In brief
- The most widely cited evidence review in cerebral palsy care graded around 180 interventions using a traffic light system. Dynamic Movement Intervention does not appear in it.
- That is because DMI was established in 2021 and the review's literature search closed in 2019. DMI was not assessed and rejected. It was not assessed at all.
- Being absent from a review is not the same as being red-lighted in one. Parents researching DMI are frequently handed the harsher reading.
- Several approaches that DMI draws on — task-specific training, weight-bearing, goal-directed training, strength training — are green-lighted in that same review.
- What remains true is that no outcome study of DMI itself has been published yet. A randomized trial completed in June 2026 and its results are pending.

What the evidence reviews actually are
When a clinician says an intervention is or isn't "evidence-based" for cerebral palsy, they are usually referring to a body of systematic reviews led by Iona Novak and colleagues. The most recent, State of the Evidence Traffic Lights 2019, was published in Current Neurology and Neuroscience Reports in February 2020.
It reviewed the available evidence from 2012 to 2019, graded it using GRADE and an Evidence Alert Traffic Light System, and combined those findings with an earlier 2013 review. Interventions come out green, yellow, or red — worth doing, uncertain, or don't do it.
Why DMI is not in it
DMI was established in 2021. The review's literature search closed in 2019. There was nothing to assess.
This matters because of how the absence gets read. A parent who searches whether DMI is evidence-based will find these reviews, will not find DMI in them, and will reasonably conclude it was looked at and found wanting. It wasn't. It postdates the review entirely.
An intervention that was assessed and red-lighted has been tested and found not to work. An intervention that is absent has not been tested. Those are different situations and they call for different decisions.
What the reviews do say about DMI's building blocks
DMI is not a wholly novel idea. It evolved from Cuevas Medek Exercises, developed in the early 1970s, and it works by placing a child in positions that demand active postural responses against gravity, with support withdrawn progressively as control improves.
Several of the principles it draws on are green-lighted in the same review that omits DMI, including task-specific training, goal-directed training, weight-bearing, strength training, and treadmill training.
That is not evidence that DMI works. A combination of individually supported principles still has to be tested as a whole, and it hasn't been. But it does mean DMI is not operating outside mainstream ideas about how motor learning happens, which is a fair thing for a parent to know.
What is genuinely unresolved
Two things are true at the same time, and honest sources say both.
No outcome study of DMI has been published. A critical review in Pediatric Physical Therapy in January 2026 argued on that basis that DMI should not be presented to families as an established treatment, and DMI's co-founders published a response.
And a randomized controlled trial comparing DMI with the Bobath approach in children with spastic cerebral palsy completed in June 2026. Its results have not been published. When they are, they will settle far more than either of those papers.
What this means for your decision
If you have been told DMI isn't evidence-based, the accurate version is narrower than it sounds: DMI has not yet been studied in a published trial. It has not been studied and failed.
That is a reasonable basis for caution and a reasonable basis for trying it, depending on your child's situation, what conventional therapy has produced so far, and what you can afford. What it is not is a basis for anyone telling you the question is settled in either direction.
Ask any provider what they expect for your child, over what timeframe, and what would tell them to stop. That question is more useful than the evidence-base question, because it is answerable now.
