  • 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.

  • 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.

  • 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.

  • Objective : This study aims to visualize the subjective symptoms before and after the treatment of whiplash injury using infrared (IR) thermography. Methods : IR thermography was performed for 42 patients who were diagnosed with whiplash injury. There were 19 male and 23 female patients. The mean age was 43.12 years. Thermal differences (${\Delta}T$) in the neck and shoulder and changes in the thermal differences (${\Delta}dT$) before and after treatment were analyzed. Pain after injury was evaluated using visual analogue scale (VAS) before and after treatment (${\Delta}VAS$). The correlations between ${\Delta}dT$ and ${\Delta}VAS$ results before and after the treatment were examined. We used Digital Infrared Thermal Imaging equipment of Dorex company for IR thermography. Results : The skin temperature of the neck and shoulder immediately after injury showed $1-2^{\circ}C$ hyperthermia than normal. After two weeks, the skin temperature was normal range. ${\Delta}T$ after immediately injuy was higher than normal value, but it was gradually near the normal value after two weeks. ${\Delta}dT$ before and after treatment were statistically significant (p<0.05). VAS of the neck and shoulder significantly reduced after 2 week (p=0.001). Also, there was significant correlation between ${\Delta}dT$ and reduced ${\Delta}VAS$ (the neck; r=0.412, p<0.007) (the shoulder; r=0.648, p<0.000). Conclusion : The skin temperature of sites with whiplash injury is immediately hyperthermia and gradually decreased after two weeks, finally it got close to normal temperature. These were highly correlated with reduced VAS. IR thermography can be a reliable tool to visualize the symptoms of whiplash injury and the effectiveness of treatment in clinical settings.

  • The purpose of this study is to provide the case of influence of myofacial release(MFR) and cryotherapy in acute whiplash injury. The subjects were consisted of 3 adults(2 males, 1 female) who had been diagnosed with whiplash injury. The performance period was 1 weeks, 6 times and 1 time is 40min(MFR: 20min, cryotherapy: 20min). We measured neck pain(Visual analogue scale, VAS) and cervical alignment(cervical curvature & line of gravity). All measurements of each subject were measured at pre-treatment and post-treatment. The results are listed below. The neck pain(VAS) index decreased from 7.54cm to 4.11cm. The cervical curvature increased from $23.62^{\circ}$ to $29.76^{\circ}$. The line of gravity decreased from 8.03mm to 3.66mm. Based on the results, it can be suggested that both MFR and cryotherapy can be used to neck pain and alignment in acute whiplash injury.

  • Objectives The purpose of this study is to provide more whiplash injury-specific measurement tools for Korean patients by measuring the validity and reliability of Korean version of Whiplash Disability Questionnaire (WDQ). Methods Bilingual clinicians translated the original WDQ into Korean. After consensus conference between researchers, it was back-translated into English. The pre-final version was completed and administered to 71 hospitalized patients diagnosed with whiplash injury. Validity was evaluated by concurrent validity. Reliability was assessed using Cronbach's ${\alpha}$ and intraclass correlation coefficient. Results The Korean WDQ showed good reliability with high internal consistency and intra-class correlation coefficient (Cronbach's ${\alpha}=0.96$, intraclass correlation coefficient [ICC]=0.82). Concurrent validity demonstrated positive correlations between Neck Disability Index, 36-Item Short Form Health Survey and WDQ. Conclusions The Korean version of WDQ is a valid and reliable tool for use as a measurement of whiplash injury in Korean patients, and it will be a very useful evaluation tool for both clinicians and researchers.
