Abstract:
A 63-year-old man presented with 4 years of orthostatic tremor while standing, resolving after sitting or leaning against a wall. There was marked subjective unsteadiness, but no falls. Surface EMG in arms and legs demonstrated a 14- to 16-Hz synchronous tremor in antagonist muscles (video on the Neurology Web site at www.neurology.org.).

The Vestibular System
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.
Alterations in Muscle Tone ll
Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...
