Abstract

<P>PROBLEM TO BE SOLVED: To provide a leg dynamometer, determining objectively and accurately the effect in walking training, muscle force training or rehabilitation treatment to improve lowering of muscle force of feet and walking disability. <P>SOLUTION: In this leg dynamometer, a chair is provided on a frame placed on the floor surface, a holder is fitted to an ankle part of a right foot or a left foot of the human body when a user is seated on the chair to freely bend and stretch the lower parts from the knees of the legs, and a load measuring device is connected in the longitudinal direction between the ankle holder and the frame, thereby measuring the muscle force when the lower parts from the knees are stretched forward or bent backward. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to an apparatus for measuring muscle strength of a foot.

  Conventionally, there has been no device that can measure the muscle strength of the foot to determine the effects of walking training, strength training, or rehabilitation therapy.

  Conventionally, gait training, strength training, or rehabilitation therapy is performed to improve the symptoms of those with weak muscles of the feet or gait disorders. Since it was left to subjective judgment and it was difficult to determine an effective and accurate effect, a muscle strength measuring device for objectively judging this was required.

  The major leg muscles that control knee flexion during walking consist of the quadriceps muscles that work to stretch the knees, and the femoral flexor muscles that work to flex the knees, which cause muscle weakness. And walking becomes difficult. Therefore, the walking ability can be objectively and quantitatively determined by measuring the muscle strength for stretching the knee and the muscle strength for bending the knee.

  For this reason, a chair is provided on the frame placed on the floor, and a holder is attached to the ankle of the left or right foot of the human body so that the chair can be bent and stretched freely from the knee down, A load measuring device is connected in the front-rear direction between the ankle holder and the frame so that each muscular strength can be measured when the lower part is extended forward or bent backward from the knee.

  By using the device of the present invention when walking training, strength training, or rehabilitation therapy is performed to improve the symptoms of people with weakness of the legs or gait disorders, the effect can be objectively and quantitatively determined. Therefore, there is an effect that a more effective treatment method can be found.

  When the subject receives walking training, strength training, or rehabilitation therapy, the effect can be easily confirmed by himself / herself, which increases the willingness of the subject to receive training or treatment.

  Attach a holder to the ankle of either the left or right foot of the human body, connect a load measuring device in the front-rear direction between this ankle holder and the frame, and extend forward from the knee to the front, When measuring the muscle strength, it is desirable that the angle between the thigh and the lower limb in a horizontal state be 100 ° to 110 °.

  Similarly, when measuring the strength of the thigh flexor muscles by bending backward from the knee, it is desirable that the angle between the thigh in the horizontal state and the lower limb is approximately 90 °.

  When measuring the muscle strength by extending forward or bending backward from the knee, when connecting the load measurement device in the front-rear direction between the ankle holder and the frame, the two load measurement devices are It may be attached to the head and measured sequentially, or one load measuring device may be replaced and measured separately.

  In order to stabilize the upper body of a human body seated on a chair, it is necessary to provide a handle or handrail that can be grasped with both hands on the frame or chair on the front or both sides of the human body.

and

FIG.

Examples of the present invention will be described.
A chair 2 is provided on a frame 1 placed on the floor, and an ankle holding belt 4 is attached to the ankle portion of either the left or right foot of a human body 3 that is seated on the chair 2 so as to bend and stretch freely from the knee. The load measuring device 5 is connected in the front-rear direction between the ankle holding belt 4 and the frame 1 so as to be able to measure each muscular strength when extending downward or bending backward from the knee. To do.

  In order to stabilize the upper body of the human body 3 sitting on the chair 2, a handle 6 that can be grasped with both hands is provided on the frame 1 in front of the human body.

It is a side view which shows the case where the leg strength of a quadriceps muscle is measured by extending the front downward from the knee among the use states of the leg strength measuring apparatus of the present invention. It is a side view showing the case where the muscle strength of the thigh flexor muscle group is measured by bending backward from the knee in the usage state of the leg strength measuring apparatus of the present invention.

Claims (1)

  A chair is installed on a frame placed on the floor, and a holder is attached to the ankle of either the left or right foot of the human body so that the chair can be bent and stretched freely from the knee down. Leg strength measurement that is configured to measure each muscle strength when the load measuring device is connected in the front-rear direction between the tool and the frame and the lower part is extended forward or bent backward from the knee apparatus.
