  • 제주마를 이용한 경속보(rising trot)시 숙련정도에 따라 2보폭동안 기승자세를 비교 분석하여 교육과정에 응용 할 수 있는 정량적 자료를 제시한다. 참여한 피험자는 총 10명(숙련군: 5명, 미숙련군: 5명)이었고, 실험 및 분석 방법은 3차원 영상분석(Kwon3D Motion Analysis System)을 하였고, 분석변인은 국면 및 이벤트별 시간, 선 및 각운동변인이었다. 숙련군이 미숙련군에 비해 상대적으로 지지기보다 공중국면의 소요시간 비율이 더 많았고, 국면경과에 따라 더 적은 상하운동범위 속에서, 전후 및 좌우속도에서 더 일관된 속도를 유지하였고, 상하방향에서 말의 보조와 동조를 이루면서 일관된 주기를 이루면서 반동운동이 이루어졌다. 숙련군이 미숙련군에 비해 상대적으로 팔꿈치에서 더 많은 굴곡 및 국면경과에 따라 어깨의 더 많은 후방신전자세를 취하였다. 고관절과 무릎은 더 많은 전방굴곡자세를 취한 반면 발목의 경우 모두 저측굴곡의 자세를 유지하였다. 동체는 수직축에 대해 후방신전자세인 반면 미숙련군은 전방굴곡자세를 유지하였다. 즉 미숙련군의 경우 숙련군에 비해 다소 경속보에서 보조의 경과에 따라 불안한 자세를 취한 것으로 사료된다.

  • 3살 중성화된 수컷 스피츠 (8.4 kg)가 후지 파행으로 본원에 의뢰되었다. 환자는 6주전 양측 내측 슬개골 탈구 교정술을 받았다. 육안상 양측 뒷다리의 간헐적인 파행을 보였으며 신체검사에서 슬관절의 굴신전시 염발음을 동반한 중등도의 통증을 보였다. 방사선 검사상 양측 슬관절에서 연골편의 원위부 이탈과 함께 관절부종이 관찰되었다. 신체검사와 방사선검사를 토대로 양측 슬관절 골연골편의 분리와 이탈이 의심되었다. 관절경을 통해 이탈한 골연골편(우측 $1.5cm{\times}0.9cm{\times}0.2cm$, 좌측 $1.3cm{\times}0.9cm{\times}0.1cm$)을 확인하고 제거하였다. 골연골편을 제거한 후, 슬개골의 비정상적 움직임을 예방하기 위해 관절경을 통해 burr를 이용하여 층진 활차구를 성형해주었다. 환자는 수술 2주후 정상적인 보행을 하였으며 합병증을 보이지 않았다. 관절경은 개의 관절질환 진단 및 치료를 위한 효과적인 수단이다. 이를 통해 관절내 구조물을 확대해서 관찰 할 수 있고 정확한 진단을 할 수 있다. 게다가 관절경을 통한 수술은 일반적인 술부에서 나타날 수 있는 술 후 합병증을 줄여 줄 수 있다.

  • Purpose: To report the results of surgical treatment of comminuted fractures of distal humerus and to identify factors that affect the results. Materials and Methods: Thirty-two patients who were treated with open reduction and internal fixation for comminuted fracture of distal humerus were enrolled. According to the AO classification, A2.3 was 1 case, A3.2, 2 cases, A3.3, 8 cases, B1.3, 1 case, B2.3, 1 case, C2.2, 5 cases, C2.3, 4 cases, C3.2, 3 cases and C3.3, 7 cases. As fixation technique, 17 cases were fixed by double plates, 4 cases by only K-wires, 4 cases by only screws, 3 cases by K-wires and screws and 4 cases by one plate and screws. The mean age at the time of the operation was 49 years(range, $19{\sim}77$ years). The mean follow-up period was 16 months(range, $8{\sim}51$ months). Results: At the last follow-up, the mean maximum flexion was $116.4^{\circ}\;(range,\;85{\sim}140^{\circ})$ and the mean loss of terminal extension was $11.8^{\circ}\;(range,\;0{\sim}40^{\circ})$. The average Mayo elbow performance score was $91.4^{\circ}\;(range,\;55{\sim}100^{\circ})$. Overall 29 cases(91%) showed good to excellent results. The mean range of motion of extraarticular and intraarticular fracture group was $105.5^{\circ}\;(range,\;65{\sim}140^{\circ})$ and $104^{\circ}\;(range,\;55{\sim}140^{\circ})$, respectively. The average elbow score of both groups was$93^{\circ}\;(range,\;70{\sim}100^{\circ})$ and $90.7^{\circ}\;(range,\;55{\sim}100^{\circ})$. Over 90% showed more than good results. 30 cases(94%) showed complete bony union but two cases, nonunion. One case of the nonunion cases underwent replating with bone graft as revision surgery and total elbow arthroplasty was performed in the other case. At the last follow-up, 27 patients(84.4%) showed subjective satisfaction. Conclusion: Open reduction and internal fixation with appropriate surgical technique for comminuted fractures of distal humerus showed good results, which were not affected by age at the time of operation, fixation methods and anterior transposition of the ulnar nerve. Transolecranon approach may be considered as good choice for intraarticular comminuted fractures of distal humerus.

