DMI Therapy for Premature Babies and NICU Graduates
If your baby was born early, you have probably been told to "wait and see" more than once. You can do more than wait. You can measure your baby against the right age, ask for the early checks that spot cerebral palsy before 6 months, start free early intervention, and decide whether DMI therapy belongs in the plan.
This page covers corrected age, early detection, why DMI is used with premature babies, safety questions for NICU graduates, and where to start in Idaho.
What is corrected age, and why does it matter?
Corrected age is your baby's age counted from their due date instead of their birth date. To work it out, take your baby's age in weeks and subtract the number of weeks they were born early.
The American Academy of Pediatrics gives this example: a baby born at 32 weeks was 8 weeks early. At 4 months old, her corrected age is 2 months, so she should be compared with a 2-month-old born at term. The AAP says to use corrected age for the first 2 years.
Ask anyone who says your baby is behind whether they are using corrected or chronological age. The answer can change the whole conversation.
Is prematurity a diagnosis?
No. Prematurity is a risk factor. Idaho's Infant Toddler Program names prematurity as a condition that may result in a developmental delay, which is why premature babies can qualify for early intervention. It does not mean your baby will have one.
DMI lists children with risk factors for delays, such as those born prematurely, among the children who can benefit from DMI, because of the neuroplastic changes it aims to stimulate in the developing brain.
Can cerebral palsy be detected before 6 months?
Yes. Cerebral palsy has traditionally been diagnosed between 12 and 24 months of age. A 2017 international guideline in JAMA Pediatrics found it can now be diagnosed, or a high risk detected, before 6 months corrected age, using a combination of standardized tools. Before 5 months corrected age, the guideline names three as the most predictive:
Sensitivity is the share of babies who later develop cerebral palsy that a test catches. The tools work best together: the AACPDM care pathway says the General Movements Assessment plus an MRI predicts cerebral palsy more than 95% of the time before 5 months corrected age, and the HINE plus an MRI 90% of the time after that.
Why is DMI used with premature babies?
DMI works on automatic postural responses, the unplanned adjustments that keep the body upright against gravity. DMI says its exercises improve gross motor skills in children from birth, and Ascend Pediatric Therapy in Coeur d'Alene says DMI can start as early as 3 months of age.
The reasoning behind starting early is about neuroplasticity. DMI's clinical commentary puts it this way:
What does the research say about DMI for premature babies?
No study has tested DMI in premature babies yet. The published evidence so far is one 2026 case report, about a girl with Apert syndrome whose GMFM-88 score rose from 29.00% to 68.68% over eight months of DMI, starting at about 16 months of age.
Two randomized trials of DMI are registered, both in children with spastic cerebral palsy aged 2 to 7. Neither has posted results, and neither studies infants. DMI says its practitioners see benefits in the children they treat. Those reports are worth hearing, but they are not study results.

DMI also says any child at risk for osteopenia (weak bones) must be treated with extreme precaution, using support close to the body and very controlled movements. That matters for preemies: metabolic bone disease of prematurity means a premature baby's skeleton did not get enough calcium and phosphate, and in severe cases it is linked to rickets and fractures.
DMI applies the same extreme precaution to children with extreme low tone, and to children starting DMI or an intensive for the first time.
What to tell the therapist before the first session
Share your baby's full NICU history with the DMI therapist and your baby's doctor, especially:
- Any bone health concerns, including metabolic bone disease of prematurity or a past fracture.
- Breathing or lung problems, such as bronchopulmonary dysplasia or going home on oxygen.
- Heart conditions, repaired or not.
- Reflux or feeding issues that affect positioning, especially after feeds.
- A shunt, any other surgery, or seizures.
Then ask the therapist directly how they would adapt handling for a baby with that history.
How do I get my baby evaluated for free therapy in Idaho?
Contact the Idaho Infant Toddler Program. It is Idaho's early intervention program for children from birth to 3 with a developmental delay or a condition that may lead to one, and it names prematurity as one of those conditions. Services are provided at no cost to families, and you can apply on your own, without a doctor's referral.
The program supports physical, cognitive, and social-emotional development, not motor skills alone. DMI is a private service you can add alongside early intervention, not a replacement for it.
What should I ask a DMI provider about my baby?
- Which DMI level have you completed? Only therapists who have completed Level C may offer an official DMI Therapy Intensive.
- How much experience do you have with infants, and with premature babies in particular?
- Do you use corrected age when you talk about milestones?
- How will you adapt sessions for my baby's medical history?
- What would you expect to see, over what timeframe, and what would tell us it isn't working?
Where can I find DMI therapy for a premature baby in Idaho?

Common questions about DMI and premature babies
What is corrected age?
Corrected age is your baby's age counted from their due date. Subtract the number of weeks your baby was born early from their age in weeks. The AAP says to use corrected age for the first 2 years.
Can cerebral palsy be detected in premature babies before 6 months?
Yes. A 2017 guideline in JAMA Pediatrics found cerebral palsy can be diagnosed, or a high risk detected, before 6 months corrected age, using tools such as the General Movements Assessment, the HINE, and MRI.
Can premature babies do DMI therapy?
Yes. DMI lists babies born prematurely among the children with risk factors who can benefit, and says its exercises work on gross motor skills from birth. No study has tested DMI in premature babies yet.
Is DMI safe for NICU graduates?
DMI cannot be used with brittle bone conditions such as osteogenesis imperfecta, and DMI says children at risk for osteopenia, including metabolic bone disease of prematurity, need extreme precaution. Share your baby's full NICU history with the therapist and your baby's doctor first.
Is early intervention free in Idaho?
Yes. The Idaho Infant Toddler Program serves children from birth to 3, names prematurity as a qualifying condition, provides services at no cost to families, and accepts applications from parents without a doctor's referral.
