Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a motion capture glove. Background Art
[0002] Progressive cognitive dysfunction caused by Alzheimer's disease (AD) seriously threatens the health of the elderly, and its development is a continuous and progressive process. Mild cognitive impairment (MCI) is between normal aging and dementia, and has bidirectional conversion. The current consensus emphasizes the early identification of MCI people to delay the progression of cognitive impairment, that is, moving the threshold forward. The decline in fine motor ability has already occurred in the MCI stage, which is an early manifestation of motor function defects in patients with cognitive impairment and the initial link of physical function decline to disability. Therefore, understanding the changing characteristics of MCI patients' fine motor ability is expected to accurately identify MCI patients earlier, and then explore precise and effective motor intervention targets to delay the progression of the disease.
[0003] Age-related cognitive impairment is a continuous and progressive process, covering MCI and dementia. Once entering the dementia stage, the disease progresses relatively quickly, and there is no effective means to reverse its progress. MCI is an intermediate state between normal aging and dementia, with bidirectional conversion. The current consensus emphasizes that the focus of research on cognitive impairment should be shifted from dementia to the MCI stage. However, due to the hidden and complex occurrence and development of cognitive decline in the elderly, it is urgent to develop an efficient and accurate screening-assessment system to identify MCI people as early as possible.
[0004] As MCI progresses to dementia, the quality of life of the elderly gradually declines, mainly reflected in the ability to carry out daily activities, such as writing, housework, cooking, and using electronic devices. The key to these behaviors is the ability to control fine motor skills. Previous studies have confirmed that the ability to control fine motor skills and executive ability are one of the dimensions that reflect cognitive function, and the decline in fine motor skills is correlated with the progression of cognitive dysfunction. Among the multiple dimensions in the field of cognitive function, executive ability has the strongest correlation with hand motor function. Studies have found that the decline in fine motor skills and executive ability of the elderly has already appeared in the MCI stage, which is an early manifestation of motor function defects in patients with cognitive impairment. If the characteristic changes in fine motor skills of MCI patients can be discovered early, it will be possible to accurately identify MCI patients earlier and provide the possibility of exploring motor intervention targets. So far, there is still a lack of clear description of the hand movement characteristics and detailed changes in MCI patients during task execution, and there is no research to answer which details of fine motor skills can reflect the decline in cognitive function in MCI patients. Traditional hand function assessment methods represented by the Jebsen hand function test and the Purdue nail board test are cumbersome, time-consuming and labor-intensive, and difficult to depict the detailed characteristics of movement. The ecological validity of the acquired data is low, and it is difficult to reflect cognitive function. Therefore, it is of great practical significance to develop and establish a digital assessment system that can capture the fine motor details of the elderly and further explore the motor defect characteristics of MCI patients.

The motion capture glove can be loaded with 6 inertial measurement units 10, which are used to capture fine hand movements. It is worth noting that the present application mainly protects the structure and shape of the motion capture glove, and the inertial measurement unit 10 is not a part of the motion capture glove itself.
[0035] In the present embodiment, preferably, the first accommodating pocket 1, the second accommodating pocket 2, the third accommodating pocket 3, the fourth accommodating pocket 4, the fifth accommodating pocket 5 and the U-shaped card slot 8 are respectively provided with marking structures to distinguish each other, and each marking structure has a different color or a different shape. At the same time, corresponding marking structures are also provided on the six inertial measurement units 10 so that they can be aligned one by one during installation, which is convenient for users, especially the elderly, to identify them accordingly.
[0036] For example, the marking structures are labels of different colors, which are respectively adhered to the surfaces of the first accommodating pocket 1 , the second accommodating pocket 2 , the third accommodating pocket 3 , the fourth accommodating pocket 4 , the fifth accommodating pocket 5 and the U-shaped slot 8 .
[0037] A green label is pasted or sewn on the first receiving pocket 1;
[0038] A yellow label is pasted or sewn on the second receiving pocket 2;
[0039] A blue label is pasted or sewn on the third storage pocket 3;
[0040] A red label is pasted or sewn on the fourth receiving pocket 4;

Since certain hand movements need to be completed during the test, such as bending the fingers, etc., when multiple tests are performed, the edges of the finger sleeves may shift and wrinkle sometimes, thereby causing the positions of the inertial measurement units 10 in each pocket to move. The positions of the thumb sleeve, the index finger sleeve, the middle finger sleeve, the ring finger sleeve and the pinky finger can be adjusted at any time through the stretch ring 6 to ensure the accuracy of the test.

[0049] In this embodiment, preferably, the circular fitting portion 7 is a hard patch embedded in or sewn on the upper surface of the wearable body.
[0050] In this embodiment, preferably, the circular fitting portion 7 is connected with a U-shaped slot 8, which is distributed transversely, and the opening of the U-shaped slot 8 is distributed toward the thumb sleeve. The inertial measurement unit 10 can slide sideways into the U-shaped slot 8 to complete positioning.
[0051] Specifically, the circular fitting portion 7 includes: a hard patch and an adhesive pressure ring; the hard patch is arranged on the upper surface of the wearable body (the back of the hand), and the adhesive pressure ring is pressed around the hard patch and adhered to the upper surface of the wearable body. The hard patch is integrally connected with a U-shaped card slot 8, which is distributed laterally, and the outer surface of the U-shaped card slot 8 has an arc-shaped surface, the upper edge of the slot wall of the U-shaped card slot 8 has a circle of clamping planes, and the lower edge of the slot wall of the U-shaped card slot 8 has a circle of concave curved surfaces. This design is more conducive to the plugging and unplugging of the inertial measurement unit 10. Of course, the design here is not limited and can be flexibly adjusted according to actual needs.
[0052] In this embodiment, preferably, the wristband adhesive structure 9 includes: a first adhesive tape and a second adhesive tape; the first adhesive tape is sewn on the upper surface of the wrist of the wearable body; one end of the second adhesive tape is sewn on the side edge of the wrist of the wearable body, and the second adhesive tape can be detachably attached to the first adhesive tape. Specifically, a notch is provided on the side edge of the wrist of the wearable body; one end of the second adhesive tape is sewn on one side of the notch, and the other end of the second adhesive tape can cover the outside of the notch and be detachably attached to the first adhesive tape.
[0053] The method of using this embodiment is as follows: first, install the six inertial measurement units 10 in the first storage pocket 1, the second storage pocket 2, the third storage pocket 3, the fourth storage pocket 4, the fifth storage pocket 5 and the U-shaped card slot 8 respectively; then, wear the motion capture glove on the patient's hand and fix the wristband adhesive structure 9.
