Physical Therapy for Torticollis and Plagiocephaly in Infants

Q: At what age should I start physical therapy for torticollis?

As early as possible. Research shows the best outcomes when PT begins before 3 months of age. If your pediatrician notices torticollis at a well-child visit, ask for a PT referral right away. Even starting at 4-6 months produces very good results for most babies.

Q: Will my baby need a helmet?

Not necessarily. Many cases of plagiocephaly resolve with consistent repositioning and PT alone. Helmets are generally recommended for moderate-to-severe cases that haven't improved after several months of conservative treatment, and they work best before 12 months of age. Your pediatrician or a craniofacial specialist can evaluate severity using standardized measurements.

Q: How long does it take to see improvement from PT?

Many families see meaningful improvement within 6-8 weeks of consistent PT and home stretching. Full resolution for mild-to-moderate torticollis often takes 2-4 months. Improvement in plagiocephaly through repositioning is slower — expect 3-6 months of consistent effort to see measurable head shape changes.

Q: Can I do stretches at home on my own?

Yes — home stretches are a key part of treatment. But you should learn them directly from a physical therapist first, not from a video or general guide. Stretching an infant's neck incorrectly can cause discomfort or injury. Once a PT teaches you the correct technique and confirms your baby is tolerating it well, home exercises become very effective.

Q: Does plagiocephaly affect brain development?

Positional plagiocephaly is a skull shape issue, not a brain issue. The brain is not compressed and development is not directly affected by the flat spot itself. However, untreated torticollis can limit a baby's movement exploration and affect motor development over time, which is one reason early PT matters beyond cosmetics.

Q: Will insurance cover PT and helmet therapy?

PT for torticollis is typically covered by insurance with a physician referral. Helmet coverage varies widely — some insurers cover it, others classify it as cosmetic. Ask your insurance provider before beginning helmet treatment, and ask the orthotist's office to help with the prior authorization process. Some families appeal successfully when the functional and developmental rationale is documented.

You noticed your baby always turns their head to one side. Or maybe the back of their head looks a little flat. You asked the pediatrician, and they said words like "torticollis" or "plagiocephaly." Now you're wondering what comes next.

This article explains both conditions clearly. It covers how physical therapy helps, what stretching and repositioning look like, and how to think through the helmet question. It's part of our Pediatric Physical Therapy: A Complete Parent's Guide — a full resource for families navigating PT for infants and children.

You are not alone. These are two of the most common reasons infants are referred to physical therapy. And when caught early, outcomes are very good.

Key Takeaways

Torticollis means a baby's neck muscles are tight on one side, causing the head to tilt or rotate.
Plagiocephaly (flat-head syndrome) often develops alongside torticollis, because babies favor one position.
Physical therapy is the first-line treatment for both. It focuses on stretching, strengthening, and repositioning.
Helmets (cranial orthoses) are sometimes recommended for moderate-to-severe plagiocephaly, but timing matters — they work best before 12 months.
Starting PT early — ideally before 6 months — leads to faster, more complete improvement.

What Are Torticollis and Plagiocephaly?

Torticollis literally means "twisted neck." In infants, it usually happens when one of the muscles running down the side of the neck — the sternocleidomastoid (SCM) — is shorter or tighter than the other. Babies with torticollis tend to tilt their head toward one shoulder and rotate their chin toward the opposite shoulder.

There are two main types:

Muscular torticollis: the most common type, caused by tight neck muscles. Sometimes a small lump (called a fibrotic mass) is felt in the muscle.
Positional torticollis: caused by positioning in the womb or after birth, without a structural muscle change.

Plagiocephaly means an asymmetric or flat head shape. When a baby's skull is still soft and they spend too much time with their head in one position, the skull can flatten on that side. This is called positional plagiocephaly.

Because torticollis causes babies to favor one head position, the two conditions frequently go together. A baby who always looks right will develop a flat spot on the right side of their head.

The American Academy of Pediatrics (AAP) has addressed positional plagiocephaly directly, noting that while the "Back to Sleep" safe-sleep guidance dramatically reduced SIDS deaths, it also increased rates of flat-head syndrome — making supervised tummy time and repositioning strategies more important than ever (AAP Clinical Practice Guideline, aap.org).

Signs to Watch For in Your Baby

Many parents first notice something is off when their baby is a few weeks old. Here's what to look for:

Signs of torticollis:

Head consistently tilts to one side
Baby has trouble turning to look in one direction
Breastfeeding is much easier on one side than the other
You feel a firm lump or tightness in one side of the neck

Signs of plagiocephaly:

Flat spot on one side of the back of the head
One ear appears pushed forward compared to the other
The forehead or cheeks look uneven when viewed from above
The face looks slightly asymmetrical

If you notice any of these, mention them to your pediatrician. Early referral to a pediatric physical therapist makes a real difference.

