Abstract

Understanding of the muscle characteristic mechanism involved in force generation is essential for researcher for professionals who work to improve and promote health. Surface electromyogram (sEMG) is one of the sensors that can monitor muscle characteristic. Thus, the objective of this study is to determine the relationship between sEMG signal and real dynamic force of the upper limb. Real dynamic force estimation using sEMG comprises of three main processes, which are sEMG signal data acquisition, sEMG features extraction and dynamic force validation. Muscle contraction activities was recorded using a high-performance and high-accuracy bio signal data acquisition system. Three types of upper limb muscles, which are triceps, biceps and upper brachioradialis, were involved in these measurements. Simultaneous measurements were conducted using the two types of sensors (dynamometer and sEMG) and were placed accordingly at the upper limb muscle to measure the signals at the same time domain. The sEMG signals were preprocessed using Butterworth filter (10-400 Hz), full-wave rectification, low-pass filtering (10-20 Hz) and rectification. The processed sEMG signals were compared with the conventional force sensor signals using statistical correlation test analysis. The results showed a similarity graph pattern between the sEMG signal and real dynamic force recorded using force sensor with a correlation value of 0.685.
