  • the electrical stimulation is applied by the output controller 50 by each of the stimulus applying unit 10 for the right lower limb and the stimulus applying unit for the left lower limb, but for the user to select the stimulus applying unit to be used.
  • a function can also be provided.
  • the joint displacement detection sensor 41, the joint rotation detection sensor 42, and the operation state detection sensor 43 are provided in the stimulus control unit 40, but at least one of these sensors may be omitted.
  • the stimulus control unit 40 determines that the burden on the knee joint is small based on the detection result of the joint displacement detection sensor 41, the stimulus control unit 40 stops supplying current to the joint straddle muscle. It can also be changed as follows. That is, when it is determined that the knee joint burden is small, the stimulation control unit 40 can supply a smaller amount of current to the joint straddle muscle than when it is determined that the knee joint burden is large.
  • the control of the energization mode (mode E) based on the detection results of the sensors 41 to 43 and the control of the energization mode by the modes A to D are performed independently.
  • the control based on the result and the control of modes A to D can be performed together. That is, when energization based on the detection results of the respective sensors 41 to 43 becomes necessary during execution of any of the controls of modes A to D, the energization control of any of modes A to D is temporarily suspended. It is also possible to perform energization control based on the detection results of the sensors 41 to 43.
  • the stimulation control unit 40 when the stimulus control unit 40 detects that the knee joint is rotating, the stimulation control unit 40 supplies current to the quadriceps 61 and the hamstring 62 which are the joint rotator muscles of the joint straddle muscles.
  • the stimulation control unit 40 passes a current through the gastrocnemius muscle 71 which is a joint straddle muscle other than the joint rotator muscle.
  • the stimulus applying unit 10 is of a type that is worn from the thigh 60 to the lower leg 70 via the knee joint. However, a portion corresponding to the thigh 60 and a part corresponding to the lower leg 70 are provided. It can also be formed separately.
  • a type that is worn on the lower limb is provided as the stimulus applying unit 10, but instead of or in addition to this, a type of stimulus applying unit that is worn on the upper limb can be provided.
  • the following changes (A) to (D) can be made in an electrical stimulation apparatus including at least one of a stimulus applying unit attached to the lower limb and a stimulus applying unit attached to the upper limb.
  • the stimulus applying part for the lower limb is changed to a type that is worn only on the thigh 60.
  • the stimulus applying part for the lower limb is changed to a type that is worn only on the lower leg 70.
  • C Change the stimulus applying part for the upper limb to a type that is worn only on the upper arm 80.
  • the stimulus applying part for the upper limb is changed to a type that is worn only on the lower arm 90.
  • the parts corresponding to the upper arm 80 and the lower arm 90 can be formed separately.
  • the stimulus imparting unit 10 is configured as a supporter type that is worn on each of the left and right lower limbs. You can also.

Abstract

Dispositif (1) d'électrostimulation comportant un support (20) qui est porté sur des parties du corps humain comprenant des muscles trans-articulaires (61, 62, 71) qui sont des muscles franchissant des articulations. Le support (20) est muni d'une pluralité de sections (31-33) d'électrodes destinées à appliquer un courant électrique à des muscles trans-articulaires (61, 62, 71). Une première section (31) d'électrodes et une deuxième section (32) d'électrodes sont placées de façon à correspondre au muscle trans-articulaire de la cuisse (60), et une troisième section (33) d'électrodes est placée de façon à correspondre au muscle trans-articulaire de la jambe (70).
