Neurologic complications following chiropractic manipulation: a survey of California neurologists.
To obtain an estimate of how often practicing neurologists in California encounter unexpected strokes, myelopathies, or radiculopathies following chiropractic manipulation, we surveyed each member of the American Academy of Neurology in California and inquired about the number of patients evaluated over the preceding 2 years who suffered a neurologic complication within 24 hours of chiropractic manipulation. Four hundred eighty-six neurologists were surveyed, 177 responded; 55 strokes, 16 myelopathies, and 30 radiculopathies were reported. Patients were between the ages of 21 and 60, and the majority experienced complications following cervical manipulation. Most of the patients continued to have persistent neurologic deficits 3 months after the onset, and about one-half had marked or severe deficits. Nearly all of the strokes involved the posterior circulation and almost one-half were angiographically proven. Patients, physicians, and chiropractors should be aware of the risk of neurologic complications associated with chiropractic manipulation.

Brain stem infarction due to chiropractic manipulation of the cervical spine.
A case of brain stem infarction after chiropractic manipulation of the cervical spine is presented. Proposed mechanisms and sites of possible arterial injury are discussed. A diagnosis of vertebral artery occlusion was made using conventional brachial angiography. Digital intravenous angiography, a relatively new and less invasive vascular imaging technique which was used as an adjunct for evaluating the remainder of the cervicocephalic vessels, documented the vertebral occlusion. Chiropractic manipulation, which is increasing in popularity, may be a cause of potentially devastating neurologic disease.

The effect of chiropractic manipulation on salivary cortisol levels.
BACKGROUND: The stress response in humans is a healthy response and is necessary for life. The effects of chiropractic manipulation (CM), if any, on stress are ill-defined. Cortisol has been used as an accurate measure of the stress response system in humans. Salivary cortisol is a noninvasive technique to accurately quantify biologically active cortisol. OBJECTIVE: To determine whether basal salivary cortisol levels can be properly detected and whether CM has any direct effect on basal salivary cortisol levels in humans. METHODS: Subjects were adult male students attending a chiropractic college. Salivary samples were collected for 5 weeks. During Week 1, samples were collected by the students at home upon waking. During Weeks 2 through 5, home samples were collected upon waking and were followed by an additional time course of samples collected in a laboratory setting before and after CM. Salivary cortisol was measured by enzyme-linked immunoassay. RESULTS: Chiropractic manipulative therapy did not significantly change basal salivary cortisol levels. The time course of acute changes to cortisol levels was independent of testing week and group. A decrease in salivary cortisol was detected over time on each trial testing day. Overall, cortisol levels significantly decreased from the time of the home samples until the pretreatment laboratory measurement (P <.05). Cortisol levels subsequently decreased from pretreatment to 15 minutes after treatment (P <.05). After treatment, there were progressive decreases in cortisol levels from the 15- and 30-minute time points to the 60-minute time point (P <.05). CONCLUSION: The results of this pilot study suggest that there is no effect of CM on salivary cortisol levels in asymptomatic subjects. As such, we conclude that neither the anticipation of CM nor the spinal manipulative procedure itself induces a state of stress or anxiety.

Chiropractic sympathectomy: carotid artery dissection with oculosympathetic palsy after chiropractic manipulation of the neck.
The clinical association between carotid artery dissection and oculosympathetic palsy is well-known. However, the occurrence of this combination with chiropractic manipulation of the cervical neck is rare. We describe the case of a 54-year-old Caucasian American male who underwent cervical manipulation for neck pain. The following day he noticed drooping of his left eyelid, with an unequal pupil size. Imaging later confirmed carotid artery dissection. Only three previous cases (one from the United States ), of an association between carotid artery dissection and chiropractic sympathectomy (oculosympathetic palsy after chiropractic manipulation of the neck) have been reported. Pictures of the oculosympathetic palsy, computed tomography of the head and magnetic resonance imaging of the dissection are presented.

Chiropractic manipulation and acute neck pain: a review of the evidence.
OBJECTIVE: The aim of this study was to review the chiropractic and medical literature in an effort to determine the extent of current evidence supporting the use of chiropractic manipulation for the treatment of acute neck pain. METHODS: A literature search of the MEDLINE/PubMed and MANTIS (Manual Alternative and Natural Therapy Index System) databases, extending from 1966 to September 2003, was conducted. Search terms included "cervical," "neck," "chiropractic," "neck pain," "patient satisfaction," and "manipulation." The inclusion criteria for article selection were studies dealing with the treatment of neck pain by means of chiropractic manipulation, regardless of the number of subjects involved or whether randomization was implemented. RESULTS: Two hundred sixty-seven citations were identified. Most were eliminated because they either did not specifically deal with the treatment of acute neck pain with manipulation or were not written in English. Less than 10 articles marginally dealt with the treatment of acute neck pain with cervical manipulation. Moreover, there has only been one randomized clinical trial published in the English language that specifically dealt with the treatment of acute neck pain by manipulation. Other studies involved patients with neck pain of a subacute or chronic nature or treated test subjects with mobilization techniques rather than manipulation. CONCLUSION: There has been scant investigative research into the treatment of acute neck pain with chiropractic manipulation. Consequently, more data are needed and appropriate studies should be initiated.

