Pediatric fibromyalgia (FM) & dizziness: evaluation of vestibular function

Twelve children with fibromyalgia and complaints of chronic

dizziness were evaluated with both clinical office maneuvers

of vestibular function and laboratory tests composed of

electronystagmography and sinusoidal harmonic acceleration

rotary chair testing. All test results were normal for

spontaneous nystagmus with or without visual fixation,

oculocephalic reflex, dynamic visual acuity, head-shaking

nystagmus, Quix test, and Dix-Hallpike maneuver.

Electronystagmography test results were essentially normal for

saccades, gaze, Dix-Hallpike, pendular tracking, and caloric

evaluation. Rotary chair testing was normal in all 12

patients. These findings suggest that central (brainstem) and

peripheral vestibular (inner ear) mechanisms do not account

for the complaints of dizziness in the pediatric patient with

fibromyalgia. The common musculoskeletal abnormalities of

fibromyalgia may affect their proprioceptive orientation,

therefore giving them a sense of imbalance.
