Comparison of sensorimotor disturbance between subjects with persistent whiplash associated disorder and subjects with acoustic neuromas
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.
Repeated measures, case controlled.
Tertiary institution and metropolitan hospital.
Twenty subjects with persistent whiplash, 20 subjects with acoustic neuroma, and 20 control subjects.
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.
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).
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.