How Physical Therapy Treats Torticollis

A pediatric physical therapist evaluates your baby's neck range of motion, muscle tone, and overall movement patterns. From there, they build a plan tailored to your baby's specific needs.

Treatment for torticollis typically focuses on three areas:

1. Passive Stretching

The therapist gently moves your baby's head through its full range of motion. The goal is to lengthen the tight SCM muscle and restore symmetrical neck movement. You'll be taught to do these stretches at home — usually several times a day.

2. Active Strengthening

As the neck loosens, babies need to build strength on the weaker side. Therapists use toys, sounds, and positioning to encourage babies to turn and look the other way. Tummy time plays a big role here.

3. Handling and Positioning Education

Parents are often the best "therapists" because they're with their baby all day. A physical therapist will show you how to hold, carry, feed, and position your baby to gently encourage the affected muscles and reduce the habit of favoring one side.

The American Physical Therapy Association (APTA) recognizes pediatric physical therapists as trained specialists in musculoskeletal and neurodevelopmental conditions in children (APTA, apta.org). Early PT intervention for torticollis is supported by strong evidence — a systematic review published in the Journal of Pediatric Physical Therapy found resolution rates above 90% when PT began before 3 months of age.

Repositioning Strategies You Can Use at Home

Between PT visits, repositioning is one of the most powerful tools you have. It doesn't require equipment. It just requires consistency.

Tummy time is the foundation. Supervised tummy time helps flatten rates drop and builds the neck and shoulder strength babies need. Aim for small, frequent sessions — starting with 2-3 minutes several times a day, building to 30 minutes total by 3-4 months.

Change your baby's orientation in the crib. Alternate which end of the crib your baby's head is at, so they turn toward activity and light from different directions.

Carry and hold with intention. If your baby tilts right, position them during feeding and carrying so they're gently encouraged to look left. A physical therapist can show you specific holds.

Limit time in infant seats, bouncers, and car seats outside of necessary use. These devices keep babies in one position and can worsen flat spots. "Container baby syndrome" is a real concern — prolonged time in any device limits the free movement babies need.

Use a rolled towel or wedge (under supervision) to encourage your baby to maintain a more neutral head position during awake time.

These strategies also tie directly to Gross Motor Delays in Children: A Parent's Guide, because tummy time and free movement are essential to developing the muscle patterns babies need to roll, sit, and eventually walk.

When Is a Helmet Recommended?

This is the question parents ask most. The answer: it depends on severity, age, and how repositioning and PT are working.

Helmets — formally called cranial orthoses or cranial remolding orthoses — work by creating gentle, consistent pressure that redirects skull growth into a more symmetrical shape. They are custom-fitted and worn 23 hours a day.

Helmet therapy is most effective between 4 and 12 months, when the skull is growing fastest and is most responsive to reshaping. After 12-18 months, skull bones begin to fuse and helmets become much less effective.

The AAP's official position states that helmets should not be recommended routinely for mild cases, but that moderate-to-severe plagiocephaly that has not improved with repositioning and PT by 4-6 months of age may warrant referral to a specialist for helmet evaluation (AAP, aap.org).

Questions to ask when discussing a helmet:

How severe is the asymmetry, measured by a cephalic index or diagonal difference?
How long have repositioning and PT been consistently practiced?
What is my baby's current age?
What does the craniofacial specialist or certified orthotist recommend?

Not every baby with a flat spot needs a helmet. Many cases resolve fully with PT and repositioning alone. But for families where a helmet is recommended, early action matters.

What to Expect During PT Sessions

Most pediatric PT appointments for torticollis and plagiocephaly are 45-60 minutes. The first visit is an evaluation — the therapist will measure your baby's neck range of motion, assess head shape, and observe how your baby moves during tummy time and supported sitting.

From there, visits often happen weekly or every two weeks. Progress can be fast. Many infants with mild-to-moderate torticollis resolve within 2-4 months of consistent PT and home stretching.

Parents are active participants. You won't sit in the waiting room. You'll be in the room, learning techniques and asking questions.

PT for torticollis also connects to broader developmental monitoring. If a therapist notices other movement concerns — like delays in rolling or asymmetrical muscle tone — they may flag those for further evaluation. This overlap is why we also recommend reviewing our article on Physical Therapy for Children with Cerebral Palsy, which covers how early movement differences can signal larger neurological patterns.

Some babies who show feeding asymmetry alongside torticollis may also benefit from a speech-language pathology evaluation. You can read more in the Pediatric Speech Therapy Guide. Similarly, if sensory sensitivities or fine motor concerns come up, the Pediatric Occupational Therapy Guide is a helpful companion resource.
