High-dose methylprednisolone prevents extensive sick leave after whiplash injury. A prospective, randomized, double-blind study.

STUDY DESIGN: A prospective, randomized, double-blind study comparing high-dose methylprednisolone with placebo. OBJECTIVES: To evaluate the efficacy of high-dose methylprednisolone when administered within 8 hours after whiplash injury. SUMMARY OF BACKGROUND DATA: Whiplash injury often results in chronic symptoms. The management of whiplash injuries is controversial, and pharmacologic therapy has received little evaluation. In recent reports, dysfunction of the central nervous system has been indicated in several cases. Methylprednisolone administered within 8 hours after the injury to patients with acute spinal cord injury has been demonstrated to improve the outcome. This procedure was also adopted in a randomized study of cases of whiplash injury in car accidents. METHODS: Forty patients, 22 men and 18 women with a mean age of 35 years (range, 19-65), were included in the study, 20 in each of two groups. They were treated for whiplash injury, which they had sustained in car accidents. The patients were enrolled if their diagnoses were complete and treatment had begun within 8 hours after injury. Disabling symptoms severe enough to prevent the patient from returning to work, number of sick days before and after injury, and sick-leave profile after injury were used as parameters for the evaluation of the effects of the treatment. Baseline demographic data were controlled for when statistical analysis had been performed. RESULTS: At the follow-up examination 6 months after initial treatment, there was a significant difference in disabling symptoms between the actively treated patients and the placebo group (P = 0.047), total number of sick days (P = 0.01), and sick-leave profile (P = 0.003). CONCLUSIONS: The results of this study indicate that acute treatment with high-dose methylprednisolone may be beneficial in preventing extensive sick leave after whiplash injury. However, the number of patients studied was small, and therefore further prospective, controlled studies are needed.

Road safety engineering: an effective tool in the fight against whiplash injuries.

Road safety engineering can play an integral part in the prevention of whiplash injuries. While improvements to vehicle design can reduce the severity of whiplash injuries when a crash occurs, improvements to road safety can prevent whiplash-inducing crashes from occurring in the first place. Whiplash injuries are most commonly associated with rear end crashes. Unfortunately, rear end crashes are also the most common type of crash at urban signalized intersections, where the majority of crashes occur in British Columbia, Canada. The Insurance Corporation of British Columbia (ICBC), through the road improvement program, has been funding road improvements in order to reduce the frequency of collisions at high crash locations in British Columbia. Several road safety engineering countermeasures specifically targeted at rear end collisions have been researched and deployed. These countermeasures include simple and affordable solutions such as signal visibility enhancements, as well as complex and expensive solutions such as intersection geometric upgrades. When appropriately used, these countermeasures have proven to be extremely cost-effective in reducing the frequency of rear end collisions. Widespread application of signal visibility enhancements is now being pursued to further decrease the risk of rear end collisions and whiplash injuries. Costs are the direct cost of the ICBC portion of the investment and benefits are only those associated with reduced insurance claims over a 2-year period.

[Reflex dystrophy following so-called whiplash injury of the cervical spine].

In bad cases of whiplash injury of the cervical spine the post-accidental course is complicated by pain, vegetative dysfunctional syndromes and by psychic and psychiatric disorders over many years. There is no satisfactory concept to understand the pathophysiology of these processes. The paper deals with the possibility of a reflex dystrophy. Sympathetic reflex dystrophy syndromes are seen principally in patients with joint, tendon or vascular lesions. In case of whiplash injury, it would concern the cervical spine itself as well as visceral organs including the central nervous system. For the CNS the lymphostatic encephalopathy is a well defined entity. Above all, a reflex dystrophy develops on the basis of a special personality structure. In case of psychic and psychiatric complaints after whiplash injury patients with a so called Sudeck-personality should not be suspected to aggravate; in contrast, especially in these patients complications by reflex dystrophy are credible. Consequences for the assessment and for rehabilitation are discussed.

Cervicocephalic kinesthetic sensibility, active range of cervical motion, and oculomotor function in patients with whiplash injury.

OBJECTIVE: To investigate cervicocephalic kinesthetic sensibility, active range of cervical motion, and oculomotor function in patients with whiplash injury. DESIGN: A 2-year review of consecutive patients admitted to the emergency unit after whiplash injury. SETTING: An otorhinolaryngology department. PATIENTS AND SUBJECTS: Twenty-seven consecutive patients with diagnosed whiplash injury (14 men and 13 women, mean age, 33.8yrs [range, 18 to 66yrs]). The controls were healthy subjects without a history of whiplash injury. MAIN OUTCOME MEASURES: Oculomotor function was tested at 2 months and at 2 years after whiplash injury. The ability to appreciate both movement and head position was studied. Active range of cervical motion was measured. Subjective intensity of neck pain and major medical symptoms were recorded. RESULTS: Active head repositioning was significantly less precise in the whiplash subjects than in the control group. Failures in oculomotor functions were observed in 62% of subjects. Significant correlations occurred between smooth pursuit tests and active cervical range of motion. Correlations also were established between the oculomotor test and the kinesthetic sensibility test. CONCLUSION: The results suggest that restricted cervical movements and changes in the quality of proprioceptive information from the cervical spine region affect voluntary eye movements. A flexion/extension injury to the neck may result in dysfunction of the proprioceptive system. Oculomotor dysfunction after neck trauma might be related to cervical afferent input disturbances.

