(D) when the operating position of switching part 53 is set to the operating position corresponding with pattern D, control part 40 is stimulated to apply electricity irritation to thigh 60 or shank 70 constantly by least one in electrode section 31 ~ 33.Now, the size being supplied to the electric current of thigh 60 or shank 70 from each electrode section 31 ~ 33 is greater than the size of current of pattern C and is less than the size of current of Mode A and Mode B.Thus, apply weak electricity irritation to lower limb constantly, therefore lower limb are failure to actuate and enhance muscular strength.
(E) when the operating position of switching part 53 is set to the operating position corresponding with pattern E, stimulate control part 40 based on the testing result of sensor 41 ~ 43, electricity irritation is applied to thigh 60 or shank 70.Specifically, as (E1) below ~ (E3), carry out energising control.
(E1) stimulate control part 40 when the testing result based on joint displacements detecting sensor 41 is judged as that kneed displacement is less than ormal weight, be predicted as the load hour that knee joint is applied, do not pass through electrode section 31 ~ 33 and be energized to trans-articular flesh.On the other hand, when stimulating control part 40 to be judged as that kneed displacement is identical with ormal weight or be greater than ormal weight based on the testing result of joint displacements detecting sensor 41, be predicted as the load that knee joint is applied large time, at least one passing through in electrode section 31 ~ 33 of stimulation control part 40 is energized to trans-articular flesh.As step mode now, stimulate control part 40 both can be large and increase the quantity delivered of the electric current of each electrode section 31 ~ 33 along with kneed displacement quantitative change, or also can no matter how kneed displacement all supplies fixing electric current.
(E2) stimulate control part 40 when the testing result based on joint rotation sensor 42 is judged as that kneed rotation is less than ormal weight, be predicted as the load hour that knee joint is applied, do not rotate flesh by electrode section 31,32 to joint and be energized.On the other hand, stimulate control part 40 when the testing result based on joint rotation sensor 42, when being judged as that kneed rotation is identical with ormal weight or be greater than ormal weight, be predicted as the load that knee joint is applied large time, rotate flesh energising by least one in electrode section 31,32 to joint.As step mode now, stimulate control part 40 both can be large and increase the quantity delivered of the electric current of each electrode section 31,32 along with kneed rotation quantitative change, or also can no matter how kneed rotation amount all supplies fixing electric current.
(E3) stimulate control part 40 when the testing result based on operating state detecting sensor 43 is judged as that user does not carry out applying the action of load to knee joint, be not energized to trans-articular flesh by electrode section 31 ~ 33.On the other hand, stimulate control part 40 when the testing result based on operating state detecting sensor 43 is judged as that user carries out applying the action of load to knee joint, be energized to trans-articular flesh by least one in electrode section 31 ~ 33.In addition, apply the action of load as to knee joint, walking can be listed, action of getting out of a predicament or an embarrassing situation, stand up action and action of sitting down.
According to the present embodiment, following action effect can be played.
(1) in electrical stimulation device 1, be provided with: protector 20, it is installed on the human body comprising trans-articular flesh; And multiple electrode section 31 ~ 33, the plurality of electrode section 31 ~ 33 is arranged at this protector 20, for trans-articular flesh circulating current.
According to this structure, by trans-articular flesh circulating current, trans-articular flesh can be stimulated.This muscle contraction when trans-articular flesh is stimulated, therefore corresponding with trans-articular flesh knee joint is difficult to displacement.Thus, when under the state of electrical stimulation device 1 in user installation for when giving electric current, compared with when not supplying electric current, fixing kneed power grow, therefore, it is possible to reduce kneed dislocation.In addition, by carrying out this kneed fixing to trans-articular flesh supply electric current, therefore compared with not supplying the protector of electric current and fixing kneed type, the muscular strength of user can be suppressed to decline.
(2) in electrical stimulation device 1, as stimulation applying unit 10, the protector 20 being installed on thigh 60 and shank 70 is provided with.Protector 20 comprises thigh face portion 21, the first thigh back part 23 and the second thigh back part 24 that are installed on the position comprising trans-articular flesh in thigh 60.In addition, protector 20 comprises shank face portion 22, the first shank back part 25 and the second shank back part 26 that are installed on the position comprising trans-articular flesh in shank 70.
According to this structure, can to the trans-articular flesh circulating current of thigh 60 and shank 70, therefore with to the structure of thigh 60 with the trans-articular flesh circulating current of the one party in shank 70 compare, fixing kneed power becomes stronger.Thus, the effect reducing kneed dislocation is further increased.
(3) in electrical stimulation device 1, be provided with: joint displacements detecting sensor 41, it detects the displacement in the stretching, extension in joint and bending caused joint; And output control part 50, it controls the step mode of each electrode section 31 ~ 33 pairs of organisms.Output control part 50, based on the testing result of joint displacements detecting sensor 41, controls the step mode of each electrode section 31 ~ 33 pairs of trans-articular fleshes.
Generally, when being applied with electricity irritation to muscle, the fast muscle fiber of muscle reacts and the mobility of muscle improves.But fast muscle fiber is easy to tired, therefore large to the burden of human body when excessively applying electricity irritation.On the other hand, the burden caused knee joint is different according to kneed displacement, and bears minimum when knee joint is in neutral position shifting state.
According to the structure of above-mentioned (3), output control part 50 controls step mode based on the testing result of joint displacements detecting sensor 41, therefore, and can by stopping the fatigue reducing fast muscle fiber to knee joint energising when not needing fixing joint.In addition, even if be energized when user is unconscious as sleep procedure is medium, cause the probability of fast muscle fiber fatigue also low, therefore also can be fixed knee joint by energising when user is unconscious.Thus, the effect reducing kneed dislocation is further increased.
(4) in electrical stimulation device 1, be provided with: operating state detecting sensor 43, it detects the operating state of organism; And output control part 50, it controls the step mode of each electrode section 31 ~ 33 pairs of organisms.Output control part 50, based on the testing result of operating state detecting sensor 43, changes the current electrifying mode of each electrode section 31 ~ 33 pairs of trans-articular fleshes.
