1) Assessment
The Primitive Reflex Assessment
This video will take you through the Retained Primitive Reflex exam so that you and a partner can assess whether any are still present. Written descriptions of each test along with the video time stamp can be found below.

Standing
Testing the Tonic Labyrinthine (0:25)
While standing, you should close your eyes and put your feet together. Your tester should stand to the side and make sure that they won’t let you fall. Be sure to keep your eyes closed the whole time
Instructions for tester: With their eyes closed and feet together, bend their head all the way back into full extension, then let go and tell them to try to stand still. Encourage them to stay in this position for at least five seconds. If the reflex is still retained, they will sway and their knees may buckle a bit.
Now, move the head back to neutral and then push it forward into full flexion (down, chin to chest). Again, step back and look for the same swaying or falling forward. Repeat three times. If the reflex is retained, the sway will become more and more pronounced and they may even fall backward or forward, so stay close to prevent them from falling. The bigger the sway, the more retained the reflex.
Testing the Asymmetric Tonic Neck Reflex - standing (2:20)
Immediately after testing the tonic labyrinthine reflex, stay in the same position with your eyes closed and feet together. Raise both arms straight in front of them.
For tester: Tell your subject you are going to turn their head to the right and left, but they must keep their arms straight out and their feet together and pointing straight ahead.
Standing behind them, place your hands on either side of the head and hold it firmly, then turn the head all the way to the right. As you do this, step slightly to the left of the subject. Turn the head to the end range and then slightly further, holding it in that position for five seconds. If the reflex is retained, the arms will not stay straight ahead; they will rotate and drift to the side of the head turn. Keep the head turned until the arm movement stops, then bring it back to a neutral position and the arms will snap back if the reflex is retained. Repeat to the left. Complete three times in each direction and grade the reflex on the last repetition. A slight movement is a 1, while the arms turning all the way with the head is a 4.
Testing the Moro (standing) (4:00)
For the tester: Once you complete the first two tests in the standing position, ask the patient to put their hands to the side and stand still, then clap loudly with your hands right behind their head three times. If the reflex is retained, they will jump each time and it may become more pronounced on the third time. Their heart rate may also jump, and they may become flushed.
Tabletop - On all fours
Testing for the Spinal Galant reflex (4:45)
You can test the spinal Galant reflex from almost any position, but the most common position is the tabletop position, on your hands and knees as with the ATNR and STNR.
Take the hard side of a paintbrush, and, starting along the spine about one inch to the side and below the level of the scapula, stroke down with a deep, firm, quick stroke all the way to the base of the lower back. Alternate from side to side and repeat a minimum of three times on each side. If the reflex is there, you will flex their back toward the side of stimulus. Start toward the middle of the spine as described and then, with each stroke, go a little more lateral toward the side of the child. The biggest response usually comes from the most lateral position.
This is what the spinal galant reflex looks like on a newborn. The head and hips move towards the side of stroking. This reflex should be integrated by 9 months of age.
Testing the Asymmetric Tonic Neck reflex (ATNR) - tabletop (6:07)
If you can get onto your hands and knees, test from this position. Your shoulders should be fully over your arms and hands, with hands flat and pointing forward. If the hands veer to the side, it is a sign of ATNR or symmetric tonic neck reflex.
Your tester should stand or kneel facing your head, put your hands on either side of your head, firmly cupping over the ears, maintaining a firm, stable grip.
Turn the head to the end of the range of motion and then slightly more. Observe if the elbow on the side of head turn extends slightly, and if the opposite elbow bends or significantly shakes. If the reflex is fully retained, the elbow will bend fully and that side of the body will collapse, so make sure your partner holds the head still and keeps you from falling over through a slight upward pressure. Turn the head back to the center and repeat on the opposite side.
Note how much the elbow bends and if it is more present on one side. Remember: no reflex should ever be asymmetric. Most commonly, the side the head is turned to when the opposite elbow bends, is the side of a more severe hemispheric developmental delay. For example, if we turn the head to the right and the left elbow bends more, it denotes a right hemisphere delay.
