Introduction
1. Vestibular hypersensitivity—The most common manifestation is motion sickness (e.g., car sickness). 2. Abnormal posture—Abnormal static postures (e.g., tonic neck reflex posture) are observed at rest; abnormal dynamic postures are most frequently seen in hypotonic, ataxic, and spastic types. 3. Speech/language disorders—Consistent errors in verbal expression occur. 4. Picky behavior, irritability, and an inability to remain calm.

In daily life, the human body primarily relies on peripheral receptors within three sensory systems—the vestibular, visual, and proprioceptive systems—to detect body position, movement, and external stimuli. Information from these systems is integrated and coordinated by central balance-processing centers to maintain optimal body positioning in space. So, what are the manifestations of vestibular dysfunction? Below, we provide an overview.

Manifestations of Vestibular Dysfunction

1. Vestibular Hypersensitivity

Children with vestibular hypersensitivity commonly experience motion sickness—especially car sickness—and often feel dizzy or nauseated during activities involving rocking or spinning. Such children typically move slowly or cautiously, appearing timid or fearful. They prefer sedentary games or activities, avoid swinging on swings, and frequently seek adult protection.

2. Abnormal Posture

Postural abnormalities may occur both at rest and during movement. Resting postural abnormalities include tonic neck reflex posture, opisthotonic (arched-back) posture, decerebrate rigidity, and hemiplegic posture. Abnormal postures during movement are most frequently observed in children with hypotonic, ataxic, or spastic types of cerebral palsy—for example, choreoathetosis and dystonia, spastic hemiplegic gait, spastic paraplegic gait, and cerebellar ataxic gait.

3. Language Impairment

When present in children, this condition can impair physical activity, disrupt proper cognitive processing between the left and right brain hemispheres, and lead to mental disorganization. In severe cases, it may result in delayed language development. Key manifestations include poor gravitational security (i.e., unstable sense of balance), impaired motor planning, difficulty controlling limbs accurately, inability to maintain stable posture (leading to frequent falls), inability to perform symmetrical movements with both hands and feet, and language deficits—including frequent errors in verbal expression.

4. Selectivity and Behavioral Challenges

Children with such difficulties may also display pickiness, irritability, and an inability to remain calm. At school, they often underperform, fidget excessively, struggle to improve academically, have difficulty concentrating during class, lack self-confidence, and exhibit poor social skills—such as reluctance to share with peers or even disruption of classroom discipline and resistance to teacher instructions. These behaviors should not be dismissed merely as “naughtiness”; they may instead indicate an underlying medical condition requiring prompt intervention.
