KINEMATICS OF FOOT-SHANK COMPLEX IN “KENDO” AND ITS RELATIONSHIP WITH FOOT ARCH HEIGHT

The purpose of this study was to demonstrate 1）the joint couple of foot-shank complex in the kendo motion and 2）the relationship between the kinematic values and the foot arch height. Seventeen experienced kendo athletes volunteered to participate in the study. We instructed the participants to perform three sets of kendo strike-thrust motion with the distance of 2.2m to the target. We obtained joint kinematic data of the foot eversion-inversion and shank rotation angles to the foot during the single support phase of the kendo motion. Our result demonstrated that the foot inversion and shank external rotation movements occur during the single stance phase in experienced kendo athletes in good health. In addition, the foot arch height –length ratio was significantly related to the total range of shank rotation to the foot

Tolvaptan for Primary Aldosteronism and Autosomal Dominant Polycystic Kidney Disease: A Case Report

A 59-year-old Japanese woman was admitted for evaluation of muscle weakness. Autosomal dominant polycystic kidney disease had been diagnosed at the age of 47 years, followed by primary aldosteronism at 53 years. At the age of 58, tolvaptan was started (60 mg/day) to treat her renal disease. After 8 months of tolvaptan therapy, hypokalemia-related muscle weakness became prominent, and hypertension became refractory. Finally, treatment with low-dose tolvaptan (30 mg/day) and high-dose spironolactone (100 mg/day) normalized serum potassium and the blood pressure. Tolvaptan can induce urinary excretion of potassium in patients with primary aldosteronism, and possible mechanisms are discussed

Effects of shiftwork on lifestyle and mental health status of employees of a major Japanese electrical manufacturer

To examine the effect of shiftwork on lifestyle and mental health, a self-administered questionnaire survey was conducted among employees of a leading electrical appliances manufacturing company in Japan. The questionnaire included eight health practices recommended by Morimoto, the General Health Questionnaire-28 (GHQ-28) and demographic variables. Considering the effects of type of occupation, working hours and gender, analysis was focused on 295 male blue-collar mere employees working less than 8 hours per day and engaged in daytime work or two-shift work