Complete three times on both sides and grade the severity level. If you are severely “double-jointed” and the elbows hyperextend when they are on their hands and knees, unlock your elbows by flexing them slightly before your partner turns your head.
Testing for the Symmetric Tonic Neck reflex (7:10)
Instructions for the Tester: Immediately after testing the ATNR, keep hold of the head but switch the position of your hands. If you are right-handed, instead of standing or kneeling in front of the patient, move slightly to the right side of their head. Place two or three fingers on your left hand under their chin and the right hand on the back of the top of the head, almost like palming a ball. Don’t place your full hand under the chin because when you flex the head, the hand may block the full flexion and it may compress the neck, which can be very uncomfortable.
Flex the head all the way down. Make sure to push the head down, not backwards. If the reflex is present, the elbows will both bend and the legs may extend a bit, rocking the individual forward. With your bottom hand, apply a slight upward pressure to prevent them from completely collapsing, so their head may touch the ground or floor.
The whole head and body may collapse as the elbows reflexively bend, so make sure to maintain control of and hold up the head. Push up with your bottom hand to a neutral position and extend the head all the way back as far as it can go. If the reflex is present, both arms will extend and both legs will flex, making the patient sit back on their heels a bit. Repeat three times and grade the severity on the third try.
Lying on your back (supine)
Testing for the Babinski reflex (9:00)
With the hard side of a paintbrush, stroke up the outside of the foot toward the ball of the foot, stopping just under the ball of the foot. Maintain deep, firm pressure and a quick stroking motion from the base of the hill, aiming at an area roughly between the fourth and fifth toes. If the reflex is still present, the foot and big toe will extend back towards your face, and the other toes will also extend and may flare apart. If the reflex is gone, it is replaced by what is known as the plantar reflex and the toes will curl down with the same stroking movement.
Stroke with firm pressure three times on each foot. Sometimes, the toes may initially go down but reverse direction with the second or third stroke. This means the reflex is still present but partially integrated, which is why you need to conduct the test more than once. The reflex is graded by the strength of the foot and toes going backward and toes splaying.
The Babinski reflex should be exhibited on both feet at the exact same time; however, it, more than almost any other reflex, is commonly retained on one foot more than the other. This marks an efficient way to assess the most immature hemisphere: the foot with the stronger Babinski reflex is typically on the opposite side of the more immature brain. The only time this may not be the case is if the foot with the lower response does not feel the pressure of the stroking and/or on the side of lower tone. This is where experience can help with understanding and differentiating the reflex.
Testing the palmar grasp reflex (11:43)
Use the hard end of a small paintbrush to draw an X with firm pressure over the middle of the palm of the hand. Look for any contraction or withdrawal of the hand, fingers or even arm. If the reflex is strong, the whole hand may contract and grab the brush. Otherwise, you may see quick but clear contractions and a partial closure of the fingers. In some cases, the hand will contract and the whole arm may jump. All of these represent different levels of retained reflexes in the 0-4 scale.
Testing for the rooting reflex (13:31)
You can self-assess for this reflex. Taking a brush, start slightly below the cheekbone on one side and then, firmly pushing on the brush, draw a straight line down to the corner of the mouth, brush over both lips and touch the other corner of the mouth. Do this three times on either side and grade the severity on the third try.
Then, stroke the brush from the chin directly toward the mouth on the same side three times. Similarly, grade the severity on the third try. Finally, complete the exact same procedure from the cheek and from the chin to the corner of the mouth and over the lips on the opposite side, then grade its severity.