[Horner's syndrome in dissection of the carotid artery after chiropractic manipulation].
CASE REPORT: We report on a 37-year old patient with sudden onset of pain of the right scalp and an ipsilateral small pupil, presenting five weeks after chiropractic manipulation of the neck. METHODS/RESULTS: Pharmacologic pupil testing showed a postganglionic Horner's syndrome on the right side. Magnetic resonance angiography confirmed the diagnosis of a dissection of the right internal carotid artery at a subacute stage. CONCLUSION: There appears to be a causal relationship between carotid artery dissection and the chiropractic manipulation of the cervical spine. Ophthalmological signs played the key role in detecting this complication.

Chiropractic manipulation affects the difference between arterial systolic blood pressures on the left and right in normotensive subjects.
OBJECTIVE: The purpose of this study is to determine whether chiropractic manipulation is associated with any measurable changes in the difference between the arterial blood pressures on the left and right before and after treatment in normotensive subjects. METHODS: A nonrandomized, matched pair, controlled clinical trial, with the treatment (manipulation) group and control (resting) group matched for age and sex, was performed in chiropractic student clinics in London, UK. The treatment group consisted of 35 new patients presenting to a single student chiropractor between the start of April 2003 and the end of August 2003. The control group consisted of 35 nonpatients matched for sex and age. The intervention was chiropractic manipulation. Preintervention and postintervention systolic and diastolic blood pressures were recorded in both arms through the use of a digital oscillometric sphygmomanometer. RESULTS: A significant difference was found between the pre- and posttreatment blood pressure differences for systolic pressures (P = .01), but no significant difference was found in either set of control data or the treatment diastolic values. A significant difference was also found between the treatment and control group's preintervention systolic differences (P = .002), but not between the groups at any other time. CONCLUSION: Chiropractic treatment appears to have an effect on the difference in systolic blood pressure between the arms, which is not shown in the control group or the diastolic treatment group values. This may be attributable to a difference between the 2 groups' preintervention systolic values; however, there was no significant difference between the 2 groups after intervention.

A comparison of active and simulated chiropractic manipulation as adjunctive treatment for childhood asthma.
BACKGROUND: Chiropractic spinal manipulation has been reported to be of benefit in nonmusculoskeletal conditions, including asthma. METHODS: We conducted a randomized, controlled trial of chiropractic spinal manipulation for children with mild or moderate asthma. After a three-week base-line evaluation period, 91 children who had continuing symptoms of asthma despite usual medical therapy were randomly assigned to receive either active or simulated chiropractic manipulation for four months. None had previously received chiropractic care. Each subject was treated by 1 of 11 participating chiropractors, selected by the family according to location. The primary outcome measure was the change from base line in the peak expiratory flow, measured in the morning, before the use of a bronchodilator, at two and four months. Except for the treating chiropractor and one investigator (who was not involved in assessing outcomes), all participants remained fully blinded to treatment assignment throughout the study. RESULTS: Eighty children (38 in the active-treatment group and 42 in the simulated-treatment group) had outcome data that could be evaluated. There were small increases (7 to 12 liters per minute) in peak expiratory flow in the morning and the evening in both treatment groups, with no significant differences between the groups in the degree of change from base line (morning peak expiratory flow, P=0.49 at two months and P=0.82 at four months). Symptoms of asthma and use of 3-agonists decreased and the quality of life increased in both groups, with no significant differences between the groups. There were no significant changes in spirometric measurements or airway responsiveness. CONCLUSIONS: In children with mild or moderate asthma, the addition of chiropractic spinal manipulation to usual medical care provided no benefit.

Hyperhomocysteinemia: a potential risk factor for cervical artery dissection following chiropractic manipulation of the cervical spine.
Despite the increasing incidence of cervical artery dissection (CAD) due to chiropractic manipulation of the cervical spine, risk factors predisposing to vascular damage are still unknown. In the present study we measured fasting total plasma homocysteine (tHcy) concentration in 4 subjects with manipulation-related CAD selected from a larger series of patients with spontaneous dissection of the neck arteries (sCAD) and in a group of 36 control subjects. C677T MTHFR genotypes and 844ins68bp CBS genotypes were also determined. Median tHcy levels were significantly (P = 0.002) higher in patients with manipulation-related CAD (18.2 micromol/l, range 14.3 to 30.0) compared with controls (8.9 micromol/l, range 5 to 17.3) and not significantly different (P = 0.129) from those observed in patients with sCAD (13.9 micromol/l, range 7 to 32.8). No significant difference in the distribution of genotypes was observed in the three groups. Hyperhomocysteinemia may represent a potential risk factor for manipulation-related CAD, leading to structural abnormalities of the arterial wall and increasing the susceptibility to mechanical stress.

