In this study, the effects of sitting position of the driver on the whiplash neck injury have been analyzed experimentally by using hybrid III series 50 percentile male crash test dummy. A testing platform consisting of vehicle ground, driver foot rest, driver seat and a 3-point seatbelt has been prepared. This testing platform and the instrumented crash test dummy are prepared for tests according to the Euro NCAP whiplash testing protocol. The prepared test set-up has been exposed to 3 different acceleration-time loading curves defined in the Euro NCAP whiplash testing protocol by performing sled tests. 9 different sled tests have been performed with the combinations of 3 different seating positions of the crash test dummy and 3 different acceleration-time loading curves. The sensor data obtained from the crash test dummy and high-speed videos taken are analyzed according to the injury assessments criteria defined in the Euro NCAP whiplash testing protocol and the criticality of the whiplash injury is defined. It is seen that the backset distance of the driver head with the headrest and the height difference of the top of the head of the driver with the headrest have a great importance on whiplash injuries.

Objectives : This study is to applied effectively to the acupuncture treatment for disorders following whiplash injuries. Methods : This study suggests five various ways and principtes of treating disorders following whiplash injuries by means of acupuncture. First principle is that acupuncture treatment is carried out on acupoint far from cervical spine at acute stage, on the other hand, Extraordinary Vessel and other acupuncture treatment such as five element acupuncture treatment is applied at chronic stage in order to control balance disoders due to cervical pathology. Second is acupuncture treatment will be performed in group of three part of Meridian System-Yangmyung, Taeyang, Soyang-according to cervical kinetic, its characteristic and location of pain. Third is acupuncture treatment could be performed on basis of theory of Eohyel-disorders and disturbance of blood circulation. Fourth is to decrease tension of SCM muscle, because disorders following whiplash injuries has much association to injury of CM muscle and is simillar to tension syndroms of SCM muscle. fifth is taping therapy could control and decrease disorders following whiplash injuries based on spiral balance taping theory. Conclusions : These results suggest that acupuncture treatment for disorders following whiplash injuries will significally decrease pain and control syndrom caused by cervical disorder.

Whiplash is the most frequent injury among occupants in low speed rear-end car collision. The aim of this paper is to analyze thecorrelation between influence parameters of head restraints and whiplash injury criteria.In this paper, DFSS (Design for Six Sigma) method is used for optimum design of head restrains. Four control factors of head restraints have selected by function matrix method. The effects of the control factors have been experimentally evaluated by using a sled pulse from 16km/h relative velocity which is suggested by KNCAP (Korean New Car Assessment Program). In order to reduce the noise factors of dynamic tests, whiplash tests were repeated twice. By using DFSS, the correlation between control factors and injury criteria has been comprehended.

"Whiplash"-type injuries are commonly encountered and often cause neck pain, neck stiffness, and headaches. However, these injuries can have rare and poorly recognized complications, such as the development of a prevertebral hematoma leading to acute respiratory failure in the emergency department, followed by severe, life-threatening dysphagia and recurrent aspirations. In the patient described herein, a whiplash injury was accompanied by vocal cord paralysis and dysphonia (vagus nerve), dysgeusia (glossopharyngeal nerve, vagus nerve), and upper esophageal spasm (cricopharyngeal muscle, vagus nerve). It is unlikely that this was a complication of cervical fusion surgery. Instead, a combined stretch-induced lower cranial nerve injury, possibly on the exit of these nerves through the jugular foramen, seems to be a likely, but underappreciated mechanism occurring in rare instances of whiplash injuries.

Objective: We intended to show the relation between whiplash injury and deviation of upper cervical through analysing patients having deviation of upper cervical injuried by whiplash. Methods: We chose 40 patients who have been admitted for whiplash injury syndrome in vertebral-joint center of Conmaul oriental medical hospital during 2001.10.1-2003.10.15. We examined cervical simple X-ray of them according to the traffic accident patterns and the position in the veicle. Results: The 97% of the cases showed AS deviation and the 95% of them complained neck pain. The first cases collided from the back on the driving seat showed AS deviation. The second cases collided from the front on the back seat showed AS deviation of left lateral misalignment of atlas. The third cases collided from the front on the assistant seat showed AS deviation of right lateral misalignment of atlas.

The whiplash Injuries due to rear collision occur frequently. As result, in many countries, seat performance is being assessed and developed to improve head whiplash injury in rear collision of passenger car. This study compares whiplash assessment methods in each country. Using the DFSS(Design for Six Sigma) method, the correlation between influence parameters of head restraints and whiplash injury criteria is analyzed. Four control factors are used in this study. And total 11 whiplash injury criteria from NCAP(New Car Assessment Program) of Korea, Europe, China and IIHS(Insurance Institute for Highway Safety) of USA are used for output response. By the experimental design, L9 orthogonal coordinate system is configured and is tested by sled test equipment, twice. By using average assay value and ANOVA, the correlation between control factors and injury criteria has been comprehended. Optimization design of head restraint according the regional seat safety assessment was derived through the correlation.

The clinical features and therapeutic results of alopecia areata are variable and unpredictable. For example, genetic, psychic, immunologic factors are regarded as the reason of alopecia areata. For the relationship between alopecia and whiplash injury, Dr. Guun explained that whiplash injury by the traffic accident produces cervical muscle spasm, and it makes autonomic nerve change. The tropical changes accompanied with ischemic change of scalp vessels made by this mechanism cause alopecia areata. And Yesudian reported the case of scalp alopecia as the result of ischemic change following traffic accident. We have experienced a 25-year-old woman with Alopecia areata following whiplash injury by traffic accident, and who had no risk factor of it. The patient was treated by acupuncture and physical treatment. Her hair loss, cervical angle and pain were improved through acupuncture treatment. This case of alopecia areata following whiplash injury is uncommon, so we report the mechanism of it, but should collect more cases and observations.
