Problems solved by technology

In order to obtain the force and rotation angle of the big toe at a certain moment, it is necessary to synchronize the video recording equipment with the data of the touch pressure pad, which is difficult to achieve in actual operation
Therefore, it is difficult to obtain the value of the rotation angle and pressure value of the big toe at the same time, resulting in a mismatch between the bending moment and the rotation angle, which further leads to inaccurate calculation of the stiffness of the big toe

Embodiment 1

[0025] Such as figure 1 and figure 2 As shown, this embodiment includes: a pressure sensing mechanism arranged on the base, a two-dimensional platform, and a two-axis rotating mechanism with a potential detection mechanism connected to the two-dimensional platform, wherein: the two-axis rotating mechanism is fixed to the foot, The two-dimensional platform and the big toe are fixed, and the two-dimensional platform can realize the linear movement along the length direction of the big toe; direction of rotation.

[0026] The two-axis rotating mechanism includes: a foot fixing part 1 and a first rotating part 2 rotationally connected thereto, wherein: the first rotating part 2 is rotationally connected to the end of the two-dimensional platform, and a potentiometer 30 is provided at the connection , resulting in two rotational degrees of freedom.

[0027] The foot fixing part 1 is provided with a foot fixing belt 80 for fixing the foot;

[0028] The two-dimensional platform ...

Embodiment 2

[0041] This embodiment realizes the measurement of thumb stiffness and range of motion through the following operations:

[0042] 1. Mark point A at the starting point of the big phalanx and point B at the end of the big phalanx on the side of the foot, such as Figure 8 .

[0043] 2. Put the device close to the foot to be measured, and adjust the position of the foot fixture 1 so that the center of the potentiometer 30 coincides with point A on the side of the foot. The foot anchor 1 is then secured to the outside of the foot using the foot anchor strap 80 .

[0044] 3. Adjust the angle between the first rotating part 2 and the foot fixing part 1, so that the first rotating part 2 fits the outer side of the big toe.

[0045] 4. Adjust the position of the position adjustment slider 4 on the second rotating member 3 so that the center of the position adjustment slider 4 coincides with point B on the side of the foot. Then use the big toe fixing strap 90 to fix the position a...

Abstract

The invention discloses a great toe movement range and rigidity measurement device and a measurement method. The device comprises a pressure sensing mechanism and a two-dimensional platform arranged on a base, and a dual-shaft rotating mechanism which is connected to the two-dimensional platform and is provided with a potential detection mechanism, wherein the dual-shaft rotating mechanism is fixed to a foot, and the two-dimensional platform is fixed to the end of a foot great toe and is connected to the base in a sliding mode, so that a linear motion in the length direction of the foot great toe is achieved; and the dual-shaft rotating mechanism is connected to the two-dimensional platform in a rotatable mode, so that rotating motions in a vertical direction and in the rotating direction of the foot great toe are achieved. According to the measurement device, the pressure of the great toe is measured by virtue of a pressure measurement element and the rotating angle of the great toe is measured by virtue of potentiometer, so that the movement range and rigidity of great toes in various forms can be objectively and accurately measured; and the measurement device is simple to operate.

Description

technical field [0001] The invention relates to a technology in the field of medical aids, in particular to a device and method for measuring the range of motion and stiffness of the big toe. Background technique [0002] For normal and efficient walking, the hallux dorsiflexion needs to be around 65°. However, due to genetics, injury, or inappropriate shoes, the range of motion of the human hallux may deviate from the normal range of motion, manifested as too much or too little dorsiflexion of the hallux, which leads to pain in the hallux when walking and foot pain. back pain, or unsteady walking posture. In severe cases, surgery on the big toe is required to correct the degree of dorsiflexion of the big toe. Therefore, the foot and ankle surgeon needs to assess the severity of the patient based on the mobility of the big toe, and formulate a treatment plan accordingly. [0003] At present, the activity performance of the human big toe is usually described by two methods...
