Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training, and in particular to a movement development evaluation and training system for children with motor development retardation. Background Art

[0002] Motor Development Delay (MDD) refers to a delay in a child's motor skill development, typically manifesting as slower motor development, poor coordination, and abnormal posture compared to peers. MD is often caused by a variety of factors, including congenital disorders, brain damage, immature development, and a lack of external stimulation. It is often accompanied by other developmental issues, such as delayed cognitive development, language impairment, poor balance, and adaptive behavior disorders.

[0003] In traditional rehabilitation training, passive or active physical therapy methods are mainly relied upon, aiming to correct children's movement abnormalities through mechanical movement training. However, the effectiveness of such treatment methods is often limited, and it is easy to lead to low interest in training and poor compliance among children, as well as long treatment cycles and slow results. With the diversification of children's rehabilitation needs, traditional rehabilitation methods have certain shortcomings in terms of training content, fun, and personalization. Therefore, existing technologies are in urgent need of innovation, especially in improving children's motor development, intellectual development, balance ability, and adaptive behavior, which require the use of more innovative and diversified training methods.

[0004] In recent years, the application of virtual reality (VR) technology in rehabilitation medicine has made significant progress. VR technology can create an immersive, interactive environment, providing users with a truly immersive experience. This unique advantage gives it a unique advantage in pediatric rehabilitation training. Through VR technology, children can perform various motor tasks in a virtual environment. The system captures the child's movement data in real time, generates feedback, and adjusts training content, effectively improving children's training motivation and effectiveness. Research has shown that VR technology can not only improve children's motor coordination but also enhance their cognitive and social abilities through interaction with the virtual environment.

[0005] At the same time, the application of multisensory stimulation in pediatric rehabilitation has also garnered widespread attention. Multisensory stimulation involves stimulating children through multiple sensory channels, including vision, hearing, touch, smell, and vestibular senses, to stimulate neural responses and enhance the plasticity of the nervous system. Research has shown that sensory stimulation can significantly promote brain development in children, improving their attention, motor coordination, and cognitive abilities. For example, visual stimulation can help improve visual tracking, auditory stimulation can enhance language comprehension, and olfactory and tactile stimulation can enhance perception and motor dexterity.

[0006] Although virtual reality technology and multisensory stimulation have achieved some research results in the rehabilitation of children with motor delays, current technical solutions often focus on the application of a single technology and lack effective interdisciplinary integration. Existing technologies are often still limited to training a single sense in multisensory stimulation, lacking comprehensive, multidimensional sensory stimulation. Moreover, the application of virtual reality technology in pediatric rehabilitation is mostly limited to highly entertaining interactive games, lacking sufficient targeted and personalized training programs, and difficult to adjust to the specific developmental situation of the child.

[0007] Furthermore, while virtual reality technology can provide an immersive experience, for children with motor developmental delays, the training content still needs to be made more engaging and interactive to stimulate children's participation and improve their compliance. While some existing systems combine virtual reality with rehabilitation, these approaches generally lack adequate consideration for individual child differences, require long training cycles, and have limited effectiveness.

[0008] Therefore, in view of the deficiencies in the prior art, the present invention proposes a motor development evaluation and training system for children with motor developmental delays to solve the above problems. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0052] In order to more clearly illustrate the technical solutions in the present invention or the prior art, a brief introduction is given below to the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0053] Figure 1 This is a system block diagram of a motor development evaluation and training system for children with motor developmental delays according to the present invention. DETAILED DESCRIPTION

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0055] Example: See Figure 1 As shown, the present invention provides a motor development assessment and training system for children with motor developmental delays. This system aims to provide comprehensive motor development training, assessment, and feedback for children with motor developmental delays by combining multisensory stimulation with virtual reality technology, thereby improving their motor and intellectual development, balance, and adaptive behavior. This embodiment describes the system's structure and operating principles in detail, covering all technical aspects.

[0056] The system consists of multiple modules, the core of which are the multi-sensory stimulation module, the virtual reality training module, the assessment module, and the data storage module. Each module has a clear function in the system and works together to achieve comprehensive training and assessment of children's motor development.

[0057] First, in the multi-sensory stimulation module, the system promotes sensory development by providing visual, auditory, olfactory, tactile, and vestibular stimulation. In the visual stimulation section, children are trained using devices such as colorful bubble fish tubes. The vibrant colors and dynamic effects of the bubble fish tubes effectively attract children's attention, stimulate their visual nerves, and promote eye movement reflexes. Auditory stimulation is provided through songs and instrumental performances, stimulating children's auditory perception and enabling them to better perceive and respond to external sounds. Olfactory stimulation uses scents such as orange and lavender essential oils, which are applied to children's foreheads and behind their ears to stimulate the olfactory system and increase their sensitivity to odors. Tactile stimulation, through devices such as ocean ball pools and tactile mats, helps children improve fine motor skills and enhance hand-eye coordination through activities such as grasping and building blocks. Vestibular stimulation uses devices such as rocking chairs and rainbow tunnels to simulate imbalance, stimulate children's sense of balance, and strengthen their ability to balance.