  • 본 연구의 목적은 kinesio taping 적용이 근력 향상에 미치는 영향을 직 간접적으로 관찰함으로써 운동 수행시의 상해예방 및 수행력 향상을 위한 수단으로서의 taping 요법에 대한 기초 자료를 제공하는데 있었다. 본 연구는 남자 대학생 10명을 대상으로, 근력 향상의 정도를 직접적으로 관찰하기 위하여 1RM test와 Cybex test를 실시하였으며, 생리학적 변인으로는 CK, LDH, phosphorus, ammonia, creatinine, IGF-I의 6가지 혈중 성분을 분석함으로써 피로와 근 손상의 정도를 분석하였다. 본 연구를 통하여 kinesio taping은 근력향상의 직접적인 지표(1RM, 등속성 운동능력)에는 긍정적으로 작용했지만, 85%-1RM의 웨이트트레이닝 시의 근 피로 또는 근 손상 지표물질의 농도는 유의하게 감소시키지 못함을 알 수 있었다. 하지만 본 연구의 결과만을 가지고 taping의 적용이 피로 및 근 손상 완화 효과가 없다고 판단할 수는 없을 것으로 생각된다. 왜냐하면, 본 연구에서의 피로 및 근 손상 유발 수단인 85%-1RM 웨이트트레이닝은 고강도의 운동이며 운동에 소요된 시간도 40분 정도로 장시간이지만 다양한 근육부위에 적은 반복수와 set를 적용하였기 때문에 피로 및 근 손상 지표물질의 축적이 현저하지 않았을 수 있기 때문이다. 이는 taping 적용 후 나타난 여러 혈중성분들의 감소(Creatinine 제외) 경향으로 설명할 수 있으며, 실제로 선행 연구 중 특정 대근육에 대한 반복적인 운동에 kinesio taping을 적용하여 피로 및 근 손상 완화를 입증하기도 하였다. 본 연구가 가지는 의의는 특정 동작에 있어서의 근력 향상을 중점적으로 관찰한 연구가 아닌, 전신에 대한 taping을 적용한 후 각 근육 부위에 어떠한 영향을 미치는지 다양한 관점에서 관찰하였다는 데 있다. 이후의 연구에서는 본 연구에서 관찰한 변인들 이외에도 신경계통의 변인들과의 상관관계도 함께 관찰 하는 통합적인 연구도 의의가 있다고 하겠다.

  • C. H. OH, S. N. CHOI, T. G. NAM, The Kinematic Analysis of the Tennis Flat Serve Motion, Korean Jiurnal of Sports Biomechanics, Vol. 16, No. 2, pp. 97-108, 2006. By the comparison and the analysis of the different factors during the tennis flat serve motion such as the required time per section, the movement displacement of the racket, the velocity of the upper limbs joints, the physical center of gravity, and the angle and the angular velocity of the upper limbs joints between an ace player and a mediocre player, these following results were drawn. First, the experiment result of the total time required per section in a tennis flat serve motion showed that an ace player was faster than a mediocre player by 0.4 seconds. This result suggested that it was required to increase the speed of the racket head by a swift swing to perform an effective flat serve motion. Second, the experiment result of the movement displacement of the racket in the tennis flat serve motion showed that an ace player greatly moved toward the left side on an x-axis. But both an ace and a mediocre player were shown to be at the similar points on a y-axis at the moment of the impact of the racket. An ace player was also shown to be located at a higher position on a z-axis by 0.23m. Third, the velocity of the center of gravity of an ace player was faster in every phase than that of a mediocre player in a tennis flat serve motion. Fourth, the velocity of the upper limb joints of an ace player was faster in every phase than that of a mediocre player in a tennis flat serve motion. Fifth, the experiment result of the speed of the racket head in tennis flat serve motion showed that a mediocre player was faster than an ace player in the first phase, but the latter was faster than the former in the second, third, and the fourth phases. Sixth, at the moment of impact of a tennis flat serve, an ace player had greater flexion of the angle of the wrist joints by an 11.8 degree than a mediocre player. An ace player also had greater extension of the angle of the elbow joint and the shoulder joint respectively by a 5.2 degree and a 1.4 degree with a mediocre player. Seventh, an ace player had greater angular velocity of the upper limb joints and the hip joints than a mediocre player at the moment of the impact of tennis flat serve. Eighth, an ace player was shown to have a greater change of the forward and the backward inclination (or the anterior and posterior inclination) of the upper body

