As an example, the target-reaching movement of index finger, which is a basic functional action of index finger in the daily life of hUman beings, were experimentally investigated. In the experiment five healthy male subjects were asked to perform three target-reaching movement tasks Which have different indices of difficulty. All movements were recorded by a 3-D motion analysis system. Later, their motion qualities were measured with these evaluation metrics. The results showed that these indices are reasonable and have potential applications to biomedical engineering.展开更多

It is known to be associated more frequently with men than women, particularly in the premenopausal age range. The goal of this study is to evaluate gender differences among Korean patients diagnosed with SBD. This study included 309 patients who visited our Sleep Clinic due to sleep-related symptoms and were diagnosed with SDB by overnight polysomnography (PSG). We analyzed age, gender, body mass index, various PSG indices including sleep stages, apnea-hypopnea index (AHI) and AHI ratio in rapid eye movement (REM) versus non-REM (NREM) sleep stages (R:N ratio). Of those 309 patients diagnosed with obstructive sleep apnea, 217 (70.2%) were men (mean age 51.05 ± 12.64 years) and 92 (29.8%) were women (mean age 64.53 ± 10.43 years). The mean AHI during total sleep time was 30.34 ± 21.17 in men and 21.47 ± 17.14 in women (P P P = 0.402). REM SDB with R:N ratio higher than 2.0 was more frequently observed in women than in men, 34.8% (32/92) of women, compared with 11.9% (26/217) in men (P 60 years old. These findings suggest the possibility of different pathophysiologic mechanisms of SDB between genders and also between NREM versus REM sleep, which can be partly explained by the influence of female sex hormones.展开更多
分析体质量指数(body mass index,BMI)与性别因素对大学生功能性动作筛查(function movement screens,FMS)的影响,为提高大学生身体素质和运动损伤的预防提供客观依据。结果:男生组BMI与FMS评分呈负相关(r=-0.335,P<0.01);女生组BMI...分析体质量指数(body mass index,BMI)与性别因素对大学生功能性动作筛查(function movement screens,FMS)的影响,为提高大学生身体素质和运动损伤的预防提供客观依据。结果:男生组BMI与FMS评分呈负相关(r=-0.335,P<0.01);女生组BMI与FMS评分呈极弱相关(r=0.099,P>0.05);男生和女生BMI标准组与超重组FMS得分组间差异均有统计学意义(P<0.01);男生组FMS总分(15.96±2.02)分小于女生组(16.60±1.25)分(P>0.05);男生在深蹲、稳定性俯卧撑和旋转稳定性上要好与女生;女生则在跨栏步、前后分腿蹲、肩关节灵活性、主动直膝抬腿上均好于男生。结论:大学生BMI与FMS的之间存在相关性且存在性别上的差异;大学生FMS测试总评分无性别差异,但在单项评分上有性别差异。不同BMI分组和FMS评分相结合能够较为客观地反映大学生这个年龄阶段的整体运动能力,可为培养大学生运动习惯和大学生体育教学提供补充参考。展开更多
