Why does my head bob when I walk?
Human walking has a peculiar straight-legged style. Consequently, the body’s centre of mass (CM) moves up and down with each step, which is noticeable in their up and down head bobbing while walking. Actually, walking flat makes the muscles work in unfavourable conditions that waste energy.
What does head bobbing mean in adults?
Essential tremor is by far the most common cause of head tremor. Another cause is cervical dystonia, also known as spasmodic torticollis. Head tremor may also occur in patients with Parkinson’s disease. Stroke, head injury, and multiple sclerosis are other causes of tremor but are less likely to cause head tremor.
Why do I go up and down when walking?
Therefore, not only do humans bob up and down in normal walking to save energy via a pendulum-like mechanism, as commonly thought since the 1960s, but they also load their muscles more efficiently this way. Efficient locomotion is when most of the metabolic energy input is transformed into mechanical work.

Spasmus nutans is a disorder affecting infants and young children. It involves rapid, uncontrolled eye movements, head bobbing, and sometimes, holding the neck in an abnormal position.
How is spasmus nutans diagnosed?
As previously discussed, the diagnosis of spasmus nutans warrants neuroimaging, usually MRI, as this is generally more sensitive in revealing pathology in anterior visual pathway i.e. optic nerve glioma than CT scan.
