METHOD AND SYSTEM FOR CONTROLLING AN INTELLIGENT BIONIC LIMB

摘要

The present technical solution relates to the field of medical technology, more particularly to prosthetics, and even more particularly to methods and systems for controlling an intelligent bionic limb, and is intended for replacing missing limbs in humans, and also for the independent use of parts of a prosthesis in different tasks in order to improve quality of life. The present method for controlling an intelligent bionic limb includes obtaining at least one EMG signal from a patient by means of a myoelectric reading device; processing said at least one EMG signal by non-overlapping segmentation of the EMG signal; forming, for each segment obtained in the previous step, a set of EMG signal features based on the amplitude of the EMG signal for the purpose of classifying gestures; transmitting the set of EMG signal features of each segment via a data transmission channel to a control system of an intelligent bionic limb; identifying a gesture type on the basis of a set of EMG signal features using an artificial neural network; generating a control signal on the basis of the identified gesture type; transmitting the generated control signal to motors which actuate the fingers of the bionic limb; and receiving feedback from the control system of the intelligent bionic limb by receiving data from external sensors. The technical result is more accurate positioning and decision-making when grasping.
