Problems solved by technology

However, the regulation of motor function by stimulating spinal cord nerves through transcutaneous electrical stimulation, when and where to give precise and effective electrical stimulation has not been realized.
On the other hand, the current existing transcutaneous electrical stimulation signals need to involve different electrical stimulation waveforms according to different needs and different stimulation locations; the currently commonly used electrical stimulation waveforms are bidirectional square wave pulses, and the adjustable parameters are: Current intensity, electric wave pulse width, electric wave frequency, etc. However, such electric stimulation methods and electric stimulation waveforms can only achieve the effect of inhibiting the stimulation of sensory nerves to achieve the effects of pain relief and labor pain. Neuromotor stimulation; and the system of the conventional therapy device generally does not allow the user to adjust the predetermined configuration of the electrical stimulation protocol

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a functional transcutaneous electrical nerve stimulation device for motor function regulation. Background technique [0002] Compared with electrical stimulation methods such as spinal cord electrical stimulation and epidural electrical stimulation, transcutaneous electrical stimulation has the advantages of non-implantation, safety, and convenience, and has been widely used in medical treatment. At present, the existing transcutaneous electrical nerve stimulation devices on the market at home and abroad often aim at symptoms such as insomnia, pain, and high blood pressure through electrical stimulation to sense the nerves to stimulate muscle contraction, reduce pain, and promote blood circulation. However, the regulation of motor function by stimulating spinal nerves through transcutaneous electrical stimulation, when and where to give precise and effective electrical stimulation ...
