Some infants frequently arch their necks and backs, especially when they’re uncomfortable or upset. While occasional arching can be a normal part of early development, persistent, forceful, or abnormal arching may be a sign of underlying issues that require further attention. Arching is commonly seen in babies with reflux or colic, where stomach acid or trapped gas can lead to discomfort. In cases of reflux, arching is often accompanied by other signs such as frequent spit-up, irritability after feeding, or trouble lying flat. Colic, on the other hand, is typically characterized by prolonged crying episodes, often occurring in the evening, and may be linked to gastrointestinal or nervous system sensitivity.
Another possible explanation is something called ‘dural tension’. The dura mater, a connective tissue that surrounds the brain and spinal cord, adheres to the vertebral column and cranial bones. When tension, tightness, or irritation is present in the dura, it can cause discomfort in an infant, leading them to arch their backs in an attempt to relieve it. Many of these infants with dural tension may move in stiff ways, may have tightness in their joints, and may commonly seem to be physically uncomfortable. For example, by 3 months of age, children should have more relaxed hands, but kids with dural tension may still hold their hands in a tight fist.
According to research and pediatric practitioners, dural tension may impact the nervous system, leading to issues beyond physical discomfort. Potential symptoms include poor sleep patterns, difficulties with feeding and latching, and excessive crying. Given that the nervous system is still developing in infants, even the slightest imbalances or irritations can have noticeable impact. This is particularly true in the first three months of life, a period sometimes referred to as the “fourth trimester”.
In terms of conservative treatment, pediatric-focused chiropractors use gentle techniques, such as craniosacral therapy, a special spinal adjustment called sustained contact, or gastrointestinal massage, to help relieve this tension. These approaches focus on enhancing mobility and alignment of the spine and cranial bones, which may help alleviate pressure on the nervous system. While higher-quality research is needed to confirm these connections, early observation and supportive care can make a big difference in a baby’s development and well-being.
