Description

Technical Field

[0001] The present invention relates to the technical field of fine motor assessment of children's hand functions, and in particular to a method, system and application for assessing chopstick skills of preschool children's hand function development. Background Art

[0002] Hand function is a very important skill for humans. Upper limb function accounts for 60% of the whole body function, and hand function accounts for 90% of the upper limb function. Therefore, hand function plays a very important role in people's work and daily life. It is a series of activities based on the functional structure of hands and upper limbs, under the control of central nervous system and peripheral nerves, manifested by sensory, motor function, balance and coordination function of the human body.

[0003] Children's rehabilitation therapy is aimed at children with impaired physical functions and developmental delays. Through assessment, treatment and other means, it improves the development of children's motor function, cognitive function, speech and language function, so that children can recover their daily living abilities as soon as possible, integrate into society, improve their quality of life, and reduce the burden on parents and caregivers.

[0004] Among many fine motor skills of hand functions, chopstick use is a typical fine motor skill with oriental cultural characteristics. Using chopsticks is an essential operation in daily life and an important part of children's early functional movement acquisition. At present, there are many pediatric rehabilitation departments or units in China that conduct assessments and interventions on gross motor skills, fine motor skills and speech functions. There are many types of fine motor assessment scales for children's hand function evaluation, but there is still a lack of children's hand function assessment related to chopstick use, which makes it impossible to intervene in the corresponding rehabilitation measures, affecting the training and recovery of children's fine motor skills of hand functions. Summary of the invention

[0005] In order to overcome the above technical defects, the first aspect of the present invention provides a method for evaluating the chopstick skills of preschool children's hand function development, which comprises:

[0006] Step S1: Obtain the scores of each item in the scoring criteria;

[0007] Step S2: According to the chopsticks use skill evaluation formula: N=N1+N2, the total score N of the chopsticks use skill evaluation is calculated;

[0008] Step S3: Output the total score N of the chopstick use skill assessment, and output the child's hand function development level corresponding to the total score N according to the classification standard of the child's hand function development level.

[0009] Furthermore, in step S1, the scoring criteria are constructed as follows:

[0010] Step S1.1: Design a chopsticks use skill assessment scale: Design different chopsticks use tasks according to the children’s age characteristics and chopsticks use scenarios;

[0011] Step S1.2: Establishing a database: evaluating a large number of children of different ages according to the evaluation tasks, obtaining evaluation data, and forming a database of children's chopstick use skills;

[0012] Step S1.3: Formulate evaluation criteria: According to the chopstick use skill evaluation items, analyze and formulate scoring criteria, the scoring criteria are level I (77-92 points); level II (55-76 points); level III (33-54 points); level IV (9-32 points); level V (0-8 points).

[0013] Furthermore, the corresponding relationship between the total score N and the development level of children's hand function is:

[0014] (1) When the value of N ranges from 0 to 8, the corresponding level of development of children's hand function is that they are unable to use or operate chopsticks; their ability to use chopsticks to pick up, hold, and transport objects is severely limited; and they are completely dependent on caregivers in independent eating activities.

[0015] (2) When the value range of N is 9-32, the corresponding level of development of children's hand function is that they have great difficulty in using chopsticks to pick up, hold, and transport objects; they can complete some activities through efforts, but the success rate is limited; some completed activities require greater external assistance, and require continuous support, help, and / or adjustment of tools and activities.

[0016] (3) When the value of N is in the range of 33-54, the corresponding level of development of children's hand function is that they have some difficulty in using chopsticks to pick up, hold, and transport objects; the operation speed is slow, and the quality or quantity can only be limited; a small amount of external assistance is needed to prepare or adjust the operation (such as using other tools, changing the properties of objects, giving verbal prompts, etc.).

[0017] (4) When the value of N is in the range of 55-76, the corresponding hand function development level of children is that they can use chopsticks to pick up, hold, and transport most objects, but the quality and / or speed of completion are affected to a certain extent; they may have certain difficulties in using chopsticks to perform some operations and eating activities; they will use auxiliary tools (such as auxiliary chopsticks) to complete eating-related operations, but their hand abilities usually do not limit their independence in using chopsticks for daily eating.

[0018] (5) When the value of N is in the range of 77-92, the corresponding level of development of children's hand function is that they can correctly and smoothly operate chopsticks to pick up, hold, and transport objects; at most, they will only show slight limitations in hand operation speed and accuracy (or ease of operation), but these limitations will not affect the independence of using chopsticks for daily eating.

[0019] The method for evaluating the chopstick skills of preschool children's hand function development further includes step S4: recording data and comparing it with the previous data in a visual chart (if it is an initial evaluation, there is no such step).

