Purpose: This study aimed to describe the pattern of injuries and illnesses among Korean athletes during the Almaty Winter Universiade 2017. Methods: All medical staffs of Korean team recorded the daily occurrence of injuries and illnesses sustained during the Almaty Winter Universiade Games by using a standardized online form via kociss.com. The design of this study was a prospective study. Results: In total, 98 athletes (68 men and 30 women) in 11 sports events from Korean Sport Olympic Committee participated in this study. Korean medical staffs reported 40 injuries (40.8%) and 26 illnesses (26.5%), equaling incidences of 6.3 injuries and 4.1 illnesses per 100 athletes. Men suffered more injury and illness than women (44.1% vs. 33.3%). The rate of Injury and illness in training was higher than the competition (13.3 vs. 2.0 athlete exposures). The risk of an athlete being injured was the highest in freestyle skiing, followed by snowboard and speed skating. Overall, the main common type and location of injury was the joint or ligaments sprain (13.3%) and knee (7.1%). The rate of main illness was 17.3% of the respiratory system with the main symptom of pain and the main cause of environment (22.4%). Conclusion: Injuries and illnesses occurred 40.8% and 26.5% during this winter game, and were higher during training than a competition. Based on the epidemiologic data of this study, it could provide the source for the injury prevention and improving the performance of the athlete and further develop scientific injury and illness surveillance systems.

정희성(Jeong, Hee-Seong),맹준호(Maeng, Joon-Ho) 한국노인복지학회 2020 노인복지연구 Vol.75 No.3

본 연구는 독거노인의 자기방임을 예방하기 위한 기초연구로, 위기적 생활사건 스트레스가 자기방임에 미치는 영향과 자아통제감의 매개효과를 실증적으로 검증하였다. 대전광역시에서 노인돌봄기본서비스를 이용하는 65세 이상 독거노인을 대상으로 면접조사를 실시하였고, 370명에 대한 자료를 분석에 활용하였다. 구조방정식모델을 통한 분석 결과, 본 연구에서 제시한 모형의 적합도가 CFI=.965, RMSEA=.051로 양호한 적합성을 나타냈다. 이를 통해 자아통제감이 낮을수록(β=-.372, p<.001), 위기적 생활사건 스트레스가 높을수록(β=.188, p<.05), 자기방임 정도가 높게 나타났다. 또한 매개효과 검증에서 노인의 자아통제감이 위기적 생활사건 스트레스와 자기방임을 매개하는 것으로 확인되었다. 연구 결과를 바탕으로 독거노인의 자기방임 현상을 해소하기 위해 자기방임에 대한 인식개선, 실천 전문가를 대상으로 한 교육, 예방적 시스템의 구축 및 보완에 대한 실천적 방안을 제시하였다. The study is to prevent self-neglect of the elderly living alone. For this reason, it verified empirically the influence of stress of critical life events on self-neglect and the mediating effects of a sense of mastery. For this, survey were conducted on the elderly living alone who are over 65 years old and using basic elderly care services in Daejon City and data from 370 people used for analysis. analysis conducted through structural equations model showed that the goodness of fit of the model presented in this study was favorable with CFI=.965 and RMSEA=.051. So, one hwo has a low sense of mastery (β=-.372, p<.001) or a higher stress of critical life events (β=.188, p<.05) caused much higher levels of self-neglect. In addition, the sense of mastery of the elderly mediated between stress of critical life events and self-neglect. Based on the results of this study, practical alternatives were presented for awareness improvements on self-neglect, education for practical experts, and the establishment and supplementation of preventive systems to relieve the self-neglect phenomena of the elderly living alone.