A comparison of physical therapy, chiropractic manipulation, and provision of an educational booklet for the treatment of patients with low back pain.
BACKGROUND AND METHODS: There are few data on the relative effectiveness and costs of treatments for low back pain. We randomly assigned 321 adults with low back pain that persisted for seven days after a primary care visit to the McKenzie method of physical therapy, chiropractic manipulation, or a minimal intervention (provision of an educational booklet). Patients with sciatica were excluded. Physical therapy or chiropractic manipulation was provided for one month (the number of visits was determined by the practitioner but was limited to a maximum of nine); patients were followed for a total of two years. The bothersomeness of symptoms was measured on an 11-point scale, and the level of dysfunction was measured on the 24-point Roland Disability Scale. RESULTS: After adjustment for base-line differences, the chiropractic group had less severe symptoms than the booklet group at four weeks (P=0.02), and there was a trend toward less severe symptoms in the physical therapy group (P=0.06). However, these differences were small and not significant after transformations of the data to adjust for their non-normal distribution. Differences in the extent of dysfunction among the groups were small and approached significance only at one year, with greater dysfunction in the booklet group than in the other two groups (P=0.05). For all outcomes, there were no significant differences between the physical-therapy and chiropractic groups and no significant differences among the groups in the numbers of days of reduced activity or missed work or in recurrences of back pain. About 75 percent of the subjects in the therapy groups rated their care as very good or excellent, as compared with about 30 percent of the subjects in the booklet group (P<0.001). Over a two-year period, the mean costs of care were $437 for the physical-therapy group, $429 for the chiropractic group, and $153 for the booklet group. CONCLUSIONS: For patients with low back pain, the McKenzie method of physical therapy and chiropractic manipulation had similar effects and costs, and patients receiving these treatments had only marginally better outcomes than those receiving the minimal intervention of an educational booklet. Whether the limited benefits of these treatments are worth the additional costs is open to question.

Vertebral artery dissection and cerebellar infarction following chiropractic manipulation.
Vertebral artery dissection (VAD) associated with chiropractic cervical manipulation is a rare but potentially disabling condition. In this report, we present a young patient manifesting with repeated vertigo. Owing to the initial misdiagnosis, the patient later developed cerebellar stroke with inability to stand or walk. Vertigo and disequilibrium are the usual presenting symptoms of this condition, which can result from inner ear or vestibular nerve dysfunction, vertebrobasilar insufficiency, and even lethal cerebellar infarction or haemorrhage; these last two, although rarely seen in young adults, can be caused by traumatic or spontaneous arterial injury, including injury secondary to chiropractic cervical manipulation. A number of cases of VAD associated with chiropractic cervical manipulation have been reported, but rarely in the emergency medicine literature. We present a case of this rare occurrence, and discuss the diagnostic pitfalls.

A case of subdural hematoma and temporal bone fracture as complications of chiropractic manipulation.
We present a case of subdural hematoma and temporal bone fracture as a complication of chiropractic manipulation. Subdural hematoma in the elderly may follow insignificant, often forgotten, trauma and may develop slowly and progress. Our patient presented with a complaint of headache three days after forceful chiropractic manipulation, but denied any history of trauma. Computed tomography confirmed the presence of a subdural hematoma and a temporal bone fracture and the patient underwent successful surgical treatment. Our experience identifies a previously unreported mechanism of injury in patients with subdural hematoma presenting to the emergency department with a complaint of headache.

An evaluation of chiropractic manipulation as a treatment of hyperactivity in children.
The principle aim of this study was to determine the effectiveness of chiropractic manipulative therapy in the treatment of children with hyperactivity. Using blinds between investigators and a single subject research design, the investigators evaluated the effectiveness of the treatment for reducing activity levels of hyperactive children. Data collection included independent evaluations of behavior using a unique wrist-watch type device to mechanically measure activity while the children completed tasks simulating school-work. Further evaluations included electrodermal tests to measure autonomic nervous system activity. Chiropractic clinical evaluations to measure improvement in spinal biomechanics were also completed. Placebo care was given prior to chiropractic intervention. Data were analyzed visually and using nonparametric statistical methods. Five of seven children showed improvement in mean behavioral scores from placebo care to treatment. Four of seven showed improvement in arousal levels, and the improvement in the group as a whole was highly significant (p = 0.009). Agreement between tests was also high in this study. For all seven children, three of the four principal tests used to detect improvement were in agreement either positively or negatively (parent ratings of activity, motion recorder scores, electrodermal measures, and X-rays of spinal distortions). While the behavioral improvement taken alone can only be considered suggestive, the strong interest agreement can be taken as more impressive evidence that the majority of the children in this study did, in fact, improve under specific chiropractic care. The results of this study, then, are not conclusive, however, they do suggest that chiropractic manipulation has the potential to become an important nondrug intervention for children with hyperactivity. Further investigation in this area is certainly warranted.