Whiplash injuries in Finland: a prospective 1-year follow-up study.

OBJECTIVES: The aim of the study was to define how many whiplash injuries occur in Finland in traffic accidents and the degree of severity of these injuries using the whiplash-associated disorders (WAD) classification presented by the Quebec Task Force, and to define possible long-term health effects caused by whiplash injury as well as the duration of whiplash-associated sick-leaves. METHODS: This was a prospective one-year-follow-up study. Fourteen insurance companies paving compensations for traffic accidents in Finland sent the accident reports and medical certificates of all neck injuries attributable to traffic accidents to the research team. The material was collected from neck injuries that had occurred in traffic accidents during the year 1998. RESULTS: The majority of those suffering a whiplash injury were women. On the basis of the WAD classification, most whiplash injuries were mild, belonging to grades WAD I and II. At one year from the accident nearly 10% considered that their health had been impaired significantly as a result of their neck injury. Over 10% of those questioned had been on sick-leave for over a month but only 1.5% had been on sick-leave associated with the injury for more than 6 months. The most common symptom after one year was neck pain or neck pain combined with headache and symptoms in the upper extremities. No major changes related to the seasons of the year were found. CONCLUSIONS: The number of reported neck injuries in proportion to all traffic accidents involving physical injuries is small, even in proportion to rear-end collisions. In a considerable proportion of collision patients, whiplash injury does result in significant impairment which can last as long as a year after the accident. The WAD classification predicts the duration of work disability and the long-term health damage caused by the injury. Since the appearance of symptoms and the individual need for rehabilitation due to impaired functional capacity do not depend solely on the tissue damage and biomechanical forces involved in the collision, in the future it will be important to determine which factors are responsible for the differences in coping after a collision.

ECONOMIC ASPECTS OF "WHIPLASH" INJURY.

The term "whiplash," used to describe a neck injury received in an automobile accident, has no foundation in medical science to support the complaints of persons suing for damages. The term is gaining unwarranted popularity as a term describing an injury, even though there are no clinical or pathological findings to support it."Whiplash" cases today account for an estimated 30 per cent of all injuries in automobile accidents. Direct compensation for damages paid to persons injured in automobile accidents in the United States in 1961 amounted to approximately one billion, seven hundred million dollars. It has been estimated that five hundred and eighty million dollars of that amount was paid in compensation on allegation of neck injuries.

Whiplash injury of the shoulder: is it a distinct clinical entity?

The pathophysiology of shoulder pain after whiplash injury remains uncertain. Patients with shoulder pain after a whiplash injury were recruited from the accident and emergency department in a prospective study to determine the nature of indirect shoulder trauma after a whiplash injury. Twenty patients fulfilled the inclusion criteria. Magnetic resonance imaging (MRI) was obtained in 18 patients. Three MRI scans confirmed acute shoulder injuries. Two patients underwent arthroscopic subacromial decompression after failure of non- operative treatment. In conclusion, whiplash injuries can result in indirect acute shoulder trauma, possibly through an acceleration-deceleration mechanism, and may be a distinct entity.

[Whiplash injury of the cervical spine--on the role of pre-existing degenerative diseases].

Radiological investigations contribute little in differentiating the problems of patients with whiplash injuries. Nevertheless the more prolonged cases of whiplash injuries must not be attributed to preexisting degenerative disease, despite radiologically-proven medicolegal opinion. In this study, 60 patients who were seen for whiplash injuries in the Department for Trauma and Reconstructive Surgery at the University Hospital Hamburg-Eppendorf for clinical and radiological evaluation, an average of 5.7 years post injury, were divided into two groups (n = 30) depending on radiologically-proven preexisting degenerative changes of the cervical spine. On average the patients with degenerative changes were 11.2 years older than those with healthy vertebral columns and also demonstrated an increase in acute symptoms in the lower cervical spine (cervicobrachial syndrome). The chronicity of individual symptoms such as neck-pain, dizziness, nausea and psychological illness was also observed in both groups. Problems such as paresthesias as well as pain in the shoulder-arm-area appeared to increase in subsequent check-ups, irrespective of the earlier degenerative changes. Patients with typical posterior headaches recovered faster when they had radiologically normal spines. Presenting late, there was a significant accumulation of patients with pre-existing degenerative changes complaining merely of tinnitus. The earlier changes in any individual motion segment do not determine the clinical course of whiplash injuries, but merely represent an area of increased vulnerability to trauma. On the other hand, trauma has not been proven to influence the development or aggravation of degenerative changes in normal or diseased spines. We are not able to differentiate the posttraumatic course from the natural history of the degenerative process, either clinically or radiologically. Considering the involvement of sensitive neurological structures the classical objective organic diagnosis of "whiplash injury" may not be adequate in describing the complaints of patients, and should not be used to justify the rejection of the patients subjective symptoms as mere simulation for financial gains. The evaluation of the patients' X-rays using Arlen's technique sheds no further light on the issue.

