Intensive blocks or weekly sessions: which helps a child more?
Neither is better in general, and the honest answer depends on the goal. Blocks suit a specific, trainable target within a few weeks. Weekly therapy suits goals that need daily life to change around them. What predicts progress in both is practice of the real task, not the format.
What does the evidence actually support?
The systematic reviews of paediatric neurological rehabilitation converge on a pattern rather than a schedule. Interventions that work are goal-directed, practised by the child rather than done to the child, delivered in the environment where the skill is needed, and repeated enough times to change a habit.
Passive approaches — stretching alone, handling without a task, equipment without practice — consistently show less. That finding matters more than the block-versus-weekly question, because a poorly designed intensive block is still a poorly designed programme.
When does an intensive block make sense?
When there is a specific, measurable target that a few weeks of concentrated practice can move: standing from the floor, walking a given distance, using an affected hand in a two-handed task, tolerating a new orthosis. Blocks also suit families who travel, because the programme and the journey have the same shape.
They suit less well a child who is unwell, who has just had surgery with movement restrictions, or whose main barrier is at home rather than in the clinic.
What happens after the block ends?
This is where most intensive programmes are won or lost. Gains made in a block fade unless the home programme is genuinely usable — short, specific, built into an existing routine, and taught to whoever is actually with the child in the afternoon.
Ask any provider what the block ends with: a written home programme, the measurements from the first and last day, and a named review date. A block that ends with a discharge handshake was sold rather than planned.
How do we know whether it worked?
By measuring the same things before and after with instruments that were designed for children, and by agreeing the goals in the family's words before the block begins. Goal attainment scaling exists precisely so that "can fasten his own coat" becomes a scoreable target.
We report those figures whether or not they moved. A block that produced no measurable change tells you something useful about the next one, and hiding that costs the family more than it costs us.
Frequently asked questions
How intensive is too intensive for a child?
The limit is the child's tolerance rather than a number of hours. Refusal, exhaustion and lost sleep are signs the dose is wrong, and a good programme reduces it rather than pushing through.
Can school be part of the programme?
It should be. Skills practised only in a therapy room transfer poorly, and the most effective paediatric programmes put the target task into the settings where the child actually needs it.
Is a suit or a robot necessary?
No. They are tools for delivering more correct repetitions, and they help where that is the limiting factor. They do not replace the goal-directed practice that the evidence actually supports.

Paediatric Paediatric What do the GMFCS levels mean in cerebral palsy?
The Gross Motor Function Classification System (GMFCS) describes how children with cerebral palsy usually move, in five levels. Level I means walking without limitations, level II walking with limitations, level III walking with a hand-held aid, level IV limited self-mobility often using powered mobility, and level V being transported in a wheelchair.Read morePaediatric When is toe walking in children a concern?
Toe walking is common in young children, and most outgrow it. In a Swedish study, a small minority of children had walked on their toes, and most of these had stopped by later childhood without any treatment. It needs assessment if a child cannot stand flat, walks only on one side, has stiffness or developmental concerns, or loses skills.Read more
