Clay-shoveler's fractures are rare stress-type avulsion fractures of the spinous processes especially in sports. There have been two case reports that discussed clay-shoveler's fractures in golf. A 36-year-old beginner golfer presented with a pain in the back after practicing golf swing. No fractures were detected using cervical radiography; however, computed tomography (CT) and magnetic resonance imaging (MRI) revealed T2~T3 spinous process fractures. The patient was treated conservatively and his pain subsided. The mechanism of injury is speculated to that of clay-shoveler's fractures. Therefore, if a golfer suffers persistent pain in the cervicothoracic region, clay-shoveler's fracture is one possibility to consider.

Objectives : The purpose of this study was to determine whether electroacupuncture(EA) is effective in reducing pain on the severe ankle sprain classified as grade 3 in rats. Methods : The severe(grade 3) ankle sprain model was induced surgically by ankle ligament injury(the anterior talofibular, the calcaneofibular and the posterior talofibular) in the Sprague-Dawley rats(180~250 g). The effects of EA on weight bearing forces(WBR) of the affected foot were examined in a rat model of ankle sprain. EA was applied to either SI6, ST37, GB34, GB39 or GB42 acupoints by trains of electrical pulses(2 Hz, 1 ms pulse width, 2 mA intensity) for 15 min. Results : Cutting of the lateral ankle ligament complex produced the severe ankle sprain symptoms as grade 3. EA of the contralateral SI6 resulted in more analgesic effect than one of ipsilateral SI6 even though there was significant effect. EA of the ipsilateral GB34 and GB39 produced potent analgesic effects on the surgical ankle sprained pain behaviors. However, there were no significant analgesic effects in the contralateral GB34 and GB39 EA groups. In addition, both side of ST37 and GB42 did not result in analgesic effect on the surgical ankle sprained rat. Conclusions : The data suggest that EA induced analgesia shows point specificity on the severe ankle sprained pain model classified as grade 3.

The purpose of this study was to the kinetic variables effects from the use of arch support inserts on low-arched people. We selected 10 people for the research and separated them into 2 groups, 5 people for the normal arched group and 5 people for the low arched group. Each group wear shoes which have a 3 step convertible arch support (level 0, level 2, level 5) and we measured their foot pressure and 3D motion analysis data. As a result, we found that the mean pressure at the heel of the low arched group was decreased when using the arch supports. The arch support induced the correct grounding area for the foot and dispersion of foot pressure. 3D motion analysis found that as the height of the arch support was increased, the movement of the Y-axis(inversion-eversion) was increased to relieve the shock to the heel. The arch support insert limited the range of motion(ROM) of the Z-axis(abduction-adduction) of the low arched person's ankle joint and prevented ankle injury caused by the excessive eversion when walking. Low arched people are seen to be easily tired due to the ineffective shock absorption of the knees and abnormal walking motion. In order to improve the problems, a 3 step convertible arch support(level 5) insert would improve the low-arched people's walking ability. In other words, the low arched people should be expected to walk as well as normal arched people when they wear shoes with the arch support insert.

본 연구는 대학생을 대상으로 지연성근육통 유발 후 수동적 스트레칭의 효과를 확인하고 부상 시 효과적인 통증완화 및 예방을 위한 재활 운동프로그램을 제안하고자 한다. 연구대상자는 20대 남자 대학생을 대상으로 수동적 스트레칭그룹과 통제그룹으로 구분하였다. 수동적 스트레칭 그룹은 지연성근육통 유발 후 수동적 스트레칭을 실시하였으며 통제그룹은 지연성근육통 유발 후 어떠한 처치도 실시하지 않았다. 지연성근육통 유발 방법은 벤치 스텝 운동을 통하여 유발하였으며, 스텝박스의 높이는 50cm이며, 착지 시 왼쪽 하지 쪽으로 착지하도록 하였다. 측정변인은 혈중피로물질과 주관적 통증척도를 알아보았으며 자료처리는 수동적 스트레칭 그룹과 통제그룹의 비교를 위하여 2-way RGRM ANOVA를 실시하였다. 결론적으로 지연성근육통 유발 후 수동적 스트레칭이 혈중피로물질(CRP, LDH)과 주관적 통증척도(VAS)에 긍정적 효과가 있는 것으로 나타났다.

Objectives : Electroacupuncture(EA) has been used effectively in producing analgesia on ankle sprain pain of humans and animals. Currently to examine the underlying mechanisms of the EA-induced analgesia, the effects of EA on weight-bearing forces(WBR) were examined at ankle sprain classified as grade 3 in rats. Methods : The severe ankle sprain classified as grade 3 was induced surgically by ankle ligament injury in the Sprague-Dawley rats. WBR of the affected foot were examined to evaluate effects and mechanism of EA(2 Hz, 1 ms pulse width, 2 mA intensity, for 15 min) which was applied to either SI6, GB34, or GB39 acupoints. The rats were pretreated with naltrexone(10 mg/kg, i.p.) as an opioid receptor antagonist or phentolamine(5 mg/kg, i.p) as an ${\alpha}$-adrenoceptor antagonist at 30 min before EA. Results : The daily repeat EA at either SI6, GB34, or GB39 showed significant analgesic effects on the severe ankle sprain. Particularly, daily EA at GB34 showed more potent analgesic effect than the others. In addition, the naltrexone pretreatment completely blocked the analgesic effect of EA at GB34, indicating the involvement of the endogenous opioid system in mediating the effect of EA at GB34. However, the phentolamine pretreament blocked analgesic effects of EA at either SI6 or GB39, indicating the involvement of ${\alpha}$-adrenoceptors in mediating the effect of EA at either SI6 or GB39. Conclusions : These data suggest that EA-induced analgesia on ankle sprain pain is mediated through either endogenous opioids or ${\alpha}$-adrenoceptors dependant on acupoint specific pattern.
