Acute treatment of whiplash neck sprain injuries. A randomized trial of treatment during the first 14 days after a car accident.

STUDY DESIGN: A single-blinded, randomized treatment study with a follow-up period of 6 months. OBJECTIVE: To study the long-term consequences of whiplash neck sprain injuries in patients treated with two different regimes during the first 14 days after the car accident. Patients in the first group were encouraged to act as usual, i.e., continue to engage in their normal, pre-injury activities; that group was compared with another group of patients who were given time off from work and who were immobilized using a soft neck collar. The end point of the comparison was the evaluation of subjective symptoms 6 months after the accident. SUMMARY OF BACKGROUND DATA: Few randomized treatment studies have been performed to evaluate the clinical outcome for patients with neck sprain. METHOD: Patients who participated in the study were recruited from the Emergency Clinic at the University Hospital in Trondheim, Norway. The study group included 201 patients (47% of the study group) with neck sprain that resulted from a car accident. Neck and shoulder movements and subjective symptoms, which were assessed using several different measurements, were assessed during the follow-up period. RESULTS: There was a significant reduction of symptoms from the time of intake to 24 weeks after the treatment period in both groups. There was a significantly better outcome for the act-as-usual group in terms of subjective symptoms, including pain localization, pain during daily activities, neck stiffness, memory, and concentration, and in terms of visual analog scale measurements of neck pain and headache. CONCLUSIONS: The outcome was better for patients who were encouraged to continue engaging in their normal, pre-injury activities as usual than for patients who took sick leave from work and who were immobilized during the first 14 days after the neck sprain injury.

MRI of cerebrum and cervical columna within two days after whiplash neck sprain injury.

The present study was undertaken to evaluate if MRI within 2 days of a motor vehicle accident could reveal pathology of importance for understanding long-term disability after whiplash neck-sprain injuries. As part of a prospective study cervical and cerebral MRI was performed on 40 neck sprain patients with whiplash injury after car accidents. The imaging was done within 2 days of the injury to make sure that any neck muscle bleeding, oedema or other soft tissue injuries could be detected. The MRI findings from the patients were both correlated to reported symptoms 6 months after the accident and compared to a control group of 20 volunteers. The MRI of both brain and neck revealed no significant differences between the patients and the control group. When the patients were grouped according to the main MRI findings at intake and compared according to the development of subjective symptoms reported by the patients, the only significant difference was more headaches at 6 months in the groups with disk pathology or spondylosis when compared to the group with no pathology. In conclusion, MRI within 2 days of the whiplash neck-sprain injury could not detect pathology connected to the injury nor predict symptom development and outcome.

Personality profile among symptomatic and recovered patients with neck sprain injury, measured by MCMI-I acutely and 6 months after car accidents.

The relationships between personality and psychiatric symptoms and long-lasting physical symptoms were assessed in 88 neck sprain patients injured in car accidents. The Millon Clinical Multiaxial Inventory (MCMI-I) was completed at time of occurrence (intake) and 6 months after the injury. The neck sprain patients were divided into three subgroups according to symptoms 6 months after the accident. In addition, the total neck sprain group was compared with three other subject groups. The results indicated that the three neck sprain subgroups did not differ on the MCMI-I neither at intake nor 6 months later. The total neck sprain patients group was significantly different from patients with major depression on all scales of the MCMI-I, but not significantly different compared to patients with localized musculoskeletal pain. Compared to a group of health personnel, there were only a few significant differences. The study does not support the view that premorbid personality traits can predict outcome for neck sprain patients.

National health insurance consumption and chronic symptoms following mild neck sprain injuries in car collisions.

OBJECTIVE: To map the extent of sick leave and number of claims made for health insurance among persons who had suffered neck sprain (whiplash) injuries in traffic accidents, and to map subjective feeling of health and quality of life among patients several years after the injury. DESIGN: A retrospective study of neck sprain injuries after car accidents and a comparison to the patients' use of sick leave caused by neck pain prior to the accident. SETTING: The Emergency Clinic at The University Hospital in Trondheim, Norway. SUBJECTS: 426 patients with neck sprain injuries after car accidents during 1985-1990. MAIN OUTCOME MEASURES: Information from Trondheim Social Security office about sick leave, and results from 345 patients who answered a questionnaire with respect to quality of life measures. RESULTS: 27% had been reported sick during the period after the car accident, and 5% had claimed health insurance, 58% reported sustained symptoms linked to the accident. CONCLUSIONS: Many reported sustained symptoms after neck sprain injuries, 16% of them reported being in a bad state of health.

MR imaging and radiography of patients with cervical hyperextension-flexion injuries after car accidents.

Fifty-two patients underwent MR imaging and conventional radiography of the neck within 4 days after a hyperextension-flexion injury. The patients also had follow-up investigations during the first 2 years. The images did not reveal any serious lesions in any of them. Based on the main MR and radiographical findings the patients were divided into 4 groups; no findings, posture abnormalities, spondylosis and disc pathology (from MR images) or reduced intervertebral space (from the radiographs). The outcomes of the different groups were compared with reference to neck stiffness, neck pain and headache during a 2-year follow-up period. The patient groups did not correspond completely when diagnosed from MR imaging and radiography. However, patients with pre-existing spondylosis had more symptoms when examined by both modalities. Based on the radiographs, the group with posture abnormalities had significant fewer symptoms than the other groups.

The effects of brain temperature on temporary global ischaemia in rat brain. A 31-phosphorous NMR spectroscopy study.

31-Phosphorus magnetic resonance spectroscopy was used in a rat model of 10 min severe incomplete forebrain ischaemia (2-vessel occlusion with hypotension) to assess the effect of mild brain hypo- and hyperthermia (+/- 2 degrees C) on intracellular pH and high energy phosphates. In three experimental groups intracerebral temperature was maintained at levels of 34, 36 and 38 degrees C during ischaemia and early reperfusion. The steady level of intracellular pH during ischaemia was 6.63, 6.58 and 6.53 in the 34, 36, and 38 degrees C groups, respectively. The rate of initial recovery of intracellular pH in reperfusion was 0.046 +/- 0.012 pH units per min (+/- s.d.) in the 36 degrees C group compared to 0.056 +/- 0.010 (+/- s.d., P less than 0.05) in the 34 degrees C group and 0.032 +/- 0.009 (+/- s.d., P less than 0.01) in the 38 degrees C group. The recovery in early reperfusion of phosphocreatine and ATP was slower in the 38 degrees C group compared to the other groups. The findings were consistent with recent studies, suggesting that even mild hypothermia may afford protection to the ischaemic brain, and furthermore indicate that mild hyperthermia as fever or even subfebricity may be deleterious for the outcome in stroke patients.

[Symptoms in patients with neck injury after a car crash. A retrospective study]. / Symptomer hos pasienter med nakkeskade etter bilkollisjon. En retrospektiv undersøkelse.

139 persons who contacted The Regional Hospital, Trondheim, between 1 January and 1 September for whiplash injury caused by a car crash from behind were asked whether they still had problems six months or more after the accident. 51% reported having symptoms and 12% reported serious problems. Five persons were still out of work because of the neck injury. 63% of the questioned persons were female and the percentage of women increased with increasing symptoms. There was no correlation between age and problems. There were more persons without symptoms among office employees (70%), managers/university educated persons (53%) and students/pupils (50%) than among unskilled workers/professional drivers (35%) and housewives/retired persons/pensioners/unemployed (35%).