  • Objectives : The purpose of this study was to evaluate and compare the cost-effectiveness of Eastern, Western, and collaborative treatments and suggest a cost-effective approach for patients with frozen shoulder pain. Methods : Using the data of fifty-two patients, treatment effectiveness was measured by CSA, SPABI, and ROM scales and changes from the baseline score were evaluated. Data source for cost estimation was based on the national health insurance (NHI) payment system. Because the price in NHI was differentiated by health care institutions, five collaborative types were considered in assessing costs. Cost-effective ratios were computed for economic evaluation. Results : Compared with Eastern treatment, collaborative and Western treatments showed better effects on CSA scale after 4 weeks' treatment. The collaborative approach was also the most effective treatment on SPADI and ROM scales. The direct cost per patient receiving Eastern treatment was less than other treatments. In general, collaborative treatment dominated Eastern and Western treatments in cost-effectiveness an analysis. However, the cost-effectiveness ratio of Eastern treatment resulted in \9,000 compared to \29,000 of collaborative treatment on SPADI. Four different indicators of ROM scales resulted in different approaches as the cost-effective treatment. Conclusions : Considering cost-effectiveness ratios, collaborative treatment was the best treatment on CSh and SPADI scales after 4 weeks' treatment. As for ROM scales, the recommended alternatives were Eastern treatment for patients with abduction and adduction disabilities, Western treatment for those with flexion disability, and collaborative approach fir those with extension disabiliry.

  • Introduction : Recent studies Suggested that there is a strong correlation between acupuncture stimulation and its related cortical activation. Anther study showed that either positive or negative BOLD effects could be observed depending on anatomical structure in acupuncture stimulation. In ttis study, we investigated a new acupoint $KI_6$ (照海), which was known as motor-related acupoint and obtained an evidence that the stimulation of $KI_6$ resulted in either negative or positive BOLD response to stimulation. Methods & Results : 1. Subjects and paradigms : Two separate stimulation paradigms were performed on five healthy (aged 22-23 yrs) in this study. First, the paradigm of acupuncture stimulation was that the acupuncture needle was inserted in acupoints $KI_6$, which is located in lateral side of the foot and then continuously twisted(補瀉를 除外한 捻轉法) for 70 seconds for 10 cycles of activation. During rest period (70 seconds), the needle was completed removed from acupoint. Total 60 cycles were performed and 10 images were obtained per cycle. Second, nonacupoint was randomly selected and the same paradigm was performed as acupoint stimulation. The stimulation protocol comprised 10 cycles of alternating. activation and rest (10 images per cycle). Total 60 cycles were performed and each cycle take about 1.5 sec for motor task. Subjects take an at least 15 minutes break before starting anther paradigm. 2. fMRI mapping : Multi-slice functional images were obtained on a 1.5T Magnetom Vision MRI scanner (Simens Medical, Erlangen, Germany) equipped with high performance whole-body gradients. The BOLD T2 * - weighted images were acquired with acho planar imaging sequence (TR = 1.2 sec, TE = 60 msec, and flip angle = $90_{\circ}$). The other sequence parameter are : FOV = 210 mm, matrix=$64{\times}128$ or $64{\times}64$, slice number=10 and slice thickness = 5 or 8 mm. the anatomic images were obtained with Spin-echo T1-weighted images. The resulting images were then anaiyzed with STIMULATE (CMRR, U. of Minnesota) to generate functional maps using a student T-test (p < 0.005) and cluster analysis. Both positive and negative response were evaluated. Conclusions : We have observed the activation of the motor cortex by stimulating motor-related acupoint ($KI_6$). Among five subjects, negative BOLD response was shown in four and positive response in one. All subjects showed positive response to conventional finger flexion-extension task. To understand the detailed mechanisms of correlation between acupuncture stimulation and BOLD fMRI changes and two typs of response, further study strongly required.
