Abstract
Treleaven J, LowChoy N, Darnell R, Panizza B, Brown-Rothwell D, Jull G. Comparison
of sensorimotor disturbance between subjects with persistent whiplash-associated disorder
and subjects with vestibular pathology associated with acoustic neuroma.
Objective
To determine if differences exist in reported symptoms and in outcomes of sensorimotor
tests (cervical joint position error [JPE], neck-influenced eye movement control,
postural stability) between subjects with persistent whiplash and subjects with unilateral
vestibular pathology associated with acoustic neuroma.
Design
Repeated measures, case controlled.
Setting
Tertiary institution and metropolitan hospital.
Participants
Twenty subjects with persistent whiplash, 20 subjects with acoustic neuroma, and 20
control subjects.
Interventions
Not applicable.
Main Outcome Measures
Symptom descriptors, Dizziness Handicap Inventory (short form), measures of cervical
JPE, the smooth pursuit neck torsion (SPNT) test, and forceplate measures of postural
stability in comfortable and narrow stances.
Results
The results showed differences in SPNT (P=.00), selected measures of postural stability (P<.04), and reported symptoms between the whiplash and vestibular groups. There was
no between-group difference in cervical JPE (P>.27) or dizziness handicap (P>.69).
Conclusions
This study showed differences in sensorimotor disturbances between subjects with discreet
whiplash and those with vestibular pathology associated with acoustic neuroma. The
results support the SPNT test as a test of cervical afferent dysfunction. Further
research into cervical JPE as a discreet test of cervical afferentation is warranted.
