Abstract: 表面肌电信号把神经肌肉活动和肌肉收缩联系起来,已被视为一种估计肌肉疲劳比较客观的方法,但也存在一些不足。另一方面,超声已广泛应用于医学诊断和研究,在骨骼肌方面也有不少研究报道,但还未见文献报道超声用于肌肉疲劳的估计。本文介绍一套自行开发的新的同步连续采集 B超图像、力矩和肌电信号的采集系统,并利用它对肱二头肌的肌肉疲劳进行了估计。试验表明在 30秒的肌肉疲劳过程中,肌肉厚度会以非线性的方式增加。
Surface electromyography (SEMG) possesses the features of the neuromus cular activation associated with muscle contraction, and has been used as an objective tool to evaluate muscle fatigue. But SEMG still has some disadvantages: Ultrasound has been widely used in medical diagnosis and research, and there are many reports on its study on skeletal muscles. But to the best of our knowledge, no study has been reported in using ultrasound images to characterize muscle fatigue. This paper introduced a custom-developed new sampling system which could synchronously and continuously collect B-mode ultrasound images together with torque and electromyography. The sampling system was used to evaluate fatigue of the biceps muscle. The results showed that the muscle thickness increased nonlinearly in the 30s process of muscle fatigue.
