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...