[0020] The second aspect of the present application provides a chopsticks skill assessment system for hand function development of preschool children, which comprises:

[0021] An input module, which is used to obtain scores of each item in the scoring criteria;

[0022] Intelligent scoring module, which is used to calculate the total score N of the chopsticks use skill evaluation according to the chopsticks use skill evaluation formula: N = N1 + N2;

[0023] The output module is used to output the total score N of the chopstick use skill assessment, and output the child's hand function development level corresponding to the total score N according to the classification standard of the child's hand function development level.

[0024] Furthermore, the scoring standard is: Level I (77-92 points); Level II (55-76 points); Level III (33-54 points); Level IV (9-32 points); Level V (0-8 points).

[0025] Furthermore, the corresponding relationship between the total score N and the development level of children's hand function is:

[0026] (1) When the value of N ranges from 0 to 8, the corresponding level of development of children's hand function is that they are unable to use or operate chopsticks; their ability to use chopsticks to pick up, hold, and transport objects is severely limited; and they are completely dependent on caregivers in independent eating activities.

[0027] (2) When the value range of N is 9-32, the corresponding level of development of children's hand function is that they have great difficulty in using chopsticks to pick up, hold, and transport objects; they can complete some activities through efforts, but the success rate is limited; some completed activities require greater external assistance, and require continuous support, help, and / or adjustment of tools and activities.

[0028] (3) When the value of N is in the range of 33-54, the corresponding level of development of children's hand function is that they have some difficulty in using chopsticks to pick up, hold, and transport objects; the operation speed is slow, and the quality or quantity can only be limited; a small amount of external assistance is needed to prepare or adjust the operation (such as using other tools, changing the properties of objects, giving verbal prompts, etc.).

[0029] (4) When the value of N is in the range of 55-76, the corresponding hand function development level of children is that they can use chopsticks to pick up, hold, and transport most objects, but the quality and / or speed of completion are affected to a certain extent; they may have certain difficulties in using chopsticks to perform some operations and eating activities; they will use auxiliary tools (such as auxiliary chopsticks) to complete eating-related operations, but their hand abilities usually do not limit their independence in using chopsticks for daily eating.

[0030] (5) When the value of N is in the range of 77-92, the corresponding level of development of children's hand function is that they can correctly and smoothly operate chopsticks to pick up, hold, and transport objects; at most, they will only show slight limitations in hand operation speed and accuracy (or ease of operation), but these limitations will not affect the independence of using chopsticks for daily eating.

[0031] The preschool children's hand function development chopstick skills assessment system further includes a data storage and comparison module, which is used to record data and compare it with the previous data in a visual chart (this step is omitted if it is an initial evaluation).

[0032] The third aspect of the present application provides the application of the above-mentioned chopstick skill assessment method for hand function development of preschool children in the fine motor rehabilitation treatment of children's hand function.

[0033] Compared with the prior art, the present invention has the following innovative features:

[0034] The present invention evaluates the target children by designing a chopstick practical skill scale, performs hand function task evaluations on chopstick grasping operation, visual-motor integration and cognitive-motor integration, and statistically evaluates the scores of the evaluation scale, which can quickly, accurately and objectively evaluate the chopstick practical skills in the fine motor movements of children's hand functions, understand the normal and abnormal processes of the development of chopstick use skills in children's hand functions, and contribute to the early detection, early diagnosis and early intervention of children's hand dysfunction.

[0037] The advantages of the present invention are further described below in conjunction with the accompanying drawings and specific embodiments. Those skilled in the art should understand that the following specific description is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0038] Example 1

[0039] like Figure 1 As shown, this embodiment provides a chopstick skill assessment for hand function development of preschool children, which specifically includes the following steps:

[0040] Step 1: Design a chopsticks use skill assessment scale: According to the age characteristics of children and the scenarios of chopstick use, design different chopstick use tasks, as shown in Table 1;

[0041] Table 1 Chopstick skills assessment scale for hand function development in preschool children

[0042]

[0043]

[0044] Step 2: Establish a database: Evaluate a large number of children of different ages according to the evaluation tasks, obtain evaluation data, and form a database of children's chopstick use skills;

[0045] Step 3. Establish evaluation standards: According to the chopstick use skill assessment items, analyze and establish scoring standards. According to the scores of each individual item in the scoring standards and the chopstick use skill assessment formula, the final total score is obtained. Then, according to the classification standards of children's hand function development levels, the children's hand function development level corresponding to the final total score is obtained.

[0046] Chopstick usage skill evaluation formula: N=N1+N2.