[0058] The virtual reality training module uses VR technology to provide children with an interactive virtual environment in which they can perform various sports tasks, such as jumping, squatting, and avoiding obstacles. The virtual environment obtains the child's real-time motion data through somatosensory sensors and displays the game screen through a display device. Children can interact with the tasks in the virtual environment during training. The system provides real-time feedback based on the child's movement performance, thereby guiding the child to make correct movements and promoting their development by continuously increasing the intensity of exercise. The intensity of training is calculated using the following formula:

[0059]

[0060] Among them, M(t) is the actual motion data at the current moment, M max is the maximum exercise intensity value set by the system, and α(t) is the percentage of exercise intensity at the current moment. Through this dynamic adjustment system, the training intensity can be ensured to be within a reasonable range to avoid overtraining or undertraining. The evaluation module is another important component of this system, which is used to regularly evaluate children's motor development, intellectual development, balance ability and adaptive behavior. In order to evaluate children's motor development, the system uses the Peabody Developmental Motor Scale (PDMS-2), which includes the assessment of gross motor and fine motor skills, and reflects the child's motor development level by calculating the gross motor development quotient (GMQ) and the fine motor development quotient (FMQ). The specific algorithm is:

[0061]

[0062] Intellectual development is assessed using the Gesell Developmental Diagnostic Scale (GDS), and developmental quotient (DQ) is calculated by the ratio of intellectual development score to actual age:

[0063]

[0064] In addition, the Berg Balance Scale (BBS) is used to assess children's balance ability, and the sum of the scores directly reflects the child's balance ability. Adaptive behavior is assessed using the Child Adaptive Behavior Assessment Scale (CABS), and the adaptive ability quotient (CAQ) is finally obtained:

[0065]

[0066] The evaluation results provide personalized feedback for each child's training and can ensure the effectiveness and targeting of the training by adjusting the training content in real time.

[0067] The system also includes a data storage module for storing children's assessment data and training records. The system generates personalized training reports based on data analysis. The data storage module tracks children's motor development progress in real time and updates their motor development curves. Parents and rehabilitation trainers can access children's training data and assessment results at any time through the system interface and adjust training plans as needed.

[0068] This system works by combining multisensory stimulation with virtual reality technology to provide children with personalized, comprehensive training programs. By continuously adjusting training intensity, providing real-time feedback, and conducting regular assessments, the system effectively promotes children's motor and intellectual development, enhancing their balance and adaptability. Parents and rehabilitation trainers can monitor and manage children's training progress in real time through the system, ensuring continuous improvement in training effectiveness.

[0069] During the system's implementation, the combination of virtual reality technology and multi-sensory stimulation has enriched and enhanced traditional rehabilitation training methods, while also increasing children's enthusiasm for participating. Through training with this system, children can experience richer sensory stimulation in a virtual environment, accelerating their motor and intellectual development, improving their balance, and ultimately fostering improved adaptive behavior.

[0070] To validate the effectiveness of the present system for evaluating and training motor development in children with motor developmental delays, the following example describes its application in a real-world clinical setting. This example uses "Xiao Ming," a three-year-old child with motor developmental delay, as an example to demonstrate how the system can be used to train and assess movement, intellectual development, balance, and adaptive behavior.

[0071] Xiao Ming is a 3-year-old child diagnosed with motor developmental delay, which is manifested by unsteady gait, poor gross motor skills, and some cognitive developmental delay.

[0072] 1. Before applying this system, we first conduct a comprehensive preliminary assessment of Xiao Ming to develop a plan for subsequent personalized training.

[0073] Step 1.1: In the training room of the hospital's rehabilitation department, the rehabilitation therapist used the Peabody Developmental Motor Scale (PDMS-2) to assess Xiao Ming's gross and fine motor skills. The results showed that Xiao Ming's gross motor skills scored 72 out of 100, and his fine motor skills scored 68. Next, the Gesell Developmental Diagnostic Scale (GDS) was used to assess Xiao Ming's intellectual development, resulting in a score of 68, indicating that his intellectual development lags behind that of children of the same age. Xiao Ming's balance ability was assessed using the Berg Balance Scale (BBS), with a score of 26, indicating some balance problems. Finally, the Child Adaptive Behavior Assessment Scale (CABS) was used to assess Xiao Ming's cognitive function, independence, and social self-control. His adaptive ability score was 55, indicating that Xiao Ming had limited independence in daily life.

[0074] Step 1.2: All assessment data is stored in the system and a preliminary report is generated. The report details Xiaoming's baseline data on motor development, intellectual development, balance, and adaptive behavior, providing a basis for the subsequent training plan.

[0075] 2. After completing the initial assessment, Xiao Ming began systematic, personalized training. Based on the assessment report, the rehabilitation therapist developed a training plan tailored to Xiao Ming using a systematic multisensory stimulation module and a virtual reality training module.

[0076] Step 2.1: In the training room, Xiao Ming is taken to a dedicated training area. First, multi-sensory stimulation training is carried out:

[0077] Visual stimulation: The therapist placed a brightly colored bubble fish tube about 1 meter in front of Xiao Ming. The movement of dynamic bubbles attracted Xiao Ming's attention, stimulated his visual perception, and promoted the stimulation of eye movement reflex.

