Vestibular involvement in spasmodic torticollis.

A M Bronstein, P Rudge

Journal of Neurology, Neurosurgery, and Psychiatry

|March 1, 1986

Summary

Spasmodic torticollis often involves vestibular system dysfunction, specifically directional preponderance of nystagmus opposite head deviation. This vestibular abnormality persists even with head fixation, suggesting central nervous system involvement.

Background:

Spasmodic torticollis is a movement disorder characterized by involuntary neck muscle contractions.
The underlying pathophysiology of spasmodic torticollis is not fully understood, with potential contributions from central and peripheral mechanisms.
Vestibular system function is crucial for head and eye movement coordination.

Purpose of the Study:

To investigate vestibular system findings in patients diagnosed with spasmodic torticollis.
To identify consistent vestibular abnormalities associated with spasmodic torticollis.
To explore the relationship between vestibular findings and disease duration.

Main Methods:

Review of vestibular findings in 35 patients with spasmodic torticollis.
Assessment of vestibular nystagmus in the dark and with optic fixation.
Evaluation of nystagmus during head rotation with and without fixation.
Analysis of smooth pursuit and optokinetic nystagmus.

Main Results:

A directional preponderance of vestibular nystagmus was observed in over 70% of patients, typically opposite to the direction of head deviation.
This directional preponderance remained even when the head was rigidly clamped during rotation.
The frequency and severity of directional preponderance decreased with optic fixation and were influenced by disease duration.
Smooth pursuit and optokinetic nystagmus were infrequently affected.

Conclusions:

The findings suggest a primary involvement of the vestibular system in spasmodic torticollis.
A breakdown in central sensory processing mechanisms for head and eye orientation may underlie the observed vestibular abnormalities.
Vestibular assessment can provide valuable insights into the neurophysiological basis of spasmodic torticollis.
