Feasibility of a parent-led Premalocom crawling training protocol for preterm infants with high risk of motor deficits
This study demonstrates that a parent-led Premalocom crawling training protocol, delivered at home with professional supervision for high-risk preterm infants, is feasible and effectively stimulates active locomotion, although parental adherence is lower than professional-led delivery and correlates with socioeconomic status.

For many babies born far too early, the world begins in a hospital room filled with machines and soft lights, a place where their tiny bodies are protected while they grow. But once they leave that safety and return home, the intense, specialized care they received often stops. This gap is a concern for doctors because the first few months of life are a critical window when the brain and muscles are learning to work together. If a baby misses out on practice during this time, especially if they were born very prematurely or had brain injuries, they may struggle later with basic movements like crawling or walking. Scientists have long known that movement is not just about muscles; it is a conversation between the body and the brain that shapes how a child learns to think and interact with the world. The challenge has been finding a way to keep this practice going at home, where parents are often overwhelmed and unsure how to help, without needing a specialist to visit every single day.
A team of researchers in France set out to solve this problem by testing a new way to help high-risk babies learn to move. They focused on a specific type of training called Premalocom, which encourages babies to crawl on their bellies using a small, wheeled board. In a previous study, this training worked well when done by therapists, but the researchers wanted to know if parents could do it themselves. They recruited twenty-two very premature infants, some of whom had significant brain injuries, and asked their parents to guide them through daily crawling sessions at home for eight weeks. The parents were not left alone; they received regular visits from professionals who taught them the technique and checked on their progress. The goal was to see if this parent-led approach was possible and if the babies could actually move effectively on their own.
The results showed that while it was harder for parents to stick to the schedule than it was for the therapists, the training itself was a success. The families completed about 70 percent of the planned sessions, a number that dropped slightly when parents were the ones leading the practice. The researchers found that families with lower incomes and fewer resources found it more difficult to keep up with the daily routine, likely due to the many competing demands on their time and energy. However, for the sessions that did happen, the parents were remarkably good at their job. In fact, when parents led the training, the babies moved faster and covered more distance than when the same babies were trained by the professionals. The babies were able to push themselves forward on the wheeled board, traveling an average of over five meters every day they practiced. This was surprising because the researchers had expected the babies to move less when their parents were in charge, assuming that parents might be less skilled or that the babies would be more tired.
The study also looked at how the babies felt during the training. The researchers noticed that the babies who were more alert and active, even if they cried a bit, tended to move further and faster. This suggests that the baby's state of mind plays a big role in how well they use their muscles. Interestingly, the babies in this new study, who were at higher risk for motor problems than the babies in the earlier study, moved just as well as the previous group. This means that even the most fragile infants can benefit from this kind of early movement practice. The parents reported that the training was stressful at first but became easier and more rewarding as time went on. They felt that the sessions helped them connect with their babies and that the babies were happy to participate. The researchers concluded that having parents lead the training is a feasible and powerful way to support these children, provided they have regular support from professionals to keep them motivated and on track. The study did not yet measure how this training affected the children's long-term development, as that part of the research is still ongoing, but the immediate results suggest that parents can be the most effective coaches for their own children's early movement.