The presence of and/or asymmetry of the reflex is a sure sign of a brain imbalance. During the test, look for contractions around the mouth and cheek. The most severe level (4) is if you open your mouth fully, turn toward the brush, and attempt to latch on and suck. There is often a consistent contraction of the lips that may look like a smile, but when it happens each time, it is clearly a reflex. There can be many variations; we have observed the whole face twitch on one side or the other. It can also be as subtle as a slight contraction of the bottom or top lip, which may be considered a 1 in severity. Again, it should not be there at all — and any amount is interfering with integration of the nervous system.
Testing for the snout reflex (15:15)
You can self-assess for this reflex. Take the hard side of the paintbrush and hold it vertically to your mouth, brush side down. Or you can use your finger.
Traditionally, to test for the reflex, you would press on the upper lip/philtrum area with the brush or your finger. However, I find it most effective when the examiner presses firmly on the upper and bottom lip at the same time, holding for three to five seconds and watching for a response (the closing of the mouth and puckering of the lips into the brush).
If the reflex is present, you will close and pucker up like a kiss. If the reflex is present in a strong way, you can press on the corner of the mouth and it will cause the lips to close and pucker. If the reflex is not present, there will be no movement of the face or lips (a 0 on our grading scale, while full lip puckering would be a 4).
Testing the Asymmetric Tonic Neck Reflex - supine (16:01)
Have your partner turn your head in one direction all the way and then slightly more. Have them hold this position. If the reflex is still present, they will see the arm and leg on the side of the head turn start to straighten out and possibly fully extend. On the opposite side, the arm and leg will slowly bend or flex and may end up fully flexed. Then, have them bring the head to the neutral position and turn it all the way in the opposite direction — and then slightly more. Have them hold for at least five seconds or until both arms and legs finish moving. Repeat three times on either side, grading the severity on the third time.
Testing the Moro reflex - supine (17:54)
Lay supine, in a face-up position with arms at their side and legs flat. Have your partner lift your head up all the way into flexion, then quickly thrust it down toward the table (taking care not to bang your head on the table!), only about two to three inches.
This simulates falling backward, which is what activates the Moro reflex if it is still active. Repeat this three times and watch if the hands, arms or legs fly up or off the table. It can range from the fingers and hands extending slightly to the entire body jumping. You may also see an immediate increase in pulse rate and face flushing.
Hemisphericity - Left-Right Balance (coming soon!)
Core Stability
Our postural reflexes come online after our primitive reflexes become integrated during our first year of life. If primitive reflexes don’t integrate, then often these postural reflexes never get switched on fully.
Having good core stability is crucial to brain health and proprioception, which is knowing where our body is in space.
Most of these exercises specifically train unconscious postural muscles.

Do as many push ups as you can.

2) Integration
Integrating retained primitive reflexes and supporting healthy neurological development at any age can be approached by using stimulation and exercises focused on 3 areas:
1) Primitive Reflex Integration
2) Hemispheric Balancing - providing stimulation to the under-active brain hemisphere
3) Improve Core Stability and your connection to your own body
Primitive Reflex Integration
Level 1 Exercises
Below, you will find the Level 1 exercises for integrating retained primitive reflexes. Do the exercises that correspond to the reflexes that were found retained on your exam. Doing all the exercises together takes about 5 minutes. You should aim to do these exercises 2-3 times a day. The more often you do them, the faster the reflexes will integrate.
Time stamps for each exercise in the video:
- Babinski - Ball Roll: 0:52
- Palmar - Ball Squeeze: 2:07
- Moro - Starfish: 3:10
- Tonic Labyrinthine Reflex (TLR) - Cannonball: 4:20
- Asymmetric Tonic Neck Reflex (ATNR) - Lizard: 5:04
- Spinal Galant - Snow Angels: 6:23
- Symmetric Tonic Neck Reflex (STNR) - Cat Stretch: 7:19
- Rooting Reflex - Brushing: 8:16
Babinski Reflex Integration
Level 1 - Ball Rolling
Roll a tennis ball on the outside part of the bottom of the foot. You can do this 10 times each side. Or you can do 20 times on the foot opposite the side of the brain you need to stimulate (for a right brain deficit, 20 times on the left, and for a left brain deficit, 20 times on the right) and then do 10 times on the other side.
