For example, an AI-based system could be used to analyze videos of babies during their first attempts to crawl or walk. AI algorithms can identify specific patterns of movement, such as the speed, amplitude, and symmetry of movements, and compare them to typical motor development milestones [43]. Based on this analysis, the system can provide feedback to parents or healthcare professionals on the child’s motor progress, indicating whether there are any delays or abnormalities that may require intervention [44]. Additionally, AI can be used to develop personalized intervention programs for children with motor difficulties. Based on the data collected about the child’s movement and data analysis algorithms, the system can identify specific areas of weakness or challenge and suggest activities and exercises tailored to the child’s individual needs [18]. This allows for a more targeted and effective approach to improving motor development and overcoming any obstacles the child may face.

In summary, the application of artificial intelligence in the field of child motor development can offer a range of benefits, from the early detection of anomalies to the development of personalized interventions. These systems have the potential to significantly improve the quality of childcare and ensure that all children reach their full motor potential.

4. Training

Apart from the abovementioned features, we envision significant problems in terms of the training required for technicians who use these technologies [45]. Technological evolution often outpaces the speed of adequate training, resulting in a knowledge gap between the development of tools and the ability of health professionals to use them effectively [46]. Healthcare technicians and professionals need ongoing training to keep up with innovations and maximize the potential of wearable technologies and artificial intelligence [16]. This knowledge gap can lead to the underutilization or misuse of devices, compromising the accuracy of the data collected and the effectiveness of interventions based on those data. Additionally, the complexity of AI systems and algorithms can be intimidating for those without specific technical training, making it difficult to correctly interpret the results and implement appropriate measures [47]. Insufficient training can also affect the confidence of health technicians and professionals in the use of these technologies, potentially limiting their adoption and integration into daily clinical practice. To address this issue, it is essential to develop accessible, continuing education programs that include both theory and practice [45]. Workshops, online courses, certifications, and collaboration with technology developers can help reduce this knowledge gap.

In addition, training must include ethical and privacy aspects, ensuring that professionals are prepared to deal with the sensitive data collected by these technologies [48]. Thus, continuous training is essential to ensure that wearable technologies and artificial intelligence are used effectively, safely, and ethically, maximizing their benefits for children’s motor development and overall health [49].

While wearable technologies and artificial intelligence offer numerous advantages in monitoring and analyzing motor development, they also have some limitations [52]. Firstly, the accuracy of the data collected can be affected by the quality of the sensors and the correct placement of the devices on the body, which can result in inaccurate or inconsistent measurements. In addition, interpreting the data requires sophisticated and well-trained algorithms, which may not always be accurate or adaptable to all individual variabilities. Another important limitation is accessibility and cost. High-tech devices can be expensive, which can limit access for low-income populations or in regions with fewer resources. Usability and acceptance are also challenges, as not all children or their parents can be comfortable with the continued use of wearable devices, especially if they are intrusive or uncomfortable.

On other hand, data privacy and security are critical concerns, as continuous monitoring generates a large amount of sensitive personal data that need to be protected from unauthorized access and potential breaches [53]. In addition, the integration of these devices with broader healthcare systems can be complex and may require adequate infrastructure and interoperability between different technologies and platforms. Finally, there is the issue of technological dependence. Over-reliance on wearable technologies can lead to a decrease in traditional clinical observation and human interaction, which are irreplaceable in the holistic assessment of motor development [54]. From our point of view, these limitations highlight the need for a careful balance between the use of advanced technologies and traditional approaches in monitoring and promoting child motor development.
