Dear Sir,

Pseudo-orthostatic tremor (PsOT) is a rare movement disorder recently included in the latest classification of tremors [1]. It shares notable clinical features with primary orthostatic tremor (OT); in fact, it presents at lower limbs mainly during standing, and it causes unbalance that improves during walking.

Actually, PsOT shows a lower frequency in comparison to the primary form because PsOT frequency is around 10 Hz whereas primary OT typically presents a frequency higher than 13 Hz [2].

Here, we describe a case of pseudo-OT not associated with other neurologic disorders.

Case report

A 23-year-old man was admitted to our hospital because of a severe leg tremor. Patient reported a mild leg tremor since he was 14, and only recently, after an unexplained weight loss, the movement disorder worsened and became disabling. Clinical examination showed severe legs shaking in upright position that was almost not evident during walking. Postural tremor was also present only at lower...
