What is the reason for a four-month-old baby’s hand shaking?

It is very interesting to have a baby of a few months old at home. For the baby's parents, it is really gratifying to see the baby growing day by day under their care and attention. However, the baby may encounter some problems during the growth process. In this case, you should observe the child's condition more often and have regular physical examinations when necessary. So, what is the reason for the trembling of the four-month-old baby's hands?

Hand tremors are divided into physiological tremors and pathological tremors.

Physiological hand tremors have small amplitudes and fast speeds, and often occur when the hand is stationary. They are small, fast, and irregular tremors. Physiological hand tremors often occur when one is under mental stress, fear, emotional excitement, severe pain, or extreme fatigue. Once the above causes of hand tremors are eliminated, the hand tremors will also disappear.

Pathological hand tremor, medically known as "tremor", refers to involuntary tremors of the hands, which are often permanent. There are two main types of hand tremors: static hand tremors and dynamic hand tremors. Among them, static hand tremor is the hand tremor that occurs when the muscles are completely relaxed, that is, in a quiet state. This type of hand tremor disappears during sleep, with a frequency of 4-6 times per second and a relatively regular pattern. It is a typical disease such as Parkinson's syndrome.

Sports tremor is a tremor that only occurs during exercise, and the tremor becomes more severe when the movement approaches the target. For example, when a doctor performs the finger-to-nose test on a patient, he asks the patient to straighten his forearm and then point his index finger at the tip of his nose. The closer the tip of the index finger is to the tip of the nose, the more obvious the hand tremor will be. Motor tremors are irregular, with large amplitudes, and are aggravated by emotions. They are common in lesions of the cranial nerves and upper limb nerves.

It is necessary to look specifically at the manifestations of the so-called shaking of the child, and to rule out the possibility of convulsions or other abnormalities based on the amplitude and frequency of the shaking. If there are obvious rhythmic twitches or shaking, you must seek medical attention or record the child's performance yourself and ask the doctor to confirm. If convulsions can be ruled out, it is considered to be related to the child's incomplete brain development. It is recommended to supplement cod liver oil to promote calcium absorption, thereby improving the symptoms of hand tremors, and pay attention to keeping warm and not catching cold.
