Embodiment 1

[0048] Such as Figure 1-Figure 3 As shown: the present embodiment provides a multi-posture grip strength sensory testing device 100, comprising a grip strength measurement structure 1, a joint angle measurement structure 2, a pressing plate 3 and a controller 4, the grip strength measurement structure 1 includes a pressure sensor 5, and a joint angle measurement structure Measuring structure 2 comprises inertial attitude sensor 6, and pressing plate 3 is connected with pressure sensor 5, and pressure sensor 5 is used for measuring the pressure that pressing plate 3 is subjected to, and controller 4 is electrically connected with pressure sensor 5 and inertial attitude sensor 6 respectively, and inertial attitude sensor 6 is used to measure changes in joint angles.

[0049] In this embodiment, the pressure sensor 5 is electrically connected to the controller 4 through an analog-to-digital converter 7 .

[0050] In this embodiment, the controller 4 is electrically connected to...

Embodiment 2

[0054] This embodiment provides a test method for grip strength sense and position sense, including grip strength sense test and upper limb position sense test.

[0055] Such as Figure 4 and Figure 5 As shown, the grip strength test uses the force reproduction method test, including the following steps:

[0056] Step a1, the subject sits on the test chair in a sitting position, the torso is fixed by straps, and the movement compensation of other joints to the upper limbs is removed;

[0057] In step a2, the subject holds the multi-posture grip strength sensory testing device 100, and conducts the maximum voluntary isometric contraction grip test, and obtains the maximum voluntary isometric contraction strength, which is denoted as MVIC (maximal voluntary isometric contraction);

[0058] In this embodiment, in step a2, when performing the maximum voluntary isometric contraction grip strength test, the subject is required to have a neutral shoulder joint, 90° elbow flexion, ...

Abstract

The invention discloses a multi-posture gripping force sense testing device and a gripping force sense and position sense testing method, and relates to the technical field of physical testing, the posture gripping force sense testing device comprises a gripping force measuring structure, a joint angle measuring structure, a pressing plate and a controller, the gripping force measuring structure comprises a pressure sensor, the joint angle measuring structure comprises an inertia attitude sensor, the pressing plate is connected with the pressure sensor, the pressure sensor is used for measuring pressure borne by the pressing plate, the controller is electrically connected with the pressure sensor and the inertia attitude sensor, and the inertial attitude sensor is used for measuring the change of the joint angle. The gripping force sensation and position sensation testing method comprises gripping force sensation testing and upper limb position sensation testing. The upper limb joint angle and the gripping strength can be obtained at the same time, and the upper limb posture in the gripping strength sense test process and the gripping strength of the hand in the upper limb position sense test process can be accurately measured.

Description

technical field [0001] The invention relates to the technical field of physical fitness testing, in particular to a multi-posture grip strength sense test device, grip strength sense and position sense test methods. Background technique [0002] Practitioners of various types of work always hold tools in a certain upper limb posture to perform various operations during work. The smooth progress of this operation requires, on the one hand, accurate application of grip force (grip force sense) under different upper limb postures; Two inseparable aspects of an operation that occur simultaneously. Existing studies on upper limb position sense have not considered hand grip strength, and studies on hand grip strength sense have not considered upper limb posture. Since the grip strength will affect the range of motion of the upper limb joints, the range of motion of the upper limb joints measured after the grip strength test cannot represent the range of motion of the joints duri...
