Objectives : Ohyaksungi-san(Wuyaoshunqi-san) has been used for many years as a treatment for sciatica in oriental medicine. And electrical acupuncture also has been used as a treatment for sciatica in recent study. By the way, it is hard to find the study that apply two treatments in the same time. This study was designed to evaluate the effects of Ohyaksungi-san(Wuyaoshunqi-san) and electrical acupuncture on nerve regeneration after crush injury in rat sciatic nerve in the same time. Methods : This study was designed with 4 subgroups to evaluate the effects of Ohyaksungi-san(Wuyaoshunqi-san) and electrical acupuncture on nerve regeneration. As control groups, group I has not been treated during 3 weeks after crush injury in rat sciatic nerve. Group II has been treated Ohyaksungi-san(Wuyaoshunqi-san), Group III has been treated electrical acupuncture, and Group IV has been treated both during 3 weeks. This study has been estimated sciatic function index and change of GAP-43 immunoreactivity about sciatic nerve regeneration. Results : 1. The test for nerve regeneration had significantly good result of sciatic function index in the experimental groups as compared with control groups(p<.05). Especially, Group IV has the greatest result of sciatic function index. 2. GAP-43, the marker of nerve regeneration, more increased in the experimental groups as compared with control groups. Especially, Group IV has the greatest result of GAP-43. Conclusions : Ohyaksungi-san(Wuyaoshunqi-san) and electrical acupuncture have good effects on nerve regeneration after crush injury in rat sciatic nerve.

Time-loss injuries are still a major occurrence in Canada, injuring thousands of Canadian workers each year. With obesity rates on the rise across the country, as well as around the world, it is important that the possible effects of obesity in the workplace be fully understood, especially those effects linked to lost-time injuries. The aim of this paper was to evaluate predictors of workplace lost-time injuries and how they may be related to obesity or high body mass index by examining factors associated with lost-time injuries in the health care sector, a well-studied industry with the highest number of reported time loss injuries in Canada. A literature review focusing on lost-time injuries in Registered Nurses (RNs) was conducted using the keywords and terms: lost time injury, workers' compensation, occupational injury, workplace injury, injury, injuries, work, workplace, occupational, nurse, registered nurse, RN, health care, predictors, risk factors, risk, risks, cause, causes, obese, obesity, and body mass index. Data on predictors or factors associated with lost-time injuries in RNs were gathered and organized using Loisel's Work Disability Prevention Management Model and extrapolated upon using existing literature surrounding obesity in the Canadian workplace.

As S. Korea is becoming an "aged society", workers in the country would be exposed to higher risk of workplace injuries due to their reducing work abilities as they are getting old. To identify the relationship between the work ability and the incident rate of workplace injuries, the work ability index (WAI) scores were surveyed from 409 workers occupied in different manufacturing industries reside on north GyoengBuk area. The workplace injury statistics in the year of 2010 for the corresponding industries were analyzed and summarized with the WAI scores by age groups, years of service, and sizes of business. The results showed the WAI scores of the workers occupied in the higher risk of workplace injury was lower than that of the workers of the lower risk. It means the lower the WAI score, the higher the chance of being injured during the task. It is concluded that appropriate correlation exists between the WAI scores of workers and the incident rate of workplace injury. It is recommended to administrate individual work abilities of aged workers in order to keep low rate of workplace injuries in upcoming aged and highly aged society.

This study was conducted to assess the effects of the gait training method in incomplete spinal cord injured persons using an auto-walking machine. Persons with incomplete spinal cord injury level C or D on the American Spinal Injury Association impairment scale participated for eight weeks in an auto-walking training program. The gait training program was carried out for 15 minutes, three times per day for 8 weeks with an auto-walking machine. The foot rests of the auto-walking machine can be moved forward, downward, backward and upward to make the gait pattern with fixed on crank. The patient's body weight is supported by a harness during waking training. We evaluated the gait speed, physiologic cost index, motor score of lower extremities and the WISCI (walking index for spinal cord injury) level before the training and after the forth and eighth week of walking training. 1. The mean gait speed was significantly increased from .22 m/s at pre-training to .28 m/s after 4 weeks of training and .31 m/s after 8 weeks of training (p=.004). 2. The mean physiologic cost index was decreased from 4.6 beats/min at pre-training to 3.0 beats/min after 4 weeks and 2.0 beats/min after 8 weeks of training, but it was not statistically significant (p=.140). 3. The mean motor score of lower extrernities was significantly increased from 29.8 to 35.8 after 8 weeks of training (p=.043). 4. The mean WISCI level was significantly increased from level 10 to level 19 after 8 weeks of training (p=.007). The results of this study suggest that the gait training program using the auto-walking machine increased the gait speed, muscle strength and galt pattern (WISCI level) in persons with incomplete spinal cord injury. A large, controlled study of this technique is warranted.