[0047] The standards for dividing children's hand function development levels are as follows:

[0048] (1) When the value range of N is 0-8, the corresponding level of development of children's hand function is: unable to use and operate chopsticks; severely limited ability to use chopsticks to pick up, hold, and transport objects; completely dependent on caregivers in independent eating activities;

[0049] (2) When the value of N is in the range of 9-32, the corresponding level of development of children's hand function is: it is very difficult to use chopsticks to pick up, hold, and transport objects; some activities can be completed through efforts, but the degree of success is limited; some activities require greater external assistance, and continuous support, help, and / or adjustment of tools and activities are required;

[0050] (3) When the value of N is in the range of 33-54, the corresponding level of development of children's hand functions is: there are certain difficulties in using chopsticks to pick up, maintain, and transport objects; the operation speed is slow, and the quality or quantity can only be limited; a small amount of external assistance is needed to prepare or adjust the operation (such as using other tools, changing the properties of objects, giving verbal prompts, etc.);

[0051] (4) When the value of N is between 55 and 76, the corresponding level of development of children's hand function is: they can use chopsticks to pick up, hold, and transport most objects, but the quality and / or speed of completion are affected to a certain extent; they may have some difficulty in using chopsticks to perform some operations and eating activities; they will use auxiliary tools (such as auxiliary chopsticks) to complete eating-related operations, but their hand ability usually does not limit their independence in using chopsticks to eat independently in daily life;

[0052] (5) When the value of N is in the range of 77-92, the corresponding level of development of children's hand function is: they can correctly and smoothly operate chopsticks to pick up, hold, and transport objects; at most, they only show slight limitations in hand operation speed and accuracy (or ease of operation), but these limitations will not affect their independence in using chopsticks for daily eating.

[0053] Step 4: Assess the target child:

[0054] Step 4-1, conduct cognitive-motor integration assessment on the target children: assess whether the target children can hold the chopsticks correctly, including the placement of the fingers, the distance between the chopsticks, and the stability of holding the chopsticks. Assume that the target children can distinguish the front and back of the chopsticks (a1=1); the thumb, index finger, and middle finger form a control area, the two chopsticks are in the control area, and the position is relatively fixed, the wrist and elbow are off the table, and they are kept for more than 3 seconds (a2=3; and they can smoothly put down the two chopsticks at the same time according to the instructions (a3=4).

[0055] The score of a single assessment is recorded according to the scoring criteria N1=a1+a2+a3=1+3+4; for example, N1=8.

[0056] Step 4-2: Assess the target children's practical application of chopsticks: assess the children's ability to pick up objects with chopsticks, accurately control and adjust, and operate continuously, and record the score N2 of each individual assessment according to the scoring criteria; assuming that the target children can smoothly pick up all objects with chopsticks and keep them for more than 3 seconds, all 7 objects can meet this requirement (b1=2*7=14); they can smoothly pick up objects from the table with chopsticks and put them into the corresponding grooves on the horizontal surface, and all 7 objects can meet this requirement (b2=2* 7=14); can use chopsticks to smoothly pick up all the items in the box on the left side of the horizontal plane and put them in the box on the right within 60 seconds. All 7 items can meet this requirement (b3=3*7=21); can use chopsticks to smoothly pick up the items from the table and put them into the corresponding grooves. All 7 items can meet this requirement (b4=2*7=14); can use chopsticks to smoothly pick up all the items in the lower box and put them in the higher box within 60 seconds. All 7 items can meet this requirement (b5=3*7=21).

[0057] According to the scoring criteria, the score of the individual assessment is recorded as N2=b1+b2+b3+b4+b5=14+14+21+14+21; for example, N2=84.

[0058] Step 5. Evaluate children's hand function fine motor skills - chopstick use skill level: calculate the total score N according to the chopstick use skill evaluation formula, and obtain the child's hand function development level corresponding to the final total score based on the classification standard of the child's hand function development level.

[0059] According to the formula N=N1+N2, the total score N=8+84=92 can be obtained. The total score corresponds to the child's hand function development level I, which means that the child can correctly and smoothly operate chopsticks to pick up, hold, and transport objects. At most, there are only slight limitations in the speed and accuracy of hand operation (or ease of operation). However, these limitations will not affect the independence of using chopsticks for daily eating.

[0060] Example 2

[0061] like Figure 2 As shown, this embodiment provides a chopstick skill assessment system for hand function development of preschool children, which includes: an input module, an intelligent scoring module and an output module.

[0062] The input module is used to obtain the scores of each item in the scoring criteria.

[0063] The intelligent scoring module is used to calculate the total score N of the chopstick usage skill evaluation according to the chopstick usage skill evaluation formula: N1=a1+a2+a3, N2=b1+b2+b3+b4+b5, N=N1+N2.

[0064] The output module is used to output the total score N of the chopstick use skill assessment, and output the child's hand function development level corresponding to the total score N according to the classification standard of the children's hand function development level.

[0065] In actual application, the user only needs to input the scores of each individual item in the children's chopstick usage skill assessment system, and the system can immediately output the total score N of the chopstick usage skill assessment and its corresponding child's hand function development level.

[0066] It should be noted that the embodiments of the present invention have better practicability and do not impose any form of limitation on the present invention. Any technician familiar with the field may use the technical content disclosed above to change or modify it into an equivalent effective embodiment. However, any modification or equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
