Embodiment Construction

[0050] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In addition, in the following embodiments, the drawings are appropriately simplified or deformed, and the dimensional ratios, shapes, and the like of each part are not necessarily drawn accurately.

[0051] figure 1 It is a diagram showing the overall configuration of a spasticity measuring device 10 according to an embodiment of the present invention. exist figure 1 Among them, the spasticity measuring device 10 includes a leg wearing device 12 and a leg wearing device support stand 14 .

[0052] The above-mentioned leg wearing device 12 has: for holding figure 1 The foot receiving part 20 of the foot 18 of the subject's lower limb 16 shown by the dashed line in the center; and the calf wearing part 24 for wearing on the calf part 22 . A plate-shaped member 26 containing rubber or the like is provided on the foot receiving portion 20, and a heel receiving...

Abstract

Provided is a spasticity measurement device making it possible to readily measure the degree of spasticity. A spasticity measurement device (10) is provided with a leg attachment tool (12) to which a lower leg attachment part (24) and a foot-accepting part (20) are linked so as to enable relative rotation. When the lower leg attachment part (24) and the foot-accepting part (20) are rotated in a relative fashion, the rotation is prohibited by a rotation prohibition device comprising a projection (88), an engagement recess (86), a helical compression spring (94), and other components, and the muscle contraction force acting in the direction of rotation thereof in this state is measured by a muscle contraction force measurement device constituted of a strain gauge (78), a data processing device (82), and other components. For this reason, rotating the foot-accepting part (20) and the lower leg attachment part (24) in a relative fashion causes rhythmic and repeated contraction in a test subject in whom spasticity of the lower leg (16) has been induced, while the lower leg flexor muscles remain fixed in a stretched state; thus, using the muscle contraction force measurement device to measure the muscle contraction force acting in the direction of rotation of the foot-accepting part makes it possible to easily and quantitatively measure spasticity.

Description

technical field [0001] The present invention relates to a measurement device for easily evaluating spasticity, especially spasticity of lower limbs. Background technique [0002] Spasticity is a side effect accompanying paralysis, which means muscle rigidity, inability to control leg movements, etc. Symptoms include increased muscle tension, sudden muscle contraction, deep tendon hyperreflexia, muscle spasms, scissor feet, and joint stiffness. In spasticity treatment, in addition to exercise training, drug therapy for eliminating neuromuscular disorders with drugs is generally used. [0003] In such spasticity treatment, from the viewpoint of performing appropriate treatment, it is required to grasp the patient's current symptoms and to keep track of changes in symptoms during the treatment period. In the past, the following 5-stage Ashworth scale was generally used as an evaluation of spasticity. However, since this evaluation standard depends on the feelings of doctors an...
