The kinesitherapy nerve of spinal cord is delivered to through electric signal, motorial nerve signal passes to neuromuscular junction, and activation muscle is produced
Power, so as to realize the motion of limbs.For paralytic, kinesitherapy nerve signal interruption is caused due to central nervous system injury
Or neuromodulation goes wrong, limb muscle receives abnormal nerve signals or does not receive motor message and lose and be activated
The function of contraction, so may result in limbs by brain control and can not realize autokinetic movement.
Stimulating current is conducted using surface electrode by FES, electric current is flowed to the kinesitherapy nerve for muscle of paralysing by skin, swashed
Kinesitherapy nerve living, so as to cause contraction of muscle, acts limbs generation, makes the Muscular reconstruction of paralysis or decline or recovers function,
Reach the purpose for the treatment of and functional rehabilitation.
Functional electrostimulation can not only maintain patient muscle's volume with recovering aid robot, and decrease muscle is powerful and prevents
Dysarthrasis, can also suppress abnormal muscle group activity, promote the plasticity of nerve and reverse rehabilitation course.
Human motion is to shrink to complete by specific muscle in fact, and current motion assistant system, is by outer mostly
Portion's equipment, directly firmly in the position for needing to move, such as crutch, wheelchair, air bag, these equipment are heavier, and are not
The muscle group for needing to shrink is directly acted on, so that the exercise to specific muscle can not be played a part of.
Southampton University of Southampton C.T.Freeman in 2007 et al. successfully develops functional electrostimulation auxiliary upper limbs health
Multiple robot rehabilitation platform, this platform upper limb rehabilitation robot is mechanical arm type convalescence device, is not wearable exoskeleton health
Multiple robot.Fang-Chen Wu in 2011 et al. are by functional electrostimulation and bilateral arm training (Bilateral arm
Training) combine for stroke patient healing hand function.These costs of equipment are higher, more heavy.

The collection of signal, and the electromyographic signal collected is transferred to the signal analysis control centre；In the signal analysis control
The heart is used to analyze the multichannel electromyographic signal being collected into, and differentiates the sports category of monitoring muscle, and according to the fortune of muscle
Dynamic type produces stimulation voltage data corresponding with the category；The muscular irritation point produces stimulus signal according to stimulation voltage data
Stimulate contraction of muscle.
Also include the first signal processing circuit, described the between the electromyographic signal collection point and signal analysis control centre
One signal processing circuit includes filtering and amplifying circuit and analog to digital conversion circuit, and the filtering and amplifying circuit is believed the myoelectricity collected
Number it is amplified filtering；Analog-digital conversion circuit as described is converted to data signal by filtered electromyographic signal is amplified.
Also include secondary signal process circuit, second letter between the muscular irritation point and signal analysis control centre
Number process circuit includes D/A converting circuit and Waveform adjusting circuit；The D/A converting circuit is used for the signal analysis control
The data signal for the stimulation voltage data that center processed is produced is converted to analog signal；The Waveform adjusting circuit is used to believe simulation
Number waveform be adjusted to the current waveform similar to nerve stimulating current.
The electromyographic signal collection point and muscular irritation point are spaced.
The band is the elastic straps of annular Wearable.
Beneficial effect
As a result of above-mentioned technical scheme, the present invention compared with prior art, has the following advantages that and actively imitated
Really：The present invention can produce corresponding stimulating current according to the motion conditions of specific muscle group so that muscle produces contraction, from
And synkinesia.Collection point and stimulation point are arranged on band by the present invention so that overall structure is more simple, and reduces into
This.
