In this blog post we are going to go over how to check for infant neck strength, in infants 3 months+, as well as the best markers for infants < 3 months for neck strength. We are also going to go over torticollis and plagiocephaly (head shape/head flatness) because these both can influence neck strength in infants significantly and all parents need to screen their infants for Torticollis and Plagiocephaly from day one.

Torticollis: A Quick Overview

First things first, let's talk about torticollis. This condition involves a tilt to one side and a rotation to the other, often due to tightness in the sternocleidomastoid muscle. But it's not just a neck issue; it can involve the whole body – from the arms and shoulders down to the pelvis.

Right vs. Left Torticollis: The side of the torticollis is named after the side of the TILT. The sternocleidomastoid muscle tilts to the same side as the muscle, but rotates to the opposite side, which makes it kind of confusing to parents.

Right Torticollis: If your baby has a tilt to the right and rotates more easily to the left, it's the right sternocleidomastoid that's tight.

Left Torticollis: If your baby has a tilt to the left and rotates more easily to the right, it's the left sternocleidomastoid that's tight.

Why Early Intervention Matters

The earlier we catch and address any signs of torticollis or neck weakness, the better. Ideally, babies should be seen by a pediatric physical therapist before they turn one month old. Truthfully though, we are a LONG WAY OFF from this being the norm in the United States (hopefully it’s more common in other countries!).

Most of the time at one month old, parents are barely able to get in to the pediatrician, let alone in to see a Pediatric Physical Therapist or know that this is something that could be beneficial for them.

Luckily, a lot of Pediatric Physical Therapists like myself are sick of parents getting frustrated that they didn’t know they could’ve done something earlier and we are here, hanging out on the internet, trying to get our knowledge in YOUR hands, if you need it.

Early intervention can significantly reduce the amount of therapy needed compared to starting after one month of age.

The national data for Pediatric Physical Therapy results with Torticollis is as follows:

0-1 month: 1.5 months average time of treatment

1-3 months: 5.9 month average time of treatment

3-6 months: 7.9 month average time of treatment

6-12 months: 8.9 month average time of treatment

The good news, though, is that Pediatric Physical Therapists who specialize in infants can often see quicker results in infants who are within the 0-5 month range closer to 3 months average length of weekly Pediatric Physical Therapy with sometimes needed but much less frequent visits up to six months, especially if a child is also receiving craniosacral therapy, chiropractic care, or infant massage.

The take home message is this: the earlier the better, not just because it doesn’t take as long, but also because the baby’s experience is so much easier when they are younger. Tightness in the body does not feel good and older babies can be cranky trying to help them resolve Torticollis and the movement struggles that are caused by unresolved Torticollis.

Plagiocephaly: Linked to Torticollis

Plagiocephaly, or flat head syndrome, often goes hand-in-hand with torticollis. A baby with a rotation preference might develop flatness on one side of their head (the side of the rotation preference), emphasizing the importance of early and proactive physical therapy.

This both make the Torticollis AND the Plagiocephaly worse. They’re like the worst kind of frenemies of new parents.

However, Plagiocephaly can also occur in utero, so monitoring head shape from birth is vitally important, especially because treating head shape without a helmet is only effective if the baby is seen by 3 months (some change possible 4-5 months but much less time to complete program, which results in decreased results and often a referral for a head shape scan/helmet after 5 months).

Testing Head and Neck Strength

Now, let's get into the nitty-gritty – how you can test your baby's head and neck strength at home. This simple check can help you spot any imbalances and take action. I recommend only doing this after the age of 3 months.

Prior to the age of three months, the best test of neck strength is whether a baby can tolerate tummy time and lift their head off the ground to 90 degrees and push through their elbows to lift their chest.

Age-Appropriate Expectations:

At 3 months: babies should keep their head horizontal

3 to 4 months: they should lift it slightly above horizontal

4 to 6 months and beyond: they should lift it significantly above horizontal, increasing in height as they age.

How to Test Neck Strength:

Start facing a mirror or set up your camera (I like the front facing view so you can see if you’re in the frame!).

Right Side Test: Place your right arm through your baby's legs, fingers on their abdomen. Your left arm goes between their bottom arm and chest, supporting them horizontally. Check how far the baby can lift their right ear towards their shoulder, holding for 5 seconds.

Left Side Test: Switch arms for testing the left side. Place your left arm through your baby's legs, fingers on their abdomen. Your right arm goes between their bottom arm and chest, supporting them horizontally. Check how far your baby can lift their left ear towards their shoulder against gravity.

Note if there is any difference side to side, if not, and your baby is consistent with the age recommendations, then your baby likely has equal strength side to side, if there is no rotation preference and no head tilt you are good to go!

If there is a difference side to side, your baby has a head tilt, rotation preference, or flatness in the back of their head a consultation with a Pediatric Physical Therapy is recommended.

Strengthening Exercises

If you find your baby struggles with maintaining head strength in the horizontal position, start in a more vertical position where gravity is less of an enemy. Gradually increase the challenge by tilting them more horizontally as they build strength. This gentle progression helps them develop neck muscle strength comfortably and effectively.

Recommendations for How Long

Start with 5 seconds, then increase to 15-30 seconds at a time for a total of 1-2 minutes split between sides. Always do both sides to make sure that neck strength stays equal.

Resources for Further Help

If you're eager for more detailed guidance or if you've noticed any concerns with your baby's neck strength or symmetry, my latest book, "Tummy Time and Learning to Roll," is a treasure trove of information.

It covers everything from the basics of torticollis and plagiocephaly to comprehensive exercises and strategies for ensuring your baby's development is on the right track.

When Should Babies Receive Pediatric Physical Therapy?

Parents can call and schedule with a Pediatric Physical Therapist at any time, for any concern in all fifty states without a referral from their Pediatrician.

Pediatric Physical Therapy is medically indicated in all babies who are not rolling in all four directions by six months (back to belly over their right arm AND left arm + belly to back over their right arm AND left arm).

Pediatric Physical Therapy is medically indicated if you notice a flat spot on the back of an infants head (possible plagiocephaly), a tilt of their head consistently to one side (ear to shoulder - possible torticollis), or a rotation preference of their neck (consistently look only to the right or left - possible torticollis).

Many Pediatric Physical Therapists including Dr. Baker, can successfully treat flat spots (Plagiocephaly) without a helmet with a combination of therapy and positioning strategies if seen prior to 4 months (0-3 months is ideal). Dr. Baker uses the Baby Begin Method of repositioning.

Flat spots can be due to in-utero positioning, rotational preference (right sided flatness most common) and babies are at an increased risk for flatness if they are male, were breech, multiple birth, premature, have difficulty with tummy time, or are in containers > 2 hr/day.
