이 연구는 현 트렌드에 발맞추어 손상예방, 트레이닝 수업에 보다 양질의 피드백을 제공하여 보다 효율적이고 효과적인 교육프로그램 개선 및 개발하는데 목적이 있다. 부하가 증가될수록 우측 외측광근, 대퇴이두근과 좌측 내측광근, 대퇴이두근, 비복근이 활성도과 증가하였으며, 발의압력은 앞쪽이 증가하였으며 COG 좌/우 안정성이 감소하였다. 초보자들은 자신의 동작이 정확히 인지하고 수행하는지 어려움을 가지고 있으며 선수와 숙련자들은 강력한 근육을 바탕으로 보상작용을 수행해서 정확한 동작을 만들어 결국 근육의 불균형으로 인한 손상을 유발하기도 한다. 이러한 문제점을 웨어러블 기기를 이용하여 즉각적인 피드백을 제공할 수 있어 효율적인 운동지도를 할 수 있을 것으로 생각된다.

The purpose of this study was to analyze the effect of grasshopper (Oxya chinensis sinuosa) powder ingestion with/without aerobic exercise (treadmill running) on energy metabolism. To achieve this purpose, 28 Institute of Cancer Research (ICR) mice were divided into four groups: normal diet control group (CON), a normal diet with exercise control group (COEX), a grasshopper powder-supplemented diet group (GH), and a grasshopper powder-supplemented diet with exercise group (GHEX). Duration of the powder ingestion and aerobic exercise training were 6 weeks. Body weight gain ratio was not significant. Fat mass significantly decreased in GH and GHEX. There were no changes in blood glutamic oxaloacetic transaminase and glutamic pyruvic transaminase levels between groups. Glucose transporter type 2 and glucose transporter type 4 protein levels were not significantly different between groups. Fibronectin type III domain-containing protein 5 level was the highest in GHEX. AMP-activated protein kinase level significantly increased in GHEX compared to the levels in the other groups. Glycogen synthase kinase 3 beta protein level was reduced in GHEX compared to that in CON. These results suggest that grasshopper powder ingestion and endurance exercise training influence energy metabolism.

머리 위 던지는 운동선수는 전방 관절낭의 이완과 강력한 동적 안정성이 요구되므로 조금이라도 흔들리면 쉽게 견관절 통증이 유발될 수 있다. 이러한 상태가 계속되면 견관절 조직의 강한 스트레스로 손상히 발생하게 된다. 따라서 정확한 재활 프로그램을 통하여 효과적인 결과를 얻을 수 있다. 상해가 발생한 던지기 선수에서 내회전의 소실, 외회전근과 견갑근육의 약화를 교정하여 주는 것에 중점을 두고 치료한다. 추가적으로 재활에 성공한 선수에서 던지기 동작의 생역학을 평가하고 오류를 교정하면서 지속적인 교육을 시행하여 재발을 방지하고 원할한 동작을 수행하게 한다.

Chronic lateral ankle instability is a major complication of acute ankle sprains, which can cause discomfort in both daily and sports activity. In addition, it may result in degenerative changes to the ankle joint in the long term. An accurate diagnostic approach and successful treatment plan can be established based on a comprehensive understanding of the concept of functional and mechanical instability. The patients' history and correct physical examination would be the first and most important step. The hindfoot alignment, competence of the lateral ligaments, and proprioceptive function should be evaluated. Additional information can be gathered using standard and stress radiographs. In addition, concomitant pathologic conditions can be investigated by magnetic resonance imaging. Conservative rehabilitation composed of the range of motion, muscle strengthening, and proprioceptive exercise is the main treatment for functional instability and mechanical instability. Regarding the mechanical instability, surgical treatment can be considered for irresponsible patients after a sufficient period of rehabilitation. Anatomic repair (modified $Brostr{\ddot{o}}m$ operation) is regarded as the gold standard procedure. In cases with poor prognostic factors, an anatomical reconstruction or additional procedures can be chosen. For combined intra-articular pathologies, arthroscopic procedures should be conducted, and arthroscopic lateral ligament repair has recently been introduced. Regarding the postoperative management, early functional rehabilitation with short term immobilization is recommended.

Objective: Physical therapy techniques are required for patients with temporomandibular joint disorder (TMD), but the effects of treatment have not been compared. Therefore, effects of transcutaneous electrical nerve stimulation (TENS) and low level laser (LLL), which are most commonly used interventions, were compared. Design: Randomized controlled trial. Methods: Thirty-six participants with pain in the temporomandibular joint were enrolled, and 12 participants were randomly assigned to either the TENS group, LLL group, or placebo group. Each intervention was performed for a total of 6 sessions for 2 weeks. For the evaluation of the participants, the mouth opening (MO), pressure pain threshold (PPT), and stress were measured at three time periods: baseline, post-test, and follow-up at 2 weeks. Results: Significant interaction between groups according to each evaluation point was found only in PPT-masseter (p<0.05). The evaluation time point at which a significant difference appeared was at the post-test and follow-up at 2 weeks time periods. As a result of the post-test, the LLL group showed a significant improvement compared to the TENS group (p<0.05), and at 2 weeks follow-up, the TENS group showed a significant improvement compared to the placebo group (p<0.05). Conclusions: In this study, an experiment was conducted to compare the treatment effects when TENS, LLL, and placebo were given to patients with TMD. In addition, by quantitatively presenting the effect size of each treatment, this study suggests clinical use of TENS and LLL treatment for TMD.

Background: Advances in surgical techniques, implant technology, radiotherapy, and chemotherapy have increased the recovery chances of patients with bone sarcomas. Accordingly, patients' expectations on life quality have also increased, highlighting the importance of objective evaluation of the functional results of reconstruction. Methods: Thirteen patients with distal femoral endoprosthesis, who had been followed for an average of 2.9 years were evaluated. Postural stability, daily energy expenditure, muscle power, and range of motion were the four parameters analyzed in this study. The Musculoskeletal Tumor Society (MSTS) score and Toronto Extremity Salvage Score (TESS) were used to assess postoperative function and examine correlations with other parameters. Results: Patients had sedentary activities in 84% of their daily lives. They exhibited a slower speed in the walk across test and a higher sway velocity in the sit-to-stand test (p = 0.005). MSTS scores were significantly correlated with the daily energy expenditure and walking speed. Conclusions: Objective functional results acquired from various clinics will provide significant data to compare reconstruction techniques, rehabilitation protocols, and surgical techniques. In this way, it will be possible to satisfy the expectations of patients that increase in relation to enhanced recovery.

Purpose: To investigate the satisfaction of students majoring in physiotherapy and to confirm a change of perception on employment decisions after clinical training. Methods: Structured questionnaires were distributed to 500 undergraduate physiotherapy students in 2014. Data from 462 respondents were analyzed using the Mann-Whitney, Kruskal-Wallis, Wilcoxon's signed-rank, stepwise regression, and independent samples t tests. Design: Cross-section study Results: The satisfaction and perceptions of employment decision increased post-clinical training among physiotherapy students who hoped to find employment. After clinical training, the desired employment venues also changed: fewer students desired to work in rehabilitation centers and secondary hospitals, and more desired to work in university hospitals, general hospitals, public welfare centers, and the industrial company health facilities. There were changes in the preferred fields of those who hoped to find employment in the field, as well. There was decreased interest in clinical electrophysiology, sports, and women's health, and increased interest in neurology, orthopedics, and pediatrics. Conclusion: The results of this study confirmed that clinical training changes student' employment decisions and affects their desire to enter specific fields.
