Purpose: To determine whether performing a feint in team handball with a wide foot stance leads to a greater knee valgus angle and/or knee valgus moment.Methods: Eight women handball players performed a feint with 4 different foot stances (free and 30%, 40%, and 50% of their body height). Three-dimensional kinematics and ground reaction forces were measured during the feints. Hip abduction angle at first contact, peak vertical ground reaction force, peak knee valgus angle, and peak external knee valgus moment during the first 20% of the feint cycle were compared among the stances at 30%, 40%, and 50% of body height (ANOVA, P<0.05). In the free feint, we investigated intrasubject correlations among foot stance and hip abduction angle at first contact, peak knee valgus angle, and peak external knee valgus moment were then conducted (P<0.05).Results: When performing a feint with foot stances at 40% and 50% of body height, the subjects had significantly greater peak external knee valgus moment. Hip abduction angle at first contact was significantly correlated to peak knee valgus angle and peak external knee valgus moment.Conclusion: Training athletes to avoid wide foot stance and large hip abduction angle may reduce the risk of sustaining noncontact anterior cruciate ligament injuries.

Since students who would like to study Kampo medicine more have no opportunity to communicate each other in Northern Japanese Universities, we newly started joint study conferences held by medical students in 2013. The objectives of this paper are to report on these annually held student-based Kampo study conferences in the Hokkaido and Tohoku areas, and the ways each university studies Kampo medicine. In the conference, the students reported on their club activities. Then they studied the history of Kampo medicine and simulation of abdominal diagnosis, and performed group work on case reports together. The number of student participants in these conferences has tripled over 3 years from 18 to 58 (for a total of 111 participants). All members were satisfied with the content. And this reflects medical students' need for a wider perception of Kampo medicine, rather than a limited one gained in their university club activities. We hope this conference will play a major role in other nationwide student-based Kampo study conferences in the years to come.

Some simulation-based education tools have been introduced in Kampo medicine. However, there are only a few brief simulation tools to learn qi-blood-fluid (QBF) patterns of traditional Chinese medicine (TCM). In this study, we developed a self-diagnostic questionnaire that allows students learn TCM interviews and QBF patterns by answering the questionnaire and evaluated its reliability and validity. We extracted questionnaire items to classify six QBF patterns (qi deficiency, blood deficiency, yin deficiency, qi stagnation, blood stasis, and phlegm-fluid retention) based on some textbooks of TCM and Kampo medicine. Then we developed an initial questionnaire comprising 35 items. Fifth year medical students at Tohoku University School of Medicine answered the questionnaire of small group teaching during 2017-2020. We evaluated the accuracy of the questionnaire if compared with the diagnosis of academic supervisors. To improve the accuracy, we adjusted the questionnaire’s thresholds and created a predictive model of the patterns using logistic regression analysis. The questionnaire’s sensitivity improved by adjusting the thresholds. Logistic regression analysis resulted in a predictive model that could determine QBF patterns with the same level of accuracy as the original for 20 items overall. The results suggest that the use of a simple questionnaire with ensured accuracy may contribute to better pre-graduate education by making it easier for students to understand their own Kampo medicine patterns.

The background and course of Kampo treatment in 39 patients with uncontrollable otolaryngeal symptoms treated between April 2013 and March 2016, in the Department of Kampo Medicine at Tohoku University Hospital, were analyzed retrospectively. An improvement in overall symptoms was noted with Kampo treatment in 28 of 39 cases (71%). The commonly reported subjective symptoms included glossodynia (7 cases), postnasal drip (4 cases), oral discomfort (4 cases), dizziness (3 cases), and taste disorder (3 cases). Analysis using the classification of qi, blood, and fluid revealed that cases with qi stagnation pattern (15 of 18 cases) were effectively treated with Kampo treatment. Prior reports support our finding that smoothing qi with Kampo medicine is effective in alleviating some chronic symptoms. The symptoms improved within 6 weeks after the treatment was initiated. Therefore, a 6-week period can be considered sufficient to determine the effectiveness of Kampo medicine. Many of the patients for whom Kampo treatment was not effective had depression and domestic stress. In conclusion, Kampo treatment may be effectively used to treat uncontrollable, chronic otolaryngeal symptoms in selected cases that are unresponsive to Western medicine.