발레 무용수는 운동선수만큼이나 높은 신체 활동을 요구하고, 따라서 이들에게 부상은 매우 빈번한 일이다. 부상에 대한 정보를 파악하여 상해 예방 전략 개발에 적용하기 위해서 역학 연구는 부상의 빈도, 메커니즘, 부위 등을 심도있게 파악하는 방식으로 수행되어야 한다. 본 연구는 1년 동안 세 차례에 걸쳐 웹기반 시스템을 통해 170명의 preprofessional 발레 무용수의 다양한 부상 특징을 수집하였다. 부상 발생률 / 1,000 시간, 급성 및 만성, 재발, 부상 위치, 유형 및 메커니즘 등이 분석되었고, 통계 프로그램은 Statistical Package for the Social Sciences 버전 23.0 (IBM Corp., Armonk, NY, USA) 및 Microsoft Excel (Microsoft Corp., Redmond, WA, USA)이 사용되었다. 170명의 무용수에게서 재발을 포함하여 282개의 부상이 나타났고 노출 시간은 96,717시간으로, incidence rate(IR)은 2.92/1,000 h (95% confidence interval, 2.59-3.27)으로 나타났다. 만성 및 급성 부상은 각각 40.4%와 37.4%였고, 1차 및 2차 재발은 각각 19.5%와 2.8%였다. 발목, 발/발가락, 무릎이 가장 많이 부상을 입은 신체 부위였고, 가장 흔한 부상 유형은 염좌, 연골 손상 및 건병증으로 확인되었다. 가장 흔한 부상 메커니즘은 점프 후 착지, 도약 시 및 엉덩관절 사용이었고, preprofessional 발레 무용수의 전체 부상 중 하지 부상의 비율은 포인트 슈즈를 작용했을 때 더욱 높게 차지하였다. This study collected the ballet injury characteristics of 170 preprofessional ballet dancers. Data was collected three times a year using a web-based system. The statistical analysis was performed via Statistical Package for the Social Sciences, version 23.0 (IBM Corp., Armonk, NY, USA) and Microsoft Excel (Microsoft Corp., Redmond, WA, USA). Injury profiles and mechanisms were calculated as incidence rate/1,000 h, acute/chronic, recurrence, injury location, type, and mechanisms. The 170 dancers sustained 282 injuries over 96,717 h of overall dance exposure at an estimated incidence rate (IR) of 2.92/1,000 h (95% confidence interval, 2.59-3.27). Chronic and acute injuries were calculated at 40.4% and 37.4%, respectively. First and second recurrence were 19.5% and 2.8%, retrospectively. Ankles, feet/toes, and knees were the most frequently injured body parts. Most common injury types were included sprain, cartilage damage, and tendinopathy. The major mechanisms of injuries comprised landing after jumping, take off/jumping, and hip joint movement. The lower leg injuries occurred more frequently when dancers wore pointe shoes.

전형규 ( Jeon¸ Hyung Gyu ),정희성 ( Jeong¸ Hee Seong ),김창영 ( Kim¸ Chang Young ),이세용 ( Lee¸ Sae Yong ) 한국체육학회 2021 한국체육학회지 Vol.60 No.1

본 연구의 목적은 일상생활과 스포츠 활동 시 만성 발목 불안정성을 가진 대상의 무릎관절과 하지의 기능부전 및 통증에 대해 분석하는 것이다. 연구대상자 20, 30대 성인 남녀 60명은 발목 불안정성 정도에 따라 CAI, Coper, 대조군으로 분류되었고, 외측 발목 염좌 병력(AII), 발목 불안정성(FAAM-ADL/Sports), 무릎관절 기능부전 및 통증(IKDC), 무릎 관절염 증상(WOMAC), 하지 기능(LEFS), 신체활동량(IPAQ), 신체활동 수준(Tegner)에 대한 자가보고 설문지 작성에 참여하였다. 집단간 설문결과 비교를 위해 일원배치 분산분석과 Bonferroni 사후검정, 신체활동량 비교를 위한 교차분석, 설문결과 간 상관관계 확인을 위한 피어슨 상관분석을 실시하였다. 연구결과에 따르면 첫째, 세 집단 모두 유사한 신체활동량과 신체활동 수준을 가졌음에도, CAI 환자는 발목관절뿐만 아니라 무릎관절과 하지의 기능부전과 통증지표 점수가 높은 것으로 나타났다. 둘째, 발목 불안정성 지표는 무릎관절과 하지의 기능부전과 통증지표와 상관관계를 나타냈다. 셋째, 일상생활에서 경험하는 증상보다 스포츠 활동 시 나타나는 발목 불안정성 지표가 몸쪽관절의 환자중심 결과와 더욱 강한 상관관계를 보였다. 따라서, 발목관절의 불안정성을 해소하기 위한 중재 프로그램 적용 시, 발목관절뿐만 아니라 몸쪽관절의 기능부전과 통증이 개선되는지 확인해야 할 것이다. The purpose of this study was to analyze dysfunction and pain of knee joint and lower extremity in individuals with chronic ankle instability(CAI) during activities of daily living(ADL) and sports. A total of 60 adults were classified into CAI, Coper, and control groups according to ankle instability(AI), and conducted questionnaires including AII, FAAM-ADL/Sports, IKDC, WOMAC, LEFS, IPAQ, and Tegner activity score. One-way analysis of variance and Bonferroni post-hoc analysis, Chi-square analysis, Pearson’s correlation analysis were used for statistical analysis. The results are as follows. First, CAI patient had worse dysfunction and pain index of knee joint and lower extremity than Coper and control group. Second, AI during ADL and sports had correlation with dysfunction and pain index of knee joint and lower extremity. Third, AI during sports had a more strong correlation with patient-oriented outcomes of proximal joint than AI during ADL. Therefore, the intervention program to relieve AI should examine not only the effect on ankle joint but also improvement of dysfunction and pain index of proximal joint.

