Proportional myoelectric control can be used to activate robotic lower limb exoskeletons. A proportional myoelectric control system utilizes a microcontroller or computer that inputs electromyography (EMG) signals from sensors on the leg muscle(s) and then activates the corresponding joint actuator(s) proportionally to the EMG signal. == Background == A robotic exoskeleton is a type of orthosis that uses actuators to either assist or resist the movement of a joint of an intact limb; this is not to be confused with a powered prosthesis, which replaces a missing limb. There are four purposes that robotic lower limb exoskeletons can accomplish:〔 Ferris, D.P. and Lewis, C.L.: “Robotic Lower Limb Exoskeletons Using Proportional Myoelectric Control”, ''31st Annual International Conference of the IEEE EMBS'', pp 2119–2124, 2009〕 * Enhancement of human performance, which typically deals with increasing strength or endurance (see Powered exoskeletons) * Long-term assistance, which aims to provide impaired individuals with the ability to walk by themselves while wearing an exoskeleton * Study of human locomotion, which utilizes robotic exoskeletons to better understand human neuromuscular control, energetics, and/or kinematics of locomotion * Post-injury rehabilitation, which is intended to help an individual recover from an injury (such as a stroke, spinal cord injury, or other neurological disabilities) by wearing an exoskeleton for a short time during training in order to perform better later without the use of the exoskeleton Robotic lower-limb exoskeletons can be controlled by several methods, including a footswitch (a pressure sensor attached to the bottom of the foot), gait-phase estimation (using joint angles to determine the current phase of walking), and myoelectric control (using electromyography).〔〔Jung, J, Jang, I, Riener, R and Park, H:"Walking Intent Detection Algorithm for Paraplegic Patients Using a Robotic Exoskeleton Walking Assistant with Crutches", ''International Journal of Control, Automation, and Systems'', 10(5), pp 954–962, 2012〕 This article focuses on myoelectric control. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Proportional myoelectric control」の詳細全文を読む スポンサード リンク
