项目摘要
This study aimed to develop a method for quantifying muscular activities during daily life and investigate its practical application. In this study, firstly, the validity and reliability of a portable EMG devise for long-term electromyogram (EMG) recording during daily life were examined The EMG data obtained using the devise linearly related to the level of force production in different joint movements, and provided stable values during a recording period of 7 hours. By the use of the devise, secondly, we investigated the differences between the upper and lower limb muscles (Exp.1) and among lower limb muscles (Exp.2) in the intensity and duration of muscular activities during daily life. In the results of the Exp.l, the total count of active phase tended to be higher in the upper limb than in the lower limb muscles On the other hand, the percentage of the integrated EMG per the period of active phase to that in MVC (%mEMGmax) was higher in the lower limb compared to the upper limb muscles. In the results of Exp.2, there were differences between muscles located in the thigh and lower leg and between their constituents in the average values of the active time and %mEMGmax. Among the muscles examined, the soleus muscle showed higher values than the other muscles in the two parameters. Thus, the present results indicated that using a portable EMG devise was useful to analyzes the muscular activities during daily life and could provide practical data for investigating the differences between muscles in atrophic changes induced by inactivity and/or aging.
本研究旨在发展一种日常生活中肌肉活动的量化方法,并探讨其实际应用。本研究首先检验了一种便携式肌电仪在日常生活中长期记录肌电的有效性和可靠性。使用该仪器所获得的肌电数据与不同关节运动的力产生水平呈线性关系,并在7小时的记录期内提供稳定的值。其次,利用该装置,我们研究了在日常生活中,上下肢肌肉之间(实验1)和下肢肌肉之间(实验2)在肌肉活动强度和持续时间上的差异。在实验1的结果中,活动期的总计数在上肢中倾向于高于下肢肌肉。另一方面,每个活动期的积分EMG占MVC的百分比(%mEMGmax)在下肢中高于上肢肌肉。在实验2的结果中,位于大腿和小腿的肌肉之间以及它们的组成之间的活动时间和%mEMGmax的平均值存在差异。在检查的肌肉中,比目鱼肌在两个参数中显示出比其他肌肉更高的值。因此,本研究结果表明,使用便携式肌电图装置是有用的,以分析肌肉活动在日常生活中,并可以提供实用的数据,研究肌肉之间的差异,在萎缩性变化引起的不活动和/或老化。