Disc pathology after whiplash injury. A prospective magnetic resonance imaging and clinical investigation.

STUDY DESIGN: This study was used to evaluate the relationship between magnetic resonance imaging findings and clinical findings after whiplash injury. OBJECTIVES: To identify initial soft-tissue damage after whiplash injury, the development of disc pathology, and the relationship of disc pathology to clinical findings. SUMMARY OF BACKGROUND DATA: Although a few studies have reported pathological magnetic resonance imaging findings after whiplash injuries, there is no prospective study published to our knowledge. METHODS: Thirty-nine patients, 20 women and 19 men with a mean age of 32 years, were treated for whiplash injury. Magnetic resonance imaging and clinical examination were performed in a blinded manner at a mean of 11 days after trauma. The procedure was repeated at a 2-year follow-up visit. Two patients could not be examined with the second magnetic resonance imaging because of claustrophobia and pregnancy, respectively. RESULTS: The authors found 13 patients (33%) with disc herniations with medullary (six cases) or dura (seven cases) impingement over the 2-year follow-up period. At the follow-up examination all patients with medullary impingement had persistent or increased symptoms, and three of 27 patients (11%) with no or slight changes on magnetic resonance imaging had persistent symptoms. No ligament injuries were diagnosed. CONCLUSION: Although disc pathology seems to be one contributing factor in the development of chronic symptoms after whiplash injury, it may be unnecessary to examine these patients in the acute phase with magnetic resonance imaging; correlating initial symptoms and signs to magnetic resonance imaging findings is difficult because of the relatively high proportion of false-positive results. Magnetic resonance imaging is indicated later in the course of treatment in patients with persistent arm pain, neurologic deficits or clinical signs of nerve root compression to diagnose disc herniations requiring surgery.

Sleep disturbances after whiplash injury: objective and subjective findings.

OBJECTIVE: A controlled objective and subjective evaluation of sleep in a consecutive series of persons who had had a whiplash injury, shortly following the injury and 3 to 5 months later. METHODS: In whiplash-injured subjects and healthy controls, sleep characteristics were monitored objectively throughout the night by means of an actigraph. The following morning, participants in both groups filled out a prestructured "sleep log" that conveyed their subjective impressions as to how they had slept. The correlation between objectively measured sleep characteristics and the symptoms and physical findings, respectively, resulting from whiplash injury were also examined. RESULTS: Actigraphic monitoring did not reveal a significant group difference between whiplash-injured subjects and controls with respect to any of the sleep characteristics recorded. In self-maintained "sleep logs," however, the whiplash-injured subjects reported a significantly prolonged sleep latency and significantly impaired sleep quality compared with controls (P<.001 and P<.04, respectively). In whiplash-injured subjects, the number of arousals was positively correlated with the number of symptoms and with the number of physical signs of whiplash injury (P<.01 and P<.001, respectively). Sleep efficiency was inversely correlated with the number of injury-related findings on physical examination (P<.009). CONCLUSION: Sleep, as monitored by actigraph in whiplash-injured subjects, was not adversely affected by whiplash injury. The subjective impressions of the subjects, as recorded in "sleep logs," suggest the opposite conclusion. A significant correlation exists between certain symptoms and signs of whiplash injury and abnormalities in given sleep characteristics as detected by actigraph.

Neck muscle fatigue and postural control in patients with whiplash injury.

OBJECTIVES: To examine if patients with whiplash injury show identifiable increases in neck muscle fatigability and associated increase in postural body sway after contractions of dorsal neck muscles, and if physiotherapy treatment reduces these effects. METHODS: Sway was measured during stance in 13 patients before and after 5 min of isometric dorsal neck muscle contractions and after recovery, pre- and post-physiotherapy, using a force platform. Amplitude and median frequency of neck muscle EMG were calculated during the contracting period. After each stance trial, patients gave a subjective score of sway. RESULTS: Pre-treatment, seven patients showed EMG signs of fatigue (increases in amplitude, decreases in median frequency) and increases in sway (eyes closed) after contractions. The other patients showed neither fatigue nor increased sway. Post-treatment, no signs of fatigue or imbalance were recorded in all patients, for the same levels of muscle contraction. CONCLUSIONS: As in normal human subjects, increases in sway are associated with signs of neck muscle fatigue in some whiplash injury patients. Physiotherapy decreases the susceptibility to fatigue of neck muscles and is an effective choice of treatment of subjective instability and sway. SIGNIFICANCE: This study demonstrates a pathophysiological link between neck muscle fatigue and impaired postural control, and also that physiotherapy can relieve symptoms and signs of impaired neck muscle function by reducing muscle fatigability.