Objectives : The purpose of this study is to investigate the cervical spine curvature after whiplash injury by traffic accident. Methods : The cervical lateral radiographs of 102 outpatients who visited emergency room in Kyung-Hee university hospital at Gangdong after whiplash injury by road traffic accident were reviewed to measure the cervical spine angle using C1-7, C2-7 Cobb method, Sagittal tangent method, Jochumsen method and the Ishihara index by two oriental medical doctors. For statistics, we used SPSS version 17.0 for windows. Results : Means of cervical angle are $37.63{\pm}11.34^{\circ}$, $12.92{\pm}9.13^{\circ}$, $16.19{\pm}10.62^{\circ}$, $1.78{\pm}3.37$ and $8.51{\pm}9.78$ by C1-C7 Cobb Method, C2-C7 Cobb Method, Sagittal tangent method, Jochumsen method and Ishihara index, respectively. Hypolordosis is most numeral in patients by C1-C7 Cobb Method(n=40; 39.22%), Sagittal tangent method(n=68; 66.67%). And Straight is the most by Jochumsen method(n=54; 52.94%), but Normal is the most by Ishihara index(n=53; 51.96%). And Female has smaller curvature in cervical spine than male significantly by C2-C7 Cobb method and Sagittal tangent method(P<0.05). Conclusions : Whiplash injury tends to make hypolordosis or straight. And female has more vulnerable curvature than male in whiplash injury.

The main purposes of this study were to find the correlation between walking ability assessment tools using the Modified Barthel Index (MBI), Functional Independence Measure (FIM), Spinal Cord Injury Measurement II (SCIM II), Walking Index for Spinal Cord Injury (WISCI), walking velocity, and walking endurance. The study population consisted of 56 patients with spinal cord injury referred to the department of Rehabilitative Medicine in the National Rehabilitation Hospital. All subjects were ambulatory with or without an assistive device. All participants were assessed by MBI, FIM, SCIM II, WISCI, walking velocity, and walking endurance. The data were analyzed using Pearson correlation analysis and X2. There was significant correlation between the MBI, FIM, SCIM II, WISCI, walking velocity, and walking endurance (p<.01). In particular, WISCI has a significant correlation with SCIM II(p<.001). Therefore the WISCI scale is an appropriate assessment tool to predict the gait ability of patients with spinal cord injury. Further study about MBI, FIM, SCIM II, WISCI, walking velocity, and walking endurance is needed using a longitudinal study design.

Peripheral nerve injuries are a commonly encountered clinical problem and often result in chronic pain and severe functional deficits. At the Dept. of Oriental Rehab. Medicine, we have used for pain control a herbal bath containing the following herbs: Harpagophytum radix, Atractylodes japonica and Corydalis tuber. In the present study, we investigated the effects of this herbal bath on the recovery rate of the locomotor function and the expression of c-Fos in the ventrolateral periaqueductal gray (vIPAG) region of the brain following sciatic crushed nerve injury in rats. In the present study, characteristic gait change with decreasing of the sciatic function index (SFI) was observed and c-Fos expression in the vIPAG was suppressed following sciatic crushed nerve injury in rats. Immersion into herbal bath enhanced SFI value and restored c-Fos expression in the vIPAG to the control value. These results suggest the herbal bath might activate neurons in the vIPAG, and could facilitate functional recovery from peripheral nerve injury.

Objectives : Peripheral nerve injuries are commonly encountered clinical problems and often result in severe functional deficits. Sukjiyanggeun-Tang(shudiyangjin-tang), in oriental medicine, has been used to treat various musculoskeletal disorders. Methods : In the present study, the effects of aqueous extract of Sukjiyanggeun-Tang(shudiyangjin-tang) on functional recovery, severity of pain, and expressions of neurofilament, cycloxygenease-2(COX-2), inducible nitric oxide synthase(iNOS), and tumor necrosis factor-${\alpha}$(TNF-${\alpha}$) following sciatic crushed nerve injury in rats were investigated. For this study, walking tract analysis, plantar test, western blot analysis for COX-2 iNOS, and TNF-${\alpha}$, and Immunofluorescence test for neurofilament were performed. Results : In the present results, sciatic functional index(SFI) in walking tract analysis was significantly decreased following sciatic crushed nerve injury, and pain severity in plantar test was significantly increased. COX-2, iNOS and TNF-${\alpha}$ expressions were increased whereas neurofilament expression was decreased by sciatic crushed nerve injury, In contrast, treatment with Sukjiyanggeun-Tang(shudiyangjin-tang) improved SFI in walking tract analysis and suppressed the pain severity in sciatic crushed nerve injury. Sukjiyanggeun-Tang(shudiyangjin-tang) treatment also suppressed COX-2, iNOS, and TNF-${\alpha}$ expressions and enhanced the neurofilament expression in sciatic crushed nerve injury. Conclusions : In the present study, we have shown that Sukjiyanggeun-Tang(shudiyangjin-tang) is the effective therapeutic modality to ameliorate the symptoms of sciatic crushed nerve injury.
