjustments and congenital torticollis with facial asymmetry: a case study.
Hyman C.A. International Chiropractors Association Review September/October 1996. Pages 41-45.

This is the case of a two-month-old female presented with obstetrical brachial plexus injury (Erb’s palsy) that had been under the care of several medical pediatricians without resolution. The condition showed complete resolution under chiropractic care without any complications or residual impairments.

Congenital muscular torticollis: a review, case study, and proposed protocol for chiropractic management. Colin N. Top Clin Chiro (1998); 5(3):27-33.

A case study of a 7-month-old infant who had been medically diagnosed with the disorder as birth-trauma related. Summary: Six sessions of chiropractic management involving low force adjusting and gentle myofascial release work were administered based on clinical mechanical findings derived form an apparent right hand and right leg dominance in the child. The child had not previously responded to several weeks of physical therapy. Following chiropractic care, the case completely resolved. The response was sustained at one year follow-up.


Cervicogenic vertigo and chiropractic, managing a single case – a case report.
Cagle P, Journal of the American Chiropractic Association May 1995 p.83-84.

Case study of a 71 year-old woman who had “sudden onset of severe disabling vertigo.”

The patient tried standard medical care for almost a year with very little relief. Then, she went for chiropractic care. The cervical adjustments she received resolved the vertigo.

This short paper includes a well-written section on the causes of vertigo, and discusses the theories of cervicogenic vertigo’s causes.


A multiple parameter assessment of whiplash injury patients undergoing subluxation based chiropractic care: a retrospective study.
McCoy HG and McCoy M. Journal of Vertebral Subluxation Research Vol 1, No 3, 1997 Pp. 51-61.

From the Abstract:

A retrospective study was conducted of 57 subjects who had experienced an acceleration/deceleration (whiplash) injury… With subluxation-based chiropractic care, the subject population showed significant increases in cervical flexion and extension, muscle strength, and a decrease in the neck pain disability index. Atlas/axis and Jackson’s angles varied inversely from presentation to MCI (maximum chiropractic improvement)…longer durations of care were correlated with the lower ratios (fewer adjustments/week), while shorter durations of care to reach MCI were correlated to higher ratios (average adjustments/week).
