Palm electric simulation control system based on elbow motion driving

Abstract

The invention discloses a palm electrical stimulation control system based on elbow motion driving. An inertia measurement module is used for acquiring an attitude quaternion of an elbow, a bending sensor module is used for acquiring a finger bending angle, a data processing module is used for summarizing the attitude quaternion and the finger bending angle and sending the summarized data to an upper computer, the upper computer sets electric simulation control parameters by periodically utilizing the received attitude quaternion and the received finger bending angle according to a preset control period, and then sends a control instruction to electrical stimulation equipment, and the electrical stimulation equipment outputs corresponding pulses to stimulate muscles corresponding to fingers to contract according to the control instruction sent by the upper computer. The palm electrical stimulation control system disclosed by the invention can automatically adjust the pulse control parameters of the electrical stimulation equipment and realize the automatic continuous stimulation of the muscles corresponding to the fingers.

Description

Technical field [0001] The invention belongs to the technical field of palm electrical stimulation control, and more specifically, relates to a palm electrical stimulation control system based on elbow motion drive. Background technique [0002] Functional Electrical Stimulation (FES) uses a certain intensity of low-frequency pulse current signals to stimulate muscle movement or simulate normal voluntary movement to improve or restore the function of the stimulated muscle. Since the American doctor Liberson first used electrical stimulation of the peroneal nerve to successfully correct the foot drop of hemiplegic patients in the 1960s, FES has been successfully used in the recovery of motor and sensory functions. Scientific research has confirmed that functional electrical stimulation can promote local blood circulation and increase capillary density, promote smooth muscle cell vascular endothelial growth factor up-regulation, and promote vascular regeneration.

Problems solved by technology

Due to limitations in movement and strength, they are unable to perform simple movements in daily life, such as hand grasping

[0004] In the past, the electrical stimulation rehabilitation and training of the hand were controlled by external commands. It will not be generated automatically, resulting in a relatively low efficiency of palm rehabilitation training. At the same time, the muscle contraction caused by the electrical stimulation generated by this method is intermittent and incoherent, which does not conform to the normal human action of reaching out and grabbing objects.