The present study aimed to investigate differences in muscle activation of peroneus longus (PL) and tibialis anterior (TA) among individuals with chronic ankle instability (CAI), copers, and heatlhy controls during walking and running. A total of 54 participants were recruited for this study. 54 participants were equally assigned to the CAI, coper, and control groups based on eligibility criteria for each group. Two surface electromyography (sEMG) were attached to PL and TA of the affected leg and 33 reflective markers were also attached to the landmark of participants based on the Visual 3D marker set. All participants were instructed to walk and run at the speed of 1.34 m/s with a boundary of 0.07 m/s and 2.68 m.s with a boundary of 0.14 m/s along the 8 m walkway. Three valid gait trials were recorded and analyzed. The full gait cycle from initial contact (IC) of the affected leg to next IC of the same leg were normalized to 100%. All sEMG data were normalized by the amplitude during maximum voluntary contraction of each participant. Ensemble curve analyses with mean ± 90% confidence intervals were conducted to identify mean differences in the amplitude of two muscles among three groups. The CAI group showed the greater amplitude of PL during walking than the coper and control groups during walking. Individuals with CAI exhibited the altered muscle activation of TA compared with copers and controls during walking. In addition, our findings indicated that there were significantly different in muscle activation of both of PL and TA between the CAI and non-CAI groups during running. Given our results, individuals with CAI need to improve joint stability using pre-activation before IC during gait.

The purpose of this study was to evaluate the prevalence rate of low back pain (LBP) in the high school students and to analyze the differences and correlations with the spinal-pelvic structural variations and disability index with LBP. The subjects are 499 high school students (236 males, 263 females: mean age, 16.38 years). They were assessed for LBP with the numerical rating scale (NRS) and for disability with the Korean version Oswestry disability index (KODI). All subjects were to take the plain radiographic examination for spinal-pelvic structural variations including thoracic, lumbar, thoracolumbar Cobb`s angle, lumbar lordotic curve, sacral slope, pelvic tilt and pelvic incidence. All subjects were divided into two groups by NRS scores (0, 1=no/minimum pain group [NMP group], 2-10=low back pain group [LBP group]). The prevalence rate of LBP of all subjects was 56.7% (n=283). NRS and total KODI scores were higher in the LBP group (3.38 cm/11.83%) than NMP group (0.07 cm/2.74%) (p<0.001). In the spinal-pelvic structural variations analysis, the thoracic Cobb`s angle was significantly high in LBP group (p <0.05), but others were shown no differences between the both groups (p>0.05). NRS had significantly positive correlation with KODI (p<0.001). NRS and KODI did not demonstrate any correlations with spinal-pelvic structural variations (p>0.05). In conclusion, this study showed high prevalence rate of LBP in the high school students, but did not show significant correlations with the spinal-pelvic structural variations and disability index.