Be sure to roll the ball nice and slowly, with decent pressure, paying attention to the sensations coming up through your foot.
Palmar Reflex
Level 1 - Ball Squeezing
Squeeze a tennis ball in your hand, slowly and strongly. You want to squeeze and then release it slowly, paying attention to the sensations through your hand.
You can do this 10 times on each side. Or 20 times in the hand opposite the side of the brain that needs more stimulation (so 20 times on the left hand for a right brain deficit, or 20 times on the right hand for a left brain deficit) and then 10 times in the other hand.
Moro Reflex
Level 1 - Sitting Starfish
Sitting on chair, start from fetal position, hands curled in a fist and head bent forward, the right wrist over left wrist and the right ankle over left (crisscrossed). Open all the way up bending head all the way back with arms and legs stretched out, then go back to fetal position crossing left wrist over right and left ankle over right this time, repeat and go back to original position this is one rep. Do 10 reps.
Tonic Labyrinthine Reflex
Level 1 - Cannonball
Hold knees into chest and wrap arms around legs. Bring your head up to your knees so that your shoulders should leave the ground as you curl into a tight ball, try to hold for 15 seconds and release. Do this for 10 times.
Asymmetric Tonic Neck Reflex (ATNR)
Level 1 - Lizard
Lying on your stomach, head turned to one side, the arm and leg are extended straight down on the side of head turn, the arm and leg on other side are bent.
Starting with the head, lift the head turning it and at the same time bend the arm and leg that were straight while straightening the bent arm and leg. Then repeat on the other side to come come back to the original position. This is one rep. Do 10 reps.
You can also stimulate this reflex directly - while on your hands and knees, do right head turn than left 10 times: Trying to go a little farther each time with each turn.
Spinal Galant Reflex
Level 1 - Snow Angels
Lying on the back, start with arms at the side and legs together. Then, open up arms and legs together and slow as far as possible and bring the hands together over the head and legs spread apart at the same time. Then slowly go back to original position; 10 reps.
Symmetric Tonic Neck Reflex
Level 1 - Cat Stretch
On hands and knees with your eyes open, bend your head all the way back and look up to ceiling and then bend head all the way down to look through the knees; 10 times.
You can also do the stimulation for the reflex. On your hands and knees with eyes open again, move your head up and down quickly through the full range of motion 10 times.
Rooting Reflex
Level 1 - Brushing
Take a small brush (a clean pain brush or make up brush works well) stroke from the cheek down to corner of mouth and then across both lips 5 x’s; then from Chin toward corner of mouth and across lips again 5 x’s; repeat this on the other side of face.
You can also use the back end of a vibrating toothbrush - vibrate over lips and then hold the toothbrush on the back of tongue for 30 secs to 1 minute.

Snout Reflex
Pressing on filtrum
The integration for the snout is the same as the test. You can use your finger to press on the filtrum to trigger the reflex action, which is a puckering of the lips. It may be more effective to use a brush handle or similar - make sure that the brush handle is pressing on the filtrum and on the bottom lip.
Brain Balancing
How to Balance Your Brain
When brain development doesn't proceed optimally or we have chronic health issues that cause certain changes, different areas of our brain become disconnected from one another and in almost every case, one hemisphere of the brain becomes more developed and active than the other.
The sections below cover tools and strategies for using different senses to stimulate your brain in specific ways. Layering these approaches together makes them more powerful.
You should aim to stimulate the under-active side of your brain according to your exam results and questionnaires and emphasize modalities that were indicated for you. For example, if your sense of smell was very low then you'll want to be sure to include this in your program.
Because there are a lot tools here, it's completely appropriate to start with a few of these and do them consistently. Once they become easy, you can layer more in.
Electrical Stimulation
The Brain Driver
The Brain Driver is a Transcranial Direct Current device.
