Determinants of default from pediatric neuro-rehabilitation services in Cerebral Palsy: A matched case-control study

For a child born with cerebral palsy, the journey toward movement and independence is rarely a straight line. It is a lifelong path that requires consistent, specialized physical therapy, speech training, and occupational support to prevent muscles from tightening and joints from locking. In the medical world, this continuous care is known as neurorehabilitation. Without it, the secondary complications of the condition can become as disabling as the condition itself. Yet, in many parts of the world, particularly in lower-income nations, a silent crisis undermines this care: families simply stop showing up. When a child misses appointments for a year or more, the progress made in the clinic begins to unravel at home. Understanding why these families disappear from the system is not just a matter of tracking attendance; it is about uncovering the invisible walls that separate a vulnerable child from the help they need to thrive.

Researchers in Sri Lanka recently set out to map these invisible walls. They focused their investigation on the Lady Ridgeway Hospital for Children in Colombo, the country's largest pediatric facility. The team wanted to know why some families managed to keep their children in the rehabilitation program while others dropped out. To find the answer, they did not simply ask people why they left; they built a careful comparison. They gathered a group of seventy-two children who had stopped coming to therapy and matched them with one hundred and forty-four children who had stayed on track. By looking at the two groups side by side, the researchers could separate the common struggles of poverty from the specific factors that actually caused a family to give up.

The study revealed that the decision to stop treatment was not driven by a single overwhelming problem, but by a crushing combination of five specific pressures. The first and most powerful factor was the severity of the child's physical disability. Children who could not walk or stand on their own were far more likely to be lost to the system than those who could move with some independence. The second factor was how the family traveled. Those who relied on public buses and trains to get to the hospital were much more likely to default than those who could hire a private vehicle or drive their own car. The third pressure was economic, but not in the way one might expect. It was not the cost of the bus ticket that broke the family; it was the cost of the day's wages. Many parents worked daily labor jobs where missing a single day meant losing their entire income. Taking a child to a mid-week appointment meant forfeiting that day's earnings, a loss that compounded with the travel costs to make the visit unaffordable.

The fourth factor was the presence of uncontrolled seizures. Children whose epilepsy was not well-managed were significantly more likely to stop coming for therapy, likely because the immediate chaos of managing a seizure took precedence over long-term rehabilitation goals. The fifth factor was the absence of government support. Families who did not receive a state disability allowance were much more likely to drop out than those who did, suggesting that even a small financial safety net can make the difference between staying in care and leaving it.

Interestingly, the study ruled out some assumptions that often guide policy. The distance to the hospital did not matter as much as people thought. Families living far away were not more likely to quit than those living closer, provided they had a way to travel. The direct cost of the fare was also not the deciding factor. The real barrier was the physical exhaustion of carrying a heavy, non-ambulatory child onto a crowded bus, combined with the financial penalty of losing a day's income. The researchers also found that the type of transport mattered more than the distance; the struggle of navigating public transit with a child who cannot walk was a unique and overwhelming hurdle.

Beyond the logistics, the study uncovered deep psychological and social divides. Families who dropped out were far more likely to lack information about why rehabilitation was important, to rely on traditional or alternative medicines instead of hospital care, and to feel afraid of being scolded by hospital staff. They also reported feeling isolated, with many mothers lacking support from their spouses. In contrast, families who stayed in the program were often those where the child was the youngest in the family, perhaps because the parents had more energy or fewer competing demands from older siblings.

The findings paint a clear picture of a system that works for some but fails others not because of a lack of medical expertise, but because of a lack of structural support. The children who fall through the cracks are not those who do not need help, but those whose needs are too heavy for their families to carry alone. The researchers suggest that fixing this requires more than just telling families to come back. It requires changing the system itself: bringing therapy closer to where people live, providing financial help to replace lost wages, and training staff to be supportive rather than intimidating. Until these changes happen, the most vulnerable children with cerebral palsy will remain the ones who disappear from the clinic, leaving their potential for movement and independence behind.
