1. A training device for training a limb, the training device comprising:
a switch being manipulated with the limb; and
a load reliever generating a counter force against a weight of the limb in a manner allowing the limb to move upward and downward.
2. The training device according to claim 1, further comprising a vibratory stimulator giving a vibratory stimulus to the limb in response to manipulation of the switch.
3. The training device according to claim 1, further comprising an electrical stimulator giving an electrical stimulus to the limb with a current value not generating a motion of a joint.
4. The training device according to claim 3, wherein the electrical stimulator gives the electrical stimulus to the limb in response to manipulation of the switch.
5. The training device according to claim 1, wherein the load reliever includes
an attachment to be attached to the limb,
a wire pulled upward from the attachment, and
a tensioner that generates a counter force against the weight by
applying a tensional force to the wire in a manner allowing the attachment to move upward and downward.
6. The training device according to claim 5, wherein the tensioner applies the tensional force by potential energy stored in a passive element.
7. The training device according to claim 6, wherein the tensioner applies the tensional force by elastic energy stored in a spring element.
8. The training device according to claim 7, wherein the tensioner applies the tensional force by elastic energy stored in a constant load spring element.
9. The training device according to claim 8, wherein the constant load spring element includes a rotatable reel and a sheet spring generating a force against the rotation of the reel.
10. The training device according to claim 5, wherein the load reliever includes a tension sensor for the wire, and an adjustor for the tensional force.
11. The training device according to claim 1, further comprising an adjustor for adjusting a position of the switch.
12. The training device according to claim 11, further comprising an anti-drop stopper, wherein
the adjustor for adjusting the position of the switch is an adjustor for adjusting a height of the switch, and
the anti-drop stopper generates a counter force against descending of the switch when adjusting the height.
13. The training device according to claim 12, wherein the anti-drop stopper includes a winding up shaft and a sheet spring wound around the winding up shaft, and
the sheet spring generates a counter force against the descending of the switch.
14. The training device according to claim 1, further comprising a chest stopper restricting movement of a chest of a patient having the limb.
15. The training device according to claim 1, further comprising a monitor presenting information related to the training.
16. The training device according to claim 5, further comprising
a pulley higher than the attachment and run about by the wire, and
an adjustor for adjusting a position of the pulley along horizontal direction.
17. A training device for training a limb, the training device comprising:
a switch being manipulated with the limb; and
a means for generating a counter force against a weight of the limb in a manner allowing the limb to move upward and downward.
18. The training device according to claim 17, further comprising a means for giving a vibratory stimulus to the limb in response to the switch.
19. The training device according to claim 17, further comprising a means for giving an electrical stimulus to the limb with a current value not generating a motion of a joint.