Be sure to wet the pads with saline solution or water with salt added before using it. Saturate the pads and then squeeze out the excess water.
Place the red one (which is the positive anode) over the under-active side and the black one (the negative cathode) on the other side. The red pad will activate the cells underneath it and the black will inhibit.
Start off by using the lowest output setting, which is 0.5 mA for 20 minutes once or twice a day. Gradually increase over days or weeks, depending on your comfort level, to the highest output, which is 2.0 mA. You can use it for 30 minutes once or twice a day.

TENS Stimulation
You can use a TENS machine to stimulate the area between your spine and shoulder blade to active the opposite brain hemisphere. You can use this at the same time as the Brain Driver.
Smell
Healing the Brain Using Smell
1) Simple Aromatherapy
Put a couple of drops of an essential oil on the collar of your shirt that's on the same side as the side of your brain that you want to stimulate. So place it on your right collar to stimulate the right side or the left collar to stimulate the left side.
You can choose specific scents from the list below and apply 2-3 times per day. It's best to rotate 3 or 4 of these so that you don't habituate and maximize the stimulation.
2) The Smell Game
Place about 3 drops of each essential oil on a cotton ball and place the cotton ball in a dark jar. You can label the bottom of the jar so you can find out if you correctly identified the smell.
Close one nostril so that the nostril on the same side as the side of the brain you want to stimulate is open for smelling. Quiz yourself to see if you can identify the different scents. You can also see if you can improve your sensitivity so that you can begin to detect the smell from further away over time.
What you need for the smell game
Balance
Accessing Balance through the Vestibular System
1) Spinning & Eye Movements
The aim here is to stimulate post rotational nystagmus (PRN). You can do this if your vestibular system was found to be under-active on one side on your exam.
Spinning fast:
- to the right to stimulate the right hemisphere
- to the left to stimulate the left hemisphere
2 seconds per rotation at least 10 times, repeat until you can notice Nystagmus (beating) of eyes: 2-3 times a day
2) Optodrum
On your phone using the Optodrum app, use the black and white stripes:
- to the right and down to stimulate the right hemisphere
- to the left and up to stimulate the left hemisphere
Do this for 30 secs -1 minute: 2-3 times a day.
Sound
Healing Through Sound
Sound and Light Stimulation
You can use the flashing sound alone at 54 beats per minute for 30 seconds to 1 minute:
- use in the left ear to stimulate the right hemisphere
- use in the right ear to stimulate the left hemisphere
You can also add the Photic Stimulation of the Flashing light using the same side as you used for the sound.
Sight
Accessing the Brain Through the Eyes
Light Stimulation
Using altered glasses, look only out of:
- the right eye to stimulate the left brain
- the left eye to stimulate the right brain
You can do this for 30 minutes to an hour at a time.
🔗 Safety glasses for taping over according to the hemisphere you want to stimulate
Rhythm
Syncing the Brain through Rhythm
Training Rhythm Through Movement
Do circular movements, clap to match the sound of the metrotimer or metronome at 54 beats per minutes start at 20 reps, each week add 10 till get to 100 reps 1-2 times a day.
Using the same 54 BPM, tap your feet to the metronome sound, starting at 20 reps and adding 10 each week until she reaches 100.
Additionally, dancing is another great way to train rhythm through movement.
Training Rhythm Through Music
If you're interested in learning an instrument in order to train rhythm in your brain, there's a site called The Brainjo Academy, which is a lot of fun. It's a brain-based approach to learning an instrument for adults. It includes lessons for banjo, fiddle, ukele and piano.
Core Stability Exercises
The exercises are identical to the Core Stability Assessment above. You can look at the video and exercise descriptions. Once you have determined which level you are starting at then write down your current core stability exercise plan with exercises from each category:
- Supine bridge
- Lateral core
- Prone core
- Brachiation
- Sit ups - as many as you can in a minute
- Push ups - as many as you can
Aim to do these exercises once or twice a day.
