Barriers, facilitators and interventions for foot abduction brace adherence in the Ponseti management of idiopathic clubfoot in low- and middle-income countries: a scoping review
This scoping review identifies that foot abduction brace non-adherence in low- and middle-income countries is driven by a complex interplay of structural, economic, and psychological barriers, necessitating multi-component interventions that address environmental constraints alongside caregiver education and support to prevent clubfoot relapse.

The Big Picture: Fixing a Crooked Foot
Imagine a baby is born with a foot that is twisted inward and downward, like a shoe stuck in a deep rut. This is called clubfoot. The "gold standard" way to fix it is a method called Ponseti.
Think of the Ponseti method like a two-part journey:
- The Repair Phase: Doctors gently stretch and cast the foot (like straightening a bent wire) until it looks normal. This part usually works great.
- The Maintenance Phase: Once the foot is straight, the baby must wear a special Foot Abduction Brace (FAB). This is a bar with two little shoes that holds the foot in the correct position. The baby wears this full-time for a few months, then mostly at night and nap time for four to five years.
The Problem: Even though the foot is fixed, it often twists back (relapses) if the parents stop putting the brace on. In poorer countries (Low- and Middle-Income Countries, or LMICs), this stopping happens a lot.
What This Paper Did
The author, Kaweesi Calvin Nantalaga, didn't run a new experiment. Instead, they acted like a detective gathering clues. They looked at 10 different studies from countries like Uganda, India, Bangladesh, and Iraq to answer one question: Why do families in these countries stop using the brace, and what helps them keep going?
They used a framework called COM-B (Capability, Opportunity, Motivation) to sort the answers. Think of this as a three-legged stool; if one leg is missing, the family can't stay on the "adherence" stool.
The Three Legs of the Stool (Why Families Struggle)
1. Opportunity (The "Can We Do It?" Leg)
This is the biggest hurdle. It's not that parents don't want to do it; it's that the world makes it too hard.
- The Analogy: Imagine you have a prescription for medicine, but the pharmacy is 50 miles away, the bus fare costs your entire day's wages, and the medicine is often out of stock. You might want to get better, but the system blocks you.
- The Findings:
- Travel & Money: Getting to the clinic costs too much money and time.
- Missing Pieces: Sometimes the brace isn't available, or the baby didn't get a tiny procedure (tenotomy) that makes the foot flexible enough to brace easily.
- Broken Systems: The clinic follow-up system is weak. If you miss an appointment, no one calls to check on you.
2. Capability (The "Do We Know How?" Leg)
This is about understanding.
- The Analogy: Imagine you are told to wear a cast for a broken leg. If you don't understand why you need to wear it for 6 months, you might take it off as soon as the pain stops, thinking the leg is healed.
- The Findings:
- Many parents think that once the foot looks straight, the job is done. They don't realize the brace is needed for years to stop the muscle from pulling the foot back into the wrong shape.
- They aren't taught clearly how to put the brace on or what to do if the baby cries.
3. Motivation (The "Do We Want To?" Leg)
This is about feelings and emotional drive.
- The Analogy: Imagine trying to keep a toddler in a car seat. If the child screams and kicks every time you buckle them in, and you feel guilty or embarrassed, you might eventually just give up and let them sit without it.
- The Findings:
- The Baby's Distress: The brace is uncomfortable. Babies cry, kick, and try to pull it off. This wears down the parents' resolve.
- Guilt & Shame: Parents feel bad seeing their child cry or feel judged by others for the "weird" brace.
- Misunderstanding: Some families believe the clubfoot is caused by supernatural forces, so they stop medical treatment to try other things.
What Helps? (The Solutions Found)
The paper looked at what successful programs did to fix these three legs. They didn't just tell parents "try harder." They changed the environment.
- Fixing Opportunity: They brought clinics closer to villages, gave money for bus fare, and made sure braces were always in stock.
- Fixing Capability: They used "Teach-Back" methods (asking parents to show the doctor how to put the brace on to prove they understand) and gave clear instructions.
- Fixing Motivation: They used "peer support"—parents whose kids finished treatment successfully came back to encourage new parents. They also used digital reminders (text messages) to check in.
The Bottom Line
The paper concludes that stopping the brace isn't usually because parents are lazy or unwilling. It's because the system is too expensive, too far away, and too confusing.
- The Result: When families stop wearing the brace, the foot almost always twists back.
- The Solution: To fix this, we need a "multi-tool" approach. We can't just give a lecture; we have to fix the roads, pay for the bus, teach the parents clearly, and support their emotions.
One Final Note: The author admits that while we know what the problems are, we don't have many studies that rigorously test which specific solution works best. We have a map of the obstacles, but we need more experiments to build the best bridge across them.
