Pseudo-orthostatic tremor: description of a not typical case
- 12 Downloads
Pseudo-orthostatic tremor (PsOT) is a rare movement disorder recently included in the latest classification of tremors . 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 .
Here, we describe a case of pseudo-OT not associated with other neurologic disorders.
