著者：Md. T. I. Khan,T. Kurita題名：EMG Signals for Co-Activations of Major Lower Limb Muscles in Knee Joint Dynamics発表情報：Biomedical Science and Engineering (International Journal) 巻: Vol. 3 号: No. 1 ページ: 9-14キーワード：EMG信号，膝関節炎，動的な分析，下肢筋肉概要：抄録：Integrity analysis of knee joint involves a detail study of several anatomical parts such as bones, cartilage, tendons etc. Any disorder or damage of these anatomical parts causes severe knee disease, like osteoarthritis (OA), which is generally found in an increasing tendency, particularly, in an aged society. Although, the reasoning of OA in knee joint is not concentrated to the present paper, however, the influences of related muscular co-activities to knee flexor-extensor actions are figured out in the present research. Particularly, the muscle reflection actions of two major skeletal muscles at knee are investigated with aging functions of participants. EMG signals have been collected from the vastus lateralis and the gastrocnemius for the dynamic movements (standing and sitting) of knee joint. Aged participants (over 60 years old) and young participants (20 -25 years old) joined the experiments. Data have been collected from both legs, however, analysis is shown only for left leg in this paper. EMG sensors and the related devices of the present sensing technique have been installed based on the instructions of Biometric Co. Ltd. Result show that the voltage amplitudes of EMG signals fluctuate largely with increasing ages and thus, the result focuses on the postural effectiveness in muscular activities for the stability challenges of knee joints in their movements.英語フィールド
