Adjustment parameter can be adjusted to lower numerical value, when patient's degree is more serious, adjustment parameter can be adjusted to higher
Numerical value.
It optionally, can be by the product for the control signal that the adjustment parameter and signal processor calculate as the control after adjustment
Signal, output to functional electrical stimulato.The control signal after adjustment can also be directly calculated in signal processor.Example
Such as, adjusting parameter is added in the computation rule for calculating control signal, is directly calculated according to computation rule final
Control signal, output to functional electrical stimulato.Optionally, if strong side motor message is Dθ1, Ipsilateral motor message is Dθ2, in advance
If intensity regulation coefficient be k, adjusting parameter Dθ 3,Control signal is P, then preset computation rule can be：P=(Dθ1-
Dθ2)*k*Dθ3.The patient suitable for different extents is allowed the system to using signal conditioner adjusting control signal, is carried
The high applicability of the system.
On the basis of said program, the system also includes：Myoelectricity acquisition device, for acquiring strong pleural muscle electric signal.
Optionally, it can be good for side setting myoelectricity when carrying out rehabilitation training in patient and acquire signal, acquisition patient is good for the flesh when movement of side
Electric signal so that the movable information of patient is more perfect.

First signal transducer, to be arranged be second signal sensor in Ipsilateral training agent structure.It should be noted that Ipsilateral is trained
Position recovery structure in agent structure is mainly used for the malformation to training agent structure caused by Ipsilateral wrist joints sporting
It is resetted.In order to ensure patient when carrying out rehabilitation training, strong side is identical as the resistance being subject in Ipsilateral motion process, strong
It is also equipped with position same as Ipsilateral in side training agent structure and restores structure.
Further, it includes elastic element that structure is restored in the position, and the arm is fixed in described elastic element one end
On fixed frame, the other end is fixed on connecting plate, and the connecting plate is fixedly connected by screw with the finger grip structure.
Illustratively, as shown in Figure 2 a, it includes elastic element 121 and connecting plate 122 that structure 120 is restored in position.It is hit by a bullet
Property 121 one end of element be fixedly attached on the connecting rod 113 on arm fixation frame, the other end is fixed on connecting plate 122, and connect
Plate 122 is fixed on by screw 123 on the rocking bar 115 of finger grip structure.When Ipsilateral muscle receives functional electrical stimulato
When the electrical stimulation signal of output, Ipsilateral muscular movement makes Ipsilateral wrist joint generate dorsiflex or the movement of palmar flexion, and then drives Ipsilateral
Training agent structure deforms upon, that is, drives the finger grip structure rotation of Ipsilateral, and then elastic element 121 is driven to generate shape
Become, generates elastic potential energy.When movement reaches capacity, elastic element 121 discharges elastic potential energy, forces palm exercise recovery to first
Beginning state makes the deformation of Ipsilateral training agent structure reset.
It should be noted that the elasticity member of different size can be replaced according to the torque demand in different patients and rehabilitation stage
Part.In addition, the connection type that structure and arm fixation frame and finger grip structure are restored in position can be not limited to above-mentioned connection type,
It is resetted when training agent structure deforms to a certain extent as long as can realize.It is envisioned that can also incite somebody to action
Elastic element one end that position is restored in structure is fixed in finger grip structure, and other end connecting plate is fixed to arm fixation frame
On.
Further, the trained agent structure includes arm fixation frame and is connected with arm fixation frame torsion
Finger grip structure；
Restore structure setting in the arm fixation frame and the finger grip structure in the position of the Ipsilateral training device
Joining place.
In the present embodiment, it is good for the structure composition base of the structure composition and Ipsilateral training agent structure of side training agent structure
This is identical.Specifically, training agent structure 110 include arm fixation frame and finger grip structure, wherein finger grip structure with
The torsion connection of arm fixation frame.As shown in Figure 2 a, arm fixation frame including at least two fixed frames 112 and is located at fixed frame 112
Both sides and two connecting rods 113 being connected with fixed frame 112 are used for immobilized patients arm；Finger grip structure includes holding rod 114
And at least two rocking bars 115,115 one end of the rocking bar are flexibly connected with one end of the connecting rod 113,114 both ends of the holding rod
It is respectively fixedly connected with to the other end of each rocking bar 115.Fig. 2 b are the structural representations of training agent structure in the embodiment of the present invention two
Figure.The structure and connection type of trained agent structure are schematically illustrated in Fig. 2 b.
Optionally, it is good for side training agent structure and Ipsilateral training agent structure is respectively used to place patient's healthy side hand arm and trouble
Side arm.When arm fixation is positioned on the arm fixation frame of trained agent structure by patient, hand meeting nature is grabbed positioned at finger
It holds in structure.When patient needs to carry out rehabilitation training, holding rod is grasped using hand, rotation wrist joint drives finger grip structure
It moves reciprocatingly along axis of movement.Optionally, when patient needs to carry out wrist joint dorsiflex (the back of the hand is bent to forearm direction is curved) and wrist
When the training of joint palmar flexion (palm is bent to forearm direction), training agent structure can be fixed on tool by arm fixing device
Have on the platform of certain altitude, makes to train the finger grip structure in agent structure hanging, as shown in fig. le.This fixed form