[0078] Auditory stimulation: The therapist played cheerful children's songs and held a small bell in his hand to guide Xiao Ming to grab and touch it, stimulating his hearing and motor coordination.

[0079] Olfactory stimulation: After confirming that Xiao Ming had no allergic reaction, the therapist applied diluted orange essential oil on Xiao Ming's forehead and guided him to conduct olfactory training to help him enhance his olfactory perception ability.

[0080] Tactile stimulation: Xiao Ming was guided to the ball pool for standing and stepping training. At the same time, the therapist used building blocks and other tactile toys to guide Xiao Ming to grasp, improving his fine motor skills and hand-eye coordination.

[0081] Vestibular stimulation: The therapist places Xiao Ming on a rocking chair and gently tilts it. By creating an unbalanced state of the body, the therapist stimulates his vestibular system and enhances his balance ability.

[0082] The training time for each sensory stimulation is about 10 minutes. Through this comprehensive multi-sensory stimulation, Xiao Ming can comprehensively improve his sensory response and motor skills.

[0083] Step 2.2: After completing the multisensory stimulation training, the therapist puts on Xiao Ming's VR headset and body sensors. The system uses VR technology to create a simulated virtual environment that includes obstacles and movement tasks.

[0084] Virtual tasks: Xiao Ming needs to perform exercises in virtual reality, such as squatting, jumping, and bypassing obstacles. After each task is completed, the system will evaluate Xiao Ming's performance through sensor data.

[0085] Real-time feedback: The system calculates the error e(t) = T(t) - M(t) based on Xiaoming's performance in real time, where T(t) is the target movement and M(t) is the movement Xiaoming actually performs. Based on the feedback error, the system adjusts the task difficulty, gradually adapting the training to Xiaoming's athletic ability.

[0086] Dynamically adjust the training intensity: According to Xiao Ming's exercise data, the system dynamically adjusts the training intensity to ensure that the training intensity remains within a reasonable range.

[0087]

[0088] Calculate the training intensity and ensure that the intensity of each training session does not exceed Xiao Ming's maximum athletic ability.

[0089] The training time is controlled at 20 minutes, and training is conducted 5 times a week. Through this interactive virtual environment training, Xiao Ming's athletic ability has been enhanced, and his sense of participation and training enthusiasm have also been improved.

[0090] 3. During the training process, the system conducts real-time data analysis and feedback based on Xiao Ming’s performance to ensure that his training effect is continuously optimized.

[0091] Step 3.1: The system uses the somatosensory sensor to collect Xiaoming's motion data in real time. The system calculates the error value and adjusts the training content. For example, if Xiaoming reacts slowly or makes a high error rate in a certain movement, the system will automatically reduce the difficulty of the movement and provide more intuitive movement prompts to help Xiaoming correct his mistakes.

[0092] Step 3.2: The system adjusts the difficulty and intensity of the training tasks based on Xiao Ming's real-time motion data. For example, if Xiao Ming successfully completes a difficult jump task, the system will appropriately increase the difficulty of subsequent tasks according to the formula α(t), promoting further improvement in his athletic ability.

[0093] 4. After two months of training, Xiao Ming's therapist and parents are eagerly awaiting the results. At this point, the system conducts a final evaluation.

[0094] Step 4.1: After the training session, the therapist reassessed Xiao Ming using the Peabody Developmental Motor Scale (PDMS-2), the Gesell Developmental Diagnostic Scale (GDS), the Berg Balance Scale (BBS), and the Child Adaptive Behavior Assessment Scale (CABS). The results showed that Xiao Ming's Gross Motor Quotient (GMQ) improved from 72 to 82, and his Fine Motor Quotient (FMQ) improved from 68 to 75. His Developmental Quotient (DQ) improved from 68 to 80, his balance ability improved from 26 to 34, and his Adaptive Behavior Quotient (CAQ) improved from 55 to 70. Overall, Xiao Ming made significant progress in motor skills, intelligence, balance, and adaptive behavior.

[0095] Step 4.2: Based on the final assessment results, the system generates a detailed training report. This report includes Xiao Ming's progress in various abilities and provides improvement suggestions for subsequent training. The report also includes training data analysis, such as the average error of weekly training sessions and changes in training intensity, to help parents and therapists understand Xiao Ming's recovery progress.

[0096] 5. All training data and evaluation results are stored in the system's cloud database, accessible to parents and rehabilitation trainers at any time via a mobile app or computer. Parents can view Xiao Ming's training progress in real time, monitor his training results remotely, and adjust the training content or difficulty as needed.

[0097] This example demonstrates the effectiveness of the system in real-world situations. By combining multisensory stimulation with virtual reality technology, the system provides Xiao Ming with multi-dimensional training, enhancing not only motor development but also intellectual development, balance, and adaptive behavior. All training processes are intelligently adjusted by the system, ensuring that the training content is both challenging and adaptable to the child's actual abilities.
